RESUMO
BACKGROUND: Type 2 endoleaks (T2ELs) have been considered a benign condition and intervention is recommended when they are associated to sac expansion. The aim of this study was to report on T2EL embolization midterm outcomes, using neurointerventional material. METHODS: A single-center retrospective analysis of consecutive patients treated with transarterial embolization, using neurointerventional material, for T2EL after standard endovascular aortic aneurysm repair (EVAR) between January 01, 2017 and July 30, 2022, was undertaken. Primary outcome was technical success and secondary outcome was T2EL recurrence during follow-up. RESULTS: Twenty six patients [92.3% males, mean age 73.9 ± 7.7 years] were included. The median time between EVAR and T2EL diagnosis was 12 months (range: 1-84 months). In 38.5% of patients, T2EL was detected at first month after EVAR. The time to embolization was 18 months (range: 1-96 months). In 42.3% of cases, a patent inferior mesenteric artery was suspected to relate to T2EL formation while in 42.3% of cases, a lumbar artery. Twelve procedures (38.4%) were performed using coils and Onyx and 13 (50%), using only Onyx. Technical success was 84.6%. The mean follow-up was 24 months (range: 1-60 months), including 20 patients. In 30% of cases, an T2EL recurrence was detected. Three patients (11.5%) underwent secondary embolization. CONCLUSIONS: Transarterial embolization for T2EL, using neurointerventional material, provided acceptable technical success and T2EL recurrence rates at 2 years of follow-up. Longer follow-up data would further estimate the durability of the technique.

Descending thoracic aorta to femoral artery bypass is an effective and safe procedure for the treatment of aortoiliac occlusive disease when an approach to the abdominal aorta is undesirable. The major limitation of this technique has resulted from the morbidity rate associated with thoracotomy in a relatively high-risk vascular surgery population. As a minimally invasive procedure, videoendoscopy has been shown to improve the patient postoperative course and comfort in the field of general and thoracic surgery. The same benefits could be expected from a videoendoscopic surgery involving the thoracic aorta. In 2003 we reported the first case of a totally videoendoscopic descending thoracic aorta-to-femoral artery bypass procedure. In this article we report our additional experience with and the modifications we have made to this technique.

BACKGROUND: We report a hybrid treatment for a ruptured penetrating aortic ulcer (PAU) of the aortic arch in emergency conditions. METHODS: A 74-year-old man with severe comorbidity was diagnosed with a symptomatic rupture of a PAU of the aortic arch. As he was considered unfit for conventional open repair and it was an emergency condition, an acute endovascular repair with cervical debranching of the supra-aortic trunks could be proposed. The left common carotid artery and left subclavian artery were first debranched and revascularized through cervical access, and the endovascular stent graft was then deployed via femoral access in the aortic arch. At >or=2 years the patient is safe with no sign of progression of the disease. CONCLUSION: Acute debranching and stent grafting is feasible in emergency conditions to treat ruptured PAU of the aortic arch, with satisfying short- and mid-term outcomes, and can be proposed to patients considered unfit for conventional open repair.

We present an alternative surgical approach to popliteal artery entrapment syndrome with vascular complications in the absence of a suitable saphenous vein. Three patients (29, 35, and 78 years old) with thrombotic and/or aneurysmal lesions of the popliteal artery from popliteal artery entrapment syndrome were treated with superficial femoral artery autograft reconstruction. The procedure was performed through a medial approach. The superficial femoral artery was harvested in the upper third of the thigh and used as the conduit for reconstruction and the harvested segment was replaced by a polytetrafluoroethylene graft. At follow-up, patients were asymptomatic and duplex ultrasound revealed patent reconstruction with no morphological abnormalities.

OBJECTIVE: This prospective, observational study evaluated the safety and efficacy of superficial femoral artery autograft reconstruction in the treatment of popliteal artery aneurysms in the absence of a suitable saphenous vein. METHODS: From March 1997 to April 2007, data from patients with popliteal artery aneurysms treated by superficial femoral artery reconstruction were prospectively collected in two centers. The procedure was performed through a medial approach. The superficial femoral artery was harvested in the upper third of the thigh and used as the conduit for reconstruction, and the harvested segment was replaced by a polytetrafluoroethylene graft. The patients were observed for survival, limb salvage, and reconstruction patency. The results were calculated by the Kaplan-Meier method. RESULTS: During the 10-year study period, 37 popliteal artery aneurysms in 32 patients (all men; median age, 71 years) were treated by reconstruction using the superficial femoral artery. Indications for surgical treatment were symptomatic or complicated aneurysms in 11 (30%). Four (11%) of the 37 popliteal artery aneurysms were thrombosed, and 33 (89%) were patent. At surgery, 35% had a single vessel runoff. Because of acute ischemia, reconstruction was performed as an emergency procedure in three patients (8%). There were no perioperative deaths, early amputations, or early thrombosis. The mean follow-up period was 36 months (range, 7-103 months). Two grafts thrombosed during follow-up. At 3 years, the primary and secondary patency rates were 86% and 96%, and overall limb salvage was 100%. Follow-up duplex ultrasonography did not detect any aneurysmal dilatation of the autograft. CONCLUSION: Our experience shows that superficial femoral arterial reconstruction is a safe and useful treatment option in patients with popliteal artery aneurysms who lack suitable saphenous veins. This reconstruction seems to be a good alternative to prosthetic bypass crossing the knee joint, and our results suggest that this study should be continued.

