BACKGROUND: Information on the growth rate of the diameter of the residual dissected supra-aortic trunk after surgical repair of type A aortic dissection is limited. METHODS: We retrospectively reviewed 95 consecutive postsurgical patients with type A aortic dissection (acute, 91; chronic, 4) between 2005 and 2016 who were followed up with computed tomography. The diameter of the residual dissected supra-aortic trunk was measured by axial images and multiplanar reformatting, and the growth rate was calculated...

BACKGROUND: We present the possible utility of computational fluid dynamics in the assessment of thrombus formation and virtual surgical planning illustrated in a patient with aortic thrombus in a kinked ascending aortic graft following thoracic endovascular aortic repair. METHODS: A patient-specific three-dimensional model was built from computed tomography. Additionally, we modeled 3 virtual aortic interventions to assess their effect on thrombosis potential: (1) open surgical repair, (2) conformable endografting, and (3) single-branched endografting...

The authors analysed herein the results of examination and surgical treatment of patients presenting with Takayasu aortoarteritis with an isolated lesion of the aortic arch branches. Discrepancy between the degree of ischaemia, dissemination, and localization of lesions, as well as ambiguity of neurological manifestations suggests large compensatory possibilities of the cerebral circulation in this disease. The revealed peculiarities of lesions of the brachiocephalic arteries characteristic the pathology concerned were as follows: high incidence of lesions of subclavian arteries (mainly in the second and third segments), utterly rare involvement of the brachiocephalic trunk, a stenosisng pattern of lesion of carotid arteries with predominant localization in the common carotid artery, not involving it into the process of bifurcation...

BACKGROUND: The aim of this study is to describe a total endovascular aortic repair with branched and fenestrated endografts in a young patient with Marfan syndrome and a chronic aortic dissection. Open surgery is the gold standard to treat aortic dissections in patients with aortic disease and Marfan syndrome. METHODS: In 2000, a 38-year-old man with Marfan syndrome underwent open ascending aorta repair for an acute type A aortic dissection. One year later, a redo sternotomy was performed for aortic valve replacement...

BACKGROUND: Stanford type A acute aortic dissection (A-AAD) extends to the brachiocephalic branches in some patients. After ascending aortic replacement, a remaining re-entry tear in the distal brachiocephalic branches may act as an entry and result in a patent false lumen in the aortic arch. However, the effect of brachiocephalic branch re-entry concomitant with A-AAD remains unknown.Methods and Results:Eighty-five patients with A-AAD who underwent ascending aortic replacement in which both preoperative and postoperative multiple-detector computed tomography (MDCT) scans could be evaluated were retrospectively studied...

PURPOSE: To describe the combined use of a tubular stent-graft for the ascending aorta and an inner-branched arch stent-graft for patients with acute type A aortic dissection. TECHNIQUE: The technique to deploy these modular, custom-made stent-grafts is demonstrated in 2 patients with acute DeBakey type I aortic dissections and significant comorbidities precluding open surgery. Both emergent procedures were made possible by the availability of suitable devices manufactured for elective repair in other patients...

The patchy distribution of atherosclerosis within arteries is widely attributed to local variation in haemodynamic wall shear stress (WSS). A recently-introduced metric, the transverse wall shear stress (transWSS), which is the average over the cardiac cycle of WSS components perpendicular to the temporal mean WSS vector, correlates particularly well with the pattern of lesions around aortic branch ostia. Here we use numerical methods to investigate the nature of the arterial flows captured by transWSS and the sensitivity of transWSS to inflow waveform and aortic geometry...

Congenital variants and anomalies of the aortic arch are important to recognize as they may be associated with vascular rings, congenital heart disease, and chromosomal abnormalities, and can have important implications for prognosis and management. The purpose of this article is to review cross-sectional imaging techniques used in the evaluation of the aortic arch, describe the embryology and anatomy of the aortic arch system, discuss aortic arch variants and anomalies, and review other malformations of the aortic arch, including interrupted aortic arch, hypoplastic aortic arch, and aortic coarctation...

Thoracic endovascular aortic repair (TEVAR) offers a less invasive treatment for aortic arch aneurysms. Clinical challenges arise when there is inadequate proximal landing for zone 1 TEVAR, such that a median sternotomy with total aortic debranching is required before stent deployment. The chimney technique was reported as an alternative approach to stent the arch branches and avoid sternotomy, but it was still associated with considerable chance of a type IA endoleak. We report a case of aortic arch aneurysm with an inadequate proximal landing for zone 1 TEVAR that was treated with debranching of head and neck vessels followed by TEVAR and preemptive and targeted coil embolization of the arch aneurysmal sac...

