Complicaciones de las endoprótesis metálicas autoexpandibles en la obstrucción maligna esofágica y gastroduodenal. Estudio de seis casos

Abstract

The changes of coagulation parameters in preoperative fracture patients reflect the coagulation status before surgery. We did retrospective assessment of preoperative fracture patients (n = 113) admitted to the hospital between September 2013 and September 2014. The control group were selected from healthy adults (n = 113) with matched age and gender. Platelet, PT INR, APTT, fibrinogen (FIB) and D-dimer values were collected and analyzed. PT INR level was 1.043 +/- 0.119, APTT was 31.91 +/- 7.56 s, FIB was 320.6 +/- 71.8 mg/dl and D-dimer was 1283 +/- 1582 ng/ml for the fracture patients. For the control group, PT INR level was 0.9976 +/- 0.0602, APTT was 33.22 +/- 2.55 s, FIB was 277.3 +/- 44.7 mg/dl and D-dimer was 97.53 +/- 63.90 ng/ml. Meanwhile, D-dimer levels of different sites of fractures were also measured: Femora 2448 +/- 1961 ng/ml; Humerus 792.4 +/- 691.2 ng/ml; Ulna/Radius 619.4 +/- 843.7 ng/ml; Vertebra 647.7 +/- 787.1 ng/ml; Tibia/Fibula 496.3 +/- 268.8 ng/ml; Clavicle 260.9 +/- 170.9 ng/ml; Ankle 415.4 +/- 286.6 ng/ml. To conclude, D-dimer and fibrinogen levels get higher in preoperative fracture patients than controls. Besides, D-dimer levels are significantly different among different locations of fractures, and our data revealed that D-dimer levels of Femora fracture were higher than other sites.
