ABSTRACT
Measles is the most contagious communicable disease, causing an estimated 5.5 million cases and more than 30,000 deaths in the Western Pacific Region (WPR) during 2000. Rubella infection in a pregnant woman can be devastating for the foetus, resulting in congenital rubella syndrome (CRS) in 90% of rubella infections in early pregnancy. It was estimated that approximately 9000 CRS cases occurred in the WPR in 2010. World Health Organization (WHO) Member States in the WPR decided in 2003 to eliminate measles and in 2014 to eliminate rubella from the region. While the WPR successfully attained historically low measles incidence in 2012, it experienced a region-wide measles resurgence in 2013-2016. During the regional resurgence, WHO and Member States accumulated greater knowledge on the epidemiology of measles and rubella in the WPR and strategies to maintain gains. The implementation of the resulting new regional strategy and plan of action from 2018 has proven that measles and rubella elimination is achievable and sustainable under the pressure of multiple importations of measles virus during the world-wide measles resurgences in 2018-2019. This article discusses this progress and achievements towards achieving the global eradication of measles and rubella.
ABSTRACT
The Western Pacific Region's pursuit of measles elimination has seen significant progress and setbacks. Mongolia and Cambodia were the first two middle-income countries in the Western Pacific to be verified as having eliminated measles by the Western Pacific Regional Verification Commission for Measles and Rubella Elimination, in March 2014 and 2015, respectively. However, both countries experienced large-scale or prolonged importation-related measles outbreaks shortly afterwards, leading to the re-establishment of endemic transmission. We describe the path to initial elimination in both countries and explore these outbreaks' characteristics, factors contributing to the loss of elimination status, and implications for broader elimination efforts. Data sources include case-based epidemiological and laboratory surveillance reports, historical immunization coverage, genotype data, and published reports of in-depth outbreak investigations. In Mongolia, a single prolonged and large-scale outbreak revealed a hidden immunity gap among young adults and was driven in part by nosocomial transmission, leading to significant morbidity and mortality and loss of elimination status. Cambodia suffered multiple importations from neighboring endemic countries during the global measles resurgence in 2018-2019, complicated by cross-border mobility and significant nosocomial amplification, and the country was ultimately unable to sufficiently distinguish independent chains of transmission, leading to loss of elimination status. Our findings highlight the importance of broadening population immunity assessments beyond children to include adults and specific high-risk groups. Robust routine immunization programs, supplemented by tailored SIAs, are crucial for preventing and managing outbreaks. Additionally, strong outbreak preparedness plans, rapid response strategies, and cross-border collaboration and the global effort to prevent multiple resurgences and large-scale importation-induced outbreaks are vital for maintaining elimination status. The experiences of Mongolia and Cambodia underscore the challenges of sustaining measles elimination in the face of importation risks, shared borders with endemic countries, healthcare system gaps, and population movements. Strengthening the global coordination and synchronization of measles elimination activities is imperative to protect the gains achieved and prevent future setbacks.
ABSTRACT
BACKGROUND: Ruptured abdominal aortic aneurysms (rAAAs) are a serious disease that can lead to high mortality; thus, their early prediction can save patients' lives. The aim of this study was to compare the accuracies of various models for predicting rAAA mortality-including the Glasgow Aneurysm Score, Vancouver Scoring System, Dutch Aneurysm Score, Edinburgh Ruptured Aneurysm Score (ERAS), and Hardman index-based on rAAA treatment outcomes at our institution. METHODS: Between 2016 and 2022, we retrospectively analyzed the early outcome data-including 30-day mortality-of patients who underwent emergency surgery for rAAA at our institution. Receiver operating characteristic curve analysis was performed to compare the aneurysm scoring systems for mortality using the area under the receiver operating characteristic curve (AUC). RESULTS: The AUC was better for the ERAS (0.718; 95% confidence interval, 0.601-0.817) than for the other scoring systems. Significant differences were observed between ERAS and Hardman indices (difference: 0.179; P = 0.016). No significant differences were found among the Glasgow Aneurysm Score, Vancouver Scoring System, and Dutch Aneurysm Score predictive risk models. CONCLUSIONS: Among the models for predicting mortality in patients with rAAA, the ERAS model demonstrated the highest AUC value; however, significant differences were only observed between ERAS and Hardman indices. This study may help develop strategies for improving rAAA prediction.
