【摘要】：目的探討冠狀動(dòng)脈(簡(jiǎn)稱冠脈)異常起源肺動(dòng)脈(ACAPA)的CTA圖像特征。方法回顧性分析本院收治的24例ACAPA的患者資料,分析其CTA表現(xiàn),并與手術(shù)結(jié)果對(duì)照。結(jié)果 24例患者中,發(fā)生于左冠脈20例(20/24,83.33%)、右冠脈1例(1/24,4.17%)、前降支1例(1/24,4.17%)、回旋支2例(2/24,8.33%)。冠脈異常起源部位:起源于肺動(dòng)脈竇或肺動(dòng)脈主干后壁11例(11/24,45.83%)、左壁7例(7/24,29.17%)、右壁4例(7/24,16.67%),起源于左肺動(dòng)脈2例(2/24,8.33%)。側(cè)支循環(huán):嬰兒型5例,冠脈間未見側(cè)支血管;成人型19例,其中左/右冠脈異常起源16例,前降支異常起源1例,回旋支異常起源2例。合并雙前降支和冠脈在升主動(dòng)脈壁內(nèi)走行各1例。外科手術(shù)19例。術(shù)后CTA復(fù)查5例,1例人工管道與回旋支吻合口局限性狹窄,1例右心室流出道再狹窄,1例冠脈假性動(dòng)脈瘤。結(jié)論 CTA可清晰顯示冠脈異常起源部位、與升主動(dòng)脈的距離、側(cè)支血管、合并其他冠脈畸形,有助于術(shù)前制定手術(shù)方式及術(shù)后隨訪。
[Abstract]:Objective to investigate the CTA features of the anomalous origin of coronary artery (CAPA) in pulmonary artery. Methods the data of 24 patients with ACAPA treated in our hospital were retrospectively analyzed. The CTA findings were analyzed and compared with the surgical results. Results among the 24 patients, 20 cases occurred in the left coronary artery, 20% in the left coronary artery, 83.33% in the left coronary artery, 1 case in the right coronary artery, and 1 case in the right coronary artery. The anterior descending branch (1 / 1 / 24 / 4.17), the circumflex branch (2 / 2 / 248.33), the origin of the abnormal coronary artery (11 / 24) originated from the pulmonary sinus or the posterior wall of the main pulmonary artery (11 / 24). 45.83%, 7 cases on the left wall and 29.17% on the left wall, 4 cases on the right wall, 7 / 24% on the right wall and 16.67% on the right wall, which originated from the left pulmonary artery in 2 cases (2 / 24). 8.33 collateral circulation: there were 5 cases of infantile type with no collateral vessels between the coronary arteries. There were 19 cases of adult type, including 16 cases of abnormal origin of left / right coronary artery and 1 case of abnormal origin of anterior descending branch. There were 2 cases of abnormal origin of circumflex branch, 1 case of double anterior descending branch and 1 case of coronary artery walking in ascending aortic wall, 19 cases of surgical operation, and 1 case of local stenosis of anastomotic stoma between artificial conduit and circumflex branch in 5 cases after CTA. One case with right ventricular outflow tract restenosis and one case with pseudoaneurysm of coronary artery. Conclusion CTA can clearly show the origin of the abnormal coronary artery, the distance from the ascending aorta, the collateral vessels, and other coronary malformations. It is helpful to establish the operation method before operation and follow up after operation.
