OBJECTIVES: In patients with severe carotid artery stenosis, the anatomy of their Type III aortic arch increases the difficulty and complication rates during carotid artery stenting because of its tortuosity and sharp angulation for cannulation as well as the unstable support of the guidewire for shuttle sheath delivery. METHODS: We demonstrate a novel technique to overcome these challenges, namely the creation of stable innominate artery access by inserting a through-and-through body floss wire from the right brachial artery to the femoral artery...

OBJECTIVES: Iliofemoral arteries have been the preferred access for transcatheter aortic valve replacement (TAVR). When these arteries are too small, calcified or tortuous, an alternative access must be considered. Transinnominate (TI) access is an extrathoracic approach that does not require manipulation of major neurovascular structures or the apex. The aim of this study is to evaluate the efficacy and safety of TI TAVR as an alternative access in patients with severe aortic stenosis not amenable to a transfemoral approach...

We present a rare case of a branching anomaly of the aortic arch that resulted in wheezing and dyspnoea. The patient was a 60-year-old male with severe wheezing from babyhood, originally diagnosed with severe bronchial asthma. On auscultation, the inspiratory and expiratory wheezes appeared when the patient leaned forward. He also had difficulty in swallowing solid mass. Tests for airway reversibility and hyperresponsiveness were negative, and asthma treatment was ineffective. He had a right aortic arch. A barium oesophagogram and endoscopic examination indicated narrowing of the oesophagus from behind...

A 60-year-old female patient underwent emergency cadaveric liver transplantation. During the insertion of the pulmonary artery catheter (PAC) through the left innominate vein, advancement of the catheter was not successful and a knot occurred. An interventional radiologist performed antegrade rigid wire insertion into the PAC and succeeded in loosening the knot in the vessel. We report the successful removal of a knot through intervention without additional invasive procedures in a hemodynamically unstable patient with a coagulopathy...

OBJECTIVE: We evaluated images of patients undergoing a thoracic endovascular aortic repair procedure using two reference points as a means for differentiating stent graft migration from aortic elongation. Conventional standards define migration of a stent graft as an absolute change in the distance from the distal graft ring to a distal landmark ≥10 mm compared with a baseline measurement. Aortic elongation occurs over time in both healthy individuals and patients with aortic disease...

PURPOSE: Suprasternal transcatheter aortic valve replacement offers patients, with unsuitable femoral artery anatomy, an alternative to transapical, direct aortic, and subclavian approaches. DESCRIPTION: The Transit System (Aegis Surgical, Galway, Ireland) enables transcatheter aortic valve replacement directly into the ascending aorta or innominate artery through a small, suprasternal incision. The valve introducer sheath is inserted through a standard pursestring suture, which facilitates secure arterial closure...

AIMS: Incidence and determinants of restenosis and adverse events after endovascular management (PTA±stent) of the subclavian/innominate artery (SA/IA) stenosis/occlusion remain unclear due to relatively short-term follow-up or limited size of prior studies. This large-scale, long-term prospective study investigated safety, efficacy, and prognosis after SA/IA PTA±stent. METHODS AND RESULTS: The study involved 411 consecutive patients with symptomatic SA/IA stenosis/occlusion; 393 after successful PTA±stent were followed annually for up to 16 (minimum 1) years...

Cannulation and perfusion in extensive aortic dissection involving the neck and femoral vessels is challenging in view of false lumen cannulation and attendant malperfusion syndromes. Although a number of methods have been described, our technique of cannulation and perfusion through right atrial-to-left atrial bypass and innominate artery transection ensures adequate brain perfusion and visceral organ true lumen perfusion during the entire duration of cardiopulmonary bypass. This procedure can be applied to all varieties of extensive type A aortic dissections involving the neck and femoral vessels...

A 27-year-old man was admitted with a penetrating injury at the mid-manubrium. Computed tomographic (CT) angiography showed a filling defect in the aortic arch. This was evaluated as a sign of injury and the patient underwent an emergency operation. No active bleeding or clot was found in the mediastinum during the operation. The laceration point was between the innominate and the left carotid artery posteriorly. The injury was approached using hypothermic circulatory arrest. Aortotomy and exploration showed a 2-cm-long full-thickness aortic injury with an overlying clot...

Homografts and synthetic grafts are used in surgery for congenital heart disease (CHD). Determining these materials' mechanical properties will aid in understanding tissue behavior when subjected to abnormal CHD hemodynamics. Homograft tissue samples from anterior/posterior aspects, of ascending/descending aorta (AA, DA), innominate artery (IA), left subclavian artery (LScA), left common carotid artery (LCCA), main/left/right pulmonary artery (MPA, LPA, RPA), and synthetic vascular grafts, were obtained in three orientations: circumferential, diagonal (45 deg relative to circumferential direction), and longitudinal...

OVERVIEW: To describe a new endovascular procedure for acute type A aortic dissection (TAAD) repair. METHODS: Between 2013 and 2016, 12 patients (average age 54±9.6 years; 10 men) with acute TAAD (mean EURO score 11.4%±3.2%, range 5-17) and unfit for surgery underwent thoracic endovascular aortic repair (TEVAR) with 2 periscope grafts to preserve blood supply to supra-aortic branches plus bypass grafting as needed. If the ascending aorta was dilated to >40 mm, sternotomy was performed to wrap the ascending aorta and reduce its diameter to accommodate the aortic stent-grafts...

The endovascular realm has steadily increased its footing in the treatment of the aorta and all of its territories since the foundational case in 1990 by Parodi. The aortic arch, however, continues to be one of the last bastions for treatment via open surgery, which remains the gold standard. Significant comorbidity and prior cardiac surgery prevent open surgery from being the only preferred option, allowing novel endovascular procedures to be considered. Since 1999, more advanced endovascular systems have been created by companies such as Cook Medical, Bolton Medical, Medtronic, Endospan, Gore Medical, and, recently, Kawasumi...

BACKGROUND: Symptomatic innominate artery stenosis presenting as hemodynamic bilateral cerebral ischemia is uncommon. We present a rare case of the severe stenosis of the origin of an innominate artery and severe stenosis of bilateral internal carotid artery that induced hemodynamic cerebral ischemia after ipsilateral axillary artery-bilateral femoral artery bypass and was treated with stent replacement of the innominate artery and right internal carotid artery. CASE REPORT: A 64-year-old woman who previously had undergone right axillary artery-bilateral femoral artery anastomosis for abdominal aorta high obstruction had been suffering from chronic dizziness and so visited our department...

We describe an alternate technique to perform a replacement of the aortic hemiarch without the need for hypothermic circulatory arrest by axillary cannulation and arch vessel isolation. In 2015, 3 patients underwent hemiarch reconstructions for ascending aortic aneurysms that extended into the arch. Each was performed using right axillary cannulation, isolation and clamping of the innominate artery with isolation, and tangential clamping of the aorta distal to the innominate. There were no neurologic events and no perioperative morbidity or mortality...
