The Use of the Angiosome Concept for Treating Infrapopliteal Critical Limb Ischemia through Interventional Therapy and Determining the Clinical Significance of Collateral Vessels.

Background: The purpose of this study was to evaluate the clinical significance of the involvement of collateral vessels in interventional therapy based on the angiosome concept for infrapopliteal critical limb ischemia (CLI).

Methods: We enrolled 486 patients with unilateral infrapopliteal CLI (Rutherford Stage 5 or 6) treated at 2 hospitals from January 2005 to December 2014. Using the angiosome concept, the patients were categorized into 3 groups: the direct revascularization (DR) group, the indirect revascularization through collaterals (IR-tc) group, and the indirect revascularization without collaterals (IR-wc) group.

Incidence and risk factors of early deep venous thrombosis after varicose vein surgery with routine use of a tourniquet.

Introduction: The incidence of early deep venous thrombosis (DVT) following varicose vein surgery (traditional open stripping) with routine use of a tourniquet remains unknown.

Materials And Methods: A retrospective analysis of all patients who underwent varicose vein surgery with a tourniquet in the authors' unit between 1 January 2012 and 30 November 2013 was undertaken. Cases of postoperative DVT were identified from the unit database, and re-assessments conducted 1, 3 and 6 months after the initial diagnosis were recorded from the outpatient department.
