SummaryAlthough the oral anticoagulants provide effective prophylaxis against postoperative deep vein thrombosis following fracture of neck of femur there is a need for an antithrombotic agent which needs less laboratory control and does not cause haemorrhagic complications. It has been suggested that drugs causing inhibition of platelet function may fulfil these requirements. A controlled trial was carried out in which aspirin, RA 233, or a combination of these drugs was compared with a placebo in the prevention of post-operative deep vein thrombosis. In thirty patients undergoing surgery for fractured neck of femur the incidence of post-operative calf vein thrombosis, as detected by 125I-fibrinogen scanning, was not significantly different between the untreated and treated groups.

Nearly 2 years ago we discussed the use of low-dose subcutaneous heparin1 and concluded that this drug in doses of 5000 units 1 or 2 hours before operation and then 12-hourly, lowers the incidence of deep-vein thrombosis after most major operations, other than those for fractured neck of femur. Haemorrhage is not a serious problem. More is now known about the mode of action of heparin; further studies on the prevention of deep-vein thrombosis have been published; and preliminary data are available on the effect of low-dose heparin on the incidence of post-operative embolism.

SummaryTreatment with streptokinase (‘Kabikinase’) was given to 26 patients with venographically confirmed deep vein thrombosis extending into the popliteal vein or above. Treatment was continued for 4 days and the patients were allocated randomly to oral anticoagulant therapy or a course of treatment with ancrod (‘Arvin’) for 6 days followed by oral anticoagulant therapy. The degree of thrombolysis as judged by further venographic examination at 10 days was not significantly different between the 2 groups. The majority of patients showed clinical improvement but there was no appreciable difference between the groups at 3 and 6 months. Haemorrhagic complications were a more serious problem during the period of treatment with ancrod than during the equivalent period in the control group.

A congenital Antithrombin III (AT III) deficiency affecting 7 members of 3 families is reported.The first throrabo-embolic accidents were observed between the age of 22 and 35 : they were spontaneous or occured after delivery or oral contraception. in one patient, a deep vein thrombosis was observed during heparin treatment. in 2 cases, recurrent pulmonary embolic episodes required vena cava ligation. No thromboembolic accident was observed during oral anticoagulation.AT III was measured by an amidolytic method and by the Mancini method on plasma and serum ; the antithrombin activity was determined on serum by the von Kaulla method. in 7 patients, a decreased AT III was found by all the methods performed. The AT III level was around 50 % in patients treated or not by oral anticoagulants One patient was studied during heparin treatment and then under oral anticoagulants : AT III levels were lower under heparin.

There is an undisputed thesis: CANCER has an often COMPLICATION such as DEEP VEIN THROMBOSIS. Cancer is the second leading cause of death globally, and is responsible for an estimated 9.6 million deaths in 2018. (according to World Health Organization). Sickness rate of deep vein thrombosis is approximately 100 per 100 000 population annually. Sickness rate of cancer in different countries is approximately 130-500 per 100 000 population annually. Thus, if deep vein thrombosis is considered to be a complication of cancer we must identify both these diseases simultaneously with frequency of 20 -76.9% The Research Objective To determine whether peripheral vein thromboses are the complications of cancer. The Method of the Research Randomized prospective parallel controlled trial.

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.
