Abstract
The present study reported the outcomes of different treatments for innominate artery (IA) atherosclerotic stenosis or occlusion. We performed a systematic review of the literature (4 database searched; last search February 2022), including articles with ≥5 patients. We performed meta-analyses of proportions for different postoperative outcomes. Fourteen studies were included (656 patients; 396 underwent surgery, 260 endovascular procedures). IA lesions were asymptomatic in 9.6% (95% CI 4.6-14.6). Overall estimated technical success (TS) rate was 91.7% (95% CI 86.9-96.4); weighted TS rate was 86.8% (95% CI 75-98.6) in the surgical group (SG), 97.1% (95% CI 94.6-99.7) in the endovascular group (EG). Postoperative stroke in SG was 2.5% (95% CI 1-4.1) and 2.1% in EG (95% CI .3-3.8). Overall, 30-day occlusion was estimated .9% (95% CI 0-1.8) in SG and .7% (95% CI 0-1.7) in EG. Thirty-day mortality was 3.4% (95% CI .9-5.8) in SG and .7% (95% CI 0-1.7) in EG. Estimated mean follow-up after intervention was 65.5 months (95% CI 45.5-85.5) in SG and 22.4 months (95% CI 14.72-30.16) in EG. During follow-up, restenosis in SG were 2.8% (95% CI .5-5.1) and 16.6% (95% CI 5- 28.1) in EG. In conclusion, the endovascular approach seems to offer good short to mid-term outcomes, but with a higher rate of restenosis during follow-up.

Cerebral Perfusion and Neuromonitoring during Complex Aortic Arch Surgery: A Narrative Review. J Clin Med 2023; 12:jcm12103470. [PMID: 37240576 DOI: 10.3390/jcm12103470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 04/14/2023] [Accepted: 05/05/2023] [Indexed: 05/28/2023] Open
Abstract
Complex ascending and aortic arch surgery requires the implementation of different cerebral protection strategies to avoid or limit the probability of intraoperative brain damage during circulatory arrest. The etiology of the damage is multifactorial, involving cerebral embolism, hypoperfusion, hypoxia and inflammatory response. These protective strategies include the use of deep or moderate hypothermia to reduce the cerebral oxygen consumption, allowing the toleration of a variable period of absence of cerebral blood flow, and the use of different cerebral perfusion techniques, both anterograde and retrograde, on top of hypothermia, to avoid any period of intraoperative brain ischemia. In this narrative review, the pathophysiology of cerebral damage during aortic surgery is described. The different options for brain protection, including hypothermia, anterograde or retrograde cerebral perfusion, are also analyzed, with a critical review of the advantages and limitations under a technical point of view. Finally, the current systems of intraoperative brain monitoring are also discussed.

Case report: A hybrid open and endovascular approach for repairing a life-threatening innominate artery dissection using the simultaneous kissing stent technique. Front Neurol 2023; 14:1149236. [PMID: 37213896 PMCID: PMC10196481 DOI: 10.3389/fneur.2023.1149236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 04/12/2023] [Indexed: 05/23/2023] Open
Abstract
Managing acute innominate artery (IA) dissection associated with severe stenosis is challenging due to its rarity, possible complex dissection patterns, and compromised blood flow to the brain and upper extremities. This report describes our treatment strategy for this challenging disease using the kissing stent technique. A 61-year-old man had worsening of an acute IA dissection secondary to an extension of a treated aortic dissection. Four possible treatment strategies for kissing stent placement were proposed based on different approaches (open surgical or endovascular) and accesses (trans-femoral, trans-brachial, or trans-carotid access). We chose to place two stents simultaneously via a percutaneous retrograde endovascular approach through the right brachial artery and a combined open surgical distal clamping of the common carotid artery with a retrograde endovascular approach through the carotid artery. This hybrid approach strategy highlights the three key points for maintaining safety and efficacy: (1) good guiding catheter support is obtainable through retrograde, rather than antegrade, access to the lesion, (2) concomitant cerebral and upper extremity reperfusion is guaranteed by placing kissing stents into the IA, and (3) peri-procedural cerebral emboli are prevented by surgical exposure of the common carotid artery with distal clamping.

