As a normal variation of the cerebral venous angioarchitecture, developmental venous anomalies (DVAs) represent a rare cause of intraparenchymal hemorrhage. Different from mixed vascular lesions, such as capillary malformations (CMs), arteriovenous malformations (AVMs), arteriovenous fistulas (AVFs), and thrombosis, here we describe the first case of a ruptured hemodynamic aneurysm associated with a DVA and introduce the first use of hybrid operation for the treatment of a hemorrhagic DVA. A 14-year-old girl suffered from sudden onset of headache, aphasia and left hemiplegia...

OBJECTIVE: Cerebral venous infarction (CVI) is a rare vascular disease, most commonly caused by cerebral venous thrombosis, which leads to brain tissue ischemia and anoxia, followed by necrosis, hemorrhage, and infarct formation. CVI has diverse clinical manifestations; thus, diagnosis is very difficult, and the prognosis is poor. The goal of this study is to provide a theoretical basis for treating patients suffering from CVI combined with high intracranial pressure. To this end, a rabbit model of CVI was established by placing a recoverable epidural sacculus...

INTRODUCTION: Neck dissection is a part of the standard surgical procedure in the management of head and neck malignancy. Diplopia following neck dissection is a rare entity; hence, its diagnosis and management strategies needed to be discussed for prevention of its grave consequences. CASE REPORT: A 30-year-old male patient presented with binocular horizontal diplopia following total thyroidectomy and neck dissection. On evaluation, there was internal jugular vein (IJV) thrombosis followed by cerebral venous sinus thrombosis (CVST)...

BACKGROUND: Cerebral vein thrombosis (CVT) is a rare, life-threatening disease affecting one adult per 100,000 per year. Genetic risk factors are deficiencies of the natural anticoagulant proteins antithrombin, protein C, protein S or single nucleotide polymorphisms such as factor V Leiden and prothrombin 20210A. In 20% of patients, the cause of CVT remains unknown. AIM: To identify novel genetic risk factors for CVT using targeted next-generation DNA sequencing (NGS)...

Robot-assisted laparoscopic radical prostatectomy (RRP) has traditionally been done using transperitoneal (TP) approach. This requires patients to be in the steep Trendelenburg position with antecedent risks of high intraoperative ventilatory pressure, post-operative confusion status, corneal and cerebral edema, deep vein thrombosis (DVT), predisposes risk of intestinal injury and slight delay in bowel recovery. Extraperitoneal (EP-RRP) approach circumvents the above given issues. Between July 2013 and October 2016, 57 patients underwent RRP for adenocarcinoma done by a single surgeon (NR)...

Cerebral venous thrombosis is a rare condition which constitutes 0.5% to 2% of all types of stroke and carries a mortality of up to 20% to 50%. It leads to cerebral edema, infarction, hemorrhage and venous hypertension. Clinically the diagnosis is confirmed using enhanced computed tomography (CT) angiography which demonstrates an empty delta sign in cerebral veins, particularly in the superior sagittal sinus. However, postmortem CT (PMCT) findings on cerebral venous thrombosis have not been documented in the literature...

BACKGROUND AND PURPOSE: The role of recanalization of the occluded dural sinus or vein in the outcome of patients with cerebral venous thrombosis (CVT) is not established. We aimed to systematically review, in patients with CVT, (1) the recanalization rate and its association with (2) clinical outcome and (3) CVT recurrence. METHODS: Systematic search in MEDLINE (Medical Literature Analysis and Retrieval System Online), Cochrane Library, and clinicaltrials.gov (inception to September 2017)...

Eosinophilic granulomatosis with polyangiitis (EGPA; ie, Churg-Strauss syndrome) is one of the antineutrophil cytoplasmic antibody-associated vasculitis syndromes. Although extravascular granulomatoses are a well-known histopathological feature, the diverse histopathologic spectrum of cutaneous lesions has not been described in detail. Thus, this study sought to investigate the possible correlation between the clinical features and histopathology of cutaneous lesions in EGPA cases, focusing on systemic thrombogenic conditions, such as visceral infarction and deep vein thrombosis...

