POSTOPERATIVE HAEMORRHAGIC COMPLICATIONS IN VESTIBULAR SCHWANNOMA SURGERY: LITERATURE REVIEW AND A DESCRIPTION OF THREE CLINICAL OBSERVATIONS
Haemorrhagic complications are associated with the highest mortality rate in the structure of complications in vestibular schwannomas surgery. However, these complications are usually mentioned only briefly in studies where the authors report the overall results of vestibular schwannomas removal operations. The article presents a literature review and a description of 3 clinical observations with postoperative cerebello-pontine angle hematomas. Based on the results of the analysis of the world experience in the treatment of patients with this type of complication, the risk factors were identified, and a set of surgical measures for the prevention of postoperative hemorrhagic complications in the surgery of vestibular schwannomas was proposed. We have submitted an original classification of the sources of postoperative hematomas and determined the decisive role of the earliest possible revision interventions in the treatment outcomes for this category of patients.
