Eastern Association for the Surgery of Trauma practice management guidelines for hemorrhage in pelvic fracture--update and systematic review.

Background: Hemorrhage from pelvic fracture is common in victims of blunt traumatic injury. In 2001, the Eastern Association for the Surgery of Trauma (EAST) published practice management guidelines for the management of hemorrhage in pelvic trauma. Since that time there have been new practice patterns and larger experiences with older techniques.

Inferior vena cava filters in trauma patients: efficacy, morbidity, and retrievability.

Background: Thromboembolic events are potentially devastating sources of morbidity in trauma patients. With increasing experience and the introduction of retrievable devices, there has been a renewed interest in inferior vena cava (IVC) filters in trauma patients.

Methods: The records for consecutive trauma patients undergoing IVC filter placement during the years 2001 to 2005 were reviewed, and clinical, demographic, and procedural data were evaluated for associations with thromboembolic events and device complications.

CT angiography of renal artery anatomy for evaluating embolic protection devices.

Purpose: To determine which commercially available embolic protection devices are suitable for use in renal arteries.

Material And Methods: A retrospective study was conducted of 97 patients who underwent three-dimensional computed tomographic (CT) angiography with either 16- or 64-detector row helical CT of the renal arteries for the evaluation of renal artery stenosis. Nine anatomic measurements were obtained of the renal artery from each reformatted CT angiogram.

Adventitial remodeling with increased matrix metalloproteinase-2 activity in a porcine arteriovenous polytetrafluoroethylene grafts.

Background: We hypothesized the source of early proliferating cells contributing to venous stenosis formation in a porcine hemodialysis grafts is the adventitia and media, and migration of these cells is greatest within the first two weeks following graft placement, resulting in increased matrix metalloproteinase-2 (MMP-2) activity.

Methods: Polytetrafluoroethylene grafts from the iliac artery to the ipsilateral iliac vein were placed in 23 pigs and 5-Bromo-2'-deoxyuridine (BrdU) was given at 24 and 48 hours after surgery to assess cell proliferation and migration. Angiography and magnetic resonance angiography was performed.

Renal artery stent placement: complications at a single tertiary care center.

Purpose: To describe complications after renal artery stent placement in patients with atherosclerotic renal artery stenosis (RAS) at a single tertiary care center and analyze the risk factors for these complications.

Materials And Methods: Medical records and angiograms of 171 patients who underwent a total of 179 consecutive percutaneous transluminal renal artery stent placement (PTRS) procedures for atherosclerotic RAS were retrospectively reviewed. Data on patient comorbidities, procedure indication, lesion location, serum creatinine level, and procedure-related complications were analyzed.

Infectious and ischemic complications from percutaneous closure devices used after vascular access.

The introduction of percutaneous closure devices (PCDs) to seal arteriotomy sites following percutaneous vascular access (PVA) can lead to greater complications than those with manual compression. The aim of this study was to compare complications and outcome between patients requiring surgery after receiving a PCD and those undergoing standard manual compression. This retrospective study evaluated 56 patients (mean age, 63 years) requiring surgical intervention from January 1, 1998 to April 30, 2002, following complications of PVA.
