Percutaneous gastrostomy and gastrojejunostomy with gastropexy: experience in 701 procedures.

Purpose: To evaluate the safety and efficacy of fluoroscopically directed percutaneous gastrostomy and gastrojejunostomy catheter placement with gastropexy.

Materials And Methods: The authors retrospectively reviewed the charts from 643 patients referred for fluoroscopically directed percutaneous gastrostomy or gastrojejunostomy during a 9 1/2-year period. In 615 patients, placement was attempted with use of three T-fastener gastropexy devices followed by percutaneous gastric puncture.

Percutaneous fenestration of a type I aortic dissection for relief of lower extremity ischemia.

A 36-year-old patient underwent successful percutaneous fenestration of a type I aortic dissection which had caused occlusion of the right common iliac artery and ischemia of the right lower extremity. The patient is currently (6 months post-fenestration) ambulating without any signs of vascular compromise. The technique may be useful in patients who are at high risk for surgical procedures.

Contrast-enhanced fat saturation magnetic resonance imaging for studying the pathophysiology of osteonecrosis of the hips.

We imaged 75 hips in 40 patients using fat saturation technique before and after intravenous injection of contrast (0.1 mmol/kg gadolinium diethylene triamine penta-acetic acid, Gd-DTPA). Eighteen hips in 11 patients were determined to be osteonecrotic, either by pathologic or clinical examination.
