Insights

Decompressive craniectomy after intra-arterial thrombolysis for malignant middle cerebral artery stroke showed similar outcomes and complication rates compared to decompressive craniectomy without prior thrombolysis.

Area of Science:

  • Neurosurgery
  • Neurology
  • Vascular Surgery

Background:

  • Malignant middle cerebral artery (MCA) stroke often requires decompressive craniectomy (DC).
  • The role of intra-arterial thrombolysis (IAT) prior to DC in these cases is not well-established.
  • Limited data exist on the safety and efficacy of combining IAT with DC for MCA stroke.

Purpose of the Study:

  • To compare outcomes and complications in patients undergoing DC after IAT versus DC without prior IAT.
  • To evaluate the impact of IAT on the effectiveness of DC for malignant MCA stroke.
  • To identify factors influencing outcomes in patients treated with DC for MCA stroke.

Main Methods:

  • Retrospective comparison of consecutive patients with MCA strokes.
  • Patients were divided into two groups: those who underwent DC after IAT and those who underwent DC without prior thrombolysis.
  • Outcomes were assessed at 3 months using the modified Rankin scale, along with mortality and complication rates.

Main Results:

  • Fifteen of 30 patients undergoing DC for space-occupying edema after MCA stroke received prior IAT.
  • Favorable outcomes (modified Rankin scale 0-3) were observed in 47% of IAT patients versus 27% of non-IAT patients (p=0.45).
  • No significant differences in mortality or major complications were found between the groups. Older age and hypertension predicted unfavorable outcomes.

Conclusions:

  • Decompressive craniectomy following intra-arterial thrombolysis does not increase complications compared to DC alone for malignant MCA stroke.
  • The study found no significant difference in outcomes between patients who received IAT before DC and those who did not.
  • IAT prior to DC may not alter the overall outcome or complication profile of this critical intervention.
