Doppler sonography findings associated with transjugular intrahepatic portosystemic shunt malfunction.

Objective: Our purpose was to determine the overall accuracy of Doppler sonography and the accuracy of specific Doppler parameters associated with a compromised transjugular intrahepatic portosystemic shunt (TIPS).

Materials And Methods: For 43 patients who had undergone TIPS, 64 correlated sonogram-venogram paired examinations were analyzed. Sonographic parameters assessed included absolute velocities plus absolute and percentage changes in velocities measured in the main portal vein (MPV) and in several intrashunt locations (including peak and minimum velocity).

Nonsurgical management of gastric or duodenal perforation from a Wills-Oglesby-type gastrostomy tube.

Purpose: To describe the clinical and radiologic appearance of gastrointestinal perforation related to a Wills-Oglesby-type gastrostomy tube, as well as techniques for nonsurgical management.

Materials And Methods: Five patients with a previously placed 14-F modified Wills-Oglesby-type gastrostomy catheter experienced viscus perforation by the distal limb of the catheter during a 30-month period.

Results: The average interval between tube placement and perforation event was 4.

Surgeons' decision making in patients with chronic wrist pain: role of bilateral three-compartment wrist arthrography--prospective study.

Purpose: To determine if wrist arthrography changes surgeons' diagnoses and treatment plans for patients with chronic wrist pain.

Materials And Methods: Bilateral, three-compartment wrist arthrography was performed in 64 patients. Prospective questionnaires evaluated surgeons' diagnoses and management plans at three stages: before arthrography, after arthrography of the symptomatic wrist, and after arthrography of the asymptomatic wrist.
