Role of the medial agranular cortex in unilateral spatial neglect.

Unilateral spatial neglect (USN) results from impaired attentional networks and can affect various sensory modalities, such as visual and somatosensory. The rodent medial agranular cortex (AGm), located in the medial part of the forebrain from rostral to caudal direction, is considered a region associated with spatial attention. The AGm selectively receives multisensory input with the rostral AGm receiving somatosensory input and caudal part receiving visual input. Our previous study showed slower recovery from neglect with anterior AGm lesion using the somatosensory neglect assessment. Conversely, the functional differences in spatial attention across the entire AGm locations (anterior, intermediate, and posterior parts) are unknown. Here, we investigated the relationship between the severity of neglect and various locations across the entire AGm in a mouse stroke model using a newly developed program-based analysis method that does not require human intervention. Among various positions of the lesions, the recovery from USN during recovery periods (postoperative day; POD 10-18) tended to be slower in cases with more rostral lesions in the AGm (r = - 0.302; p = 0.028). Moreover, the total number of arm entries and maximum moving speed did not significantly differ between before and after AGm infarction. According to these results, the anterior lesions may slowly recover from USN-like behavior, and there may be a weak association between the AGm infarct site and recovery rate. In addition, all unilateral focal infarctions in the AGm induced USN-like behavior without motor deficits.

Pirogoff amputation is a viable option to maintain ambulation in chronic limb-threatening ischemia with extensive midfoot tissue loss: a report of two cases.

Eliminating necrotic and infected tissues is crucial for limb salvage in patients with chronic limb-threatening ischemia (CLTI). However, extensive lesions that involve the midfoot frequently result in transtibial amputation, restricting ambulation and independent life. The Modified Pirogoff amputation, which includes a 90° rotation of the calcaneus and fixation with the tibia, has good functional outcomes in trauma cases. Here, we report two patients with CLTI successfully managed by a combination of revascularization and modified Pirogoff amputation, resulting in preserved ambulation without a prosthesis. Modified Pirogoff amputation may be a good alternative in revascularized CLTI with extensive tissue loss of the midfoot.

Three-dimensional imaging evaluation of facial swelling after orthognathic surgery with compression and Kinesio taping therapy: a randomized clinical trial.

Background: Postoperative swelling is a common complication of orthognathic surgery. The authors used three-dimensional (3D) image analysis and body surface temperature to determine the effects of compression taping (CT) and Kinesio taping (KT) by the epidermis, dermis, and fascia method (EDF-KT) on postoperative swelling. Materials and methods: The authors conducted a prospective, parallel-group, randomized controlled trial. Among the 162 patients diagnosed with jaw deformity and who underwent orthognathic surgery from August 2020 to October 2022, 105 patients (men: 36, women: 69, mean age: 28.27±8.92) underwent Le Fort type I + sagittal split ramus osteotomy (SSRO) or SSRO and were included in this study. Patients were randomly divided into three groups: EDF-KT group (n=31), CT group (n=41), and no tape group (control group, n=30). All taping was performed immediately postoperatively and removed on postoperative day (POD) 5. Three-dimensional images of the participants' faces were obtained preoperatively and at PODs 3, 7, 30, and 90 using a hand-held 3D imaging system and infrared thermography. Results: No significant difference was observed in postoperative swelling and postoperative body surface temperature between the groups at each time point. The CT group showed a trend towards reduced swelling on PODs 3 and 7 and a trend toward residual swelling on POD 90. The EDF-KT group showed a trend towards an increase in postoperative body surface temperature. Conclusion: CT taping may not be appropriate for postoperative swelling control, suggesting that EDF-KT may affect body surface temperature. Further validation of the efficacy of KT for jaw deformities is needed.

A Predictive Strategy for Nonsurgical Management of Pancreatic Stones.

