Does intravascular coagulation contribute to the operative mortality for large acoustic neuromas?

Does intravascular coagulation contribute to the operative mortality for large acoustic neuromas?

Three cases of abnormal bleeding during suboccipital excision of large acoustic neuroma are reported. The possible role of limited operative intravascular coagulation is discussed.

Platelet ADP receptors contribute to the initiation of intravascular coagulation.

While the adenosine 5'-diphosphate (ADP) pathway is known to enhance thrombus formation by recruiting platelets and leukocytes to the primary layer of collagen-adhering platelets, its role for the initiation of coagulation has not been revealed. Ex vivo inhibition of the P2Y12 ADP receptor by clopidogrel administration diminished the rapid exposure of tissue factor (TF), the major initiator of ...

Acoustic Neuromas.

Patients with acoustic neuromas have several treatment options that include observation, surgical resection, stereotactic radiosurgery, and fractionated radiotherapy. Resection is indicated for patients with larger tumors that have caused major neurologic deficits from brain compression. Surgeons perform stereotactic radiosurgery as the main alternative to acoustic tumor resection with the goal...

Bilateral 'acoustic' neuromas.

Cystic acoustic neuromas.

Predominantly cystic acoustic neuromas are rare and they usually present with clinical and radiological features different from their more common solid counterparts. Two cases of cystic acoustic neuromas are reported here.
