Hemodynamics in the anterior part of the circle of Willis in patients with intracranial aneurysms: a study of cerebral angiography.

Cerebral angiography revealed that hypoplasia of the A1 portion of the anterior cerebral artery is more frequent in patients with aneurysms of the anterior communicating artery than in those with aneurysms of other intracranial arteries. As for the hypoplasia of the A1, the angiographic findings corresponded to the surgical findings in 86.9% of all the patients. In patients with anterior communicating artery aneurysms, the incidence of hypoplasia of the A1 portion was about 3 times higher on the right side than on the left side.

[Complications following cerebral angiography. Report on 4181 cerebral angiographies].

Complications of 4181 cerebral angiographies performed from 1973 to 1978 in 2365 patients were analysed. In 13,6% of the patients temporary complications could be observed. In 3,1% temporary neurologic-psychiatric complications occurred, most of them in patients of younger age and in the presence of diffuse cerebrovasuclar disease. There was a permanent damage in 0,21%.

[Improvement of MRA and 3D-CTA does away with the need for cerebral angiography in many cerebral aneurysm operations].

The purpose of this investigation was to study the indication of cerebral angiography in recent operations for cerebral aneurysms. Cerebral angiography has been used for diagnoses and operations for cerebral aneurysms, but, as the diagnostic procedures such as magnetic resonance angiography (MRA) and three dimensional computed tomographic angiography (3D-CTA) have made remarkable progress, cerebral angiography is not always an indispensable diagnostic tool for cerebral aneurysm operations. One hundred nineteen patients (including 40 patients with ruptured aneurysms) out of 165 patients (including 61 patients with ruptured aneurysms) were diagnosed and operated on following MRA and 3D-CTA. All of these cases of cerebral aneurysms were operated uneventfully without the need for cerebral angiography. We concluded that cerebral angiography is not needed for diagnoses and operations of small common cerebral aneurysms such as middle cerebral artery aneurysms, internal carotid artery-posterior communicating artery aneurysms and anterior communicating artery aneurysms. Cerebral angiography is necessary only in relatively large aneurysms to confirm the dynamic circulation of the cerebral blood flow before operation.

[Complications in cerebral angiography. A study of 6698 cerebral angiographies].

The complications of 6,698 cerebral angiographies performed from 1979 to 1985 in 2,503 patients were analysed. In 5.24% of the patients (1.95% of the angiopathies) temporary complications could be observed. Temporary neurologic-psychiatric complications occurred in 1.96% of the patients (0.73% of the angiographies), most of them in middle-aged patients and in the presence in the presence of diffuse cerebrovascular disease. In 0.12% of the patients (0.05% of the angiographies) a permanent damage was recorded.

Complications following transfemoral cerebral angiography for cerebral ischemia. Report of 159 angiograms and correlation with surgical risk.

One hundred fifty-nine transfemoral cerebral angiograms for patients with carotid stenosis who subsequently underwent carotid endarterectomy were reviewed. No patient with an asymptomatic carotid bruit developed cerebrovascular complications during angiography. Patients with transient ischemic attacks (TIAs) had a 4.5% incidence of complications. Patients with stroke in evolution had a complication rate of 7.7%. Patients with completed strokes had no angiographic complications. No complication lasted more than 1 hour; all occurred during angiography or immediately afterwards. Stroke in progress has too high a surgical and angiographic risk to warrant study. Transient ischemic attacks have an acceptable morbidity both surgically and angiographically.

ECG changes during cerebral angiography. An analysis of 334 patients--942 cerebral angiographies.

We have analyzed HR changes greater than 20% among 334 patients and 942 cerebral angiographies. A tachycardial effect was seen in 14.9% of patients, while a bradycardial effect was seen in 7.1% including two patients having cardiac standstill (0.5%). These two patients were examined without atropine premedication after subarachnoid hemorrhage. Patients under 19 years of age, unpremedicated with atropine sulfate and suffering from subarachnoid hemorrhage secondary to ruptured aneurysm or arteriovenous malformation showed a significantly high incidence of bradycardia. On the other hand, patients with the neoplastic disease and having an initial sinus bradycardia showed a significantly high incidence of a tachycardial effect.

Cerebral angiography in acute cerebral infarction.

Cerebral angiography in the acute phase of clinically diagnosed stroke syndromes was evaluated in a prospective study of 104 consecutive patients over an eight month period at the Massachusetts General Hospital to determine the diagnostic yield. Of 68 patients subsequently documented to have retinal or cerebral hemispheric infarction, 63 (92.6%) had angiographic demonstration of occlusive lesions which appeared to correlate with the clinical deficit. These results are discordant with prior angiographic reports, 2,17,18,20 suggesting that delayed carotid artery angiography fails to show occlusive lesions (embolic) which may be shown acutely.

Platelet activation following cerebral angiography.

Following cerebral angiography, the level of beta thromboglobulin rose in five of seven patients (P = less than 0.05). This would indicate that there had been generalised platelet activation. In view of the morbidity of cerebral angiography it is proposed that a trial of prophylactic anti-thrombotic therapy be instituted.
