Kim M, Han JH, Kim DH, Yoon M, Jung HJ. Simultaneous Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm Combined with Saccular Thoracic Aortic Aneurysm. Vasc Specialist Int 2023; 39:29. [PMID: 37748931 PMCID: PMC10519935 DOI: 10.5758/vsi.230075] [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: 07/31/2023] [Revised: 08/21/2023] [Accepted: 08/28/2023] [Indexed: 09/27/2023] Open
Abstract
With the recent increase in imaging tests, coexisting abdominal aortic aneurysms (AAAs) and thoracic aortic aneurysms (TAAs) are being discovered accidentally. We report two cases of simultaneous endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) for AAA and TAA. Both 74-year-old and 79-year-old male with infrarenal AAA and saccular TAA were treated simultaneously with EVAR and TEVAR. Saccular TAAs were identified in the upper thoracic aorta during the evaluation of AAA. During endograft placement, carotid-subclavian bypass and cerebrospinal fluid (CSF) drainage were performed. Both patients were successfully discharged without spinal cord ischemia. Simultaneous EVAR and TEVAR can be considered for patients with AAA and saccular TAA in the upper thoracic aorta. Moreover, CSF drainage may be necessary to protect the spinal cord.

Five-year sex-related outcomes of thoracic endovascular aortic repair in the Global Registry for Endovascular Aortic Treatment. J Vasc Surg 2023; 78:604-613.e4. [PMID: 37224892 DOI: 10.1016/j.jvs.2023.05.027] [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: 03/03/2023] [Revised: 05/10/2023] [Accepted: 05/15/2023] [Indexed: 05/26/2023]
Abstract
OBJECTIVE The impact of sex on outcomes of thoracic endovascular aortic repair (TEVAR) represents an area of increased interest over the last decade, and long-term data are lacking. The aim of the present study was to investigate sex-related differences in long-term outcomes after TEVAR using real-world data from the Global Registry for Endovascular Aortic Treatment. METHODS Data were obtained retrospectively after querying the multicenter, sponsored Global Registry for Endovascular Aortic Treatment. Patients treated with TEVAR between December 2010 and January 2021 were selected regardless of the type of thoracic aortic disease. The primary outcome was sex-specific all-cause mortality at 5 years and maximum follow-up. Secondary outcomes were sex-specific all-cause mortality at 30 days and 1 year, and aorta-related mortality, major adverse cardiac events, neurological complications, and device-related complications or reinterventions at 30 days, 1 year, 5 years, and maximum follow-up. RESULTS A total of 805 patients were analyzed; 535 (66.5%) were males. Females were older (median, 66 years [interquartile range (IQR), 57-75 years] vs 69 years [IQR, 59-78 years], P < .001). Males had more frequently a history of coronary artery bypass grafting and renal insufficiency (8.7% vs 3.7% [P = .010] and 22.4% vs 11.6% [P < .001]). The median follow-up was 3.46 years (IQR, 1.49-4.99 years) for males and 3.18 years (IQR, 1.29-4.86 years) for females. Indications for TEVAR were mostly descending thoracic aortic aneurysms (n = 307 [38.1%]) type B aortic dissections (n = 250 [31.1%]) or others (n = 248 [30.8%]). Freedom from 5-year all-cause mortality was similar for males and females (67% [95% CI, 62.1-72.2] vs 65.9% [95% CI, 58.5-74.2]; P = .847), and there were no differences in secondary outcomes. Multivariable Cox regression showed females to have lower all-cause mortality rates; however, this difference did not reach statistical significance (hazard ratio, 0.97; 95% CI, 0.72-1.30; P = .834). Additional subgroup analyses based on the indication for TEVAR did not identify differences between both sexes for the primary and secondary outcomes except more endoleak type II in females with complicated type B aortic dissection (1.8% vs 12.1%; P = .023). CONCLUSIONS The present analysis suggests that long-term outcomes of TEVAR performed irrespective of the type of aortic disease are similar for males and females. Further studies are needed to clarify existing controversies regarding the impact of sex on outcomes of TEVAR.

Abstract
This case report describes a case of severe dysphagia lusoria secondary to an aberrant right subclavian artery causing compression of the esophagus. Our 62-year-old female patient presented with severe dysphagia and underwent right carotid-subclavian bypass with uncovered thoracic endovascular aortic repair and coil embolization of the aberrant right subclavian artery. This case is unique in that an uncovered dissection stent graft was used to avoid occluding the anatomic left subclavian artery and, therefore, avoid a left carotid-subclavian bypass. This case highlights a unique anatomic variant, its surgical repair, and the long-term improvement in the patient's quality of life.

