Intra- and Early Post-Operative Factors Affecting Spinal Cord Ischemia in Patients Undergoing Fenestrated and Branched Endovascular Aortic Repair. J Clin Med 2024; 13:3978. [PMID: 38999542 PMCID: PMC11242175 DOI: 10.3390/jcm13133978] [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: 06/11/2024] [Revised: 06/27/2024] [Accepted: 07/05/2024] [Indexed: 07/14/2024] Open
Abstract
Background: Spinal cord ischemia (SCI) is a severe complication after fenestrated/branched endovascular repair (f/bEVAR). The underlying causes of SCI are still under investigation. This study aimed to evaluate intra- and early post-operative parameters that may affect SCI evolution. Methods: A single-center retrospective analysis was conducted including SCI patients with complete anesthesiologic records (1 January 2011 to 31 December 2023). Values of intra-operative glucose, hemoglobin, lactate, activated clotting time (ACT), and the need for transfusion were collected. The cohort was compared to a matched cohort of non-SCI patients. Results: Fifty-one patients with SCI and complete anesthesiologic records were included (mean age: 69.8 ± 6.2 years; 39.2% male). Intra-operative glucose value < 110 mg/dL (AUC: 0.73; sensitivity 91%, specificity of 83%) and hemoglobin value > 8.5 mg/dL (AUC: 0.61; sensitivity 83%, specificity 78%) were protective for Grade 3 SCI. Twenty-three patients with SCI were matched to 23 patients without SCI. SCI patients presented significantly higher glucose levels intra-operatively (glucose mean value: SCI 150 ± 46 mg/dL vs. non-SCI: 122 ± 30 mg/dL, p = 0.005). ACT (SCI 259 ± 31 svs. non-SCI 288 ± 28 s, p = 0.001), volume input (SCI 4030 ± 1430 mL vs. non-SCI 3020 ± 113 mL, p = 0.009), and need for transfusion (SCI: 52.5% vs. 4.3%, p < 0.001) were related to SCI. Higher glucose levels were detected among patients with SCI, at 24 (SCI: 142 ± 30 mg/dL vs. non-SCI: 118 ± 26 mg/dL, p=0.004) and 48 h (SCI: 140 ± 29 mg/dL vs. non-SCI: 112 ± 20 mg/dL, p < 0.001) post-operatively. Conclusions: SCI is a multifactorial complication after f/bEVAR. Intra-operative and early post-operative glucose levels may be related to SCI evolution. Targeted glucose < 110 mg/dL may be protective for Grade 3 SCI.

Abstract
OBJECTIVE Paraplegia is one of the most feared complications after thoracoabdominal aortic aneurysm repair. The purpose of this study is to determine whether aortic thrombus characteristics are associated with spinal cord ischemia (SCI) after branched endovascular aneurysm repair (BEVAR). METHODS From April 2011 to April 2020, 62 patients underwent elective BEVAR for thoracoabdominal aortic aneurysm and pararenal aortic aneurysms using a low-profile device and had a complete preoperative computed tomography angiography of the aorta from the sinotubular junction to the aortic bifurcation. Aortic thrombus was evaluated for thrombus thickness ≥5 mm, thrombus >2/3 of aortic circumference, and the presence of an ulcer-like thrombus. One point was assigned at each 5 mm axial image if all 3 criteria were met, resulting in a total "shaggy score" for the entire aorta. Data on demographics, procedural details, and outcomes were collected prospectively. All patients underwent a standard spinal cord protection protocol, including routine cerebrospinal fluid drainage. In July 2016, an insulin infusion protocol (IIP) was initiated to maintain postoperative blood glucose levels <120 mg/dL for 48 hours. The primary clinical end point was postoperative SCI. RESULTS 10 (16%) patients developed postoperative SCI: 6 with transient paraparesis, 2 with persistent paraparesis, and 2 with persistent paraplegia. Patients with SCI were older, had higher shaggy scores, and were less likely to have been on an IIP. There were no significant differences in demographics, aneurysm type, or operative parameters. In a logistic multivariate regression model for SCI, age (odds ratio [OR]: 1.2 [1.1-1.4], P = .02) and shaggy score (OR: 1.2 [1.1-1.4], P = .02) were independently associated with increased risk of SCI, whereas treatment with the IIP was associated with lower risk of SCI (OR: 0.04 [0.006-0.50], P = .05). Of the individual components of the shaggy score, higher descending thoracic aortic ulcer scores were the most strongly associated with postoperative SCI (P = .009). CONCLUSIONS Preoperative characterization of aortic wall thrombus is an important adjunctive tool for individualized clinical decision-making and patient counseling about the risk of SCI after BEVAR.

