[Stroke therapy. Combined therapy of hyperbaric oxygenation and extra- intracranial arterial bypass operation].

Neurological and EEG-analytical follow-up examinations in 73 patients with carotid artery occlusion were done for a period of 3 1/2 years after completed stroke. All patients were treated by hyperbaric oxygenation (HO), in 38 cases additionally bypass surgery was performed. Our findings indicate that chronic ischemic alterations of the brain can be improved by HO-therapy and additional recovery can take place after subsequent extra-intracranial arterial bypass operation.

Superficial temporal-middle cerebral artery anastomosis in Moyamoya disease.

A 41-year-old Libyan woman with Moyamoya disease and persisting post-stroke neurological deficits was treated by a superficial temporal-middle cerebral artery (STA-MCA) anastomosis. The postoperative angiograms revealed that the STA was rapidly irrigating the territory of the middle cerebral artery including those regions that had been filled preoperatively via different networks of collaterals. Furthermore prompt venous drainage was seen to occur postoperatively. Following surgery EEG analyses revealed considerable increase in the electrical brain activity, and neurological examinations showed reversal of neurological deficits. The dependence of the postoperative neurological improvement on the increased cerebral blood supply through the new collateral channel could be demonstrated by the effect of temporary occlusion of the STA on the electrical brain activity.

Superficial temproal-middle cerebral artery anastomosis for internal carotid occlusion.

The observations presented are based on 11 patients who had suffered from stroke caused by internal carotid occlusion. In all cases an anastomosis between the superficial temporal artery (STA) and a cortical temporal branch of the middle cerebral artery (MCA) was done. This resulted in a considerable additional blood supply from the external carotid to the affected middle cerebral circulation. The extent of the territory of the MCA irrigated by the STA depends upon the different anatomical configurations of the MCA. There was a considerable improvement in neurological status even in the chronic post-stroke stage. A topographical correlation between the postoperative angiographically identified increase of rCBF and the recovery or considerable improvement of neurological functions was not ascertained.

The use of hyperbaric oxygenation in the treatment of spinal cord lesions.

In 13 patients with compressive spinal cord lesions we performed a trial of treatment with hyperbaric oxygen (HO). This therapy was postoperatively administered when neurological deficit persisted. In order to assess the effect of each individual HO session (given daily at an inspiratory oxygen pressure (PO2) of 1.5 atmospheres absolute for 40 min) as well as of the entire HO therapy (consisting of 10-15 single sessions in each case) neurological and electromyographical follow-up examinations were regularly performed. In 6 of the 13 patients we found a marked improvement, particularly in motor functions. The other patients only showed little change in neurological status. Arterial and cerebrospinal fluid (CSF) PO2 were concurrently measured in 8 patients during HO sessions. The values of both showed a considerable increase. The rise in CSF PO2 may be regarded as indicative for an improved oxygenation of the spinal cord tissue during HO treatment. On the basis of these findings we may assume that repetitive HO treatment can be helpful in the management of compressive spinal cord lesions.

[Dissecting aneurysm with damage to median nerve].

A case of iatrogenic dissecting aneurysm in the cubital region causing secondary damage to the median nerve is reported. This aneurysm was caused by an attempted venipuncture, in what can be considered a minor procedure. Such a severe complication is very remarkable, for it has not been observed so far even in much more potentially hazardous procedures as, for instance, in the numerous arterial punctures in the cubital region being daily performed for retrograde angiography of the cerebral vessels. In this case the reduced blood coagulation is discussed as a causing factor of this unusual complication.
