Abstract It takes about 3 months to complete “active treatment” of venous thromboembolism (VTE), with further treatment serving to prevent new episodes of thrombosis (“pure secondary prevention”). Consequently, VTE should generally be treated for either 3 months or indefinitely (exceptions will be described in the text). The decision to stop anticoagulants at 3 months or to treat indefinitely is dominated by the long-term risk of recurrence, and secondarily influenced by the risk of bleeding and by patient preference. VTE provoked by a reversible risk factor, or a first unprovoked isolated distal (calf) deep vein thrombosis (DVT), has a low risk of recurrence and is usually treated for 3 months. VTE associated with active cancer, or a second unprovoked VTE, has a high risk of recurrence and is usually treated indefinitely. The decision to stop anticoagulants at 3 months or to treat indefinitely is more finely balanced after a first unprovoked proximal DVT or pulmonary embolism (PE). Indefinite anticoagulation is often chosen if there is a low risk of bleeding, whereas anticoagulation is usually stopped at 3 months if there is a high risk of bleeding. The decision to continue anticoagulation indefinitely after a first unprovoked proximal DVT or PE is strengthened if the patient is male, the index event was PE rather than DVT, and/or d-dimer testing is positive 1 month after stopping anticoagulant therapy.

Abstract Background Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), has significant morbidity and mortality. Acute PE, in particular, is fatal if we miss it, and symptomatic patients of PE sometimes have concomitant DVT. Purpose This study compared the risk of mortality in symptomatic patients of PE with and those without DVT in the long term. Methods The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic VTE objectively confirmed by imaging examination or by autopsy among 29 centers in Japan between January 2010 and August 2014. Patients with both PE and DVT (N=1334) were regarded as PE patients, and the current study population consisted of 1715 PE patients and 1312 DVT patients. Results There were 1203 symptomatic patients of PE, including 381 without and 822 with DVT. In our cohort, the mean age was 67.9±14.9 years, 63% was female, 44% had hypertension, 12% diabetes mellitus, 5% history of VTE. There were 20% of active cancer. Baseline characteristics were well matched except for dyslipidemia (18% vs. 23%, p=0.021) and atrial fibrillation (8% vs. 5%, p=0.045). Patients without DVT had a more severe clinical presentation compared to those with DVT, including hypoxemia, shock and arrest. Moreover, Initial parenteral anticoagulation therapy in the acute phase was administered less frequently in patients without DVT (89% vs. 96%, P=0.0001). Two groups received thrombolysis (20% vs. 26%, P=0.18) and mechanical supports (Ventilator 14% vs. 5%, p<0.001, PCPS 5% vs. 3%, p<0.001, respectively). During follow-up, 93 (8%) patients experienced recurrent VTE events and 98 (8%) major bleeding events, and 323 (27%) patients died. The most frequent cause of death was cancer (11%). There were a significant differences in the cumulative incidences of all-cause death between the groups (32% vs. 24%, P=0.006), whereas there was significant difference in VTE-related death (13% vs. 4%, p<0.001). Estimated freedom rates from death for patients of PE without and those with DVT were as follows: 88% vs 99% at 10-day, 86% vs 95% at 1-month, 75% vs 83% at 1-year, and 64% vs 71% at 5-year, respectively. Landmark analysis Conclusions In symptomatic patients of PE, there was a difference in mortality between groups, but no difference in recurrent VTE. Patients without DVT had a more severe clinical presentation compared to those with DVT, and many VTE-related deaths in the acute phase. The one-month mortality rate differed statistically between groups, but there was no significant difference in long-term survival beyond one month. Most of deaths were due to underlying diseases, mainly cancer, and less commonly due to VTE in the long term.