Abstract
Complex endovascular aortic repair (coEVAR) of thoracoabdominal aortic aneurysms (TAAA) has greatly evolved in the past decades. Despite substantial improvements of postoperative care, spinal cord injury (SCI) remains the most devastating complication of coEVAR being associated with impaired patient outcome and having an impact on long-term survival. The rising number of challenges of coEVAR, essentially associated with an extensive coverage of critical blood vessels supplying the spinal cord, resulted in the implementation of dedicated SCI prevention protocols. In addition to maintenance of adequate spinal cord perfusion pressure (SCPP), early detection of SCI plays an integral role in intra- and postoperative patient care. However, this is challenging due to difficulties with clinical neurological examinations during patient sedation in the postoperative setting. There is a rising amount of evidence, suggesting that subclinical forms of SCI might be accompanied by an elevation of biochemical markers, specific to neuronal tissue damage. Addressing this hypothesis, several studies have attempted to assess the potential of selected biomarkers with regard to early SCI diagnosis. In this review, we discuss biomarkers measured in patients undergoing coEVAR. Once validated in future prospective clinical studies, biomarkers of neuronal tissue damage may potentially add to the armamentarium of modalities for early SCI diagnosis and risk stratification.

Abstract
OBJECTIVE We conducted a systemic review and meta-analysis to compare the association between prophylactic cerebrospinal fluid drainage (CSFD) vs non-CSFD in preventing spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) for aneurysm and dissection. METHODS The MEDLINE, Embase, and Cochrane databases were systematically searched to identify all relevant studies reported before April 1, 2020. A systematic review and meta-analysis were performed. We assessed the association between CSFD strategies, including routine CSFD vs selective CSFD or no CSFD, and the SCI rates after TEVAR for patients with aortic dissection (AD), solitary thoracic aortic aneurysm (TAA), or thoracoabdominal aortic aneurysm (TAAA). Subgroup analyses were conducted to assess the association between different aortic pathologies, including AD and thoracic aneurysms, and SCI rates after TEVAR with and without prophylactic CSFD. The data are presented as the pooled event rates (ERs) and 95% confidence intervals (CIs). RESULTS A total of 34 studies of 3561 patients (2671 with TAA or TAAA and 890 with type B AD) were included in the present analysis. The data are presented as the pooled ERs and 95% CIs. The overall SCI rate for patients who had undergone TEVAR with prophylactic CSFD for AD (ER, 1.80%; 95% CI, 0.88%-2.72%) was significantly lower than that for the aortic aneurysm group (ER, 5.73%; 95% CI, 4.20%-7.27%; P < .0001). The SCI rate after TEVAR with prophylactic CSFD was not significantly different from that without CSFD for AD (P = .51). No association was found between the rates of SCI after TEVAR with routine prophylactic CSFD vs selective prophylactic CSFD for aortic aneurysms (P = .76) and AD (P = .70). The SCI rate after TEVAR without CSFD for aortic aneurysms, including isolated TAA and TAAA (ER, 3.49%; 95% CI, 0.23%-6.76%) was not significantly different from that for AD (ER, 3.20%; 95% CI, 0.00%-7.20%; P = .91). For the patients with TAAAs, the rate of SCI after TEVAR with routine prophylactic CSFD was significantly lower than that with selective prophylactic CSFD (P = .04). CONCLUSIONS Our systematic review and meta-analysis has shown that SCI occurs more often after TEVAR for aortic aneurysms than for AD. Routine prophylactic CSFD, compared with selective CSFD, was associated with a lower rate of postoperative SCI after TEVAR for TAAAs. No significant association was found between the SCI rate and routine prophylactic CSFD for patients undergoing TEVAR for isolated TAA or AD.