The aim of this work was to evaluate, in terms of activity and immediate postoperative results, the modifications of our elective surgical treatment of infrarenal abdominal aortic aneurysms (AAAs) resulting from the use of stent grafts to treat AAAs, following the recommendations issued by the French Health Products Safety Agency (AFSSAPS) in December 2003. This monocentric and retrospective study used the clinical data of patients operated on for asymptomatic AAA between January 2001 and December 2006. Endovascular treatment of AAAs with aortic stent grafts was introduced in our current practice in January 2004, following the recommendations of the AFSSAPS (high-risk patients for open surgery presenting with an AAA > or =50 mm). Group I was composed of patients operated on between January 2001 and December 2003 according to the standard open technique. Group II was composed of patients operated on between January 2004 and December 2006 with either standard open surgery or endovascular surgery. The main criteria of evaluation were the number of operated patients, their American Society of Anesthesiology (ASA) score of surgical risk, and the intrahospital morbidity and mortality. The number of treated patients significantly increased between these two periods (group I n = 49, group II n = 88, with 38 endovascular treatments; p < 0.001), without any changes in average age (70 vs. 72 years), percentage of men (93.7% vs. 95.5%), and mean AAA size (57.8 vs. 56 mm) between the two groups. ASA scores were significantly higher in group II (ASA III and IV, group I = 20.4% vs. group II = 55.7%; p < 0.0001), whereas the intrahospital mortality rate (4.1% vs. 3.4%) and the rate of major postoperative complications (16.3% vs. 11%) have remained stable. In group II, the median duration of hospitalization was significantly reduced (12 vs. 9 days, p < 0.001). In conclusion, in our center, following the AFSSAPS recommendations, the introduction of endovascular treatment has enabled us to electively treat a greater number of AAA patients with higher surgical risk, without aggravating the immediate postoperative results.

Primary vascular tumours are very rare. Most cases are leiomyosarcomas usually arising from large veins such as the inferior vena cava. Involvement of major veins in the limbs is uncommon and of small veins or tributaries extremely uncommon. We report a case of leiomyosarcoma originating from a tributary of the femoral vein in a 55-year-old woman.

External iliac artery (EIA) dissection and especially bilateral involvement is very rare. We report the case of a 49-year-old male intense bicyclist who had presented a dissection of the left EIA responsible for claudication. He underwent an iliofemoral vein graft bypass. The histopathologic examination showed a dissection of the EIA with an otherwise normal arterial wall. Two years after he resumed his sporting activity, a dissection of the right EIA occurred with the onset of claudication. The patient underwent a right iliofemoral vein graft bypass. Histopathologic examination showed the same lesions as on the left side. Bilateral involvement of EIA dissection is possible especially when the mechanism leading to dissection is persistent. An attentive follow-up is thus to consider.

Spinal cord ischemia is a major cause of complications after operative and endovascular treatment of descending thoracic or thoracoabdominal aortic aneurysms. Prior revascularization of the intercostal artery (IA) giving rise to the artery of Adamkiewicz (AA) using an artery of the thoracic wall would preserve circulation in the AA and allow obstruction of the IA at its origin. The purpose of this study was to determine the feasibility of revascularization of the IA giving rise to the AA using three thoracic wall arteries, i.e., lateral thoracic artery, thoracodorsal artery, and descending scapular artery. A total of 16 specimens from 8 cadavers (6 men and 2 women) were prepared. The length and diameter of the thoracic wall arteries were measured to ascertain the feasibility of revascularization of the IA giving rise to the AA. In addition, 12 preoperative spinal cord arteriograms were studied. We found that revascularization of the IA giving rise to the AA using thoracic wall arteries is feasible. This technique could be used to prevent spinal cord complications after treatment of descending thoracic or thoracoabdominal aortic aneurysms.
