Background  Despite much progress in the surgical and endovascular treatment of thoracoabdominal aortic diseases (TAADs), there is no consensus regarding the optimal approach to minimize operative mortality and end-organ dysfunction. We report our experience in the past 16 years treating TAAD by open surgery. Methods  A retrospective review of all TAAD patients who underwent an open repair since January 2000 was performed. The primary endpoints included early morbidity and mortality, and the secondary endpoints were overall death and rate of aortic reintervention...

REVIEW

The abdominal aorta is the most common site of an aortic aneurysm. The visceral and most proximal infrarenal segment (aneurysm neck) are usually spared and considered more resistant to aneurysmal degeneration. However, if an abdominal aortic aneurysm (AAA) is left untreated, the natural history of the aortic neck is progressive dilatation and shortening. This may have significant implications for patients undergoing endovascular repair of AAAs (EVAR) as endograft stability and integrity of the repair are dependent on an intact proximal seal zone...

Aortic arch surgery is a technical challenge, and cerebral protection during distal anastomosis is a continued topic of controversy and discussion. The physiologic effects of hypothermic arrest and adjunctive cerebral perfusion have yet to be fully defined, and the optimal strategies are still undetermined. This review highlights the historical context, physiological rationale, and clinical efficacy of various neuroprotective strategies during arch operations.

Aortic root aneurysm is the most common cardiovascular manifestation requiring surgical intervention in patients with Marfan syndrome (MFS), a heritable thoracic aortic disease. Elective replacement of the aortic root is the treatment of choice for patients with aneurysmal complications of the aortic root and ascending aorta. There are two basic approaches to aortic root replacement: valve-sparing (VS) and valve-replacing (VR) techniques. After successful aortic root replacement surgery, several patients with MFS may develop a late complication related to their aortic disease process, such as developing a pseudoaneurysm of the coronary artery reattachment buttons, aneurysmal expansion, or aortic dissection in the remaining native aorta...

The technologies and innovations applicable to endovascular treatment for complex aortic pathologies have progressed rapidly over the last two decades. Although the initial outcomes of an endovascular aortic repair have been excellent, as long-term data became available, complications including endoleaks, endograft migration, and endograft infection have become apparent and are of concern. Previously, the indication for endovascular therapy was restricted to descending thoracic aortic aneurysms and abdominal aortic aneurysms...

Abdominal aortic aneurysm (AAA) is defined as a permanent dilatation of the abdominal aorta that exceeds 3 cm. Most AAAs arise in the portion of abdominal aorta distal to the renal arteries and are defined as infrarenal. Most AAAs are totally asymptomatic until catastrophic rupture. The strongest predictor of AAA rupture is the diameter. Surgery is indicated to prevent rupture when the risk of rupture exceeds the risk of surgery. In this review, we aim to analyze this disease comprehensively, starting from an epidemiological perspective, exploring etiology and pathophysiology, and concluding with surgical controversies...

The use of hybrid techniques to avoid neonatal cardiopulmonary bypass in high-risk individuals is well reported in the setting of hypoplastic left heart syndrome. We describe the use of that technique as a bridging procedure in high-risk neonates with an interrupted aortic arch. We report three cases where hybrid branch pulmonary artery banding and ductal stent implantation has been successfully used to defer complete repair, allowing recovery, maturity, and weight gain. This strategy may be considered for patients deemed at high risk for primary neonatal repair...

Background  To report a case of a high-risk patient treated with hypogastric chimney and aortic endograft for a native infrarenal aorta aneurysmal degeneration, 20 years after an aortobifemoral bypass procedure for severe iliac occlusive disease. Methods  A two-stage procedure was planned. The first stage was right internal iliac artery (IIA) embolization and simple angioplasty of left IIA. The second stage consisted of aortouniiliac endograft with femoral crossover and left IIA chimney. Results  Femoral crossover complicated with early thrombosis, but a decision on conservative medical treatment with anticoagulation was made based on no rest pain or severe claudication...

Atrial myxoma is the most common benign tumor of the heart; moreover, atrial myxoma embolization to the peripheral vessels is rare. We present an unusual case of total acute infrarenal aortic occlusion resulting from embolic implantation from a left ventricular myxoma. A 37-year-old man with acute lower limbs ischemia, spinal cord ischemia, and acute renal insufficiency was urgently operated and discharged after surgery.

