Intraaortic balloon counterpulsation has been widely applied for treatment of left ventricular pump failure and intractable angina. However, its use has been limited by the difficulty of balloon insertion in some patients and vascular complications in others. An AVCO intraaortic balloon was modified by the addition of a central lumen to allow pressure monitoring, injection of contrast medium and passage of a guide wire. The device was successfully used in 15 of 16 patients, including 4 of 5 in whom attempts to place a standard balloon catheter had failed. No significant vascular complications occurred in any patient. The modified balloon catheter appears to increase the efficacy and safety of insertion and allows immediate and continuous monitoring of arterial pressure.
主动脉内球囊反搏已广泛应用于治疗左心室泵衰竭和顽固性心绞痛。然而，其应用受到一些患者球囊插入困难以及另一些患者血管并发症的限制。一种AVCO主动脉内球囊通过增加一个中央腔进行了改良，以允许压力监测、注射造影剂和导丝通过。该装置在16例患者中的15例成功使用，包括5例中4例尝试放置标准球囊导管失败的患者。所有患者均未发生严重血管并发症。改良后的球囊导管似乎提高了插入的有效性和安全性，并允许对动脉压进行即时和连续监测。
