The authors present a case of left ovarian metastasis from colon carcinoma causing sigmoid obstruction. On US and CT the ovarian mass appears as a primary malignant lesion. The lesion caused a regular sigmoid stenosis which mimicked, on barium enema, a volvulus and screened the primary lesion.
The absence of cerebral blood flow is the best criteria of cerebral death. Intravenous digital subtraction angiography (DSA) was performed in 110 patients with clinical signs of brain death. In 105 cases DSA, confirmed the stop of the intracranial circulation. In the other 5 cases, repeated examination a few hours later demonstrated arrested cerebral circulation. Organs transplantations were performed in 30 cases. DAS represents a relatively non invasive and quick to perform method to demonstrate brain death.
PURPOSE: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. METHODS: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. RESULTS: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated embolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). CONCLUSION: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis.
We report the case of a patient who suffered major trauma following a motorcycle accident that resulted in multiple fractures, bilateral hemopneumothorax, pulmonary contusions, and an isthmic rupture of the aorta with a pseudoaneurysm compressing the descending aorta. This compression was responsible for distal hypotension and low flow, leading to acute renal insufficiency and massive rhabdomyolysis. Due to the critical clinical status of the patient, which prevented any type of open thoracic surgery, endovascular treatment was performed. An initial stent-graft permitted alleviation of the compression and the re-establishment of normal hemodynamic conditions, but its low position did not allow sufficient coverage of the rupture. A second stent-graft permitted total exclusion of the pseudoaneurysm while preserving the patency of the left subclavian artery.
