The Complementary Roles of Open and Endovascular Repair of Extent I - III Thoraco-abdominal Aortic Aneurysms in a United Kingdom Aortic Centre. Eur J Vasc Endovasc Surg 2024; 68:62-72. [PMID: 38403184 DOI: 10.1016/j.ejvs.2024.02.031] [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: 04/20/2023] [Revised: 02/07/2024] [Accepted: 02/22/2024] [Indexed: 02/27/2024]
Abstract
OBJECTIVE A multidisciplinary approach offering both open surgical repair (OSR) and complex endovascular aortic repair (cEVAR) is essential if patients with thoraco-abdominal aortic aneurysms (TAAAs) are to receive optimal care. This study reports early and midterm outcomes of elective and non-elective OSR and cEVAR for extent I - III TAAA in a UK aortic centre. METHODS Retrospective study of consecutive patients treated between January 2009 and December 2021. Primary endpoint was 30 day/in hospital mortality. Secondary endpoint was Kaplan-Meier estimates of midterm survival. Data are presented as median (interquartile range [IQR]). RESULTS In total, 296 patients (176 men; median age 71 years [IQR 65, 76]; median aneurysm diameter 66 mm [IQR 61, 75]) underwent repair (222 elective, 74 non-elective). OSR patients (n = 66) were significantly younger with a higher incidence of heritable disease and chronic dissection, while cEVAR patients (n = 230) had a significantly higher prevalence of coronary, pulmonary, and renal disease. Overall, in hospital mortality after elective and non-elective repair was 3.2% (n = 7) and 23.0% (n = 17), respectively, with no significant difference between treatment modalities (elective OSR 6.5% vs. cEVAR 2.3%, p = .14; non-elective OSR 25.0% vs. cEVAR 20.3%, p = .80). Major non-fatal complications occurred in 15.3% (33/215) after elective repair (OSR 39.5%, 17/43, vs. cEVAR 9.3%, 16/172; p < .001) and 14% (8/57) after non-elective repair (OSR 26.7%, 4/15, vs. cEVAR 9.5%, 4/42; p = .19). Median follow up was 52 months (IQR 23, 78). Estimated survival ± standard error at 1, 3, and 5 years for the entire cohort was 89.6 ± 2.0%, 76.6 ± 2.9%, and 69.0% ± 3.2% after elective repair, and 67.6 ± 5.4%, 52.1 ± 6.0%, and 41.0 ± 6.2% after non-elective repair. There was no difference in 5 year survival comparing modalities after elective repair for patients younger than 70 years and those with post-dissection aneurysms. CONCLUSION A multidisciplinary approach offering OSR and cEVAR can deliver comprehensive care for extent I - III TAAA with low early mortality and good midterm survival. Further studies are required to determine the optimal complementary roles of each treatment modality.

Abstract
OBJECTIVE The aim of this study was to report the outcomes of endovascular urgent thoracoabdominal aortic (TAAA) repair, using an off-the-shelf preloaded inner branch device (E-nside; Artivion). METHODS Data from a physician-initiated national multicenter registry, including patients treated with E-nside endograft (INBREED) were prospectively collected (2020-2024); only urgent cases were included in this study. Primary outcomes were technical success and mortality at 30 days. Secondary outcomes were spinal cord ischemia rate, stroke rate, major adverse events (MAE) as also branch instability at 12 months. RESULTS Of 185 patients enrolled in the INBREED, 64 (34.5%) were treated in a urgent setting and were included in the study. Reason for urgent repair was presence of aneurysm-related symptoms in 31 patients (48.4%), a contained rupture in eight (12.5%), and a large aneurysm >80 mm in 25 (39.1%). Extent of repair was I to III in 32 patients (50%) and IV in 32 (50%); 18 (28%) had a narrow (<25 mm) paravisceral aortic lumen. An adjunctive proximal thoracic endograft was deployed in 29 patients (45.3%); a distal bifurcated abdominal endograft was used in 33 (51.5%). Two hundred forty-nine target vessels (97.2%) were successfully incorporated through an inner branch from an upper arm (81.2%) or femoral (18.8%) access. A balloon expandable stent was used in 184 (75.7%) target vessels, a self-expandable stent in 59 (24.3%). Mean time for target vessel bridging was 39.9 ± 28.4 minutes per target vessel. Thirty-day cumulative major adverse event (MAE) rate was 28%, and mortality occurred in five patients (9.1%). There was one postoperative stroke (1.6%), and the spinal cord ischemia (SCI) rate was 8% (n = 5). For the 249 target vessels successfully incorporated through an inner branch, 1-year freedom from target vessel instability was 93% ± 3% after 1 year. CONCLUSIONS The E-nside represents a valid solution for the urgent treatment of TAAAs, including symptomatic and ruptured TAAAs, as well as large asymptomatic TAAAs that cannot wait for a custom-made device. The preloaded inner branches and available proximal and distal graft diameters might be useful in urgent settings and provided satisfactory early and 1-year results, in terms of both endograft and target vessel stability. Further studies are required to assess the clinical role of E-nside for urgent TAAA repair.

