Hybrid Arch Frozen Elephant Trunk Repair of Complex Arch Aneurysm with Severe Arterial Tortuosity.

Patients with complex aortic arch aneurysms and severe arterial tortuosity represent a unique challenge because of extreme angulations, mixed aneurysm and stenotic disease, and fragile tissues. Novel hybrid arch frozen elephant trunk techniques can expand surgical repair options to include single-stage, complete aortic reconstruction via sternotomy alone, without the need for simultaneous thoracotomy or clamshell incisions. We describe successful hybrid aortic arch reconstruction with Thoraflex Hybrid graft...

Multicenter analysis of endovascular aortic arch in situ stent graft fenestrations for aortic arch pathologies.

In situ fenestration of aortic stent grafts for treatment of aortic arch aneurysms is a new option for endovascular aortic arch repair. So far, only few reports have shown perioperative and short term results of in situ fenestrations for aortic arch diseases. We present the multicenter experience with the (aortic archin situfenestration) technique documented in the AARCHIF registry for treatment of aortic arch aneurysms or localized type A aortic dissections and analyzed perioperative outcome and midterm fo...

A case report: stent implantation to treat coarctation of persistent 5th aortic arch associated with interrupted 4th aortic arch.

Persistent 5th aortic arch is a rare cardiac anomaly that is usually surgically corrected during infancy or early childhood if it is associated with coarctation of the aorta. Here, we report an adult with coarctation of the 5th aortic arch who was successfully treated by stent implantation.

Early outcomes and computational fluid dynamic analyses of chimney reconstruction in the Norwood procedure†.

The ideal configuration of a reconstructed aortic arch in the Norwood procedure for hypoplastic left heart syndrome is still a matter of debate. Chimney reconstruction was developed to avoid postoperative complications and turbulent flow in the aortic arch. This study sought to clarify early outcomes of the procedure and verify its haemodynamic advantages using computational fluid dynamics (CFD).

Native Aortic Arch Interruption in Adulthood: Surgical Management.

Aortic coarctations in adults are mainly represented by recurrent critical narrowing at the site of previous surgical correction, or less frequently by native forms of complex obstructive malformations of the distal arch and isthmus. We present our experience with an unusual form of native adult aortic coarctation presenting as a complete interruption of the aortic arch.

Thoracoscopic Oesophagectomy Using Prone Positioning for Oesophageal Cancer With Right Aortic Arch: A Case Report.

Right aortic arch (RAA) is a rare abnormality of the aortic arch that forms a vascular ring. Oesophageal cancer (EC) accompanied with RAA is even rarer, and in such cases, it is very important to understand the anatomical structure in the upper mediastinum in order to perform a safe and curative operation.

Total endovascular aortic arch repair using chimney and periscope grafts for treatment of ruptured aortic arch pseudoaneurysm.

Aortic arch pseudoaneurysms are rare but quite fatal when ruptured. Owing to its less morbidity and mortality compared with the surgical approach, endovascular and hybrid treatment methods are increasingly preferred. In this report, we present a 58-year-old male patient who has a ruptured saccular aortic arch pseudoaneurysm treated by endovascular approach using parallel grafts.

Endovascular Reconstruction from Aortic Valve to Aortic Arch Using One-Piece Valved-Fenestrated Stent Graft with a Branch: A Proof-of-Concept Study.

To explore the feasibility of endovascular reconstruction of aortic root including aortic valve, sinus of valsalva and ascending aorta by a single stent-graft, a novel valved stent-graft with two fenestrae for preserving the coronary arteries was designed and performed in-vitro on a pig heart based circulation simulating system.

Altered 4-D magnetic resonance imaging flow characteristics in complex congenital aortic arch repair.

Interrupted aortic arch (IAA) is a rare but severe congenital abnormality often associated with bicuspid aortic valve (BAV). Complex re-interventions are often needed despite surgical advances, but the impact of aortic hemodynamics in repaired patients is unknown.

Anomaly In The Embryogenesis Of The Aorta Associated With Subclavian Steal Phenomenon.

Congenital Aortic Arch Anomalies are rare and may be associated with other congenital cardiovascular malformations. The authors report a rare case of anomaly in the aortic arch embryogenesis, presenting with a right aortic arch and an isolated innominate artery, associated with the subclavian steal phenomenon. This condition is discussed considering the Edwards hypothetical double embryonic arch and its clinical aspects.

New type a aortic dissection after a chronic type b dissection , compressing the pulmonary artery. A case-report.

The authors report a case of a 69-year-old man with a 5 years history of medically treated type B aortic dissection, who presented a new retrograde type A dissection (RTAD) of the aortic arch and the ascending aorta. Clinical presentation was suggestive for pulmonary embolism. Computed tomographic angiography revealed a contained rupture of the dissected aortic arch , confined to the connective tissue plane between the arch and the pulmonary arteries. Extrinsic compression of both pulmonary arteries caused ...

Predictors of Acute Kidney Injury Following Aortic Arch Surgery.

Acute kidney injury (AKI) following open aortic arch surgery is a frequent complication associated with increased morbidity and mortality. The primary purpose of this study was to evaluate risk factors for postoperative AKI in patients who underwent open aortic arch surgery utilizing hypothermic circulatory arrest (HCA).

Thrombectomy and reconstruction of the left vertebral artery after total arch replacement: never give up on postoperative stroke.