ABSTRACT
Transient electronics technology has enabled the programmed disintegration of functional devices, paving the way for environmentally sustainable management of electronic wastes as well as facilitating the exploration of novel device concepts. While a variety of inorganic and/or organic materials have been employed as media to introduce transient characteristics in electronic devices, they have been mainly limited to function as passive device components. Herein, we report that calcium (Ca) alginate, a natural biopolymer, exhibits multifunctionalities of introducing light-triggered transient characteristics as well as constituting active components in electronic devices integrated with two-dimensional (2D) molybdenum disulfide (MoS2) layers. Ca2+ ions-based alginate electrolyte films are prepared through hydrolysis reactions and are subsequently incorporated with riboflavin, a natural photosensitizer, for the light-driven dissolution of 2D MoS2 layers. The alginate films exhibit strain-sensitive triboelectricity, confirming the presence of abundant mobile Ca2+ ions, which enables them to be active components of 2D MoS2 field-effect transistors (FETs) functioning as electrolyte top-gates. The alginate-integrated 2D MoS2 FETs display intriguing transient characteristics of spontaneous degradation upon ultraviolet-to-visible light illumination as well as water exposure. Such transient characteristics are demonstrated even in ambient conditions with natural sunlight, highlighting the versatility of the developed approach. This study emphasizes a relatively unexplored aspect of combining naturally abundant polymers with emerging near atom-thickness semiconductors toward realizing unconventional and transformative device functionalities.
ABSTRACT
Prevailing over the bottleneck of von Neumann computing has been significant attention due to the inevitableness of proceeding through enormous data volumes in current digital technologies. Inspired by the human brain's operational principle, the artificial synapse of neuromorphic computing has been explored as an emerging solution. Especially, the optoelectronic synapse is of growing interest as vision is an essential source of information in which dealing with optical stimuli is vital. Herein, flexible optoelectronic synaptic devices composed of centimeter-scale tellurium dioxide (TeO2) films detecting and exhibiting synaptic characteristics to broadband wavelengths are presented. The TeO2-based flexible devices demonstrate a comprehensive set of emulating basic optoelectronic synaptic characteristics; i.e., excitatory postsynaptic current (EPSC), paired-pulse facilitation (PPF), conversion of short-term to long-term memory, and learning/forgetting. Furthermore, they feature linear and symmetric conductance synaptic weight updates at various wavelengths, which are applicable to broadband neuromorphic computations. Based on this large set of synaptic attributes, a variety of applications such as logistic functions or deep learning and image recognition as well as learning simulations are demonstrated. This work proposes a significant milestone of wafer-scale metal oxide semiconductor-based artificial synapses solely utilizing their optoelectronic features and mechanical flexibility, which is attractive toward scaled-up neuromorphic architectures.