Abstract
This study aimed to modify a laser Doppler flowmeter designed and assembled at our institute. After measuring sensitivity evaluation in ex vivo experiments, we confirmed the efficacy of this new device for monitoring real-time esophageal mucosal blood flow changes after thoracic stent graft implantation by simulating various clinical situations in an animal model. Thoracic stent graft implantation was performed in a swine model (n = 8). Esophageal mucosal blood flow decreased significantly from baseline (34.1 ± 18.8 ml/min/100 g vs. 16.7 ± 6.6 ml/min/100 g, P < 0.05) in the lower esophagus (Th6-Th8) where the stent graft covered the aorta. In the hemorrhagic shock model (shock index ≥ 1.0), esophageal mucosal blood flow showed a remarkable change from baseline in the upper esophagus (Th1-Th3), where the stent graft did not cover the aorta (20.8 ± 9.8 ml/min/100 g vs. 12.9 ± 8.6 ml/min/100 g, P < 0.01); however, it returned to the baseline value within a 30-min period. Mucosal blood flow remained stable in the esophagus, where the stent graft did not cover the aorta. After elevating the mean blood pressure to > 70 mmHg with continuous intravenous noradrenaline infusion, esophageal mucosal blood flow increased significantly in both regions; however, the reaction was different between the two regions. Our newly developed laser Doppler flowmeter could measure real-time esophageal mucosal blood flow changes in various clinical situations during thoracic stent graft implantation in a swine model. Hence, this device can be applied in many medical fields by downsizing it.

[PMID: 36889606 DOI: 10.1016/j.jvs.2023.02.014] [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: 11/29/2022] [Revised: 02/21/2023] [Accepted: 02/21/2023] [Indexed: 03/08/2023]
Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) has emerged as a viable option of treatment for uncomplicated type B aortic dissection (UTBAD) due to the potential for inducing favorable aortic remodeling. The aim of this study is to compare outcomes of UTBAD treated medically or with TEVAR in either the acute (1 to 14 days) or subacute period (2 weeks to 3 months). METHODS Patients with UTBAD between 2007 and 2019 were identified using the TriNetX Network. The cohort was stratified by treatment type (medical management; TEVAR during the acute period; TEVAR during the subacute period). Outcomes including mortality, endovascular reintervention, and rupture were analyzed after propensity matching. RESULTS Among 20,376 patients with UTBAD, 18,840 were medically managed (92.5%), 1099 patients were in the acute TEVAR group (5.4%), and 437 patients were in the subacute TEVAR group (2.1%). The acute TEVAR group had higher rates of 30-day and 3-year rupture (4.1% vs 1.5%; P < .001; 9.9% vs 3.6%; P < .001) and 3-year endovascular reintervention (7.6% vs 1.6%; P < .001), similar 30-day mortality (4.4% vs 2.9%; P < .068), and lower 3-year survival compared with medical management (86.6% vs 83.3%; P = .041). The subacute TEVAR group had similar rates of 30-day mortality (2.3% vs 2.3%; P = 1), 3-year survival (87.0% vs 88.8%; P = .377) and 30-day and 3-year rupture (2.3% vs 2.3%; P = 1; 4.6% vs 3.4%; P = .388), with significantly higher rates of 3-year endovascular reintervention (12.6% vs 7.8%; P = .019) compared with medical management. The acute TEVAR group had similar rates of 30-day mortality (4.2% vs 2.5%; P = .171), rupture (3.0% vs 2.5%; P = .666), significantly higher rates of 3-year rupture (8.7% vs 3.5%; P = .002), and similar rates of 3-year endovascular reintervention (12.6% vs 10.6%; P = .380) compared with the subacute TEVAR group. There was significantly higher 3-year survival (88.5% vs 84.0%; P = .039) in the subacute TEVAR group compared with the acute TEVAR group. CONCLUSIONS Our results found lower 3-year survival in the acute TEVAR group compared with the medical management group. There was no 3-year survival benefit found in patients with UTBAD who underwent subacute TEVAR compared with medical management. This suggests the need for further studies looking at the necessity for TEVAR when compared with medical management for UTBAD as it is non-inferior to medical management. Higher rates of 3-year survival and lower rates of 3-year rupture in the subacute TEVAR group compared with the acute TEVAR group suggest superiority of subacute TEVAR. Further investigations are needed to determine the long-term benefit and optimal timing of TEVAR for acute UTBAD.

Abstract
OBJECTIVE To evaluate early and midterm outcomes of the Candy Plug (CP) technique for distal false lumen (FL) occlusion in thoracic endovascular aortic repair for aortic dissection (AD) in a more real world cohort of patients from an international multicentre registry. METHODS A multicentre retrospective study was conducted of all consecutive patients from the contributing centres with subacute and chronic AD treated with the CP technique from October 2013 to April 2020 at 18 centres. RESULTS A custom made CP was used in 155 patients (92 males, mean age 62 ± 11 years). Fourteen (9%) presented with ruptured false lumen aneurysms. Technical success was achieved in all patients (100%). Clinical success was achieved in 138 patients (89%). The median hospital stay was 7 days (1 - 77). The 30 day mortality rate was 3% (n = 5). Stroke occurred in four patients (3%). Spinal cord ischaemia occurred in three patients (2%). The 30 day computed tomography angiogram (CTA) confirmed successful CP placement at the intended level in all patients. Early complete FL occlusion was achieved in 120 patients (77%). Early (30 day) CP related re-intervention was required in four patients (3%). The early (30 day) stent graft related re-intervention rate was 8% (n = 12). Follow up CTA was available in 142 patients (92%), with a median follow up of 23 months (6 - 87). Aneurysmal regression was achieved in 68 of 142 patients (47%); the aneurysm diameter remained stable in 69 of 142 patients (49%) and increased in five of 142 patients (4%). A higher rate of early FL occlusion was detected in the largest volume centre patients (50 [88%] vs. 70 [71%] from other centres; p = .019). No other differences in outcome were identified regarding volume of cases or learning curve. CONCLUSION This international CP technique experience confirmed its feasibility and low mortality and morbidity rates. Aortic remodelling and false lumen thrombosis rates were high and support the concept of distal FL occlusion in AD using the CP technique.

