Objective To identify the risk factors for coagulopathy after Stanford type A acute aortic dissection (AAD) repair to offer evidence for improvement of patients' prognosis. Methods We retrospectively analyzed the clinical data of 95 patients undergoing Stanford type A AAD repair in Beijing Anzhen Hospital between January 2013 and December 2014. Patients with thromboelastography-coagulation index (TEG-CI) ≤–3 after surgery were allocated to a coagulopathy group (n=17, average age 48.70 years), whereas patients with TEG-CI >–3 after surgery were allocated to a control group ( n=78, average age 46.80 years). Multivariate analysis was used to identify risk factors for coagulopathy after surgery. Results Seventeen patients suffered from coagulopathy after surgery. Patients in the coagulopathy group had larger amount of fluid drainage than that in the control group (P=0.008). Risk factors for postoperative coagulopathy were activated partial thromboplastin time (APTT) at the end of surgery ( OR=0.011, 95% confidence interval 0.001 to 0.021, P=0.035), fibrinogen degradation products (FDP) at the end of surgery (OR=0.004, 95% confidence interval 0.001 to 0.007, P=0.022) and platelet count (×109/L) at the end of surgery (OR=–0.002, 95% confidence interval –0.003 to 0.000, P=0.049). The lower risk of postoperative coagulopathy was related to the platelet count at the end of surgery up to 137.00 ×109/L. Conclusion Postoperative coagulopathy could be related to the clinical and experimental variables. In a representative sample of Chinese adults undergoing Stanford type A AAD surgery, APTT, FDP and platelet count at the end of surgery are independent risk factors associated with postoperative coagulopathy. Adding haemostatic, such as fibrinogen and prothrombinase complex, is good for improving the recovery of coagulation function to reduce bleeding and postoperative blood transfusion, as well as adding platelet, plasma and other coagulation factors after AAD surgery.
Objective To explore the surgical method and effectiveness of multi-spot suture fixation under arthroscope in treating tibial intercondylar anterior eminence fracture. Methods Between February 2006 and January 2010, 15 patients with tibial intercondylar anterior eminence fracture were treated with multi-spot suture fixation under arthroscope after fracture reduction. There were 14 males and 1 female with a median age of 33 years (range, 7-55 years). The injury causeswere traffic accident in 9 cases, sport in 2 cases, and fall ing in 4 cases. The anterior drawer test, Lachman test, and pivot shift test in all the cases turned out to be positive. The Lysholm score was 64.7 ± 1.3. According to Meyers-McKeever classification, 5 cases were classified as type II, 7 cases as type III, and 3 cases as type IV. Of them, 13 cases had fresh fracture and 2 cases had old fracture. Assisted with anterior cruciate l igament-aimer, bone tunnels (2 mm in diameter) were built through the fracture fragments after fracture reduction, through which Ethibond 2 polyester sutures were guided into the joint by No.18 spine needles; after knot of 2 sutures or knot of only 1 suture was made, the other ends of sutures were fastened together outside the joint. Results The incisions of all the cases healed by first intention with no compl ication of infection or deep venous thrombosis. Fifteen patients were followed up 14-48 months with an average of 24.2 months. The X-ray examination indicated fractures healed in all the cases at 2-4 months (mean, 3 months). At 6 months after operation, 14 cases showed negative results of Lachman test and anterior drawer test but 1 case positive, while all the cases showed negative results in pivot shift test. The extension and flexion spheres of knee activity were normal in 13 cases and were l imited in 2 cases. The Lysholm score was 95.1 ± 2.1, showing significant difference when compared with the preoperative score (t=43.020, P=0.000). Conclusion Multi-spot suture fixation under arthroscope is an effective method with small invasion, rel iable fixation, and simple operation for treating tibial intercondylar anterior eminence fracture.
