It can be life-threatening as abdominopelvic organs, specifically those in the retroperitoneal space, can bleed profusely. APT is divided into blunt and penetrating types.

Purpose: Aim of this study is to present our initial experience with the use of the retrograde popliteal artery access in patients with certain anatomic lesions.

Methods: Between September 2008 and September 2010, 24 patients underwent a transpopliteal retrograde subintimal recanalization. Instead of its usage when antegrade recanalization failed, the "facedown" technique was preferred as a first choice in patients with common femoral artery stenosis or occlusion, proximal lesions of the superficial femoral artery (SFA) with no stump, severe obesity, tandem iliac, and SFA lesions.

Introduction: Recent studies have reported a risk reduction in the progression of benign breast disease to breast carcinoma through COX-2 pathways.

Case Presentation: We present a case of severe epithelial hyperplasia in a 47-year-old woman with increased breast density submitted to scintimammography by the proliferation-imaging tracer Technetium-99m-labelled pentavalent dimercaptosuccinic acid, before and after an oral ibuprofen treatment for 4 weeks. The radiotracer uptake after ibuprofen intake was significantly reduced, both visually and by semi-quantitative analysis, based on a calculation of lesion-to-background ratios.