Prevention of Tracheo- Innominate Artery Fistula Formation as a Complication of Tracheostomy: Two Case Reports. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9111603. [PMID: 36360331 PMCID: PMC9688328 DOI: 10.3390/children9111603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 10/08/2022] [Accepted: 10/21/2022] [Indexed: 01/25/2023]
Abstract
Tracheo-innominate artery fistula (TIF) is a rare complication of tracheostomy and refers to the formation of a fistula between the trachea and innominate artery. Because TIF is fatal, prevention rather than treatment is very important. Here we report the cases of two high-risk patients who underwent tracheostomy, and in whose cases attempts were made to lower the risk of TIF. In the first patient who developed a chest deformity with Duchenne muscular dystrophy, a tracheostomy was performed with a high-level (cricothyroid level) approach compared with the standard tracheostomy. In the second patient, the thoracic cage was relatively small due to a giant omphalocele, and the risk of a fistula forming was decreased by wrapping the innominate artery with an opened polytetrafluoroethylene vascular graft after resolving crowding of the intrathoracic cavity by total thymectomy. There was no TIF occurrence at the outpatient follow-up in either case. We expect that our approaches may be effective intervention measures for preventing TIF.

Abstract
PURPOSE The purpose of this study was to evaluate early and mid-term results of non-standard management of the supraaortic target vessels with the use of the inner branch arch endograft in a single high-volume center. MATERIAL AND METHODS A single-center retrospective study including all patients undergoing implantation of an inner branch arch endograft from December 2012 to March 2021, who presented a non-standard management of the supraaortic target vessels (any bypass other than a left carotid-subclavian or landing in a dissected target vessel). Technical success, mortality, reinterventions, endoleak (EL), and aortic remodeling at follow-up were analyzed. RESULTS Twenty-four patients were included. In 17 (71%) cases, the non-standard management was related to innominate artery (IA) compromise (12 with IA dissection, 2 with short IA, 2 with short proximal aortic landing zone that required occlusion of IA, 1 with occluded IA after open arch repair). Two (8%) cases were related to an aberrant right subclavian artery (RSA), 1 patient (4%) due to the concomitant presence of a left vertebral artery (LVA) arising from the arch and an occluded left subclavian artery (LSA), and another patient presented with an occluded LSA distal to a dominant vertebral artery. Three (13%) cases were exclusively related to management in patients with genetic aortic syndromes. Twenty (83%) patients had a previous type A aortic dissection. Ten (42%) patients presented a thoracic or thoracoabdominal aortic aneurysm and 8 (33%) patients an arch aneurysm, 6 of them associated to false lumen (FL) perfusion. There were 2 (8%) perioperative minor strokes, and 1 patient with perioperative mortality. Seven patients presented an early type I endoleak, all resolved at follow-up. Seven patients required reinterventions during follow-up (7 reinterventions related to continuous false lumen perfusion, 3 related to Type Ia endoleak, 2 related to surgical bypass). All patients who presented with FL perfusion had complete FL thrombosis at follow-up. No patient presented aneurysm growth at follow-up. CONCLUSIONS The use of the inner branch arch endograft with a non-standard management of the supraaortic target vessels is a possible option. Despite a high reintervention rate, regression or stability of the aneurysmal diameter was achieved in all the patients with follow-up.

Abstract
PURPOSE Acute thromboembolic disease of the innominate artery (IA) poses a unique set of therapeutic challenges, owing to its contribution to both the cerebral and upper extremity circulation, and risks of distal embolization via the carotid and subclavian arteries, respectively. Herein, we present a 74-year-old female who presents with acute IA thrombus treated successfully with right axillary and common carotid exposure and aspiration catheter-directed mechanical thrombectomy (CDT). Furthermore, an emerging use of CDT and its application in acute thromboembolism are outlined. CASE REPORT A 74-year-old female with history of right lung transplant for pulmonary fibrosis with severe pulmonary hypertension, and stage IIIA left lung adenocarcinoma status post left lower lobectomy undergoing adjuvant chemotherapy presented with acute IA thrombus and right-sided stroke. She was treated successfully with right axillary and common carotid exposure and aspiration CDT. Computed tomography angiography performed 1 month postoperatively confirmed patent IA with no evidence of residual or recurrent thrombus. CONCLUSION There are currently no standard guidelines on the management of acute IA thromboembolism, with mostly individual cases reported in the literature describing this rare entity. Nevertheless, this unique clinical entity mandates expeditious diagnostic and therapeutic approaches in order to avoid permanent neurologic deficits from distal embolization. Our case demonstrates that aspiration CDT may be an effective treatment modality for patients with acute IA thrombus.

