False aneurysm of a hepatic artery branch complicating intrahepatic islet transplantation.

Islet transplantation, an innovative treatment strategy for type 1 diabetes mellitus, is a relatively safe procedure, with less morbidity than pancreas transplantation. Vascular injuries have not been reported to date. We report a percutaneous transhepatic intraportal islet transplant infusion that was followed by bleeding from a false aneurysm of an intrahepatic branch of the hepatic artery. The bleeding was controlled by selective embolization. Despite the complication and its treatment, the patient gained insulin independence, which was sustained for 285 days. She is currently on a small dose of insulin with good glycemic control.

Selective ovarian vein sampling to localize a Leydig cell tumor.

OBJECTIVE: To describe a patient with recent onset of rapidly progressive virilization who was diagnosed with an androgen-secreting tumor of the left ovary, localized by selective ovarian vein catheterization and hormonal sampling (SOVHS). DESIGN: Case report. SETTING: Tertiary community-based medical center. PATIENT(S): A 32-year-old woman presenting with progressive virilization over a period of 4 months was found to have a Leydig cell tumor of the left ovary. INTERVENTION(S): Transvaginal ultrasound of the pelvis, followed by contrast-enhanced computerized tomography of the abdomen and the pelvis. Selective ovarian vein sampling was performed to localize the tumor. Laparoscopic left salpingo-oophorectomy and washings were also performed. MAIN OUTCOME MEASURE(S): Initial serum total T levels were 1,505 ng/dL, and the free serum T levels were 234 ng/dL. After SOVHS, the total serum T levels in the left ovarian vein is reported to be 20,967 ng/dL, and in the right ovarian vein, they were reported to be 1,351 ng/dL. Three months after laparoscopic left oophorectomy, the serum total T levels were 11 ng/dL. Institutional review board approval was obtained. RESULT(S): Patient's ovarian tumor removed laparoscopically was reported to be a Leydig cell tumor. Rapid decreases in free and total T followed tumor removal. CONCLUSION(S): Selective ovarian vein catheterization and hormonal sampling is an effective diagnostic modality that can help localize small ovarian tumors.
