Comparison of posterior and medial approaches for popliteal artery aneurysms.

Background: Long-term results of the posterior approach (PA) for the treatment of popliteal artery aneurysms are lacking in the literature. We reviewed our experience during a 13-year period in patients with popliteal artery aneurysms, comparing those treated through a PA with those operated on through a standard medial approach (MA).

Methods: Clinical data of all patients treated between February 1998 and October 2011 were retrospectively reviewed and outcomes analyzed.

Use of ultrasound debridement as an adjunctive tool for treating infected prosthetic vascular grafts in the lower extremities.

Background: To evaluate the role of an ultrasound (US) debridement system to treat conservatively patients with poor medical conditions who presented with infection of a prosthetic vascular graft in the lower extremities.

Methods: Data of all patients who underwent debridement of the grafts and/or surrounding tissue using an ultrasonic generator (Genera, Italia Medica, Milan, Italy) were recorded and retrospectively reviewed. Based on cultures, patients received specific antibiotic therapy.

Transcatheter thrombin embolization of a giant visceral artery aneurysm.

A 9.5-cm visceral artery aneurysm was found during a computed tomography (CT) scan performed for abdominal pain. Subsequent selective angiography showed the aneurysm arising from the second branch of the superior mesenteric artery (SMA).

Aneurysms of anomalous splenomesenteric trunk: clinical features and surgical management in two cases.

Aneurysms of the splenic artery that anomalously arise from a splenomesenteric trunk are a rarity. Aneurysmal disease of visceral arteries is found in only 0.2% of the general population.

Effectiveness and safety of the low-molecular-weight heparin CY 216 in the prevention of fatal pulmonary embolism and thromboembolic death in general surgery. A multicentre, double-blind, randomized, controlled clinical trial versus placebo (STEP). STEP Study Group.

Deep venous thrombosis is very frequent after general surgery, and its major complication, pulmonary embolism, is today the most frequent cause of postoperative death. The reduction of this cause of mortality is mainly based on its prevention rather than its therapy. This purpose was achieved by using physical and pharmacological means.
