Microsurgical anatomy of the subcallosal artery.

Background And Purpose: The subcallosal artery [SCA, a branch of the anterior communicating artery (ACoA)] is not well described in the literature. However, the memory disorders that can occur after surgical repair of ruptured ACoA aneurysms might be related to infarction of the SCA. The objective of the present study was to perform a thorough anatomical assessment of the SCA.

Robot-Assisted Radiofrequency Ablation of a Sacral S1-S2 Aggressive Hemangioma.

Background: Aggressive vertebral hemangiomas are rare tumors of the spine. The treatment management strategy usually consists of vertebroplasty, radiation therapy, or, in rare cases of surgical strategy.
