The Special Correlation Factors For Early Deep Venous Thrombosis After Spine Surgery

Background: Deep vein thrombosis(DVT) is a serious complication oforthopedic postoperative patients. It is the Important reason for disability anddeath in patients with pulmonary embolism (PE) secondary to the DVT.Currently, the researches about DVT after the lower extremity fractures andarthroplasty such as incidence, risk factors, prevention and treatment have lotsof reports and have formed a relatively standardized preoperative andpostoperative prevention programs. With the development of spinal surgery, itis increasing year by year, and DVT have occurred from time to time.Therefore, more and more attentions have benn paid to it. The study about DVTafter spinal surgery is increasing overseas, but the internal report of theincidence and relevant factors about this kind of disease is seldom, what’smore,it is mostly retrospective and a more general study and lack of a largenumber of more specific forward-lookingstudysObjective: The aim of this article is to observe the spinal patients withearly DVT after spinal surgery, and mostly analyze the special relevant factorsand the risk of DVT, not the common factors by which many other diseasesalso can be complicated. It will prevent more relevance and feasibility proposalfor the prevention of the DVTMethod: A total of166consecutive and independent samples of spinalsurgery patients in the First Hosptital of JiLin University from June2011~November2011. Type-B ultrasonic were examined in these patients, andclassify these cases into two groups, group complicated with DVT and groupwithout DVT according to muscle strength, trauma, lower limb vasomotor dysfunction, physical cooling, implants, surgical position, dehydration drug,postoperative bed time, the use of braces, the use of lower limbs afterthrombolytic therapy instrument and lower limbs exercise. All factors wereanalyzed by Logistic multi-factor regression analysis using SPSS18.0statisticssoftware.Result: There were166cases of spinal disease, male108cases,58casesof women, aged19to77years,and an average of47.8years. Early concurrentDVT18cases, not concurrent DVT148cases, and the risk of DVT after thespinal surgery is10.8%in my department. All thrombuses located in the calf,including13cases in calf myenteric vein,2cases in anterior tibial vein, and3cases in both peroneal veins of calf and posterior tibial vein. There were4symptomatic patients (2.4%),14asymptomatic patients (8.4%), no patient withpulmonary embolism. Muscle abnormalities and traumatic spinal postoperativewere the risk factors of DVT, and their P values were0.001and0.002(P <0.05),and no protective factors were found. Other factors include lower limbvasomotor dysfunction, physical cooling, implants, surgical position,dehydration drug, postoperative bed time, the use of braces, the use of lowerlimbs after thrombolytic therapy instrument and lower limbs exercise, their Pvalue wer0.343,0.296,/,0.656,0.952,0.730,0.967and0.263(P>0.05).The above factors does not exist a statistically significant difference in the DVTgroup and non-DVT group,and they can not constitute the risk and theprotective factors of DVT after spinal surgery.Conclusion:1.The incidence of DVT after spine surgery is high, UP to10.8%.2. Muscle abnormalities and traumatic spinal postoperative were therisk factors of DVT.3. The spinal patients with DVT are mostly asymptomatic.4. Vascular ultrasound can help to reduce the rate of misdiagnosis of DVT.5. We should pay attention to the prevention of DVT and carry out theindividualized treatment for the patients with DVT.
