INTRODUCTION: Aortic arch anomalies underlie numerous congenital disorders. Effectively diagnosing and treating them requires close understanding of cardiovascular embryology. As our Center serves the entire pediatric population of our country, we performed a comprehensive retrospective analysis of all aortic arch anomalies diagnosed at our Center over the past 20 years. MATERIALS AND METHODS: We analyzed 40 children with aortic arch anomalies, distinguishing two defect types: Group 1 displayed ring-forming anomalies, and Group 2 other types of aortic arch anomalies that did not form a vascular ring...

BACKGROUND: Double inlet left ventricle (DILV) is a heterogeneous single ventricle anomaly in which initial presentation, and consequently, timing and palliation mode vary based on morphology and degree of pulmonary or systemic outflow obstruction. Very few reports, mostly old, focused on palliation outcomes of DILV. We report current-era results and examine whether morphologic and subsequently surgical factors influence survival. METHODS: Fifty-eight infants with DILV underwent single ventricle palliation...

Bone shaping is often a necessary procedure prior to implant insertion in mandibular full-arch rehabilitations. Adopting guided surgery procedures is necessary to use two distinct templates: one for bone shaping, a second for guided implant insertion. The present report describes the case of a 60-year-old patient requiring a full-arch, immediately loaded implant-supported mandibular rehabilitation. A CAD/CAM-bone supported surgical template for osteoplasty was used to develop a template for guided implant during an all-on-six immediate-loaded computer-aided implant surgery...

Tracheal stenosis in association with the double aortic arch (DAA) is uncommon; however, it carries a high risk of morbidity, mortality, and restenosis. Although surgery is the mainstay of managing a case of the DAA with tracheal stenosis, management of tracheal restenosis requires a multidisciplinary approach. In this case report, we present our successful experience in managing a child of DAA with tracheal stenosis who developed tracheal restenosis after sliding tracheoplasty of trachea.

Congenital abnormalities of the aortic arch include interrupted aortic arch (IAA), coarctation of the aorta (CoA), and double aortic arch (DAA). Aortic arch repair is difficult and postoperative complications are common. However, postoperative tracheobronchial stenosis with respiratory insufficiency is an uncommon complication and is usually caused by increased aortic anastomotic tension. We report here a case of tracheal compression by a mediastinal hematoma following IAA surgery. The patient underwent a repeat operation to remove the hematoma and was successfully weaned off the ventilator...

PURPOSE: To report emergent transcatheter aortic valve implantation (TAVI) to treat acute severe aortic regurgitation caused by valve cusp dysfunction following proximal migration of an endograft implanted in the ascending aorta during endovascular arch repair. CASE REPORT: A 65-year-old man had been previously treated with thoracic and fenestrated endografts in a 2-stage procedure for a chronic type B dissection. At 2-year follow-up, aneurysmal evolution of the distal arch led to development of a proximal type Ia endoleak...

A case of double aortic arch that was well visualized using transthoracic echocardiography is reported. A 38-year-old man underwent transthoracic echocardiography for the evaluation of dyspnea. A suprasternal view of transthoracic echocardiography showed the ascending aorta bifurcate to left and right aortic arches, with blood flow from the ascending aorta to bilateral aortic arches. The diagnosis of right side-dominant double aortic arch was made, and the patient's symptom was conceivably related to compression of the trachea due to a vascular ring...

The transpalatal arch might be one of the most common intraoral auxiliary fixed appliances used in orthodontics in order to provide dental anchorage. The aim of the present case report is to describe a case in which an adult patient with a tendency to class III, palatal compression, and bilateral posterior crossbite was treated with double transpalatal bars in order to control the torque of both the first and the second molars. Double transpalatal arches on both first and second maxillary molars are a successful appliance in order to control the posterior sectors and improve the torsion of the molars...

INTRODUCTION: Congenital variants of the cervical spine may mimic traumatic lesions and may cause recurrent episodes of pain. The spectrum of cervical variants includes persistent apophyses of the transverse processes, persistent epiphyses, vertebral platyspondylia, vertebral hypoplasia, and dysplasia of the vertebral arch. Furthermore, abnormalities of the spinous process have been described including doubled spinous processes and hypertrophies. Unilateral hyperplasia of a spinous process is a rare finding that has only been described rarely as case reports...

Porphyrin tapes possessing meso-meso β-β β-β triple direct linkages have been targets of extensive studies because of their fully conjugated characteristic π-electronic networks. In this paper, we report porphyrin arch-tapes that bear additional carbonyl group(s) or methylene group(s) inserted between one of the β-β linkage(s) of the porphyrin tapes. The carbonyl-inserted porphyrin arch-tapes were efficiently synthesized by double fusion reactions of β-to-β carbonyl-bridged porphyrin oligomers with DDQ and Sc(OTf)3, and were converted to the methylene-bridged porphyrin arch-tapes via Luche reduction with NaBH4 and CeCl3 followed by ionic hydrogenation with HBF4·OEt2 and BH3·NEt3...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysms (TAAs) is in rapid expansion due to its minimal invasiveness. However, TEVAR for an arch aneurysm with a straight stent graft needs surgical reconstruction for supra-aortic vessels. A branched stent graft pioneered by Inoue (branched Inoue Stent Graft [ISG]) has been expected to resolve this problem, but its utility remains to be established in the real clinical setting. This study evaluated the long-term clinical outcome of branched ISGs for TAAs...

A three-month-old female underwent an arterial switch operation for transposition of the great arteries (TGA) with concomitant ventricular septal defect (VSD). After the operation, the patient suffered from stubborn pulmonary infection with increased airway resistance, and could not be weaned from a ventilator. Multispiral computed tomography (CT) scanning suggested a double aortic arch with left arch atresia. The patient underwent a second procedure to resection the left aortic arch. The patient gradually recovered and was successfully weaned from the ventilator...

BACKGROUND: The chimney technique has been developed for the treatment of complex aortic aneurysms. We analyzed the midterm to long-term outcomes of this approach from a single- centre experience. METHODS: From October 2008 to July 2016, 58 patients underwent endovascular aortic aneurysm repair using the chimney technique. Indications for treatment were thoracic aortic aneurysm (TAA) (n = 11), thoracoabdominal aortic aneurysm (TAAA) (n = 2), pararenal aortic aneurysm (PAAA) (n= 15), aortoiliac/isolated hypogastric artery aneurysm (n = 25), type I endoleak after previous TEVAR/EVAR (n=4), proximal pseudoaneurysm after AAA open repair (n = 1)...

INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...

In this article, we report a rare case of double aortic arch. The case presented initially with a foreign object in the oesophagus. The patient was a 2-year-old boy, who was referred with primary symptoms of tussis (15 days) and emesis (2 days). He had a history of ingesting a coin. Routine chest X-ray indicated a rounded, metal foreign object in the upper oesophagus. A half-Yuan coin was removed by gastroduodenoscopy. Echocardiographic imaging suggested that the patient had double aortic arch, which was subsequently diagnosed by CT angiography with three-dimensional reconstruction...