Abstract
INTRODUCTION Mucopolysaccharidosis (MPS) type IVA usually results in airway obstruction due to thoracic cage deformity and crowding of intrathoracic structures, causing tracheal compression by the tortuous innominate artery. OBJECTIVES To offer an alternative and effective method in dealing with the challenged deformity of the airway in patients with MPS type IVA. METHODS We present 3 patients with MPS type IVA who underwent airway stenting using Montgomery® T-tube stents. Three-dimensional reconstructed computed tomography was essential to design the T-tube and evaluate the anatomical relationship between the innominate artery and the trachea. The Y-shaped Montgomery® Pediatric Safe-T-Tube™ is more suitable for MPS type IVA. Regular follow-ups using fiberoptic bronchoscopy are necessary to evaluate the complications. RESULTS All 3 patients had good outcomes during the follow-ups until present, despite the complication of granulation formation, which was resolved by revising the limbs of the T-tube. CONCLUSIONS T-tube stents placed below the vocal cord may restore airway patency and preserve laryngeal function, including respiration, phonation, and swallowing, in patients with MPS type IVA.

Abstract
Here we describe a case of recurrent ischemic strokes due to fragile innominate artery plaque successfully treated using endovascular stent grafting. An 80-year-old man presented with a history of recurrent strokes that were refractory to medical treatment. Computed tomography and magnetic resonance images of the thorax revealed a gross intramural plaque in the innominate artery. He was successfully treated using endovascular stent grafting. An AFX stent graft device was used to prevent further embolic strokes. The AFX stent graft has a unique endoskeleton design with a thin-walled expanded polytetrafluoroethylene fabric—known as active sealing structure—attached to the implant. Postoperatively, the patient has experienced no recurrent strokes in over 2 years of follow-up. The stent grafting procedure could be an optimal treatment option for treating fragile innominate artery plaques.

Abstract
Innominate artery (IA) injury is a rare entity with most patients dying before reaching the hospital. While open surgery remains the standard treatment, the endovascular approach is attractive as it may reduce perioperative morbidity and mortality. We report a case of IA blunt injury extending to the subclavian artery with pseudoaneurysm formation successfully treated with covered stenting of IA and its bifurcation. A 49-year-old male was admitted after suffering multiple trauma due to a high energy impact motorcycle crash. In the emergency room, the patient was hypotensive with a Glasgow coma score of 15. On physical examination, he had right peri-orbital ecchymosis, left otorrhagia and an open patella fracture. The computed tomographic angiography (CTA) revealed enlargement of the mediastinum and a 29 mm pseudoaneurysm involving the right brachiocephalic trunk and its bifurcation. Under general anesthesia, a covered balloon-expandable stent (CBES) was then placed in the IA followed by kissing stent of its bifurcation with an additional 2 covered balloon-expandable stents. Final subtraction angiography demonstrated complete pseudoaneurysm exclusion and stent patency without additional complications. No neurologic deficits or other intervention-related complications were found in the postoperative period. At 10 months follow-up, the patient remained asymptomatic and with palpable distal pulses. Endovascular management of IA injury may provide a good alternative to open surgery with low perioperative morbidity and mortality.

Abstract
OBJECTIVE Despite advancements in transcatheter aortic valve replacement (TAVR) technology, alternate access strategies are still required when transfemoral access is unsuitable. In these often anatomically complex group of patients, we sought to evaluate the safety and feasibility of suprasternal transinnominate (TI) artery access for TAVR. METHODS At our institution, 652 patients underwent TAVR from November 2011 through February 2020. Of these, 23 patients underwent TI TAVR via a 5-cm suprasternal incision without special instrumentation. Outcomes of interest were technical considerations, postoperative complications, and perioperative recovery in relation to established access strategies. RESULTS The mean Society of Thoracic Surgeons risk score was 8.6 ± 4.2 and the average age was 75 ± 8. All patients underwent TI TAVR using a self-expanding (12), or balloon-expandable (11) transcatheter heart valve. Average postoperative stay was 2 ± 0.7 days (range 2 to 4) with most 20/23 (87%) being discharged to home. There was no 30-day mortality or readmission. There was 1 access-site complication and 1 cerebrovascular accident within 30 days, both intraoperative, with excellent recovery. All patients had either trivial (19) or mild (4) aortic regurgitation on 30-day echocardiography. CONCLUSIONS TAVR via suprasternal TI access is feasible, safe, provides satisfactory perioperative recovery and adds to the options when patients require alternate access. Further data would be optimal to validate this single-center experience.

