Laser speckle flowgraphy (LSFG) is an ophthalmologic equipment that qualitatively detects the blood flow of the optic nerve head, which is known to be related with cerebral microcirculation. LSFG can also measure the mean blur rate, which quantitatively calculates the blood flow. We aimed to assess the utility of LSFG in the evaluation of cerebral perfusion during aortic surgery under hypothermic circulatory arrest with retrograde and antegrade cerebral perfusion. Two patients underwent total arch replacement for aneurysm...

OBJECTIVE: 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...

BACKGROUND: Kommerell diverticulum is a rare aortic arch anomaly. The indications for operative intervention and surgical strategy are still controversial. The standard surgical procedure at our institution is total aortic arch plus descending aortic replacement using anterolateral thoracotomy with partial sternotomy. The aberrant subclavian artery is reconstructed anatomically or extraanatomically. METHODS: From 2002 to 2014, 6 patients (1 woman), aged 55 to 78 years, underwent graft replacement through an anterolateral thoracotomy or anterolateral thoracotomy with a partial sternotomy approach for Kommerell diverticulum...

Sarcomatoid carcinoma of the thymus is extremely rare. An operation remains the only effective treatment for this disease. We report a case of complete resection of thymic sarcomatoid carcinoma through a total aortic arch replacement and left upper lobectomy at our institution. Our aggressive operation was very effective, and the patient has experienced no recurrence in the 3 years since his operation.

In the present study, we reported our experience with partial aortic root remodeling for root reconstruction in patients with acute type A dissection, which involves in non-coronary sinus and/or the right coronary sinus with just one trimmed Dacron graft. Between February 2001 and May 2010, we performed partial aortic root remodeling in 40 patients, who underwent emergency surgical intervention. The dissected sinuses were excised leaving a 3-5 mm rim of the aortic wall from the attached aortic valve cusps. A short piece (4-5 cm) of collagen coated woven polyester vascular prosthesis was trimmed with one or two "tongues" to reconstruct the non-coronary sinus and/or the right coronary sinus, but without using separated patches...

BACKGROUND: This study assessed the early and long-term results of arch operations performed after a prior aortic operation. METHODS: From 1994 to 2014, 154 consecutive patients (mean age, 59.7 years) underwent an aortic arch repair, after a previous aortic operation, at our institution. Antegrade selective cerebral perfusion was used in all cases. Chronic postdissection aortic aneurysm (87 [56.5%]) and degenerative aneurysm (43 [27.9%]) represented the most common indications for surgical intervention...

Diagnosis of aortic dissection complicating cerebral ischemic stroke is difficult. A 60-year-old patient presented at an emergency department of a hospital with a sudden development of left-sided weakness, but without chest pain. During administration of recombinant tissue plasminogen activator with diagnosis of cerebral infarction, he developed symptomatic hypotension and was transferred to our hospital. His chest computed tomography revealed Stanford type A aortic dissection. Replacement of the ascending aorta and aortic arch was successfully performed on the 4th day...

REVIEW
Edward P Chen, Bradley Graham Leshnower
Surgical treatment of aortic arch disease is a technically challenging procedure that requires complex circulation management strategies involving the use of hypothermic circulatory arrest. The definition of hypothermia has evolved with comfort and surgical adjuncts. This review describes the various circulation and temperature management strategies used during hemiarch and total arch replacement.

Hybrid aortic arch repair is increasingly used for the management of aortic arch aneurysm. Pseudoaneurysm is a newly described late complication of this procedure. A 57-year-old man underwent emergent supra-aortic debranching and aortic arch stent grafting after rupture of an arch aneurysm. Three years later, the patient presented with a pseudoaneurysm at the junction between the stent graft's proximal landing zone and the origin of the debranching graft. At reoperative repair, the proximal stent graft had eroded through the aortic wall at the junction of the endograft proximal landing zone and the proximal anastomosis of the debranching graft...

Ascending aortic aneurysms arising from the native aorta following cardiac transplantation are rare. We report two patients who developed aneurysms of the native ascending aorta requiring surgical repair post-transplantation. Both patients underwent ascending and hemi-arch replacement and recovered uneventfully. Heart transplant patients with pre-existing aortic dilation/ectasia may display more rapid aneurysmal growth compared to non-transplant patients. Therefore close observation is warranted in these patients...

BACKGROUND: Because increased age is a strong independent predictor of mortality and morbidity, surgery for octogenarians with Stanford type A aortic dissection (AAD) may be avoided.Methods and Results:From 2005 to 2015, 158 patients underwent surgical repair for AAD via a median sternotomy. We compared 24 (15.2%) octogenarians (83±3 years) with 134 (84.8%) patients aged ≤79 years (62±13 years), based on retrospectively collected clinical data. Octogenarians were predominantly female (79...

A 78-year-old man with a Kommerell diverticulum and aberrant right subclavian artery was admitted for thoracic pain and severe malnutrition due to esophageal compression. We performed an atypical surgical procedure including extra-anatomical debranching and direct aortic repair, trying to avoid deep hypothermic circulatory arrest and shorten the cardiopulmonary bypass time.

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)...
