Abstract

We performed thermal balloon angioplasty in 10 iliac arteries in 5 mongrel dogs. By perfusing a modified angioplasty balloon with hot (100 degrees C) saline, a mean balloon temperature of 84 degrees C was obtained. Angiographic and histologic follow-up at 6 months revealed no thrombosis or aneurysm formation but it did reveal fibrotic transformation of the media. Initial overdilatation was maintained in 9 of 10 arteries. We conclude that medial sclerosis induced by thermal balloon angioplasty does not result in aneurysm or thrombosis in dogs.

摘要

我们对5只杂种狗的10条髂动脉进行了热球囊血管成形术。通过向改良的血管成形术球囊灌注热（100摄氏度）盐水，球囊平均温度达到84摄氏度。6个月时的血管造影和组织学随访显示，未形成血栓或动脉瘤，但确实发现了中膜的纤维化转变。10条动脉中有9条维持了初始的过度扩张。我们得出结论，热球囊血管成形术诱导的中膜硬化在狗中不会导致动脉瘤或血栓形成。