Abstract
Symptomatic aneurysms of the innominate and subclavian arteries are rare and pose unique challenges for endovascular repair particularly in a patient with a "bovine" arch. Previous publications have described back table modifications of standard iliac endografts to conform to the innominate artery for exclusion of the lesion. Others have proposed extra-anatomic bypass or carotid-subclavian transposition with occlusion of the innominate artery. We were unable to find a report of repair when aneurysms of the innominate and subclavian arteries were in continuity. We present such a case of endovascular repair using commercially available endografts without compromise of the left common carotid artery origin as this patient had a "bovine" arch. Surgeons will benefit from adding this endovascular option to their "tool box" when confronted with such a challenging clinical scenario.

Abstract
We report a case of a 64-year-old female who first presented with a transient ischemic attack in 2007 due to an innominate artery stenosis, which indicated an endovascular stent placement. In 2008, she presented with recurrence of symptoms and was diagnosed with in-stent restenosis alongside an unusual occurrence of retrograde migration into the ascending aortic arch. We performed an aorto-innominate bypass through a median sternotomy. The patient was discharged without any complications thereafter, and the graft has shown excellent patency. As of 2019, the patient remains well.

Abstract
PURPOSE To analyze aortic arch anatomy of patients who were already treated with a 2-inner-branch arch endograft (2-IBAE) in order to assess the anatomical suitability of the supra-aortic arteries as target vessels for a 3-IBAE. MATERIALS AND METHODS Three different configurations of the Cook Zenith Arch endograft were designed with distances of 110 mm (model 1), 90 mm (model 2), and 70 mm (model 3) between the orifices of the first and third inner branches. Preoperative measurements of the aortic arch anatomy from 104 consecutive patients treated electively with custom-made 2-IBAEs at 2 European centers between 2014 and 2019 were analyzed. A previously described standard methodology with a planning sheet was used. Data and measurements included the treatment indication for the aortic arch pathology, the type of landing zone, the type of arch, and the inner and outer lengths of the ascending aorta from the sinotubular junction to the innominate artery (IA). Additionally, the diameters and clock positions of the IA, left common carotid artery (LCCA), and left subclavian artery (LSA) were assessed, along with the distances between the IA and the LCCA, the IA and the LSA, and the distal landing zone. RESULTS Type I was the most common arch configuration (75/104, 72%). The mean clock positions were 12:30±00:28 for the IA, 12:00±00:23 for the LCCA, and 12:15±00:29 for the LSA. The mean diameters were 14.2±2.2 mm for the IA, 8.8±1.8 mm for the LCCA, and 10.5±2 mm for the LSA. The mean distances between the IA and LCCA and between the IA and LSA were 14.7±5.8 mm and 33±9.4 mm, respectively. Model 2 (branch distance 90 mm) had the highest suitability (79%), while models 1 and 3 showed suitability rates of 73% and 68%, respectively. The most frequent exclusion criterion in all models was the diameter of the LSA, followed by the IA to LSA distance. CONCLUSION The suitability for a 3-IBAE among patients who had a 2-IBAE implanted is high, favoring a 90-mm distance between the retrograde LSA branch and baseline.

