BACKGROUND: We report the concurrence of a spinal dural arteriovenous fistula (DAVF) and multiple perimedullary arteriovenous fistulas (PAVFs) presenting with subarachnoid hemorrhage (SAH). Moreover, the bleeding site was detected 1 month after onset. CASE DESCRIPTION: A 56-year-old man was admitted to our hospital with an SAH. A DAVF and two PAVFs were detected at the C2 level by two rounds of digital subtraction angiography. The source of bleeding, an aneurysm on the feeding artery of PAVF, was detected at the second angiogram, which was performed 1 month after the onset of SAH...

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is an uncommon form of stroke that, when severe, can be a therapeutic challenge. Endovascular mechanical thrombectomy (EMT) techniques have significantly evolved over the past decade, but data regarding the efficacy and safety of EMT for CVST are poorly defined. OBJECTIVE: To summarize the large number of case series on this relatively rare condition and establish trends in the outcomes of EMT for CVST. METHODS: A literature review was performed using PubMed and Medline to identify reports of three or more patients with CVST treated with EMT...

BACKGROUND: This study aimed to introduce an improved surgical procedure to reduce the incidence of urinary tract complications after renal transplantation in mice using a modified bladder patch-to-bladder anastomosis technique. METHODS: Renal isotransplantation was performed in 28 male C57BL/6 mice. The urinary tract was reconstructed with a ureteral anastomosis between the donor's small bladder patch and the recipient's bladder. The bladder patch was secured through a cystotomy in the recipient's bladder mucosa and seromuscular layers, which were sutured in a double-layer manner...

Morphologic characteristics of angiographic doughnut-shaped aneurysms of the intracranial internal carotid artery (ICA) have been rarely reported in the literature and were discussed only radiologically. In this case, surgical clipping was performed, and the specimen from the aneurysm was examined to correlate the pathologic findings and morphologic characteristics. A 59-year-old male presented with diffuse subarachnoid hemorrhage secondary to a ruptured vascular lesion originating from the intracranial portion of the right ICA...

Most ischemic strokes are managed on the ward or on designated stroke units. A significant proportion of patients with ischemic stroke require more specialized care. Several studies have shown improved outcomes for patients with acute ischemic stroke when neurocritical care services are available. Features of acute ischemic stroke patients requiring intensive care unit-level care include airway or respiratory compromise; large cerebral or cerebellar hemisphere infarction with swelling; infarction with symptomatic hemorrhagic transformation; infarction complicated by seizures; and a large proportion of patients require close management of blood pressure after thrombolytics...

Brain arteriovenous malformations (AVMs) are traditionally considered congenital lesions, arising from aberrant vascular development during the intrauterine period. Rarely, however, AVMs develop in the postnatal period. Individual case reports of de novo AVM formation in both pediatric and adult patients have challenged the traditional dogma of a congenital origin. Instead, for these cases, a dynamic picture is emerging of AVM growth and development, initially triggered by ischemic and/or traumatic events, coupled with genetic predispositions...

Bleeding and thrombotic events remain a significant cause of morbidity in pediatric patients supported with ventricular assist devices (VADs). The objective of this study is to identify the association between markers of anticoagulation and bleeding and thrombosis events during Berlin Heart ExCor support. A retrospective, single-center analysis of 9 patients supported with the Berlin Heart ExCor was performed. Inflammatory and anticoagulation parameters including C-reactive protein, fibrinogen, partial thromboplastin time (PTT), and platelet count were measured at 48 and 24 h before and after bleeding or thrombosis events...

Deep vein thrombosis and pulmonary embolism are associated with considerable morbidity and mortality in hospitalized patients, accounting for up to 10% of hospitalization-related deaths in both surgical and medical patients. Pharmacologic thromboprophylaxis has been demonstrated to be effective, safe, and cost-effective in preventing hospital-acquired venous thromboembolism (VTE) among medical inpatients, and clinician awareness of thrombotic risk promotes prescription of thromboprophylaxis. Guidelines recommend stratification of thrombotic risk for all patients and, unless contraindicated, administration of VTE prophylaxis...

PURPOSE OF REVIEW: This article is a practical guide to identifying uncommon causes of stroke and offers guidance for evaluation and management, even when large controlled trials are lacking in these rarer forms of stroke. RECENT FINDINGS: Fabry disease causes early-onset stroke, particularly of the vertebrobasilar system; enzyme replacement therapy should be considered in affected patients. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), often misdiagnosed as multiple sclerosis, causes migraines, early-onset lacunar strokes, and dementia...

Photodynamic therapy (PDT) is a promising modern approach for cancer therapy with low normal tissue toxicity. This study was focused on a vascular-targeting Chlorine E6 mediated PDT. A new angiographic imaging approach known as M-mode-like optical coherence angiography (MML-OCA) was able to sensitively detect PDT-induced microvascular alterations in the mouse ear tumour model CT26. Histological analysis showed that the main mechanisms of vascular PDT was thrombosis of blood vessels and hemorrhage, which agrees with angiographic imaging by MML-OCA...

During the last decade, the development of large clinical and population-based cohorts led to new findings in the epidemiology and the pharmacoepidemiology of immune thrombocytopenia (ITP). The incidence is estimated to 3-4 for 10(5) inhabitants/year, with a slight female predominance and peaks in children and patients after 60 years. The incidence rate is 9 for 10(5) inhabitants/year in males after 75 years. Variations across ethnic groups are discussed. In France, there is a North-South gradient and a peak of incidence during winter suggesting the role of viruses in ITP pathophysiology...

Thrombolytic therapy using tissue plasminogen activator (tPA) in acute stroke is associated with increased risks of cerebral hemorrhagic transformation and angioedema. While plasma kallikrein (PKal) has been implicated in contributing to both hematoma expansion and thrombosis in stroke, its role in the complications associated with the therapeutic use of tPA in stroke is not yet available. We investigated the effects of tPA on plasma prekallikrein (PPK) activation and the role of PKal on cerebral outcomes in a murine thrombotic stroke model treated with tPA...

BACKGROUND: Acute hyperglycemia on admission is common in acute myocardial infarction (AMI) patients regardless of diabetic status, and is known as one of prognostic factors. However, the effect of hyperglycemia on non-diabetic patients is still on debate. METHODS: A total of 12,625 AMI patients (64.0±12.6years, 26.1% female) who were enrolled in Korea Acute Myocardial Infarction Registry-National Institute of Health between November 2011 and December 2015, were classified into 4367 diabetes (65...

REVIEW
Melvin E Klegerman
Once thrombi have formed as part of the pathology defining myocardial infarction, ischemic stroke, peripheral arterial disease, deep venous thrombosis or other embolic disorders, the only clinically meaningful thrombolytic agents available for reversing the thrombogenic process are various plasminogen activators. These agents are enzymes that reverse fibrin polymerization underlying the coagulation process by converting endogenous plasminogen to plasmin, which cleaves the fibrin network to form increasingly smaller protein fragments, a process known as fibrinolysis...
