Direct imaging of retroperitoneal hemorrhage following translumbar aortography was performed using computed tomography. Seven patients were scanned over the area of aortic entry immediately after undergoing angiographic examination. In five cases, there was definite evidence of periaortic hematoma, most commonly seen as a discrete soft tissue density with absorption coefficients between +20 and +35 EMI units. Other signs of retroperitoneal bleeding were less consistently present (e.g., loss of aortic contour, aortic displacement, and thickening of diaphragmatic crura). The clinical implications of detecting significant hemorrhage following translumbar aortography are also discussed.
采用计算机断层扫描对经腰主动脉造影术后的腹膜后出血进行直接成像。7例患者在接受血管造影检查后立即对主动脉进入区域进行扫描。5例有明确的主动脉周围血肿证据，最常见的表现为离散的软组织密度影，吸收系数在+20至+35 EMI单位之间。腹膜后出血的其他征象则不太一致出现（如主动脉轮廓消失、主动脉移位和膈脚增厚）。还讨论了经腰主动脉造影术后检测到大量出血的临床意义。
