Comparative Study Clinical Trial
Comparison of precuffed and vein-cuffed expanded polytetrafluoroethylene grafts for infragenicular arterial reconstructions: a case-matched study.
Distal vein cuff interposition is often added to prosthetic infragenicular arterial reconstruction in an attempt to improve hemodynamics and patency rates. The purpose of this study was to compare the outcome of a precuffed expanded polytetrafluroethylene (ePTFE) graft with a vein-cuffed ePTFE graft for infragenicular bypass. We reviewed the clinical outcome of 77 patients with critical limb ischemia without available autologous vein conduits who underwent arterial reconstruction of 80 limbs to below-knee popliteal or tibioperoneal vessels using either ePTFE precuffed graft (precuffed group, 38 patients 40 limbs) or ePTFE vein-cuffed graft (vein-cuffed group, 39 patient, 40 limbs). ⋯ Overall patient survival at 1 and 3 years was 81 % and 57%, respectively. In this case-control study, results of precuffed ePTFE graft were similar to those obtained with vein-cuffed ePTFE grafts. The precuffed ePTFE graft is an adequate alternative conduit for infragenicular arterial reconstruction in patients with critical limb ischemia and no available autologous veins.

In-hospital outcomes associated with abdominal aortic aneurysm (AAA) repair are well described. However, little is known about post-discharge readmission rates, lengths of stay, associated mortality, and costs. We examined 206 consecutive patients who underwent AAA repair at two American hospitals between 1998 and 2000. ⋯ Overall, readmissions following AAA repair accounted for a cost >50% over and above the cost of the readmitted patients' index hospitalization. Hospital readmissions are common during the 6 months following AAA repair. Patients who are readmitted experience long lengths of stay and high mortality rates, and their care incurs high costs.

Case Reports
Acute thrombosis of inferior vena cava in a pregnant woman presenting with sciatica: a case report.
A 20-year-old pregnant woman was admitted to our department with symptoms of deep venous thrombosis in the left lower extremity and excessive lumbar pain. Low-molecular-weight heparin was administered. She recovered with this treatment, however, severe lumbar pain continued. ⋯ An urgent venous thrombectomy was performed. Sciatica and deep venous thrombosis resolved after the operation. Low-molecular-weight heparin was administered until the end of her pregnancy.
