FIELD: medicine, neurosurgery. ^ SUBSTANCE: one should measure blood pressure in afferent vessel of cerebral arteriovenous malformation (AVM). If measured pressure is above that of functionally insignificant vessel being 25% against systemic arterial pressure for AVM at blood flow of 1000 ml/min and 50% for AVM at blood flow of 500 ml/min one should conclude the vessel to be functionally valuable. The method enables to decrease complications due to increased reliability in detecting functional value of ABM-supplying vessels. ^ EFFECT: higher efficiency of detection. ^ 1 ex |