OBJECTIVES: We set out to predict whether nonsurgical treatment is likely to succeed in removing pancreatic stones in a given patient and also to determine an optimal maximal number of extracorporeal shock wave lithotripsy (ESWL) sessions for treatment of pancreatolithiasis in that patient. MATERIALS AND METHODS: We ascertained the number of ESWL sessions for each of 164 patients undergoing that treatment for pancreatolithiasis between 1992 and 2020. Median follow-up duration was 31 months (range, 0-239), median age was 58 years (22-83), and the male to female ratio was 5.1:1.0. Patients were divided into 2 groups based upon an optimal maximal number of ESWL sessions determined by receiver operating characteristic analysis. RESULTS: Total stone clearance was achieved in 130 of 164 patients (79%). The median number of ESWL sessions was 3 (1-61). Receiver operating characteristic analysis determined 7 to be the optimal maximal number of sessions. Complete clearance was more frequent (87%) among the 131 patients requiring 7 or fewer ESWL sessions than among the 33 undergoing more (48%, P < 0.001). Seventeen patients (52%) undergoing 8 or more sessions still had residual stones. CONCLUSIONS: If any pancreatic stones persist after 7 ESWL sessions, we recommend transition to medical or surgical treatments.

Analysis of histone H3K4me3 modifications in bovine placenta derived from different calf-production methods.

In ruminants, the overgrowth of offspring produced by in vitro fertilization (IVF) is a common problem. Abnormal epigenetic modifications caused by environmental factors during the early embryonic period are suspected as an aetiology of overgrowth. In this study, we investigated the genome-wide histone H3K4me3 profiles of bovine placentae that play a pivotal role in foetal development and compared their characteristics between artificial insemination (AI)- and IVF-derived samples. Cotyledons were harvested from the placentae obtained at parturition of 5 AI- and 13 IVF-derived calves, and chromatin immunoprecipitation sequencing was performed for H3K4me3. We confirmed no significant maternal tissue contamination in the samples we used. The revealed H3K4me3 profiles reflected the general characteristics of the H3K4me3 modification, which is abundantly distributed in the promoter region of active genes. By extracting common modifications from multiple samples, the genes involved in placenta-specific biological processes could be enriched. Comparison with the H3K4me3 modifications of blastocyst samples was also effective for enriching the placenta-specific features. Principal component analysis suggested the presence of differential H3K4me3 modifications in AI- and IVF-derived samples. The genes contributing to the difference were related to the developmental biological processes. Imprinted genes such as BEGAIN, ZNF215 and DLX5 were among the extracted genes. Principal component and discriminant analyses using only male samples categorized the samples into three groups based on foetal weight and calf-production methods. To our knowledge, this is the first study to profile the genome-wide histone modifications of bovine foetal placentae and reveal their differential characteristics between different calf-production methods.

Effect of in-patient cardiac rehabilitation at rehabilitation hospital for cardiology patients: two-center trial.

The effectiveness of cardiac rehabilitation (CR) in patients with cardiovascular disease requiring continuous CR from an acute care hospital to a convalescent rehabilitation hospital is unknown. Therefore, we compared the effect of CR in a rehabilitation hospital for patients with cardiovascular disease with that of those who underwent cardiovascular surgery. Sixty-nine consecutive patients were admitted to two rehabilitation hospitals for CR. Patients were classified by primary disease into two groups: patients with cardiovascular disease (cardiology group, 26 patients) and patients who underwent cardiovascular surgery (surgery group, 43 patients). Clinical information, physical function, cognitive function, activities of daily living (ADL), quality of life (QOL), amount of CR, and length of hospital stay were compared between the two groups. Compared with clinical features, age was significantly higher in the cardiology group (P < 0.001), and the preadmission Barthel index was significantly lower in the cardiology group (P = 0.025). Physical function at the time of transfer was significantly lower in the cardiology group than in the surgery group for the short physical performance battery (P < 0.001), gait speed (P = 0.005), and 6-min walking distance (P = 0.042). No significant difference was found in the amount of CR performed or the length of hospital stay, and no interaction effects were observed in improvements in physical function, exercise tolerance, or QOL. In conclusion, in rehabilitation hospitals, patients with cardiovascular disease were older, had lower preadmission ADL, and had lower a physical function at transfer than those who underwent cardiovascular surgery, but CR improved physical function and QOL to the same extent. The results suggest that the recovery of patients with cardiovascular disease may be similar to those who undergo cardiovascular surgery.

Prolonged shedding of viable SARS-CoV-2 in immunocompromised patients with haematological malignancies: A prospective study.

Prolonged SARS-CoV-2 infection in immunocompromised individuals has been scattered, but the details remain unclear. We conducted a prospective study with 26 COVID-19 patients with haematological malignancies to determine viral shedding kinetics and characteristics. We obtained nasopharyngeal swabs from the patients 21-28 days post-onset for a PCR test and performed virus isolation from the PCR-positive samples. A viable virus was detected in five patients (19.2%), all of whom had malignant lymphoma. Those patients had significantly lower CD4+ T-cell counts than the PCR-negative patients. A comparison of previous chemotherapy showed that anti-CD20 antibodies and bendamustine may be risk factors for prolonged viral shedding.

