Willis环动脉瘤破裂导致蛛网膜下腔出血(SAH)的病例行CT检查证实后即应行数字减影血管造影(DSA)或大片法血管造影以寻找动脉瘤,但这两种血管造影均较费时,且有一定的并发症与死亡率。为此作者前瞻性比较了CT血管造影(CTA)与DSA检出这类病例的Willis环动脉瘤的准确性。这种CTA是新近发展的,由计算机产生的三维血管造影成像技术。 共30例,男13例,女17例,19~76岁,平均49
Willis ring aneurysm rupture leading to subarachnoid hemorrhage (SAH) of the cases confirmed by CT examination should be underwent digital subtraction angiography (DSA) or bulk angiography to find aneurysms, but these two angiography were more Time-consuming, and have some complications and mortality. To this end prospectively compared CT angiography (CTA) and DSA detection of such cases of Willis ring aneurysm accuracy. This CTA is a newly developed, computer-generated, three-dimensional angiographic imaging technique. A total of 30 cases, 13 males and 17 females, aged 19 to 76, an average of 49
