Angiographic manifestations in postrecanalized cerebral infarction.

In 14 stroke patients showing angiographic recanalization of the occluded internal carotid artery or middle cerebral arterial axis, the postrecanalized angiograms demonstrated several findings that have been considered to be generally rare in cerebral infarction. These findings principally consisted of narrowing of arterial caliber in six cases (43 percent), mass effect in eight cases (57 percent) and capillary blush in five cases (36 percent).

[Adenoid cystic carcinoma extended to Gasserian ganglion-report of two cases (author's transl)].

Adenoid cystic carcinoma is an uncommon tumor, especially in cases of its extension into the cranial cavity. Two cases of this tumor involving Gasserian ganglion were reported. The first case was a 47 year old female who developed paresis of the right side fifth cranial nerve. The plain skull X-ray of the axial view demonstrated enlargement of the right sided foramen ovale. The tumor was removed exploring the middle fossa extradurally, however its extention through the foramen ovale remained behind. A small induration was found at the base of the oral cavity postoperatively, and the biopsy revealed characteristic findings of adenoid cystic carcinoma histologically. Radiation therapy was followed by considerable clinical improvement.

Pattern difference of reversed ophthalmic blood flow between occlusion and stenosis of the internal carotid artery. An ultrasonic Doppler study.

Reversed ophthalmic blood flow in the occlusions (33 patients) and stenoses (11 patients) of the internal carotid artery (ICA) was examined using the ultrasonic Doppler technique. The Doppler shift frequencies of the blood flow signal were analyzed to obtain their sound spectrogram. In stenosis of the ICA, "presystolic notch" was more frequently observed and "d/S" value (S, d; maximum blood flow velocity at systolic and diastolic) was smaller than in occlusion. These two characteristics of stenosis distinguish it from occlusion with 89% accuracy although this method is applicable only for the patients with reversed ophthalmic blood flow.

Transient neurological deficits due to embolic occlusion and immediate reopening of the cerebral arteries.

The authors present two cases of transient occlusion of the major cerebral arteries which occurred during transfemoral catheterization of the carotid artery. Right hemiplegia and aphasia developed suddenly in both cases, and disappeared completely within 14 hours in one case and 25 minutes in the other. On the angiograms performed at the moment of onset of the symptoms, the site of the occlusion was the left internal carotid artery in one case and the left middle cerebral artery in the other. Angiograms which were repeated soon after clinical improvement revealed complete dissolution of the occluding emboli. These cases present direct radiographic evidence that embolic occlusion of a major cerebral artery and its disappearance is the mechanism of the transient manifestation of the neurological deficits associated with cerebrovascular catheterization.
