Background: The main aim is to study the association between asymptomatic deep vein thrombosis (DVT) in patients with varicose veins in different gender and age groups. Secondly, to study the risk of developing DVT in patients having superficial venous thrombophlebitis (SVT) with varicose veins and finally to study the clinical correlation of clinical, etiological, anatomical and pathological (CEAP) classification with DVT in patients with varicose veins.Methods: Patients presenting to department of General surgery at SS Institute of Medical Science and Research Centre during the period from June 2017 to June 2019 with varicose veins of lower limbs and without clinical signs of DVT were included in this study. Patients were categorised according to CEAP classification. All patients were subjected to duplex scanning of lower limbs to look for presence of SVT and DVT.Results: In our study, 73% patients were males and 27% patients were females. Maximum patients were in age group of 40-60 years.16 patients had DVT, 38 patients had SVT, 166 patients belonged to C2 and 56 patients belonged to CEAP class C3 and beyond.Conclusions: There is a strong association between varicose veins and asymptomatic DVT .The presence of SVT is not a risk factor for concomitant DVT in varicose vein patients. Clinical presentation with C3 or more CEAP grade is one of the potential risk factors for concomitant DVT in vari­cose vein patients.

Background: Pulmonary embolism (PE) is relatively a common cardiovascular complication following acute deep vein thrombosis (DVT). Around 10% of DVT patients exhibit clinical manifestations of PE. Oral drugs with adequate efficacy and safety are preferred over parenteral medications in long term prevention of PE. Our study compared rivaroxaban (factor XA inhibitor) with standard therapy (acetrom) in terms of efficacy and safety in the Indian population.Methods: Patients presenting to department of general surgery at S. S. institute of medical science and research centre during the period from March 2018 to September 2020 with clinical signs and venous duplex study proven acute DVT were included in the study. Total of 64 patients were randomized into rivaroxaban group (N=28) and control group (N=36). Treatment included for rivaroxaban group was rivaroxaban (p/o) 15 mg twice daily for 21 days, followed by 20 mg once daily for 6 months. Treatment included for control group was enoxaparin (SC) overlapping with and followed by acitrom (p/o) for 6 months. The patients were looked for symptomatic recurrent PE and major or minor clinically relevant bleeding.Results: Recurrent vein thrombosis noted in 1 (3.57%) patient of the rivaroxaban group and 4 (11.10%) patients in the control group. Minor bleeding seen in 3 (10.70%) patients in the rivaroxaban group and in 7 (19.40%) patients in the control group. No major bleeding was observed in rivaroxaban group and in 1 patient in the control group.Conclusions: In patients with acute DVT, rivaroxaban is as efficacious as enoxaparin followed by acetram therapy, with a significantly lower rate of bleeding.

Background: We report in here a very unusual appearance of a duplicated popliteal vein found in a male cadaver. Popliteal vein is usually a single vein present deep in the popliteal fossa which is formed by the union of venae comitantes of the anterior and posterior tibial arteries.Methods: Anatomical variation in the lower extremity was identified during routine dissection of human cadaver.Result: We noted the presence of unilateral doublepopliteal veins which were formed at the lower end of popliteal fossa. Both the veins were found closely related to the popliteal artery and both of them received tributaries. In the adductor canal both the popliteal veins joined to form the femoral vein.Conclusion: It has been believed that such venous variations in lower limbs have important implications for diagnostic ultrasonography imaging in cases which are suspected with deep vein thrombosis. Thus this case reported in here is very helpful for surgeons for proper diagnosis and management of deep vein thrombosis and also to radiologists to aid in the interpretation of venograms.Bangladesh Journal of Medical Science Vol.16(1) 2017 p.150-153

