Summary

The aim of this study is to assess blood flow velocity in middle cerebral artery measured by transcranial doppler to determine the efficacy of SCG block in decreasing incidence or severity of vasospasm after MCA aneurysm surgery.

Conditions

  • Brain Aneurysm
  • Aneurysm, Ruptured

Interventions

PROCEDURE

Superior Cervical Ganglion Block

Under X-ray guidance, a 23-gauge radiofrequency top-pole needle with an active tip of 5 mm is inserted for test blockade. The needle is directed at the facet joint of the 3rd and 4th cervical vertebrae.The needle is introduced parallel to the radiographic projection and is projected as a dot approximately 1 cm anterior to the spine. The radiographic projection is then changed to lateral, and the needle is slowly advanced until the tip was situated at the anterior border of the third cervical vertebra. On the anteroposterior projection, the tip of the needle is projected over the lateral part of the facetal column. When the tip of the needle is in position, 0.3 mL of Omnipaque is injected. On the transverse projection, the contrast is distinctly anterior to anterior border of the vertebral bodies, and in the anteroposterior projection, the contrast is seen spreading in a space overlying the facetal column in a cranial as well as caudal direction.
