We herein report two cases of perigraft effusion mimicking graft infection after debranching thoracic endovascular repair for an anastomotic pseudoaneurysm of the distal ascending aorta. Both patients presented with a bulging tumor on the sternum. Enhanced computed tomography showed no endoleak, but extension of periprosthetic graft fluid to a subcutaneous sternal wound was present. We suspected a deep sternal wound infection; however, cultures of débrided tissues were negative. After drainage of the subcutaneous fluid or negative pressure wound therapy, both patients were doing well without recurrence of effusion...

Ruptured abdominal aortic aneurysm (rAAA) is an emergent condition that carries higher mortality rate. Although there had been development of interventional and surgical technique besides improved critical care, mortality rates were still varied between 35 and 53% in the reported series. Preoperative shock was reported as a major factor predicting mortality rate. Feasibility of simultaneous endovascular repair of rAAA and silent thoracic aortic aneurysm (TAA) is not known. Herein, we aimed to demonstrate the advantage of simultaneous endovascular repair of rAAA and silent TAA in the settling of hemodynamic and neurologic instability...

Left atrial dissection is a very uncommon complication of cardiac surgery and usually causes significant hemodynamic compromise. Little is known about spontaneous dissection of the left atrium. Two patients, one middle-aged man and another elderly woman were evaluated following stroke. Routine trans-thoracic echocardiogram showed vertical division of the left atrium with both chambers communicating with each other through an orifice. Detailed trans-oesophageal echocardiographic study revealed dissection of the left atrium producing an additional false chamber (pseudo-aneurysm) placed posterior to the left atrial appendage and above the postero-lateral aspect of mitral annulus...

Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, and rarely, it is associated with sinus of Valsalva aneurysms (SOVAs). And very infrequently, these SOVAs rupture into left side of heart. We hereby report a case of 12-year-old male with BAV with severe aortic stenosis with a large SOVA that ruptured into the left side of the heart. The anatomy was delineated with multimodality imaging; initially with two-dimensional trans-thoracic echocardiography (TTE), and later on with three-dimensional TTE and with multi detector computed tomography...

BACKGROUND: Surveillance is mandatory for all patients with a thoracic aortic aneurysm (TAA). The frequency of surveillance imaging, however, is not evidence-based, as few data exist regarding TAA growth rates. This study aimed to determine the rate of TAA expansion and to inform surveillance intervals based on TAA diameter. METHODS: Patients with a TAA for whom morphological data were available from serial CT scans were studied. Annualized growth rates based on diameter at presentation and time taken to reach a theoretical intervention threshold of 55 mm were calculated...

Massive hemoptysis from an aortobronchial fistula due to thoracic aortic dissection is an extremely rare symptom, but is a potentially life-threatening condition. We report a case of acute massive hemoptysis due to aortobronchial fistula that was successfully controlled by a simple and rapid thick wedge resection of the lung with hematoma by using the black cartilage stapler. A 65-year-old man was admitted to our hospital with acute massive hemoptysis. After tracheal intubation, chest computed tomography revealed hematoma in the left lung and ruptured aortic dissection from the distal arch to the descending aorta...

Transforming growth factor (TGF)-β signaling disorder has emerged as a common molecular signature for aortic aneurysm development. The timing of postnatal maturation plays a key role in dictating the biological outcome of TGF-β signaling disorders in the aortic wall. In this study, we investigated the impact of deficiency of TGFβ receptors on the structural homeostasis of mature aortas. We used an inducible Cre-loxP system driven by a Myh11 promoter to delete Tgfbr1, Tgfbr2, or both in smooth muscle cells (SMCs) of adult mice...

Aberrant right subclavian artery embolization is problematic in debranching thoracic endovascular aortic repair, because concomitant bypass grafting to the right upper arm may hinder complete embolization. We report a case of a thoracic aortic aneurysm with aberrant right subclavian artery successfully treated with debranching thoracic endovascular aortic repair and bypass grafting. Although endoleakage was found from aberrant right subclavian artery after single use of Amplatzer vascular plug, additional deployment of Amplatzer vascular plug II completely eliminated residual endoleakage...

A hybrid strategy, firstly performed in the 1990s, is a combination of tools available only in the catheterization laboratory with those available only in the operating room in order to minimize surgical morbidity and face with any cardiovascular lesion. The continuous evolution of stent technology along with the adoption of minimally invasive surgical approaches, make hybrid approaches an attractive alternative to standard surgical or transcatheter techniques for any given set of cardiovascular lesions. Examples include hybrid coronary revascularization, when an open surgical anastomosis of the left internal mammary artery to the left anterior descending coronary artery is performed along with stent implantation in non-left anterior descending coronary vessels, open heart valve surgery combined with percutaneous coronary interventions to coronary lesions, hybrid aortic arch debranching combined with endovascular grafting for thoracic aortic aneurysms, hybrid endocardial and epicardial atrial fibrillation procedures, and carotid artery stenting along with coronary artery bypass grafting...

