Abstract
PURPOSE To investigate the morphological characteristics and operative outcomes of acute type A aortic dissection (ATAAD) in patients with aortic arch variants. METHODS Of 616 patients with ATAAD, 97 (15.7%) had aortic arch variants, including bovine aortic arch (BAA, n = 66), isolated left vertebral artery (ILVA, n = 25), and aberrant subclavian artery (ASA, n = 6). The characteristics and outcomes were compared between the normal branching group (control, n = 519) and the total/individual arch variant groups. RESULTS Compared to the control group, arch entry was more prevalent in the BAA (18.5% vs. 31.8%) and ILVA groups (44%) (both, P < 0.05), and right common carotid arterial occlusion was less common in the arch variant group (6.7% vs. 0%, P = 0.017). The in-hospital mortality (9.2% vs. 9.3%), new-onset stroke (7.3% vs. 7.2%), and 5-year survival (81.7% vs. 78.8%) did not differ markedly between the control and arch variant groups. Arch repair was performed in 28.9% (28/97) of the arch variant group using 3-4 vessel antegrade cerebral perfusion, with 3.8% in-hospital mortality and a 15.4% stroke rate, which were comparable to those of the control group. CONCLUSIONS Aortic arch variants may influence tear location and involvement of the supra-arch vessels but may not affect postoperative outcomes.

J Vasc Surg 2024; 79:991-996. [PMID: 38262566 DOI: 10.1016/j.jvs.2024.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 01/04/2024] [Accepted: 01/17/2024] [Indexed: 01/25/2024]
Abstract
OBJECTIVE Left vertebral artery revascularization is indicated in surgery involving zone 2 of the aortic arch and is typically accomplished indirectly via subclavian artery revascularization. For aberrant left vertebral anatomy, direct revascularization is indicated. Our objective was to compare the outcomes of direct vertebral artery revascularization with indirect subclavian artery revascularization for treating aortic arch pathology and to identify predictors of mortality. METHODS A retrospective cohort study was conducted at a single tertiary hospital, including patients who underwent open or endovascular vertebral artery revascularization from 2005 to 2022. Those who underwent direct vertebral revascularization were compared with those who were indirectly revascularized via subclavian artery revascularization. The outcomes of interest were a composite outcome (any of death, stroke, nerve injury, and thrombosis) and mortality. Univariate logistic regression models were fitted to quantify the strength of differences between the direct and indirect revascularization cohorts. Cox regression was used to identify mortality predictors. RESULTS Of 143 patients who underwent vertebral artery revascularization, 21 (14.7%) had a vertebral artery originating from the aortic arch. The median length of stay was 10 days (interquartile range, 6-20 days), and demographics were similar between cohorts. The incidence of composite outcome, bypass thrombosis, and hoarseness was significantly higher in the direct group (42.9% vs 18.0%, P = .019; 33.3% vs 0.8%, P < .0001; 57.1% vs 18.0%, P < .001, respectively). The direct group was approximately three times more likely to experience the composite outcome (odds ratio, 3.41; 95% confidence interval, 1.28, 9.08); similarly, this group was approximately six times more likely to have hoarseness (odds ratio, 5.88; 95% confidence interval, 2.21, 15.62). There was no significant difference in mortality rates at 30 days, 1, 3, 5, and 10 years of follow-up. Age, length of hospital stay, and congestive heart failure were identified as predictors of higher mortality. After adjusting for these covariates, the group itself was not an independent predictor of mortality. CONCLUSIONS Direct vertebral revascularization was associated with higher rates of composite outcome (death, stroke, nerve injury, and thrombosis), bypass thrombosis and hoarseness. Patients with aberrant vertebral anatomy are at higher risks of these complications compared with patients with standard arch anatomy. However, after adjusting for other factors, mortality rates were not significantly different between the groups.

