Ventricular shunts were evaluated by a shuntographic technique using metrizamide for the contrast material and delayed spot films and computed tomography (CT) to evaluate shunt function. Thirty hydrocephalic patients were studied who had clinical presentations of shunt malfunction. Fifty-two shuntograms were obtained; most demonstrated the cause of shunt malfunction. No contrast-related complications resulted from the procedure. Diagnostic accuracy was greatly improved by this method, since both anatomic and functional evaluations could be performed. In patients with normal studies, unnecessary surgery was eliminated; in abnormal shuntograms, the duration of surgery and the likelihood of complications were reduced because the surgeons knew the exact anatomic derangements to be corrected.
采用以甲泛葡胺为造影剂的分流造影技术、延迟点片及计算机断层扫描（CT）对脑室分流进行评估，以评价分流功能。对30例有分流功能障碍临床表现的脑积水患者进行了研究。共获得52张分流造影照片；大多数显示了分流功能障碍的原因。该操作未导致与造影剂相关的并发症。由于可以同时进行解剖学和功能评估，这种方法大大提高了诊断准确性。在检查结果正常的患者中，避免了不必要的手术；在分流造影异常的患者中，由于外科医生了解需要纠正的确切解剖紊乱情况，手术时间和并发症发生的可能性降低。
