【摘要】：目的:探討基于320排容積CT灌注檢查的動態(tài)血管成像(CTPa)對顱內(nèi)動靜脈分流性疾病的臨床應(yīng)用價值。方法:回顧性分析26例經(jīng)CTPa檢查診斷為顱內(nèi)動靜脈分流性疾病患者的影像學(xué)資料。以時間為序列進(jìn)行多時相動態(tài)觀察,記錄病灶的部位、大小及血管構(gòu)筑特點(diǎn)。其中17例患者行DSA檢查,CTPa與DSA結(jié)果對照,分析兩者診斷一致性。結(jié)果:26例患者包括動靜脈畸形18例、動靜脈瘺8例。CTPa能夠明確病灶血管巢及瘺口的特點(diǎn),顯示供血動脈、引流靜脈的解剖細(xì)節(jié)及血流動力學(xué)情況。17例患者的CTPa與DSA診斷結(jié)果一致,但CTPa漏診3例動靜脈畸形病灶的1根供血動脈(1/21)及3根引流靜脈(3/23)。結(jié)論 :CTPa能夠準(zhǔn)確診斷顱內(nèi)動靜脈分流性疾病,并反映其動靜脈短路的病理特點(diǎn),但對于細(xì)小結(jié)構(gòu)的顯示不及DSA。CTPa對顱內(nèi)動靜脈分流性疾病的診斷具有重要的臨床應(yīng)用價值。
[Abstract]:Objective: to evaluate the clinical value of dynamic angiography (CTPA) based on 320 slice CT perfusion in intracranial arteriovenous shunt disease. Methods: the imaging data of 26 patients with intracranial arteriovenous shunt disease diagnosed by CTPa were analyzed retrospectively. The location, size and vascular architecture of the lesions were recorded. Among them, 17 patients were examined by DSA and compared with the results of DSA. Results among the 26 patients, 18 were arteriovenous malformations, 8 were arteriovenous fistula. CTPA was able to identify the characteristics of vascular nests and fistula orifices, and showed the supplying artery. The anatomical details and hemodynamics of drainage veins. The results of CTPa and DSA in 17 patients were consistent with those of DSA, but CTPa missed 1 / 21 of 1 / 21 donor artery in 3 cases of arteriovenous malformation and 3 / 23 of drainage veins. Conclusion the ratio CTPA can accurately diagnose intracranial arteriovenous shunt disease and reflect the pathological characteristics of arteriovenous short circuit, but it has important clinical application value in the diagnosis of intracranial arteriovenous shunt disease than that of DSA.CTPa.
