====== Posterior Fossa Surgery Complications ======

===== Posterior fossa epidural hematoma =====

Postoperative uncontrolled bleeding from the dural venous sinus can sometimes cause an insidious-onset or delayed posterior fossa EDH

epidural hematoma after posterior fossa surgery. J Clin Neurosci. 2018

===== Lateral sinus thrombosis =====
 
Incidental radiological [[lateral sinus thrombosis]] following [[posterior fossa surgery]] has an incidence of 6.7%. To further define the benefit-to-risk ratio of a treatment-dose [[anticoagulant therapy]], a prospective trial should be considered

Parraga E, Meder JF, Sauvageon X, Devaux B, Oppenheim C, Pallud J. Presentation
and management of lateral sinus thrombosis following posterior fossa surgery. J

)).

===== Intracerebral hemorrhage =====

[[Intracerebral hemorrhage]]s after interventions of the [[posterior fossa]] is a very rare complication, with very little literature and its precise incidence is unknown (range of 0.4-1.6%).

The principal measures in the management of these cases include early diagnosis, detection of possible coagulation disorders, continual monitoring, and maintenance of adequate cerebral perfusion. Surgical treatment is recommended in cases of the presence of mass effect or diffuse edema not yielding to clinical treatment. High rates of mortality and morbidity are observed
