    Notes: Abstract Background: The use of surgically implanted chemoinfusion pumps for the treatment of hepatic metastases from colorectal carcinoma can be complicated by intra- or extrahepatic misperfusion. This may result in suboptimal tumor exposure to the chemotherapeutic agent and injury to other gastrointestinal organs. Misperfusion can be managed by selective arterial transcatheter embolization. Methods: Between 1989 and 1996, 16 patients with liver metastases from colorectal carcinoma and with hepatic artery chemoinfusion pump misperfusion were treated using transcatheter coil embolization. Six female and 10 male patients (age range, 34–84 years; median, 51.5 years) were identified by retrospective review of the records of the Department of Interventional Radiology. After pump placement, abnormal liver perfusion scan or methylene blue endoscopy study results prompted angiography with coil embolization. After embolization, the imaging studies were repeated and patients were monitored in the Oncology Clinic. Results: Eight patients exhibited intrahepatic misperfusion (group 1) and eight extrahepatic misperfusion (group 2). Coil embolization was immediately successful in 100% of patients in group 1, with restoration of normal hepatic perfusion, and in 75% in group 2. There were no immediate procedure-related complications. Follow-up periods ranged from 1 to 23 months (median, 13.5 months). Embolization was unsuccessful for two patients (in group 2), who tolerated a modified chemotherapeutic regimen, with follow-up periods of 18.5 and 22 months. Conclusions: Transcatheter coil embolization is the therapy of choice for the management of hepatic artery chemoinfusion pump misperfusion. It is rapid, effective, and well tolerated by patients and obviates the need for additional surgical intervention.

    Description / Table of Contents: Résumé Le shunt intrahépatique portocave par voie transjugulaire (TIPS) est une méthode nouvelle intéressante pour le traitement des complications de la cirrhose alcoolique. Des progrès techniques récents permettent de l'utiliser dans le traitement de l'hémorragie par rupture des varices oesophagiennes. Cet article présente et discute les résultats des expériences récentes de placement du TIPS qui peut en principe être inséré chez pratiquement tout patient ayant une cirrhose. Le taux de complication est bas. Le TIPS est une méthode efficace pour contrôler l'hémorragie secondaire à la rupture des varices oesophagiennes et est surtout intéressant chez le patient en attente de transplantation hépatique. Le TIPS pourrait aussi avoir un rôle dans le traitement de l'ascite et d'autres pathologies associées à l'hypertension portale. Le problème essentiel est la perméabilité à long terme du shunt. Des solutions potentielles à ce problème sont abordées ici.
    Abstract: Resumen El shunt intrahepático transyugular (TIPS) constituye un novedoso método para el tratamiento de las complicaciones de la cirrosis. El avance tecnológico ha permitido una amplia aplicación del TIPS en el tratamiento del sangrado por várices esofágicas. El presente artículo presenta y discute los resultados de experiencias recientes con la implantación del TIPS. El TIPS puede ser exitosamente implantado en casi todos los pacientes, con una baja tasa de complicaciones. Significa una modalidad efectiva en el control de la hemorragia varicosa y es especialmente útil en el control del sangrado en pacientes que esperan transplante hepático. El problema de mayor significación en cuanto al uso del TIPS es su permeabilidad a largo plazo. Se presentan posibles soluciones para este problema de permeabilidad a largo plazo.
    Notes: Abstract Transjugular intrahepatic portosystemic shunt (TIPS) is an exciting new method for treating complications of cirrhosis. Technical advances have allowed TIPS to be widely applied in the treatment of variceal bleeding. This article presents and discusses the results of recent experiences in TIPS placement. TIPS can be successfully placed in almost all patients. The complication rate of the procedure is low. TIPS is an effective means of controlling variceal bleeding and is especially useful for controlling bleeding in patients awaiting liver transplantation. It may also have a role in the treatment of ascites and other conditions related to portal hypertension. The most important issue facing TIPS is the long-term patency of the shunt. Potential solutions to the problem of long-term shunt patency are discussed.

    Notes: Summary The CT appearance of eight cases of culture-positive spinal tuberculosis is reviewed. Three patients had single level vertebral involvement, while five others showed multilevel involvement. In seven of eight cases, paraspinal soft tissue involvement was seen. In two, the process caused neurologic symptoms by extending into the epidural space. In three patients the paraspinal extension was not only local, but spread along multiple levels. The CT appearance can be highly suggestive of TB in cases where the diagnosis has not been suspected. In cases where the diagnosis is suspected by plain films, CT can display unsuspected extension of the disease and be helpful in needle localization for aspiration.

    Percutaneous Management of Abscess and Fistula Following Pancreaticoduodenectomy (1999)
    Springer

    Notes: Abstract Purpose: To evaluate the efficacy of percutaneous drainage of fluid collections following pancreaticoduodenectomy (Whipple’s procedure). Methods: We performed a retrospective review of 19 patients referred to our service with fluid collections following pancreaticoduodenectomy. The presence of associated enteric or biliary fistulas, the route(s) of access for image-guided drainage, the incidence of positive bacterial cultures, and the duration and success of percutaneous management were recorded. Results: Fistulous communication to the jejunum in the region of the pancreatico-jejunal anastomosis was demonstrable in all 19 patients by gentle contrast injection into drainage tubes. Three patients had concurrent biliary fistulas. In 18 of 19 patients, fluid samples yielded positive bacterial cultures. Successful percutaneous evacuation of fluid was achieved in 17 of 19 patients (89%). The mean duration of drainage was 31 days. Conclusion: Percutaneous drainage of abscess following pancreaticoduodenectomy is effective in virtually all patients despite the coexistence of enteric and biliary fistulas.

    Talc Pleurodesis Through Small-Bore Percutaneous Tubes (1999)

    Notes: Abstract Pleurodesis using talc as the sclerosing agent is an effective procedure for preventing reaccumulation of malignant pleural effusions. Because of its thickness, the talc slurry is usually instilled through large bore (20–28 Fr), surgically placed thorocostomy tubes. However, these tubes often cause considerable patient discomfort. Herein we report a series of eight patients in whom the talc slurry was inserted through 10 and 12 Fr percutaneous chest tubes. Six of the eight patients (75%) had a successful pleurodesis without a reaccumulation of fluid. We conclude that this is an acceptable method for treating patients with malignant pleural effusions.
