The radiological and angiographic changes resulting from abdominal aortic trauma after blunt injuries are described in four patients. These include intimal damage as well as perforation.
The indications for and diagnostic value of visceral angiography in 30 cases of acute gastrointestinal bleeding are discussed. In one third of these emergency angiograms the etiology of the bleeding could not be demonstrated. In two thirds of the cases the source of bleeding was successfully localized. In half the positive angiograms the bleeding site was shown directly in the form of extravasation of contrast, while in the remaining half pathological findings were demonstrated without evidence of contrast media extravasation.
Closed injury to the thoracic aorta at the isthmus occurred after street accidents in eight persons (five males, three females, aged 17-55 years). The lesions ranged from isolated intimal rupture to complete loss of continuity of the aorta. Radiological diagnosis or thoracic surgical exploration took place in five patients within 48 hours of the accident, while in the remaining three--alle with a false aneurysm of the thoracic aorta-the time elapsed before accurate diagnosis ranged from three months to seven years. Five patients were successfully operated upon. It is stressed that successful surgical intervention depends on early and accurate radiological diagnosis (chest X-ray and, if necessary, aortogram).
Traumatic damage to the rotator cuff was diagnosed in 13 patients by clinical, electromyographic and arthrographic studies. The main features were failure to rotate, elevate or abduct the affected shoulder joint. Eight patients also had peripheral nerve lesions: axillary nerve lesion was present in five, partial brachial plexus lesion in three.
Two cases of a cord trans-section syndrome resulting from contrast damage to the spinal medulla were observed amongst 4,000 abdominal angiograms (0.05%). The anatomical basis, causes and means for avoiding this serious complication of abdominal catheter angiography, are discussed.
Three angiographic observations showing partial mesenteric vascularisation of renal tumours were made. Problems in diagnosis and therapy arising from this are discussed.
The value of renal angiography is assessed on the basis of findings in 40 cases of renal tuberculosis. The differential diagnosis from unspecific infective renal disease and from hypovascular renal tumors is discussed.
