脑血流图检测用于颈动脉切除术

Reoencephalography (REG) Test Being Used for Carotid Resection

颈动脉切除术的死亡率高达10～60％,故本术能否成功,和大脑侧支循环的建立至关重要。目前的预测侧支循环的方法均欠精确,Matas法虽为侧支循环的建立,奠定了有利基础,但仅凭病人感觉来判断其结果,显然极不可靠。脑血流图用于配合外科手术尚未见报道,我院自1979年将脑血流图检测与颈动脉压迫锻炼相结合,术前预测侧支循环建立的情况、能对手术起到保驾作用、术后监护,尤是手术成功的关键。本组15例手术,均获成功,因此,我们认为此法安全、简便、无创伤、可动态观察,用于颈动脉切除术准确可靠,值得推荐。

The uneventfulness of (arotid artery resection depends upon the adequacy of the callateral arterial blood supply. Clinically the operative mortality after unilateral carotid artery resection is usually from 10% to 60%. Until recently there is yet no satisfactory methods in predicting the status of the collateral arterial cross-flow. Matas test is useful in assessment of the establishment of the blood cross-flow, but it depends mainly dn the patient's subjective feeling and lacks objective criteria. Since 1979, REG has been practised by the authors with the aim of assessing cerebral cross-flow of blood supply in patients who were to undergo carotid resection. Before operation REG test was performed in association with the Matas exercise in order to establish the cerebral collateral circulation. During operation, the patient was monitored by REG to ensure patients'safety. Postoperatively REG was used to monitor the patient. To our opinion REG has been of the greatest value to a successful carotid artery resection. All 15 consecutive patients who underwent unilateral carotid resection survived the operation well.
