Risk of internal carotid artery stenosis or occlusion after single-fraction radiosurgery for benign parasellar tumors.

CONCLUSIONS: New or progressive ICA stenosis/occlusion was common after SRS for CSM but was not observed after SRS for GHPA, suggesting a tumor-specific mechanism unrelated to radiation dose. Pre-SRS ICA encasement or constriction increases the risk of ICA stenosis/occlusion; however, the risk of ischemic complications is very low. PMID: 31653808 [PubMed - as supplied by publisher]