ABSTRACT
BACKGROUND: Considering a patient's anatomy and vascular conditions, aorto-femoral bypass is a treatment approach for the open repair of abdominal aortic aneurysms. This study aimed at evaluating changes in the remnant iliac artery and their correlation with the preservation state of retrograde flow from femoral anastomosis. METHODS: Of 221 patients who underwent abdominal aortic aneurysm surgery between 2007 and 2022 in Pusan National University Hospital, 29 patients who underwent aorto-femoral bypass were included in this retrospective cohort study. Of these patients, 21 underwent aortobifemoral bypass and 8 underwent aortoiliac-and-femoral bypass. The change in size of the iliac artery from preoperative to postoperative and whether this difference in size depended on the status of postoperative retrograde flow were investigated. Additionally, factors affecting overall mortality and ischemic complications were identified. RESULTS: The median duration from operation to the last follow-up was 2069.5 days (about 5.7 years). The average age of the patients was 78.1 years, and the proportion of males was 75.9%. In cases of disappearance of postoperative retrograde flow from the femoral anastomosis, the postoperative iliac artery size was significantly reduced compared to its preoperative size (18.4 ± 18.9 mm vs. 13.2 ± 7.9 mm, respectively; P = 0.04). The group with maintained retrograde flow had significantly larger residual common iliac artery size than the group with disappearance of flow. (20.0 ± 28.0 mm vs. 14.6 ± 8.5 mm, respectively; P = 0.02). Disappearance of retrograde flow was a significant factor in the iliac artery size reduction after surgery (odds ratio, 2.5; 95% confidence interval, 1.9-5.3; P = 0.02). Three patients with maintained retrograde flow (18.8%) required intervention owing to an increase in the size of the iliac artery. The factors that significantly influenced overall death as analyzed by Cox proportional hazard regression were chronic obstructive pulmonary disease (hazard ratio, 36.8; 95% confidence interval, 1.6-870.0; P = 0.03), peripheral arterial occlusive disease (hazard ratio, 12.7; 95% confidence interval, 1.4-115.8; P = 0.02), and disappearance of retrograde flow (hazard ratio, 8.7; 95% confidence interval, 1.2-63.9; P = 0.03). CONCLUSIONS: Among the open repair methods for abdominal aortic aneurysms, if retrograde flow was not maintained through femoral anastomosis when aorto-femoral bypass was performed, the size of the remaining iliac artery decreased. However, loss of retrograde flow increased long-term mortality. When aorto-femoral bypass is performed, regular imaging follow-up is necessary at appropriate intervals to check the remnant iliac artery and retrograde flow.

PURPOSE: To evaluate the efficacy of staged full-length balloon-assisted maturation (BAM) for the maturation of arteriovenous fistulas (AVFs) on entire segmental veins, including stenosis, causing primary AVF failure. METHODS: This study included patients who underwent AVF surgery using an autogenous vein between February 2020 and June 2021 and received staged angioplasty with a full-length balloon catheter. To minimize balloon overlap and the risk of barotrauma to the immature vein, serial-staged upsizing balloon angioplasty with a long balloon catheter covering the entire vein segment was employed approximately 2 weeks apart. RESULTS: Twenty-three patients (mean age, 69.50 years; mean follow-up, 620.62 days) with average diameters of the radial artery and cephalic vein at 2.14 ± 0.5 mm and 2.43 ± 0.5 mm, respectively, were enrolled. In the first procedure, the average AVF diameter and flow were 4.03 ± 0.57 mm and 438.08 ± 220.95 mL/min, respectively, with juxta-anastomotic stenosis (JAS) present in 61.5% of cases. After staged full-length BAM, the average fistula diameter and flow improved to 5.95 ± 0.86 mm and 717.52 ± 305.95 mL/min, respectively. Maturation was achieved in 87% of the cases. No hematomas or ruptures occurred around the arterialized veins. Despite successful maturation and cannulation, 65.2% of the patients required additional percutaneous transluminal angioplasty (PTA) during the follow-up period. The necessity for PTA was determined by the presence of JAS prior to the first staged full-length BAM, with an odds ratio of 11.74 (95% confidence interval: 1.31-104.96, P = 0.03). CONCLUSION: Staged full-length BAM can be safely used in patients with small veins requiring further maturation. Most patients achieved successful cannulation following maturation without post-procedural complications. CLINICAL SIGNIFICANCE: Staged full-length BAM is a safe and effective method for enhancing maturation in patients with underdeveloped small veins.
