A 74-year-old man was admitted with the diagnosis of non-ST-elevation myocardial infarction. During right coronary angiography, a coronary artery dissection extending into the proximal ascending aorta was noticed without hemodynamic compromise. Immediate computed tomography angiography showed no evidence of dissection in the ascending aorta. Read More

Background:  Acute Type A aortic dissection (AAAD) is a surgical emergency. In patients with arch and descending aorta involvement (DeBakey Type I), a total aortic arch replacement with frozen elephant trunk (FET) could favor false lumen thrombosis and improve long-term results. The authors hereby present their experience with this technique in a single low-volume center, to assess whether the technique is feasible to treat such disease. Read More

A 75-year-old woman presented at a prior hospital with persistent cough and was treated conservatively for a thrombosed-type aortic dissection (Stanford A). One-year after discharge, follow-up computerized tomography revealed a DeBakey type II, chronic dissecting aortic aneurysm enlarged to 54 mm. She was referred to our hospital with slight edema in the face and extremities and chest radiography showed calcification around the heart. Read More

Background: In gynecological surgery to date, two distinct types of endoscopic accesses have been used to perform para-aortic lymphadenectomies: transperitoneal and extraperitoneal, each with advantages and disadvantages. We propose to develop a new mini-invasive access to perform an endoscopic extraperitoneal para-aortic lymphadenectomy via a single-port umbilical device that, to our knowledge, has never been described.

Methods: This innovative approach combines both an extraperitoneal and intraperitoneal procedure via the same umbilical incision using one single trocar. Read More

Background: During total aortic arch replacement surgery (TARS) for patients with acute type A aortic dissection, the organs in the lower body, such as the viscera and spinal cord, are at risk of ischemia even when antegrade cerebral perfusion (ACP) is performed. Combining ACP with retrograde inferior vena caval perfusion (RIVP) during TARS may improve outcomes by providing the lower body with oxygenated blood.

Methods: This study is designed as a multicenter, computer-generated, randomized controlled, assessor-blind, parallel-group study with a superiority framework in patients scheduled for TARS. Read More

Introduction: The progression of acute type A aortic dissection may cause immediate death, such that, in the event of its diagnosis, emergency surgery is indicated. Relatedly, an interhospital transfer may prolong the time from diagnosis to surgery. This study therefore investigated how interhospital transfers impact surgical outcomes for acute type A aortic dissection. Read More

Type A aortic dissection is a highly lethal condition, which warrants swift open surgical intervention to prevent death by rupture or malperfusion. Aim is to resect the proximal intimal tear and realign the dissected wall layers. We describe two patients who recently presented in our centre with a retrograde Type A intramural hematoma and a clear intimal tear distal to the left subclavian artery, that were treated in emergency by endovascular means instead of open surgery, with satisfactory short and one year follow-up results.

Objective: Decision-making concerning the extent of the repair of acute type A aortic dissection (ATAAD) includes functional and anatomical assessment of the aortic valve. We hypothesized that bicuspid aortic valve (BAV) does not impact outcome after surgery for ATAAD. We therefore evaluated the outcome after ATAAD surgery in relation to the presence of BAV, acute aortic regurgitation (AR), and surgical approach, using the Nordic Consortium for Acute Type A Aortic Dissection database.

Background And Objective: Ostial LM stenting potentially induces turbulence in the aortic wall near the LM ostium, which might be correlated with aorta dilation and dissection. We investigated through a computational fluid dynamic analysis (CFD), the presence and potential consequences of flow turbulences both in the ascending aorta and arch after a stenting left main (LM) mid shaft or distal disease.

Retrograde type A aortic dissection (RTAD) following thoracic endovascular aortic repair is a devastating complication associated with high mortality rates. In particular, a deployed endograft in a bird-beak formation in an acute curve of the aortic arch can induce injury to the fragile aortic wall, with the subsequent development of RTAD. Here, we describe an extremely rare case of RTAD caused by fracture of the bare spring of the thoracic endograft for type A aortic dissection. Read More

Objective: To evaluate the efficacy of axillary artery cannulation for early embolic stroke and operative mortality, we retrospectively compared the outcomes between patients with or without axillary artery cannulation during open aortic arch repair with circulatory arrest.

Methods: Between January 2004 and December 2017, 468 patients underwent open aortic arch repair with circulatory arrest using antegrade cerebral perfusion and were divided into 2 groups according to the site of arterial cannulation: the axillary artery (axillary group, n = 352) or another site (nonaxillary group, n = 116) groups. Embolic stroke was defined as a physician-diagnosed new postoperative neurologic deficit lasting more than 72 hours, generally confirmed by computed tomography or magnetic resonance imaging.

Background Bicuspid aortic valve ( BAV ) is the most common congenital cardiac abnormality. A thoracic aortic aneurysm ( TAA ) is present in ≈50% of BAV patients, who also have an 8-fold higher risk of aortic dissection than the general population. Because the health of the aorta is directly reflected in its stiffness and pulsatile hemodynamics, we hypothesized that measures of aortic stiffness and arterial load would be associated with TAA growth in BAV .
