概括
在中脑动脉区域的手术前脑血管反应 (CVR) 预测了莫亚莫亚病的绕道流量需求. 较高的CVR损伤与绕道流量的增加相关,这表明当脑血管储备尚未耗尽时,STA-MCA绕道是最佳的.

Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
