Determination of the mean blood flow velocity by means of Doppler haematotachography is suggested as an aid in evaluating the haemodynamic changes associated with an intracranial arteriovenous anomaly. A Doppler haematotachogram (HTG) was obtained in 13 patients with a radiologically diagnosed arteriovenous anomaly, with marked interindividual variations in dimensions and blood supply; in 6 of these patients the Doppler HTG was obtained before and after total neurosurgical extirpation. The large majority of the patients showed a significant increase in diastolic, and to a lesser degree in systolic flow velocity at the level of the common carotid artery. In most cases the flow velocity curve of the ophthalmic artery showed a decrease in amplitude. These are the most useful parameters in evaluating the haemodynamic effect of an intracranial arteriovenous anomaly. After the surgical removal of the anomaly, the carotid flow velocity decreased significantly. In the internal and external jugular veins, Doppler-haematotachographic pulse waves were registered for the first time. These may have been conducted from the internal carotid artery to the jugular veins via the arteriovenous anomaly. The usefulness of this parameter is reduced because of the cumbersome calculations required to determine the time within which an arterial pulse wave conducted via the arteriovenous anomaly reaches the jugular vein. Registration of this unusual pulse wave is solely of theoretical value.
建议采用多普勒血流速度描记法测定平均血流速度，以辅助评估与颅内动静脉畸形相关的血流动力学变化。对13例经放射学诊断为动静脉畸形的患者进行了多普勒血流速度描记图（HTG）检查，这些患者的动静脉畸形在大小和血供方面存在明显的个体差异；其中6例患者在神经外科完全切除前后均进行了多普勒HTG检查。绝大多数患者颈总动脉水平的舒张期血流速度显著增加，收缩期血流速度增加程度较小。在大多数情况下，眼动脉的血流速度曲线振幅降低。这些是评估颅内动静脉畸形血流动力学效应最有用的参数。手术切除畸形后，颈动脉血流速度显著降低。首次在内、外颈静脉记录到多普勒血流速度描记图的脉搏波。这些脉搏波可能是通过动静脉畸形从颈内动脉传导至颈静脉的。由于确定经动静脉畸形传导的动脉脉搏波到达颈静脉的时间所需的计算繁琐，该参数的实用性降低。记录这种异常脉搏波仅具有理论价值。
