The radiographic appearance and clinical significance of gastric varices in the absence of esophageal varices and secondary to splenic vein occlusion were studied. Eighteen patients were evaluated through medical records, angiography, and barium studies of the stomach and esophagus. The presence of splenic vein occlusion was determined by arteriography in… (More)
Immunosuppressive therapy is necessary in the treatment and prevention of rejection in renal transplant recipients. Unfortunately, these patients may become intolerant to this therapy when it is complicated by hypersplenism with leukopenia and/or thrombocytopenia. The therapy must then be either decreased or stopped, thus preventing adequate treatment or… (More)
Ventricular shunts were evaluated by a shuntographic technique using metrizamide for the contrast material and delayed spot films and computed tomography (CT) to evaluate shunt function. Thirty hydrocephalic patients were studied who had clinical presentations of shunt malfunction. Fifty-two shuntograms were obtained; most demonstrated the cause of shunt… (More)
Lidocaine (60 mg/100 ml) was added to contrast medium (120 ml of Conray-60) in an attempt to decrease pain associated with leg venography in 100 patients. No side effects were seen, and there was a marked reduction in pain as reported by four different examiners in two separate hospital populations.
Displacement of the nasogastric tube to the right as a new sign in the diagnosis of an acute traumatic rupture of the thoracic aorta was reevaluated by statistical analysis in 28 patients (seven patients with a traumatic aortic aneurysm and 21 patients with normal aortas). This new sign was compared with the commonly used chest radiographic findings in 46… (More)
Blunt injury to the neck can cause hemorrhage and pseudoaneurysm formation. A 76-year-old patient with severe blunt injury to the anterior neck was found to have entrapment of the left vertebral artery at C2-C3. Arch aortography 3 weeks postinjury revealed a large aneurysm at the injury site. The mass was surgically reduced, followed by ligation of the… (More)
The detection of underlying arterial injury is a major problem in the management of penetrating trauma. Arteriovenous fistula and false aneurysm are late sequelae of unrepaired injuries. The diagnostic accuracy of arteriography in clinically occult injury has not been defined. One hundred and seventy-seven patients with 183 penetrating extremity wounds… (More)
Renal venography was performed in 21 hypertensive patients, all of whom had the classical appearance of fibromuscular dysplasia of the renal arteries. None showed any evidence of fibromuscular dysplasia of the renal veins.