Abstract
Objective The main purpose of this study was to evaluate the safety and efficacy of Castor single-branched stent-graft combined with fenestrated technique in treatment of thoracic aortic disease (TAD) with unfavorable proximal landing area (PLZ) and isolated left vertebral artery (ILVA). Methods From January 2018 to March 2022, 8 patients with TAD (6 patients with type B aortic dissections, 1 patient with type B intramural hematomas, and 1 patient with thoracic aortic aneurysm) underwent thoracic endovascular aortic repair with fenestrated Castor stent-graft due to the existence of ILVA and unfavorable PLZ. Demographic characteristics, surgical details, postoperative complications, follow-up and postoperative CTA imaging results were collected and analyzed. Results The primary technical success rate was 100%. The mean operation time was 115 min (range, 70-180 min). All the left subclavian arteries (LSAs) and ILVAs of the eight patients were revascularized by fenestrated Castor stent-grafts. During the follow-up period, no deaths and complications were observed. No internal leakage, aortic rupture, retrograde type A dissection were found on computed tomography angiography. All of the LSAs and ILVAs maintained patency without stenosis. Conclusion Castor single-branched stent-graft implantation combined with fenestration technique may be safe and feasible for TAD patients with ILVA and unfavorable PLZ.

Abstract
Objective To present our experience of preserving the isolated left vertebral artery (ILVA) with physician-modified fenestration (PM-F) or in situ fenestration (ISF) during thoracic endovascular aortic repair (TEVAR) for aortic pathologies involving aortic arch. Methods This is a single-center, retrospective, observational cohort study. Between June 2016 and December 2021, 9 patients (8 men; median age 60.0 years old) underwent TEVAR with ILVA reconstruction (PM-F, n = 6; ISF, n = 3) were identified and analyzed. Results The technical success rate was 100%. No early (<30 days) death occurred. No aortic rupture, major stroke or spinal cord injury was observed. The median follow up was 38.0 (rang: 1.0-66.0) months. One death occurred at 56 months, while the reason cannot be identified. No aortic rupture, major stroke or spinal cord injury was observed during follow up. No patient required reintervention. Out of the 22 successfully revascularized target vessels, 2 ILVAs were found occluded in 2 patients at 6 months and 7 months, respectively. However, these two patients were asymptomatic. Conclusions Our initial experience reveals that PM-F or ISF for ILVA preservation was feasible, safe, and effective during TEVAR for complex thoracic aortic pathologies. However, the patency of preserved ILVA should be improved.

Surgical treatment strategies for patients with type A aortic dissection involving arch anomalies. Front Cardiovasc Med 2022; 9:979431.

Abstract
Objective The aim of the study was to investigate surgical modalities and outcomes in patients with type A aortic dissection involving arch anomalies. Method Patients with type A aortic dissection who underwent surgical treatment at our center between January 2017 and 31 December 2020 were selected for this retrospective analysis. Data including computed tomography (CT), surgical records, and cardiopulmonary bypass records were analyzed. Perioperatively survived patients were followed up, and long-term mortality and aortic re-interventions were recorded. Result A total of 81 patients with arch anomalies were included, 35 with “bovine” anomalies, 23 with an aberrant right subclavian artery, 22 with an isolated left vertebral artery, and one with a right-sided arch + aberrant left subclavian artery. The strategies of arch management and cannulation differed according to the anatomic variation of the aortic arch. In total, seven patients (9%) died after surgery. Patients with “bovine” anomalies had a higher perioperative mortality rate (14%) and incidence of neurological complications (16%). Overall, four patients died during the follow-up period, with a 6-year survival rate of 94.6% (70/74). A total of four patients underwent aortic re-intervention during the follow-up period; before the re-intervention, three received the en bloc technique (13.6% 3/22) and one received hybrid therapy (11.1% 1/9). Conclusion With complete preservation and reconstruction of the supra-arch vessels, patients with type A aortic dissection combining arch anomalies can achieve a favorable perioperative prognostic outcome. Patients who received the en bloc technique are more likely to require aortic re-intervention than patients who underwent total arch replacement with a four-branched graft vessel. Cannulation strategies should be tailored according to the variation of anatomy, but routine cannulation with the right axillary artery can still be performed in most patients with arch anomalies, even for patients with an aberrant right subclavian artery.