Abstract
PURPOSE The purpose was to describe a technique to promote false lumen (FL) thrombosis in post-dissection thoracoabdominal aortic aneurysms (PD-TAAAs) managed by fenestrated/branched endografting (F/B-EVAR). TECHNIQUE A 5/6Fr-90 cm length sheath is advanced from the true lumen (TL) to FL through the most distal entry tear of the infrarenal aorta or iliac arteries. It is parked in the most cranial portion of the FL in the thoracic aorta. Aortic endografts are deployed in the TL excluding all the para-visceral/distal entry tears and target visceral vessels bridging stenting is performed. A selective FL angiography is performed through the 5/6Fr sheath to detect the origin of all segmentary arteries. Embolization of FL is performed from above to below by M-reye pushable coils, obtaining the packaging of FL. After completion angiography, the 5/6Fr sheath is retrieved in external iliac artery and molding ballooning of the distal segment of the aortic/iliac endograft is performed. Between 2019 and 2023, this technique was applied in 11cases with a median number of 73 (interquartile range [IQR=12) coils. Out of 8 (72%) patients with available radiological follow-up at 1 year, 7 exhibited complete FL thrombosis. CONCLUSIONS The FL coiling in PD-TAAAs managed by F/B-EVAR is feasible, safe, and effective to promote the complete FL thrombosis. CLINICAL IMPACT Preemptive false lumen embolization is a feasible, safe, and effective technique for preventing persistent type II endoleaks after fenestrated-branched endovascular repair of post-dissection thoracoabdominal aortic aneurysms. This technique may be routinely recommended to promote FL thrombosis and aortic remodeling after FB-EVAR in PD-TAAAs, thereby reducing the incidence of reinterventions during follow-up.

Abstract
OBJECTIVE To evaluate the early and mid-term outcomes of open repair in patients with thoracoabdominal aortic aneurysm (TAAA) after thoracic endovascular aortic repair (TEVAR). METHODS This was a retrospective single center study. Data were retrospectively collected and analyzed for consecutive patients undergoing open TAAA repair (TAAAR) after TEVAR from November 2016 to June 2021. Indications for TAAAR included aneurysm progression due to endoleak, persisted false lumen perfusion, proximal/distal disease progression, and aorta rupture. The risk factor of operative mortality was analyzed by multivariable logistic regression model and the survival was evaluated by Kaplan-Meier. RESULTS Sixty-three patients who met the inclusion criteria for the study were identified. The mean age at TAAAR was 41 ± 12 years and 43 (68.3%) were male. Marfan syndrome (MFS) was presented in 39 patients (61.9%). 60 (95.2%) patients presented with post-dissection aneurysm and 3 (4.8%) patients with degenerative aneurysm. The extent of TAAA was Crawford I in 9 (14.3%), II in 22 (34.9%), III in 23 (36.5%), and IV in 9 (14.3%). Emergent TAAAR was done in 10 (15.9%) patients, and deep hypothermic circulatory arrest was used in 22 (34.6%). Endograft was explanted in 31 (49.2%). Operative mortality was 11 (17.5%). Stroke, paraplegia, and acute kidney failure occurred in 5 (7.9%), 7 (11.1%), and 6 (9.5%) patients, respectively. Pulmonary complications occurred in 19 (30.2%) patients. The estimated survival was 74.8 ± 4.9% at 5 years. Late reoperations were performed in 2 patients at 2.5 years and 1.3 years, respectively. CONCLUSIONS In this series of TAAA after TEVAR, TAAAR was related with a high risk of operative mortality and morbidity and the midterm outcomes represented a durable treatment and were respectable.

