Thoracoabdominal aortic aneurysm

Mitsuru Sato, Shunsuke Kawamoto, Yoshikatsu Saiki
Aneurysm in the pancreatic arcade artery is an uncommon event, and is usually associated with the condition of median arcuate ligament syndrome. The stenosis at the base of the celiac axis has been presumed to be attributable to a relative increase in flow and pressure within the pancreatic arcade, resulting in subsequent development of the aneurysm. We, herein, present a rare case with rapid development of a pancreatic arcade artery aneurysm immediately after the replacement of a thoracoabdominal aortic aneurysm...

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...

BACKGROUND: Current guidelines for imaging surveillance after proximal aortic repair are not evidence based. This study sought to characterize the incidence and causes of reintervention after proximal aortic operations to provide data to guide the frequency and duration of postoperative surveillance. METHODS: Data on all patients undergoing proximal aortic operations (ascending, with or without root, with or without aortic valve replacement, or with or without arch) during a 9-year period (n = 869) at a single institution were prospectively collected...

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...

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...

Free esophageal perforation following a hybrid visceral debranching and distal endograft extension to repair a ruptured thoracoabdominal aortic aneurysm (TAAA) is a rare complication. The authors report a 56-year-old male who underwent elective thoracic endovascular aortic repair of a thoracic aneurysm. Four and a half years later, he presented with a new aneurysm extending from the distal end of the thoracic stent graft to the aortic bifurcation involving all the visceral arterial branches. The TAAA ruptured while he was awaiting an elective repair, and as a result, he underwent an emergency hybrid procedure...

Motor evoked potential (MEP) monitoring has been used to prevent neurological complications such as paraplegia in patients who underwent thoracic or thoracoabdominal aortic aneurysm (TAA/TAAA) surgery. The object of this study was making a systematic review to survey the performance of MEP monitoring during TAA/TAAA open repair surgery. We searched electronic databases for relevant studies. We summarized the diagnostic data with summary sensitivity, summary specificity and forest plots of pooled sensitivity, and conducted sub-group analysis...

OBJECTIVE: To report our long-term experience in using the hybrid technique in complex thoracoabdominal aortic aneurysms (TAAAs). METHODS: Between March 2005 and September 2013, 10 patients with TAAA underwent hybrid procedures with open renovisceral revascularization and thoracoabdominal aortic endografting. Patients were analyzed retrospectively. RESULTS: Six men and 4 women with a mean age of 66 years (range 54-81 years) were treated electively during the study period...

OBJECTIVES: The long-term function of branch grafts to the visceral and renal arteries during open thoracoabdominal aortic aneurysm repair is unknown. We assessed the patency of single and multiple branch grafts with postoperative imaging studies in patients followed for up to 13 years. METHODS: A total of 99 of 130 patients undergoing open thoracoabdominal aortic aneurysm repair who received a total of 298 branch grafts to the celiac, superior mesenteric, and renal arteries were evaluated with serial imaging studies at 6- to 12-month intervals...

OBJECTIVE: To assess the usability of a fully automated fusion imaging engine prototype, matching preinterventional computed tomography with intraoperative fluoroscopic angiography during endovascular aortic repair. METHODS: From June 2014 to February 2015, all patients treated electively for abdominal and thoracoabdominal aneurysms were enrolled prospectively. Before each procedure, preoperative planning was performed with a fully automated fusion engine prototype based on computed tomography angiography, creating a mesh model of the aorta...

In the recent years, the application of vascular plugs has been widespread in peripheral and aortic interventions. Between December 2013 and December 2014, four men, with different complex aortic pathologies (two remaining aortic dissections and two thoracoabdominal aneurysms), successfully underwent endovascular treatment with Amplatzer Vascular Plug (St. Jude, St. Paul, Minn., USA). We report the different techniques applied in each case and the benefits of this approach in achieving thrombosis of false lumen, avoiding aneurysmal aorta enlargement and reducing risk of aortic rupture or death...

PURPOSE: To report operative and midterm outcomes of fenestrated endovascular aneurysm repair (FEVAR) with the Anaconda device. METHODS: A retrospective analysis was conducted of 39 consecutive patients (median age 74 years; 36 men) treated with the fenestrated Anaconda stent-graft between July 2011 and December 2015 at a single center. Indications for FEVAR were abdominal aortic aneurysms (AAAs) with neck anatomy unsuitable for a standard stent-graft. Median infrarenal neck length was 4 mm (range 0-9)...

OBJECTIVE: The purpose of this study was to determine the role of smooth muscle cell-derived hypoxia-inducible factor-1α (Hif-1α) in the pathogenesis of aortic aneurysms. APPROACH AND RESULTS: Control mice and smooth muscle cell-specific hypoxia-inducible factor-1α-deficient mice were infused with β-aminopropionitrile for 2 weeks and angiotensin II for 6 weeks to induce aortic aneurysm formation. Mutant mice experienced increased levels of aneurysm formation of the thoracic or abdominal aorta with more severe elastin disruption, compared with control mice...

Thoracoabdominal aortic aneurysms (TAAA) are rare events with an incidence of 5.9 cases per 100,000 persons per year. In Germany approximately 940 TAAA procedures are performed annually. The cause of TAAA is mostly degenerative but they can also occur on the basis of an aortic dissection or connective tissue disease (e. g. Marfan's syndrome). Patients often have severe comorbidities and suffer from hypertension, coronary heart disease or chronic obstructive pulmonary disease, mostly as a result of smoking...

We report a case of a 35-year-old male who underwent thoracoabdominal aortic repair of a chronic dissecting aortic aneurysm, Crawford extent II. Preoperative computed tomography showed thrombosis of almost all intercostal arteries. Precise diagnostic assessment demonstrated the Adamkiewicz artery originating from the left lateral thoracic artery and subscapular artery, which would have been at risk after using a standard Stoney's incision, thus potentially causing paraplegia or paraparesis due to spinal cord ischemia...

BACKGROUND: Mobile intra-aortic thrombus without atherosclerosis, aneurysm, or congenital coagulopathy is very rare, and there are few reports especially in young or middle-aged patients. Furthermore, there are presently no established guidelines or common strategies for the treatment of mobile intra-aortic thrombus. In this case report, we describe the first case of intra-aortic thrombus caused by secondary erythrocytosis and describe the recommended treatment strategy for intra-aortic thrombus...
