It compromises the concerned arterial restoration and the functional and vital prognosis are called into question. Infectious complications are rare and represent 1 to 3% of the aortobifemoral prostheses. Usually, the postoperative vascular infections are classified into 3 grades according to the depth and extension of the septic process (I) Grade I concerns the cutaneous infections Grade II concerns the subcutaneous cellular tissue infections but not the restored arterial axis. Grade Ill concerns the infections of the prosthetic graft and/or – by extension, the arterial tree. This clinical classification is of great importance both practical and theoretical, from one hand because the patients presenting a grade I infection are generally cured after an adapted local treatment, and from the other hand, grade Ill infections pose difficult therapeutic, medical and surgical problems. At present, facing an infection of an aortobifemoral prosthesis, several therapeutic options are possible (2-4). These are

Symptoms were related to lower-limb ischaemia in all patients: 20 had critical ischaemia (three with severe acute ischaemia) and 31 claudication. One patient had renal failure with hypertension and stenosis of the renal arteries associated with an infrarenal aneurysm induced by Takayasu's disease. Indications for exposure of the supracoeliac aorta were Takayasu's disease in two patients and atheroma in 34 (implantation of the graft on the supracoeliac aorta because of the status of the aortic wall (calcification, inflammation) in 25 and because antegrade revascularization of the visceral arteries was required in nine). In 15 patients repeat aortic surgery was performed; four of these had undergone three previous aortic approaches. The postoperative mortality rate at 30 days was 2%. There were four (8%) acute postoperative graft oc...

Occlusion by embolization is an attractive alternative treatment. Between 1991 and 1995, we used Gianturco coils to embolize 17 hypogastric aneurysms in 14 patients. All patients were men with a mean age of 77 years. Ten patients had previously undergone aortic repair. Complete occlusion of the aneurysm was achieved in 16 cases but placement of an iliac stent was required in 1 case. Embolization failed in one case involving rupture of a large aneurysm. No complications were observed. Moderate buttock claudication was noted after bilateral embolization in three cases. Embolization of hypogastric artery aneurysm using coils resolves the long-term problems associated with surgical ligation. Extensive aneurysm of the origin to the bifurcation is the main indication for nonresective treatment but embolization can also be a useful alternative to open surgery for high-risk patients. Availability of stent grafts may extend the indication for endovascular treatment.

These operations represented 27.9% of 534 infrapopliteal bypasses performed during the same period. There were 92 males and 53 females. Mean age was 71.8 +/- 12.3 years. Signs and symptoms of critical ischemia were gangrene, ulceration, and isolated rest pain in 101 (69%), 23 (15.3%), and 25 (16.7%) cases, respectively. A composite (PTFE-saphenous vein) graft was used in 53 (35%) cases. In 96 prosthetic bypasses the distal anastomosis was performed using vein patch angioplasty in 65 (44%) cases and directly in 31 (21%). The in-hospital mortality rate was 3.3%. Patency, limb salvage, and patient survival rates were plotted according to the actuarial method and the curves obtained were compared using the log-rank test. Actuarial survival rates were 68% +/- 5% and 57% +/- 7% at 3 and 5 years, respectively. Primary patency and lower limb salvage rates were 41% +/- 5% and 68% +/- 6% at 3 years and 35% +/- 9% and 65% +/- 10% at 5 years, respectively. There was no statistically significant difference noted in primary patency rates at 3 years according to the type of bypass (composite or all-prosthetic: 36% vs. 44%), the type of distal anastomosis (direct or vein patch angioplasty: 43% vs. 45%), the site of distal anastomosis (upper or lower half of the leg: 38% vs. 46%), lateral or medial placement of the bypass (39% vs. 43%), or according to whether or not it was a repeat operation (40% vs. 44%). In conclusion, patency rates using infrapopliteal PTFE bypasses are low. Certain technical approaches, although they do not seem to improve patency, definitely increase the feasibility of bypass and in our opinion decrease the risk of early failure in unfavorable anatomic settings. The limb salvage rates following infrapopliteal PTFE and composite bypass are encouraging and justify the use of routine distal revascularization, even in the absence of autogenous vein graft.

