Percutaneous biliary internal decompression in a patient with simultaneous malignant biliary and duodenal obstruction and surgically modified anatomy.

Australas Radiol 2007 Dec;51 Suppl:B334-6

Department of Radiology, Guy's and St. Thomas' NHS Foundation Trust, London, UK.

Simultaneous involvement and obstruction of the common bile duct and the duodenum presents a difficult and challenging problem to the surgeon, the endoscopist and the interventional radiologist. In the case report we present here, the patient had had duodenal and biliary obstruction secondary to hepatic flexure adenocarcinoma and presented with recurrent obstructive jaundice. As the surgically modified anatomy precluded all conventional endoscopic and percutaneous approaches, it was necessary to use an improvised method of achieving biliary decompression. Read More

Iatrogenic stenosis following suture-mediated closure device.

Australas Radiol 2007 Dec;51 Suppl:B319-23

Radiology Department, Alfred Hospital, Prahan, Victoria, Australia.

The use of percutaneous closure devices post arterial punctures has been introduced to reduce time to haemostasis, reduce haemorrhage, improve patient comfort and reduce time to ambulation. Their increased use has been a result of larger access sites for more complicated procedures, periprocedural anticoagulation and concomitant use of anti-platelet therapy. Although complication rates are not increased with their use as compared with mechanical compression, complications may be more severe and are an important consideration in their use. Read More

Intramural haematoma of the thoracic aorta: rupture and endoluminal exclusion.

Australas Radiol 2007 Dec;51 Suppl:B313-5

ICU Department, Christchurch Hospital, Christchurch, New Zealand.

Intramural haematoma is an increasingly recognized condition, characterized by an acute haemorrhage into the aortic wall without the creation of a pseudolumen. We present a case that was diagnosed by non-contrast CT scanning, which showed a hitherto undescribed contained rupture into the mediastinum, but no haemothorax. This complicated intramural haematoma was then successfully treated with endoluminal exclusion, which was performed during frank rupture of the thoracic aorta into the left hemithorax which occurred just before the commencement of the endoluminal exclusion.

Multiple hepatic hemangiomas with fluid-fluid levels.

Australas Radiol 2007 Dec;51 Suppl:B310-2

Department of Diagnostic Radiology, Guro Hospital of Korea University, Guro2-Dong, Guro-Ku, Seoul, Korea.

Hepatic haemangiomas with fluid-fluid levels are known to be rare with only five cases reported in the English literature. According to the previous reports, the presence of fluid-fluid level could attribute to the separation of blood cells and serous fluid because of the extremely slow flow in cavernous haemangioma of the liver. We describe the imaging features of multiple hepatic haemangiomas with fluid-fluid levels, which was pathologically proven with ultrasonography guided biopsy. Read More