Early and midterm outcomes of fenestrated and branched endovascular aortic repair in thoracoabdominal aneurysms types I through III. J Vasc Surg 2024; 79:457-468.e2. [PMID: 38453660 DOI: 10.1016/j.jvs.2023.10.043] [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: 08/24/2023] [Revised: 10/09/2023] [Accepted: 10/10/2023] [Indexed: 03/09/2024]
Abstract
BACKGROUND Fenestrated and branched endovascular aortic repair (F/BEVAR) of thoracoabdominal aortic aneurysms (TAAAs) has shown high technical success and low early mortality rates. Aneurysm extent has been reported as a factor affecting outcomes. This study aimed to assess the early and midterm follow-up outcomes of patients managed by F/BEVAR for types I through III TAAAs. METHODS A single-center retrospective analysis was conducted, including data from consecutive, elective and urgent (symptomatic and ruptured cases), patients treated for types I through III TAAAs, between October 1, 2011, and October 1, 2022, using F/BEVAR. Degenerative and postdissection TAAAs were included. Patients received prophylactic cerebrospinal fluid drainage (CSFD), except those under therapeutic anticoagulation, those who were hemodynamically unstable, or those with failed CSFD application. When an initial thoracic endovascular aortic repair was performed, as part of a staged procedure, no CSFD was used. Later stages and nonstaged procedures were performed under CSFD. Thirty-day mortality and major adverse events (MAEs) were analyzed. Kaplan-Meier estimates were used for follow-up outcomes. RESULTS F/BEVAR for types I through III TAAAs was performed in 209 patients (56.9% males; mean age, 69.6 ± 3.2 years; mean aneurysm diameter, 65.2 ± 6.2 mm); 29.2% type I, 57.9% type II, and 12.9% type III. Urgent repair was performed in 26.7% of patients (56 cases; 23 ruptured and 33 symptomatic cases) and 153 were treated electively. Thirty-two patients (15.3%) were classified as American Society of Anesthesiologists (ASA) class IV. CSFD was used in 91% and staged thoracic endovascular aortic repair was performed in 51.2% of patients. Technical success was 93.8% (96.7% in elective vs 94.6% in urgent cases; P = .92). Thirty-day mortality was 11.0% (4.6% in elective vs 28.5% in urgent cases; P < .001) and MAEs were recorded in 17.2% of cases (7.8% in elective vs 42.8% in urgent cases; P < .001). Spinal cord ischemia rate was 20.5% (17.6% in elective vs 28.7% in urgent cases; P = .08), whereas 2.9% of patients presented paraplegia (1.3% in elective and 7.1% in urgent cases; P = .03). The mean follow-up was 16 ± 5 months. Survival was 75.0% (standard error, 4.0%) and freedom from reintervention was 73.3% (standard error, 4.4%) at 36 months. ASA IV and urgent repair were detected as independent factors related to early mortality and MAE, whereas ruptured aneurysm status was related to spinal cord ischemia evolution. CONCLUSIONS Endovascular repair for types I through III TAAAs provides encouraging early outcomes in terms of mortality, MAE, and paraplegia, especially in an elective setting. Setting of repair and baseline ASA score should be taken into consideration during decision-making.