Abstract
OBJECTIVE Spinal cord ischemia (SCI) is one of the most devastating complications after descending thoracic aortic (DTA) and thoracoabdominal aortic (TAA) repairs. Patients who develop SCI have a poor prognosis with mortality rates reaching 75% within the first year after surgery. Many factors have been shown to increase the risk of this complication, including extent of TAA repair, length of aortic and collateral network coverage, embolization, and reduced spinal cord perfusion pressure. As a result, a variety of treatment strategies have evolved. We aimed to provide an up-to-date review of SCI rates with associated treatment algorithms from open and endovascular DTA and TAA repairs. METHODS Using PRISMA guidelines, a literature review with the Medical Subject Headings (MeSH) terms "spinal cord ischemia; spinal cord ischemia prevention and mitigation strategies; spinal cord ischemia rates; spinal cord infarction" was performed in the Cochrane and PubMed databases to seek all peer-reviewed studies of DTA and TAA repairs with SCI complications, limited to 2012-2021 and the English language. MeSH subheadings including diagnosis, complications, physiopathology, surgery, mortality, and therapy were used to further restrict the articles. Studies were excluded if they were not in humans, not pertaining to SCI in DTA/TAA operative repairs, and if the study primarily discussed neuromonitoring techniques. Additionally, studies with <40 patients or limited information regarding SCI protection strategies were excluded. Each study was individually reviewed by two researchers to assess for type and extent of aortic pathology, operative technique, SCI protection or mitigation strategies, rates of overall and permanent SCI symptoms, associations with SCI on multivariate analysis, and mortality. RESULTS Of 450 studies returned by the MeSH search strategy, 41 met inclusion criteria and were included in the final analysis. For endovascular DTA repair patients, overall SCI rates ranged from 0-10.6% with permanent SCI symptoms ranging from 0-5.1%. Endovascular and open TAA repairs had rates of overall SCI of 0-35%. Permanent SCI symptom rate was reported by only one open study at 1.1% while endovascular TAA repairs had between 2-20.5%. CONCLUSION This review provides an up-to-date review of current rates of SCI as well as prevention and mitigation strategies for DTA and TAA repairs. We find that a multimodal approach, including a bundled institutional protocol, staging of multiple repairs, preservation of collateral blood flow network, augmented spinal cord perfusion, selective cerebrospinal fluid drainage, and distal aortic perfusion in open TAA repairs, appears to be important in reducing the risk of SCI.

Abstract
OBJECTIVE This study aimed to explore the correlation of elevated glucose levels in the blood and cerebrospinal fluid with the progression and short-term prognosis of Guillain-Barré syndrome (GBS). METHODS The medical records of 982 patients who were diagnosed with GBS in 31 representative tertiary hospitals, located in 14 provinces in southern China, were collected and retrospectively reviewed. Patients were grouped according to the levels of fasting plasma glucose (FPG) and cerebrospinal fluid (CSF) glucose, as well as the concentration of blood hemoglobinAlc (HbA1c). The Hughes grade scale was used to quantify functional outcomes. RESULTS Compared to patients with normal FPG and CSF glucose levels, those in the high FPG and high CSF glucose groups were characterized by a higher proportion of severe patients (HFGS ≥ 3) at admission (58.8 vs. 73.1, P = 0.000; 57.6 vs. 71.2, P = 0.000), at nadir (67.4 vs. 83.0, P = 0.000; 66.2 vs. 80.4, P = 0.000), and at discharge (29.8 vs. 46.3, P = 0.000; 26.4 vs. 45.0, P = 0.000). Patients in the high HbA1c group also had more severe disability at admission (74.6 vs. 56.1, P = 0.005) and at nadir (80.3 vs. 64.3, P = 0.012) compared to the normal HbA1c group. Moreover, elevated levels of FPG and CSF glucose were significantly correlated with more severe disability at admission, at nadir, and at discharge. CONCLUSIONS The present study showed that elevated glucose levels in the blood and cerebrospinal fluid were associated with the severity and short-term prognosis of GBS.

