中文摘要 | 內頸動脈頸段血管瘤之病例甚為少見,其發生之病因包括有先天性的、外傷造成的、動脈硬化或感染菌病所造成的。臨床上可能為無症狀或一些非特殊性症狀,其他常見明顯症狀為口咽部或頸部博動性腫塊,臨床上常見之嚴重病況表現為血管瘤內之血栓因血流衝擊漂流至顱內血管形成栓子造成梗塞型中風,或是當血管瘤過大且血管瘤壁薄弱,造成血管瘤破裂形成鼻出血,此種情況具有潛在的致命性危險。其治療方式從早期外科血管繞道手術,發展至血管內支架合併白金線圈栓塞術,至現今大部份病例皆以包膜支架置放術所取代。且其術前血管瘤大小,開口及起源動脈之評估,亦可利用多層切面電腦斷層(multi-slices computed tomography, MSCT)所取代。於此我們提出一內頸動脈假性血管瘤病例,從臨床症狀、診斷及術前評估,並以包膜支架成功治療且提出相關討論。 |
英文摘要 | Aneurysms of cervical internal carotid arteries are uncommon. The most likely etiological cause of aneurysm involving the cervical internal carotid artery is referred to in the literature as congenital or developmental, followed by traumatic, arteriosclerosis and mycotic pseudoaneurysms. The aneurysms can be asymptomatic or may have a long silent period. Often the symptoms are vague or nonspecific. Other most common clinical symptom is a pulsatile mass in the oropharynx or neck according to the location of the aneurysms. The most frequent and clinically serious presentation of carotid aneurysm is related to distal embolism from aneurysmal sac resulting in ischemic stroke, which occurred in over 60% of cases. The major life threatening cause of carotid aneurysm is ruptured aneurysm with external hemorrhage. Currently, endovascular treatment of covered stent grafts in aneurysms of cervical internal carotid artery can be a safe and effective alternative to conventional surgery and other endovascular techniques. And multi-slices CT angiography is a non-invasive and useful tool for pre-stenting evaluation in aneurysmal size, orifice and parent artery, and also used in post-stenting follow up. |