Abstract
Objectives: The aim of this study was to present our experience with the management of isolated left vertebral artery (ILVA) during complex thoracic aortic pathology treated with the hybrid thoracic endovascular aortic repair. Methods: This is a single-center, respective cohort study. Between June 2016 and June 2020, 13 patients (12 men; median age 60 years old, range 42–72 years old) who underwent hybrid procedures were identified with ILVA in our center. Demographics, imaging features, operation details, and follow-up in these patients were collected and analyzed. Results: In this study, all patients received the hybrid procedure, and the primary technical success rate was 100%. There were no in-hospital deaths. Complication occurred in two (15.4%) patients. One patient suffered from contrast-induced acute kidney injury (CI-AKI) and recovered before discharge. Another patient required reintervention for acute left-lower-limb ischemia, which was successfully treated using Fogarty catheter embolectomy. Immediate vagus/recurrent laryngeal never palsy, lymphocele, and chylothorax were not observed. The median duration of follow-up was 22 months (range, 13–29 months). No neurologic deficits, bypass occlusion, or ILVA occlusion or stenosis were observed during the follow-up. No aortic rupture, cerebrovascular accident, or spinal cord ischemia was observed during the follow-up period. Conclusions: Our limited experience reveals that hybrid procedures [thoracic endovascular aortic repair (TEVAR), ILVA transposition, and left common carotid artery-left subclavian artery (LCCA-LSA) bypass] are relatively safe, feasible, and durable for the treatment of thoracic aortic pathology with ILVA. However, further technique durability and larger studies with long-term follow-up periods are warranted.

Abstract
This review highlights vital details that can be easily overlooked and discuss how to identify and fix failed cannulation from another novel insight. Appropriate arterial cannulation strategy during cardiopulmonary bypass (CPB) in Stanford type A aortic dissection (AAD) is highly necessary to reach satisfactory perfusion effects and appreciable clinical outcomes. Despite several previously published reviews on cannulation strategies in AAD, most focus on the advantages and disadvantages by comparing various cannulation strategies. In fact, most of evidence came from retrospective studies. More importantly, however, some important details and novel approaches maybe overlooked due to variety reasons. These overlooked details also make sense in clinical practice. Papers related to cannulation refer to type AAD were retrieved and analyzed from the PubMed and Medline database. The key words such as “aortic dissection”, “cannula”, “cannulation”, “cannulation strategy”, “cerebral perfusion”, “type I aortic dissection” were conducted and analyzed. In addition, we looked at some new and very significant specific perfusion techniques such as anterograde cerebral perfusion combined with retrograde inferior vena caval perfusion (RIVP) and reperfusion via the right carotid artery before surgery. The arterial cannulation site and strategy should be determined individually. Monitoring measures are very necessary in the whole procedure.

Abstract
A 47-year-old male presented with an enlarging distal aortic arch false lumen 6 months status post ascending and hemiarch replacement with antegrade endograft insertion for acute type A aortic dissection complicated by lower body malperfusion. Preoperative computed tomographic angiography showed an isolated but dominant left vertebral artery. A 2-stage open surgical repair was performed. First, the left subclavian artery was transposed on the common carotid and vertebral onto the subclavian. At the second stage, a redo total arch reconstruction was done with bypass grafts taken to the innominate and left common carotid arteries. The patient did well postoperatively.

Abstract
OBJECTIVES The aim of this study was to present our experience with the management of isolated left vertebral artery during hybrid aortic arch repairs with thoracic endovascular aortic repair completion. METHODS This is a single-center, observational, cohort study. Between January 2007 and December 2018, 9 patients (4.5%) of 200 who underwent thoracic endovascular aortic repair were identified with isolated left vertebral artery. The isolated left vertebral artery was the dominant vertebral artery in 4 cases and entered the Circle of Willis to form the basilar artery in all cases. Isolated left vertebral artery transposition was performed in 2 patients during open ascending/arch repair before thoracic endovascular aortic repair completion. In 4 patients, isolated left vertebral artery transposition was performed concomitant with carotid-subclavian bypass during thoracic endovascular aortic repair completion ("zone 2" thoracic endovascular aortic repair). Primary outcomes were early (<30 days) and late survival, freedom from aortic-related mortality, and isolated left vertebral artery patency. RESULTS Primary technical success was achieved in all cases. Isolated left vertebral artery-related complication occurred in 1 patient (Horner syndrome). Immediate thrombosis, vagus/recurrent laryngeal nerve palsy, lymphocele, and chylothorax were never observed. Postoperative cerebrovascular accident or spinal cord injury was not observed. Median follow-up was 15 months (range, 3-72). We did not observe aortic-related mortality during the follow-up. Aortic-related intervention was never required. Both isolated left vertebral artery and carotid-subclavian bypass are still patent in all patients with no sign of anastomotic pseudoaneurysm or stenosis. CONCLUSIONS Although isolated left vertebral artery is not a frequent occurrence, it is not so rare. It may pose additional difficulties during hybrid aortic arch surgical repairs, but isolated left vertebral artery transposition was feasible, safe, and a durable reconstruction.

