We report the case of a patient previously treated with an iliac branch endograft for isolated iliac artery aneurysm who developed, more than 2 years later, a type B aortic dissection resulting in the acute expansion of the previously excluded iliac aneurysm. Successful endovascular salvage is described.
Our objective was to evaluate thè cardiovascular (CV) risk among pts treated for more than 5 years with regimens based on NVP or EFV examining traditional risk factors, and detecting thè presence of subclinical vascular lesions by means of colour Doppler ultrasonography. 276 pts have been evaluated. 156 of them in treatment with NVP, 120 with EFV. Data regarding risk factors for CV, have been evaluated at thè start of therapy (TO) and periodically re-checked. The pts were submitted to ultrasound at TO and at FU. At TO data regarding gender, age, period of treatment, percentage of HAART naives pts, risk factors for CV disease did not statistically differed between thè two groups. Comparing thè data at TO and at FU within NVP group, total cholesterol (TC), LDLc and triglycerides (TG) showed a significant decrease, HDLc increased significantly, while glycaemia and BMI did not show variations. In 67 pts (36 in NVP, 31 in EFV) ultrasound was available al TO and at FU. In NVP group ultrasound data did not show significant changes, while in EFV group thè number of pathologic findings significantly increased. Comparing thè two groups at TO and at FU, pts in NVP group had significantly higher values of TC, LDLc and TC at TO while, at FU, TC and LDLc become non significantly different, while TG become lower with respect to EFV group. Glycaemia was comparable at TO, while it become significantly lower in NVP group. Our data show a better lipid and glucose profile in NVP group, with a tendency to decrease of TC, LDLc and TG, and to increase of HDLc; while in EFV group we observed a tendency to thè increase of TC, LDLc, TG, BMI and glycaemia. However, being thè value of TG, thè only statistically different at FU, we conclude that both thè regimens seem generally safe among long-term treated pts. However, pts in EFV group show a significant tendency to develop a pathologic ultrasound finding with respect to NVP group. Both these regimens seem generally safe, although pts treated with NVP show a better lipid and glucose profile and a lower tendency to develop subclinical atherosclerotic lesions.
OBJECTIVES: The aim of this study was to evaluate the cardiovascular risk among patients treated for more than 5 years with regimens based on nevirapine or efavirenz. PATIENTS AND METHODS: A total of 276 patients were retrospectively evaluated, 156 of whom were treated with nevirapine and 120 with efavirenz, by examining traditional risk factors and detecting the presence of subclinical carotid lesions with colour-Doppler ultrasonography. RESULTS: When comparing the data at baseline and follow-up in the nevirapine group, total cholesterol, low-density lipoprotein cholesterol (LDLc) and triglycerides showed a significant decrease, while high-density lipoprotein cholesterol increased. Ultrasound data, obtained in a subgroup of 67 patients, did not show significant changes for those treated with nevirapine. In the efavirenz group, total cholesterol, LDLc, triglycerides, glycaemia, body mass index and the number of patients with a pathological ultrasound significantly increased. When comparing the two groups at baseline and follow-up, nevirapine patients had significantly higher values of total cholesterol, LDLc and triglycerides at baseline, while total cholesterol and LDLc differed non-significantly at follow-up; triglycerides became significantly lower in the nevirapine arm with respect to the efavirenz group. Glycaemia was comparable between the two groups at baseline, while it was significantly lower in the nevirapine group at follow-up. The number of pathological ultrasound findings was significantly higher in the efavirenz group at follow-up. CONCLUSIONS: Patients treated with nevirapine demonstrated a better lipid and glucose profile and a lower tendency to develop subclinical atherosclerotic lesions.
