Hyperacute stroke patients and catheter thrombolysis therapy: correlation between computed tomography perfusion maps and final infarction.

Purpose: We investigated the correlation between abnormal perfusion areas by computed tomography perfusion (CTP) study of hyperacute stroke patients and the final infarction areas after intraarterial catheter thrombolysis.

Materials And Methods: CTP study using the box-modulation transfer function (box-MTF) method based on the deconvolution analysis method was performed in 22 hyperacute stroke patients. Ischemic lesions were immediately treated with catheter thrombolysis after CTP study.

[Ruptured true posterior communicating artery fusiform aneurysm: case report].

A 32-year-old female complained of a headache persisting for approximately one week. She was emergently brought to the hospital for sudden consciousness disorder early in the morning. Her neurological state was JCS 200 and WFNS Grade V.

[Natural history of unruptured cerebral aneurysms of the unoperated and observed cases].

Purpose: Natural history of unruptured cerebral aneurysms is still a matter of discussion. In this study, we investigated the prognosis of unruptured cerebral aneurysms of unoperated cases in a prospective design.

Methods: Between September, 1992 and December, 2001, we have encountered a 256 cases of unruptured cerebral aneurysms.

Importance of neuropsychological evaluation after surgery in patients with unruptured cerebral aneurysms.

Background: We evaluated neuropsychological function before and after surgery in patients with unruptured cerebral aneurysms.

Methods: Neuropsychological functions in 43 patients with unruptured cerebral aneurysms were evaluated before and 1 month after surgery. The neuropsychological examination included the Mini-Mental State examination, "Kana-hiroi" test, Kohs Block Design test, and Miyake's Memory test.
