Abstract
OBJECTIVES Although cerebrospinal fluid drainage has been shown to reduce the risk of ischemic spinal cord injury, serious complications have also been reported. We have been using it selectively in a pressure- and volume-regulated method and aimed to evaluate its safety, and its validity in elective thoracic endovascular aortic repair in a propensity-matched cohort. METHODS Among the 450 patients who underwent open surgery (n = 169) or thoracic endovascular aortic repair (n = 281) on the descending or thoracoabdominal aorta, 147 underwent cerebrospinal fluid drainage, which was prophylactic in 135 and therapeutic in 12. Prophylactic drainage was performed in elective open surgery under distal aortic perfusion (n = 67) or in selected patients undergoing thoracic endovascular aortic repair (n = 68). RESULTS Drainage-related complications were observed in 13 (9.6%), one of which was graded severe (0.74%). In patients undergoing prophylactic drainage, spinal cord injury was detected in 2/135 (1.5%). In patients without prophylactic drainage, 15/315 (4.8%) developed spinal cord injury. Therapeutic drainage was performed in 12 of these 15 patients, 10 of whom remained paralytic in varying degree. In the inverse probability weighted analysis of the patients undergoing elective thoracic endovascular aortic repair, the incidence of spinal cord injury was lower with prophylactic drainage (p = 0.028). CONCLUSIONS Pressure- and volume-regulated spinal drainage rarely causes serious complications. Its prophylactic use seems beneficial in selected patients, including those undergoing thoracic endovascular aortic repair with high risk for spinal cord injury.

Systematic review and meta-analysis of cerebrospinal fluid drain-related mortality and morbidity after fenestrated-branched endovascular aortic repair. J Vasc Surg 2024; 80:586-594.e5. [PMID: 38636609 DOI: 10.1016/j.jvs.2024.04.038] [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: 01/11/2024] [Revised: 03/28/2024] [Accepted: 04/10/2024] [Indexed: 04/20/2024]
Abstract
OBJECTIVE This study aimed to investigate the incidence of cerebrospinal fluid drainage (CSFD)-related complications specifically in patients who underwent fenestrated and branched endovascular aortic repair (F/B-EVAR). This objective was chosen considering the limitations and uncertainties surrounding its efficacy in preventing spinal cord injury. METHODS A systematic review following Cochrane Handbook and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted (PROSPERO; #CRD42022359223). Literature searches of MEDLINE, Embase, and Scopus were performed until May 1, 2023, focusing on studies published after January 1, 2000. The inclusion criteria encompassed studies reporting on F/B-EVAR, CSFD, and drain-related complications. Data extraction and quality assessment using the Newcastle-Ottawa Scale were performed by multiple reviewers to ensure accuracy and reliability. A proportion meta-analysis was conducted to calculate the pooled rate and 95% confidence interval (CI). The primary and secondary outcomes were CSFD-related mortality and morbidity, respectively. RESULTS Six retrospective, observational, single-center studies were included, totaling 1079 patients and 730 CSFD placements (all prophylactic except for one). The Newcastle-Ottawa Scale showed a high to moderate risk of bias. The analysis revealed a CSFD-related mortality rate of 1.4% (95% CI: 0.0-4.8; I2 = 67.7%) and an overall morbidity rate of 25.6% (95% CI: 13.6-39.7; I2 = 83.2%). The overall major, moderate, and minor estimated complication rates were 6.1% (95% CI: 4.1-8.5; I2 = 0%), 4.6% (95% CI: 2.4-7.3; I2 = 33.5%), and 26.4% (95% CI: 16.5-37.7; I2 = 84.9%), respectively. Severe complications included intracranial hemorrhage (2.8%), spinal hematoma (1.4%), subarachnoid hemorrhage (1.4%), and CSFD-related neurological deficits (1.1%). A pooled estimate of 11.4% for nonfunctioning drainage was found. CONCLUSIONS F/B-EVAR patients showed a notable incidence of CSFD-related death and substantial morbidity. This study highlights the limitations of the available data, the high prevalence of complications associated with CSFD, and the need for further research to better understand the risks and benefits of CSFD in F/B-EVAR. This calls for careful consideration regarding the routine use of prophylactic drainage due to the accumulating evidence of the risks associated with CSFD without proven benefit in this specific context.

