Role of prophylactic temporary inferior vena cava filters placed at the ICU bedside under intravascular ultrasound guidance in patients with multiple trauma.

Objective: Patients with multiple trauma often have injuries that preclude the use of anticoagulation therapy or sequential compression device prophylaxis. Temporary inferior vena cava (IVC) filters (IVCFs) offer protection against pulmonary embolism during the early immediate injury and perioperative period, when risk is highest, while averting potential long-term sequelae of permanent IVCFs. The objective of this study was to evaluate the efficacy of prophylactic, temporary IVCF placement at the intensive care unit bedside under real-time intravascular ultrasound (IVUS) guidance in patients with multiple trauma.

Real-time intravascular ultrasound-guided placement of a removable inferior vena cava filter.

Background: Reports have demonstrated the benefit of prophylactic inferior vena cava filter (IVCF) placement to prevent pulmonary embolism. This series evaluates the potential for the bedside placement of a removable IVCF under "real-time" intravascular ultrasound (IVUS) guidance.

Methods: Twenty trauma patients underwent intensive care unit placement of a removable IVCF with IVUS guidance.

Prevention of intimal hyperplasia; Initial results with low-dose beta-radiation applied by an external vascular polymer wrap.

Objective: Endovascular brachytherapy, delivered by a variety of catheter-based devices, has proven clinically effective for the inhibition of neointimal hyperplasia (NIH) after coronary and peripheral balloon/stent angioplasty. No platform, however, has been developed to deliver low-dose radiation in concert with vascular surgical operations. The purpose of this study was to evaluate the vascular response following balloon injury to the rabbit carotid artery, with and without topical low-dose 45Ca, applied by an external vascular "wrap".

Remote superficial femoral artery endarterectomy and distal aSpire stenting: multicenter medium-term results.

Objective: The purpose of this study was to examine the results of remote superficial femoral artery endarterectomy (RSFAE) in conjunction with distal aSpire stenting.

Methods: RSFAE is a minimally invasive procedure performed through a limited groin incision. Forty patients were included in the study.

Cellular remodeling of depopulated bovine ureter used as an arteriovenous graft in the canine model.

Background: One of the greatest challenges in hemodialysis access surgery is improving the durability of prosthetic grafts caused by structural deterioration. The depopulated bovine ureter SynerGraft (SG) (CryoLife, Inc) is a tissue-engineered vascular graft processed to remove the xenograft cells while maintaining an unfixed connective tissue matrix capable of autologous cell repopulation by the recipient.

Study Design: Nineteen 6-mm diameter bovine ureter SG conduits were implanted in 12 dogs as arteriovenous grafts between the carotid artery and jugular vein (n = 11) or between the femoral artery and vein (n = 8).

External heating of stents by radio waves: pilot studies in rabbit aorta.

Purpose: This experiment was designed to assess the feasibility of radio frequency energy delivered by a prototype radio frequency generator inductive heating device (REVAX) positioned external to the body, for transient heating of stents after arterial implant.

Methods And Materials: Twenty-one New Zealand White rabbits underwent stenting of their infrarenal aorta. Nine rabbits were stented and immediately placed in the REVAX for external stent heating with internal temperature probes in place.

Retrohepatic vena cava and hepatic vein injuries: a simplified experimental methods of treatment by balloon shunt.

Background: Fecal contamination from colon injury has been thought to be the most significant factor for the development of surgical site infection (SSI) after trauma. However, there are increasing data to suggest that other factors may play a role in the development of postinjury infection in patients after colon injury. The purpose of this study was to determine the impact of gastric wounding on the development of SSI and nonsurgical site infection (NSSI) in patients with colon injury.