Revascularizations of a visceral artery were done more often with a bypass graft (N = 61) than by endarterectomy (N = 6), reimplantation (N = 4) or endovascular technique (N = 3). Fifty patients had concomitant repair of the aorta and of the visceral artery, and ten had a staged repair, favored in-high risk patients and in cases of multiple visceral artery revascularizations. Four patients (7.5%) died (2 myocardial infarctions and 2 multisystem organ failure) and twelve (20%) had a non-fatal complication in the postoperative period. Survival was 91% at one year and 81% at 5 years. Our experience emphasizes the option of a staged approach in these high-risk patients, with the availability of extra-anatomic reconstruction, and t...

The aim of this study was to report the latest results of our series of 186 patients. One hundred and eighty-six patients (100 women and 86 men; mean age 74.5 +/- 13 years) were treated for pain during rest (31.5%), gangrene (58%), or ischemic ulcer (10.5%). The lesions were unilateral (n = 172) or bilateral (n = 14). Two hundred eighty-seven target lesions were treated: for stenosis (n = 168) or occlusion (n = 119): of superficial femoral artery (31.7%), popliteal artery (40%) or tibial arteries (28.3%). Technical success was achieved in 81% (15% amputations). The in-hospital mortality rate was 6.5%. The cumulative patency rate was 61 +/- 3% at 12 months, and 52 +/- 6% at 48 months. The limb salvage rate was 87 +/- 3% at 12 months and 82 +/- 4% at 48 months. Thirteen potential factors of patency were analyzed: the only predictive factors affecting patency were occlusio...

The results of endovascular therapies carried out over a 2-year period are analyzed. Twenty-three patients with critical ischemia (rest pain 13%, gangrene 87%) had 25 procedures on 29 leg arteries: percutaneous transluminal angioplasty in 17 arteries, rotational atherectomy in 10 arteries, laser recanalization (1 artery), directional atherectomy (1 artery). The hospital mortality rate was 4.3%. The cumulative patency and limb salvage rates were respectively 51% and 77% at 6 months, 34% and 71% at 12 months. Candidates for tibial-peroneal endovascular techniques should have a threatened limb, as long as the consequences of failed procedures on patients presenting with claudication can be disastrous, and as long as mid-term patency rates reported in the literature are not fair enough. In localized stenosis or short occlusions with adequate runoff, endovascular techniques a...

The results of nutrient flaps carried out over a 2-year period are analyzed. 12 patients had extensive gangrene compromising limb salvage (heel, dorsal or lateral aspect of foot or ankle at high risk of tendon or joint sepsis). Coverage of tissue loss was provided by a latissimus dorsi flap in 8 patients, a radial artery free flap in 1 patient, a supra-malleolar flap in 3 patients. The hospital mortality rate was 8.3%. The cumulative patency and limb salvage rates are respectively 58% and 67% at 6 months, 44% and 67% at 12 months. The challenge of inframalleolar reconstruction in patients presenting with critical ischemia is not always amenable to surgical revascularization to the foot, due to the lack of a suitable artery for bypass implantation or due to the lack of run-off, when arteriosclerosis of the plantar arch, or when distal embolisms are present.

However, some important differences include the vessels involved and the extent of the involvement. In the diabetic, the arteries most frequently involved are those below the knee. Arterial occlusions are bilateral, multisegmental, and involve unusual vessels such as the internal iliac artery, the deep femoral artery, the small branches and the collateral circulation. Arterial disease in the diabetic appears at a younger age, advances more rapidly, is more diffuse, and is almost as common in women as in men. Interaction of arterial disease, neuropathy and infection produces a wide away of clinical findings, including callus formation, foot ulcers, cellulitis, osteomyelitis and patchy areas of gangrene. Foot abscess and cellulitis require emergency debridement and drainage. Arterial reconstruction, including endovascular procedures, lessen the rate of amputation, allow partial foot amputation, and prevent from ...