Abstract
Patients with complex aortic aneurysms (CAA) are often high risk due to advanced age and widespread atherosclerosis affecting numerous vascular territories. Therefore, a thorough perioperative evaluation is needed prior to performing in any type of aortic repair, regardless of whether an endovascular or open surgical approach is selected. Because these operations are technically demanding and often result in end organ ischemia, it is not surprising that complex aortic repair carries significant risk of morbidity and mortality. Disabling complications such as dialysis, major stroke and paraplegia constitute the main limitation of complex aortic repair. The aim of this article was to review postoperative management to mitigate complications after CAA repair.

Abstract
The advent and refinement of complex endovascular techniques in the last two decades has revolutionized the field of vascular surgery. This has allowed an effective minimally invasive treatment of extensive disease involving the pararenal and the thoracoabdominal aorta. Fenestrated-branched EVAR (F/BEVAR) now represents a feasible technical solution to address these complex diseases, moving the proximal sealing zone above the renal-visceral vessels take-off and preserving their patency. The aim of this paper was to provide a narrative review on the peri-operative management of patients undergoing F/BEVAR procedures for juxtarenal abdominal aortic aneurysm (JAAA), pararenal abdominal aortic aneurysm (PRAA) or thoracoabdominal aortic aneurism (TAAA). It will focus on how to prevent, diagnose, and manage the complications ensuing from these complex interventions, in order to improve clinical outcomes. Indeed, F/BEVAR remains a technically, physiologically, and mentally demanding procedure. Intraoperative adverse events often require prolonged or additional procedures and complications may significantly impact a patient's quality of life, health status, and overall cost of care. The presence of standardized preoperative, perioperative, and postoperative pathways of care, together with surgeons and teams with significant experience in aortic surgery, should be considered as crucial points to improve clinical outcomes. Aggressive prevention, prompt diagnosis and timely rescue of any major adverse events following the procedure remain paramount clinical needs.

Abstract
OBJECTIVE Management of antithrombotic therapy in patients undergoing elective fenestrated branched endovascular aortic repair (F-BEVAR) is not standardised, nor are there any recommendations from current guidelines. By designing an international expert based Delphi consensus, the study aimed to create recommendations on the pre-, intra-, and post-operative management of antithrombotic therapy in patients scheduled for elective F-BEVAR in high volume centres. METHODS Eight facilitators created appropriate statements regarding the study topic that were voted on, using a four point Likert scale, by a selected panel of international experts using a three round modified Delphi consensus process. Based on the experts' responses, only those statements reaching Grade A (full agreement ≥ 75%) or B (overall agreement ≥ 80% and full disagreement < 5%) were included in the final document. The round answers' consistency was graded using Cohen's k, the intraclass correlation coefficient, and, in case of double re-submission, the Fleiss k. RESULTS Sixty-seven experts were included in the final analysis and voted the initial 43 statements related to pre- (n = 15), intra- (n = 10), and post-operative (n = 18) management of antithrombotic drugs. At the end of the process, six statements (13%) were rejected, 20 statements (44%) received a Grade B consensus, and 18 statements (40%) reached a Grade A consensus. Most statements (27; 71%) exhibited very high or high consistency grades, and 11 (29%) a fair or poor grading. The intra-operative statements mostly concentrated on threshold for and monitoring of proper heparinisation. The pre- and post-operative statements mainly focused on indications for dual antiplatelet therapy and its management, considering the possible need for cerebrospinal fluid drainage. CONCLUSION Based on the elevated strength and high consistency of this international expert based Delphi consensus, most of the statements might guide current clinical management of antithrombotic therapy for elective F-BEVAR. Future studies are needed to clarify the debated issues.