Procedural Outcome

The post-thrombotic syndrome (PTS) as a long-term consequence of deep vein thrombosis (DVT) is caused by a venous obstruction and/or chronic insufficiency of the deep venous system. New endovascular therapies enable early recanalization of the deep veins aiming reduced incidence and severity of PTS. Extended CDT is associated with an increased risk of bleeding and stenting of residual venous obstruction is indispensable to avoid early rethrombosis. Therefore, this article focuses on measurements during or after thrombolysis indicating post procedural outcome.

Abstract Recurrent venous thromboembolism (VTE, or deep vein thrombosis and pulmonary embolism) is associated with mortality and long-term morbidity. The circumstances in which an index VTE event occurred are crucial when personalized VTE recurrence risk is assessed. Patients who experience a VTE event in the setting of a transient major risk factor (such as surgery associated with general anesthesia for &gt;30 minutes) are predicted to have a low VTE recurrence risk following discontinuation of anticoagulation, and limited-duration anticoagulation is generally recommended. In contrast, those patients whose VTE event occurred in the absence of risk factors or who have persistent risk factors have a higher VTE recurrence risk. Here, we review the literature surrounding VTE recurrence risk in a range of clinical conditions. We describe gender-specific risks, including VTE recurrence risk following hormone- and pregnancy-associated VTE events. Finally, we discuss how the competing impacts of VTE recurrence and bleeding have shaped international guideline recommendations.

В статье представлен клинический случай успешного лечения острой массивной тромбоэмболии лёгочной артерии у пациента после удаления менингиомы. Известно, что частота тромбозов глубоких вен нижних конечностей (ТГВ) в нейрохирургической практике достаточно высока, и может достигать 25-34%. ТГВ является основной причиной более грозной тромбоэмболии легочной артерии (ТЭЛА), частота которой составляет от 1,5% до 3%. На сегодняшний день медицина располагает несколькими эффективными инструментами лечения пациентов с ТЭЛА: от антикоагулянтной терапии до хирургических методов реперфузии. Благодаря слаженной работе в современных многопрофильных клиниках интервенционных кардиохирургов, реаниматологов и нейрохирургов, обеспечивающих своевременную и высокоспециализированную помощь, становится возможным спасение жизней пациентов даже с такой тяжелой и жизнеугрожающей патологией как острая массивная тромбоэмболия легочных артерий. The article presents a clinical case of successful treatment of acute massive pulmonary embolism in a patient after resection of a meningioma. The incidence of Deep vein thrombosis (DVT) in neurosurgical practice is astonishingly high as it might reach 25-34% in some reports, and represents the first cause for pulmonary embolism (PE), which incidence is thought to be between 1,5% and 3%. Nowadays there are several options for treating patients with pulmonary embolism: from anticoagulant therapy to surgical methods of reperfusion. Effective multidisciplinary teams and coordinated team in our clinics can save the lives of people with pulmonary embolism.

The article suggested that after a single episode of deep-vein thrombosis anticoagulant treatment should if possible be continued for at least 6 months. After reconsidering the evidence we think a shorter period, for 3 to 4 months, is more appropriate.

Abstract Twenty-three patients with malignant glial neoplasms were treated with anticoagulant therapy for thromboembolic complications. Fifteen patients had deep vein thrombosis alone, and 8 patients had both deep vein thrombosis and pulmonary embolism. Serum prothrombin times were maintained at 1.25 times control for an average of 5.8 months per patient, for a total patient exposure to warfarin therapy of 132 patient-months (11 patient-years). Only 1 patient suffered a recurrent pulmonary embolism, and this occurred during an episode of gastrointestinal bleeding, when anticoagulant therapy had to be discontinued prematurely. All patients were followed with serial computed tomographic or magnetic resonance imaging scans, and no patient showed radiographic evidence of intratumoral hemorrhage either during or after warfarin therapy. One patient, who died from a large recurrent glioblastoma, was found at autopsy to have scattered foci of intratumoral hemorrhage. This series, together with a review of the available literature, suggests that oral anticoagulant therapy is both a safe and effective means of treating thromboembolic complications in patients with residual malignant glial tumors.
