Background:
This study was performed to investigate the safety and outcome of one-stage hybrid endovascular and microsurgical treatment of intracranial hypervascular tumors.
Methods:
The blood supply of the tumor was endovascularly embolized just before microsurgery in a one-stage fashion. Clinical data regarding the preoperative neurological status, tumor characteristics, hybrid treatment details and complications, intraoperative blood loss, and postoperative outcomes were collected prospectively and then analyzed.
Results:
Beginning in July 2016, 13 patients (5 women, 8 men) with intracranial hypervascular tumors were enrolled in this study, with a mean age of 48.2 ± 10.9 years. The patients' tumors comprised seven hemangioblastomas, three hemangiopericytomas, two meningiomas, and one mesenchymal chondrosarcoma. The mean maximum tumor diameter was 54.9 ± 21.5 mm. No major procedural complications occurred except catheterization-related bleeding in one patient. The mean percentage of tumor devascularization was 65.0%±17.5%. Gross total resection was achieved in 12 patients (92.3%). The mean blood loss volume during microsurgical resection was 703.8 ± 886.8 mL (range, 150-3600 mL). Symptoms improved in three patients and remained stable in six patients.
Conclusions:
One-stage hybrid embolization before intracranial hypervascular tumor resection is a safe and effective procedure to decrease intraoperative blood loss. It can prevent or treat embolization-related complications in a timely manner and avoid the risk of multiple surgical procedures.
