【摘要】：目的探讨单纯型和复合型先天性主动脉缩窄(COA)CT表现的差异及其临床意义。方法回顾性分析28例COA患者的CT表现,比较单纯型(n=12))和复合型(n=16)COA的缩窄范围、受累部位、狭窄程度、合并变异血管、心血管畸形和侧支循环的差异并行统计学检验。结果 28例中,病变范围:局限性COA 17例(60.7%),长段性COA 11例(39.3%)。病变部位:单纯型COA发生于左锁骨下动脉远端8例(28.6%)、胸主动脉3例(10.7%)、左颈总动脉-左锁骨下动脉1例(3.6%),复合型COA发生于升主动及主动脉弓6例(21.4%)、左颈总及左锁骨下动脉之间3例(10.7%)、左锁骨下动脉远端5例(17.9%)、胸主动脉2例(7.1%)。狭窄程度:单纯型为80.3±10.4%,复合型为68.5±7.3%(P=0.02)。合并血管变异:单纯型3例(10.7%),复合型7例(/25%)(P=0.000)。合并心血管畸形:单纯型少于复合型((P0.01))。伴侧支循环:单纯型12例(100%),复合型无侧支循环。结论单纯型和复合型COA的CT表现各有特征性,明确二者的差异有助于COA的早期诊断。
[Abstract]:Objective to investigate the difference of (COA) CT findings between simple and compound congenital aortic coarctation and its clinical significance. Methods the CT findings of 28 patients with COA were analyzed retrospectively. The constriction range, the site of involvement, the degree of stenosis, and the complication of variant blood vessels were compared between simple type (nong12) and compound type (nong16) COA. The differences between cardiovascular malformations and collateral circulation were examined statistically. Results of 28 cases, 17 cases (60.7%) had localized COA and 11 cases (39.3%) had long COA. Lesion site: simple COA occurred in 8 cases (28.6%) of left subclavian artery, 3 cases (10.7%) of thoracic aorta, and 1 case (3.6%) of left common carotid artery and left subclavian artery. Compound COA occurred in 6 cases (21.4%) of ascending active and aortic arch, 3 cases (10.7%) of left common neck and left subclavian artery, 5 cases (17.9%) of distal left subclavian artery, and 2 cases (7.1%) of thoracic aorta. The degree of stenosis was 80.3 卤10.4% in simple type and 68.5 卤7.3% in compound type (P0. 02). There were 3 cases (10.7%) of simple type and 7 cases (25%) of complex type (P0. 000). Cardiovascular malformation: simple type is less than compound type (P0.01). Collateral circulation: simple type 12 cases (100%), compound type without collateral circulation. Conclusion the CT features of simplex COA and compound COA are different, and the difference between them is helpful to the early diagnosis of COA.
