The Kensey dynamic angioplasty catheter is a new device for recanalization of peripheral arterial occlusions. Twelve patients with segmental occlusions who were not considered candidates for conventional bypass surgery because of cardiovascular risk factors were studied. Four of the patients were treated in the operating room. Two had excellent primary results in limb salvage situations, and recanalization of an occluded femoropopliteal bypass graft was successful in another. Bilateral iliac recanalizations in the fourth patient were locally successful but did not prevent the patient's death from advanced ischemic disease. Eight patients were treated percutaneously. Initial recanalization was successful in seven. Four had early reocclusions and required amputation below the knee. One suffered distal embolization after recanalization of a 6-cm popliteal segment and underwent above-the-knee amputation. Long-term follow-up (7-18 months) in the other three patients with successful primary recanalizations has confirmed patency of the recanalized segments.
肯西动态血管成形术导管是一种用于外周动脉闭塞再通的新装置。对12例因心血管危险因素而不被认为适合传统搭桥手术的节段性闭塞患者进行了研究。其中4例患者在手术室接受治疗。2例在肢体挽救方面取得了优异的初步结果，另一例成功实现了闭塞的股腘动脉搭桥移植血管再通。第4例患者双侧髂动脉再通在局部取得成功，但未能阻止该患者死于晚期缺血性疾病。8例患者接受了经皮治疗。7例首次再通成功。4例早期再次闭塞，需要进行膝下截肢。1例在6厘米腘动脉节段再通后发生远端栓塞，接受了膝上截肢。对另外3例首次再通成功的患者进行长期随访（7 - 18个月），证实了再通节段的通畅。