The patient was a 64-year-old man who had aortic regurgitation, ischemic heart disease, a transverse aortic aneurysm, and an abdominal-common iliac aneurysm. Concomitant operations including aortic valve replacement, coronary artery bypass grafting, and total aortic arch replacement with elephant trunk technique were performed successfully. The patient developed postoperative cardiac tamponade on the 5th postoperative day, resulting in bulbar palsy due to occlusion of the dominant left vertebral artery. Thr...

Contemporary Management of Aortic Arch Aneurysm.

The management of the aortic arch aneurysm is becoming increasingly complex and multidisciplinary. It has evolved since the first successful repair by DeBakey and colleagues in 1957. After these initial repairs, the improvement in open surgical techniques, cardiopulmonary bypass, anesthesia, and perioperative care were the primary drivers of the decrease in morbidity and mortality associated with repair. The development of endovascular technology has spurred another revolution in the management of aortic ar...

A shorter aortic arch sealing ring (< 10mm) distal to the most distal chimney seems to be an additional important factor contributing to a gutter endoleak in aortic arch TEVAR.

The aim of the present study was to define the possible anatomical and technical parameter that might predict the occurrence of gutter endoleak or type Ia endoleak (EL Ia) in patients treated with the chimney graft technique for the brachiocephalic trunk and left common carotid artery due to aortic arch pathologies.

The Buffalo Trunk Technique for Aortic Arch Reconstruction.

The frozen elephant trunk technique facilitates repair of aortic arch and proximal descending aortic pathologies. Commercially available hybrid grafts may simplify this approach by allowing for a single suture line, potentially streamlining the distal anastomosis and improving operative times. However, these devices are currently not readily available in United States. We developed a surgical technique, the Buffalo Trunk, to simplify the frozen elephant trunk procedure that obviates the need for a hybrid gr...

Reduced maternal vitamin A status increases the incidence of normal aortic arch variants.

While common in the general population, the developmental origins of "normal" anatomic variants of the aortic arch remain unknown. Aortic arch development begins with the establishment of the second heart field (SHF) that contributes to the pharyngeal arch arteries (PAAs). The PAAs remodel during subsequent development to form the mature aortic arch and arch vessels. Retinoic acid signaling involving the biologically active metabolite of vitamin A, plays a key role in multiple steps of this process. Recent ...

Calculation of the aortic arch angles from three-dimensional reconstructions of computed tomography scans: Comparison between an automated program and visual assessment.

The curvature of the aortic arch is associated with the risk of endoleak formation after thoracic endovascular aortic repair (TEVAR). However, the adequate assessment of the angles of the aorta continues to represent a major difficulty. We developed a new program based on three-dimensional (3D) reconstructions of computed tomography (CT) scans to objectively identify the location of the aortic points of maximum curvature, and to automatically calculate the main aortic arch angles, comparing final values wit...

Successful Surgical Therapy of a Double Aortic Arch in a 10-Month-Old Mixed Breed Dog.

A 10-month-old female spayed mixed breed dog with a suspected vascular ring anomaly was presented for exercise intolerance and wheezing. Computed tomography (CT) revealed a double aortic arch. The smaller right aortic arch was successfully ligated via right 4th intercostal thoracotomy. The patient was discharged one day postoperatively and continued to have good outcome at recheck 3.5 weeks after surgery. This is the 4th documented case of double aortic arch with a successful outcome. Preoperative CT scan w...

Novel Approach to Repairing a Traumatic Aortic Arch Pseudoaneurysm Following a Fall.

Traumatic pseudoaneurysms of the aortic arch are often treated with surgical repair regardless of the lesion size or age. The authors report a simple, less invasive surgical repair in a patient who sustained blunt aortic injury following a fall.

Single Institution Experience with Hybrid Endovascular and Surgical Repairs Involving the Distal Aortic Arch.

A hybrid approach of aortic arch and descending aorta pathology, involving surgical debranching of the great vessels followed by endovascular stenting, has been increasingly used as an alternative to entirely open surgical repair. This study reviews and reports our single-centre experience with hybrid aortic arch repair over the span of a decade.

A fish bone induced aortic arch pseudoaneurysm in a male patient: A case report.

Bilateral brachiocephalic vein and superior vena cava reconstruction with an aortic allograft.

Malignant thymoma can be invasive and may at times require radical resection. Here we present a case with phrenic nerve, right upper lobe, bilateral brachiocephalic vein and superior vena cava involvement. Total venous reconstruction was carried out with a cryopreserved aortic allograft by using the aortic root, ongoing transverse arch and innominate arterial branch. The patient then had postop radiation therapy for a total of 63 Gy over 35 treatment days. Follow up imaging demonstrates no evidence of recur...

18-Fluorodeoxyglucose Positron Emission Tomography-Computed Tomography to Guide Aortic Arch Replacement in Relapsing Polychondritis.

Relapsing polychondritis (RP) is a rare progressive autoimmune disease. The cardiovascular system is rarely involved. The authors report the case of a young woman with RP aortic arch aneurysm and symptomatic cerebral vessels stenosis. A positron emission tomography-computed tomography (PET-CT) indicated areas with activity and guided the surgery. Aortic arch with proximal vessels was successfully replaced. The PET-CT may be useful to assess the risks and determine healthy zones for potential anastomotic sit...