Delayed Extubation of a Patient With Multiple Sclerosis.

The potential complications associated with gastroparesis in the perioperative setting for patients with multiple sclerosis (MS) are inadequately recognized. While gastroparesis is commonly associated with diabetes mellitus-induced neuropathy and postsurgical complications, its prevalence and impact on patients with MS are less understood. This is particularly crucial as the systemic autoimmune nature of MS may extend its neurological effects to the gastrointestinal (GI) tract. In this context, we present a case wherein undiagnosed gastroparesis significantly contributed to postoperative challenges, leading to delayed extubation in a patient with MS. This underscores the importance of considering gastroparesis as a potential differential diagnosis and developing a comprehensive approach to evaluating and managing MS patients, which may help mitigate perioperative complications and inform tailored anesthetic management strategies.

The role of contrast-enhanced endoscopic ultrasound for biliary diseases.

Contrast-enhanced endoscopic ultrasound (CE-EUS) has emerged as a promising diagnostic modality for assessing biliary diseases. CE-EUS is a noninvasive imaging technique that utilizes contrast agents to enhance the visualization of blood vessels and perfusion within target tissues. In the context of biliary diseases, CE-EUS allows for improved characterization of biliary lesions, aiding in differential diagnosis and treatment planning. This review highlights several key findings regarding the usefulness of CE-EUS in biliary disease assessment and therapeutic procedures.

Safety and clinical efficacy of an anti-PD-L1 antibody (c4G12) in dogs with advanced malignant tumours.

Immune checkpoint inhibitors (ICIs) have been developed for canine tumour treatment, and pilot clinical studies have demonstrated their antitumour efficacy in dogs with oral malignant melanoma (OMM). Although ICIs have been approved for various human malignancies, their clinical benefits in other tumour types remain to be elucidated in dogs. Here, we conducted a clinical study of c4G12, a canine chimeric anti-PD-L1 antibody, to assess its safety and efficacy in dogs with various advanced malignant tumours (n = 12) at the Veterinary Teaching Hospital of Hokkaido University from 2018 to 2023. Dogs with digit or foot pad malignant melanoma (n = 4), osteosarcoma (n = 2), hemangiosarcoma (n = 1), transitional cell carcinoma (n = 1), nasal adenocarcinoma (n = 1), B-cell lymphoma (n = 1), or undifferentiated sarcoma (n = 2) were treated with 2 or 5 mg/kg c4G12 every 2 weeks. Treatment-related adverse events of any grade were observed in eight dogs (66.7%), including elevated aspartate aminotransferase (grade 3) in one dog (8.3%) and thrombocytopenia (grade 4) in another dog (8.3%). Among dogs with target disease at baseline (n = 8), as defined by the response evaluation criteria for solid tumours in dogs (cRECIST), one dog with nasal adenocarcinoma and another with osteosarcoma experienced a partial response (PR), with an objective response rate of 25.0% (2 PR out of 8 dogs; 95% confidence interval: 3.2-65.1%). These results suggest that c4G12 is safe and tolerable and shows antitumor effects in dogs with malignant tumours other than OMM. Further clinical studies are warranted to identify the tumour types that are most likely to benefit from c4G12 treatment.

Electrochemical Li+ Insertion/Extraction Reactions at LiPON/Epitaxial Graphene Interfaces.

Redox reactions of the Li+ insertion/extraction from one to two interlayers of graphene (Gr) on area-defined single-crystalline SiC substrates are investigated using lithium phosphorus oxynitride glass (LiPON) as the solid-state electrolyte. Unlike an organic liquid electrolyte, this glassy electrolyte does not induce a reduction current and excludes the desolvation reaction of Li+. Gr electrodes with less than two Gr layers show a single reduction peak and one or two oxidation peaks below +0.21 V (vs Li+/Li), differing distinctly from those of graphite and multilayer Gr, which display multiple peaks (multiple stage transitions). However, this finding aligns with the conventional understanding that graphite stage structure transitions proceed with stepwise increases or decreases in the number of Gr layers between adjacent Li-inserted interlayers. Cyclic voltammetry measurements indicate the presence of surface capacity due to Li+ adsorption/desorption at the LiPON/Gr interface. Moreover, Li+ insertion and extraction induce different charge transfer resistances at the level of a single interlayer. These sensitive measurements are achieved using high-quality epitaxial Gr and LiPON electrolyte, which prevent the formation of a solid electrolyte interphase and the desolvation reaction of Li+. Similar measurements using bilayer Gr produced by chemical vapor deposition coupled with a Gr transfer method and an ethylene carbonate/dimethyl carbonate liquid electrolyte are not reliable. Thus, the proposed method is effective for electrochemical measurement of Gr electrodes with a controlled number of layers.