Introduction: The post-thrombotic syndrome (PTS) is the most complication of deep vein thrombosis who deserves an early management. The aim of this study was to determine the epidemio-clinical profile and the management of PTS. Methods: This was a retrospective and descriptive study for a period of 6 years from January 2013 to December 2018, performed at the Cardiovascular Surgery Unit in JRA Teaching Hospital Antananarivo, including all patients who presented post-thrombotic syndrome after an acute episode of deep venous thrombosis. Results: 106 patients were recorded among 315 patients who presented an episode of DVT (33.65%) and 14110 patients admitted in this period (0.75%). The average age was 46.18 years old. There were 30 males (28.30%) and 76 female (71.69%). The most important risk factors of PTS were previous history of varicose veins (50%), sedentary lifestyle (45.28%), insufficiency of anticoagulant therapy (68.86%) and proximal DVT (47.16%). Delayed of diagnosis were greater than or equal to 2 years after an acute DVT in 86 patients (81.13%). The most clinical signs were edema (56.60%) and varicose veins (54.71%). According the Villalta’s score, PTS were mild in 48 patients (45.28%), moderate in 47 patients (44.33%) and severe in 11 patients (10.37%). Management was lifestyles change (45.28%), compression stockings (100%), anticoagulant therapy (100%) and surgical treatment (65.09%). Conclusion: The frequency of PTS was 33.65% in our study. PTS reduces quality of life of patients, but it can be avoided if the treatments of DVT are adapted. Keywords: Deep vein thrombosis, Post-thrombotic syndrome, Epidemiology, Management

D Dimer

SummaryThe current D-Dimer ELISA methods provide high sensitivity and negative predictive value for the diagnosis of deep vein thrombosis but these methods are not suitable for emergency or for individual determination. We have evaluated the performance of 3 newly available fast D-Dimer assays (Vidas D-Di, BioMerieux; Instant IA D-Di, Stago; Nycocard D-Dimer, Nycomed) in comparison with 3 classic ELISA methods (Stago, Organon, Behring) and a Latex agglutination technique (Stago). One-hundred-and-seventy-one patients suspected of presenting a first episode of deep vein thrombosis were investigated. A deep vein thrombosis was detected in 75 patients (43.8%) by ultrasonic duplex scanning of the lower limbs; in 11 of them the thrombi were distal and very limited in size (<2 cm). We compared the performance of the tests by calculating their sensitivity, specificity, positive and negative predictive value for different cut-off levels and by calculating the area under ROC curves. The concordance of the different methods was evaluated by calculating the kappa coefficient. The performances of the 3 classic ELISA and of the Vidas D-Di were comparable and kappa coefficients indicated a good concordance between the results provided by these assays. Their sensitivity slightly declined for detection of the very small thrombi. Instant IA D-Di had a non-significantly lower sensitivity and negative predictive value than the 4 previous assays; however its performance was excellent for out-patients. As expected, the Latex assay had too low a sensitivity and negative predictive value to be recommended. In our hands, Nycocard D-Dimer also exhibited low sensitivity and negative predictive value, which were significantly improved when the plasma samples were tested by the manufacturer. Thus significant progress has been made, allowing clinical studies to be planned to compare the safety and cost-effectiveness of D-Dimer strategy to those of the conventional methods for the diagnosis of venous thrombosis.

SummaryDoppler ultrasound flow examination, strain gauge plethysmography and contrast venography were performed in 160 lower limbs of 80 in-patients. Deep vein thrombosis (DVT) was suspected in 87 limbs. Using measurement of venous stop-flow pressure, the Doppler method had an overall sensitivity of 83%. By combined use of Doppler and Plethysmography, sensitivity was increased to 96%. Specificity was 62% and 51%, respectively. With a positive and a negative predictive value of 80% and 73%, respectively, the combination of both non-invasive methods cannot reliably replace venography in the diagnosis of DTV, although all (40/40) thromboses proximal to or involving the popliteal segment were detected by either Doppler and Plethysmography or both.After exclusion of 14 patients (18%) suffering from conditions known to alter the results of these non-invasive methods, the positive predictive value of abnormal findings in both Doppler and Plethysmography was increased to 94% for suspected limbs, whilst negative predictive value of both negative Doppler and Plethysmography was 90%, allowing the avoidance of venography in these patients.