Abstract
OBJECTIVE The aim of this study was to evaluate safety and efficacy of thoracic endovascular aortic repair (TEVAR) for acute Stanford type B aortic dissection (TBAD) with retrograde type A intramural hematoma (TAIMH). METHODS Patients with acute TBAD with retrograde TAIMH treated with TEVAR between January 1, 2014, to March 31, 2022, were retrospectively reviewed. Aortic diameter and distance were measured using the 3D Slicer image computing platform. Patients' characteristics, procedural, in-hospital and follow-up data, and aortic remodeling were analyzed. RESULTS Fifty-two patients (average age, 52.6 years; 42 males [80.8%]) were included. The median interval from symptom onset to TEVAR was 11 days (interquartile range, 7.0-16.8 days). The maximal diameter of the ascending aorta (AA) was <50 mm, and the hematoma thickness in the AA was ≤10 mm in all patients. Both the in-hospital and 30-day mortality rates were 0%. The 30-day complication rate was 11.5%. The overall cumulative survival rates were 100% at 1 year, 97.1% at 3 years, and 92.6% at 5 years. Four of 52 patients (7.7%) developed retrograde type A aortic dissection at 10 days to 4 months postoperatively, and one of 52 patients (1.9%) developed an isolated AA dissection 4 months postoperatively; these five patients were treated and alive at late follow-up in March 2022. The rates of cumulative freedom from thoracic aortic re-intervention were 93.7% at 1 year and 90.7% at 5 years. Positive AA remodeling was observed in 92.3% (48/52) of patients during follow-up. The maximal diameter of AA (mean ± standard error of mean) at admission was 42.7 ± 0.8 mm, which decreased to 39.5 ± 0.9 mm at last follow-up. The maximal AA hematoma thickness at admission was 7.6 ± 0.3 mm, which reduced to 2.2 ± 0.9 mm at last follow-up. CONCLUSIONS For selected patients of acute Stanford TBAD with retrograde TAIMH, endovascular repair may be a safe, effective, and durable alternative treatment, if the maximum diameter of the AA is <50 mm and the intramural hematoma thickness in the AA is ≤10 mm.

Abstract
Background Although commonly used for the treatment of descending aortic dissection, endovascular repair is challenging for ascending aortic pseudoaneurysms. Rapid ventricular pacing (RVP), a method that temporarily impedes cardiac output by stopping ventricular activity, heralds potential benefits for thoracic endovascular aortic repair (TEVAR) during precision landing. Recently, we successfully treated an anastomosis pseudoaneurysm after the Bentall procedure using TEVAR assisted by RVP. Case report A 69-year-old male was admitted to our hospital with a ascending aortic anastomosis pseudoaneurysm. He had undergone a Bentall procedure and a coronary artery bypass grafting nine years prior. After extensive consultation, the decision was made to perform TEVAR with the assistance of RVP. After a covered stent graft was delivered to the precise location of the ascending aorta, RVP was performed at a frequency of 180 beats/min with a pacemaker. When a flattened arterial blood wave of <50 mmHg was observed, the stent graft was released precisely between the opening of the coronary graft and innominate artery. Angiography revealed the presence of an endoleak; therefore, a set of interlock coils were packed into the aneurysm. Subsequent angiography showed intact blood flow in the aorta, superior arch branches, and coronary graft vessels. The patient recovered uneventfully after the procedure. He was discharged six days later and was doing well at the eight-month follow-up. Conclusion The case indicates that TEVAR assisted by RVP is a promising combination for ascending aortic pseudoaneurysm in selected patients.

Abstract
Objective To investigate the factors influencing distal false lumen enlargement after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection. Materials and methods Data were collected on patients with type B aortic dissection who underwent TEVAR from January 2008 to August 2022. Patients were divided into a distal aortic segmental enlargement (DSAE) group and a non-DSAE group based on whether the distal false lumen was dilated more than 5 mm on computed tomographic angiography (CTA) images. To analyze the independent influences on distal false lumen dilatation after TEVAR, the variables with a P value < 0.05 during univariate analysis were included in the binary logistic regression analysis model. Results A total of 335 patients were included in this study, with 85 in the DSAE group and 250 in the non-DSAE group. The mean age was 52.40 ± 11.34 years, 289 (86.27%) were male patients, and the median follow-up time was 6.41 (11.99-29.99) months. There were significant differences in Marfan syndrome, chronic obstructive pulmonary disease (COPD), and follow-up time between the two groups. In terms of morphology, there were statistically significant differences in the number of tears, the size of the primary tear, and the length of dissection between the two groups. Binary logistic regression analysis indicated that Marfan syndrome, COPD, and the primary tear size were associated with distal false lumen dilatation. Conclusions Marfan syndrome, COPD, and the primary tear size influence distal aortic segmental enlargement after TEVAR in type B aortic dissection patients.

