Chronic thromboembolic pulmonary hypertension (CTEPH) is uncommon. Its diagnosis should not be delayed as its prognosis is poor if not treated. In most cases, an acute pulmonary embolism is found in the medical history of the patient. Once suspected, a specific work-up should be performed in a pulmonary hypertension (PH) center. The ventilation/perfusion scan has a central role in this workup but the emergence of non invasive imaging technologies provides morphological and functional information which take part in the therapeutic decision making, such as operability...

Pulmonary arteriovenous malformations (PAVMs) are atypical vascular structures involving a direct connection between the pulmonary arterial and venous circulations. While PAVMs are a relatively uncommon disorder, unmanaged cases are at risk for the development of serious complications including embolization and infection. Since their first description in 1897, PAVMs have been identified and treated in a variety of ways. Advancements in diagnostic methods and operative techniques have allowed for more effective treatment of the disease...

OBJECTIVES: We describe an alternative surgical technique for the treatment of chylothorax in patients who have had failure of or are not candidates for transthoracic ligation or embolization by interventional radiology. METHODS: We describe our experience with laparoscopic ligation of the cisterna chyli in 3 such patients and compare our results with published literature. We used a 5-port approach as for foregut surgery. We retracted the liver, transected the gastrohepatic ligament, and retracted the stomach to the left...

INTRODUCTION: Vertebral hemangiomas (VH) represent the most common primary bone tumor of the spine and are rarely symptomatic. Currently, there is no consensus for treatment and many therapeutic options are available, alone or in combination including cementoplasty, sclerotherapy, surgery, embolization and/or radiotherapy. OBJECTIVE: To evaluate the clinical and radiological outcome of a multimodal management for symptomatic VH. METHODS: A consecutive prospective and retrospective multicenter study was conducted to review cases of symptomatic VHs between 2005 and 2015...

BACKGROUND: Hypoxia preconditioning has been proven to be an effective method to enhance the therapeutic action of mesenchymal stem cells (MSCs). However, the beneficial effects of hypoxic MSCs in ischemia/reperfusion (I/R) lung injury have yet to be investigated. In this study, we hypothesized that the administration of hypoxic MSCs would have a positive therapeutic impact on I/R lung injury at molecular, cellular, and functional levels. METHODS: I/R lung injury was induced in isolated and perfused rat lungs...

Interventional embolization is a popular minimally invasive vascular therapeutic technique and has been widely applied for hepatocellular carcinoma (HCC) therapy. However, harmful effects caused by transcatheter arterial chemoembolization (TACE) and radioembolization, such as the toxicity of chemotherapy or excessive radiation damage, are serious disadvantages and significantly reduce the therapeutic efficacy. Here, a synergistic therapeutic strategy combined transcatheter arterial embolization and magnetic ablation (TAEMA) by using PLGA-magnetic microspheres (MMs) has been successfully applied to orthotopic VX2 liver tumors of rabbits...

Cryptogenic stroke, or stroke of undetermined cause, presents a remarkably challenging dilemma for the treating physician as there are limited therapeutic options to prevent recurrence. Roughly one third of transient ischemic attacks (TIAs) and ischemic strokes are classified as cryptogenic, with an even greater proportion in young patients. While classification systems have been successfully used in trials to refine therapeutic approaches specific to subtype, there has been little progress made in secondary prevention of cryptogenic stroke...

REVIEW
Wei Li, Hong Yue
We recently found that thymidine phosphorylase (TYMP), also known as platelet-derived endothelial cell growth factor, plays an important role in platelet activation in vitro and thrombosis in vivo by participating in multiple signaling pathways. Platelets are a major source of TYMP. Since platelet-mediated clot formation is a key event in several fatal diseases, such as myocardial infarction, stroke and pulmonary embolism, understanding TYMP in depth may lead to uncovering novel mechanisms in the development of cardiovascular diseases...

Percutaneous and endovascular techniques take an important role in the therapeutic management of patients with hepatocarcinoma. Different techniques of percutaneous ablation, especially indicated in tumors up to 2cm diameter offer, at least, similar results to surgical resection. Taking advantage of double hepatic vascularization and exclusive tumor nutrition by the artery, several endovascular techniques of treating the tumor have been developed. Intra-arterial administration of embolizing particles, alone or charged with drug (chemoembolization), will produce ischemia and consequent necrosis with excellent results in selected patients...

