Decompressive Craniectomy in Extensive Ischemic Stroke. An Experience in a Single Institution

Background Decompressive craniectomy (DC) is a valuable treatment for reducing early lethality in malignant intracranial hypertension (IH); however, it has been shown that the decision to implement DC in patients with extensive ischemic stroke should not be based solely on the detection of IH with the use of intracranial pressure (ICP) devices.Objective To establish the usefulness of DC in patients with extensive ischemic stroke who came to the emergency room during the period between May 2018 and March 2019.Methods This was an analytical, prospective, and longitudinal study whose population corresponded to all patients with a diagnosis of extensive ischemic stroke.Results The sample consisted of 5 patients, of which 3 were female and 2 males, the average age was 62.2 years old (minimum 49 years old, maximum 77 years old). Of all the patients who underwent DC, it was found that 80% of the patients did not present an increase in intracranial pressure. Decompressive craniectomy was not performed in a case that responded adequately to medical treatment. The mean values of ICP were 25 mmHg with a minimum value of 20 mmHg and a maximum value of 25 mmHg; in patients with a moderate value, the ICP averages were < 20 mmHg. The mortality was of 40% (RANKIN of 6 points).Conclusions Decompressive craniectomy is useful in extensive ischemic stroke. The decision to implement DC in patients with extensive stroke rests on clinicoradiological parameters. The monitoring of the IPC was not particularly useful in the early detection of the neurological deterioration of the patients studied.
