[The influence of neck-dissection operations on cervical and cerebral blood circulation]

The authors conducted examination of blood flow velocity in medial cerebral artery using Trans Cranial Doppler method and calculated pulsatility index (PI) in 35 patients after neck dissection operation. Similarly 35 patients after neck dissection had duplex Doppler examination of common and internal carotid arteries performed. Pulsatility and resistance indexes and blood flow capacity were estimated. We compared the results with the control group consisted of 15 patients operated on because of chronic otitis. We confirmed a neck dissection operation influence into cranial and cervical blood flow disturbances as well as relationship between postoperative soft tissue oedema and hemodynamical changes. We didn't found connections between cervical and cerebral blood flow and postoperative complications.