ABSTRACT
We analyzed chemoport insertion procedures to evaluate infectious morbidity and factors causing infection. This single-center retrospective study included 1690 cases of chemoport implantation between January 2017 and December 2020. Overall, chemoports were inserted in 1582 patients. The average duration of chemoport use was 481 days (range 1-1794, median 309). Infections occurred in 80 cases (4.7%), with 0.098 per 1000 catheter-days. Among the 80 cases in which chemoports were removed because of suspected infection, bacteria were identified in 48 (60%). Significantly more cases of left internal jugular vein punctures were noted in the infected group (15 [18.8%] vs. 147 [9.1%]; p = 0.004). Pulmonary embolism was significantly different between the infection groups (3 [3.8%] vs. 19 (1.2%), p = 0.048). The hazard ratio was 2.259 (95% confidence interval [CI] 1.288-3.962) for the left internal jugular vein, 3.393 (95% CI 1.069-10.765) for pulmonary embolism, and 0.488 (95% CI 0.244-0.977) for chronic obstructive pulmonary disease. Using the right internal jugular vein rather than the left internal jugular vein when performing chemoport insertion might reduce subsequent infections.

BACKGROUND: To evaluate the efficacy of rejoining mainstream and accessory veins for forced maturation of autogenous arteriovenous fistula (AVF). METHODS: Twenty-three patients who underwent forced maturation through vein rejoining between January 2018 and September 2022 were included. In cases where AVF maturation failure due to the presence of accessory veins, rejoining was primarily considered when distinguishing the main branch becomes challenging. This difficulty typically occurs when the sizes of the 2 vessels are nearly equal and the combined diameters of these veins exceed 6 mm. RESULTS: The mean age and follow-up duration were 57.39 ± 16.22 years and 965.65 ± 573.42 days, respectively. Rejoining of both arterial and venous cannulation sites was performed in 11 patients (47.8%), and rejoining of only the venous cannulation site or only the arterial cannulation site was performed in 11 patients (47.8%) and 1 patient (4.3%), respectively. The mean vein size was 0.35 ± 0.06 cm before rejoining and 0.69 ± 0.07 cm after surgery, indicating a significant increase in size (P < 0.01), whereas the flow did not change significantly following rejoining surgery. Maturation and cannulation success was 100%. The 1-year primary patency rate after surgery was 82.0%. During the follow-up period, 34.8% of the patients required additional percutaneous transluminal angioplasty to maintain patency, and 2 patients (11.8%) had stenosis in the rejoined section. CONCLUSIONS: Rejoining surgery is an effective method for achieving AVF maturation in patients with accessory veins when identification of the mainstream vein is difficult, and this method may be considered when achieving maturation by sacrificing 1 vein is expected to be challenging.

Vascular diseases, such as abdominal aortic aneurysms, are associated with tissue degeneration of the aortic wall, resulting in variations in mechanical properties, such as tissue ultimate stress and a high slope. Variations in the mechanical properties of tissues may be associated with an increase in the number of collagen cross-links. Understanding the effect of collagen cross-linking on tissue mechanical properties can significantly aid in predicting diseased aortic tissue rupture and improve the clarity of decisions regarding surgical procedures. Therefore, this study focused on increasing the density of the aortic tissue through cross-linking and investigating the mechanical properties of the thoracic aortic tissue in relation to density. Uniaxial tensile tests were conducted on the porcine thoracic aorta in four test regions (anterior, posterior, distal, and proximal), two loading directions (circumferential and longitudinal), and density increase rates (0%-12%). As a result, the PPC (Posterior/Proximal/Circumferential) group experienced a higher ultimate stress than the PDC (Posterior/Distal/Circumferential) group. However, this relationship reversed when the specimen density exceeded 3%. In addition, the ultimate stress of the ADC (Anterior/Distal/Circumferential) and PPC group was greater than that of the APC (Anterior/Proximal/Circumferential) group, while these findings were reversed when the specimen density exceeded 6% and 9%, respectively. Finally, the high slope of the PDL (Posterior/Distal/Longitudinal) group was lower than that of the ADL (Anterior/Distal/Longitudinal) group, but the high slope of the PDL group appeared larger due to the stabilization treatment. This highlights the potential impact of density variations on the mechanical properties of specific specimen groups.