OBJECTIVE: Despite technical advances of fenestrated and branched endografts, endovascular exclusion of aneurysms involving renal, visceral, and/or supra-aortic branches remains a challenge. In situ fenestration (ISF) of standard endografts represents another endovascular means to maintain perfusion to such branches. This study aimed to review current indications, technical descriptions, and results of ISF. METHOD: A review of the English language literature was performed in Medline databases, Cochrane Database, Web of Science, and Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines...

W Anthony Lee
The aortic arch is one of the most anatomically complex segments of the thoracoabdominal aorta due the plurality of vital branch configurations, intrinsic and highly variable three-dimensional curvature, and involvement in a variety of thoracic aortic pathologies, such as aneurysmal degeneration, penetrating ulcer, and media wall dissection. Pathologies that extend the repair proximal to the left common carotid artery require more complex branch vessel management beyond a carotid-subclavian bypass. This article will review the current status of branched aortic arch endografts...

A tortuous common carotid artery poses a high risk of injury during tracheotomy. Preoperative diagnosis is therefore important to avoid serious complications. We found four cases of tortuous common carotid artery during an anatomical dissection course for students. The first case was a 91-year-old woman who had bilateral tortuous common carotid arteries without arteriosclerosis. Case 2 was a 78-year-old woman who had bilateral tortuous common carotid arteries without arteriosclerosis. Case 3 was an 86-year-old woman who died from bladder cancer and who also had a right tortuous common carotid artery without arteriosclerosis...

OBJECTIVES: Complete vascular rings are rare and cause tracheoesophageal compression. Following surgical division, some patients have persisting tracheomalacia. We aim to assess the long-term outcomes of complete vascular ring division. METHODS: All patients (n = 132) who underwent surgical division of a complete vascular ring between 1978 and 2014 were identified from the hospital database and retrospectively reviewed. RESULTS: Complete vascular rings consisted of a double aortic arch (n = 80), right aortic arch with an aberrant subclavian artery and left ligamentum arteriosum (n = 50), right aortic arch with mirror image branching and left ligamentum arteriosum (n = 1), and a left aortic arch with right descending aorta and right ligamentum arteriosum (n = 1)...

BACKGROUND: Stent grafting is a therapeutic option for patients who are unable to undergo urgent surgical repair of ascending aortic dissections. However, follow-up regarding outcomes is limited. OBJECTIVES: This study reports mid-term outcomes with endovascular repair for ascending aortic dissections in patients deemed high risk for open repair. METHODS: Between May 1, 2009 and January 31, 2011, 15 ascending aortic dissection patients (ages 45 to 78 years) ineligible for direct surgical repair underwent endovascular repair (1 acute dissection, 7 subacute dissections, and 7 chronic dissections) and were closely followed up for a median of 72 months (range 61 to 81 months)...

We review the operative techniques of aortic arch replacement. Aortic arch replacement presents several formidable challenges, as it requires arresting the circulation to the body and replacement of the brachiocephalic vessels with special consideration for protecting the central nervous system. Perfusion strategies, selective antegrade cerebral perfusion, and operative graft selection are key elements in aortic arch replacement surgery. Standard approaches include the island technique, the branched graft technique, and the "Spielvogel" trifurcated graft technique-each having its own advantages...

PURPOSE: To evaluate risk factors for early (<30 days) type I endoleak following thoracic endovascular aortic repair (TEVAR). METHODS: A retrospective study was conducted of 439 consecutive patients (mean age 74.0±10.0 years; 333 men) who underwent TEVAR at a single center between June 2006 and June 2013. Pathologies included 237 aortic arch aneurysms and 202 descending thoracic aortic aneurysms (dTAA). Maximum TAA diameter was 63.6±13.7 mm. Among the distal aortic arch aneurysms, 124 required coverage of the left subclavian artery (LSA), while the remaining 113 arch aneurysms had debranching (n=40), the chimney technique (n=52), and a branched stent-graft (n=13)...

Tracheostomy is a common procedure in head and neck surgery and emergency medicine to secure a patent airway. Surgeons should always be aware of anatomical variants of the branches of the aortic arch, which could lead to life-threatening complications. Open tracheostomy is the safest emergency procedure.

We describe an aortic arch anomaly consisting of the origin of the left subclavian artery as the fourth branch and the right subclavian artery as the first branch off the aortic arch with crisscrossing of these two arteries anterior to the trachea without clinical consequences. This anomaly, to our knowledge, has not been reported previously.

Hybrid stage I palliation combines cardiothoracic surgery and interventional transcatheter procedures for treatment of hypoplastic left heart syndrome. The approach is an alternative to the Norwood procedure, the traditional first stage of surgical palliation. Hybrid stage I palliation involves placing bilateral branch pulmonary artery bands and a patent ductus arteriosus stent through a median sternotomy, performed without cardiopulmonary bypass. The purpose of the bands is to control blood flow to the lungs and protect the pulmonary bed while the stent sustains systemic cardiac output...
