内容記述タイプ Abstract
内容記述 Intravenous digital subtraction angiography (IV DSA) was performed on 3,146 patients in the period between February 1989 and March 1994. They were retrospectively investigated to detect unruptured cerebral aneurysms (An) to determine its incidence and the usefulness of this test to be used for screening purposes. These patients had slight or mild neurological problems but had no history indicative of cerebral Ans. From them, 2,730 (86.8%) IV DSA studies were of excellent image quality. Among these, 161 suggested the presence of unruptured Ans. For these, 142 received cerebral angiography by intra-arterial digital subtraction angiography (IA DSA). Forty-six were confirmed to have Ans (1.9% incidence) and 33 were subjected to surgery. The remaining 96 patients had no An (67.6% false positive). The smallest one detected on IV DSA was 2 mm in size. There were 10 Ans which escaped detection by IV DSA but were confirmed by IA DSA or during surgery (17.4% false negative). All of them were smaller than 3 mm in size. We believe unruptured cerebral Ans over 5 mm in diameter, which pose a greater risk of rupture, can be sufficiently detected by IV DSA. For this procedure, a short catheter with a large caliber was used for pressure injection of the contrast medium via a femoral vein. This method proved to be very adequate in obtaining clear images of IV DSA. In the same period, we performed 4,609 IV DSA for various neurological problems including the above cases. In 4,057 of them (88.0%), the pictures were of excellent image quality. In 57 cases (1.2%), there were slight complications. Our study suggests that IV DSA is a useful means of detecting unruptured cerebral Ans for screening purposes.