Abstract
PURPOSE To report the early 2-year results and experience of a novel gutter-plugging chimney stent-graft in a single center that participated in the clinical trial of Prospective Study for Aortic Arch Therapy with stENt-graft for Chimney technology. MATERIALS AND METHODS Patients diagnosed with aortic dissection were treated with the novel chimney stent-grafts named Longuette™ for the left subclavian artery revascularization. Primary study outcomes were the incidence of freedom from major adverse events within 30 days and success rate of the operation over 12 months. RESULTS A total of 34 patients were enrolled between September 2019 and December 2020. The immediate technical success rate (stent-grafts successfully deployed without fast-flow type Ia or type III endoleak intraoperatively) was 100%, and there were no conversions to open repair. Type Ia and type II endoleaks were noted in three patients (8.8%) and one patient (2.9%) at discharge, respectively. One patient (2.9%) with type Ia endoleak underwent coil embolization at 12 months because of false lumen dilation, and one (2.9%) case of type Ia endoleak resolved spontaneously at 24 months. One chimney stent (2.9%) was revealed with stenosis at discharge and occluded with thrombosis at 6 months postoperatively. During the 2-year follow-up, there was no death, rupture, stroke, paraplegia, left arm ischemia, retrograde dissection, stent-graft induced new entry, or stent migration. CONCLUSION The initial results of the Longuette™ stent-graft for revascularization of the left subclavian artery are encouraging with a high technical success rate. Further multicenter follow-up outcomes are required to assess the long-term durability. LEVEL OF EVIDENCE Level 4, Case Series.

Abstract
BACKGROUNDS Survival and aortic-related adverse events after thoracic endovascular aortic repair (TEVAR) for aortic intramural hematoma (IMH) and aortic dissection (AD) are controversial. We aimed to assess the preoperative characteristics and to evaluate TEVAR outcomes of acute type B IMH and AD. METHODS Between June 2002 and May 2021, 83 patients with acute type B IMH and 755 patients with acute type B AD underwent TEVAR at the General Hospital of Northern Theater Command. We retrospectively analyzed data from these patients, including clinical characteristics and follow-up outcomes. RESULTS The patients with IMH were significantly older than the ones with AD (P < 0.001). Diabetes mellitus (P = 0.035) and ischemic cerebrovascular disease (P = 0.017) were more common in the IMH group than in the AD group. The results demonstrated a less long-term aortic-related death-free survival rate in the IMH group than the AD group for all the patients (P = 0.014) and the matched patients (P = 0.027). It also presents a lower long-term overall survival rate (P = 0.047) and aortic-related event-free rate (P = 0.048) in the IMH group than in the matched patients. CONCLUSIONS Compared with AD patients, patients with IMH who underwent TEVAR had a worse long-term outcome of aortic-related survival in all and matched patients.

METHODS The early and mid-term outcomes were analyzed for 413 patients undergoing TEVAR using conformable TAG thoracic endoprosthesis and Valiant Captivia thoracic stent graft for acute TBAD. 100 propensity-matched pairs of patients were generated, including 100 patients in the CTAG group and 200 patients in the Valiant Captivia group. RESULTS Operative mortality were 2.33% (3 of 129) in the CTAG group and 1.76% (5 of 284) in the Valiant Captivia group. The median follow-up was 41.67 (26.00-60.67) months. No significant difference in mortality (9 [7.00%] vs. 36 [12.68%], P = 0.95) or re-intervention rate (3 [2.33%] vs. 20 [7.04%], P = 0.29) was observed between two groups. CTAG group have a lower incidence rate of distal stent graft-induced new entry tear than Valiant Captivia group (2.33% vs. 9.86%, P = 0.045). Lower incidence of type Ia endoleak was identified in the CTAG group (2.22%) than the Valiant Captivia group (14.41%) in patients with type III arch (P = 0.039). CONCLUSIONS Both Valiant Captivia thoracic stent graft and CTAG thoracic endoprosthesis can be safely performed for acute TBAD with low operative mortality, favorable mid-term survival and freedom from reintervention. CTAG thoracic endoprosthesis had fewer dSINE even with larger oversizing and potentially suitable for type III arch with fewer type Ia endoleaks.

