ObjectiveTo explore the correlation between the Barthel index score and other factors with the preoperative occurrence of deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty (THA) revision surgery. MethodsA retrospective analysis was conducted on clinical data from 122 patients who met the inclusion criteria and underwent THA revision surgery between April 2017 and November 2020. Among them, 61 were male and 61 were female, with an age range of 32-85 years (mean, 65.3 years). The reasons for revision included prosthetic joint infection in 7 cases, periprosthetic fracture in 4 cases, prosthetic dislocation in 6 cases, and aseptic loosening in 105 cases. The Barthel index score was 76.4±17.7, with 10 cases classified as level 1, 57 as level 2, 37 as level 3, and 18 as level 4. Univariate analysis was performed on variables such as age, gender, body mass index, Barthel index score, preoperative D-dimer positivity, history of diabetes, hypertension, cancer, cerebral infarction, smoking, and thrombosis in patients with and without preoperative DVT. Furthermore, logistic regression was used to identify risk factors for preoperative DVT in THA revision surgery. The incidence of preoperative DVT was compared among different Barthel index score groups. ResultsPreoperative DVT was detected in 11 patients (9.02%), all of whom had intermuscular venous thrombosis. Among them, 1 had prosthetic joint infection, 1 had periprosthetic fracture, 1 had prosthetic dislocation, and 8 had aseptic loosening. Univariate analysis showed significant differences between the two groups in terms of age, gender, and Barthel index score (P<0.05). logistic regression further revealed that female, age ≥70 years, and Barthel index score<60 were independent risk factors for preoperative DVT in patients undergoing THA revision surgery (P<0.05). The incidence of preoperative DVT in patients with Barthel index scores of levels 1, 2, 3, and 4 were 0 case (0%), 2 cases (3.5%), 3 cases (8.1%), and 6 cases (33.3%), respectively. A significant correlation was found between Barthel index score classification and the incidence of preoperative DVT in patients undergoing THA revision surgery (χ2=10.843, P=0.001). ConclusionIn patients undergoing THA revision surgery, older age, female, and lower Barthel index scores are associated with higher preoperative DVT incidence. For patients with low preoperative Barthel index scores, preoperative thrombosis screening should be emphasized.
Objective To improve the knowledge of inflammatory bowel disease complicated with venous thromboembolism for better diagnosis and treatment. Methods One case of patient with ulcerative colitis complicated with a multiple vessel thromboembolism ( pulmonary arterial, deep vein of lower limb, and superior mesenteric vein) was analyzed, and related literatures were reviewed. Results The patient resulted in pulmonary thromboembolism ( PTE) recurrence because of irregular treatment. In addition to deep vein thrombosis of the lower extremity, a new discovery of the superior mesenteric vein embolism ( MVT) was diagnosed. The bleeding risk of heparin or lowmolecular weight heparin ( LMWH) for treatment is low, while that of warfarin is high. Conclusions Venous thromboembolism ( VTE) has a close relationship with inflammatory bowel disease ( IBD) such as ulcerative colitis. The symptomis not so typical that it is easy to misdiagnosis and missed diagnosis. It is noted that mesenteric venous thrombosis ( MVT) should be excluded in IBD patients suffering from VTE, if the source of embolus is not clear. Suitable treatment should be considered according to the risk stratification of VTE and risk-benefit ratio because of a high bleeding risk.
Objective To establish and validate a risk prediction model for post-thrombotic syndrome (PTS) in patients after interventional treatment for acute lower extremity deep vein thrombosis (LEDVT). MethodsA retrospective study was conducted to collect data from 234 patients with acute LEDVT who underwent interventional treatment at Xuzhou Central Hospital from December 2017 to June 2022, serving as the modeling set. Factors influencing the occurrence of PTS were analyzed, and a nomogram was developed. An additional 98 patients from the same period treated at the Xuzhou Cancer Hospital were included as an external validation set to assess the reliability of the model. ResultsAmong the patients used to establish the model, the incidence of PTS was 25.2% (59/234), while in the validation set was 31.6% (31/98). Multivariate logistic regression analysis of the modeling set identified the following factors as influencing PTS: age (OR=1.076, P=0.001), BMI (OR=1.163, P=0.004), iliac vein stent placement (OR=0.165, P<0.001), history of varicose veins (OR=5.809, P<0.001), and preoperative D-dimer level (OR=1.341, P<0.001). These 5 factors were used to construct the risk prediction model. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was 0.869 [95%CI (0.819, 0.919)], with the highest Youden index of 0.568, corresponding to a sensitivity of 79.7% and specificity of 77.1%. When applied to the validation set, the AUC was 0.821 [95%CI (0.734, 0.909)], with sensitivity of 77.4%, specificity of 76.1%, and accuracy of 76.6%. ConclusionsThe risk prediction model for PTS established in this study demonstrates good predictive performance. The included parameters are simple and practical, providing a useful reference for clinicians in the preliminary screening of high-risk PTS patients.