Abstract
PURPOSE To evaluate the safety and feasibility of the in situ needle fenestration (ISNF) technique for reconstruction of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) of complicated aortic arch pathologies. MATERIALS AND METHODS A retrospective review was conducted from January 2014 to December 2019 of 50 patients (mean age 60.2±11.1; 45 men) who underwent ISNF to revascularize the LSA during TEVAR. Twenty-one of the patients also required revascularization of the left common carotid artery (LCCA; n=19) and innominate artery (IA; n=2) using physician-modified in vitro fenestration. Overall, 73 supra-aortic branches were targeted for revascularization. RESULTS ISNF was successful in 48 patients (96%); one LSA could not be stented and a tortuous LSA prevented the needle from fenestrating the graft. No perioperative major adverse event occurred. There were no type I and 4 type III endoleaks (8%), 3 of which occurred among the first 20 cases. Types II and IV endoleaks were found in 3 (6%) and 6 (12%) cases, respectively; all disappeared during a median follow-up of 15 months (range 3-66). One death (2%) occurred within 12 months due to cerebral hemorrhage. Two patients (4%) required open reinterventions at 6 and 62 months. CONCLUSION ISNF for revascularization of the LSA during TEVAR seems to be feasible with acceptable midterm outcomes. The learning curve and evolving patient selection criteria affected technical success, complications, and the need for reinterventions. Long-term durability requires further evaluation.

Abstract
Introduction The brachiocephalic artery (BCA) is the largest branch that arises from the aortic arch, which varies in length. The present study focuses on BCA length and its probable correlation with height and torso length. Methods The BCA length (from the artery’s origin to the arcus aortae), the length of the torso, and height were measured in 76 embalmed adult human cadavers of Caucasian (Hellenic) origin. Results A total of 74 arteries were measured (36 females and 38 males). The mean length was found to be 3.82 cm (SD=±0.947, SE=0.110). In male cadavers, the mean BCA length was 3.94 cm (SD=±0.980, SE=0.159) and in females, it was found to be 3.69 cm (SD=±0.905, SE=0.151). No statistically significant difference was found (p=0.248, p>0.05) The mean torso length was 62.27 cm (SD=±4.325, SE=0.496) and the mean height was 155.3 cm (SD=±10.124, SE=1.161). The BCA length was correlated with body height and torso length in both sexes. A statistically significant correlation was found only between BCA length and body height in male cadavers (r=0.267, p=0.021). Conclusion The morphometric characteristics of the BCA are of great importance in a number of surgical procedures, such as stenting and catheterization in cases of aneurysms. One statistically significant correlation was observed in our study, which could be considered an important finding, as it could lead to the plausible assumption that greater height leads to the formation of larger arteries.

Abstract
Tracheo-innominate artery fistula is a rare complication of tracheotomy with very high mortality rate. Only a few patients survive this complication as reported in the literature. Here we report the case of a 54-year-old gentleman who presented to the emergency department with a history of penetrating neck trauma following a road traffic accident. Neck exploration and tracheotomy were done to secure the airway. After two weeks, the patient had an episode of massive stomal bleed for which he was taken to the operating room and re-explored. A tracheo-innominate artery fistula was detected, and right side aorto-carotid and right side aorto-subclavian anastomoses were done using reversed saphenous vein graft with interruption of flow. Following a successful surgery, the patient was decannulated later, and now lives a healthy normal life. Early diagnosis and immediate intervention are the key in managing this complication. Bedside management also plays a vital role.

PURPOSE To describe the implantation steps and tips and tricks for the Inner Branch Arch Endograft designed to treat aortic arch aneurysm and chronic type A aortic dissection. TECHNIQUE Anatomical suitability criteria should be met in order to use this device. The proximal segment of the graft lands in the ascending aorta distally to the sinotubular junction and the distal segment lands in the descending aorta. The device includes 2 inner branches; the proximal branch is used for a connection to the innominate artery (positioned slightly posterior at 12:30 o'clock), while the second branch is positioned slightly anterior at 11:30 o'clock and is used as a connection to the left common carotid artery. Access, implantation technique, deployment of the device, and catheterization of the branches are described thoroughly. CONCLUSION This Inner Branch Arch Endograft is an appealing alternative to treat aortic arch pathology, especially in patients unsuitable for open repair. Nevertheless, complex aortic arch repair is associated with a learning curve. Meticulous preoperative planning and a high level of concentration intraoperatively are mandatory.