The aim of this study was to evaluate outcomes and feasibility of carotid artery stenting versus carotid endarterectomy, both procedures performed in the same patient. Forty-five subjects (33 males, 70 ± 7 years) underwent carotid endarterectomy or carotid artery stenting, the counter procedure on the contralateral carotid performed after a variable period. We evaluated the post-procedural percentage of carotid stenosis at 30, 180 days and one-year follow-up, and the occurrence of acute myocardial infarction, New York Heart Association class progression, stroke, death, cardiovascular death, angina, transient ischemic attack and renal failure. Carotid artery stenting treatment reduced the degree of re-stenosis after 180 days equally to carotid endarterectomy procedure (difference: 0.033%, P = 0.285). No statistically significant differences were observed according to the occurrence of acute myocardial infarction and New York Heart Association class progression, revealing odds ratio (OR) equal to 0.182 (P = 0.361) for acute myocardial infarction and 0.303 (P = 0.434) for New York Heart Association class progression. Carotid endarterectomy confirms its efficacy in carotid revascularization, but carotid artery stenting constitutes a good alternative when the procedures are selected based on patient-specific risk factors
BACKGROUND: Aim of this study was to retrospectively compare perioperative (<30 days) and 2-year results of open and endovascular management of popliteal artery aneurysms (PAAs) in a single-center experience. METHODS: From January 2005 to December 2010, 64 PAAs in 59 consecutive patients were operated on at our institution; in 43 cases, open repair was performed (group 1), whereas the remaining 21 cases had an endovascular procedure (group 2). Data from all the interventions were prospectively collected in a dedicated database, which included main preoperative, intraoperative, and postoperative parameters. Early results in terms of mortality, graft thrombosis, and amputation rates were analyzed and compared by χ(2) text or Fisher exact text. The surveillance program consisted of clinical and ultrasonographic examinations at 1, 6, and 12 months and yearly thereafter. Follow-up results (survival, primary and secondary patency, limb salvage) were analyzed by Kaplan-Meier curves, and differences in the two groups were assessed by log-rank test. RESULTS: There were no differences between the two groups in terms of sex, age, risk factors for atherosclerosis, and comorbidities; PAAs were symptomatic in 48% of cases in group 1 and in 29% in group 2 (P = 0.1). Fifteen patients with mild-to-moderate acute ischemia due to PAA thrombosis underwent preoperative intra-arterial thrombolysis, 13 in group 1 and 2 in group 2. In open surgery group, nine cases were treated with aneurysmectomy and prosthetic graft interposition, and in seven cases, the aneurysm was opened and a prosthetic graft was placed inside the aneurysm. In 27 cases, ligation of the aneurysm with bypass grafting (21 prosthetic grafts and 6 autologous veins) was carried out. In group 2, 20 patients had endoprosthesis placement, whereas in the remaining patient, a multilayer nitinol stent was used. There was one perioperative death in a patient of group 2 who underwent concomitant endovascular aneurysm repair and PAA endografting. Cumulative 30-day death and amputation rate was 4.5% in group 1 and 4.7% in group 2 (P = 0.9). Follow-up was available in 61 interventions (96%) with a mean follow-up period of 22.5 months (range: 1-60). Estimated primary patency rates at 24 months were 78.1% in group 1 and 59.4% in group 2 (P = 0.1). Freedom from reintervention rates at 24 months were 79% in group 1 and 61.5% in group 2 (P = 0.2); estimated 24-month secondary patency rates were 81.6% in group 1 and 78.4% in group 2 (P = 0.9), and freedom from amputation rates were 92.7% and 95%, respectively (P = 0.7). CONCLUSIONS: Endovascular treatment of PAAs provided, in our initial experience, satisfactory perioperative and 1-year results, not significantly different from those obtained with prosthetic open repair in patients with similar clinical and anatomical status. There is, however, a trend toward poorer primary patency rates among patients endovascularly treated, who also seem to require more frequently a reintervention.
BACKGROUND: To retrospectively analyze early and follow-up results of endovascular management of visceral artery aneurysms (VAAs) in a single-center experience. METHODS: From 2007 to June 2013, 26 consecutive elective endovascular interventions for VAAs were performed in 26 patients; preoperative, intraoperative, and postoperative data were prospectively collected in a dedicated database. Early (<30 days) and follow-up results were evaluated. RESULTS: The site of aneurysm was splenic artery in 17 patients, common hepatic artery in 3 patients, renal artery and pancreaticoduodenal artery in 2 cases each, and gastroduodenal artery and celiac trunk in one case each. All the lesions were asymptomatic, and the mean diameter was 22.8 mm. Interventions consisted in coiling in 19 cases; in 4 patients a covered stent was placed, whereas the remaining 3 patients had a multilayer stent. Technical success was 89%. There were no perioperative deaths; 1 patient with splenic artery aneurysm had coils migration with symptomatic splenic infarction and underwent successful redo coils packing. Median duration of follow-up was 18 months. During follow-up, 1 aneurysm-unrelated death occurred. One asymptomatic thrombosis of a treated vessel was recorded, with a 2-year estimated patency rate of 91%. Mean aneurysmal diameter at the latest follow-up was 20.2 mm (P = 0.001 in comparison with preoperative values; 95% confidence interval 1.9-5.2). Complete exclusion of the aneurysm occurred in all but 1 patient, who had a limited increasing in the diameter of its splenic aneurysmal sac after coiling. Another patient developed a more distal aneurysm of the splenic artery after 24 months. No reinterventions were required. Freedom from aneurysm-related complications at 2 years was 72.9% (Standard Error, 0.09). CONCLUSIONS: In our experience, endovascular treatment of VAA, when feasible, provided excellent perioperative results with low rates of complications and reinterventions. Even if the risk of developing aneurysm-related complications during follow-up is substantial, most of them can be watched without the need for repeated interventions.
