| Abstract | 「I. はじめに」脳室心房短絡術や脳室腹腔短絡術は種々の水頭症患者の治療としてさかんに実施されており, 最近は正常圧水頭症の治療法として脚光をあびている. 短絡装置は多種多様のものが市販されているが, その代表的なRickham-Holterの装置とPudenzの装置をFig. 1に図示した. 脳室短絡系路の通過障害は(1)心房あるいは腹腔端での閉塞(末梢側閉塞), (2)脳室端での閉塞(中枢側閉塞), (3)弁の機能障害の3つに大きく分類できる. 閉塞部位により手術が若干異なるため, 客観的で正確な診断法が望まれていた. 脳槽スキャンは術前, 術後の脳脊髄液動態を検査するのに優れているが, 脳室短絡系路の閉塞部位の診断は不可能である. |

| Abstract | [Summary] We examined ventricular shunt patency and site of obstruction. A small volume (0.05 ml) of 99mTcO4- (50μCi to 100 μCi) was injected into the reservoir with a 26G gauge needle. Scintiphoto was taken after a few minutes at supine position with polaloid camera. When shunt was patent, the scintiphoto showed reservoir and distal tube. When the scintiphoto did not show the distal tube, the second scintiphoto was taken at sitting position. In some patients, only the second scintiphoto showed distal tube. In obstructed case, the second scintiphoto did not show distal tube. In obstructed case, phisiologic saline (0.1 ml) was reinjected into the reservoir and flushed the 99mTcO4-from it. At the same time, we examined the possibility of CSF withdrawal from the reservoir. In Rick-ham-Holter system, we examined the function of Holter valve by digital depression. These results were shown on table 1. We can detect the obstructed site correctly with this combined examination. |
