Thrombosis of unusual venous sites encompasses a large part of consultative hematology and is encountered routinely by practicing hematologists. Contrary to the more commonly encountered lower extremity venous thrombosis and common cardiovascular disorders, the various thromboses outlined in this review have unique presentations, pathophysiology, workup, and treatments that all hematologists should be aware of. This review attempts to outline the most up to date literature on cerebral, retinal, upper extremity, hepatic, portal, splenic, mesenteric, and renal vein thrombosis, focusing on the incidence, pathophysiology, provoking factors, and current recommended treatments for each type of unusual thrombosis to provide a useful and practical review for the hematologist...

INTRODUCTION: A wide variety of non-genetic and genetic factors have been shown to associate with increased risk for cerebral venous thrombosis (CVT). However, there is a paucity of risk factor data and conclusions about their impact are often conflicting. Herein, we quantified the associations of non-genetic and genetic risk factors for CVT in adults. MATERIALS AND METHODS: Electronic databases were searched up to January 2017. Meta-analyses were performed (RevMan v5...

BACKGROUND: Anticoagulation with unfractionated heparin (UFH) or low molecular weight heparin (LMWH) is the mainstay for the treatment of patients with acute cerebral vein thrombosis (CVT) with or without intracranial hemorrhage (ICH). AIM: We conducted a systematic review and meta-analysis to determine the efficacy and safety of LMWH compared to UFH for the treatment of acute CVT. METHODS: An electronic search of MEDLINE, Pubmed, CENTRAL and Google Scholar was performed...

BACKGROUND: Myeloproliferative neoplasms (MPNs) are frequently identified as an underlying cause in patients with non-cirrhotic portal vein thrombosis (PVT). The aim of this study was to describe the long-term outcome of patients with PVT and MPN. METHODS: A cohort study was performed including all adult patients referred to our hospital between 1980 and 2008 with non-cirrhotic, non-malignant PVT and confirmed MPN. RESULTS: A total of 44 patients (70% female) were included, with a median age at PVT-diagnosis of 48 years (range 18-79)...

Splanchnic vein thrombosis (SVT) encompasses Budd-Chiari syndrome (BCS), extrahepatic portal vein obstruction (EHPVO), and mesenteric vein thrombosis. Philadelphia-negative myeloproliferative neoplasms (MPNS) are the leading systemic cause of non-cirrhotic and non-malignant SVT and are diagnosed in 40% of BCS patients and one-third of EHPVO patients. In SVT patients the molecular marker JAK2 V617F is detectable up to 87% of those with overt MPN and up to 26% of those without. In the latter, other MPN molecular markers, such as mutations in JAK2 exon 12, CALR and MPL genes, are extremely rare...

Myeloproliferative neoplasms (MPNs) are the most common cause of Budd-Chiari syndrome (BCS) and nonmalignant, noncirrhotic portal vein thrombosis (PVT). In this meta-analysis, we determined the prevalence of MPNs and their subtypes as well as JAK2V617F and its diagnostic role in these uncommon disorders. MEDLINE and EMBASE databases were searched. Prevalence of MPNs, JAK2V617F, and MPN subtypes were calculated using a random-effects model. A total of 1062 BCS and 855 PVT patients were included. In BCS, mean prevalence of MPNs and JAK2V617F was 40...

Cerebral sinus-venous thrombosis (CSVT) is a rare life-threatening disease with an estimated annual incidence of 3-4 cases per million in adults and 7 cases per million in neonates. Brain tumors, cerebral infections and traumas are local risk factors for CSVT, but the commonest encountered risk factors are oral contraceptive use, pregnancy and puerperium that make the disease predominant in female sex. In 15-20 % of patients, the disease remains unprovoked, i.e., occurring in the absence of predisposing factors...

BACKGROUND: The purpose of this statement is to provide an overview of cerebral venous sinus thrombosis and to provide recommendations for its diagnosis, management, and treatment. The intended audience is physicians and other healthcare providers who are responsible for the diagnosis and management of patients with cerebral venous sinus thrombosis. METHODS AND RESULTS: Members of the panel were appointed by the American Heart Association Stroke Council's Scientific Statement Oversight Committee and represent different areas of expertise...
