Embolotherapy for massive upper gastrointestinal haemorrhage secondary to metastatic renal cell carcinoma: report of three cases.

Three cases are reported in which angiographic embolisation therapy was effective in arresting upper gastrointestinal bleeding secondary to metastatic hypernephroma. Each patient had histologically confirmed disseminated renal cell carcinoma and presented with recurrent haematemeses with a successful outcome following palliative embolisation therapy.

Color Doppler sonography in the evaluation of palpable breast masses.

Objective: A prospective study was performed to determine the value of high-resolution color Doppler sonography in the evaluation of palpable solid breast masses.

Subjects And Methods: One hundred thirty-one consecutive breast lesions were characterized as benign, malignant, or indeterminate on the basis of their sonographic appearance. The number of blood vessels was estimated, the Doppler spectrum for each vessel was characterized, and the maximum velocity was recorded.

Accuracy of computed tomography during arterial portography in the segmental localization of liver tumours.

The ability of computed tomography during arterial portography (CTAP) to identify and segmentally locate 20 hepatic tumours was prospectively assessed in 7 patients undergoing hepatic resection. All eight lesions greater than 2.5 cm in diameter were detected, but only two out of four and two out of eight of those measuring 1-2.

Radiologically controlled balloon dilatation of rectal strictures.

Rectal stricture is a well recognized complication following anterior resection. It is traditionally managed with metal dilators or resection. This paper describes the use of balloon dilatation for benign anastomotic rectal strictures.

Failure of ultrasound to detect extra-pancreatic abscesses in severe acute pancreatitis.

The development of intra-abdominal abscesses in patients with severe acute pancreatitis can be associated with a mortality as high as 100%. The clinical findings in these patients may be non specific and therefore imaging is essential. Computed tomography (CT) is the imaging modality of choice.