Abstract
OBJECTIVES To describe contemporary outcomes from a single center capable of both complex open and endovascular aortic repair for paravisceral aortic aneurysms (PVAAA). METHODS Data on all patients receiving open or endovascular (endo) treatment for aortic aneurysms with proximal extent at or above the renal arteries and distal to the inferior pulmonary ligament (IPL) were reviewed. Coarsened exact matching (CEM) on age, aneurysm type, gender, coronary artery disease (CAD), previous aortic surgery and symptomatic status created balanced cohorts for outcomes comparisons. RESULTS Between October, 2006 and February, 2018, 194 patients were treated for juxtarenal (40%), pararenal (21%), paravisceral (6%) and Type 4 thoracoabdominal (34%) aortic aneurysms with open (81, 42%) or endo (113, 58%) at a single tertiary center. Endo repairs included renal coverage with a bifurcated graft (2%), unilateral (13%) or bilateral (4%) renal snorkels, Z-fen (15%), multi-branched graft (IDE protocol; 62%) and unique complex configurations (4%). On multivariable analysis, patients selected for open surgery were more likely to be symptomatic, whereas older patients, female patients and those with Type 4 TAAA extent were more often selected for endovascular treatment. Matching based on the significant independent covariates reduced the open and endovascular groups by one-third. Survival at 30 days was 97% for endo and 94% for open repair, 98% for both subgroups when excluding symptomatic cases, and was not different between the matched groups (98% vs 89%; P=0.23). Hospital and ICU stays were longer in open patients (8 vs. 10 days, 2 vs. 4, both P≤0.001). Post-op CVA, MI, lower extremity ischemia, surgical site infections and reoperation were not different between matched groups (all p>0.05), while pulmonary and intestinal complications, as well as grade 1/2 renal dysfunction by RIFLE criteria, were more common after open repair (all P<0.05). Spinal cord ischemia was significantly more frequent in the unmatched Endo group (11% vs. 1%, P=0.02), but this difference was not significant after matching. Composite major aortic complications was no different between treatment groups (unmatched P=0.91, matched P=0.87). Endo treatment resulted in patients more frequently discharged to home (84% vs. 66%, P=0.02). Reintervention after 30 days occurred more frequently in the endo group (P=0.002). Estimated survivals at 1 and 5 years for endo and open are 96% vs. 81% and 69% vs. 81% respectively (Log-rank P=0.57). CONCLUSIONS Contemporary repair of PVAAA demonstrates safe outcomes with durable survival benefit when patients are well-selected for open or complex endovascular repair. We believe these data have implications for off-label device use in the treatment of PVAAA, and that open repair remains an essential option for younger, good risk patients in experienced centers.

Abstract
Spinal cord ischemia (SCI) is a clinical complication following aortic repair that significantly impairs the quality and expectancy of life. Despite some strategies, like cerebrospinal fluid drainage, the occurrence of neurological symptoms, such as paraplegia and paraparesis, remains unpredictable. Beside the major blood supply through conduit arteries, a huge collateral network protects the central nervous system from ischemia—the paraspinous and the intraspinal compartment. The intraspinal arcades maintain perfusion pressure following a sudden inflow interruption, whereas the paraspinal system first needs to undergo arteriogenesis to ensure sufficient blood supply after an acute ischemic insult. The so-called steal phenomenon can even worsen the postoperative situation by causing the hypoperfusion of the spine when, shortly after thoracoabdominal aortic aneurysm (TAAA) surgery, muscles connected with the network divert blood and cause additional stress. Vessels are a conglomeration of different cell types involved in adapting to stress, like endothelial cells, smooth muscle cells, and pericytes. This adaption to stress is subdivided in three phases—initiation, growth, and the maturation phase. In fields of endovascular aortic aneurysm repair, pre-operative selective segmental artery occlusion may enable the development of a sufficient collateral network by stimulating collateral vessel growth, which, again, may prevent spinal cord ischemia. Among others, the major signaling pathways include the phosphoinositide 3 kinase (PI3K) pathway/the antiapoptotic kinase (AKT) pathway/the endothelial nitric oxide synthase (eNOS) pathway, the Erk1, the delta-like ligand (DII), the jagged (Jag)/NOTCH pathway, and the midkine regulatory cytokine signaling pathways.

