■ 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…
■ 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…
■ 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…
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…
■ Alternatively, especially in obese patients with substantial abdominal pannus, a curvilinear incision can be placed 1 cm below and parallel to the inguinal ligament to avoid potential skin maceration and…
■ Planning and performing subintimal recanalization and reentry into the true lumen of the femoral and popliteal arteries are described herein. PATIENT HISTORY AND PHYSICAL FINDINGS ■ Patients with clinical symptoms and…
■ Primary vascular tumors are exceedingly rare, frequently mimic other oncologic disease processes, and may evolve slowly—leading to delay in diagnosis and treatment. Although most commonly arising from large vessels such…
■ In situ replacement: Low-grade infections without sepsis or invasive infection and those with distal occlusive disease may be best treated with in situ graft replacement. ■ Graft replacement material ■ Graft material…
■ Progressive renal artery stenosis (RAS) or occlusion may predispose to renovascular hypertension (RVH; most common form of secondary hypertension) and ischemic nephropathy.2 Aortic atherosclerosis at the ostia or proximal renal…