Abstract
OBJECTIVE The rates of endovascular repair of thoracoabdominal aortic aneurysms (TAAA-ER) have increased considerably in the last years. While mortality and morbidity rates have improved, spinal cord ischemia (SCI) rates have not declined significantly. The aim of this systematic review and meta-analysis was to examine SCI rates with respect to the efficacy of the different approaches. METHODS Cohort studies and case series (>20 patients) reporting SCI rates after TAAA-ER were eligible for inclusion. The primary outcome was the evaluation of SCI. Moderators considered were primarily the staged/non-staged approach, the use of cerebrospinal fluid drainage (CSFD) and TAAA extension. Permanent SCI and mortality rates were extracted. RESULTS Twenty-seven studies (n=2333 patients) were included in the meta-analysis. The pooled estimate for SCI was 11% (95% confidence interval [CI]: 8%-15%; I2:80%). For extent I,II,III and V TAAA, the pooled SCI rate was 13% (95% CI: 10%-17%; I2=71%), while for extent IV TAAA it was 6% (95% CI: 3%-10%; I2=62%). A staged TAAA-ER approach was used in 18 studies and a non-staged approach in 6 (one study included both). A lower pooled SCI rate was identified following staged compared with non-staged TAAA-ER (9% vs. 18%, respectively; P=.02). Staging was accomplished in >1 month in 9 studies and ≤1 month in 2, leading to similar SCI rates (7% vs. 11%, respectively; P=.29). The method of staging (thoracic-endoprosthesis or temporary aortic sac perfusion) did not affect SCI rates. Symptomatic CSFD was associated with a similar pooled rate of SCI compared with prophylactic CSFD (10% vs. 10%, respectively; P=.95). Pooled permanent SCI was 5% (6% following extent I,II,III and V TAAA; 3% following extent IV TAAA). Prophylactic or symptomatic CSFD have a similar rate of SCI (10% vs. 10%, respectively; P=.89). The pooled rate of 30-day mortality was 7%, with a similar incidence for the staged and non-staged approaches (6% vs. 9%, respectively). The inter-stage mortality was reported in 10 studies, with a pooled estimate rate of 1.6%. CONCLUSIONS SCI occurs in 11% of TAAA-ER and half of these cases are permanent. A staged approach can reduce SCI rates independently from the timing and the method adopted. The overall mortality rate for staged TAAA-ER is 6%, with one fourth of deaths (1.6%) occurring between stages.

Platelet Depletion after Thoraco-Abdominal Aortic Aneurysm Endovascular Repair is Associated with Clinically Relevant Hemorrhagic Complications. Ann Vasc Surg 2021; 79:106-113. [PMID: 34688873 DOI: 10.1016/j.avsg.2021.08.036] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 07/29/2021] [Accepted: 08/05/2021] [Indexed: 01/29/2023]
Abstract
BACKGROUND Thoraco-abdominal endovascular aortic repair (TA-EVAR) can be associated with platelet depletion (PD); the present study aims to evaluate PD incidence after TA-EVAR and to investigate its possible predictors and its influence on hemorrhagic complications and mortality. METHODS A retrospective analysis of all TA-EVAR from 2010 to 2021 was performed to identify patients with PD, (reduction > 60%). Spontaneous hemorrhages considered were: intracranial or any hemorrhages requiring surgery. Risk factors for PD, correlation with hemorrhagic complications and 30-day mortality were investigated by uni/multivariate analysis. RESULTS A total of 158 TA-EVAR were considered, 35(22%) female, 86(54%) extended thoraco-abdominal aortic aneurysm (TAAA) (Crawford type I, II, III), 79(50%) staged procedure, 31(20%) urgent treatment (symptomatic/ruptured). PD was identified in 42 (27%) patients and correlated to female sex, thrombus-free aortic lumen > 50mm, urgent treatment, extensive TAAA, blood transfusion >3 units and staged procedure at the univariate analysis. The multivariate analysis confirmed a significant correlation between PD and thrombus-free aortic lumen > 50mm, urgent treatment, blood transfusion > 3 units and staged procedure (odds ratio [OR]: 2.5 (95% confidence interval [CI] 1.03-7.0), P = 0.04, OR 3.2 (95% CI 1.01-8.6), P= 0.03, OR 3.16 (95% CI 1.23-7.7), P = 0.03 and OR 2.71 (95% CI 1.2-6.2), P= 0.04, respectively). Overall, 13 hemorrhagic complications occurred (8 intracranial and 5 peripheral); PD was associated with higher risk of hemorrhagic complications (9/42 - 21% vs. 4/116 - 3%, OR: 7.6 [95% CI: 2.2-26.3], P= 0.001) and a higher risk of 30-day mortality in elective cases 4/25 - 16% vs. 3/101 - 3%, OR: 6.2 (95% CI: 1.3-29.8), P= 0.03. CONCLUSIONS PD is a relatively common event after TA-EVAR and is associated with thrombus-free aortic lumen > 50mm, urgent treatment, blood transfusion > 3 units and staged procedure. Hemorrhagic complications and mortality are increased under these circumstances.
