BACKGROUND AND PURPOSE: Accurate diagnosis of acute aortic dissection (AAD) is sometimes difficult because of accompanying central nervous system (CNS) symptoms. The purpose of this study was to investigate the clinical characteristics of Type A AAD (TAAAD) with CNS symptoms. METHODS: We retrospectively reviewed the medical records of 8403 patients ambulanced to our emergency and critical care center between April 2009 and May 2014. RESULTS: We identified 59 TAAAD patients for the analysis (mean age, 67...

Thoracic endovascular repair is considered the first-line treatment in complicated acute type B dissection. Central venous catheters provide valuable vascular access during endovascular treatments. However, central venous catheters are not without complications. Herein, we report a case of central venous catheter insertion into the false lumen of a complicated acute type B aortic dissection by direct aortic puncture. The tip of the central venous catheter was in the false lumen. The central venous catheter was left in place initially and was removed after graft stent deployment...

Takayasu arteritis is a panarteritis of unknown etiology involving the aorta and its main branches, with higher prevalence in women and peak of incidence in the second and third decades of life. Up to 30% of patients have coronary lesions and aortic valve involvement. Presentation mimicking aortic dissection is quite rare. Here described is the case of a young patient, presenting with an acute coronary syndrome associated with severe aortic regurgitation, who underwent emergent surgery with the suspicion of acute aortic dissection...

OBJECTIVES: We sought to examine the prognostic utility of left ventricular (LV) global longitudinal strain (GLS) in asymptomatic patients with ≥III+ aortic regurgitation (AR), an indexed LV end-systolic dimension of <2.5 cm/m(2), and preserved left ventricular ejection fraction (LVEF). BACKGROUND: Management of asymptomatic patients with severe chronic AR and preserved LVEF is challenging and is typically based on LV dimensions. METHODS: We studied 1,063 such patients (53 ± 16 years; 77% men) seen between 2003 and 2010 (excluding those with symptoms, obstructive coronary artery disease, acute AR/dissection, aortic/mitral stenosis, more than moderate mitral regurgitation, and previous cardiac surgery)...

BACKGROUND: This study sought to determine whether assessment of the renal resistive index (RRI) can predict the short-term reversibility of acute kidney injury (AKI) after repair of acute type A aortic dissection (TAAD). METHODS: This prospective study included 62 patients undergoing repair of acute TAAD. Doppler-based RRIs were obtained preoperatively, immediately after the surgical procedure, and 6, 24, and 48 hours postoperatively. The occurrence of AKI was evaluated daily according to Acute Kidney Injury Network criteria...

BACKGROUND: Blood pressure control is an essential therapy for patients with acute type B aortic dissection (ABAD) and should be maintained throughout the entire treatment. Thus, vast majority current guidelines recommend control the blood pressure to lower than 140/90 mmHg. Theoretically, a much lower target may further decrease the risk of propagation of dissection. However, some argued that too lower blood pressure would compromise the organ perfusion. Thus, there is no unanimous optimal target for blood pressure in patients with ABAD so far...

Natural history of acute Stanford type A aortic dissection (AAAD) implies the need of emergent surgical treatment in the vast majority of cases. Nevertheless, conservative treatment has been described to yield acceptable outcomes, when compared to surgery, in selected high risk cases of thrombosed false lumen. We report a significant quick remodelling of the false lumen occurred in an 85-year-old female 6 days after conservative treatment.

Aortic dissection remains a serious cardiovascular emergency with significant early and late mortality and morbidity. Improving outcomes is directly linked to early clinical diagnosis, swift confirmation by appropriate imaging and management by dedicated teams with high levels of expertise in a complex clinical condition.

Intramural hematoma of the esophagus is a rare injury causing esophageal mucosal dissection. Forceful vomiting and coagulopathy are common underlying causes in the elderly population taking antiplatelets or anticoagulation agents. Acute retrosternal pain followed by hematemesis and dysphagia differentiates the hematoma from other cardiac or thoracic emergencies, including acute myocardial infarction or aortic dissection. Direct inspection by endoscopy is useful, but chest computed tomography best assesses the degree of obliteration of the lumen and excludes other differential diagnoses...

BACKGROUND: The effect of acute aortic dissection itself on coagulopathy or surgery-related coagulopathy has never been specifically studied. The aim of the present study was to perioperatively describe consumption coagulopathy in patients with acute aortic dissection. METHODS: Sixty-six patients with acute type A aortic dissection were enrolled in this study from January 2015 to September 2016. Thirty-six patients with thoracic aortic aneurysms were used as a control group during the same period...

OBJECTIVES: We previously performed the frozen elephant trunk (FET) technique for acute type A aortic dissection to try to improve the long-term prognosis. In this study, we report the mid-term results of the FET technique for treating retrograde type A acute aortic dissection using a new device, the J Graft open stent graft (JOSG). METHODS: Between January 2008 and December 2015, 24 patients (mean age: 59.3 ± 13.9 years) underwent total arch replacement with the FET technique using the JOSG for retrograde type A acute aortic dissection...

Late collapsing of a stent graft is an extremely rare event, with one existing report describing this phenomenon. A 65-year-old man with a history of endovascular aortic repair for an abdominal aortic aneurysm presented with paraplegia and bilateral lower limb ischaemia. Contrast-enhanced computed tomography showed a dissection of the descending thoracic aorta and a collapsed stent graft, resulting in bilateral lower limb ischaemia. Subsequent axillo-bifemoral bypass resolved his lower extremity functions. The patient required haemodialysis due to acute kidney failure...

Type A aortic dissection is an acute condition that requires urgent surgical intervention. However, in a subset of patients, aortic dissections go undiagnosed and become chronic, thereby allowing the dissected wall to undergo a distinct remodeling process from that of the surrounding intact wall. Here, we observe the biomechanical and histological changes in the aortic wall of two patients with chronic Type A aortic dissection. Partial or complete disruption of the elastic structure of the medial layer was observed in the dissected wall of both patients; however, aortic stiffness in the region of dissection covaried with a change in collagen content...

BACKGROUND: The surgical management of acute type A aortic dissection is evolving, and many aortic centers of excellence are reporting superior outcomes. We hypothesize that similar trends exist in a multiinstitutional regional consortium. METHODS: Records for 884 consecutive patients who underwent aortic operations (2003 to 2015) for acute type A aortic dissection were extracted from a regional The Society of Thoracic Surgeons database. Patients were stratified into three equal operative eras...
