Selective arterial embolization in the treatment of lesions of the musculoskeletal apparatus.

The authors describe 42 cases of lesions of the musculoskeletal apparatus (traumatic, pseudoneoplastic or tumorous) in which selective arterial transcatheter percutaneous embolization (SAE) was indicated. In 3 patients SAE was not performed because the angiography had shown it to be too dangerous for the spinal cord. Out of 39 patients 2 were embolized in order to stop unrestrainable hemorrhaging (1 post-traumatic and 1 post-bioptic), 7 in order to reduce intraoperative bleeding, while in 7 cases (aneurysmal bone cyst, angioma of bone) the aim was curative. In the remaining 23 patients SAE was performed for adjuvant (8) or palliative (15) purposes in association with radio-and/or chemotherapy (11). In these last 15 cases the clinical results obtained were good in 67% of the cases, with partial or total regression of pain. Healing was obtained in 100% of the patients treated for curative purposes.
