[Pulmonary embolism in neurosurgical patients]

Pulmonary embolism (PE) is a serious problem for neurosurgical patients because of high risk of mortality and the need to choose effective and safe anticoagulation.

To analyze the patients with PE after neurosurgical interventions.

A prospective study was performed at the Burdenko Neurosurgical Center between January 2021 and December 2022. Inclusion criteria were neurosurgical disease and PE.

In accordance with inclusion criteria, we analyzed 14 patients. Mean age was 63 [45.8; 70.0] years. Four patients died. PE was a direct cause of death in 1 case. PE occurred in 5.14±3.68 days after surgery. Anticoagulation was safely implemented in 3 patients with PE on the first day after craniotomy. In a patient with massive PE several hours after craniotomy, anticoagulation resulted hematoma with brain dislocation and death. Thromboextraction and thrombodestruction were used in 2 patients with massive PE and high risk of mortality.

Despite low incidence (0.1%), PE is a serious problem in neurosurgical patients due to the risk of intracranial hematoma under effective anticoagulant therapy. In our opinion, endovascular interventions with thromboextraction, thrombodestruction or local fibrinolysis are the safest in the treatment of PE after neurosurgery. Individual approach considering clinical, laboratory data, advantages and disadvantages of a particular anticoagulant drug is required when choosing the tactics of anticoagulation. Further analysis of a larger number of clinical cases is needed to develop the guidelines for the management of neurosurgical patients with PE.
