Vascular injury associated with extremity trauma: initial diagnosis and management.

Vascular injury associated with extremity trauma occurs in <1% of patients with long bone fracture, although vascular injury may be seen in up to 16% of patients with knee dislocation. In the absence of obvious signs of vascular compromise, limb-threatening injuries are easily missed, with potentially devastating consequences. A thorough vascular assessment is essential; an arterial pressure index <0.

Accuracy of duplex sonography scans after renal artery stenting.

Purpose: Reports of duplex sonography scan criteria for recurrent renal arterial (RA) stenosis after endoluminal stenting have suggested that criteria for native arteries may overestimate recurrent disease. This retrospective report examines the utility of renal duplex sonography (RDS) scans to define the presence of significant (ie, ≥ 60%) renovascular disease (RVD) after percutaneous angioplasty and endoluminal stenting (PTAS).

Methods: Demographic, duplex, and angiographic data were reviewed and compared.

Open repair of aortic aneurysms involving the renal vessels.

This retrospective review examines the open surgical repair of intact juxtarenal (JRAAs) and suprarenal (SRAAs) aortic aneurysms to estimate effects on survival and renal function. Patients undergoing open repair of JRAA and SRAA were identified. Preoperative medical comorbidities and perioperative and late outcomes were recorded.
