Catheter-based methods for managing peripheral vascular disease

PREVIEWPrimary care physicians have an important role in identification and referral of patients with signs and symptoms of peripheral vascular disease. Advances in technology have increased the effectiveness of percutaneous catheter-based techniques used to treat stenosis or occlusion in various anatomic sites. However, early evaluation remains an important factor in the success of treatment. In this symposium article, Drs Lips and Vacek review the current catheter-based techniques for managing various types of occlusive disease and include numerous angiographic illustrations from their case files. They also examine the factors affecting choice of treatment approach and briefly discuss the role of thrombolytic therapy.

History of Occlusive Cerebrovascular Disease

Angiography and related procedures are discussed. Ophthalmodynamometry, recording of bruits and temporal pulse, and thermography have been mentioned. Transient ischemic attacks (TIAs) and some causes are described: embolic obstruction, followed by absorption of the clot or its removal in the blood, with symtomatic recovery; hemodynamic crisis resulting from lowering of systemic blood pressure by hemorrhage due to trauma, gastrointestinal bleeding, and other causes with recovery following blood replacement. Special types of occlusive disease include fibromuscular hyperplasia of the carotid, dissecting aneurysm of the aortic arch and branches, causing carotid and vertebral occlusions, moyamoya disease, and low profusion syndrome, generalized or unilateral. Surgical management includes reconstructive surgery and endarterectomy of extracranial vessels supplying the brain and extracranial-intracranial vascular anastomosis.
