Objectives:
To find the correlation between radiologically proven improvement in cerebral hemodynamics with clinical improvement in patients undergoing cranioplasty.
Material And Methods:
The study is a prospective observational study of 10 cases, in M S Ramaiah Institute of Neurosciences, involving patients treated by a decompressive craniectomy for intractable intra cranial hypertension either due to trauma or stroke and afterwards underwent cranioplasty.
Results:
Of the 10 patients, 70% patients showing significant improvement in motor functions on Barthel index scale, 60% patients showed improvement in speech, mean duration from date of decompressive craniectomy to cranioplasty being 122.4days. Cerebral perfusion was remarkably better after cranioplasty, as demonstrated decrease in the Pulsatility index on the ipsilateral side of decompression on Trans cranial Doppler (<0.73 mean). This data also favored improved cerebral blood flow and permeability on the CT perfusion with increase in cerebral blood flow (CBF), Cerebral Blood Volume (CBV) and decrease in Time to Peak (TTP) and a positive outcome when correlated with Barthel index with P-values of 0.093, 0.017 and 0.001 respectively.
Conclusion:
Cranioplasty influences the cerebral hemodynamics after cranioplasty and has a positive correlation on the functional outcome and cerebral blood flow in the MCA territory.
