Abstract
Venous disease encompasses a wide spectrum of clinical pathology. Thrombophilias are acquired and inherited hypercoagulable conditions that are prevalent among patients with various manifestations of venous disease. However, treatment guidelines often do not investigate the effect of thrombophilia on treatment outcomes. We aim to review the evidence for the relationship between thrombophilias and venous disease, and highlight situations in which the presence of thrombophilia may affect treatment options and outcomes.

The Evaluation of Aortic Dissections with Intravascular Ultrasonography

Abstract
Intravascular ultrasound is an important intravascular imaging technology that may be used in the operating room or endovascular suite as an adjunct to other imaging modalities in the treatment of vascular disease. It is of critical importance in the endovascular treatment of aortic dissection where it facilitates true lumen access, identification of the primary fenestration, accurate measurement of the normal proximal aorta for suitable endograft choice and real-time assessment of the changes in flow in the true and false lumens.

Introduction
In 1972, Bom and colleagues described the application of miniaturized ultrasound transducers to the tips of flexible intravascular catheters.1,2 These intravascular ultrasound (IVUS) catheters were initially used to obtain high-resolution ultrasound imaging of cardiac and vascular structures. This technology was slow to find clinical relevance.
The Evaluation of Peripheral Arterial Disease with Intravascular Ultrasound

Abstract
Intravascular ultrasound (IVUS) has emerged as a dynamic imaging modality that provides real-time visualization for catheter-based interventions. The image presentation of IVUS permits detailed assessment of plaque and vessel morphology and their response to intervention. IVUS also provides accurate quantitative information regarding lumen area, plaque area, and vessel diameters. In addition, in vivo assessment of atherosclerotic plaques and restenosis has changed the understanding of peripheral arterial disease.
Endovascular Intervention for Lower-Extremity Deep Venous Thrombosis

Deep venous thrombosis (DVT) is the third most common cardiovascular disease in the United States with 600,000 cases reported annually, resulting in more than 100,000 deaths.1,2 Clinical sequelae of DVT are significant in both the acute and chronic settings. Initial consequences include acute lower-extremity symptoms, risk of pulmonary emboli (PE) and death. Long-term consequences include recurrent DVT, lower-extremity venous hypertension, claudication, pain, swelling and ulceration, which can result in significant post-thrombotic morbidity.3–7

Although contrast venography is the standard imaging method for vena cava filter insertion, 
intravascular ultrasound (IVUS) is a safe and effective alternative that allows for bedside placement options, and is especially advantageous for critically ill patients.1–9 Depending on the clinical situation and the filter type used, either a single- or dual-puncture technique can be used.
May-Thurner Syndrome

May-Thurner syndrome — also called iliocaval compression syndrome, Cockett syndrome or iliac vein compression syndrome — occurs secondary to compression of the left iliac vein by 
the overriding right iliac artery. Virchow was the first author to be credited with describing iliac vein compression. It was not until 1957 that May and Thurner brought much attention to the anatomic variant thought responsible for Virchow’s observation.
Life After ASTRAL: Who Should Be Revascularized for Renal Artery Stenosis?

Introduction
Hemodynamically significant renal artery stenosis (RAS) induces hypoperfusion of the affected kidney leading to a constellation of physiologic responses.1 Upregulation of the renin-angiotensin-aldosterone system (RAAS) results in arterial vasoconstriction, impaired natriuresis, and fluid retention.2 Over time, hypoperfusion can lead to renal atrophy and fibrosis.3 Renal artery revascularization can restore perfusion to ischemic kidneys and prevent further injury.4

ABSTRACT:Significant renal artery stenosis (RAS) may result in deterioration of arterial hypertension and/or renal insufficiency and may contribute to cardiovascular diseases such as diastolic and systolic heart failure. Percutaneous transluminal angioplasty (PTA) is the established therapy for RAS of fibromuscular disease origin. The role of cutting balloon angioplasty in this indication still needs to be investigated. In atherosclerotic RAS, stenting has shown superior acute and long-term technical outcomes compared to PTA.
ASTRAL and Beyond: Who is Appropriate to Consider for Renal Artery Revascularization?

ABSTRACT: ASTRAL and the four randomized, controlled trials preceding have shown that unselected revascularization in atherosclerotic renovascular disease (ARVD) is not an appropriate intervention. Despite this, there are clinical situations where renal artery revascularization is of great benefit to the patient. In this review we discuss the different presentations of ARVD and the effects of revascularization for each.
