IntroductionDecompressive craniectomy is an important method for managing refractory intracranial hypertension. Although decompressive craniectomy is a relatively simple procedure, various complications may arise. The aim of our paper was to determine the incidence of complications of decompressive craniectomy in patients with head injury and to analyse their risk factors.MethodsWe retrospectively analysed a group of 94 patients after decompressive craniectomy for head injury between 01 Jan 2014 and 31 Dec 2018. Postoperative complications were evaluated based on clinical examination and postoperative CT scan. The impact of potential risk factors on the occurrence of complications was assessed (age, worse initial clinical condition, any haemocoagulation disorder).ResultsTwenty patients died within the first month after surgery. Control CT scan showed one complication in 78 patients (83%), while 46 patients (49%) had more than one complication. We had to reoperate 22 patients (23.4%) due to a complication. The following complications were found: postoperative acute subgaleal/subdural haematoma (30× - 32%), subgaleal/subdural cerebrospinal fluid effusion (29× - 31%), soft tissues oedema (29× - 31%), haemorrhagic progression of brain contusion (17× - 18%), malignant brain oedema (8× - 8.5%), hydrocephalus (8× - 8.5%), temporal muscle atrophy (7× - 7.5%), peroperative massive bleeding ( 6× - 6.4%), epilepsy (4× - 4.3%), syndrome of the trephined (2× - 2.1%), skin necrosis (2× - 2.1%). Patients with a haemocoagulation disorder had a significantly higher incidence of complications (p=0.01).ConclusionComplications of decompressive craniectomy after head injury are frequent. The potential benefit of decompressive craniectomy can be adversely affected by the occurrence of many complications.