SummaryIn order to investigate whether a more intensive initial oral anticoagulation still would be safe and effective, we performed a prospective randomized study in patients with deep vein thrombosis. They received either the conventional regimen of oral anticoagulation (“low-dose”) and heparin or a more intense oral anticoagulation (“high-dose”) with a shorter period of heparin treatment.In the first part of the study 129 patients were randomized. The “low-dose” group reached a stable therapeutic prothrombin complex (PT)-level after 4.3 and the “high-dose” group after 3.3 days. Heparin was discontinued after 6.0 and 5.0 days respectively. There was no difference in significant hemorrhage between the groups, and no clinical signs of progression of the thrombosis.In the second part of the study another 40 patients were randomized, followed with coagulation factor II, VII, IX and X and with repeated venograms. A stable therapeutic PT-level was achieved after 4.4 (“low-dose”) and 3.7 (“high-dose”) days, and heparin was discontinued after 5.4 and 4.4 days respectively. There were no clinical hemorrhages, the activity of the coagulation factors had dropped to the same level in both groups at the time when heparin was discontinued and no thromboembolic complications occurred.Our oral anticoagulation regimen with heparin treatment for an average of 4.4-5 days seems safe and reduces in-patient costs.

BACKGROUND: Symptoms and clinical signs suggestive of deep vein thrombosis (DVT) are common but may have numerous possible causes. OBJECTIVES: 1) To identify the most frequent clinical symptoms and correlate them with duplex ultrasound scan (DS) findings; 2) to identify high-risk clinical conditions for DVT; and 3) to evaluate time since the onset of symptoms and DS examination. METHODS: A total of 528 patients with a clinical suspicion of DVT were evaluated by DS performed by experienced vascular ultrasonographists. RESULTS: DVT was present in 192 (36.4%) of the patients. The external iliac vein was involved in 53 patients (10.04%), the femoral veins in 110 (20.83%), the popliteal vein in 124 (23.48%), and veins below the knee were involved in 157 (29.73%) of the cases. Limb swelling was present in 359 cases (68%), and 303 (57.4%) complained of pain. Sixty nine patients received a DS due to suspected or proven pulmonary embolism (PE); 79 patients were in postoperative period. In the multivariate analysis, independent risk factors for DVT included age>65 years (OR=1.49; 95% confidence interval [95%CI] 1.01-2.18; p=0.042), edema (OR=2.83; 95%CI 1.72-4.65; p<0.001), pain (OR=1.99; 95%CI 1.3-3.05; p=0.002), cancer (OR=2.32; 95%CI 1.45-3.72; p<0.001), and PE (OR=2.62; 95%CI 1.29-5.32; p=0.008).Time since the onset of symptoms did not differ between the groups. CONCLUSIONS: In the present study, 36.4% of the patients referred to DS had DVT. Age > 65 years, presence of limb swelling, pain, cancer, and suspected or proven PE should be considered as major risk factors for DVT.

Background: Venous Thromboembolism (VTE) is a clinical disorder characterized by the pathological occurrence of single or many thrombi developing mainly in the deep veins of the lower limbs and pulmonary veins but also other parts of the venous circulation, albeit less. A frequently occurring venous thrombosis is a deep vein thrombosis (DVT), which is the presence of thrombus in deep veins of the lower extremity. Once this clot fragment is swept off (embolism), it moves along with the venous blood and flows to the pulmonary vessels, where it may result in a clinically significant disorder called pulmonary thromboembolism (PTE). Thrombosis occurring in the superficial veins would only cause discomfort but generally with insignificant consequences. Aim: This study aimed to assess patterns and risk factors of venous thromboembolism (VTE) among patients in the Aseer region. Methodology: A record-based descriptive analysis (retrospective) was used in this study. The clinical study targeted the patients with venous thromboembolism (VTE including PE & DVT) either admitted with the diagnosis or complicated during the hospitalization period in Aseer Central Hospital during the period from January 2010 to June 2019. Data extracted using pre-structured data collection sheet. The extracted data were patients' bio-demographic data, VTE related data, treatment received and relevant complications of treatment, and patient’s follow-up history. Results: The study included total of 207 patients with thromboembolism. The age of patients was between 15 - 100 years old with the average age being 57.3+12.9 years. Approximately 58% of the patients were female. Deep vein thrombosis (DVT) was recorded in 60.4% of the cases and 27.5% of them were diagnosed with pulmonary embolism (PE) while 12.1% had both PE and DVT. Exact of 59.6% of cases with PE had immobilization history for 24 to 72 hours as compared to 31.2% of DVT and 44% of patients with mixed thromboembolism. DM was recorded among 14% of PE cases and 21.6% of DVT. Warfarin with Enoxaparin was the most frequently given treatment in total (23.2%). Heparin followed by Warfarin was the second most common treatment. Conclusions and recommendation: The study revealed that VTE was commonly reported especially DVT and PE among the recorded cases and it was bilateral in a considerable number of cases. Immobilization with chronic disease and morbid obesity was noted as the most significant predictor for VTE.

