To reduce saline and heparin in continuous catheter perfusion in intraoperative cerebral angiography, a method using a syringe pump was tried.
Ten patients with brain arteriovenous malformation (AVM) underwent intraoperative cerebral angiography. Seven internal carotid arteries (ICAs) and six vertebral arteries (VAs) were catheterized in these patients. Continuous catheter perfusion was performed at a low rate of 3 mL/hr with saline containing 8,000 units of heparin per liter using a syringepump.
Mean duration of catheter perfusion was 8.3 +/- 4.0 hrs (range, 3.0 to 15.7 hrs). Mean volume of saline was 25.0 +/- 11.9 mL (range, 9 to 47 mL) per catheter. Mean dosage of heparin was 200.0 +/- 94.9 units (range, 72 to 376 units) per catheter. No complications due to intraoperative angiography were observed in this trial.
Reduction of the saline volume and heparin dosage was possible in intraoperative cerebral angiography by the continuous perfusion of a small amount of high-concentration heparinized saline using a syringe pump.
为减少术中脑血管造影连续导管灌注时的生理盐水和肝素用量，尝试了一种使用注射泵的方法。
10例脑动静脉畸形（AVM）患者接受了术中脑血管造影。这些患者共插入了7条颈内动脉（ICA）和6条椎动脉（VA）。使用注射泵以3 mL/小时的低速率对含每升8000单位肝素的生理盐水进行连续导管灌注。
导管灌注的平均持续时间为8.3±4.0小时（范围为3.0至15.7小时）。每条导管的生理盐水平均用量为25.0±11.9 mL（范围为9至47 mL）。每条导管的肝素平均用量为200.0±94.9单位（范围为72至376单位）。本试验未观察到因术中血管造影引起的并发症。
在术中脑血管造影中，通过使用注射泵连续灌注少量高浓度肝素化生理盐水，可以减少生理盐水用量和肝素剂量。
