BACKGROUND: Cardiac sympathetic denervation (CSD) to treat ventricular arrhythmias (VAs) requires transection at the middle or lower third of stellate (cervicothoracic) ganglia (SG). However, the morphological appearance of the adult SG and distribution of neuronal somata within it are not well described. OBJECTIVE: To determine the morphology of left and right SG (LSG and RSG) and the distribution of somata within. METHODS: LSG and RSG (n=28) from 14 embalmed adult cadavers were dissected intact...

Aneurysm-osteoarthritis syndrome is a recently discovered inherited autosomal dominant connective tissue disease caused by SMAD3 mutations. Aneurysm-osteoarthritis syndrome is responsible for 2% of familial thoracic aortic aneurysms and dissections and is characterised by aneurysms, dissections, and tortuosity throughout the arterial tree in combination with osteoarthritis. Early-onset osteoarthritis is present in almost all patients. We present the case of a non-syndromic young boy with SMAD3 mutation isolated from the dilated aortic root and ascending aorta without osteoarthritis...

Residual Type B aortic dissection following open surgical repair of a Type A thoracic aortic dissection- can sometimes be complicated by collateral blood supplies, which can impact existing flow patterns, and result in progressive aneurysmal dilatation of the thoracic false lumens. We report a unique case that describes the clinical presentation of an infrarenal to innominate artery collateral blood flow that complicated a chronic residual type B dissection, which was timely diagnosed using multi-modality imaging, and successfully managed through an innovative minimally-invasive endovascular treatment strategy (without thoracotomy) with no neurological sequela...

BACKGROUND: This study aimed to propose a new surgical strategy, i.e., the transcervical video-assisted mediastinoscopic lymphadenectomy (VAMLA) with esophagectomy via the left transthoracic approach for patients with esophageal cancer (EC), and to compare the outcomes with those of esophagectomy via the right thoracic approach. METHODS: From December 2014 to March 2016, 49 cases were enrolled in this non-randomized concurrent control study. Twenty-eight patients with EC who underwent transcervical VAMLA with esophagectomy via the left transthoracic approach were assigned into the study group, while 21 EC patients undergoing esophagectomy via the right transthoracic approach during the same period were enrolled into the control group...

OBJECTIVE Proximal junctional kyphosis (PJK) can progress to proximal junctional failure (PJF), a widely recognized early and serious complication of multisegment spinal instrumentation for the treatment of adult spinal deformity (ASD). Sublaminar band placement has been suggested as a possible technique to prevent PJK and PJF but carries the theoretical possibility of a paradoxical increase in these complications as a result of the required muscle dissection and posterior ligamentous disruption. In this study, the authors prospectively assess the safety as well as the early clinical and radiological outcomes of sublaminar band insertion at the upper instrumented vertebra (UIV) plus 1 level (UIV+1)...

A 37-year-old male presented to the Emergency Department with acute worsening of back pain and new onset dyspnea. Transthoracic echocardiography revealed moderate left ventricular dysfunction and a bicuspid aortic valve (BAV). In addition, he was noted to have a dilated thoracic aorta concerning for a dissection, severe aortic insufficiency (AI), and both a pericardial and pleural effusion. Magnetic resonance imaging revealed a Type A ascending aortic dissection. He was taken emergently to the operating room for repair...

OBJECTIVES: The treatment of thoraco-abdominal aortic aneurysm continues to have a high mortality and paraplegia rate. In superaging societies, the methods of performing less invasive operations remain a major issue. We reviewed our 10-year experience in the treatment of thoraco-abdominal aortic aneurysm using a hybrid procedure of combined visceral reconstruction and thoracic endovascular aortic repair. METHODS: Sixty patients underwent a hybrid repair for the treatment of the thoraco-abdominal aortic aneurysm between 2007 and 2016...

INTRODUCTION: Soft tissue and bone radionecrosis are rare but serious complications may occur late after radiotherapy. CASE REPORT: We report the case of an 86-year-old woman with a history an infiltrating ductal carcinoma of the left breast, treated by total mastectomy, left axillary dissection and adjuvant radiotherapy. Eighteen years later, the first radionecrosis lesions appeared and grew progressively in a 6-month period. These lesions are deep, involving the anterior aspect of the 4th to the 6th ribs and infiltrating the chest wall to the left cardio-thoracic space communicating largely with the pericardium...

There are very few surgical options available for treating a patient with winged scapula caused by a long thoracic nerve (LTN) injury. Therefore, we devised a novel technique based on a cadaveric dissection whereby regional intercostal nerves (ICN) were harvested and transposed to the adjacent LTN in 10 embalmed cadavers (20 sides). The LTN was identified along the lateral border of the serratus anterior and ICNs were identified at the mid-axillary line inferior to the lower edge of the pectoralis major muscle...

OBJECTIVE: Aortic dissection (AD) often involves the infrarenal aorta. We review our experience with open infrarenal aortic repair with or without false lumen intentional placement (FLIP) of endografts in the proximal dissected aorta as part of a hybrid strategy to treat complex AD. METHODS: A prospectively maintained database of patients undergoing intervention for AD was reviewed. Data regarding diagnosis, imaging features, nature of the infrarenal repair (one- vs two-stage procedure), endoleaks, need for additional interventions, morbidity, and mortality were collected...

OBJECTIVE: To evaluate short-term outcomes following direct aortic root and arch repair in patients with acute type A aortic dissection (ATAAD) without technical adjuncts. METHODS: Between 2012 and 2016, 94 consecutive patients with ATAAD underwent surgical repair, including aortic root repair (n = 45), root replacement (n = 39), or no root procedure (n = 10). Aortic root repair was achieved by running approximation of the dissected aortic wall circumferentially at the sinotubular junction and reinforcing the coronary ostia with 5-0 Prolene...

BACKGROUND: Frozen elephant trunk (FET) surgery offers a new alternative in the management of complex thoracic aortic aneurysms and dissections. We performed a systematic review and meta-analysis of comparator observational studies evaluating the efficacy of FET compared with conventional aortic arch surgery, primarily focusing on mortality and stroke as well as the secondary outcomes of spinal cord ischemia, major bleeding, and operative time. METHODS: We searched MEDLINE, EMBASE, PubMed, and the Cochrane Library for trials and studies comparing the FET technique with conventional surgery in patients with aortic aneurysms or dissections, or both...

BACKGROUND: In international guidelines, risk estimation for thoracic ascending aortic aneurysm (TAAA) is based on aortic diameter. We previously introduced the aortic size index (ASI), defined as aortic size/body surface area (BSA), as a predictor of aortic dissection, rupture, and death. However, weight might not contribute substantially to aortic size and growth. We seek to evaluate the height-based aortic height index (AHI) versus ASI for risk estimation and revisit our natural history calculations...
