Lower Extremity Arteriovenous Fistula Mimicking Deep Venous Thrombosis: A Case Report

Objective To compare the therapeutic effects of ultrasound-guided and non-guided catheter-directed thrombolysis in the treatment of deep venous thrombosis of lower extremity. Methods From August 2015 to April 2016, 60 patients with lower extremity deep venous thrombosis were randomly divided into two groups ( n = 30 for each) to receive catheter-directed thrombolysis. Group A was treated under the ultrasound guidance, while Group B was treated without guidance. Results Catheter-directed thrombolysis was successfully performed by only one intubate in Group A but by 5.9 intubates in Group B. It took 15.4 ± 3.2 min in Group A, significantly less than that in Group B (30.8 ± 6.6 min, p < 0.05). The incidences of hematoma were also remarkably different between the two groups (3.33% vs. 26.67%, p = 0.026). No pseudoaneurysm or arteriovenous fistula was found in Group A, but there were two cases of pseudoaneurysm and two cases of arteriovenous fistula in Group B (both 6.67%, p = 0.492). The circumference differences of the affected limb between before and after thrombolysis were 49.47 ± 2.484 mm in Group A, significantly higher than that in Group B (28.40 ± 2.856 mm, p < 0.001). After treatment, the venous unobstructed improvement rates and deep vein patency rate were both better than those in Group B (77 + 2.603% vs. 57.23 + 1.828% and 80% vs. 46.67%, respectively; p < 0.001). There were only three cases of PTS in Group A (10%, 3/30), but there were 11 cases in Group B (36.67%, 11/30). Conclusion Ultrasound-guided catheter-directed thrombolysis has advantages, with improvement of venous patency and decrease of the incidence of PTS.

Common Diagnosis

Introduction: Lower extremity deep venous thrombosis (DVT) is a common diagnosis in the emergency department (ED). Deep venous thromboses can be the result of anatomical variation in the vasculature that predisposes the patient to thrombosis. May-Thurner syndrome (MTS) is one such anatomic variant defined by extrinsic compression of the left common iliac vein between the right common iliac artery and lumbar vertebrae. Case Report: We report such a case of a 39-year-old woman with no risk factors for thromboembolic disease who presented to the ED with extensive unilateral leg swelling and was ultimately diagnosed with MTS. Conclusion: This diagnosis is an important consideration particularly in patients who are young, female, have scoliosis or spinal abnormalities, or are at low risk for DVT yet who present with extensive lower extremity swelling and are found to have proximal thrombus burden. Often further imaging, anticoagulation, angioplasty, or thrombectomy are indicated to prevent morbidity and post-thrombotic syndrome in these patients.

Abstract Background Limited information exists on the incidence of postoperative deep venous thromboembolism (DVT) in patients with isolated patella fractures. The objective of this study was to investigate the postoperative incidence and locations of deep venous thrombosis (DVT) of the lower extremity in patients who underwent isolated patella fractures and identify the associated risk factors. Methods Medical data of 716 hospitalized patients was collected. The patients had acute isolated patella fractures and were admitted at the 3rd Hospital of Hebei Medical University between January 1, 2016, and February 31, 2019. All patients met the inclusion criteria. Medical data was collected using the inpatient record system, which included the patient demographics, patient’s bad hobbies, comorbidities, past medical history, fracture and surgery-related factors, hematological biomarkers, total hospital stay, and preoperative stay. Doppler examination was conducted for the diagnosis of DVT. Univariate analyses and multivariate logistic regression analyses were used to identify the independent risk factors. Results Among the 716 patients, DVT was confirmed in 29 cases, indicating an incidence of 4.1%. DVT involved bilateral limbs (injured and uninjured) in one patient (3.4%). DVT involved superficial femoral common vein in 1 case (3.4%), popliteal vein in 6 cases (20.7%), posterior tibial vein in 11 cases (37.9%), and peroneal vein in 11 cases (37.9%). The median of the interval between surgery and diagnosis of DVT was 4.0 days (range, 1.0-8.0 days). Six variables were identified to be independent risk factors for DVT which included age category (> 65 years old), OR, 4.44 (1.34-14.71); arrhythmia, OR, 4.41 (1.20-16.15); intra-operative blood loss, OR, 1.01 (1.00-1.02); preoperative stay (delay of each day), OR, 1.43 (1.15-1.78); surgical duration, OR, 1.04 (1.03-1.06); LDL-C (> 3.37 mmol/L), OR, 2.98 (1.14-7.76). Conclusion Incidence of postoperative DVT in patients with isolated patella fractures is substantial. More attentions should be paid on postoperative DVT prophylaxis in patients with isolated patella fractures. Identification of associated risk factors can help clinicians recognize the risk population, assess the risk of DVT, and develop personalized prophylaxis strategies.
