BACKGROUND: Changes in the coagulation system during pregnancy and puerperium produce a physiological hypercoagulable state. These changes are thought to be the cause of the higher rates of deep vein thrombosis, pulmonary embolism, stroke, and mechanical prosthetic valve thrombosis during pregnancy. Thrombolysis can be a treatment option in this cases. However, there are no available data from randomized controlled trials in pregnant patients and information about the security of thrombolytics in pregnancy is missing...

Atherothrombosis is a leading cause of cardiovascular mortality and long-term morbidity. Platelets and coagulation proteases, interacting with circulating cells and in different vascular beds, modify several complex pathologies including atherosclerosis. In the second Maastricht Consensus Conference on Thrombosis, this theme was addressed by diverse scientists from bench to bedside. All presentations were discussed with audience members and the results of these discussions were incorporated in the final document that presents a state-of-the-art reflection of expert opinions and consensus recommendations regarding the following five topics: 1...

Acute ischaemic stroke, myocardial infarction and pulmonary embolism are the main causes of mortality and morbidity worldwide. Thrombolysis by intravenous injection of recombinant tissue plasminogen activator (rtPA) remains the most common non-interventional treatment to recanalize occluded vessels. However, this procedure is limited by significant drawbacks, including high doses and bleeding complications. Recent studies showed that fucoidan targets the intraluminal thrombus in vivo. We have developed a chimaera covalently linking fucoidan, able to target platelets within the thrombus, to dilysine, able to non-covalently bind rtPA...

Spontaneous intracerebral hemorrhage (ICH) is the most common cause of intraventricular hemorrhage (IVH) in adults. Complicating approximately 40% of ICH cases, IVH adds to the morbidity and mortality of this often fatal form of stroke. It is also a severity factor that complicates subarachnoid hemorrhage and traumatic brain injury, along with other less common causes of intracranial bleeding. Medical and surgical interventions to date have focused on limiting ICH and IVH expansion, controlling intracranial pressure, and relieving obstructive hydrocephalus...

The combination of alteplase, a recombinant tissue plasminogen activator, and edaravone, an antioxidant, reportedly enhances recanalization after acute ischemic stroke. We examined the influence of edaravone on the thrombolytic efficacy of alteplase by measuring thrombolysis using a newly developed microchip-based flow-chamber assay. Rat models of embolic cerebral ischemia were treated with either alteplase or alteplase-edaravone combination therapy. The combination therapy significantly reduced the infarct volume and improved neurological deficits...

BACKGROUND: Central retinal artery occlusion (CRAO) is an ophthalmological emergency, the retinal analog of a stroke. To date there is no consensus or national guidelines on how this disorder should be managed. As academic neurologists and ophthalmologists treat CRAO frequently, we set out to understand how these clinicians approach patients with CRAO with a national survey. METHODS: We identified university-associated teaching hospitals offering vascular neurology, neuro-ophthalmology and/or retina fellowships in the US and asked the directors of the programs to respond to questions in an open response format to profile the acute management of CRAO at their institution...

OBJECTIVES: Arteriovenous malformation (AVM) rupture could lead to intraventricular hemorrhage (IVH), a particularly severe form of intracranial bleeding. The epidemiology, presentation, management and outcomes of IVH related to AVM rupture have not been clearly addressed yet. The aim of the present study was to investigate the characteristics of IVH related to AVM rupture, with particular attention paid to functional outcomes and to the impact of intraventricular fibrinolysis (IVF). PATIENTS AND METHODS: Between 2011 and 2015, all patients suffering from IVH admitted in two tertiary neurosurgical centers were included in a prospective register...

Stroke is a rare event during pregnancy (10/100,000) and can be ischemic (24%), hemorrhagic (74%) or both (2%). Pregnancy probably increases the risk even if it is discussed for arteriovenous malformation (AVM), aneurismal subarachnoid hemorrhage (SAH) and cavernomas. Between 2010 and 2012, 31 maternal deaths were associated with stroke. In 22 cases, stroke was the direct cause of death giving a maternal mortality ratio of 0,9/100,000 witch is not different from the former report (2007-2009). There were 2 cerebral thrombophlebitis, 2 ischemic strokes and 18 hemorrhagic strokes (4 SAH, 2 AVM)...

