[Flow abnormalities in the carotid due to trauma and their differential diagnosis (author's transl)].

Amongest nine cases of internal carotid artery thrombosis following blunt trauma, six showed a typical acute contrast termination several cm. beyond the carotid bifurcation. In the other cases, one was taken with an unusual projection, one had a high occlusion beyong the origin of the ophthalmic artery and the third showed a stenosis due to a mural thrombosis. Perforating carotid injuries should be examined angiographically because of the danger of late complications. Two functional occlusions were observed following acute vascular angulation. This type of occlusion is contrasted with the convex vascular margin in the internal carotid artery seen in atherosclerotic, embolic or "spontaneous" carotid occlusion.

[Pre-operative renal artery occlusion with a balloon catheter (author's transl)].

Renal artery occlusion with a balloon catheter introduced by the transfemoral route makes nephrectomy for tumour much easier. Advantages of vascular occlusion are a bloodless field and shrinking of the kidney with a significant reduction of blood loss during the operation. In addition, operative displacement of tumour thrombus is largely avoided.

[The urethrogram in children with neurogenic bladder dysfunction (author's transl)].

Various types of neurogenic bladder dysfunction in children show characteristic changes on micturating cystograms. The reflex bladder shows a short area of narrowing of the urethra at the pelvic floor; the autonomous bladder, during voiding by straining or Credé shows an elongated and deformed urethra, which is narrowed at the pelvic floor and which, because of the low position of the bladder, is angled. Both spastic and paretic pelvic floor in association with neurogenically determined abnormalities of bladder emptying may result in functional obstruction of the urethra. This, like any other stenosis, leads to morphological changes, first in the lower, but subsequently in the upper urinary tract. Children with neurogenic bladder dysfunction occasionally have micturating cystograms which resemble the appearances of urethral valves. The occurrence of so-called occult neurogenic bladders is mentioned and the difficulties in diagnosis associated with this condition are stressed.

[The relation of electroencephalographic foci to vasospasms in patients with subarachnoid haemorrhage (author's transl)].

During a period of five years 74 patients with acute subarachnoid haemorrhage were controlled by angiography and EEG. 19 patients demonstrated angiographically proved intracranial aneurysms, seven intracerebral haematomas, three arteriovenous abnormalities. 25 patients had vasospasms. 34 patients showed foci in the EEG. Focal neurological abnormalities were in 43 patients. A correlation was established between EEG focus and vasospasm, focus and intracerebral haematoma. Further a relationship between focus and focal neurological abnormalities was detected. There was no correlation between EEG focus and aneurysm. It was claimed, that some foci in the EEG could be the result of persistent vasospasms.

[Wide-spread haemangioma racemosum of the mediastinum associated with paresis of the diaphragm; a finding to be considered in the differential diagnosis of the arteriovenous aneurysm of the thorax (author's transl)].

The paper reports on a 5 year old boy showing a sprawling haemangioma racemosum of the right side of the mediastinum. The vascular tumor is fed by a tortuous A. thoracica interna dextra and numerous arterial vessels arising from the right subclavian artery and from the aorta including the right coronary artery and branches from the abdominal aorta. The child presents also paresis of the right diaphragm probably secondary to the pressure of the pulsatile tumore along the course of the phrenic nerve. After ligation of three major feeding arteries the continuous murmur disappeared and fatigability and anorexia became less. Apart from this report a review of the literature on vascular malformations of the arterio-venous fistula type within the thorax sums up the most important features of these vascular anomalies: haemodynamics, localisation, clinical signs, therapy, natural history, therapy and etiology.

[Rare late complications following thorotrast arteriographs (author's transl)].

Hematemesis in a thorotrastosis patient with severe liver dystrophy led to a tentative diagnosis of portal hypertension. The possibility of portal hypertension was eliminated via angiography. The cause of the hematoemesis was multiple bleeding stomach ulcers. In spite of severe damage to the liver parenchyma, portal hypertension with thorotrastosis does not usually occur. This has been confirmed in the literature and by histologic investigations. In second thorotrastosis patient, the cause of pain and swelling was a sterile abscess formation in the area of the thorotrastoma.

[An unusual cerebral arteriovenous malformation (author's transl)].

A rare, extensive arterio-venous fistula with cardiac enlargement was found in an infant. Numerous branches from the internal and external carotid artery were disposed in a stellate manner to form a large central vessel, probably corresponding to the inferior sagittal sinus. The brain was grossly abnormal. The embryology, clinical features and diagnoses are discussed.
