The correlation between intraoperative pressure levels measured in the feeding arteries and in the draining veins, and the risk of hemorrhage from arteriovenous malformations (AVMs) is discussed. Feeding artery pressure (FAP) was significantly higher in AVMs with hemorrhage (57 +/- 11 mmHg) than in AVMs without hemorrhage (38 +/- 4), and draining vein pressure (DVP) in the former (24 +/- 5) was significantly higher than that in the latter (13 +/- 5). FAP and DVP were inversely related to the number of draining veins and size of the AVMs. The present study suggests that a high FAP and a high DVP may contribute to the development of hemorrhage from AVMs, and supports previous reports that small AVMs and AVMs with only one draining vein are susceptible to hemorrhage.
探讨了在供血动脉和引流静脉中测量的术中压力水平与动静脉畸形（AVM）出血风险之间的相关性。有出血的AVM的供血动脉压力（FAP）（57±11 mmHg）显著高于无出血的AVM（38±4），前者的引流静脉压力（DVP）（24±5）也显著高于后者（13±5）。FAP和DVP与引流静脉数量及AVM大小呈负相关。本研究表明，高FAP和高DVP可能促成AVM出血的发生，并支持先前的报道，即小型AVM和仅有一条引流静脉的AVM易发生出血。