J Vasc Surg 2023; 77:1016-1027.e9. [PMID: 36410607 DOI: 10.1016/j.jvs.2022.11.048] [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: 07/08/2022] [Revised: 11/10/2022] [Accepted: 11/14/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE In the present report, we have described the outcomes of endovascular repair, hybrid arch repair, and open surgical repair for type B dissection involving the aortic arch (B1-2, D). METHODS Cases of endovascular repair, hybrid arch repair, and open surgical repair performed between January 2015 and December 2019 for aortic dissection designated as B1-2, D by the Society for Vascular Surgery/Society of Thoracic Surgeons classification were retrospectively analyzed. The primary end point was all-cause mortality at follow-up. The secondary end points included early mortality, early morbidities, and aortic-related late events. Kaplan-Meier curves were created to analyze survival from all-cause mortality and freedom from aortic-related late events in the endovascular, hybrid, and open groups. Propensity score matching and stratification (stratified by proximal dissection extension: B1, D and B2, D) were performed as sensitivity analyses to compare the outcomes among the three treatment patterns after controlling for major confounders. RESULTS The present study included 151 patients (men, 79.5%; mean age, 47.3 ± 10.5 years), with 72 (47.7%) in the endovascular group, 46 (30.5%) in the hybrid group, and 33 (21.8%) in the open group. No significant difference was noted in early mortality between the endovascular, hybrid, and open groups (1.4% vs 2.2% vs 3.0%; P = .791). The incidence of early endoleak was significantly greater (33.3% vs 13.0% vs 6.1%; P = .002) and the incidence of renal function deterioration was less (4.2% vs 26.1% vs 24.2%; P = .001) after endovascular repair vs hybrid arch repair and open surgery. After a median follow-up of 40.0 months (range, 0-84.0 months), no significant differences were found in all-cause mortality (5.6% vs 4.3% vs 3.0%; P = 1.0), aortic-related late events (16.7% vs 15.2% vs 12.1%; P = .834), or late endoleak (9.7% vs 4.3% vs 6.1%; P = .630) after endovascular, hybrid, and open surgery. The propensity score matching and stratification analyses displayed consistent outcomes for early mortality, all-cause mortality, and aortic-related late events among the three groups. CONCLUSIONS The mid- to long-term outcomes after endovascular repair, hybrid arch repair, and open surgical repair for type B dissection involving the aortic arch (B1-2, D) were favorable and comparable in selected patients. Extensive experience and multidisciplinary teamwork are prerequisites for individualized strategies for repair of B1-2, D.

Role of initial medical treatment and effectiveness of thoracic endovascular aortic repair for acute type a aortic dissection with thrombosed false lumen. Eur J Cardiothorac Surg 2023; 63:7085601.

Abstract
OBJECTIVES The optimal treatment for acute type A aortic dissection (AAAD) with thrombosed false lumen (T-FL) of the ascending aorta remains controversial. This study aimed to the evaluate clinical outcomes of initial medical treatment (IMT) and the effectiveness of thoracic endovascular aortic repair (TEVAR) for AAAD with T-FL. METHODS We retrospectively analysed 60 AAAD with T-FL patients. Emergent aortic repair was performed in 33 patients and IMT was selected in 27 uncomplicated patients with ascending aortic diameter < 50 mm and ascending T-FL thickness ≤ 10 mm. RESULTS Among the 27 patients who received IMT, 14 had intramural haematoma at admission; however, new ulcer-like projections appeared in 7 (50%) during hospitalization. Before discharge, 12 (44%) were treated with only medical treatment and 15 (56%) required delayed aortic repair including TEVAR in 8 and open repair in 7. The median interval from onset to delayed repair was 9 days and significantly more patients received TEVAR compared to those receiving emergent repair (53% vs 21%; P = 0.043). Between TEVAR (n = 15) and open repair (n = 33), one (7%) 30-day mortality occurred in TEVAR, whereas no in-hospital mortality occurred in open repair. During the median follow-up time of 24.8 months, no aorta-related death was observed and there were no statistically significant differences in the freedom rate from aortic events (TEVAR: 92.8%/3 years vs open repair: 88.4%/3 years; P = 0.871). CONCLUSIONS Our management with a combination of emergent aortic repair, IMT, and delayed aortic repair for AAAD with T-FL achieved favourable clinical outcomes. In the selected Japanese patients, IMT with repeated MDCT could detect a new intimal tear which could be closed by TEVAR in some cases and TEVAR for this pathology resulted in acceptable early and mid-term outcomes. Further investigations are required to validate the safety and efficacy of this management.

Abstract
BACKGROUND Aortic pseudoaneurysm is a life-threatening clinical condition, and thoracic endovascular aortic repair (TEVAR) has been reported to have a relatively satisfactory effect in aortic pathologies. We summarized our single-centre experience using chimney TEVAR for aortic arch pseudoaneurysms with inadequate landing zones. METHODS A retrospective study was conducted from October 2015 to August 2020, 32 patients with aortic arch pseudoaneurysms underwent chimney TEVAR to exclude an aortic lesion and reconstruct the supra-aortic branches, including 3 innominate artery, 12 left common carotid arteries and 29 left subclavian arteries. Follow-up computed tomography was suggested before discharge; at 3, 6, 12 months and yearly thereafter. RESULTS The median age of 32 patients was 68.0 years (range, 28-81) with the mean max diameter of aneurysm of 47.9 ± 12.0 mm. Forty-four related supra-aortic branches were well preserved, and the technical success rate was 100%. The Type Ia endoleaks occurred in 3 (9%) patients. Two patients were lost to follow-up and 4 patients died during the follow-up period. The mean follow-up times was 46.5 ± 14.3 months. One patient died due to acute myocardial infarction just 10 days after chimney TEVAR and the other 3 patients passed away at 1.5 months, 20 months, and 31 months with non-aortic reasons. The 4.5-year survival estimate was 84.4%. The primary patency rate of the target supra-arch branch vessels was 97.7% (43/44), and no other aorta-related reinterventions and severe complications occurred. CONCLUSION For aortic arch pseudoaneurysms with inadequate landing zones for TEVAR, the chimney technique seems to be feasible, with acceptable mid-term outcomes, and it could serve as an alternative minimally invasive approach to extend the landing zone. Slow flow type Ia endoleak could be treated conservatively after chimney TEVAR. Additional experience is needed, and the long-term durability of chimney TEVAR requires further follow-up.

