Application of absolute alcohol in operations for giant meningiomas with rich blood supply / 中华神经医学杂志

ABSTRACT

Objective To evaluate the effectiveness of absolute alcohol in hemostasis in surgical resection of giant meningiomas with rich blood supply. Methods Twelve patients with giant meningiomas with rich blood supply were injected with absolute alcohol (8.5-27 mL, mean 11.2 mL) in the operations, and the tumors were resected under microscope. Results The tissues in the injection areas turned white and the tumors became hardened after the injection. The bleeding of the tumor surface and section was obviously decreased or even stopped. The quantities of bleeding were 48-154 mL in the operations, with an average of 67 mL. Total tumor resection was achieved in 11 patients (91.6%) and partial resection in 1 patient. No complications associated with the surgery were found in these cases. Conclusion Injection of absolute alcohol for hemostasis in surgical removal of giant meningiomas with rich blood supply is convenient and effective and can be widely applied in clinical practice.