Objective To explore the impact of anemia on the incidence of perioperative lower limb deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty (THA). Methods A retrospective analysis was conducted on clinical data of 1 916 non-fracture patients who underwent THA between September 2015 and December 2021, meeting the selection criteria. Among them, there were 811 male and 1 105 female patients, aged between 18 and 94 years with an average of 59.2 years. Among the patients, 213 were diagnosed with anemia, while 1 703 were not. Preoperative DVT was observed in 55 patients, while 1 861 patients did not have DVT preoperatively (of which 75 patients developed new-onset DVT postoperatively). Univariate analysis was performed on variables including age, gender, body mass index (BMI), diabetes, hypertension, history of tumors, history of thrombosis, history of smoking, revision surgery, preoperative D-dimer positivity (≥0.5 mg/L), presence of anemia, operation time, intraoperative blood loss, transfusion requirement, and pre- and post-operative levels of red blood cells, hemoglobin, hematocrit, and platelets. Furthermore, logistic regression was utilized for multivariate analysis to identify risk factors associated with DVT formation. Results Univariate analysis showed that age, gender, hypertension, revision surgery, preoperative levels of red blood cells, preoperative hemoglobin, preoperative D-dimer positivity, and anemia were influencing factors for preoperative DVT (P<0.05). Further logistic regression analysis indicated that age (>60 years old), female, preoperative D-dimer positivity, and anemia were risk factors for preoperative DVT (P<0.05). Univariate analysis also revealed that age, female, revision surgery, preoperative D-dimer positivity, anemia, transfusion requirement, postoperative level of red blood cells, and postoperative hemoglobin level were influencing factors for postoperative new-onset DVT (P<0.05). Further logistic regression analysis indicated that age (>60 years old), female, and revision surgery were risk factors for postoperative new-onset DVT (P<0.05). Conclusion The incidence of anemia is higher among patients with preoperative DVT for THA, and anemia is an independent risk factor for preoperative DVT occurrence in THA. While anemia may not be an independent risk factor for THA postoperative new-onset DVT, the incidence of anemia is higher among patients with postoperative new-onset DVT.
Objective To investigate the short-term result of catheter directed thrombolysis (CDT) in treatment of acute deep venous thrombosis (DVT) in lower extremity. Methods A total of 289 cases of acute DVT in lower extremity who got treatment in Nanjing Drum Tower Hospital Group Suqian City People’s Hospital and Xuzhou Central Hospital from March 2013 to December 2014 were enrolled prospectively, and of them, 125 cases of system thrombolysis (ST) group underwent ST, 164 cases of CDT group underwent inferior vena cava filter placement (IVCF)+CDT. Clinical effect was compared between the 2 groups. Results Clinical symptoms of all cases were obviously relieved, and limb swelling was significantly reduced. Of the CDT group, 73 cases presented iliac vein compression syndrome (IVCS), and 43 cases of them underwent the percutaneous transluminal angioplasty and stent implantation. In CDT group, there was 1 case complicated by catheter displacement, 10 cases suffered from puncture site ecchymosis, 3 cases suffered from hematuria. In ST group, there was 1 case suffered from pulmonary embolism (PE), 14 cases suffered from bleeding gums, 22 cases suffered from hematuria, 3 cases suffered from skin and mucosa petechia, and 2 cases suffered from melena (didn’t need transfusion). The morbidity of ST group was higher than that of CDT group (P=0.002). There were 18 cases suffered from recurrence in ST group, 15 cases suffered from recurrence in CDT group, but there was no significant difference in the recurrence rate between the 2 groups (P=0.786). In addition, the dosage of urokinase, thrombolysis time, blood vessel patency score, thigh circumference after treatment, and calf circumference after treatment in ST group were all higher than those of CDT group (P<0.050), but the Villalta score in ST group was lower than that of CDT group (P<0.001). There was no significant difference in hospital stay (P=0.383). Conclusion For acute DVT in lower extremity, CDT has a superior short-term outcome with safety and feasibility.
ObjectiveTo investigate the incidence of perioperative deep venous thrombosis (DVT) of lower extremities and its risk factors in elderly patients with femoral neck fracture. Methods The clinical data of 4 109 elderly patients with femoral neck fracture admitted between August 2012 and November 2020 and met the selection criteria were retrospectively analyzed. Among them, there were 1 137 males and 2 972 females; their ages ranged from 65 to 101 years, with an average of 77.0 years. The time from fracture to admission ranged from 1 to 360 hours, with an average of 35.2 hours. There were 1 858 cases of hemiarthroplasty, 1 617 cases of total hip arthroplasty, and 634 cases of internal fixation surgery. The preoperative age-adjusted Charlson comorbidity index (aCCI) was 4 (3, 5). Perioperative DVT occurred in 857 cases (20.9%). Univariate analysis was performed on age, gender, body mass index, fracture side, time from fracture to admission, operation type, anesthesia type, blood transfusion, blood pressure after admission, and preoperative aCCI in patients with and without perioperative DVT, and logistic regression analysis was used to screen the risk factors of perioperative DVT in elderly patients with femoral neck fracture. ResultsUnivariate analysis showed that there were significant differences in age, gender, time from fracture to admission, operation type, and preoperative aCCI between the two groups (P<0.05). Further logistic regression analysis showed that age>75 years, female patients, time from fracture to admission>24 hours, and preoperative aCCI>5 were risk factors for perioperative DVT (P<0.05). Conclusion Elderly patients with femoral neck fracture have a higher incidence of perioperative DVT. The advanced aged and female patients, patients with longer fracture time and more comorbidities need to pay special attention to the prevention of perioperative DVT to minimize the occurrence of DVT during femoral neck fractures.
