Abstract

To assess the efficacy and safety of a vacuum-assisted thrombectomy (VAT) catheter system for treating patients with acute limb ischemia (ALI). A retrospective study evaluated VAT systems (Penumbra, Alameda, California) in a consecutive series of 30 patients with ALI. ALI was defined as clinical symptoms within 2 weeks of presentation. The primary endpoint was improvement in blood flow across a lesion by improvement in Thrombolysis in Myocardial Infarction (TIMI) score that was adapted to peripheral arteries. Concomitant balloon angioplasty or stent placement in addition to VAT was considered a complementary treatment. Additional thrombectomy treatments, such as thrombolysis and mechanical thrombectomy, were considered technical failures. Target lesions were grouped anatomically into above-the-knee (ATK) or below-the-knee (BTK) lesions. In 30 patients, 33 lesions (ATK, n = 13; BTK, n = 20) were treated. No complications were attributed to the VAT systems. The primary endpoint was obtained in 24/33 (72.7%) lesions (BTK, 17/20 [85.0%]; ATK, 7/13 [53.9%]; P = .050 by χ(2) test). TIMI scores were similar at baseline but differed after VAT between the ATK and BTK groups (P < .025 by t test). ATK lesions required more concomitant ang...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
