[Post-irradiation axillo-subclavian arteriopathy: surgical revascularization].
Post-irradiation axillo-subclavian arteriopathy can develop 6 months to 20 years after radiotherapy. Incidence estimated from duplex scan screening is about 30%, half of the cases having no hemodynamic significance. In our experience, asymptomatic lesions are the most common. Nevertheless, we have observed since 1978, 38 symptomatic patients including 23 with either acute ischemia (8 patients), or chronic ischemia (15 patients) requiring revascularization. We used an endovascular approach in 8 and open surgery in 15. A bypass graft was performed in 13 patients, using a vein (8 patients) rather than a prosthesis (5 patients), implanted in healthy territory, proximally or in the common carotid (11 patients) or the proximal subclavian (2 patients), and distally in the axillary artery (5 patients) or the brachial artery (8 patients). One venous bypass became occluded postoperatively. The other bypasses remained patent during follow-up of over 10 years. There of the five prosthetic bypassess gradually failed without recurrence of critical ischemia. Other revascularization procedures included endarterectomy and thrombectomy. In the long term, functional prognosis mainly depended on the frequently associated involvement of the plexus in the post-irradiation changes, which, together with the revascularization procedure, also required neurolysis in 11 patients, two omental covers and a free musculocutaneous transfer in 9 patients.
