Fallibility of Clinical Symptoms and Signs
2020Co-Authors: John J. Cranley, Arthur J. Canos, Won J. SullAbstract:\s=b\One hundred twenty-four patients, with 133 involved extremities having the clinical diagnosis of deep venous thrombosis of the lower extremity, were studied by phleborheography and phlebography. Seventy-two limbs were proved to have deep venous thrombosis and 61 to have no evidence of thrombi in the deep veins. Classic symptoms of muscle pain and muscle tenderness, swelling, and the presence of a positive Homans Sign obtained by dorsiflexion of the foot were found to occur with approximately equal frequency in those limbs with and without deep venous thrombosis.

Clinical, Laboratory and Echografic Evaluation of Patients with Deep Vein Thrombosis Following Total Knee Arthroplasty
Open Journal of Orthopedics, 2019Co-Authors: Carlos Roberto Schwartsmann, Mário Arthur Rockenbach Binz, Marco Tonding Ferreira, Felipe Roth, Ivan Fadanelli Simionato, Leandro De Freitas Spinelli, João Pedro Farina BrunelliAbstract:Introduction: Total knee arthroplasty, being a major surgery, carries a risk of post-operative deep vein thrombosis (DVT). The main objective of the present study was to elucidate the association of clinical, laboratory, and echographic findings with the occurrence of DVT. Patients and Methods: The present study was prospective and non-randomized, with restricted exclusion criteria. Forty patients were submitted to total knee arthroplasty due to osteoarthritis. Patients were clinically evaluated by laboratory tests, assessment of pain and calf circumference, and the presence of Homans’ Sign. Echo Doppler was performed in each patient on postoperative day 7. The echographic evaluation divided the patients into two groups: positive (G1) and negative for thrombosis (G2). All patients received prophylactic heparin during the 7-day hospital admission. Results: Eleven patients complained of pain (analgesic medication was used during the entire admission). Leg circumference variation from the pre-operative period to post-operative day 7 was: G1, 1.70 ± 1.12 cm and G2, 0.68 ± 1.25 cm (p = 0.03). Homans’ Sign was considered positive in 10 patients. Echographic evaluation was positive in 11 patients (27.5%). No cases of pulmonary embolism, infection, or death were observed. Conclusions: The incidence of DVT was 27.5%, with an increase in leg circumference being the main predictive factor (p = 0.03).

Deep vein thrombosis after total knee arthroplasty.
Journal of the Formosan Medical Association, 2000Co-Authors: Wang Cj, Wang Jw, Liming Chen, Chen Hs, Yang By, Cheng SmAbstract:Abstract The incidence of deep vein thrombosis (DVT) after total knee arthroplasty (TKA) in the Asian population is probably higher than is commonly assumed by clinicians. The purpose of this study was to investigate the incidence of DVT after TKA in a southern Taiwanese population and to determine whether routine prophylaxis against DVT is indicated. The incidence of DVT was investigated in 107 ascending venograms performed in 105 knees in 102 patients after TKA. Observations were made and interpreted by orthopedic radiologists blinded to the clinical condition of the patients. The correlation of DVT with the medical conditions, anesthesia type, and local physical findings were analyzed. The overall incidence of DVT after TKA was 63.6% (68/107); 95.6% (63/68) of cases involved the distal veins in the calf and only 4.4% (3/68) involved the proximal vein at the popliteal level. There was no higher incidence of thrombosis in the femoral and iliac veins, and no pulmonary embolism. Approximately 70% of patients with DVT were symptomatic and required treatment. There was no statistically Significant correlation of DVT with medical condition, including diabetes mellitus, hypertension, body weight, varicosity, history of thromboembolic disorder and congestive heart failure, or the type of anesthesia or bone cement used. There was a positive correlation of DVT with local physical findings including calf girth enlargement, leg edema, and skin discoloration, and a negative correlation with findings including Homans' Sign, cord induration, venous engorgement, and knee effusion. The incidence of DVT after TKA in this southern Taiwanese cohort was similar to that in Western populations, and higher than is commonly assumed by clinicians at this facility. However, the rate of proximal thrombosis and pulmonary embolism was much lower than in previous studies from Western populations. The majority of cases of DVT involved the veins in the calf; approximately 70% of patients were symptomatic and required treatment.
