Thrombosis occurs at sites of injury to the vessel wall, by inflammatory processes leading to activation of platelets, platelet adherence to the vessel wall and the formation of a fibrin network. A thrombus that goes on to occlude a blood vessel is known as a thromboembolism. Venous thromboembolism begins with ...

Endosopic septum pellucidotomy is used for treating patients with unilateral and specific types of bilateral hydrocephalus. The ideal location for septostomy is controversial; however, an avascular region is preferred. As the septal veins (SVs) are viewed only from one side, we studied the symmetry of the SVs in an attempt ...

Pulmonary arterial hypertension (PAH) is a severe, progressive condition of the small pulmonary vessels that leads to increased pulmonary vascular resistance, right ventricular failure and death. Patients in World Health Organization functional class (WHO FC) IV are the most severely affected in terms of disease severity, symptomatic impairment, exercise capacity ...

The lymphatics in the interlobular and subpleural parenchyma contribute to alveolar clearance in the lung, but the information on the remodeling of these lymphatics is quite limited in idiopathic pulmonary fibrosis lungs that contain severe fibrosis in these regions. We compared the alteration of these lymphatics and lymphangiogenesis among idiopathic ...

We have surgically treated 771 patients for thoracic and thoracoabdominal aortic aneurysms since 1983. Our primary effort has been to develop experimentally validated strategies to reduce paraplegia, renal failure, and mortality in these high-risk patients. This approach has led to a spinal cord protection protocol that has reduced paraplegia risk ...

Dense angiogenic sprouting occurs from arteriovenous loops (AVLs) incorporating autologous vein grafts inserted into empty plastic chambers in vivo. The purpose of this study was to determine if angiogenesis from the AVL was limited by substituting an "off the shelf" cold-stored allograft vein instead of an autologous vein. Four Sprague ...

Thoracic venous aneurysms arising from the mediastinal systemic veins are very rare conditions. We report a case of a 42-year-old female who presented with dull aching pain in the left infraclavicular region, dyspnea and palpitation since 4-5 month. Chest roentgenogram revealed superior mediastinal widening secondary to a mass. Contrast enhanced ...

The incidence of posterior vessel wall puncture (PVWP) during central line placement with possible subsequent injury to structures lying behind the vein is unknown. At times the internal jugular vein lies immediately anterior to the carotid artery rather than lateral to it, leading to potential arterial puncture should the needle ...

Pulmonary arteriovenous malformations (PAVM) are congenital vascular communications in the lungs. They act as right to left shunts so that the blood running through these malformations is not oxygenated or filtered. These patients are typically hypoxaemic with exercise intolerance and are at high risk of paradoxical emboli to the brain ...

In this study, the authors describe a simple, nontraumatic procedure for ultrasound-guided placement and maintenance ofjugular and cephalic vein catheterization. The ultrasound scans were performed with a GE Logiq 400 machine connected to a multifrequency (7-11 MHz) linear-array transducer. To find the cephalic vein, longitudinal and transverse color-Doppler ultrasonographic scans ...

Epicardial Connections Between PVs and the LA. Introduction: Some observations support the existence of epicardial connections (ECs) between ipsilateral pulmonary veins (vein to vein ECs [VVECs]), and we have observed venoatrial ECs inserted at distance from the pulmonary vein ostium (vein to atrium ECs [VAECs]). Our aim was to determine the ...

PURPOSE OF REVIEW: Microvascular reconstruction for head and neck cancers has improved both cosmesis and functionality of patients undergoing treatment. Many patients have had prior surgery (neck dissection), radiation and/or chemotherapy as part of their management. When microvascular reconstruction is required after previous treatment, finding appropriate vessels for anastomosis can ...

A popliteal venous aneurysm is rare but needs to be considered a silent threat due to the risk of pulmonary embolism. Using the report of an exemplary case, the diagnostic and therapeutic management including outcome is described. In particular, the favourable, case-adapted surgical approach of aneurysma resection and direct suture ...

An automated method is presented for artery-vein separation in cerebral cortical images recorded with optical imaging of the intrinsic signal. The vessel-type separation method is based on the fact that the spectral distribution of intrinsic physiological oscillations varies from arterial regions to venous regions. In arterial regions, the spectral power ...

Thus far, little has been written concerning echocardiographic identification of the oblique vein of the left atrium, or Marshall's vein. There is much discussion, nonetheless, on the potential significance of the vein, or its ligamentous remnant, as an arrhythmic substrate. We describe here four patients in whom transthoracic echocardiography revealed ...

Lymphangioleiomyomatosis is a rare disorder of unknown origin that almost exclusively affects women of childbearing age. It is characterised by proliferation of abnormal smooth muscle cells (lymphangioleiomyomatosis cells) in the pulmonary interstitium and along the thoracic and abdominal lymphatics. Lymphangioleiomyomatosis may be associated with tuberous sclerosis complex. The most common ...

In this report, we present a technique to extend the function of an antecubital arteriovenous fistula in which both the basilic and the brachial veins were simultaneously transposed to create an autologous graft in the arm. This procedure may particularly be applicable for patients in whom, although a brachio-cephalic fistula, ...

Prolonged cycling has previously been associated with external iliac artery stenosis, termed "cyclists' iliac syndrome." However, no association between external iliac vein stenoses and cycling has been previously described. We describe a unique case of a 70-year-old cyclist presenting with an iliofemoral deep venous thrombosis owing to an external iliac ...
