Clinical Analysis Of 88 Cases Of Superior Mesenteric Vein Thrombosis

Objective: To investigate the clinical characteristics and diagnosis and treatment of superior mesenteric vein thrombosis(SMVT).Methods: The clinical data of 88 cases of SMVT diagnosed in our hospital from January 2006 to December 2016 were analyzed retrospectively.The effects of different treatment methods and timing of operation on the prognosis of patients were analyzed.According to the presence of intestinal infarction,56 cases of SMVT-induced intestinal necrosis were confirmed by operation,and the remaining 56 cases of SMVT were taken as control group.The clinical indexes,laboratory tests and radiographic examination were used to calculate the SMVT,and the influencing factors were included in the multivariate logistic to evaluate the relationship between SMVT-induced intestinal necrosis and clinical risk factors,and to establish a logistic predictive model to evaluate the accuracy,sensitivity and specificity of predicting intestinal necrosis caused by SMVT.Results: Of the 88 patients with SMVT,there were 62 males and 26 females,aged 53.4 ± 12.4 years.During hospitalization,85 deaths and 3 deaths occurred.The mortality rate was 3.5%.35 cases of abdominal surgery history,hepatitis,cirrhosis patients with 31 cases of malignant tumor history,4 cases of cardiovascular and cerebrovascular disease,3 cases of diabetes,systemic lupus erythematosus in 1 case,the remaining 11 cases were not found high risk factors.Abdominal pain for its main clinical manifestations,accounting for 99%,of which the persistence and limitations of 33%,66%.(64%,42%,33%,28%).According to different treatment methods,laparotomy group(n = 32)and interventional thrombolysis group(n = 14),all patients underwent abdominal enhanced CT treatment,divided into non-surgical group(n = 42)compared with non-surgical group,(P <0.05).The hospitalization time of the intervention group and the non-operation group was significantly higher than that of the control group(P <0.05),the difference was statistically significant(P <(P <0.05).Statistical analysis could be used as one of the early clinical treatments,according to its intensity: persistent abdominal pain,respiratory rate,intestinal edema,preoperative leukocyte level,SMVT-induced small intestinal necrosis The accuracy was 85.23% and the sensitivity was 71.88%.The specificity was 92.86%.Conclusion: The incidence of SMVT is increasing gradually.Mesenteric venous thrombosis is still mainly abdominal pain treatment.Abdominal enhanced CT can be diagnosed as a selected disease.Intravascular insertion of thrombolysis can be used as one of the early effective treatments.Continuous abdominal pain,respiratory rate,intestinal edema,preoperative leukocyte level,stool blood,preoperative pulse rate can be used as an early clinical basis for the determination of intestinal disease,intestinal necrosis,but the establishment of early laparotomy can significantly reduce bowel resection.
