Clinical records of the first 45 consecutive patients (66 lesions) in whom the Probe TM a balloon on the wire, was used for percutaneous transluminal coronary angioplasty have been reviewed. The aim of this analysis was to establish the efficacy and safety of this device. Majority of the lesions taken up were considered severe and difficult to cross. The probe was the 1st catheter used in 51 lesions (77%) and in 15 lesions (23%) it was used after other balloon catheters. In 88% (58/66) of lesions treated the Probe reduced the stenosis to less than 50% of the luminal diameter. Of the 45 patients treated 39 (87%) had a successful result. Of the 19 patients with multiple lesions 74% (14/19) had complete revascularisation and in 16% (3/29) had the most significant vessel dilated. Two patients (3%) required urgent coronary artery bypass surgery for acute occlusions. There was no hospital death. Of 50 probe devices used 5 (10%) malfunctioned: the balloon ruptured (at 5 Bars pressure) in 2 instances, balloon twisted causing "Volvulous" in 1 and balloon failed to deflate in 2 cases. The probe has significant advantages over other balloon systems for treating severe coronary lesions because of its low profile. It is however a delicate catheter system and prone to malfunction if not handled with care. Our results show that it is an excellent system for opening difficult and tight coronary lesions.
对连续使用Probe TM（一种带导丝球囊）进行经皮腔内冠状动脉成形术的前45例患者（66处病变）的临床记录进行了回顾。该分析的目的是确定该设备的有效性和安全性。所处理的大多数病变被认为严重且难以通过。在51处病变（77%）中，Probe是首个使用的导管，在15处病变（23%）中，它在其他球囊导管之后使用。在88%（58/66）接受治疗的病变中，Probe将狭窄程度降低至管腔直径的50%以下。在接受治疗的45例患者中，39例（87%）取得了成功结果。在19例有多发病变的患者中，74%（14/19）实现了完全血运重建，16%（3/29）实现了最严重血管的扩张。2例患者（3%）因急性闭塞需要紧急冠状动脉搭桥手术。无院内死亡病例。在使用的50个Probe设备中，5个（10%）出现故障：2例球囊破裂（压力为5巴时），1例球囊扭曲导致“肠扭转”，2例球囊未能放气。由于其外形小巧，Probe在治疗严重冠状动脉病变方面比其他球囊系统具有显著优势。然而，它是一个精密的导管系统，如果操作不当容易出现故障。我们的结果表明，它是打开困难和严重冠状动脉病变的优秀系统。