Abstract
Spinal cord ischemia/reperfusion injury (SCIRI) induced by artificial aortic occlusion for a while during aortic surgery is a serious complication, leading to paraplegia and even death. Ferroptosis in the nervous system has been confirmed to contribute to neuronal death induced by SCIRI. Therefore, we investigated the therapeutic benefits of ferrostatin-1 (Fer-1, a ferroptosis inhibitor) and explored the mechanism and target of Fer-1 in SCIRI. Our results demonstrate that intrathecal injection of Fer-1 had a strong anti-SCIRI effect, improved ferroptosis-related indices, increased neurological function scores and motor neuron counts, and reduced BSCB leakage and neuroinflammation levels in the anterior horn. We found that SCIRI significantly elevated the levels of several important proteins, including SP1, p-ERK1/2/ERK1/2, COX2, TFR1, SLC40A1, SLC7A11, cleaved Caspase 3, GFAP, and Iba1, while reducing FTH1 and GPX4 protein expression, with no effect on ACSL4 expression. Fer-1 effectively ameliorated the ferroptosis-related changes in these proteins induced by SCIRI. However, for p-ERK1/2 and SP1, Fer-1 not only failed to reduce their expression but also significantly enhanced it. Fer-1 was injected into sham operation rats, abnormal increases in p-ERK1/2/ERK1/2 and SP1 were observed, along with an increase in GPX4. Fluorescent double labeling revealed that SP1 and GPX4 were expressed in neurons and astrocytes. Inhibitors of the ERK pathway (SCH772984) and siRNA against SP1 (AV-sh-SP1) significantly decreased the increase in SP1 and GPX4 protein levels, fluorescent density of SP1 and GPX4 in neurons, and the number of SP1-positive and GPX4-positive neurons induced by Fer-1. SCH772984 but not AV-sh-SP1 significantly reversed the decrease in GFAP and Iba1 induced by Fer-1. In conclusion, our results indicate that Fer-1 inhibited ferroptosis in spinal cord anterior horn neurons, improving neurological impairment and BSCB damage after SCIRI through the ERK1/2/SP1/GPX4 signaling pathway in rats.

Abstract
Background: Open thoracoabdominal aortic aneurysm (TAAA) repair is often related to significant morbidity and complications like paraplegia or acute kidney injury. Subsequently, prolonged intensive care stay is common. However, there is a lack of research on post-traumatic stress disorder (PTSD) and the perceived quality of life (QOL) in patients undergoing complex aortic procedures, such as open TAAA repair. Therefore, our study aims to determine the prevalence of PTSD and the current QOLin these patients and whether it is associated with demographic factors or complications following open thoracoabdominal aortic repair. Patients and methods: In this retrospective study, a total of 213 adult surviving patients after open thoracoabdominal aortic repair were contacted with two questionnaires one to assess PTSD and another to evaluate current QOL after open thoracoabdominal aortic repair. 61 patients returned one or both the questionnaires, and 59 patients (97%) answered all questions of the 4-item primary care PTSD section of the survey. In addition to the PTSD screening, patients were sent an SF-36 questionnaire to assess their current quality of life. 60 patients answered the SF-36 questionnaire partially or completely (98%). Results: 27% of patients (16/59) screened positive for PTSD. Electronic medical records were matched to all responding patients. Patients who were screened positive for PTSD spent more days in intensive care (OR, 1.073; 95% CI 1.02-1.13; p=0.005), had a higher frequency of tracheotomy (OR, 6.43; 95% CI 1.87-22.06; p=0.004), sepsis (OR, 5.63; 95% CI 1.56-20.33; p=0.014), as well as postoperative paraparesis (OR, 13.23; 95% CI 1.36-129.02; p=0.019). In patients with postoperative complications, a statistically significant decrease in the overall score was observed for certain categories of the SF-36. Conclusions: The prevalence of PTSD is higher, in comparison to the general population's prevalence, and the quality of life is affected following open thoracoabdominal aortic aneurysm repair, with a significant relation to postoperative complications as well as the length of ICU stay. Further research and screening for PTSD in relation to open TAAA repair is needed to assess its role in patient QOL during follow up.

