The function of ventriculoperitoneal shunts was evaluated by ultrasonography in 17 patients. In 10 of 15 patients with properly functioning shunts, a small amount of free intraperitoneal fluid was found. However, absence of demonstrable fluid did not reliably indicate shunt malfunction. No asymptomatic patients had large amounts of ascites or loculated fluid collections, both of which were considered pathologic in shunt patients.
通过超声检查对17例患者的脑室腹腔分流术功能进行了评估。在15例分流功能正常的患者中，有10例发现腹腔内有少量游离液体。然而，未发现明显液体并不能可靠地表明分流功能障碍。没有无症状患者出现大量腹水或局限性积液，这两种情况在分流患者中均被视为病理性的。