Dominant-negative type of IKZF1 deletion showed a favorable prognosis in adult B-cell acute lymphoblastic leukemia.

IKZF1 deletion is a recurrent genomic alteration in B-cell acute lymphoblastic leukemia (B-ALL) and is divided into dominant-negative (DN) and loss of function (LOF) deletions. The prognostic impact of each deletion has not been fully elucidated. We retrospectively analyzed 117 patients with adult B-ALL including 60 patients with BCR::ABL1-positive B-ALL and 57 patients with BCR::ABL1-negative B-ALL by the fluorescence in situ hybridization (FISH) method for IKZF1 deletion and multiplex PCR for the 4 most common IKZF1 deletions (∆4-7, ∆2-7, ∆2-8, and ∆4-8). Samples, in which IKZF1 deletion was detected by FISH but a specific type of deletion was not identified by the PCR, were categorized as "other." Patients were classified into a DN group that had at least 1 allele of ∆4-7 (n = 23), LOF and other group (n = 40), and wildtype group (n = 54). DN type IKZF1 deletions were found in 33.3% of BCR::ABL1-positive cases and 5.2% of BCR::ABL1-negative cases. LOF and other type IKZF1 deletions were found in 43.4% of BCR::ABL1-positive cases and 24.6% of BCR::ABL1-negative cases. Patients with the DN group showed significantly higher overall survival (OS) than that of the LOF and other and WT groups (P = 0.011). Multivariate analysis including age, WBC counts, complex karyotype, and DN type IKZF1 deletion showed that the DN type of IKZF1 deletion (HR = 0.22, P = 0.013) had a positive impact and age ≥ 65 (HR = 1.92, P = 0.029) had a negative impact on OS. The prognostic impact of IKZF1 deletion depends on the type of deletion and DN type of IKZF1 deletion showed better prognosis in adult B-ALL patients.Clinical trial registration This study was part of a prospective observational study (Hokkaido Leukemia Net, UMIN000048611). It was conducted in compliance with ethical principles based on the Helsinki Declaration and was approved by the institutional review board of Hokkaido University Hospital (#015-0344).

Primary sclerosing cholangitis with partial steroid responsiveness: a case report.

A 69-year-old woman suspected to have IgG4-related sclerosing cholangitis causing bile duct stenosis was transferred from another hospital after diarrhea, eosinophilia, and eosinophilic infiltration were detected and prednisolone was prescribed. Additional biliary imaging suggested primary sclerosing cholangitis, but the IgG4 level and inferior bile duct stenosis were alleviated by steroid therapy, suggesting IgG4-related sclerosing cholangitis. Therefore, prednisolone was continued. Bile duct biopsy findings suggesting adenocarcinoma led to a diagnosis of pancreatoduodenectomy. The latter specimen only displayed evidence of primary sclerosing cholangitis, and prednisolone was discontinued. Intractable cholangitis necessitated left hepatectomy, after which serum alkaline phosphatase levels increased and eosinophilic colitis recurred. The reintroduction of prednisolone effectively managed the diarrhea but only temporarily reversed the alkaline phosphatase elevation. When histologic sections from resection specimens were compared, the hepatectomy specimen exhibited greater eosinophil infiltration than the earlier pancreatoduodenectomy specimen, suggesting eosinophilic cholangiopathy superimposed on primary sclerosing cholangitis.

Large or multiple pseudocysts can impede or complicate the nonsurgical treatment of pancreatolithiasis.

