Percutaneous drainage is now the accepted technique for draining abscesses in most body locations, especially since the evolution over the past 10-15 years of precise imaging localization of fluid collections, improved methods of percutaneous drainage, and improved antibiotic regimens. Initially,…
Percutaneous image-guided biopsy has gained wide popularity. It can be used to establish the identity of superficial or deep masses in many parts of the body. Advances in cytopathologic techniques, the ability to precisely guide needles to various locations in…
Venous pathology is eight times more common in the lower extremities than arterial disease. However, the range of clinically important venous pathology in the lower extremities is relatively narrow, with thrombotic disorders, chronic occlusion, and valvular insufficiency comprising more than…
The lower-extremity arteries are a common site for vascular diseases. The legs have a relatively large muscle mass and a prominent role in basic daily activities. Lesions in this vascular bed produce troublesome symptoms at an early stage. Advanced disease…
Portal and hepatic venous interventions are increasing due to the growing population of patients with chronic liver disease and the application of more aggressive surgical approaches to hepatic malignancy. Catheter-based techniques are important for the diagnosis and management of these…
The inferior vena cava (IVC) and its tributaries are frequent sites of vascular pathology. Diseases of organs that drain into the IVC may first become clinically apparent when the cava becomes involved. IVC imaging and intervention are prominent components of…
The kidneys receive almost 15% of the cardiac output, although they account for less than 5% of the total body mass. Obstructive arterial diseases of the kidney have both functional (e.g., decreased creatinine clearance) and hormonal (angiotensin-mediated hypertension) implications. There…
The arterial anatomy of the gastrointestinal tract is the most variable of all vascular beds. In addition, there is great diversity in the types of diseases that involve the gastrointestinal arteries and organs. Many visceral disorders, vascular and otherwise, can…
The abdominal aorta and pelvic arteries supply blood to all of the structures below the diaphragm. The pathologic processes that involve these vessels are varied and have major morbidity. This chapter covers aortic-iliac arterial diseases, including the male and female…
Thoracic aortic diseases can be among the most challenging vascular problems to manage. The organs that are supplied directly by this segment of aorta (heart, brain, and spine) are intolerant of ischemia for more than a few minutes. Flow disturbances…
