Surgically transplanted ovary simulating a hepatic metastasis.

Background: Surgical procedures may alter normal anatomy, confounding the interpretation of cross-sectional imaging studies. This problem is greater if neither a relevant history nor previous comparison studies are available.

Case Outline: In a 29-year-old woman submitted to radical hysterectomy for cervical carcinoma, one ovary was surgically repositioned into the right paracolic gutter out of the radiation field.

Removal of a trapped endoscopic catheter from the gallbladder via percutaneous transhepatic cholecystostomy: technical innovation.

Background: Percutaneous cholecystostomy is used for a variety of clinical problems.

Methods: Percutaneous cholecystostomy was utilized in a novel setting to resolve a problematic endoscopic situation.

Observations: Percutaneous cholecystostomy permitted successful removal of a broken and trapped endoscopic biliary catheter, in addition to helping treat cholecystitis.

Delayed presentation of traumatic aortocaval fistula: a report of two cases and a review of the associated compensatory hemodynamic and structural changes.

Chronic aortocaval fistula (ACF) is a rare complication of gunshot wounds to the abdomen. Herein we report two cases of traumatic ACF: one asymptomatic and the other presenting with congestive heart failure (CHF) 20 and 30 years, respectively, after their initial injury. The recent onset of CHF, the presence of a continuous abdominal bruit, and, in the second patient, a history of penetrating trauma suggested the diagnosis of ACF.

Kondo effect of molecular complexes at surfaces: ligand control of the local spin coupling.

The spin state of single magnetic atoms and molecules at surfaces is of fundamental interest and may play an important role in future atomic-scale technologies. We demonstrate the ability to tune the coupling between the spin of individual cobalt adatoms with their surroundings by controlled attachment of molecular ligands. The strength of the coupling is determined via the Kondo resonance by low-temperature scanning tunneling spectroscopy.

Interventional radiology strategies in the treatment of pseudomyxoma peritonei.

Purpose: To describe percutaneous maneuvers to treat the unusual entity symptomatic pseudomyxoma peritonei (PMP).

Methods: Four patients with PMP were treated by interventional radiology techniques that included large catheters (20-30 Fr) alone (n = 3), multiple catheters (n = 4), and dextran sulfate as a catalytic agent through smaller catheters (n = 1). The causes of the PMP were tumors in the ovary (2 patients), appendix (1 patient), and colon (1 patient).
