Dependent edema is the most common cause for leg swelling. In fact, it is very common. Still, many patients and doctors have never heard of it. What does dependent edema look like? Dependent edema is a common cause for swollen legs. It usually causes ankle swelling. The swelling usually come sand goes. It will be…
Chronic mesenteric ischemia can pose a diagnostic and technical challenge for the interventionist. Indications and patient selection for mesenteric artery stenting were covered previously here. This article will outline technical aspects of mesenteric artery stenting. Clinical Vignette A 74-year-old gentleman with a history of antiphospholipid syndrome and celiac artery stenosis treated with a single balloon-expandable…
Just as there are any cold feet causes, there are also many treatments for cold feet. And even though there are some things that all people who have cold feet need to do, there is no real “one size fits all”. When it comes to cold feet treatment, knowing the cause means being able to…
An angiosome is a three-dimensional anatomic sector of the human body that is perfused by a single source artery (1). Each angiosome is connected to surrounding angiosomes through “choke vessels” that may become important when the perfusion capacity from the source artery is diminished. Appropriate perfusion becomes crucial in patients with critical limb ischemia. What…
Lymphedema results in swollen legs or in a swollen arm. Skin changes are also part of lymphedema. Therefore, treatment should go beyond the swelling. Lymphedema skin care should be an integral part of lymphedema treatment. Hopefully, excellent lymphedema skin care can contribute to quality of life and fewer infections. Skin Changes in Lymphedema Lymphedema may…
A 57-year-old diabetic woman with a history of three-vessel coronary bypass grafting presented with unstable angina in the form of chest pain occurring at rest. Stress PET-CT showed a dense reversible anterior wall defect and she was referred for urgent cardiac catheterization. Cardiac catheterization was performed via a left radial artery approach. Angiography revealed a…
Endovenous Laser Ablation, EVLA, is a minimally invasive treatment of chronic venous insufficiency. EVLA works by selective photothermolysis. A laser emitting fiber of varying wavelengths (810-1470 nm) is placed percutaneously within the treated vein. The laser disrupts the vein both directly and indirectly. Certain wavelengths injure the venous wall directly. Other wavelengths heat venous blood…
Multiple sclerosis (MS) is a potentially devastating condition. The cause of MS is uncertain, as is its treatment course. While treatment options for MS are multiplying they are limited by their side-effect profile, their varying efficacy, and their inability to cure. Internal jugular and azygos venoplasty has emerged as a possible new and exciting treatment…
The superficial femoral artery is commonly affected in patients presenting with intermittent claudication and critical limb ischemia. Patients with chronic total occlusion of the superficial femoral artery present a unique challenge for the peripheral interventionalist. Clinical Vignette A 57-year-old diabetic man with a history of left femoral-popliteal bypass grafting presents with progressive right leg claudication….
Systemic thrombolysis is an appropriate therapy in carefully selected patients with submassive and massive pulmonary embolism. However, the systemic administration of thrombolytics is associated with significant risks of bleeding including intracranial hemorrhage. Recent innovations in percutaneous technology have led to the development of a number of catheter-based therapies to treat pulmonary embolism, with the primary…
