The value of percutaneous chemical lumbar sympathectomy (LSE) for the treatment of peripheral arterial disease (PAD) is still being discussed controversially. In particular, a benefit for Fontaine stage II PAD could not yet be shown. This case report is about a patient suffering from Fontaine stage II PAD.

Rationale And Objectives: The authors investigate the cerebral effects of selective carotid angiography with carbon dioxide (CO2).

Methods: In 6 pigs, CO2 was injected into the carotid artery with consecutively increasing doses. Cerebral function was monitored with two-channel electroencephalography and somatosensory evoked potentials (SEPs).

Purpose: To evaluate the short-term effectiveness and biocompatibility of Dacron-covered stent-grafts for percutaneous treatment of carotid aneurysms.

Materials And Methods: In eight swine, nine aneurysms were created surgically in the common carotid artery. Percutaneous treatment was performed with Dacron-covered stent-grafts.

Purpose: To determine whether spiral CT angiography allows accurate, quantitative evaluation of anatomic abnormalities, including detection of additional lesions, delineation of plaque morphology, and estimation of degree of internal carotid artery stenosis.

Methods: Spiral CT angiography with a maximum intensity projection technique was compared with selective digital subtraction angiography (DSA) in 92 carotid arteries. The category of stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial: mild (0% to 29%), moderate (30% to 69%), severe (70% to 99%), and occlusion (100%).

Purpose: To decide, whether spiral CT-angiography (CTA) in surface display (SSD)-technique is suitable for accurate quantification of carotid artery stenoses.

Material And Methods: Forty-four patients (25 male, 19 females) with a total of 80 symptomatic carotid artery were studied prospectively with selective cerebral angiography and spiral CTA in SSD-technique. The degree of stenosis was determined according to the NASCET-study.