ABSTRACT
BACKGROUND: Studies on varicose veins have focused its effects on physical function; however, whether nonsurgical treatments alter muscle oxygenation or physical function remains unclear. Moreover, the differences in such functions between individuals with varicose veins and healthy individuals remain unclear. AIM: To investigate changes in physical function and the quality of life (QOL) following nonsurgical treatment of patients with varicose veins and determine the changes in their muscle oxygenation during activity. METHODS: We enrolled 37 participants (those with varicose veins, n = 17; healthy individuals, n = 20). We performed the following measurements pre- and post-nonsurgical treatment in the varicose vein patients and healthy individuals: Calf muscle oxygenation during the two-minute step test, open eyes one-leg stance, 30 s sit-to-stand test, visual analog scale (VAS) for pain, Pittsburgh sleep quality index, physical activity assessment, and QOL assessment. RESULTS: Varicose veins patients and healthy individuals differ in most variables (physical function, sleep quality, and QOL). Varicose veins patients showed significant differences between pre- and post-nonsurgical treatment- results in the 30 sit-to-stand test [14.41 (2.45) to 16.35 (4.11), P = 0.018), two-minute step test [162.29 (25.98) to 170.65 (23.80), P = 0.037], VAS for pain [5.35 (1.90) to 3.88 (1.73), P = 0.004], and QOL [39.34 (19.98) to 26.69 (17.02), P = 0.005]; however, no significant difference was observed for muscle oxygenation. CONCLUSION: Nonsurgical treatment improved lower extremity function and QOL in varicose veins patients, bringing their condition close to that of healthy individuals. Future studies should include patients with severe varicose veins requiring surgery to confirm our findings.
ABSTRACT
BACKGROUND: Venous adventitial cystic disease (VACD) is a rare disease characterized by cysts, filled with a gelatinous mucous substance similar to joint fluid, in the adventitia of blood vessels adjacent to the joints. It is often misdiagnosed as deep vein thrombosis (DVT), femoral varices, venous tumors, or lymphadenopathy. CASE SUMMARY: A 69-year-old woman visited our hospital with a complaint of swelling in the right lower extremity. The patient was diagnosed with DVT and prescribed apixaban at an outpatient clinic. After 3 wk, the patient was hospitalized again because of sudden swelling in the right lower extremity. We diagnosed VACD and performed surgery for cyst removal as well as patch angioplasty and thrombectomy of the right common femoral vein. The patient received anticoagulants for 6 mo and has been doing well without recurrence for 1 year postoperatively. CONCLUSION: Recurrent VACD requires complete removal of the connections to the joint cavity to prevent recurrence.
ABSTRACT
T. gondii is a highly prevalent parasite worldwide, with cats serving as its final host. However, few studies have investigated the impact of T. gondii infection on cat gut microbiota. Therefore, this study examined the influence of T. gondii infection on the gut microbiota of stray cats and identified potential pathogens in their feces. This study examined T. gondii infection through blood of stray cats and the influence of microbiota in their feces using 16S rRNA gene amplicon sequencing. The results revealed significant differences in gut microbiota composition and diversity between the T. gondii seropositive and seronegative groups. Seropositive samples displayed a lower number of operational taxonomic units and reduced Shannon index than the seronegative samples. The seropositive and seronegative groups exhibited enrichment of taxa, including Escherichia and Enterobacteriaceae and Collinsella, Bifidobacterium, and Roseburia, respectively. Furthermore, potential pathogen species, including Campylobacter, Escherichia, and Streptococcus, were identified in the fecal samples. These findings suggest that T. gondii infection significantly impacts gut microbiota composition and diversity in stray cats. Additionally, an increased potential pathogen load, represented by Escherichia spp., was observed. These results underscore the importance of monitoring the prevalence of zoonotic pathogens in stray cats, as they can serve as reservoirs for zoonotic diseases.

