Morphologic and hemodynamic findings at sonography before and after creation of a transjugular intrahepatic portosystemic shunt.

Objective: The purpose of this study was to describe the morphologic and hemodynamic findings in the hepatic vasculature before and immediately after creation of a transjugular intrahepatic portosystemic shunt.

Subjects And Methods: We used gray-scale, duplex, and color Doppler sonography to prospectively examine 25 patients before and after percutaneous placement of a stent to create a transjugular intrahepatic portosystemic shunt. Patency and direction of flow were determined in the stent and in the main, right, and left portal veins.

The importance of preoperative evaluation of the subclavian vein in dialysis access planning.

Adequate venous outflow is critical to the proper function of a vascular-access graft (arteriovenous fistula) used for chronic hemodialysis. Stenosis of the subclavian vein can significantly compromise this venous outflow. The development of such subclavian vein stenoses has been associated with the prior placement of temporary subclavian vein dialysis catheters.

Fluoroscopically guided percutaneous gastrostomy and gastroenterostomy: analysis of 158 consecutive cases.

We reviewed our experience with 158 consecutive patients who underwent either percutaneous gastrostomy or percutaneous gastroenterostomy during a 2-year period. The catheters used included Foley catheters (36), Cope-type gastric catheters (86), or Carey-Alzate-Coons gastrojejunostomy catheters (36). Gastrojejunostomy tubes were placed in patients with gastroesophageal reflux or aspiration, gastric atony, or partial gastric obstruction.

Structural identity of the TL antigen homologues derived from strain 2 and strain 13 guinea pigs.

Strain 2 and strain 13 guinea pig thymocytes have been shown to bear a molecule that by several criteria appears to be a homologue of the murine TL antigen. The existence of a TL polymorphism in the mouse system as evidenced by TL- strains and various TL phenotypes in TL+ strains prompted a study to determine if a similar polymorphism could be demonstrated in the guinea pig system. By using two-dimensional gel electrophoresis, the thymocytes of a third inbred strain, DHCBA, were shown to bear a TL antigen, and the TL antigens of strains 2 and DHCBA were shown to give identical patterns of spots.
