Five patients with traumatic carotid-cavernous fistulae and two patients with internal carotid artery aneurysms inside the cavernous sinus are presented. A quantitative method was used for the evaluation of brain collateral circulation in the anterior and middle cerebral artery territories by using Tc-99m HMPAO SPECT before and during the Matas test. It affords a more reliable quantitative measurement of reduced activity than conventional carotid angiography during the Matas test. In this study, a reduction of radioactivity of less than 15% during the Matas test did not reveal any postoperative neurological deficit after a carotid artery trapping procedure. This noninvasive method seems to be useful to determine the appropriate surgical treatment.
本文报告了5例创伤性颈动脉海绵窦瘘患者和2例海绵窦内颈内动脉瘤患者。采用定量方法，通过在Matas试验前和试验期间使用锝-99m六甲基丙烯胺肟单光子发射计算机断层扫描（Tc-99m HMPAO SPECT）来评估大脑前动脉和中动脉区域的脑侧支循环。与Matas试验期间的传统颈动脉血管造影相比，它能对活动减少进行更可靠的定量测量。在本研究中，Matas试验期间放射性活性降低小于15%，在颈动脉阻断手术后未出现任何术后神经功能缺损。这种非侵入性方法似乎有助于确定合适的手术治疗方案。
