Comparative Study
Arm vein conduit vs prosthetic graft in infrainguinal revascularization for critical leg ischemia.
One-piece great saphenous vein (GSV) is the conduit of choice in infrainguinal revascularizations for critical limb ischemia (CLI). Unfortunately, adequate length of usable GSV is not always available. Despite inferior patency rates compared with GSV, prosthetic and arm vein conduits are generally considered usable. The purpose of this study was to compare the outcome of infrainguinal arm vein and prosthetic bypass. ⋯ Arm vein conduits, even when spliced, are superior to prosthetic grafts in terms of midterm assisted primary patency, secondary patency, and leg salvage in infrapopliteal bypasses for CLI.

Atherogenesis represents an active inflammatory process with leucocytes playing a major role. An elevated white blood cell count has been shown to be predictive of death in coronary artery disease patients. The aim of this study was to examine the predictive ability of neutrophil count and neutrophil/lymphocyte ratio for predicting survival in patients with critical lower limb ischemia (CLI). ⋯ This study suggests that an elevated NLR can identify a poor-risk subset of patients among those being treated for critical limb ischemia. This simple, inexpensive test may, therefore, add to risk stratification of these high-risk patients.

This study was conducted to identify risk factors for late mortality after thoracic endovascular aortic repair (TEVAR). ⋯ Preoperative leukocytosis, aneurysm diameter, and concurrent debranching independently predict late mortality irrespective of clinical presentation and may assist in risk stratification.

Patients who undergo surgery are at risk for venous thromboembolism (VTE), and a history of prior deep vein thrombosis (DVT) increases that risk. This study determined the incidence and risk factors for symptomatic perioperative VTE in patients with a prior diagnosis of DVT. ⋯ In patients with prior DVT, perioperative symptomatic recurrence is common and is associated with high-risk procedures. A longer time interval between a DVT episode and subsequent surgery may decrease the risk of recurrence, but large clinical trials are needed to confirm this. Further prospective evaluations are needed to identify and treat patients at greatest risk for recurrence.