Abstract
Background: Acute kidney injury (AKI) after open thoracoabdominal aortic aneurysm repairs (TAAA) is a common postoperative complication, associated with increased mortality and morbidity. Early detection and management of the kidney tissue damage remains of paramount importance. The aim of this prospectively conducted, observational trial was to evaluate the clinical applicability of Proenkephalin A 119-159 (penKid) for the detection of postoperative AKI. Patients and methods: Thirty-six patients, planned for elective open TAAA repairs from January 2019 to December 2022, were recruited in two German centres (University Hospital Aachen and Charité - University Hospital Berlin). Blood samples were collected pre-surgery (baseline), directly postoperatively and at 12, 24 and 48 hours after surgery. The penKid concentration in plasma was measured using the immunoluminometric sphingotest® assay kit and they were statistically tested for association with AKI and other clinical parameters. Results: Twenty-four patients (62%) developed moderate or severe AKI postoperatively (Stage 2 or 3 of the KDIGO classification) and they had a significantly increased risk for the development of acute respiratory distress syndrome (p=.023) or a fatal outcome (p=.035). Starting from the 12th hour after surgery, we found penKid correlating with AKI stage 2/3 (12 hour penKid mean in pmol/L: 93.9 vs. 43.1; c index .776, p=.0037) and renal replacement therapy (12 hour c index .779, p=.0035). Patients with multi-organ dysfunction syndrome had significantly increased penKid levels at all timepoints. Conclusions: We found penKid to be a promising biomarker for the early detection of postoperative AKI and in-hospital mortality after open TAAA repair, which may enable the early initiation of organ-protective strategies and reduction of further complications associated with AKI.

Forootan S, Danaei S, Hajebrahimi S, Najafi B, Asghari-Jafarabadi M, Janati A. Compensation based on work relative value unit for cardiovascular surgeons in Iran: A mixed method study. JOURNAL OF EDUCATION AND HEALTH PROMOTION 2023; 12:354. [PMID: 38144030 PMCID: PMC10743844 DOI: 10.4103/jehp.jehp_1381_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Accepted: 12/02/2022] [Indexed: 12/26/2023]
Abstract
BACKGROUND Work relative value unit (wRVU) is a tool for assessing surgeons' performance, compensation, and productivity. It appears that wRVU for cardiovascular procedures does not consider complexity and its value for lengthy operations is low. The aim of the study is to determine wRVU for cardiovascular procedures in Iran according to the proposed approach. MATTERIALS AND METHODS This study was conducted as a mixed method in teaching hospitals in Tabriz in the period of September 2020 to December 2021. According to Hospital Information System and expert opinions, six procedures in cardiovascular surgery were included in the study. They were compared with 18 procedures in neurosurgery, orthopedics, and otorhinolaryngology in terms of the operation time and wRVU/min. Then, we calculated new wRVUs for the selected procedures based on surgeons' opinions, time measurements, and anesthetists' points of view by content analysis in qualitative and statistical analysis in quantitative parts. RESULTS Among the six cardiac procedures, the wRVU for five was under-estimated. The wRVU/min value ranged from 0/28 to 1/15 in the studied procedures. Findings demonstrate no significant relationship between the length of operations and the wRVU announced by the Ministry of Health and Medical Education (P value >0/05). Compared to studied procedures in four specialties, thoracoabdominal aortic aneurysm repair has the longest surgery time at 417 minutes. According to anesthesiologists, cardiovascular; orthopedics; ear, nose, and tongue; and neurosurgery specialties obtained 4/2, 2/9, 2/8, and 4, respectively, in terms of surgery duration, complexity, risk, and physical effort. CONCLUSION Despite policymakers' attempts to bring justice to payments, it seems that there has been little progress in paying cardiovascular surgeons. Improper payment to cardiovascular surgeons will affect the future of the workforce in this specialty. Today, the need to reconsider the wRVUs in heart specialty is felt more than before.