Objectives: We aimed to determine when a coexisting pseudocyst was likely to complicate the nonsurgical treatment of pancreatolithiasis. Methods: We treated 165 patients with pancreatolithiasis nonsurgically between 1992 and 2020, including 21 with pseudocysts. Twelve patients had a single pseudocyst less than 60 mm in diameter. Pseudocysts in the other nine patients had diameters of at least 60 mm or were multiple. The locations of pseudocysts along the length of the pancreas varied from the area with stone involvement to the pancreatic tail. We compared the outcomes in these groups. Results: We found no significant differences in pain relief, stone clearance, stone recurrence, or the likelihood of adverse events between pseudocyst groups or between patients with vs without pseudocysts. However, 4 of 9 patients with large or multiple pseudocysts required transition to surgical treatment (44%) compared with 13 of 144 patients with pancreatolithiasis and no pseudocyst (9.0%) (P=0.006). Conclusions: Patients with smaller pseudocysts typically underwent nonsurgical stone clearance successfully with few adverse events, similar to findings in patients with pancreatolithiasis and no pseudocysts. Pancreatolithiasis complicated by large or multiple pseudocysts did not cause more adverse events but was more likely to require transition to surgery compared with pancreatolithiasis without pseudocysts. In patients with large or multiple pseudocysts, early transition to surgery should be considered when nonsurgical treatment is ineffective.

Use of Robot-Assisted Ankle Training in a Patient with an Incomplete Spinal Cord Injury: A Case Report.

Rehabilitation interventions are crucial in promoting neuroplasticity after spinal cord injury (SCI). We provided rehabilitation with a single-joint hybrid assistive limb (HAL-SJ) ankle joint unit (HAL-T) in a patient with incomplete SCI. The patient had incomplete paraplegia and SCI (neurological injury height: L1, ASIA Impairment Scale: C, ASIA motor score (R/L) L4:0/0, S1:1/0) following a rupture fracture of the first lumbar vertebra. The HAL-T consisted of a combination of ankle plantar dorsiflexion exercises in the sitting position, knee flexion, and extension exercises in the standing position, and stepping exercises in the standing position with HAL assistance. The plantar dorsiflexion angles of the left and right ankle joints and electromyograms of the tibialis anterior and gastrocnemius muscles were measured and compared using a three-dimensional motion analyzer and surface electromyography before and after HAL-T intervention. Phasic electromyographic activity was developed in the left tibialis anterior muscle during plantar dorsiflexion of the ankle joint after the intervention. No changes were observed in the left and right ankle joint angles. We experienced a case in which intervention using HAL-SJ induced muscle potentials in a patient with a spinal cord injury who was unable to perform voluntary ankle movements due to severe motor-sensory dysfunction.

Intraoperative Spinal Cord Stimulation Mitigates Central Sensitization After Spine Surgery in Mice.

STUDY DESIGN: Double-blinded, prospective laboratory animal study. OBJECTIVE: To examine whether intraoperative spinal cord stimulation (SCS) inhibits the development of spine surgery-induced hypersensitivity. SUMMARY OF BACKGROUND DATA: Managing postoperative pain after spine surgery is challenging, and as many as 40% of patients may develop failed back surgery syndrome. Although SCS has been shown to effectively reduce chronic pain symptoms, it is unknown whether intraoperative SCS can mitigate the development of central sensitization that causes postoperative pain hypersensitivity and potentially leads to failed back surgery syndrome after spine surgery. MATERIALS AND METHODS: Mice were randomly stratified into three experimental groups: (1) sham surgery, (2) laminectomy alone, and (3) laminectomy plus SCS. Secondary mechanical hypersensitivity was measured in hind paws using von Frey assay one day before and at predetermined times after surgery. In addition, we also performed a conflict avoidance test to capture the affective-motivational domain of pain at selected time points postlaminectomy. RESULTS: Mice that underwent unilateral T13 laminectomy developed mechanical hypersensitivity in both hind paws. Intraoperative SCS applied to the exposed side of the dorsal spinal cord significantly inhibited the development of hind paw mechanical hypersensitivity on the SCS-applied side. Sham surgery did not produce any obvious secondary mechanical hypersensitivity in the hind paws. CONCLUSIONS: These results demonstrate that spine surgery for unilateral laminectomy induces central sensitization that results in postoperative pain hypersensitivity. Intraoperative SCS after laminectomy may be able to mitigate the development of this hypersensitivity in appropriately selected cases.

