全膝关节置换术（TKA）后使用止血带发生肺血栓栓塞（PTE）的风险仍有争议。在这项研究中，我们确定了血浆D-二聚体是否可以用作PTE的标志物，以及术中使用止血带是否是TKA后症状性PTE的风险因素。我们根据（i）手术方法（单侧/双侧）和（ii）术中使用充气止血带（有/无）将86例接受初次TKA的患者（12例男性和74例女性）分为4组。在术前和术后第1天测量血浆D-二聚体值。“D1值”定义为术后和术前血浆D-二聚体水平之间的差异。我们通过氧饱和度（SAT）和肺动脉造影监测，确定了症状性PTE的“D1值”临界值。有PTE症状者的D1值高于无症状者（p
The risk of pulmonary thromboembolism (PTE) after total knee arthroplasty (TKA) with, tourniquet is still controversial. In this study, we determined whether plasma D-dimer could be used, as a marker of PTE, and whether intraoperative use of tourniquet is a risk factor for symptomatic PTE after TKA. We divided 86 patients (12 mates and 74 females) who underwent primary TKA into four groups based on (i) operation method (unilateral/bilateral) and (ii) use of pneumatic tourniquet during surgery (with/without). Plasma D-dimer values were measured preoperatively and on Day 1 postoperatively. ''D1-value" was defined as the difference between postoperative and preoperative plasma D-dimer levels. We determined the cut off level of "D1-value" for symptomatic PTE, monitored by O-2 saturation (SAT) and lung scintigraphy. "D1-values" for patients with PTE symptoms were higher than those without symptoms (p
