These include hemangioblastoma, hemangiopericytoma, meningioma, choroid plexus tumors, and several metastatic lesions. Given their vascularity, these tumors require additional diagnostic and interventional considerations. Properly identifying them on preoperative imaging studies is critical to determining the need for angiography and planning the appropriate surgical approach, as these tumors have a propensity for high blood loss during surgical resection. Angiograms are often important prior to surgery to identify the vascular supply of these lesions and in some cases to embolize these vessels to mitigate blood loss. Careful selection of patients for embolization is imperative, as there is significant risk of stroke from these procedures. In our experience, very large tumors, those with difficult to access blood supplies, and those with multidirectional blood supplies are the most ideal candidates. More so than in other tumor operations, the surgeon must identify and coagulate the blood supply early in the sequence of the operation to avoid high blood loss. Correctly determining which vessels are supplying the tumor and which vessels are “en passage” is critical to avoiding strokes. Similar to other tumors, postoperative follow-up in these patients is dependent on the pathology. T2 - Decision Making in Neurovascular Disease ER -
