Treatment of inferior vena cava obstruction in hemodialysis patients using Wallstents: early and intermediate results.

Objective: The purpose of this study was to evaluate the efficacy of Wallstents in treating inferior vena cava obstruction in hemodialysis patients.

Conclusion: For the short and intermediate term, percutaneous placement of inferior vena cava Wallstents, followed by balloon angioplasty, is a safe and valuable technique for preserving the often limited central venous access in hemodialysis patients. To maintain patency, recurrent stenosis within the Wallstent can be treated with additional angioplasty.

Placement of retrograde nephroureteral stents through ileal conduits.

Objective: Our objective was to evaluate retrograde nephroureteral stent placement in patients with ileal conduits.

Conclusion: In patients with ureteral complications after cystectomy and ileal diversion, retrograde nephroureteral stent placement should be the treatment of choice to reduce patient morbidity, increase patient comfort, and facilitate stent care.

Are routine chest radiographs necessary after image-guided placement of internal jugular central venous access devices?

Objective: The purpose of this study was to determine the value and cost of obtaining routine chest radiographs after image-guided placement of internal jugular central venous catheters.

Materials And Methods: We reviewed the records of 424 patients in whom 572 internal jugular catheters were placed by sonographic and fluoroscopic guidance over a 2-year period. Inspiratory and expiratory chest radiographs obtained immediately after each procedure were also reviewed.

Radiologically guided placement of pull-type gastrostomy tubes.

Purpose: To evaluate percutaneous placement of pull-type gastrostomy tubes that has traditionally necessitated endoscopic guidance.

Materials And Methods: From September 1995 through March 1997, 63 pull-type gastrostomy tubes were placed in 64 patients. Retrograde catheterization of the esophagus was performed through the stomach.

Wallstent deployment to salvage dialysis graft thrombolysis complicated by venous rupture: early and intermediate results.

Objective: The feasibility of deploying Wallstents to treat venous rupture occurring during dialysis graft thrombolysis was determined.

Subjects And Methods: Between June 24, 1994, and February 19, 1997, 23 patients with venous rupture attributed to balloon angioplasty during dialysis graft thrombolysis were treated by Wallstent deployment across the area of rupture. Twenty-one ruptures occurred in peripheral veins and two occurred in central veins.

Radiologic placement of subcutaneous infusion chest ports for long-term central venous access.

Objective: The technical success and complications associated with radiologic placement of subcutaneous implantable chest ports for long-term central venous access were evaluated.

Materials And Methods: Between May 1, 1996, and December 31, 1996, 80 chest ports were placed in 80 consecutive patients using the right internal jugular vein as the preferred access route. All procedures occurred in interventional radiology suites with patients receiving conscious sedation.

Angioplasty treatment of portal vein stenosis in children with segmental liver transplants: mid-term results.

Objective: Percutaneous venoplasty has showed excellent technical success and excellent early results in treating portal vein stenoses in children with reduced-size liver transplants. We review the mid-term results in 22 children in whom portal venoplasty was attempted.

Subjects And Methods: During 27 months, percutaneous transhepatic portal venoplasty was attempted in 22 children with portal vein stenoses.

Extrahepatic portal vein stenosis in recipients of living-donor allografts: Doppler sonography.

Objective: The aim of this study was to describe the appearances obtained and the pitfalls involved with the use of Doppler sonography for detecting portal vein stenoses after surgery in 198 recipients of pediatric reduced-size transplants.

Subjects And Methods: We analyzed sonographic and Doppler studies after surgery for 167 children (average, 2.5 years old) who were recipients of 198 left lobe or left lateral segment liver segments (79 living-donor allografts and 119 cadaveric grafts).

Portal vein stenosis in children with segmental liver transplants: treatment with percutaneous transhepatic venoplasty.

Objective: We reviewed the early results of percutaneous portal venoplasty as a method of treating portal vein stenosis in 11 children with reduced-size liver transplants.

Subjects And Methods: Percutaneous transhepatic portal venoplasty was attempted in 11 children with portal vein stenoses over a period of 9 months. The venoplasty was performed by direct puncture of an intrahepatic portal vein followed by balloon angioplasty of the stenotic segment.

Skin diseases in tourists to Hawaii.

This is the first report of travellers' skin diseases from the Hawaiian archipelago. The diagnoses of all tourists who presented to a dermatology practice on Kauai, Hawaii, were recorded over six years. The cutaneous disorders tabulated in visitors differed significantly from those observed in the local population.

Scabies epidemiology, Kauai, Hawaii, 1981-1985.

The demography of scabies was studied in the sole dermatology practice on the island of Kauai, Hawaii, over a 50-month period. Scabies was observed far more frequently in whites and Hawaiians than in Japanese and Filipinos. Within the white ethnic group, scabies was most frequently diagnosed in persons between 15 and 44 years old, while in Hawaiians, the disease was most common in the 0-14-year age group.