Eur J Cardiothorac Surg 2023; 64:ezad338. [PMID: 37847652 DOI: 10.1093/ejcts/ezad338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 09/13/2023] [Indexed: 10/19/2023] Open
Abstract
OBJECTIVES Although recent studies and guidelines suggest the preferred outcomes after surgical repair of thoracic aortic aneurysm (TAA) and thoracoabdominal aortic aneurysm (TAAA), published results are limited to those from high-volume hospitals and based on old data gathered before optimal management was established. Here, we analysed our outcomes over the previous 10 years from cases of open TAA and TAAA repair to offer updated and real-world results of those complex procedures performed in a high-volume centre. METHODS From November 2013 to April 2022, 212 consecutive adult patients who underwent open TAA and TAAA repair were enrolled. We analysed early and late outcomes after surgery, including postoperative complications and mortality. RESULTS There were 154 (73%) men, and the median age at surgery was 61 years. Intraoperative death occurred in 1 patient due to uncontrolled bleeding. Nine patients (4%) died during follow-up, and the survival estimates at 5 years were 94 ± 3% and 95 ± 3% after descending TAA and TAAA repair, respectively. Ten patients (4%) suffered from spinal cord ischaemic injury (9 with paraplegia and 1 with paresthesia), but permanent paraplegia persisted in only 1 case. CONCLUSIONS We report very low postoperative complication rates and excellent early and late survival rates after open TAA and TAAA repair from our recent 10-year data analysis. These findings may assist when choosing treatment options for these complicated diseases.

Systematic Review of the Effect of Cerebrospinal Fluid Drainage on Outcomes After Endovascular Descending Thoracic/Thoraco-Abdominal Aortic Aneurysm Repair. Eur J Vasc Endovasc Surg 2023; 66:501-512. [PMID: 37182608 DOI: 10.1016/j.ejvs.2023.05.006] [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: 10/04/2022] [Revised: 04/07/2023] [Accepted: 05/05/2023] [Indexed: 05/16/2023]
Abstract
OBJECTIVE This study aimed to investigate whether prophylactic use of cerebrospinal fluid (CSF) drainage in endovascular descending thoracic aortic aneurysm (DTAA) and thoraco-abdominal aortic aneurysm (TAAA) repair contributes to a lower rate of post-operative spinal cord ischaemia (SCI). DATA SOURCES MEDLINE, Embase, and CINAHL. REVIEW METHODS A literature review was conducted in accordance with PRISMA guidelines (PROSPERO registration no. CRD42021245893). Risk of bias was assessed through the Newcastle-Ottawa scale (NOS), and the certainty of evidence was graded using the GRADE approach. A proportion meta-analysis was conducted to calculate the pooled rate and 95% confidence interval (CI) of both early and late onset SCI. Pooled outcome estimates were calculated using the odds ratio (OR) and associated 95% CI. The primary outcome was SCI, both early and lateonset. Secondary outcomes were complications of CSF drainage, length of hospital stay, and peri-operative (30 day or in hospital) mortality rates. RESULTS Twenty-eight observational, retrospective studies were included, reporting 4 814 patients (2 599 patients with and 2 215 without CSF drainage). The NOS showed a moderate risk of bias. The incidence of SCI was similar in patients with CSF drainage (0.05, 95% CI 0.03 ‒ 0.08) and without CSF drainage (0.05, 95% CI 0.00 ‒ 0.14). No significant decrease in SCI was found when using CSF drainage (OR 0.67, 95% CI 0.29 ‒ 1.55, p = .35). The incidence rate of CSF drainage related complication was 0.10 (95% CI 0.04 ‒ 0.19). The 30 day and in hospital mortality rate with CSF drainage was 0.08 (95% CI 0.05 ‒ 0.12). The 30 day and in hospital mortality rate without CSF drainage and comparison with late mortality and length of hospital stay could not be determined due to lack of data. The quality of evidence was considered very low. CONCLUSION Pre-operative CSF drainage placement was not related to a favourable outcome regarding SCI rate in endovascular TAAA and DTAA repair. Due to the low quality of evidence, no clear recommendation on pre-operative use of CSF drainage placement can be made.

