[Iatrogenic venous pathology and post-radiosurgery swollen arm. Apropos of 100 cases].

Lymphostasis of the upper limb, succeeding the radiosurgical treatment of breast cancer, has been known for some time, along with the clinical entity generally called "swollen arm". Post radiosurgical venous disorders have, however, been much less studied, and so the author's survey is based on a systematic, clinical, and phlebo-lympho-scintigraphical study of 100 case histories. Out of the 100 cases studied, almost 80% presented mixed lympho-venous anomalies, whilst 25% of the cases proved to be "swollen arm" of purely venous origin. Finally the author analyses the different vascular lesions encountered in the follow-up of radio-surgical treatment and the therapeutic conclusions to be drawn from these.