Abstract
BACKGROUND Abnormalities in glucose metabolism are common in patients with arterial disease. Chronic hyperglycemia and insulin resistance contribute to the complexity of vascular disorders. They also overlap with the effects of perioperative hyperglycemia on adverse perioperative outcomes. We provide an overview of the pathophysiologic consequences of dysglycemia and the evidence behind glycemic control in patients undergoing vascular surgery. METHODS We searched the literature for major studies evaluating the pathophysiology of hyperglycemia in microvascular and macrovascular beds, randomized trials in perioperative populations, and meta-analyses. The literature was summarized to guide therapy in the population of vascular patients and for the perioperative period. RESULTS National standards for glycemic control after vascular interventions were not identified. Mounting evidence exists for the long-term consequences of poor glycemic control on the progression of vascular disease. Similarly, there is a large body of evidence supporting tight control of hyperglycemia after general and cardiac surgery during the critical perioperative period. The absolute glucose target remains controversial. Randomized controlled studies are lacking in vascular surgery patients, but the current evidence can be extrapolated to guide management after vascular interventions. Glycated hemoglobin is a biomarker for increased mortality and vascular morbidity after vascular surgery. CONCLUSIONS Hyperglycemia contributes to poor outcome in the vascular patient. Further vascular focused studies are required to determine the proper perioperative serum glucose target and the long-term glycated hemoglobin range.

Abstract
Even though diabetes mellitus is a major risk for cardiovascular events and atherosclerosis-related diseases, it is negatively associated with abdominal aortic aneurysm. The understanding of the mechanisms underlying this negative association could bring new insights to identify prognostic and therapeutic targets. Here we summarize current knowledge of the relationship between glycemic parameters and clinical outcomes of patients with abdominal aortic aneurysm. Translational applications of glucose-targeted approaches as well as their potential interest for clinical practice are discussed in this context.

Abstract
The recent recognition that Alzheimer disease-like pathology may be found in chronic traumatic encephalopathy (CTE) even after acute mild traumatic brain injury (mTBI) has increased the urgency of elucidating mechanisms, identifying biomarkers predictive of high risk of development of CTE, and establishing biomarker profiles indicative of impactful effects of treatments. Of the many proteins that are loaded into neuron-derived exosomes (NDEs) from damaged neurons after acute TBI, the levels of prion cellular protein (PRPc), coagulation factor XIII (XIIIa), synaptogyrin-3, IL-6, and aquaporins remain elevated for months. Prolonged heightened expression of aquaporins and IL-6 may account for the persistent central nervous system edema and inflammation of CTE. PRPc, XIIIa and synaptogyrin-3 bind and concentrate neurotoxic forms of oligomeric amyloid β peptides or P-tau for delivery into neurons at or distant from the site of trauma. Our progression factor hypothesis of CTE asserts that physiological neuronal proteins, such as PRPc, XIIIa, synaptogyrin-3, IL-6 and aquaporins, that increase in concentration in neurons and NDEs for months after acute TBI, are etiological contributors to CTE by either direct actions or by recruiting neurotoxic forms of Aβ peptides or P-tau. Such progression factors also may be useful new targets for development of drugs to prevent CTE.

Abstract
Introduction: Despite advances in perioperative critical care and surgical technique, spinal cord ischemia remains a devastating complication of thoracic and thoracoabdominal aortic aneurysm repair. Biochemical markers present in peripheral blood and cerebrospinal fluid (CSF) may be useful in assessing spinal cord injury. We systematically analyze and report the role of all reported biochemical markers that have been used in assessing and diagnosing spinal cord ischemia in thoracic and thoracoabdominal aortic aneurysm repair. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used for this review. Published literature was searched to identify all studies reporting on the use of biochemical markers in thoracoabdominal aortic aneurysm repair in the assessment of spinal cord ischemia. Marker-specific and patient-specific data were extracted from all studies and where possible, subgroup analysis was performed on marker-specific data sets. Results: Fourteen studies of 321 patients undergoing thoracic and thoracoabdominal aortic aneurysm repair were eligible for further analysis. Seven distinct biochemical markers were used in both CSF and blood samples: S100B proteins (S100B), neurone-specific enolase, lactate dehydrogenase, glial fibrillary acidic protein (GFAp), neurofilament triplet protein (NFL) and Tau protein, and glucose. There was substantial evidence demonstrating the heightened levels of S100, NFL, and GFAp in CSF in patients with spinal cord ischemia. There is however, wide variability in the correlation of the same 6 biochemical markers in peripheral blood and spinal cord ischemia. Conclusions: In patients with spinal cord injury, dramatic rises occur with S100B, NFL, and GFAp in CSF. However, further work is needed if biochemical markers are to impact on the future of thoracoabdominal aortic aneurysm repair.