Prone position is useful in reducing respiratory motion artifacts in lung nodules on 2-Deoxy-2-[18F] fluoro-D-glucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT). However, whether prone position PET/CT is useful in evaluating hepatic lesions is unknown. Thirty-five hepatic lesions from 20 consecutive patients were evaluated. The maximum standardized uptake value (SUVmax) and metabolic tumor volume (MTV) of both standard supine position PET/CT and additional prone position PET/CT were evaluated. No significant difference in SUVmax (4.41 ± 2.0 vs. 4.23 ± 1.83; p = 0.240) and MTV (5.83 ± 6.69 vs. 5.95 ± 6.24; p = 0.672) was observed between supine position PET/CT and prone position PET/CT. However, SUVmax changes in prone position PET/CT varied compared with those in supine position PET/CT (median, -4%; range: -30-71%). Prone position PET/CT was helpful when [18F]FDG uptake of the hepatic lesions was located outside the liver on supine position PET/CT (n = 4, SUVmax change: median 15%; range: 7-71%) and there was more severe blurring on supine position PET/CT (n = 6, SUVmax change: median 11%; range: -3-32%). Unlike in lung nodules, prone position PET/CT is not always useful in evaluating hepatic lesions, but it may be helpful in individual cases such as hepatic dome lesions.
ABSTRACT
Background: The optimal management strategy for aortoiliac occlusive disease (AIOD) remains debatable. This study compared early and late outcomes between direct surgical bypass and kissing stents for AIOD treatment. Methods: We retrospectively reviewed data, including age, sex, risk factors, comorbidities, symptoms, TransAtlantic Inter-Society Consensus (TASC) II classification, operation time, perioperative complications, in-hospital mortality, and length of hospital stay, from a cohort of 46 patients treated for AIOD (24 with kissing stents and 22 with direct surgical bypass) at Pusan National University Hostpital from January 2007 to December 2016. The primary, assisted primary, and secondary patency rates in both groups were compared. Results: The hospital stay (direct surgical bypass vs. kissing stents: 16.36±5.19 days vs. 9.08±10.88 days, p=0.007) and operation time (direct surgical bypass vs. kissing stents: 316.09±141.78 minutes vs. 99.54±37.95 minutes, p<0.001) were significantly shorter for kissing stents. Kaplan-Meier analysis revealed that the primary, assisted primary, and secondary patency rates in the direct surgical bypass group were 95.5%, 95.5%, and 95.5%, respectively, at 1 year; 86.4%, 86.4%, and 95.5% at 3 years; and 77.3%, 77.3%, and 95.5% at 5 years. The primary, assisted primary, and secondary patency rates in the kissing stent group were 100.0%, 100.0%, and 100.0%, respectively, at 1 year; 95.8%, 95.8%, and 100.0% at 3 years; and 95.8%, 95.8%, and 100.0% at 5 years. Conclusion: Except for special cases wherein endovascular revascularization is difficult, kissing stents are more advantageous for TASC II C and D lesions.
ABSTRACT
An arteriovenous fistula was required for permanent vascular access in a patient undergoing hemodialysis due to progressive chronic kidney disease associated with short bowel syndrome. In the present report, we discuss the case of a patient who underwent arteriovenous grafting because there was no proper native vein as a route, following which a seroma developed near the arterial anastomosis. Despite several surgical treatments, seroma not only recurred but also affected dialysis by compressing the graft. A stent was inserted into the graft to withstand the pressure from the seroma, and because one stent could not withstand the pressure, the stent overlapped where it received the most compression. Since then, the patency of graft has been well maintained for more than 2 years. Increasing the radial force of overlapping stents would be an alternative plan to help solve the problematic repeated compressible seroma despite multiple surgical treatments.

BACKGROUND: We report two cases of acute femoral artery occlusion following the use of ProGlide in minimally invasive cardiac surgery and insertion of large-bore catheters through the common femoral artery. This will add to the existing body of literature by highlighting the possible complications associated with the use of ProGlide and reiterate that the use of the sono-guided ProGlide skill will reduce the incidence of these complications. CASE SUMMARY: A 78-year-old man underwent minimally invasive cardiac surgery for severe aortic valve stenosis. After the operation, the puncture site of the common femoral artery was closed using ProGlide. The next morning, after regaining consciousness, he complained of pain, motor weakness (grade 2), and coldness in the right lower extremity. A 65-year-old man underwent minimally invasive cardiac surgery for a large secundum atrial septal defect (5 cm × 5 cm). After the operation, the puncture site of the common femoral artery was closed using ProGlide. After extubation, the patient complained of paresthesia of the right thigh. Both the patients underwent emergency surgery for acute occlusion of the common femoral artery. CONCLUSION: If the sono-guided ProGlide skill is used, complications can be prevented, and ProGlide can be safely used.
