■ Arterial thoracic outlet syndrome (aTOS) is the least common presentation of thoracic outlet syndrome and most often involves subclavian artery compression leading to extrinsic compression, poststenotic dilatation, aneurysmal degeneration, and…
■ Computed tomography (CT) arteriography of the abdomen and pelvis, with arterial and venous pelvis, may provide additional useful information regarding the extent of aortic disease and other associated abdominal pathology…
DIFFERENTIAL DIAGNOSIS ■ Neurogenic claudication is frequently confused for arterial claudication. Neurogenic claudication is variable—some good days, some bad—whereas arterial claudication is very consistent. Neurogenic claudication can be relieved by the…
■ Details of prior upper and lower gastrointestinal (GI) bleed, findings of upper GI endoscopy to exclude other causes of nonvariceal upper GI bleeding, history of prior endoscopic management of bleeding…
■ The risk of AAA rupture increases with progressive diameter enlargement.2 Rupture and subsequent aneurysm-related mortality may be prevented by elective surgical repair, either by open interposition grafting or endovascular aneurysm…
■ The causes of NTOS include anatomic variations (anomalous scalene musculature, aberrant fibrofascial bands, and/or cervical ribs) and previous neck or upper extremity injury, which promotes scalene/pectoralis muscle spasm, fibrosis, and…
■ Once the degree and physiologic impact of the disease are determined by noninvasive testing, high-resolution anatomic imaging via either computed tomographic angiography (CTA) or magnetic resonance angiography (MRA) should be…
■ The Trellis system is composed of an infusion catheter of either 15- or 30-cm infusion length, with compliant occlusion balloons at either end of the infusion ports (FIG 2). Following…
PATIENT HISTORY AND PHYSICAL FINDINGS ■ A thorough history should be obtained prior to intervention and should include a detailed description of, if present, symptoms (quality, duration, etc.) that may be…
■ Two hybrid approaches are described in this chapter. ■ Complete visceral debranching and endovascular tube graft repair ■ Partial visceral debranching and physician-modified fenestrated endovascular repair DIFFERENTIAL DIAGNOSIS ■ Paravisceral aortic aneurysms may…