Aneurysms of the brachiocephalic trunk are rare but their clinical outcomes are potentially devastating; they include rupture, cerebral or arm ischemia secondary to thromboembolism, and compression of the surrounding structures. Although open repair has proven successful, it is associated with significant morbidity and mortality rates. Endovascular treatment, if anatomically feasible, may offer a safer and less invasive approach to these lesions, especially in high-surgical-risk patients. We report the good long-term outcome of endovascular repair of a large innominate artery true aneurysm due to Takayasu's arteritis. A stent graft was safely and successfully deployed to exclude the aneurysm; assessment by vascular imaging at 8-year follow-up demonstrated the efficacy of the procedure.
To report the use of endografts to manage multiple aneurysms due to Cogan syndrome (CS). A 38-year-old woman with descending thoracic aorta and right common carotid artery aneurysms due to CS was treated with endovascular grafts. After 4 years, angio computed tomography scan demonstrated complete exclusion of the aneurysms with no signs of endoleak, whereas echo color Doppler showed patency of the carotid graft, no signs of restenosis, no progression of the disease in the landing zones, and complete aneurysm exclusion. Endovascular repair seems to have favorable long-term outcomes and should be considered a viable alternative to surgery in unfit for open surgery patients, even if they are young, and when the aneurysm size and location would pose a higher risk of perioperative and postoperative complications after an open surgical procedure.
Purpose : To report the use of a endograft to manage a type IB endoleak in a patient with a juxtarenal aortic aneurysm previously treated with a multylayer stent CASE REPORT: Under compassionate use a 68 years old patient with a juxtarenal aortic aneurysm and multiple comorbidities was treated with a multilayer flow modulating stent. Twelve months later a new CT scan identified a type Ib endoleak with an increase of the aortic aneurysm size due to extension of the aneurysmal disease to the aortic carrefour . A new endovascular procedure was then performed , deploying an aorto bisiliac endoprosthesis . After 18 months serial echocolor duplex and CT scans have shown normal visceral arteries patency, no signs of endoleak and sac shrinkage of 5 mm CONCLUSION: In this case, MARS failed to treat the AAA and required a reoperation with conventional covered stentgraft for distal sealing, which may be considered a feasible solution to manage potential endoleaks
OBJECTIVE: The purpose of this study was to retrospectively analyze early and midterm results of endovascular infrainguinal peripheral revascularizations in female patients in our single-center experience, paying particular attention to clinical, anatomic, and technical factors affecting perioperative and follow-up outcomes. MATERIALS AND METHODS: From January 2000 to December 2010, 258 endovascular interventions for femoropopliteal disease were performed. Interventions were retrospectively divided into two groups: interventions performed in women (80 interventions, group 1) and interventions performed in men (178 interventions, group 2). The two groups of patients were compared in terms of demographic data, common risk factors for atherosclerosis, and comorbidities. Early (intraoperative and <30-day) results were analyzed in terms of technical success, conversion to open surgery, primary patency, secondary patency, and, for patients with critical limb ischemia, limb salvage. The follow-up program consisted of clinical and duplex scanning examinations with ankle-brachial index (ABI) measurement within the third postoperative month, at 6 and 12 months, and yearly thereafter. Follow-up results were analyzed in terms of survival, primary and secondary patency, assisted primary patency, and, for patients with critical ischemia, limb salvage. RESULTS: There were no differences between the two groups in terms of risk factors for atherosclerosis, comorbidities, clinical, and anatomic status. Technical success was 96.9% and technical failure rates were 1.2% in group 1 and 3.9% in group 2 (P = .2). Three in-hospital deaths were recorded, all in group 2, whereas in-hospital thromboses occurred in five patients, two in group 1 and three in group 2; with conversion to surgical bypass in all these cases, and in three of the cases, major amputation was necessary (two in group 1 and one in group 2). Cumulative 30-day mortality was 1.1%, with no difference between women (no deaths) and men (three deaths, 1.6%; P = .4). Overall amputation rate at 30 days was 1.2%, again with no differences between the two groups (2.5% and 0.6%, respectively; P = .4); also, the rate of perioperative thrombosis (overall 2.7%) was similar between the two groups (2.5% and 3.3%, respectively; P = .9). Mean duration of follow-up was 17 months (range, 1-85 months). Estimated 36-month survival rates were 95% in group 1 and 84.5% in group 2 (P = .4; log-rank, 0.7). Cumulative primary patency rates at 36 months were 38% in group 1 and 42% in group 2 (P = .4; log-rank, 0.5). Assisted primary patency at 36 months was 45.1% in group 1 and 60.5% in group 2, whereas secondary patency rates were 63.5% and 76%, respectively (P = .8; log-rank, 0.03). CONCLUSION: Endovascular treatment of femoropopliteal occlusive disease provides similar results between men and women at an intermediate follow-up. There is, however, a trend toward poorer results in women requiring further analysis at a longer follow-up period.