Введение. Влияние стандартной и альтернативных схем антикоагулянтной терапии на степень и скорость реканализации глубоких вен привлекает внимание современных исследователей. Цель исследования: сравнение эффективности терапии тромбоза глубоких вен (ТГВ) нижних конечностей варфарином и ривароксабаном в отдаленном периоде. Материалы и методы. В исследование включено 94 пациента с ТГВ нижних конечностей, которые были разделены на 2 группы в зависимости от назначенной схемы лечения. Средний возраст 50 пациентов группы 1 составил 44,0 12,6 лет, 44 больных группы 2 39,5 11,7 лет. Пациентам группы 1 был назначен варфарин, группы 2 ривароксабан в течение 6 мес после выписки. Конечная точка наблюдения 4 года. Результаты. Прием антикоагулянта ранее установленного срока прекратили 18 (36) пациентов из группы 1 и 2 (4,5) пациента из группы 2. Режим эластической компрессии в обеих группах пациенты соблюдали нерегулярно. Рецидив венозных тромбоэмболических осложнений в группе 1 отмечен в 11 (22) случаях, в группе 2 у 7 (15,9) пациентов. Отрицательная динамика ультразвукового обследования складывалась у пациентов обеих групп: у 16 пациентов группы 1 и у 9,1 группы 2 появились признаки поражения ранее неизмененных вен или окклюзия ранее проходимой вены после перенесенного тромбоза без клиники острого венозного тромбоза в анамнезе. Трофические расстройства отмечены у одного пациента группы 2 и у 1/3 пациентов группы 1 к четвертому году наблюдения. Значимые отличия между группами были получены по таким параметрам, как приверженность к лечению и степень тяжести венозной недостаточности, оцениваемая клинически, в пользу ривароксабана. Заключение. Неудовлетворительные результаты лечения при использовании стандартной схемы терапии ТГВ требуют назначения препаратов из группы новых оральных антикоагулянтов с возможным внедрением схемы профилактического приема. Introduction. Effect of standard and alternative anticoagulant therapy regimens on the degree and rapidity of deep vein recanalization attracts the attention of modern researchers. Aim: to compare the treatment effectiveness of deep vein thrombosis (DVT) of lower limbs with warfarin and rivaroxaban in the long-term period. Materials and methods. The study included 94 patients with DVT of lower limbs they were divided into 2 groups depending on the prescribed treatment regimen. The average age of 50 patients of group 1 was 44.0 12.6 years, 44 patients of group 2 39.5 11.7 years. Warfarin was prescribed to patients of group 1, rivaroxaban to patients of group 2 treatment was prescribed for 6 months after discharge. The endpoint of observation was 4 years. Results. 18 (36) patients from group 1 and 2 (4.5) patients from group 2 stopped taking the anticoagulant earlier than target date. Elastic compression treatment patients in both groups kept irregularly. Recurrence of venous thromboembolic complications in group 1 was noted in 11 (22) cases, in group 2 in 7 (15.9) patients. The negative ultrasound dynamics was observed in patients of both groups: 16 of patients in group 1 and 9.1 in group 2 had lesion signs of previously unchanged veins or occlusion of a previously passable vein after thrombosis without clinic of acute venous thrombosis. Trophic disorders were identified in 1 patient in group 2 and in 1/3 of patients in group 1 by the 4th year of observation. Significant differences between the groups were obtained in favor of rivaroxaban according to such parameters as adherence to treatment and the severity of venous insufficiency. Conclusion. Unsatisfactory results of DVT treatment with standard therapy regimen require the administration of new oral anticoagulants with the possible introduction of prophylactic regimen.
