Access to the superficial femoral artery in the presence of a "hostile groin": a prospective study.
Lower limb angioplasty is commonly performed via antegrade common femoral artery (CFA) puncture, followed by selective superficial femoral artery (SFA) catheterization. Arterial access can be complicated by a "hostile groin" (scarring, obesity, or previous failed CFA puncture). We prospectively investigated color duplex ultrasound (CDU)-guided SFA access for radiological interventions. ⋯ The CDU-guided SFA puncture technique was both more effective than CDU-guided CFA access in patients with scarred groins, obesity, or failed CFA punctures and safer, with reduced screen times, radiation doses, and complications.

Endovascular repair of traumatic rupture of the thoracic aorta: single-center experience.
Traumatic rupture of the thoracic aorta secondary to blunt chest trauma is a life-threatening emergency and a common cause of death, usually following violent collisions. The objective of this retrospective report was to evaluate the efficacy of endovascular treatment of thoracic aortic disruptions with a single commercially available stent-graft. ⋯ This is the first time the EndoFit graft has been utilized in the treatment of thoracic aortic disruptions secondary to chest trauma. The repair of such pathologies is technically feasible and early follow-up results are promising.
