AI Article Synopsis

  • The study investigates the impact of decompressive craniectomy (DC) on patients with symptomatic intracerebral hemorrhage (sICH) following acute ischemic stroke, comparing outcomes between those who had surgery and those treated medically.
  • It analyzed data from 85 patients across 8 stroke centers, revealing that DC patients were younger, had longer ICU stays, and showed better functional outcomes at 90 days compared to non-DC patients, especially if they were younger and did not have a history of cancer.
  • The results indicate that the DC group had lower in-hospital mortality rates and came out with improved scores on the modified Rankin Scale, suggesting a potential benefit of surgery for select patients with severe sICH.

Article Abstract

Objective: Symptomatic intracerebral hemorrhage (sICH) after stroke is a devastating neurological complication. Current guidelines support a "possible benefit" of decompressive craniectomy (DC) for large supratentorial sICH with significant mass effect.

Methods: The authors conducted a retrospective study of 8 comprehensive stroke centers. They included all patients who sustained an sICH after acute ischemic stroke (AIS), as defined by the Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST), from January 2016 to December 2020. They compared patients who underwent DC to those who were treated with standard medical treatment to measure functional outcome at 90 days, primarily as defined by the modified Rankin Scale (mRS) and secondarily by the Glasgow Outcome Scale-Extended (GOS-E).

Results: Eighty-five patients were identified, 26 of whom (30.5%) underwent DC. Patients who underwent DC were younger (58 years [DC] vs 76 years [no DC], p < 0.001). No patient with a previous history of cancer underwent DC (n = 14, p = 0.004). Twenty-five patients (96.2%) in the DC group underwent thrombectomy versus 54 (91.5%) in the non-DC group (p = 0.443). Patients who underwent DC had a longer ICU stay (median [IQR] 240 [38-408] hours vs 24 [5-96] hours in non-DC patients, p = 0.002). At 90 days, 3 patients (4.1%) had obtained an mRS score of 0-2 and 10 patients (11.7%) an mRS score of 0-3. Patients who had improved functional outcome were younger (mRS score, OR 1.06, 95% CI 1.01-1.10, p = 0.012). Patients with a history of cancer had worse 90-day mRS scores (OR 8.49, 95% CI 1.54-159, p = 0.046). The rate of in-hospital mortality or discharge to hospice was significantly higher in the non-DC cohort (10 [38.5%] patients in the DC cohort vs 38 [64.4%] in the non-DC cohort, p = 0.026). Ninety days later, patients who underwent DC were more likely to have improved outcome (mRS mean rank 30.0 vs 40.0, p = 0.027). In multivariable analysis, history of cancer (OR 12.2, 95% CI 1.26-118, p = 0.031) and older age (OR 1.07, 95% CI 1.02-1.13, p = 0.011) increased the odds of worse mRS outcomes while DC did not (OR 1.34, 95% CI 0.357-5.03, p = 0.665).

Conclusions: DC after sICH did not improve functional outcome at 90 days according to multivariable analysis, although younger age and absence of previous cancer history were associated with improved outcomes.
