Objective: To report the authors' experience in performing thoracic endovascular aortic repair (TEVAR) for zone 2 lesions after traumatic aortic injury (TAI). Materials and Methods: This retrospective review included 10 patients who underwent zone 2 TEVAR after identification of aortic isthmus injury by CT angiography (CTA) upon arrival at the emergency room of a regional trauma center from 2016 to 2019. Patients were classified into two groups: those who underwent left subclavian artery (LSA) embolization concurrently with the main TEVAR procedure, and those in whom LSA embolization was not performed during the main procedure, but was planned as a bailout treatment if type II endoleak was noted on follow-up CTA images. Pre-procedural and procedure-related factors and post-procedure prognosis were compared between the groups. Results: There were no differences in pre-procedural factors, occurrence of endoleaks, and post-procedure prognosis (including mortality) between patients in the two groups. The duration of the procedure was shorter in the non-LSA embolization group (61 minutes vs. 27 minutes, p = 0.012). During follow-up, type II endoleak did not occur in either group. Conclusion: Delaying preventative LSA embolization until stabilization of the patient would be desirable when performing zone 2 TEVAR for TAI, in the absence of endoleak on the completion aortography image taken after complete deployment of the stent graft.

Turner syndrome, also described as 45, X, may present with most serious cardiovascular anomalies including risk of aortic dissection and rupture. In emergency situation, management for aortic dissection with complicated anatomy accompanying vascular anomaly is challenging. Here, we report a rare case of ruptured type B aortic dissection with aberrant subclavian artery and partial anomalous pulmonary venous connection in a Turner syndrome. Through right carotid-subclavian artery bypass and thoracic endovascular aortic repair, successful hybrid endovascular management correlated with a favorable result in this emergency situation.

Chylothorax is a rare postoperative complication of a thoracic surgical procedure. Here, we report a case of chylothorax after thoracic endovascular aortic repair with debranching for the distal arch aneurysm of the aorta. First, the patient was treated by a medical method (nil per os, fat-free diet, and octreotide), but this method failed. The patient strongly refused surgical treatment. Therefore, we tried to occlude the thoracic duct by lymphangiography Lipiodol, and this line of treatment was successful.

Background: Endovascular aneurysm repair (EVAR) has dramatically changed the management of abdominal aortic aneurysms (AAAs) as the number of open aneurysm repairs have declined over time. This report compares AAA-related demographics, operative data, complications, and mortality after treatment by open aneurysm repair or EVAR. Methods: We retrospectively reviewed 136 patients with AAAs who were treated over an 8-year time period with open aneurysm repair or EVAR. Results: The mean age of the EVAR group was higher than that of the open repair group (p=0.001), and hospital mortality did not differ significantly between groups (p=0.360). However, overall survival was significantly lower in the EVAR group (p=0.033). Conclusion: Although EVAR is the primary treatment modality for elderly patients, it would be ideal to set slightly more stringent criteria within the anatomical guidelines contained in the instructions for use of the EVAR device when treating younger patients.

Background: The aim of this study was to report our early experiences with the endovascular repair of ruptured descending thoracic aortic aneurysms (rDTAAs), which are a rare and life-threatening condition. Methods: Among 42 patients who underwent thoracic endovascular aortic repair (TEVAR) between October 2010 and September 2015, five patients (11.9%) suffered an rDTAA. Results: The mean age was $72.4{\pm}5.1years$, and all patients were male. Hemoptysis and hemothorax were present in three (60%) and two (40%) patients, respectively. Hypovolemic shock was noted in three patients who underwent emergency operations. A hybrid operation was performed in three patients. The mean operative time was $269.8{\pm}72.3minutes$. The mean total length of aortic coverage was $186.0{\pm}49.2mm$. No 30-day mortality occurred. Stroke, delirium, and atrial fibrillation were observed in one patient each. Paraplegia did not occur. Endoleak was found in two patients (40%), one of whom underwent an early and successful reintervention. During the mean follow-up period of $16.8{\pm}14.8months$, two patients died; one cause of death was a persistent type 1 endoleak and the other cause was unknown. Conclusion: TEVAR for rDTAA was associated with favorable early mortality and morbidity outcomes. However, early reintervention should be considered if persistent endoleak occurs.

Thoracic endovascular aortic repair (TEVAR) has emerged as an effective therapy for a variety of thoracic aortic pathologies. However, various types of endoleak remain a major concern, and its treatment is often challenging. We report a case of type I endoleak occurring 19 months after zone II hybrid TEVAR. The endoleak was successfully repaired by the frozen elephant trunk technique, without removal of a previous stent graft, combined with ascending aorta and total arch replacement.

An 87-year-old man presented with a saccular aneurysm at the proximal descending thoracic aorta. As computed tomography revealed a shaggy aorta, we planned hybrid thoracic endovascular aortic repair (TEVAR) with embolic protection devices (EPDs) in both internal carotid arteries to prevent a cerebrovascular accident. We inserted an Emboshield NAV⁶ Embolic Protection System (Abbott Vascular, Abbott Park, IL, USA) into both internal carotid arteries before performing the TEVAR procedure. The patient was discharged from the hospital on postoperative day 4 without any neurological complications.

Background: Endovascular aortic aneurysm repair (EVAR) has come into use and been widely extended because of the low complication rate and less-invasiveness. This article aimed to describe our experience in the treatment of abdominal aortic aneurysm with EVAR. Materials and Methods: A retrospective review was conducted for the 22 patients who underwent EVAR in a single hospital December 2001 to June 2009. Results: The mean age of the patients was $68.5{\pm}7.6$ years. There were several risk factors and comorbidities in 20 patients (90.9%). The mean diameter of the aortic aneurysms was $61.2{\pm}12.9$ mm. The mean length, diameter, and angle of the aneurysmal neck were $30.5{\pm}15.5$ mm, $24.0{\pm}4.5$ mm, and $43.9{\pm}16.0^{\circ}$, respectively. The mean follow-up period of the patients was $28.8{\pm}29.5$ months. The 30-day postoperative mortality was none. Seven patients (31.8%) had endoleaks during the hospital stay and three patients (13.6%) had endoleaks during the follow-up period. One patient (4.5%) died due to a ruptured aortic aneurysm. The cumulative patient survival rates were 88.2%, 88.2%, and 70.6% at 1, 3, and 5 years of follow-up, respectively. Conclusion: EVAR is currently a safe, feasible procedure for high risk patients with abdominal aortic aneurysm because of low postoperative complication and mortality if patients are selected properly and followed up carefully.

The usual treatment for aortic aneurysms is surgical replacement with a prosthetic graft; however the associated morbidity and mortality rates must be considered. Endovascular placement of self-expandable stent-graft is a safe noninvasive treatment that can be an alternative to the surgical repair, the postoperative course of the 2 cases of thoracoabdominal aortic aneurysms was uneventful and no complication has been associated with the stent-graft during the 17 months and 5 months follow-up studies,.

A stent graft has been accepted as an alternative method for treating aortic diseases or to reduce the extent of surgery. We report here on a one-stage Management of Ascending Aorta Replacement and Percutaneous Endovascular Repair for the seperate aneurysmal lesions on the ascending and descending aorta.
