Percutaneous repair of aortic aneurysms: a prospective study of suture-mediated closure devices.

PURPOSE: To evaluate prospectively the safety and efficacy of totally percutaneous placement of abdominal and thoracic aortic endografts using the Prostar XL suture-mediated closure system. METHODS: From January 2002 to January 2005, we attempted to insert percutaneously all bifurcated abdominal aortic and thoracic endografts. Consecutive patients (25 men, four women), with mean age 74.9 years (range 44-84), underwent endovascular repair for 20 abdominal aortic aneurysms (AAA) and nine thoracic aortic aneurysms (repeat operation in one case). Endografts used included 21 Zenith (Cook), eight Talent (Medtronic), one AneuRx (Medtronic). For the technique, two Prostar XL 8F were used to close 22-24F access sites and one Prostar XL 10F to close 16F access sites. RESULTS: Procedural success was achieved in 21/29 (72.4%) patients and in 39/47 access sites (83%). Closure of 22-24F access sites with tandem 8F Prostar devices was successful in 23/29 (79.3%) cases. Closure of 16F access sites with 10F Prostar device was successful in 16/18 (88.8%) cases. There were seven peri-procedural failures requiring surgery to repair the femoral artery in three cases. Four access complications healed without intervention. Overall 25/29 (86.2%) patients had complete percutaneous repair. No late complications were detected during follow-up (median 17.5 months). CONCLUSIONS: Percutaneous treatment of patients with AAA and thoracic aneurysms is feasible in most cases, with a very low risk of access-related complication, providing that the operator has sufficient practical experience of this technique.

When can revascularization be limited to the profunda femoris alone?

Dealing with lower limbs arteriopathies with combined aorto iliac and superficial femoral occlusive diease and when ischemia leads to operation should an extension bypass to the popliteal or tibial artery be associated every time it is possible? The authors have investigated the results of revascularizing operation above the profunda femoris on 35 limbs (27 patients). On 19 limbs only, has the revascularization been sufficient to cure the distal ischemia. On the other 16 limbs, a second operation was necessary 7 times an extension bypass to the popliteal or tibial artery, once an above knee amputation, twic a below knee amputation. From the comparison of these results with the degree of ischemia and the arteriographic aspect of the profunda femoris, the author's conclusion is that revascularization must extent below the profunda femoris unless the profunda is in good condition and there is no rest ischemia.     

Closure of carotid bifurcation endarterectomy using a polyurethane patch. A multicentre prospective study with 252 patients

BACKGROUND: In order to evaluate the results of carotid endarterectomy with closure using a polyurethane patch, a multicentre prospective study of 252 patients (263 interventions) undergoing this operation was performed between November 1996 and August 2001. METHODS: One hundred and seventy-one men and 81 women with a mean age of 70 years were studied. Fifty-five percent of the patients had neurological symptoms. The degree of carotid stenosis evaluated using the European carotid surgery trialist's collaborative group (ECST) criteria was greater than or equal to 70% in 95% of cases. RESULTS: The combined mortality-morbidity operation rate (CMMR) was 2% (1 death from cerebrovascular haemorrhage on Day 3, 1 non-regressive cerebrovascular accident (CVA), 3 regressive CVAs). The patients had follow-up clinical examinations and Doppler ultrasound scans for 2 years. Fifteen patients died during follow-up, 8 of these patients died from heart-related causes and 2 patients died from CVA. Four patients presented with CVAs ipsilateral or contralateral to the endarterectomy. Two false aseptic aneurysms and 1 false septic aneurysm required further surgery. Three asymptomatic carotid occlusions occurred during follow-up. The rate of restenosis greater than 50% was 1.2% at 6 months, 2.3% at 1 year and 5.3% at 2 years. CONCLUSIONS: These results confirm the value of po-lyurethane patch closure of carotid endarterectomy.