Abstract
BACKGROUND It is uncertain whether preoperative anemia is independently associated with thoracic endovascular aortic repair (TEVAR) outcomes. Using a national vascular surgery database, we evaluated the associations between preoperative anemia and 30-day mortality, postoperative complications, and 1-year survival for patients undergoing TEVAR. METHODS We retrospectively analyzed all patients in the Vascular Quality Initiative who had undergone TEVAR for aortic dissection, aortic aneurysm, penetrating aortic ulcer, hematoma, or thrombus between January 2011 and December 2019. We excluded patients with a ruptured aneurysm, traumatic dissection, emergent repair, treated aorta distal to zone 5, polycythemia, transfusion of >4 U of packed red blood cells intraoperatively or postoperatively, and missing data on hemoglobin level or surgical indications. The final study cohort was dichotomized into two groups: normal/mild anemia (women, ≥10 g/dL; men, ≥12 g/dL) and moderate/severe anemia (women, <10 g/dL; male, <12 g/dL). Propensity scores by stratification were used to control for confounding in the analysis of the association between the outcomes of 30-day mortality, postoperative complications, and 1-year survival and a binary indicator variable of moderate/severe anemia vs normal/mild anemia. Kaplan-Meier analysis and log-rank tests were used to compare the 1-year survival between the two groups. A Cox regression model was fitted to assess the associations between anemia and survival outcomes. RESULTS A total of 3391 patients were analyzed, 958 (28.3%) of whom had had moderate/severe anemia. After adjustment for multiple clinical factors using propensity score stratification, moderate/severe anemia was associated with a 141% increased odds of 30-day mortality (adjusted odds ratio [aOR], 2.41; 95% confidence interval [CI], 1.15-5.05; P = .019), 58% increased odds of any in-hospital complication (aOR, 1.58; 95% CI, 1.17-2.13; P = .003), 281% increased odds of intraoperative transfusion (aOR, 3.81; 95% CI, 2.68-5.53; P < .001). In addition, moderate/severe anemia was associated with significantly worse survival within the first year after TEVAR (log-rank P < .001; 1-year survival rate using Kaplan-Meier estimates, 86.4% ± 1.3% standard error vs 92.5% ± 0.6% standard error) and with an increased risk of mortality in the first postoperative year (adjusted hazard ratio, 1.81; 95% CI, 1.16-2.82; P = .009). CONCLUSIONS We found that moderate or severe anemia is associated with significantly increased odds of mortality, postoperative complications, and worse 1-year survival after TEVAR. Future studies are needed to evaluate the effect of anemia correction on the outcomes of TEVAR.

Abstract
INTRODUCTION Studies on the mid and long-term outcomes of thoracic endovascular aortic repair (TEVAR) are scarce. This study aimed to investigate the long-term outcomes of TEVAR for all-comers patients with various types of thoracic aortic pathologies, predominantly thoracic aortic dissections and thoracic aortic aneurysms. METHODS Between January 2005 and December 2015, 123 consecutive patients with thoracic aortic pathologies underwent TEVAR. The patients were divided into groups based on aortic pathologies (dissections or aneurysms) and the type of procedure (hybrid TEVAR or non-hybrid TEVAR). Mortality, complications, and reintervention rates were compared between these four groups. The Kaplan-Meier curve and the Cox regression analysis were employed to estimate survivals and factors associated with 5-year mortality. RESULTS One hundred twenty-three consecutive patients with various aortic pathologies undergoing TEVAR were evaluated. Hypertension (79.7 %) and smoking (39 %) were the most common comorbidities in the study population. The patients were followed up for a mean duration of 58.1 ± 7.1 months to evaluate the postprocedural surveillance. Most complications occurred in the dissection and hybrid groups; however, these differences were nonsignificant. The overall 5-year surveillance and reintervention rates were 65 % and 12.1 %, respectively. A significant difference existed in 5-year survival between the patients with aneurysmal and aortic dissection pathologies based on the log-rank test (P = 0.01). On the other hand, no significant differences were observed in 5-year survival between the patients who underwent hybrid and non-hybrid TEVAR. The Cox regression analysis confirmed that chronic kidney disease, previous coronary artery bypass grafting, age >65 years, platelet counts <150∗ 103/μL, aneurysmal aortic pathology, and ejection fraction ≤ 50 % were predictors of 5-year mortality. CONCLUSIONS The long-term outcomes of TEVAR for various aortic pathologies disclosed that this procedure was well-tolerated in a group of patients with high comorbid conditions. The five-year survival rate of TEVAR for thoracic aortic dissections was more favorable than that for thoracic aortic aneurysms, but there were no significant differences between hybrid and non-hybrid procedures regarding the mortality rate.

