Treatment of Takayasu's arteritis with thoracoabdominal aorta stenosis by percutaneous transluminal angioplasty(PTA) / 中国微创外科杂志

ABSTRACT

Objective To summarize our experience in percutaneous transluminal angioplasty(PTA) in the management of thoracoabdominal aortic stenosis of Takayasu's arteritis. Methods From 1987～2001, 12 patients of Takayasu's arteritis with thoracoabdominal aortic stenosis underwent PTA. Aortography and pressure of stenotic segment of arota before and after angioplasty were used to evaluate efficacy. Color Doppler ultrasound examination and Doppler segmental pressure measurement were used in follow-up. Results Success was achieved in all cases without mortality and serious complications except for 1 case of acute thrombosis of iliofemoral artery. The residual stenosis were less than 50% in all cases and the pressure gradient was 5 0mmHg～10 5 mmHg with average pressure being 7 2 mmHg after angioplasty ,although they were 25mmHg～46 mmHg averaging of 37 7 mmHg before angioplasty. All cases were followed up for 9(12～72) months and the result was good without lumen restenosis and obstruction. Conclusions PTA is the first choice for Takayasu's arteritis of thoracoabdominal aortic stenosis of local size and proved to be safe, effectiveand economical. It is also effective for long size cases. It is not necessary to dilate aorta stenosis to normal size, and reducing pressure gradient effectively is enough.
