Pituitary apoplexy causing internal carotid artery occlusion--case report.

A 50-year-old man presented with pituitary apoplexy resulting in internal carotid artery occlusion manifesting as sudden onset of severe headache, right ptosis, and left hemiparesis, associated with visual impairment. Computed tomography showed a nodular mass, located in the sellar and suprasellar regions with early signs of acute cerebral ischemia. Magnetic resonance (MR) imaging indicated that the mass compressed the bilateral cavernous sinuses, resulting in obliteration of the cavernous portion of the right internal carotid artery.

Semiquantitative dynamic computed tomography to predict response to anti-platelet therapy in acute cerebral infarction.

We investigated whether dynamic computed tomography (CT) in patients with acute cerebral infarction could identify patients likely to respond to anti-platelet therapy. Seventy patients underwent semiquantitative dynamic CT within 6 h as well as cerebral angiography. All then received anti-platelet therapy with a thromboxane A2 synthetase inhibitor.

Short-term arteriographic and clinical outcome after cerebral angioplasty and stenting for intracranial vertebrobasilar and carotid atherosclerotic occlusive disease.

Background And Purpose: The safe performance of percutaneous transluminal cerebral angioplasty for intracranial atherosclerotic lesions requires that the risk of complications, such as acute occlusion or symptomatic dissection, and restenosis be reduced. Our purpose was to assess the effectiveness, safety, and short-term arteriographic and clinical outcome of cerebral angioplasty and stenting (CAS) for intracranial vertebrobasilar and distal internal carotid atherosclerotic occlusive lesions.

Methods: Between March 1998 and November 1998, 10 patients with 12 intracranial atherosclerotic lesions of the vertebrobasilar artery and the distal internal carotid artery underwent treatment with flexible balloon-expandable coronary stents.

Stenting treatment for intra- and extra-cranial atherosclerotic diseases.

The purpose of this study was to investigate the effect, safety and short-term outcome of stenting treatment for extra- and intra-cranial atherosclerotic diseases. Forty-one patients underwent stenting treatment using coronary and biliary stents. Eleven patients had tubular or diffuse high-grade stenoses not amenable to standard balloon angioplasty involving intra-cranial arteries, while in thirty, extra-cranial arteries were involved.

[The usefulness of dynamic computed tomography scanning in predicting the outcome of acute stroke patients].

The aim of this study was to investigate whether brain dynamic computed tomography (CT) is useful in predicting clinical outcome. Thirty patients suffering from cerebral ischemia in the territory of the middle cerebral artery (MCA) underwent dynamic CT scanning within 6 hours of stroke onset. Regions of interest (ROIs) were placed in the bilateral MCA territories and three parameters, peak value (PV), time to peak (TP), and PV divided by TP, were calculated from time-density curves (TDCs) on ROIs.