ABSTRACT
BACKGROUND: Extracranial cerebrovascular diseases represent approximately 20% of ischemic stroke cases. Carotid endarterectomy (CEA) was the gold standard procedure for carotid artery stenosis treatment until the introduction of carotid artery stenting (CAS) in the 1980s. While there have been several multicenter randomized trials comparing CEA and CAS, a more efficacious procedure has not been conclusively distinguished. This study reports the results of CAS versus CEA in patients with symptomatic or asymptomatic carotid stenosis and compares them with those from other studies. METHODS: This study is a single-center retrospective study and included patients who underwent CAS and CEA as elective surgery between January 2012 and December 2020. The final analysis included patient baseline characteristics, postoperative complications, and patient outcomes. RESULTS: The 235 patients included were assigned to the CAS (n=128) and CEA (n=107) groups. Within 30 days postoperatively, no significant differences were noted in myocardial infarction [n=1, 0.8% (CAS); n=1, 0.9% (CEA); P=0.899], cerebral infarction [n=4, 3.1% (CAS); n=1, 0.9% (CEA); P=0.247], and patient mortality [n=1, 0.8% (CAS); n=0, 0% (CEA); P=0.247]. CONCLUSIONS: In elective surgery, CAS and CEA had the same effect of preventing cerebral infarction with no difference in postoperative complications.

OBJECTIVE: Open or endovascular repair of abdominal aortic aneurysms (AAAs) can involve sacrifice of the internal iliac artery (IIA). In the present study, we investigated the effect of IIA exclusion on ischemic complications and overall mortality. METHODS: The data from 326 patients who had undergone elective open surgical or endovascular treatment of a nonruptured AAA from January 2010 to December 2019 in a tertiary hospital were retrospectively reviewed. Ischemic complications included buttock claudication, spinal ischemia (including paraparesis), ischemic colitis, lower limb paresthesia, and skin necrosis. Their duration and mortality during the study period were investigated. RESULTS: Nearly 50% of patients (148; 45.4%) had undergone endovascular aortic aneurysm repair and 178 (54.6%) had undergone open surgery. The median patient age was 78 years (range, 31-94 years). The median follow-up period was 1140 days (range, 0-4757 days). Of the 326 patients, 50 (15.3%) had died during follow-up. The bilateral IIAs were preserved in 187 patients (57.4%), a single IIA in 86 patients (26.4%), and no IIA in 53 patients (16.3%). Ischemic complications occurred in 57 patients (17.5%). Multivariable analysis revealed failure to preserve the bilateral IIAs (hazard ratio [HR], 8.65; 95% confidence interval [CI], 4.31-17.36; P < .01), management of the IIA (HR, 3.05, 95% CI, 2.17-4.28; P < .01), and hyperlipidemia (HR, 2.09; 95% CI, 1.04-4.17; P = .04) affected the occurrence of ischemic complications. Furthermore, univariable analysis revealed that patients had experienced more ischemic complications when a single IIA (HR, 6.97; 95% CI, 3.74-13.02; P < .01) or none of the IIAs had been preserved (HR, 8.88; 95% CI, 4.12-19.16; P < .01) than when both IIAs were preserved. Moreover, multivariable analysis revealed that stage 5 chronic kidney disease (HR, 2.7; 95% CI, 1.09-6.14; P = .03), age >75 years (HR, 2.48; 95% CI, 1.12-5.49; P = .03), cerebrovascular accident (HR, 1.95; 95% CI, 1.00-3.78; P = .05), and failure to preserve the bilateral IIAs (HR, 1.91; 95% CI, 1.02-3.46; P = .04) were associated with higher mortality after AAA repair. CONCLUSIONS: IIA exclusion is a risk factor for ischemic complications and overall mortality. Thus, preservation of the IIA as much as possible during AAA repair is recommended.
