[Revascularization of supra-aortic trunks in Takayasu's arteritis].

INTRODUCTION

Takayasu's disease is an inflammatory arteritis mainly affecting the aorta, its main divisional branches and pulmonary arteries. The arterial damage during Takayasu's disease is essentially occlusive and preferentially affects supra-aortic trunks. Indications for revascularization of supra-aortic trunks are clear but results are rarely reported. The purpose of this study was to evaluate the results of supra-aortic trunk revascularization in Takayasu's arteritis.

PATIENTS AND

METHODS

We report a retrospective study conducted between 2012 and 2018 about patients with Takayasu's arteritis who underwent revascularization of supra-aortic trunks.

RESULTS

Our series consisted of six patients. All patients were female. The average age was 29 (range 18-48) years. The operative indication was cerebrovascular ischemic symptoms in five patients and intermittent claudication of the upper limb in one. We performed aorto-bi-carotid bypass in four patients, a subclavian artery angioplasty in one and a vertebral artery angioplasty in one. At 1 month, operative mortality was zero and morbidity was marked by hemorrhagic stroke in one patient operated by conventional surgery. The average follow-up was 4 years (1.8). During the follow-up, one patient was reoperated after 18 months for an anastomotic false aneurysm in the ascending aorta. We noted a favorable outcome with total resolution of the symptomatology for the other patients and Doppler ultrasound confirmed patency during follow-up.

CONCLUSION

Surgical revascularization of supra-aortic trunks in Takayasu's arteritis can be associated with a risk of stroke and a risk of anastomotic pseudoaneurysms. Endovascular revascularization appears to be less invasive but its long-term results are rarely reported.