We reported previously that Stachybotrys microspora triprenyl phenol-7 (SMTP-7) showed potential thrombolytic, anti-inflammatory and anti-oxidant effects that account for its excellent pharmacological activity such as having a wider therapeutic time window than tissue plasminogen activator (t-PA) and a significant protection against hemorrhage. The aim of the present study was to evaluate and compare the effect of a new series of SMTPs in the acetic acid-induced embolic cerebral infarct mouse model. Thrombotic occlusion was produced in mice by inducing the transfer of acetic acid-induced thrombi from the right common carotid artery into the brain...

BACKGROUND: Chronic kidney disease (CKD) is an independent risk factor for atrial fibrillation (AF), which is more prevalent among CKD patients than the general population. AF causes stroke or systemic embolism, leading to increased mortality. The conventional antithrombotic prophylaxis agent warfarin is often prescribed for the prevention of stroke, but risk of bleeding necessitates regular therapeutic monitoring. Recently developed direct oral anticoagulants (DOAC) are expected to be useful as alternatives to warfarin...

Cerebral arteriovenous malformations (AVMs) are rare vascular lesions potentially responsible for substantial neurological morbidity and mortality. Over the past four decades, radiosurgery has become a valid therapeutic option for many patients with small intracranial AVMs, but reports describing the use of robotic stereotactic radiosurgery (SRS) are rare. The purposes of this study are to describe the efficacy and toxicity of robotic SRS for AVMs and to review the literature. The reports of 48 consecutive patients treated with SRS were reviewed...

This study describes the use of fluorescence imaging and mass spectrometry imaging, for imaging the anti-angiogenic drug sunitinib, used to treat liver cancer. These techniques allowed for the assessment of local delivery of the unlabeled therapeutic drug. More specifically, the spatial distribution of the drug and its metabolites after local administration was investigated, and drug levels in tumor and liver tissue over time were quantified. For this purpose, sunitinib-eluting microspheres were locoregionally injected into the tumor feeding arteries of rabbits bearing liver tumors...

Paradoxical embolism should be suspected in front of a clinical phenomenon of thromboembolism associated with an anatomical right-to-left shunt. Others potential cardiac sources of thromboembolism must be ruled out. Strokes constitute the most frequent clinical manifestations of paradoxical embolism. Right-to-left left shunts are in connection with intracardiac defects (atrial septal defect and patent foramen ovale) or pulmonary arteriovenous malformations. The probability that a discovered PFO is stroke-related can be evaluated by a score...

The incidence of ramp test echocardiogram-associated embolic events in the setting of therapeutic anticoagulation is likely rare and has not been reported. We present such a case in a patient with a HeartMate II left ventricular assist device (LVAD) whose serial head computed tomography images, deteriorating clinical course, and the multiembolic nature of the event suggest causality. If the pretest probability of pump thrombosis in an individual LVAD patient is sufficiently high, the potential risks of performing a ramp study echocardiogram may not be warranted, even in the setting of adequate anticoagulation...

BACKGROUND: Thrombosis of a mechanical prosthetic heart valve is a potentially life-threatening complication associated with a high mortality. Although thrombolytic therapy has been considered highly beneficial in this situation, very few studies have been conducted to monitor the effectiveness of such thrombolytic therapy among Asian populations. Hence, the study aim was to evaluate the clinical profile, efficacy and safety of the thrombolytic agent streptokinase (SK) in patients with obstructive thrombosis of a left-sided mechanical heart valve...

Renal angiomyolipoma (RAML), though a rare benign tumor, may impose a significant morbidity or even mortality due to its unique characteristics and the complications subsequent to its treatment. The classic tumor variant is composed of smooth muscular, vascular, and fatty components. The most straightforward diagnosis is when the fat component is abundant and gives a characteristic appearance on different imaging studies. In fat-poor lesions, however, the diagnosis is difficult and presumed a renal cell carcinoma...

A 49-year-old male patient presented due to recurrent pain and swelling in the left leg. The patient had had deep venous thrombosis with pulmonary embolism 5 years previously. Since then, he had been treated with Vit-k-antagonists. Pronounced paraumbilical collateral circulation of unknown origin was striking. Doppler sonographic evaluation pointed to May-Thurner syndrome. This was confirmed by phlebography. Venous stenting of the stenosis in the left iliac vein achieved long-term symptom improvement. This case report is intended to draw attention to the rare May-Thurner syndrome as an important differential diagnosis of deep vein thrombosis and, at the same time, identify diagnostic and therapeutic treatment strategies...
