UNASSIGNED: A prospective observational study was performed. During the endovascular revascularization procedure, tissue oxygenation changes were measured using three NIRS sensors. Postoperative angiographies and 30 days wound healing was evaluated.
UNASSIGNED: The study enrolled 30 patients with chronic limb threatening ischemia, occluded below the knee arteries, Rutherford 5. Mean age 74.7 ± 11.2 years, 16 (53%) of the patients had diabetes mellitus, 10 (33%) had end-stage renal disease. A statistically significant NIRS rSO 2 increase was observed on sensors near the wound after the revascularization, p = 0.001. Thirty days follow-up visits included 27 patients, because 3 patients had died. Comparing good wound healing group with poor wound healing group intraoperative NIRS rSO 2 increase difference was statistically significant, p = 0.017.
UNASSIGNED: The study confirmed tissue perfusion increase could be detected using NIRS during revascularization of below the knee arteries. An intraoperative increase of NIRS rSO 2 proved to predict wound healing results.
■进行了一项前瞻性观察性研究。在血管内血运重建过程中,使用三个NIRS传感器测量组织氧合变化.评估术后血管造影和30天伤口愈合。
■该研究纳入了30例慢性威胁肢体缺血患者,阻塞在膝盖动脉以下,卢瑟福5号.平均年龄74.7±11.2岁,16例(53%)患者患有糖尿病,10例(33%)有终末期肾病。血运重建后,在伤口附近的传感器上观察到有统计学意义的NIRSrSO2增加,p=0.001。30天的随访包括27名患者,因为3名患者死亡。比较伤口愈合良好组与伤口愈合不良组术中NIRSrSO2升高差异有统计学意义,p=0.017。
■该研究证实,在膝下动脉血运重建过程中,NIRS可检测到组织灌注增加。术中NIRSrSO2的增加被证明可以预测伤口愈合的结果。
