Cerebral angiography in ischemic strokes.

Angiography remains a very important means of evaluation of ischemic strokes: it confirms the diagnosis showing the occluded artery. It eventually shows the anastomotic pathways for cerebral circulation and it often finds the causes of stroke, among which the most frequent are atherosclerosis (70%) and fibromuscular hyperplasia (10%). The safer way to perform angiography is the retrograde route. Indications for angiography must be discussed according to the type of stroke, its onset, and the arterial territory involved.

Venous infarctions.

Strokes of venous origin are relatively infrequent. They usually cause venous infarcts which can be observed in 2 main circumstances: cerebral thrombophlebitis or dural arteriovenous (AV) fistulae draining into cerebral veins. The authors study the CT and angiographic aspects of these venous infarcts and their evolution. Conventional angiography remains indispensable to confirm the diagnosis.

CT in cerebral thrombophlebitis.

The authors report their experience based upon 56 cases of CT in cerebral thrombophlebitis. Direct signs of occlusion of the veins are infrequent and interest lies in the abnormalities due to brain edema or venous infarct. It is fundamental to recognize these infarcts as their evolution is favorable under treatment. Angiography is necessary to confirm the diagnosis of thrombophlebitis which can be only suspected on CT findings.

[X-ray computed tomographic and angiographic aspects of venous angiomas of the brain. Apropos of 15 cases].

Clinical, computed tomography and angiography investigations were conducted in 15 cases of venous angioma of brain. These rare malformations (70 cases reported) are often asymptomatic or are revealed by the onset of epileptic seizures. The scanner produced images suggestive of a vascular malformation in 80% of cases. However, the purely venous character of the angioma and its exact site require confirmation supplied by angiography only, the lesion provoking characteristic images from the latter examination.

Computed tomography in primary lymphoma of the brain.

C.T. scans of 19 patients with histologically proved primary lymphoma of the brain were reviewed and divided into three groups: solitary tumors (58%), multifocal tumors (31,5%), diffuse involvement of the brain (10,5%). The C.T. differential diagnosis are manifold, including meningioma, glioma, metastases, progressive multifocal leukoencephalopathy. Arteriography is not specific, but, correlation with C.T. results may suggest the correct diagnosis and encourage biopsy. The radiosensitivity of primary lymphoma of the brain emphasizes, the importance of an early diagnosis.

[Results of embolization of spinal dural arteriovenous fistulas with perimedullary venous drainage].

From a group of 10 patients with arterio-venous meningeal fistulas of the dura-mater of the spinal cord, who where treated by embolization, the authors discuss and compare the results of this procedure to surgical management. This results, sometimes spectacular, are similar to surgical ones and sometimes better, essentially upon paresthesias and urinary troubles. They insist upon the interest of this management which appears often realizable in the same procedure than diagnostic angiography.

[Computed tomography in the diagnosis and surveillance of cerebrovascular accidents].

In cerebral hemorrhage, it provides an easy and early diagnosis, by demonstrating hyperdensity indicative of the presence of coagulated blood in the cerebral tissue. During the course of the illness, this hyperdensity progressively lessens, to disappear within a varying interval of time. The sequelae are seen as a cavity, the density of which is close to that of the CSF. In cerebral infarctions, the scan remains normal for the first few hours, and its only value at this stage is to eliminate cerebral hemorrhage before anticoagulants are prescribed. It is only after 24 to 48 hours that the fundamental sign is seen, that is hypodensity of the ischemic territory. This hypodensity may be accompanied by a mass effect and, above all, the uptake of contrast, which may be of great diagnostic importance, and the significance of which has been widely discussed. The course takes the form of the progressive development of the sequelary cystic appearance.

[An application of balloon probes. Preoperative electrophysiological test of the tolerance to temporal occlusion of the artery of cervical enlargement].

The authors report a case of testing of the temporary occlusion of origin of the radiculo-medullar artery for the cervical enlargement by balloon occlusion and both testing by clinical evaluation and evaluation of somesthesic evoked potentials and F wave. This testing allowed the surgical removal of a malignant tumor of the cervical vertebra including the vertebral artery and the origin of the radiculo-medullar artery for the cervical enlargement. About this case, they discuss possibilities and the theorical value of these pre-operative tests.

CT scan of dural arteriovenous fistulas.

CT was performed on ten cases of dural intracranial arteriovenous fistulas. There were 3 fistulas of the transverse sinus draining directly into the homolateral jugular vein; 2 fistulas of the sinus with distal occlusion of the sinus and back flow into the cortical veins (one was on the transverse sinus, the other on the sagittal sinus); 2 fistulas of the middle fossa; 3 fistulas with direct venous drainage into the cortical veins, one of these forming a tumor process in the posterior fossa. Osseous abnormalities were seen in only one case. Cerebral CT abnormalities, such as patchy or vermicular enhancement, were seen in all the cases with fistulas draining into the cerebral veins. Cerebral CT was normal in cases of fistulas of the sinus without back flow into the cerebral veins.
