Abdominal Aorta Aneursym
-Abdominal aortic aneurysms are seen almost daily in every vascular laboratory. -Aortic aneurysms can be more extensive. -Aneurysms of the aorta can also involve common iliac arteries, common femoral arteries and very often popliteal arteries.
Arterial Bypass Graft Duplex
Lower extremity arterial bypass grafts are used to gain revascularization of the lower limb in patients with severe native vessel disease. Many types of bypass grafts exists. Arterial bypass grafts can be created from the patientís own venous conduits (autolog...
Buerger's disease also known as Thromboangitis obliterans is an inflamatory vascular disorder affecting the distal extremity arteries in young male smokers. The disease is more prevalent in Asia and middle East. Smoking is the only known cause of this disorder...
The main focus of carotid duplex examination is to identify stenotic lesions within the carotid arteries. Significant carotid artery stenosis may lead to transient ischemic deficit(TIA), or stroke. Duplex examination is a reliable tool for assessing the degree...
Chronic Venous Insufficiency
-Defined as retrograde flow in the veins of the lower limbs caused by incompetent or absent valves. -Affects approximatley 20-25% of the adult population with females predominating. -Varied symptoms, ranging from simple venous flares to severe skin changes a...
Arterial dissection (or dissecting aneurysm) results from physical detachment of the inner arterial wall into the lumen. Commonly, dissection involves the intima, or intima with portions of the media. As blood enters the subintimal region, it causes progressiv...
Exercise testing is a highly useful in patients with symptoms of lower extremity ischemia, especially when the resting ABI is normal. Ankle pressure drop after exercise is diagnostic of lower extremity arterial disease. The degree of ankle pressure (or ABI) dr...
Femoro-Popliteal Occlusive Disease
-The assessment of lower limb ischemia is one of the most common examinations performed in a vascular lab -the prevalence of femoro-popliteal occlusive disease is often underestimated. Stenoses usually develop gradually and are accompanied by the formation of...
Fibromuscular dysplasia is an arterial disease of uncertain etiology affecting middle-to-large size arteries of young to middle-aged females. While several subtypes of fibromuscular dysplasia exist, the typical findings in the affected vessels include tandem s...
Haemodialysis Access Grafts
Many types of vascular arrangements have been used for creating haemodialysis access. In principle, haemodialysis grafts are arterio-venous fistulas created from native or synthetic material which contain high-volume high-velocity flows due to the large pressu...