OBJECTIVE: To assess the association of high-sensitivity C-reactive protein (hsCRP) to adverse cardiovascular events and perioperative myocardial damage in patients after elective vascular surgery. METHODS: This was a prospective observational study in a tertiary-care teaching hospital, with 239 patients undergoing elective vascular surgery. The receiver-operating characteristic (ROC) curve was calculated to assess the optimal cut-off value of hsCRP. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Multiple logistic regression analysis was used to identify the predictors of the primary outcome. The primary outcome was a composite of periprocedural myocardial damage, defined as cardiac troponin I (cTn-I) elevation above the decision limit of 0.15 μg/L, death, acute coronary syndrome, stroke, acute heart failure, or intrastent thrombosis within 30 days of surgery. RESULTS: On ROC analysis, the optimal cut-off value of hsCRP was 3.2 mg/L. The primary outcome occurred in 48 patients (20.1%). On univariate analysis, smoking (P = .009), known hypercholesterolemia (P = .01), previous ischemic heart disease (P = .0003), open surgery (P = .03), and hsCRP levels (P < .0001) were associated with the primary outcome. On multiple logistic regression analysis, only hsCRP was independently associated with the primary outcome. The unadjusted and adjusted ORs for the primary outcome among patients with hsCRP levels >3.2 mg/L were 7.5 (CI, 3.7-15.2; P < .0001) and 4.6 (CI, 2.1-9.9; P = .0001), respectively. CONCLUSION: Our data suggest that higher levels of hsCRP are independently associated with an increased risk of perioperative myocardial damage and early adverse cardiovascular events in patients undergoing elective vascular surgery. This may have implications for risk stratification and therapeutic approach.
The distribution of peripheral arterial disease (PAD) shows that more than 15% of lesions are localized in thè femoro-popliteal area. Chronic total occlusions (CTOs) of thè superficial femoral artery (SFA) pose a particular challenge and have been considered a traditionally surgical field for many decades. In thè last years a wide range of therapeutic modalities have emerged addressing to thè endovascular treatment of stenosis and occlusions. The BASIL trial showed that thè rates of amputation-free survival after surgery and balloon angioplasty were similar, at least for thè first two years.1 Nitinol stents may be an effective alternative to surgical revascularization for longer lesions in patients with severe comorbidities. It has been demonstrated that stenting may be a suitable option for patients not eligible for saphenous vein grafts and thè 12-month patency data are similar to those for prosthetic bypass grafts with considerably lower rate of complications.2 On thè other hand, thè endovascular approach could be limited in a few patients by inability to enter thè lumen when there is a cylindrical calcification or a heavily calcified plaque involving thè common femoral artery (CFA) bifurcation with thè occlusion of thè SFA at thè origin. The purpose of this study was to investigate thè early and late outcome after complete recanalization of SFA occlusion by using of a hybrid technique.
Leiomyosarcomas are rare malignant tumors that particularly affect women. In 2% of all cases, they involve the veins, and in 60% of the cases affecting veins, an involvement of the inferior vena cava (IVC) has been demonstrated. We report a case of IVC leiomyosarcoma operated by resection and reconstruction with a Dacron bypass and apposition of an Adams-DeWeese IVC filter. The latter procedure has never been reported before in association with a graft applied for this disease. Technical and clinical details are described.
We present a rare case of a giant hepatic artery aneurysm in a 61-year-old man that was successfully treated by aneurysmectomy with prosthesis bypass grafting. Because the gastroduodenal artery was occluded, an adequate collateral circulation was not ensured after simple ligation, so a direct arterial flow to the liver was restored to avoid the risk of significant liver or biliary tract ischemia. A computed tomography scan at 1 month showed occlusion of the bypass. The patient remained asymptomatic, despite the supposed lack of adequate collateral circulation. The unpredictable blood supply to the liver is discussed.
A 66-year-old man with multiple comorbidities presented with a juxtarenal perianastomotic aortic aneurysm 10 years after open abdominal aortic aneurysm repair. The aneurysmal disease also involved both iliac bifurcations, the right internal iliac artery, the left common femoral artery (CFA) up to its bifurcation, and the homolateral popliteal artery. We performed bilateral internal iliac artery coil embolization 1-month apart. Later, we performed aortouniiliac endografting extending to the right external iliac artery and placement of an endovascular plug in the left external iliac artery. A right CFA to left femoral bifurcation bypass graft was then constructed after ligation of the left CFA aneurysm. After recovering from anesthesia and despite sequential hypogastric embolization, the patient developed postoperative paraplegia, buttock ischemia, and ischemic colitis and died on postoperative day 5. The possible pathogenic mechanisms involved in the onset of these ischemic complications are discussed in this article.
