Objectives:
To investigate the indications, timings, and outcomes of decompressive craniectomy (DC) performed for malignant middle cerebral artery (MCA) infarctions at our tertiary care center.
Methods:
This retrospective case series involved patients who underwent DC for malignant MCA infarction at King Abdulaziz Medical City, Ministry of National Guard Health Affairs, Riyadh, between January 2012 and December 2018. Demographic, clinical, and radiological data were collected, and stroke- and surgery-related complications and discharge outcomes were assessed.
Results:
Eighteen patients (mean age: 50±10 years), of whom 13 (72%) were men, underwent DC during the study period. Of the patients, 9 (50%) had severe stroke (NIHSS 16-25), 10 (56%) had right MCA infarction, and 11 (61%) received either intravenous thrombolysis or endovascular thrombectomy or their combination. Indications for surgery included clinical deterioration as seen in 16 (89%) patients, ipsilateral pupillary dilatation as seen in 11 (61%) patients, and signs of raised intracranial pressure in 6 (33%) patients. Surgery was performed within 48 h in 14 (78%) patients. The mean Intensive Care Unit stay was 15±7 days. Seven (39%) patients were discharged home and 3 (17%) were transferred to an inpatient rehabilitation unit, and 2 (11%) patients died. All patients had stroke-related complications; one (6%) patient developed cerebrospinal fluid leak, 3 (17%) had sunken skin flap syndrome and wound infection each, and 2 (11%) developed epidural hematoma.
Conclusion:
The DC was life-saving in the our patients with malignant MCA infarction. Most of the patients had surgery within 48 hours. More than one-third of the patients were discharged home, while mortality occurred in only 2 patients. Moreover, stroke- and surgery-related complications were common in our cohort.