Device therapy is a viable alternative to open heart surgery in the management of intracardiac defects. The Amplatzer septal occluder (ASO) is one such device that has been adapted to close a wide variety of cardiac defects with few complications and a high success rate. This is a retrospective review of all the patients who received the ASO between 2012 and 2016 at the University of Kentucky. In total, 169 patients underwent percutaneous closure of a septal defect with Amplatzer during the timeframe studied, and of those, 91% received the device for an atrial septal defect or patent foramen ovale...

Background  There is no consensus regarding the role of red blood cell (RBC) aggregation in the pathogenesis of leg ulcers (LUs) in sickle cell disease (SCD). Objectives  We sought to evaluate whether the cross-sectional determination of RBC aggregation and hematological indices were associated with the presence of LU in homozygous SCD. Methods  Twenty-seven patients with LU and 23 with no history of ulceration were recruited into the study. A laser-assisted rotational red cell analyzer (LoRRca) was used in the determination of the aggregation index (AI), aggregation half-time ( t 1/2 ), and the RBC aggregate strength (AMP)...

Lower extremity arterial injuries (LEAIs) can be complicated injuries resulting in limb loss and death. Patients with LEAI often have multiple injuries increasing the risk for morbidity and mortality. We sought to evaluate the incidence and management of LEAI and to define associations between injuries and outcomes. We performed a retrospective review of LEAI at an urban level-1 trauma center from April 2005 to April 2015. Chi-square tests were used to compare independent groups with respect to mortality and amputation...

Objective  In an era of managed care and cost savings, we are faced with the question of whether another test is necessary to confirm our clinical suspicion. We hypothesized that a few computed tomography angiographies (CTAs) are necessary to identify lower extremity vascular injuries (LEVIs). We reviewed our trauma center's experience in the management of LEVI. Methods  A retrospective review of all trauma patients between 2012 and 2016 was performed. Four-thousand nine-hundred fourteen trauma patients were evaluated with 46 suspected LEVIs (either with cross-sectional imaging and/or operative exploration)...

REVIEW

Adverse effects of advanced glycation end-products (AGEs) on the tissues are through nonreceptor- and receptor-mediated mechanisms. In the receptor-mediated mechanism, interaction of AGEs with its cell-bound receptor of AGE (RAGE) increases generation of oxygen radicals, activates nuclear factor-kappa B, and increases expression and release of pro-inflammatory cytokines resulting in the cellular damage. The deleterious effects of AGE and AGE-RAGE interaction are coined as "AGE-RAGE stress." The body is equipped with defense mechanisms to counteract the adverse effects of AGE and RAGE through endogenous enzymatic (glyoxalase 1, glyoxalase 2) and AGE receptor-mediated (AGER1, AGER2) degradation of AGE, and through elevation of soluble receptor of AGE (sRAGE)...

Intramural hematoma (IMH) is a variant form of aortic dissection characterized by involvement of the aortic media without the presence of an overt intimal flap. Surgical extirpation is the standard of care for type-A IMH in the Western world. However, a conservative approach with anti-impulse therapy has been advocated especially in Japan as a viable alternative. Here, we report a case of an elderly male patient with a history of metastatic stage 4 renal cell carcinoma who was treated with anti-impulse therapy for an acute type-A IMH...

Two cases of thoracic origin of the right renal artery, arising from the level of D11 vertebrae detected on an incidental computed tomography examination are reported. A brief review of embryology is presented. Simultaneous variation of the origin of the right inferior phrenic artery is highlighted as a unique feature of our cases. The importance of this relatively uncommon anomaly in the clinical context is discussed.

In patients with abdominal aortic aneurysms (AAA) and complete iliac occlusion, endovascular aortic aneurysm repair (EVAR) using a bifurcated stent graft has clear advantages over aortouniiliac stent grafts. Bifurcated stent grafts had improved hemodynamic flow and increased primary and secondary patency rates compared with aortouniiliac stent grafts. The use of aortouniiliac stent grafts with femorofemoral crossover bypass is associated with complications including infection of the prosthesis, steal phenomenon, and the associated difficulties for further endovascular access at the site of the femoral anastomosis...