Marfan syndrome is an autosomal dominant connective tissue disorder, predominantly affecting the ocular, skeletal and cardiovascular systems. Here, we present the results of the first genetic testing in 40 Ukrainian Marfan (-like) patients and 10 relatives. We applied a targeted next generation sequencing panel comprising FBN1 and 13 thoracic aortic aneurysm genes. We identified 27 causal mutations in FBN1, obtaining a mutation yield of 67·5%. A significant difference in age at aortic surgery between mutation positive and negative patients was observed...

Spinal cord ischemia remains the Achilles' heel of thoracic and thoracoabdominal diseases management. Great improvements in morbidity and mortality have been obtained with the endovascular approach TEVAR (Thoracic Endovascular Aortic Repair) but this devastating complication continues to severely affect the quality of life, even if the primary success of the procedure - dissection/aneurysm exclusion - has been achieved.Several strategies to deal with this complication have been published in the literature over the time...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) has demonstrated encouraging results and is gaining increasing acceptance as a treatment option for aortic aneurysms and dissections. Yet, its role in managing proximal aortic pathologies is unknown-this is important because in proximal (Stanford type A) aortic dissections, 10% to 30% are not accepted for surgery and 30% to 50% are technically amenable for TEVAR. We describe our case series of type A aortic dissections treated by using TEVAR...

We report a case in which a stent graft and an Amplatzer® vascular plug (AVP) were effective for the treatment of chronic aneurysmal aortic dissection. The patient was a 52-year-old man. At 45 years of age, he developed acute aortic dissection, for which he underwent surgery four times with prosthetic graft replacement in the abdominal aorta, descending thoracic, ascending aorta (without neck branch reconstruction), and thoracoabdominal aorta with the reconstruction of the celiac, superior mesenteric and bilateral renal arteries...

INTRODUCTION: Ruptured descending thoracic aneurysm (rDAA) is a rare but devastating condition. Open aortic surgery which uses cardiopulmonary bypass is associated with a high mortality. Thoracic Endovascular Aortic Repair (TEVAR) is a less invasive approach for which it remains unclear whether outcomes are superior or equivalent to open aortic surgery. In this study, we report our early and midterm outcomes with TEVAR for rDAA. METHODS: This is an observational, retrospective, single center study which included patients with rDAA and treated by TEVAR...

BACKGROUND: In acute DeBakey I aortic dissection presenting with malperfusion syndromes, we assessed whether standard open repair with concomitant antegrade stent grafting (thoracic endovascular aneurysm repair; TEVAR) of the descending thoracic aorta (DTA) improves outcomes compared with standard repair alone. METHODS: From 2005 to 2012, 277 patients with acute DeBakey I dissection underwent emergent operation. Of these, 104 patients (37%) presenting with end-organ malperfusion were divided into those undergoing standard distal repair entailing transverse hemiarch replacement (Standard group, n = 65) versus standard repair with concomitant DTA TEVAR during circulatory arrest (TEVAR group, n = 39)...

BACKGROUND: Paraplegia is one of the most severe complications occurring after the repair of thoracic and thoracoabdominal aortic aneurysms. Remote ischemic preconditioning (RIPC) has been shown to mitigate neurologic damage, and this study assessed its efficacy in preventing spinal cord ischemia. METHODS: The study randomized 16 female pigs into an RIPC group (n = 8) and a control group (n = 8). The RIPC group underwent four cycles of 5-minute ischemia-reperfusion episodes by intermittent occlusion of the left iliac artery...

OBJECTIVES: This study sought to evaluate the diagnostic yield of a dedicated computed tomography angiography (CTA) protocol of the chest, abdomen, and pelvis in patients with fibromuscular dysplasia (FMD). BACKGROUND: FMD is an uncommon vascular disease that may result in stenosis, dissection, or aneurysm of nearly all arterial distributions, typically affecting medium-sized arteries. Findings from the United States Registry for Fibromuscular Dysplasia have suggested the potential need to perform screening imaging of the aorta and medium branch vessels...

Thoracic aortic aneurysms are associated with significant morbidity and mortality. There are multiple underlying etiologies, including genetic abnormalities, that have important implications in their natural history. The variable histologic, anatomic, and clinical presentations necessitate careful consideration of available treatment options. Surgical repair of these aneurysms has been the mainstay of treatment; however, these approaches can carry a relatively high risk of morbidity and mortality. Endovascular approaches have now become first-line therapy for descending thoracic aneurysms, and with advancements in graft technology, endovascular approaches are being increasingly employed for hybrid repairs of the aortic arch and even the ascending aorta...
