Patency, limb salvage

and survival rates were assessed using Kaplan-Meier life-table analysis. Complete follow-up (range, 0.1-10.2 years; mean, 5.8 years) was obtained in 245 (95.7%) patients (66 were in the study group).

Results: The distal PA was chosen as the target vessel: (1) because the proximal, mid-PA was occluded or severely diseased and no other adequate inframalleolar or pedal branches Pitavastatin cost arteries were identified preoperatively (n = 30; 43.5%); (2) because an alternative inframalleolar target vessel was present but severely diseased (n = 9; 13%); (3) because of the length limitations of the available vein (n = 12; 17.4%; or (4) because of the presence of invasive infection or necrosis overlying the dorsalis pedis or posterior tibial arteries (n = 18; 26.1%). The study group was significantly younger than the control group (68 +/- 7 years vs 70 +/- 6 years, P = .039), and included significantly more patients with diabetes mellitus selleck chemicals llc (65.2% vs 50.2%, P = .033) and insulin dependence (52.2% vs 37.9%, P = .041), dialysis-dependent chronic kidney disease (5.8% vs 1.1%, P = .047), and history of smoking (75.3% vs 58.2%, P = .012). None of the patients died in the perioperative period.

Although the overall need for minor amputation was statistically higher in the PA group (78.2% vs 63.1%, P = .022), especially as concerns partial calcanectomy (8.7% vs; 2.1%, P = .026), the proportion of wounds completely healed during the follow-up and the mean time to wound healing were comparable in the two groups. Kaplan-Meier analysis showed comparable long-term patency, limb salvage, and survival rates in the two groups.

Conclusions: Revascularization

to the distal third of the PA can achieve much the same outcome in terms of patency and limb salvage rates, wound healing rate and timing, as when other inframalleolar or pedal branches are used. The skepticism surrounding use of the terminal PA as an outflow vessel appears to be unwarranted.”
“Objective: many The optimal treatment for hemodynamically significant infrainguinal vein bypass graft stenosis is not known. This study compares three options as first choice for the revision of failing infrainguinal vein grafts: cutting balloon angioplasty (CBA), standard percutaneous transluminal balloon angioplasty (PTA), and open surgical revision (OS).

Methods. Infrainguinal vein bypass graft lesions treated in a single institution during a 12-year period were evaluated. Of these, 161 lesions in 124 infrainguinal bypasses (101 patients) were treated with OS (n = 42), PTA (n = 57), or CBA (n = 62). The initial indication for the bypass in these patients was limb salvage in 73% and claudication in 27%. The primary outcome of interest was the development of vein graft occlusion or significant stenosis (>= 70%) as detected by surveillance duplex ultrasound scanning or arteriography some time after repair.
