MR angiography (MRA) is an MRI study of the blood vessels. It utilizes MRI technology to detect, diagnose and aid the treatment of heart disorders, stroke, and blood vessel diseases.
Diagnosis and Non-Surgical Management of Mesenteric Ischemia
Diagnosis and Non-Surgical Management of Mesenteric Ischemia Feature: Diagnosis and Non-Surgical Management of Mesenteric Ischemia - Jaffar Ali Raza, MD, Michael Miller, MD, ?Robert S. Dieter, MD, RVT, ?? Acute mesenteric ischemia (AMI) is further subdivided into occlusive and nonocclusive mesenteric ischemia. 52 Patients with peritoneal signs and documented thrombosis with mesenteric ischemia, infarction, bowel ischemia and bowel infarction require laparotomy for possible thrombectomy and ...

Increased Transmission of Pressure and Serous Componrnts Occur in Porous ePTFE Stent Grafts as Compared to Dacron Stent Grafts
Stent graft treatment reduces intra-aneurysmal pressure to less than 30% of systemic pressure when no endoleak is present; however, significantly greater pressure is present in aneurysms treated with porous ePTFE stent grafts than Dacron grafts. In animals excluded with both Dacron and ePTFE stent grafts, the intra-aneurysmal pressure was non-pulsatile and reduced to less than 30% of systemic pressure with significantly greater pressure present in aneurysms treated with porous ePTFE stent ...

Therapeutic Angiogenesis for the Treatment of PAD ? Where Do We Stand?
Following this description of gene therapy in a patient with PAD, several phase I trials have been conducted, mostly using genes to induce angiogenesis. Regional Angiogenesis with Vascular Endothelial Growth Factor (VEGF) in peripheral arterial disease: Design of the RAVE trial. Regional angiogenesis with vascular endothelial growth factor in peripheral arterial disease: A phase II randomized, double-blind, controlled study of adenoviral delivery of vascular endothelial growth factor 121 in...

Recanalization of Occluded Iliac Artery Allowing Abdominal Aortic Aneurysm Stent Graft
Recanalization of Occluded Iliac Artery Allowing Abdominal Aortic Aneurysm Stent Graft Feature: Recanalization of Occluded Iliac Artery Allowing Abdominal Aortic Aneurysm Stent Graft - Michael Wholey, MD, MBA, ? Initially, the patient was to undergo an endovascular stent graft repair for his abdominal aortic aneurysm and occluded iliac artery; however, the decision was made to recanalize the long segment occlusion and convert him to a standard bifurcated endograft. Vascular Disease ...

Image Guidance of Percutaneous Coronary and Structural Heart Disease Interventions Using a Computed Tomography and Fluoroscopy Integration
Standard angiography (SA) of the coronary vasculature and heart structures is limited by its two-dimensional (2-D) projection of complex three-dimensional (3-D) structures. The use of angiography and fluoroscopy results in imaging artifacts and procedural limitations that makes some interventions difficult. The introduction of 3-D imaging technologies paves the way to a more precise and thorough evaluation of complex structures. Computerized tomographic angiography (CTA) and X-ray based innovative 3-D reconstruction fusion software are major advances in cardiovascular imaging. These imaging techniques provide a 3-D vessel representation and enable the subsequent analysis of 3-D properties with important clinical implications. This review will focus on novel X-ray/CT image fusion techniques that allow for guidance of percutaneous coronary and structural heart disease interventions off- and online.

Diagnostic Angiography of Specific Vascular Territories
The most common variant location for gonadal artery origins is the renal arteries (20%), followed by the adrenal, lumbar, or even iliac arteries. In a small percentage of patients, the lower anterior spinal artery (artery of Adamkiewicz) will arise from the L1 or L2 lumbar artery. If the accessory renal artery is of similar caliber to the main renal artery, thus supplying a large portion of the renal blood supply, revascularization of the stenosed accessory renal arteries can be justified.

Complete Closure of Long Tunnel Patent Foramen Ovale Using the CardioSeal Device
Complete Closure of Long Tunnel Patent Foramen Ovale Using the CardioSeal Device Feature: Complete Closure of Long Tunnel Patent Foramen Ovale Using the CardioSeal Device - Majed Chane, MD, Samuel M. Butman, MD, Richard Heuser, MD Introduction Patent foramen ovale (PFO) is more prevalent in patients with cryptogenic stroke (CS) than in individuals with a stroke of known cause, suggesting that ? (i.e., the migration of a venous thrombus across the PFO to the systemic circulation) may be the ...

Adjunctive Bioengineered Bi-layered Cell Therapy (Apligraf®) With Excimer Laser Revascularization Improves Wound Healing and Limb Salvage in Critical Limb Ischemia
Little data exists on wound care recommendations in the CLI patient with severe arterial insufficiency and few reports exist combining revascularization with the novel class of bioengineered skin substitutes in CLI. 26 Those clinical reports, the reported WH attributes of Apligraf, and our experience in treating CVI and DFU with Apligraf resulted in the adoption of Apligraf as our primary wound treatment in patients with leg and sternal wound complications after CABG,27 and now for ...

Commentary
Commentary Feature: Commentary - Frank J. Criado, MD Emergency Stent-graft Repair for Thoracic Aortic Injury by Castelli et al. is an important paper that lends further credence to the notion that endovascular repair is rapidly becoming the new standard of care in the treatment of traumatic transection of the thoracic aorta. anything and everything that standard surgical repair has accomplished over the past several decades as serious operative morbidity and mortality rates have remained ...