ObjectiveTo evaluate the value of clinical application of determination of lower venous pressure in the diagnosis and treatment of deep venous thrombosis (DVT). MethodsThe 90 patients with DVT of unilateral lower limb who were admitted by using color Doppler or deep veins of lower limb angiography in our hospital during the period of 2013 July to 2014 June were selected and as the research object (case group), 37 cases were male, 53 cases were female; the age was 18-84 years old, mean age was 59.48 years old. According to the development of disease, 90 cases were divided into acute 30 cases, subacute 30 cases, and chronic 30 cases; and according to the pathological types were divided into the central type in 30 cases, 30 cases of peripheral type, and 30 cases of mixed type. At the same time the without lower extremity DVT volunteers of 20 cases were selected as normal control group, including male 9 cases, female 11 cases; age was 21-65 years old, average age was 38.7 years old. The static venous pressure (P0), dynamic venous pressure (P00), and decreased pressure ratio (Pd) of double lower limbs of participants in 2 groups were determinated and comparative analyzed. ResultsThe P0 and P00 of patients with different development of disease and pathological types of the case group were higher than those of the normal control group (P < 0.01), and the Pd was lower than that of the normal control group (P < 0.01). In case group, the P0 and P00 of acute phase were higher than those of the normal control group (P < 0.01), the P0 of central type was higher than that of the peripheral type and mixed type (P < 0.01), and the Pd central type was lower than that of mixed type (P < 0.01). The above 3 indexes' differences of double lower limbs in the normal control group had no statistical significance (P > 0.01). In case group, the P0 and P00 of ipsilateral limb in different development of disease and pathological types were higher than those of the healthy limb, and the Pd were lower than that of the healthy limb (P < 0.01). ConclusionsLower extremity venous pressure measurements can be used in clinical detection for early lower limb DVT, and can be used as the objective index of clinical evaluation curative effect for the treatment of DVT. It is a simple and practical clinical detection method.
ObjectiveTo summarize the experience of treating lower extremity deep venous thrombosis (DVT) after repair of inguinal hernia. MethodThe clinical data of 1 812 patients who underwent herniorrhaphy from January 2002 to December 2012 were reviewed, and we analyzed such data as age, gender, and the formation of DVT. ResultsFive of them suffered from DVT (0.28%), including 2 cases involving both lower extremities, 1 right and 2 left extremity. All of them were discharged from hospital by anticoagulant therapy and there was no pulmonary embolism and death case. DVT recovered well in 4 cases half a year after being discharged from the hospital. One had a sequela of recurrent swelling of the left lower extremity. ConclusionsReasonable precautions and treatment against DVT are very important even though DVT rate after inguinal hernia repair is low.
ObjectiveTo explore the value of potaried technique with Trivex system in treatment for venous skin ulcer with deep venous thrombosis sequelae (DVTS) of lower limbs. MethodsTotal 166 patients with venous skin ulcer with DVTS of lower limbs were included in this study. The patients of operation group (94 patients involving 94 legs) were treated by using potaried technique with Trivex system. The patients of nonoperation group (72 patients involving 72 legs) were treated by using nonoperative method. The clinical indexes of skin infection rate, skin necrosis rate, shrinkage rate of wound area, skin depigmentation rate, ulcer healing rate and ulcer recurrence rate were used to assess the clinical curative effect between two groups on 5, 20, 120 and 360 d after operation or treatment, respectively. ResultsThere were no skin infection and skin necrosis in two groups on 5 d after operation or treatment. The rate of shrinkage of wound area and skin depigmentation of patients in operation group were significantly higher than those in nonoperation group on 20 d after operation or treatment 〔(95.8±2.138)% vs. (68.7±3.125)%，P=0.048; (87.6±1.263)% vs. (12.3±1.324)%， P=0.018〕. The rate of the ulcer healing of patients in operation group was significantly higher than that in nonoperation group on 120 d after operation or treatment (97.9%vs. 8.3%， P=0.014). The rate of the ulcer recurrence of patients in operation group was significantly lower than that in nonoperation group on 360 d after operation or treatment (5.3% vs. 97.2%， P=0.015). ConclusionThe potaried technique with Trivex system can be used as one of the surgical treatment methods for venous skin ulcer with DVTS of lower limbs.