Thrombotic storm (TS) is a rare, acute, hypercoagulable state characterized by multiple thromboembolic events affecting at least two different areas of the vascular system/organs over a short period of time. Typical triggers include inflammation, infections, minor trauma, surgery, pregnancy, and the puerperium. A single thrombotic event can set off a number of thromboembolic events, often including unusual locations like hepatic, portal, or renal veins, skin (purpura fulminans) , adrenal glands, and cerebral sinus venous thrombosis...

PURPOSE: Headaches are a very common symptom and imaging is important to rule out symptomatic causes. For clinical differentiation between primary and secondary headaches an exact anamnesis and neurological examination are important. The aim of this study is therefore to identify anamnestic and neurological information that is associated with secondary headaches. Moreover, this study gives an overview of the causes and differential diagnoses of secondary headaches. METHODS: We performed a retrospective analysis of 239 patients ≥18 years with headaches who had undergone computed tomography or magnetic resonance imaging...

Deep vein thrombosis, renal vein thrombosis, and cerebral venous sinus thrombosis in children are frequently described complications of nephrotic syndrome (NS). Early diagnosis and treatment with anticoagulants is the key for a good outcome. There are a few reported cases of portal vein and superior mesenteric thrombosis in adults in association with NS. Here, we describe two cases of portal vein thrombosis with variable extent of involvement of superior mesenteric vein in association with relapse of NS. A high degree of suspicion, ultrasonography of the abdomen along with Doppler study of abdominal vessels, and computed tomography angiography can only pick up such unusual sites of thrombosis and facilitate early management...

Jing Tao, Elena N Bukanova, Shamsuddin Akhtar
Background: Although factor Xa inhibitors have become a popular choice for chronic oral anticoagulation, effective drug reversal remains difficult due to a lack of specific antidote. Currently, 4-factor prothrombin complex concentrate (4F-PCC) is considered the treatment of choice for factor Xa inhibitor-related major bleeding. However, safety of 4F-PCC and its risk of thrombosis when used for this off-label purpose remain unclear. The purpose of this retrospective study is to determine the rate of thromboembolism when 4F-PCC is used for the emergent reversal of factor Xa inhibitors...

BACKGROUND: Cardiac surgery of the newborn and infant with complex congenital heart disease (CHD) is associated with a high rate of intraoperative bleeding complications. CHD-related anatomic features such as valve stenoses or patent arterial ducts can lead to enhanced shear stress in blood stream and thus cause acquired von Willebrand syndrome (aVWS). OBJECTIVE: To evaluate the intraoperative incidence and impact of aVWS after cardiopulmonary bypass (CPB) in neonates and infants with complex CHD...

Stroke and hepatic vein thrombosis are highly associated with neoplasia but are extremely rare events in young, pregnant women. Rare and recurrent thrombotic events in pregnancy increase the suspicion for occult malignancy. We describe the case of a healthy 31-year-old G2P1 who presented with visual changes and dysarthria during pregnancy. Imaging showed cerebral infarcts. Her thrombophilia evaluation was negative. During delivery, she was diagnosed with fulminant Budd-Chiari Syndrome. Hepatic ultrasound suggested malignancy or metastasis, and postpartum CT scan and biopsy confirmed the diagnosis of Stage IV pancreatic cancer...

Loss-of-function mutations in coagulation cascade proteins lead to bleeding diasthesis. In contrast, gain-of-function mutations in these proteins, which are exceptionally rare, lead to hereditary thrombosis. This is best exemplified by Factor V (i.e., Factor V Leiden) and Factor II (i.e., p.Arg596Leu). Here, we report a family with hereditary thrombosis. The proposita presented with cerebral venous thrombosis accompanied by infarction at the age of 12 years. Despite anticoagulation therapy with oral warfarin, she later developed deep venous thrombosis in her hepatic portal veins at the age of 27 years...