Cerebral infarction is a cerebrovascular disease caused by local brain ischemic necrosis or softening, which is associated with diabetes, obesity, hypertension and rheumatic heart arrhythmia. Previous studies have indicated that aspirin is a potential oral anticoagulant in the treatment of cerebral ischemic stroke. However, the potential mechanism mediated by aspirin in cerebral infarction therapy is not well understood. The present study analyzed the therapeutic effects of aspirin on cerebral infarction and investigated the underlying molecular mechanism of aspirin‑ameliorated benefits for thrombolysis...

Anticoagulant therapy is commonly used for the prevention and treatment of patients with deep venous thrombus. Evidence has shown that rivaroxaban is a potential oral anticoagulant drug for the acute treatment of venous thromboembolism. However, the rivaroxaban-mediated molecular mechanism involved in the progression of deep venous thrombosis has not been investigated. In the present study, we investigated the efficacy of rivaroxaban and the underlying signaling pathways in the prevention and treatment of rats with deep venous thrombosis...

Although stroke has recently dropped to become the nation's fifth leading cause of mortality, it remains the top leading cause of morbidity and disability in the US. Recent advances in stroke treatment, including intravenous fibrinolysis and mechanical thromboembolectomy, allow treatment of a greater proportion of stroke patients than ever before. While intra-arterial fibrinolysis with recombinant tissue plasminogen is an effective for treatment of a broad range of acute ischemic strokes, endovascular mechanical thromboembolectomy procedures treat severe strokes due to large artery occlusions, often resistant to intravenous drug...

BACKGROUND: Speed of administration conditions the effectiveness of intravenous fibrinolysis in treating acute ischaemic stroke. To reduce the risk of haemorrhagic complications, the intervention is contraindicated in certain cases, such as where the International Normalised Ratio (INR) is ≥ 1.7. This study aimed to determine the reliability of point-of-care INR readings (POC-INR) taken using the CoaguChek(®) XS portable coagulometer compared to laboratory results (L-INR). METHODS: We conducted a retrospective observational study of consecutive patients admitted to our centre with acute ischaemic stroke and who were treated with intravenous fibrinolysis, over a period of 4 years...

We all know about classical fibrinolysis, how plasminogen activation by either tissue-type plasminogen activator (t-PA) or urokinase-type plasminogen activator (u-PA) promotes fibrin breakdown, and how this process was harnessed for the therapeutic removal of blood clots. While this is still perfectly true and still applicable to thromboembolic conditions today, another dimension to this system came to light over two decades ago that implicated the plasminogen activating system in a context far removed from the dissolution of blood clots...

REVIEW
D Vivien
Tissue-type plasminogen activator (tPA) is a serine protease well known to promote fibrinolysis. This is why: its recombinant form (rtPA) can be used, either alone or combined with thrombectomy, to promote recanalization/reperfusion following ischemic stroke. However, its overall benefits are counteracted by some of its side-effects, including incomplete lysis of clots, an increased risk of hemorrhagic transformation and the possibility of neurotoxicity. Nevertheless, better understanding of the mechanisms by which tPA influences brain function and promotes its alteration may help in the design of new strategies to improve stroke therapy...

OBJECTIVE: Blood vessel wall damage often results in the formation of a fibrin clot that traps inflammatory cells, including monocytes. The effect of clot formation and subsequent lysis on the expression of monocyte-derived genes involved in the development and progression of ischemic stroke and other vascular diseases, however, is unknown. Determine whether clot formation and lysis regulates the expression of human monocyte-derived genes that modulate vascular diseases. APPROACH AND RESULTS: We performed next-generation RNA sequencing on monocytes extracted from whole blood clots and using a purified plasma clot system...