A simple method to establish antegrade cerebral perfusion during hemiarch reconstruction. JTCVS Tech 2020; 2:10-15. [PMID: 34317734 PMCID: PMC8298922 DOI: 10.1016/j.xjtc.2020.03.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Revised: 02/09/2020] [Accepted: 03/13/2020] [Indexed: 01/16/2023] Open
Abstract
Objective We describe a novel and safe technique using a 12F-14F pediatric arterial cannula to establish unilateral, selective, antegrade cerebral perfusion (ACP) during open hemiarch reconstruction. Methods Between January 2015 and September 2018, 42 patients underwent elective aortic aneurysm repair requiring an open distal anastomosis and at least a hemiarch replacement via hypothermic circulatory arrest by 2 surgeons. All distal reconstructions were performed at moderate hypothermia (22°C-26°C) with direct cannulation of the innominate artery (IA) using a pediatric arterial cannula to allow ACP at 10-15 mL/kg/min. Data were collected by retrospective chart review. Results Thirty-one of the 42 patients (74%) were male. The mean patient age was 65 ± 13 years, and the mean body surface area was 2.1 ± 0.3 m2. Proximal repairs included a modified Bentall with a valve-graft composite (n = 17), valve-sparing root replacement (n = 2), and aortic valve replacement (n = 15). Perioperative mortality was 2% (n = 1), and the incidence of stroke was 0%. The mean lowest core body temperature reached during circulatory arrest was 23.8 ± 2.7°C with a mean ACP time of 21.8 ± 3.6 minutes. The mean aortic cross-clamp and cardiopulmonary bypass times were 160.6 ± 55.5 minutes and 204.7 ± 57.5 minutes, respectively. There were no cases of IA injury. Conclusions Direct IA cannulation with a pediatric arterial cannula is a safe and efficient method to allow ACP in aortic surgery requiring hypothermic circulatory arrest and may circumvent the potential complications of axillary cannulation.

Abstract
OBJECTIVES Scarring from prior bypass surgery and irradiation may compromise revascularization options in critical ischemia due to underlying occlusive disease. Occlusive disease of the axillo-brachial artery is particularly difficult to revascularize under such hostile conditions. METHOD We present a case of a 58-year-old woman presenting with a painful, pulseless, and cool left upper extremity. The patient had a known history of left upper extremity occlusive disease which was managed by subclavian-axillary artery stenting with re-occlusion and subsequent extra-anatomic left carotid-to-proximal brachial artery prosthetic bypass, which was complicated by stroke. The patient had a history of left mastectomy, axillary node dissection, and external beam radiation therapy. When considering revascularization options, the combination of post-radiation changes and scarring of the conventional operative zones for revascularization posed a high risk for complications. We describe a novel approach for such revascularization, where the inflow source was the terminal brachiocephalic artery, outflow to the upper left brachial artery, with anatomic intrathoracic-to-axillary tunneling through the thoracic outlet after verifying the lack of dynamic extrinsic compression at that level. RESULT The procedure resulted in resolution of the symptoms and the patient continued to do well 2 years later. CONCLUSION This case shows that anatomic tunneling through the thoracic outlet can be a viable option for upper extremity revascularization when hostile conditions preclude other anatomic tunneling routes or extra-anatomic options.

Abstract
Surgery on thoracic aorta is complex with a number of approaches being required depending on the pathology and anatomy that is specific to each patient and therefore, careful planning is required to ensure successful outcomes. Among the key factors that determine a satisfactory and safe operation is the choice of arterial cannulation site to establish cardiopulmonary bypass and deliver brain protection adequately. Direct proximal aortic cannulation is the gold-standard method for elective aortic root surgery and traditionally femoral arterial cannulation has been used in complex aortic surgeries such as redo or acute pathologies; however, axillary and innominate artery (IA) cannulation has evolved dramatically and several centers are currently using proximal cannulation sites as the default cannulation choice in elective and emergency settings of complex thoracic aortic surgeries. The evidence behind cannulating the IA is growing; however, it is yet to be well established through large studies or trial to confirm its superiority to other methods of central cannulation techniques.

Balloon-like Mobile Plaque in the Innominate Artery: Ultrasonographic and Pathological Perspectives of Repetitive Embolism. J Stroke Cerebrovasc Dis 2019; 28:e95-e97.

