Beneficial impact of early cranioplasty in patients with decompressive craniectomy: evidence from transcranial Doppler ultrasonography.

摘要: A cranioplasty (CP) is often performed after decompressive craniectomy (DC) for cosmetic and protective reasons; however, the timing of CP needs to be better evaluated maximize beneficial outcomes neurological recovery. We investigated effects mechanisms early compared late on recovery, from perspective cerebral blood flow (CBF). This study retrospectively reviewed 43 patients undergoing (<12 weeks) or (≥12 weeks) DC. The CBF velocity was measured by transcranial Doppler ultrasonography analyzed prior in every patient. Complications were recorded. middle artery (MCA) ipsilateral increased both groups statistically different between (p < 0.05). On contralateral side, MCA group, but not group. Change (expressed as delta, Δ) defined difference pre- postoperative status groups. significant detected Δ side There no differences incidence complications Our results show post-DC improvements receiving CP < 12 weeks DC, those CP ≥ 12 weeks Therefore, has potential benefits perfusion.