Hospital Incidence, Treatment, and Outcome of 885 Patients with Thoracoabdominal Aortic Aneurysms Treated in Switzerland over 10 Years-A Secondary Analysis of Swiss DRG Data. J Clin Med 2023; 12:5213. [PMID: 37629255 PMCID: PMC10455290 DOI: 10.3390/jcm12165213] [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: 07/03/2023] [Revised: 08/02/2023] [Accepted: 08/06/2023] [Indexed: 08/27/2023] Open
Abstract
Despite the development of fenestrated and branched endovascular aortic repair (f/bEVAR), the surgical management of thoraco-abdominal aortic aneurysms (TAAAs) remains a major challenge. The aim of this study was to analyse the hospital incidence and hospital mortality of patients treated for TAAAs in Switzerland. Secondary data analysis was performed using nationwide administrative discharge data from 2009-2018. Standardised incidence rates and adjusted mortality rates were calculated. A total of 885 cases were identified (83.2% nonruptured (nrTAAA), 16.8% ruptured (rTAAA)), where 69.3% were male. The hospital incidence rate for nrTAAA was 0.4 per 100,000 women and 0.9 per 100,000 men in 2009, which had doubled for both sexes by 2018. For rTAAA, there was no trend over the years. The most common procedure was f/bEVAR (44.2%), followed by OAR (39.5%), and 9.8% received a hybrid procedure. There was a significant increase in endovascular procedures over time. The all-cause mortality was 7.1% with nrTAAA and 55% with rTAAA. The mortality was lower for rTAAA when f/bEVAR or hybrid procedures were used. A ruptured aneurysm and higher comorbidity were associated with higher hospital mortality. This study demonstrates that the treatment approach has changed significantly over the observed period. The use of f/bEVAR nearly tripled in nrTAAA and doubled in rTAAA during this decade.

Abstract
Acute kidney injury (AKI) is a common complication after complex aortic procedures and it is associated with relevant mortality and morbidity. Biomarkers for early and specific AKI detection are lacking. The aim of this work is to investigate the reliability of the NephroCheck bedside system for diagnosing stage 3 AKI following open aortic surgery. In this prospective, multicenter, observational study,- https://clinicaltrials.gov/ct2/show/NCT04087161 -we included 45 patients undergoing open thoracoabdominal aortic repair. AKI risk (AKIRisk-Index) was calculated from urine samples at 5 timepoints: baseline, immediately postoperatively and at 12, 24, 48, and 72 h post-surgery. AKIs were classified according to the KDIGO criteria. Contributing factors were identified in univariable and multivariable logistic regression. Predictive ability was assessed with the area under the receiver operator curve (ROCAUC). Among 31 patients (68.8%) that developed AKIs, 21 (44.9%) developed stage-3 AKIs, which required dialysis. AKIs were correlated with increased in-hospital mortality (p = .006), respiratory complications (p < .001), sepsis (p < .001), and multi-organ dysfunction syndrome (p < .001). The AKIRisk-Index showed reliable diagnostic accuracy starting at 24 h post-surgery (ROCAUC: .8056, p = .001). In conclusion, starting at 24 h after open aortic repair, the NephroCheck system showed adequate diagnostic accuracy for detecting the patients at risk for stage 3 AKIs.

Abstract
BACKGROUND The efficacy of cytokine adsorption in controlling the early inflammation cascade after open thoracoabdominal aortic (TAAA) repair has not been investigated. The aim of this pilot randomized controlled trial was to assess the feasibility and effect of perioperative hemoadsorption during open TAAA repair. METHODS Patients scheduled for open TAAA repair with the use of cardiopulmonary bypass (CPB) were included. The patients were randomized the day before surgery to either intraoperative hemoadsorption during CPB or standard of care. RESULTS A total of 10 patients were randomly assigned to the intervention group, whereas the control group consisted of 17 patients (mean age of the total cohort, 51.1 ± 11.2 years, 67% male, 3 patients not randomized). The majority of baseline and perioperative characteristics were similar, and no device-related adverse events were reported. A trend to shorter ventilation times in the intervention group was observed (median 88 h vs. 510 h, p = 0.08, Δ422). Severe acute respiratory distress syndrome was significantly less in the intervention patients (p = 0.02). CONCLUSIONS This is the first pilot study showing that the intraoperative use of hemoadsorption in open TAAA repair patients may be feasible and safe, yet larger trials are needed to evaluate whether intraoperative hemoadsorption is associated with improved clinical outcomes.

