Digital subtraction angiography was used for postoperative evaluation of seven patients who underwent the Senning procedure for repair of d-transposition of the great arteries. Their ages ranged from 2.5 to 3 years. The patients were premedicated with methohexital (25 mg/kg rectally), and 0.3 to 0.4 ml/kg of diatrizoate was injected into a peripheral vein through a plastic needle. Images were obtained on a Technicare DR-960 or Diasonics DA 100 digital angiographic unit at four frames per second using 256 X 256 matrix and a 6 inch (15.24 cm) field size. In all patients, the venous systems, cardiac chambers and great arteries were well visualized. Two patients had obstruction of the superior vena cava with a dilated azygos vein draining into the inferior vena cava. One patient had severe obstruction of the left pulmonary artery. Digital subtraction angiography is safe and easy to perform and appears to be a valuable alternative method for evaluating patients after surgical repair of transposition of the great arteries. The small amount of contrast material required and the low radiation dose make it attractive for use in children.
数字减影血管造影术用于对7例接受大动脉d型转位修复森宁手术的患者进行术后评估。他们的年龄在2.5至3岁之间。患者术前用美索比妥(25mg/kg直肠给药)进行预处理,通过塑料针将0.3至0.4ml/kg的泛影葡胺注入外周静脉。使用256×256矩阵和6英寸(15.24cm)视野大小,以每秒4帧的速度在Technicare DR - 960或Diasonics DA 100数字血管造影设备上获取图像。在所有患者中,静脉系统、心腔和大动脉均清晰可见。2例患者存在上腔静脉梗阻,奇静脉扩张并汇入下腔静脉。1例患者有左肺动脉严重梗阻。数字减影血管造影术安全且易于实施,似乎是评估大动脉转位手术修复后患者的一种有价值的替代方法。所需造影剂用量少且辐射剂量低,使其在儿童中使用具有吸引力。
