Risk factors for deep venous thrombosis of lower limbs in postoperative neurosurgical patients

Objectives: To detect the risk factors for deep venous thrombosis [DVT] in patients after neurosurgery

Methods:Three hundred and seventy-six patients treated in the department of neurosurgery of our hospital from February 2013 to November 2015 were reviewed retrospectively. The clinical data including age, gender, hospital stay, operation time, occupation type, hypertension, coronary heart disease, diabetes, smoking status, drinking status, postoperative exercises, malignant tumor, and postoperative hormone or dehydrating agent were collected

Results:In this study, 52 patients were included in the DVT group and 295 patients in the Non-DVT group. There was significant difference in age, hypertension, occupation type, malignant tumors, operation time, smoking status, and postoperative exercises between the two groups [p<0.05]. However, there was no significant difference in gender, drinking status, coronary heart disease, diabetes, hospital stay, and postoperative hormone or dehydrating agent [p>0.05]. In multivariate analysis, age, malignant tumor, hypertension were independent risk factors, while physical labour and postoperative exercises were protective factor for DVT

Conclusion:The postoperative patients with older age, malignant tumor or hypertension should be paid high attention to prevent DVT, and postoperative exercises should be selected as precautionary measures

Percutaneous transluminal angioplasty for the treatment of diabetic foot / 中华普通外科杂志

Objective To evaluate percutaneous transluminal angioplasty ( PTA) for stenosed arteries of the lower extremities in patients with ischaemic diabetic foot. Methods We retrospectively analyzed the clinical and follow-up data of using PTA to treat diseased infrapopliteal arteries in diabetic patients who were hospitalized from Oct,2006 to May,2008. Results Technical success rate was 87% , procedure related complications developed in 8. 9% of patients, postoperative complications were 11. 1% , perioperative mortality was 2. 5% , limb salvage rate was 90% , pain symptom was significantly mitigated or relieved, ulcer healed well. The median hospitalstay was 10 days. Restenosis rates were 38. 1 % , 50% respectively at 1 year and 2 years. Rest pain and ulcer recurrence rates were 10% and 12% at 1 year and 2 years respectively; Amputation rates were 10% and 15. 3% at 1 year and 2 years. Restenosis ( or occlusion) , rest pain or ulcer recurrence and amputation rate in Fontain Ⅳ group is significantly poorer than that in Fontain Ⅰ - Ⅲ group (P ＜0. 05). Conclusions Percutaneous transluminal angioplasty (PTA) for critical limb ischeamia in patients with ischaemic diabetic foot are feasible, with minimal invasiveness, low complications. Fontain classification predicts PTA thrapeutic results.
