RESUMO
We report two patients with acutely thrombosed popliteal artery aneurysms that were successfully treated with a combination of thrombolytic therapy and placement of noncovered Wallstents.

Radiolabeled somatostatin analogs have shown uptake in a variety of tumors. These include carcinoid, Merkel cell carcinoma, pheochromocytoma, islet cell tumor, and other tumors with somatostatin receptors. Radiolabeled somatostatin analog imaging with Indium-111-DTPA-pentetreotide permits whole body imaging, providing a new safe and effective means for detection of primary tumors and metastatic foci in neoplasms with somatostatin receptors. This imaging modality is helpful in screening the entire body as well as evaluating questionable foci of disease identified by conventional imaging modalities. This case report demonstrates the utility of computed tomography (CT) and radiolabeled somatostatin imaging as complementary modalities in the workup of a patient with metastatic carcinoid tumor.

Seventy-seven transjugular liver biopsies were performed with a coaxial, spring-loaded, 18-gauge cutting needle, the Biopty gun (Bard Biopsy System, Covington, GA, USA) on consecutive patients between July 1993 and February 1995. Fifty men and 27 women were included in the study; the mean age was 45 years (range 15-69 years). The average number of punctures per patient was 5.2, with a range of 2-9, yielding an average of 4.8 samples per patient (range 1-7). The length of the samples varied from 10 to 22 mm with a constant diameter of 1 mm. The mean time required to complete the procedure was 48 min (43-52 min). Histological diagnoses were obtained in 74 of 77 patients (96%), with non-diagnostic specimens attributed to excessive fragmentation (3 cases). Complications occurred in 10 patients (puncture site hematoma, carotid artery puncture, abdominal pain, vasovagal reaction, hepatic capsule perforation, and hemobilia). The latter two complications were self-limited. In our experience this transjugular hepatic biopsy method is promising for performing biopsies in patients with chronic liver disease, due to its high success rate and low morbidity rate.