Readmission after early thoracic endovascular aortic repair versus medical management of acute type B aortic dissection. J Vasc Surg 2023; 77:1387-1393. [PMID: 36646334 DOI: 10.1016/j.jvs.2022.12.064] [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: 10/02/2022] [Revised: 12/06/2022] [Accepted: 12/12/2022] [Indexed: 01/15/2023]
Abstract
BACKGROUND The use of thoracic endovascular aortic repair (TEVAR) for the management of acute uncomplicated type B aortic dissection (TBAD) has increased. Although the results from early studies were promising, larger randomized trials evaluating TEVAR are lacking. It is also unclear where sufficient equipoise exists for such trials. In the present study, we evaluated the number of readmissions and unplanned operations after TEVAR vs those after medical management as the initial treatment of acute uncomplicated TBAD and the frequency of each treatment in this population. METHODS We performed a multi-institutional retrospective review of patients with acute TBAD from 2015 to 2020 with the 1-year outcomes available, excluding patients with prior aortic intervention or chronic, iatrogenic or traumatic etiologies. The primary exposure was TEVAR vs medical management at the index admission. The patient demographics, clinical presentation, and imaging findings were analyzed using bivariate and multivariate logistic regression for the primary outcomes of unplanned readmission and/or operation after the initial admission. The secondary outcomes were mortality, myocardial infarction, stroke, renal failure requiring dialysis, retrograde type A dissection, and length of stay. We hypothesized that the readmissions would be higher with medical management. RESULTS A total of 216 patients with TBAD (47 with complicated and 169 with uncomplicated) from two large academic centers were identified. Of the 169 patients with uncomplicated TBAD, 83 (49%) had been treated medically and 86 (51%) had undergone TEVAR at the initial admission. No differences were found in the demographics or high-risk imaging features at presentation. The medically managed patients had had higher rates of unplanned readmission (34% vs 9%; P = .0001) and operation (28% vs 8%; P = .0007) but shorter lengths of stay (6.3 vs 13.1 days; P < .0001). No differences were found in mortality, although the rate of myocardial infarction was higher in the medically managed group (10.8% vs 2.3%; P = .02). Although 28% of the medically managed patients had later required operation, they had had morbidity and mortality similar to those of patients who had undergone initial TEVAR. Initial medical management was associated with unplanned readmission (odds ratio, 8.3; P = .02) and the need for operation (odds ratio, 4.56; P = .006). No differences were found in the outcomes according to the involved aortic zones. CONCLUSIONS In the present study, medical management of acute uncomplicated TBAD was associated with higher rates of readmission and the need for unplanned operation compared with TEVAR. However, no differences were found in the 1-year mortality for the patients for whom medical management had failed. Because one half of the patients had undergone medical management and one half had undergone early TEVAR, this finding suggests clinical equipoise for the treatment of acute uncomplicated TBAD. Therefore, a larger randomized trial appears warranted to determine whether a clear benefit exists for early TEVAR.

Differences of mid-term outcomes in debranching thoracic endovascular aortic repair between zone 0 and zone 1-2 landing. Gen Thorac Cardiovasc Surg 2023; 71:59-66. [PMID: 35900663 DOI: 10.1007/s11748-022-01852-0] [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: 05/15/2022] [Accepted: 06/27/2022] [Indexed: 01/07/2023]
Abstract
OBJECTIVE Debranching thoracic endovascular aortic repair (d-TEVAR) for zone 0 landing (Z0-TEVAR) remained challenging in aortic arch aneurysms. This study aimed to compare the mid-term outcomes between Z0-TEVAR and Z1/2-TEVAR to assess the appropriateness of Z0-TEVAR as the first-line therapy for aortic arch aneurysms in high-risk patients. METHODS Medical records of 200 patients who underwent d-TEVAR from 2007 to 2019 were retrospectively reviewed. Of these, 40 patients who underwent Z0-TEVAR (70% males; the median age of 82 years) and 160 Z1/2-TEVAR (78% males; the median age of 77 years) were compared. In each group, 39 patients were matched using propensity scores (PS) to adjust for differences in patient backgrounds. RESULTS Freedom from all-cause mortality (p < 0.001), aorta-related mortality (p < 0.001), and stroke (p = 0.001) were significantly lower in Z0-TEVAR than in Z1/2-TEVAR. Freedom from reintervention was similar between the two groups (p = 0.326). Type A dissection post-TEVAR was observed in 3 (7.5%) of Z0-TEVAR, but none in Z1/2-TEVAR (p = 0.006). Pneumonia was also more frequent in Z0-TEVAR (n = 8, 30%) than Z1/2-TEVAR (n = 4, 2.5%) (p < 0.001). PS matching also yielded worse outcomes (all-cause mortality, p = 0.017; aorta-related mortality, p = 0.046; and stroke, p = 0.027) in Z0-TEVAR than Z1/2-TEVAR. CONCLUSIONS Higher mid-term mortality and stroke rates after Z0-TEVAR were confirmed by PS matching. Z0-TEVAR would be an alternative for high-risk patients with arch aneurysms requiring zone 0 landing but not a reliable method.