Abstract
OBJECTIVE The objective of this study was to report our single-center experience of thoracic endovascular aortic repair (TEVAR) and concomitant procedures in patients with type B aortic dissection (TBAD) with an isolated left vertebral artery (ILVA) and the early to midterm outcomes in these patients. METHODS Between March 2011 and June 2018, there were 31 patients (27 men; median age, 55 years; range, 31-66 years) with TBAD and an ILVA who received TEVAR and concomitant procedures in our center. Demographics, coexisting medical conditions, imaging features, operation details, and follow-up outcomes in these patients were retrospectively collected and analyzed. RESULTS All patients received aortic stent grafts; nine patients also received chimney stents, and 10 patients received aortic arch bypasses. The technical success rate was 96.8% (30/31), with only one patient (3.2%) showing immediate type IA endoleak. One patient experienced transient neurologic deficit, and a puncture-related femoral artery pseudoaneurysm was observed in one patient; both recovered completely before their hospital discharge. There was no death in the early term. The median duration of follow-up was 33 months (range, 2-90 months). Reintervention for a type II endoleak by using coils to seal the origin of the left subclavian artery was performed in one (3.1%) case 72 months postoperatively. One (3.2%) death occurred 42 months after operation as a result of rectal cancer. No neurologic deficits, chimney stent occlusions, or bypass occlusions were observed during the follow-up period. CONCLUSIONS Our limited experience reveals that TEVAR and concomitant procedures are relatively safe and viable for treatment of TBAD with an ILVA. Further studies with larger samples of patients and longer follow-ups are needed to confirm these findings.

Abstract
BACKGROUND Acute type B dissection with ascending thoracic aortic dilatation (ATAD) is very common, but remains surgically challenging with the use of the conventional single-stage procedure via median sternotomy or lateral thoracotomy. We report our experience with repair of acute type B dissection with ATAD using a one-stage stented elephant trunk procedure. METHODS We retrospectively reviewed the medical records of 16 patients (13 males and 3 females) with acute type B dissection with ATAD who underwent ascending thoracic aortic reconstruction combined with a stented elephant trunk procedure under hypothermic cardiopulmonary bypass with selective antegrade cerebral perfusion between February 2009 and February 2013. ATAD included ascending aortic aneurysm in four patients, ascending aortic enlargement + aortic regurgitation in three, and ascending aortic aneurysm + aortic root aneurysm in nine. Lower limb ischemia occurred in one case. RESULTS There was no in-hospital mortality. Drainage of the pericardial sac was indicated for two patients with pericardial effusion. The median durations of ventilator support and intensive care unit stay were 25 ± 18 and 48 ± 7 hours, respectively. Lower limber ischemia was alleviated after implantation of a stented elephant trunk. One patient received thoracoabdominal aortic replacement during follow-up and encountered no postoperative complications. CONCLUSIONS Satisfactory surgical results and follow-up outcomes can be achieved using the proposed one-stage stented elephant trunk procedure for acute type B dissection with ATAD.

Abstract
OBJECTIVES The presence of an isolated left vertebral artery (ILVA) remains a challenging issue for thoracic endovascular aortic repair (TEVAR) of type B dissection if the proximal landing zones are inadequate. We retrospectively reviewed our experience of the surgical management of complicated type B dissection with an ILVA using the stented elephant trunk technique. METHODS Between February 2009 and May 2013, 7 patients with complicated type B dissection (acute = 2 and chronic = 5) underwent the stented elephant trunk procedure under hypothermic cardiopulmonary bypass with selective antegrade cerebral perfusion. All the patients were males with a median age of 53 ± 6 (range 42-59) years. Preoperative lower limb ischaemia was observed in 1 patient, renal dysfunction in 1 patient and visceral ischaemia in 1 patient. RESULTS There were no in-hospital deaths. The median ventilator support time was 16 ± 3 (range 11-20) h. Ischaemia of the lower limb and viscera was ameliorated after surgical stent-graft implantation. Continuous renal replacement therapy was not required in patients with preoperative renal dysfunction after surgery. No neurological deficits were observed in any patients prior to hospital discharge. One patient underwent TEVAR due to distal aortic dilatation within the mean follow-up period, which was 44 ± 19 months. CONCLUSION Repair of complicated type B dissection with an ILVA using the stented elephant trunk technique was associated with satisfactory surgical results in patients with inadequate proximal fixation zones. This technique is an alternative to TEVAR for complicated type B dissection with inadequate proximal landing zones.