Onset of Adverse Abdominal Events Due to Intestinal Ischemia-Reperfusion Injury after Aortic Cross-Clamping Is Associated with Elevated HSP70 Serum Levels in the Early Postoperative Phase. Int J Mol Sci 2022; 23:ijms232315063. [PMID: 36499389 PMCID: PMC9736142 DOI: 10.3390/ijms232315063] [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: 10/05/2022] [Revised: 11/18/2022] [Accepted: 11/28/2022] [Indexed: 12/05/2022] Open
Abstract
Tissue injury of the viscera during open thoracoabdominal aortic (TAA) reconstructions has been reported as the aftermath of the ischemia-reperfusion mechanism following supracoeliac aortic cross-clamping. Abdominal complications after open aortic reconstructions, although rare through the intraoperative implementation of selective visceral artery blood perfusion, are associated with high rates of reinterventions and a poor prognosis. Recent animal experiments demonstrated that provoking mesenteric ischemia in rats induces the leukocyte-mediated transcription of heat-shock protein 70 (HSP70), a chaperone belonging to the danger-associated molecular pattern proteins (DAMPs). Translating these findings clinically, we investigated the serum levels of HSP70 in patients undergoing open aortic reconstructions with supracoeliac clamping. We postoperatively observed a relevant induction of HSP70, which remained significantly elevated in cases of postoperative abdominal complications (paralytic ileus, abdominal compartment syndrome, and visceral malperfusion). The receiver-operator curve analysis revealed the reliable prognostic accuracy of HSP70 as a biomarker for these complications as soon as 12 h post-operation (AUC 0.908, sensitivity 88.9%, specificity 83.3%). In conclusion, measuring HSP70 serum levels in the early postoperative phase may serve as a further adjutant in the diagnostic decision making for both the vascular surgeon and intensivist for the timely detection and management of abdominal complications following open TAA surgery.

Abstract
Open thoracoabdominal aortic aneurysm (TAAA) repair is a complex and challenging operation with a high incidence of serious complications, and high perioperative mortality and morbidity. Left heart bypass (LHB) is a circulatory support system used to perfuse the distal aorta during TAAA operation, and the advantages of LHB include guaranteeing distal perfusion, reducing the use of heparin, and diminishing the risk of bleeding and postoperative neurological deficits. In China, the circuit for TAAA repair is deficient, and far from the perfusion requirements. We designed a modular multifunctional LHB circuit for TAAA repair. The modular circuit consisted of cannulation pipelines, functional consumables connection pipelines, and accessory pipelines. The accessory pipelines make up lines for selective visceral perfusion and kidney perfusion, suckers and rapid infusion. The circuit can be assembled according to surgical requirements. The ultrafilter and heat exchanger are integrated into the circuit to fulfill the basic demands of LHB. The LHB circuit also has pipelines for selective visceral perfusion to the celiac artery and superior mesenteric artery and renal perfusion pipelines. Meanwhile, the reserved pipelines facilitate the quick switch from LHB to conventional cardiopulmonary bypass (CPB). The reserved pipelines reduce the time of reassembling the CPB circuit. Moreover, the rapid infusion was integrated into the LHB circuit, which can rapid infusion when massive hemorrhage during the open procedures such as exposure and reconstruction of the aorta. The ultrafiltration can diminish the consequent hemodilution of hemorrhage and rapid infusion. A hemoperfusion cartridge also can be added to reduce the systemic inflammatory during operation. The circuit can meet the needs of LHB and quickly switch to conventional CPB. No oxygenator was required during LHB, which reduce the use of heparin and reduce the risk of bleeding. The heat exchanger contributes to temperature regulation; ultrafiltration, arterial filter, and rapid-infusion facilitated the blood volume management and are useful to maintain hemodynamic stability. This circuit made the assembly of the LHB circuit more easily, and more efficient, which may contribute to the TAAA repair operation performed in lower volume centers easily. 26 patients who received TAAA repair under the modular multifunctional LHB from January 2018-March 2022 were analyzed, and we achieved acceptable clinical outcomes. The in-hospital mortality and 30-day postoperative mortality were 15.4%, and the postoperative incidences of paraparesis (4%), stroke (4%), and AKI need hemodialysis (12%) were not particularly high, based on the limited patients sample size in short research period duration.