Abstract
Mobile plaque in the innominate artery is extremely rare and difficult to diagnose, especially in its acute stage. Its diagnosis is often delayed in many cases, resulting in delayed treatment and poor prognosis. Herein, we report the case of a 69-year-old patient with multiple cerebral infarction only in the right internal carotid artery and vertebrobasilar territories. No embolic sources were found until arterial ultrasonography detected a large balloon-like mobile plaque in the IA. Mobile plaque consisted of high-and low-echoic components and showed balloon-like plaque. Despite sufficient antiplatelet therapy, recurrence of cerebral embolism could not be prevented. IA replacement was eventually performed by cardiac surgeons. Pathological examinations showed that organized mobile plaque could have existed previously and acute thrombi, generated after the atheromatous plaque rupture caused by the mechanical burden of organized mobile plaque, could expand along with the organized mobile plaque and caused balloon-like plaque and related with repeated embolism. The IA should be explored immediately in cases of repetitive right-sided cerebral embolisms to prevent further recurrence.

Abstract
OBJECTIVE The innominate artery is considered an alternative site for establishing cardiopulmonary bypass in surgical procedures involving the thoracic aorta. This systematic review examines the use of innominate artery cannulation in aortic surgery. METHODS A systematic literature search was undertaken among the four major databases (PubMed, Embase, Scopus, and Ovid) to identify all studies that utilized innominate artery cannulation for establishing cardiopulmonary bypass and providing cerebral perfusion in thoracic aortic surgery. The data were reviewed up to September 2018. RESULTS Acute type A aortic dissection contributed to 36% (n = 818) of the total 2,290 patients. 31.5% (n = 719) underwent surgery on the aortic root only; 54.5% (n = 1246) had ascending and hemi-arch replacement, while 11.5% had total aortic arch replacement and 2.5% had a frozen elephant trunk inserted. Postoperative stroke rate was 1.25% (n = 28), temporary neurological deficit was 4.8% (n = 111). All-cause 30-day mortality rate was 2.7% (n = 61). CONCLUSION Innominate artery cannulation is a safe technique in patients who undergo thoracic aortic surgery. It can be utilized, in selected cases, as a reliable route for establishing cardiopulmonary bypass and maintaining cerebral perfusion.

Abstract
OBJECTIVE The optimal strategy to deliver antegrade cerebral perfusion for cerebral protection during hypothermic circulatory arrest has not been established. The purpose of this review was to present our current clinical protocol utilizing selective antegrade cerebral perfusion during aortic arch surgery and to compare it to other published experience. CLINICAL PROTOCOL Since 2013, our clinical protocol for aortic arch surgery has evolved to using selective antegrade cerebral perfusion via the innominate artery, moderate hypothermia, and ancillary strategies such as goal-directed perfusion (GDP). Other published techniques favored antegrade cerebral perfusion but were limited by smaller cannulae, multiple cannulation sites, and lower cooling temperatures. CONCLUSION Our clinical protocol may offer higher flow rates, avoid complications associated with additional cannulae, and provide an easy setup for dual arterial perfusion. Additionally, GDP has enhanced our understanding of metabolic physiology and may facilitate the development of a better cerebral protection strategy.

Abstract
PURPOSE To report an uncommon case of chimney stent-graft migration in the aortic arch. CASE REPORT A 29-year-old man presented with chronic left arm hyposthenia after late displacement and thrombosis of a left subclavian artery (LSA) chimney graft that migrated retrogradely into the innominate artery 2 years after deployment. The self-expanding LSA chimney was placed during a redo procedure to repair a pseudoaneurysm and type I endoleak after an index emergency thoracic endovascular aortic repair for traumatic aortic rupture 1 year earlier. The patient was successfully treated in an elective procedure via a median sternotomy, with arch aortotomy under circulatory arrest to remove the proximal end of the thrombosed chimney graft from the ostium of the innominate trunk. Three months later, a left carotid-to-subclavian bypass was performed to restore flow to the left arm. CONCLUSION Migration of the proximal end of an overly long chimney graft that moved freely in the aortic arch exposed the patient to a high risk of stroke and death. Because of the high-risk situation, open repair under circulatory arrest was elected to remove the proximal end of the chimney graft, with no major complications.