Abstract
We performed a contemporary assessment of clinical and radiographic factors of stroke after thoracic endovascular aortic repair (TEVAR). Patients undergoing TEVAR from 2006 to 2017 were identified. We assessed clinical and radiographic data, including preoperative head and neck computed tomography, Doppler ultrasonography, and intraoperative angiography. Our primary outcome was stroke after TEVAR. Four hundred seventy-nine patients underwent TEVAR, mean age 68.1 ± 19.5 years, 52.6% male. Indications for TEVAR included aneurysms (n = 238, 49.7%) or dissections (n = 152, 31.7%). Ishimaru landing zones were Zone 2 (n = 225, 47.0%), Zone 3 (n = 151, 31.5%), or Zone 4 (n = 103, 21.5%). Stroke occurred in 3.8% (n = 18) of patients, with 1.9% (8) major events (modified Rankin Scale >3). Pathophysiology was predominantly embolic (n = 14), and occurred in posterior (n = 6), anterior (n = 6), or combined circulation (n = 4), and in the left hemisphere (n = 10) or bilateral (n = 6). Univariate analysis suggested use of lumbar drain (33.3% versus 57.2%, P = 0.04), inability to revascularize the left subclavian artery (16.7% vs 5.2%, P = 0.04) and number of implanted components (2.5 ± 1.2 vs 2.0 ± 0.97, P = 0.03) were associated with stroke. Multivariable analysis identified number of implanted components (OR 1.7, 95%CI 1.17-2.67 P = 0.00) and inability to revascularize the left subclavian artery as independent predictors of stroke. Stroke was associated with a higher perioperative mortality (27.8% vs 3.9%, P < 0.01). Stroke after TEVAR is primarily embolic in nature and related to both anatomic and procedural factors. This may have important implications for device development in the era of endovascular arch repair.

Abstract
Complex anatomical restrictions can lead to further interventions after the emergence of a postoperative aneurysm enlargement in thoracic endovascular aortic repair (TEVAR) for a thoracoabdominal aortic aneurysm (TAAA). A 75-year-old male underwent a TEVAR for a Crawford extent I TAAA. The main device and the distal extension were placed using a fenestrated technique, outside of the instructions for use. The aneurysm expanded because of an endoleak and stent graft migration; and was surgically repaired by fully salvaging the previous endografts 38 months after the first TEVAR. However, the distal extension, which was the proximal anastomosis site with a prosthetic graft, became completely dislocated from the main device eight months after the open surgical conversion, resulting again in the enlargement of the aneurysm. An additional TEVAR was successfully performed to correct the dislocated stent graft. An appropriate treatment strategy is crucial to prevent multiple reinterventions for TAAA with complex anatomical restrictions.

Abstract
BACKGROUND Blunt thoracic aortic injury is one of the most lethal traumatic injuries. Ruptured cases often result in cardiac arrest before arrival at the hospital, and survival is rare. CASE PRESENTATION A female patient in her 30 s was struck by an automobile while she was walking across an intersection. She was in a state of shock when emergency services arrived and was in cardiac arrest shortly after arriving at the hospital. A left anterolateral thoracotomy revealed a massive hemothorax secondary to thoracic aortic rupture. In addition, the patient had multiple traumas, including maxillary, pelvic, and lumbar burst fractures. We attempted to directly suture the aortic lesion; however, the increasing blood pressure caused the suture to break. We used a thoracic stent graft while ensuring permissive hypotension. Her postoperative prognosis was positive, and she was transferred to another hospital 85 days later. CONCLUSIONS We successfully performed a hybrid surgery combining thoracotomy and endovascular repair for this emergency case of blunt thoracic aortic injury with rupture.

Abstract
OBJECTIVE Most of the entry tears of uncomplicated type B aortic dissection are located in the distal arch and extends in a retrograde manner to the level of the left subclavian artery. Our objective was to evaluate feasibility and effectiveness using fenestrated sent graft with complete neck vessel preservation to treat uncomplicated type B aortic dissection. SUBJECTS AND METHODS We retrospectively reviewed the record of patients with uncomplicated type B aortic dissection who underwent fenestrated thoracic endovascular aortic repair in subacute phase (15-90 days) between August 2016 and April 2020. The Najuta fenestrated stent graft was placed proximally beyond he left subclavian artery (zone 0-2) in an attempt to seal the entry while preserving the neck vessels. RESULTS We evaluated 9 cases (male: 7, female: 2; median age 70 years). The median distance from the LSA to the proximal entry was 37 mm. The landing zones of the proximal end of the Najuta were zone 0: 3, zone 1: 2, and zone 2: 4 cases. Technical success was 100% with no 30-day death. None of the patients had a stroke, paraplegia or retrograde dissection, and no endoleak was observed. Complete aortic remodeling with false lumen resolution was obtained in all cases while each fenestrated vessels remained patent during the follow-up period. CONCLUSION Preemptive thoracic endovascular aortic repair aimed at perfusion of cervical branches using the Najuta fenestrated stent is safe and effective and may be considered as a reasonable treatment option for the treatment is a safe and an effective treatment.