Prognostic impact of FLT3-ITD, NPM1 mutation and CEBPA bZIP domain mutation in cytogenetically normal acute myeloid leukemia: a Hokkaido Leukemia Net study.

Mutation status of FLT3, NPM1, and CEBPA is used to classify the prognosis of acute myeloid leukemia, but its significance in patients with cytogenetically normal (CN) AML is unclear. We prospectively analyzed these genes in 295 patients with CN-AML and identified 76 (25.8%) FLT3-ITD, 113 (38.3%) NPM1 mutations, and 30 (10.2%) CEBPA biallelic mutations. We found that patients with FLT3-ITD had a poor prognosis at any age, while patients with CEBPA biallelic mutation were younger and had a better prognosis. FLT3-ITD and NPM1 mutations were correlated, and the favorable prognostic impact of being FLT3-ITD negative and NPM1 mutation positive was evident only in patients aged 65 years or more. For CEBPA, 86.7% of the patients with biallelic mutation and 9.1% of patients with the single allele mutation had in-frame mutations in the bZIP domain, which were strongly associated with a favorable prognosis. Multivariate analysis showed that age < 65 years, FLT3-ITD and CEBPA bZIP in-frame mutation were independent prognostic factors. The results suggest that analyzing these gene mutations at diagnosis can inform selection of the optimal intensity of therapy for patients with CN-AML.

Epidemiology of Subarachnoid Hemorrhage in Isolated Islands in Japan: A Population-based Study in the Miyako Islands.

The Miyako Islands (with a population of approximately 50,000) are located in southwestern Japan, with a subtropical oceanic climate. This isolated location permitted a retrospective population-based epidemiological study of subarachnoid hemorrhage. We retrospectively enrolled 110 consecutive patients from 2010 to 2019 using the subarachnoid hemorrhage database at Okinawa Miyako Hospital, which is the only local facility with neurosurgeons. We calculated the incidence of subarachnoid hemorrhage standardized to the entire Japanese population. The seasonal distribution of subarachnoid hemorrhage onset and patients' epidemiological characteristics were also investigated. The standardized annual incidence of subarachnoid hemorrhage was 21.4 per 100,000 population, as reported previously in Japan. The patients' mean age was 62.1 ± 15.4 years, and women constituted 60.9%. Anterior communicating artery aneurysms were most common. The endovascular treatment for ruptured aneurysms was increasing as standard levels in Japan. The rates of symptomatic vasospasm and secondary hydrocephalus requiring additional neurosurgical treatment were 2.7% and 19.1%, respectively. The mortality rate was 23.6%. The percentage of patients with a modified Rankin scale score of 0-2 at discharge was 55.5%. There were no differences in the frequency of subarachnoid hemorrhage associated with seasonal distribution or climatic factors. The incidence, baseline characteristics, and clinical outcomes of subarachnoid hemorrhage in the Miyako Islands were similar to those in other regions of Japan. There are preferable epidemiological backgrounds for further practical clinical research.

Long-Term Outcomes following Common Femoral Endarterectomy.

Thromboendarterectomy of the common femoral artery (CFA) for occlusive disease is a crucial procedure in vascular surgery. As an outcome reference for emerging endovascular procedures and new devices, we need more robust evidence of the outcome of this gold standard technique. The purpose of this study was to report 10-year results after femoral endarterectomy (FEA). A retrospective review of medical records at our institution identified eighty consecutive patients (91 limbs) who underwent FEA for CFA lesions. Indications for FEA included 50 limbs (55%) for intermittent claudication (IC) and 39 limbs (43%) with chronic limb-threatening ischemia (CLTI). Two limbs (2%) underwent FEA to prevent hemodynamic steal during extra-anatomical bypass. Adjunctive procedures included endovascular therapy in 32%. CFAs were closed with patch angioplasty in 44%. With a mean follow-up period of 39 months, the survival rates at 3 and 8 years were 85% and 77%, respectively. Limb salvage rates were 92% and 87%. Primary patencies were 98% and 84%. Freedom from target lesion revascularization was 95% at 3 years and 91% at 8 years. Our findings support the durability of FEA, with comparable long-term procedural results in CLTI patients as well as IC patients. Since the FEA is a gate maneuver for hybrid revascularization in CLTI patients, our findings support a strategy combining open and endovascular approaches. Femoral endarterectomy remains a durable solution for common femoral occlusive disease in IC and CLTI in the era of endovascular therapy.
