Surgical pitfalls in pinealoma surgery.
The author has treated 30 cases of pinealoma by the infratentorial supracerebellar approach with the patient in the sitting position. Long-term outcome has been excellent in 26 cases, poor in 1, and death in 3 cases. Postoperative deaths were due to: (i) high venous pressure in the jugular vein caused by a tourniquet placed around the neck to prevent air-embolism, making hemostasis more difficulty, (ii) the absence of retraction resulting in a narrow surgical field when acute brain swelling developed, and (iii) high coagulation and ablation of the precentral cerebellar vein causing diffusion thrombosis of deep veins. The details of these cases are presented in this article.
