摘要

Background: Venous bleeding induced by intercavernous sinus injury during sellar dural opening is a challenging intraoperative complication and is difficult to treat in transsphenoidal surgery. To date, few studies concerning the management of intercavernous sinus bleeding have been reported. Aims: Our aim was to assess the clinical outcomes of a new hemostasis technique utilizing nonpenetrating titanium clips for management of intercavernous sinus bleeding. Materials and Methods: From January 2007 to July 2008, 242 pituitary tumors were operated using a transnasal transsphenoidal approach. A new technique involving a specially devised clip applier and titanium clips was used to control venous bleeding in 13 (5.4%) patients who exhibited a prominent intercavernous sinus. All patients were evaluated clinically and radiologically at 9 to 24 months, and postoperative magnetic resonance imaging (MRI) was performed at 3 to 18 months. Results: No operation was interrupted or aborted due to ineffective bleeding control, and there was no delayed bleeding noted as a complication. No complications related to the use of the device occurred. Imaging studies revealed no evidence of significant clip artifact. Conclusions: Our surgical experience has revealed that this new hemostasis technique can be a safe, rapid and effective method for control of intercavernous sinus bleeding during sellar dural opening in transsphenoidal surgery. However, a further prospective study to evaluate this method more fully is planned.