Abstract
INTRODUCTION In symptomatic subclavian steal syndrome, endovascular treatment is the first line of therapy prior to extra-anatomic surgical bypass procedures. Subintimal recanalization has been well described in the literature for the coronary arteries, and more recently, in the lower extremities. By modifying this approach, we present a unique retrograde technique using a heavy tip microwire to perform controlled subintimal dissection. METHODS We present two cases of symptomatic subclavian steal related to chronic total occlusion of the left subclavian artery and right innominate artery, respectively. Standard crossing techniques were unsuccessful. Commonly at this point, the procedures would be aborted and open surgical intervention would have to be pursued. In our cases, retrograde access was easily achieved via an ipsilateral retrograde radial artery, using controlled subintimal dissection and a heavy-tipped wire. RESULTS We were able to easily achieve recanalization in both attempted cases of chronic total occlusion of the subclavian and innominate artery, using a retrograde radial subintimal approach. Subsequent stent-supported angioplasty resulted in complete revascularization. No major complications were encountered during the procedures; however, one patient did develop thromboembolic stroke secondary to platelet aggregation to the stent graft, 9 days post-procedure. CONCLUSIONS Endovascular treatment is considered the first-line intervention in medically refractory patients with symptomatic subclavian steal syndrome. In the setting of chronic total occlusions, a retrograde radial subintimal approach using a heavy tip wire for controlled subintimal dissection is a novel technique that may be considered when standard approaches and wires have failed.

Abstract
Blunt traumatic injury to the innominate artery is relatively rare. We present the case of a 40-year-old woman who fell from a fourth-floor window and was transferred to our hospital with multiple injuries, hemodynamic shock, and disturbance of consciousness. Computed tomography with image reconstruction revealed transection of the innominate artery near its origin. Emergent surgery required establishment of cardiopulmonary bypass before sternotomy in preparation for uncontrollable hemorrhage. Proximal aortic arch replacement with a branch to the right axillary artery was successfully performed using circulatory arrest and selective cerebral perfusion.

Abstract
UNLABELLED The management of melioidosis, caused by Burkholderia pseudomallei, presenting as an infected pseudoaneurysm requires radical debridement and prolonged antibiotics because the pathogen is resistant to host immunity. An extra-anatomical bypass might be a better treatment choice than in situ graft interposition or other methods.We report on a 76-year-oldman with an infected pseudoaneurysmlocated in the innominate artery and a method of extra-anatomical bypass that has not yet been reported in the literature. The patient recovered well without recurrence of infection after the surgical procedure. KEY WORDS Burkholderia pseudomallei; Extra-anatomical bypass; Innominate artery; Melioidosis; Pseudoaneurysm.

Abstract
Blunt traumatic injury of the innominate artery occurs infrequently but is commonly lethal. Bovine aortic arch anatomy is a predisposition to this injury. Clinical findings, chest X-ray, and computerized tomography may suggest the diagnosis, and it may be confirmed with angiography. Both interposition and bypass grafting are operative repair methods of choice. EEG monitoring confirms cerebral perfusion, thereby allowing the deferment of shunts and cardiovascular bypass with hypothermic arrest. We report a case of traumatic innominate artery pseudoaneurysm in the setting of "bovine aortic arch" anatomy, together with multiple associated injuries, including descending aorta transection. We also review the current literature on the topic.

Abstract
A 22-year-old woman presented with a history of multiple spells of dizziness, difficulty speaking and occasional loss of consciousness lasting for up to one hour. The patient had been initially diagnosed with epilepsy and treated with Levatiracetam without success. The physical finding of decreased left carotid and radial pulses raised suspicion for Takayasu arteriitis and the patient was referred to our center for further evaluation including cerebral angiography. Angiography was performed via two 5-French sheaths placed in the right femoral and left radial arteries. The patient was found to have only two great vessels originating from the aortic arch, while the left carotid and subclavian arteries shared a common origin and did not communicate with the arch. There was prominent subclavian steal through the vertebrobasilar junction and through hyper-trophied spinal arteries. The right internal carotid artery supplied the left hemisphere through the anterior communicating artery and also provided flow to the posterior cerebral arteries. No vascular lesions were identified to support the diagnosis of vasculitis. Atresia of a left innominate artery is an extremely rare aortic arch variant1, 2 which, as in this case can lead to symptomatic subclavian steal. Surgical options are being discussed with the patient1.
