Percutaneous injection of minocycline in postoperative sialocele following condylar fracture.

Sialocele is a common complication of parotid tumour surgery. Aspiration and pressure dressing are the most common conservative treatments for sialoceles. However, they occasionally exhibit a refractory nature. In this case report, a minocycline injection was administered for refractory sialocele following a condylar fracture treated using the retromandibular anterior transparotid approach. Aspiration of the sialocele and the same amount of minocycline injection using three-way stopcocks were performed four weeks after surgery. After the injection, the buccal swelling completely disappeared without complications, including facial palsy. Percutaneous injection of minocycline might be the first choice for postoperative refractory sialocele following condylar fracture.

Unilateral Surgical Treatment of Severe Deviated Condylar Base Fracture in Pediatric Bilateral Condylar Fracture: 12-Year Follow-Up.

Pediatric condylar fractures are commonly managed conservatively, as the condyle typically exhibits spontaneous remodeling. However, should conservative treatment be administered for severe deviated condylar processes? In a case involving a 7-year-5-month-old girl who fell from a height of 3 m, she sustained a mandibular parasymphysis fracture and bilateral condylar fractures, including a condylar base fracture with 60-degree medial deviation on the right side and a condylar head fracture, Neff type A, on the left side. To address the fractures, internal fixation was performed on the right condyle via a classical retromandibular approach, and a mini-plate was removed four months postsurgery. At a follow-up 12 years and 7 months later, the patient showed normal occlusion, TMJ function, and no visible scars. In addition, there was no facial deviation, although the surgical site condyle was larger than the nonsurgical site, suggesting that the surgical site facilitated normal growth while the nonsurgical site impeded it.

An exploratory study of the efficacy and safety of amenamevir for the treatment of herpes zoster in patients receiving immunosuppressive drugs.

Amenamevir is an oral once-daily antiherpesvirus drug that can be administered without dose adjustment in patients with impaired renal function. There are currently no clinical data on immunocompromised patients with herpes zoster treated with amenamevir. Therefore, an exploratory study of the efficacy and safety of amenamevir against herpes zoster in patients with immunosuppression was conducted. Inclusion criteria included patients with acute herpes zoster receiving immunosuppressive drugs or those with malignant tumors or autoimmune diseases. Twenty-four patients were included and received amenamevir (400 mg once daily after meals) for up to 14 days. The primary end point of overall improvement in skin symptoms 7 days after treatment initiation (day 7) was 58.3% for "markedly improved" and 20.8% for "improved." The combined improvement rate was 79.2% (95% confidence interval, 57.8-92.9), and 20.8% of patients experienced "worsened" symptoms. The secondary end points of overall improvement in skin symptoms on day 14 and day 28 were 95.7% and 100%, respectively. The skin symptoms progressed during treatment, peaking on day 7, and then began to heal. By Kaplan-Meier estimation, the median periods to complete crusting and healing were both day 14. There were five adverse events with a possible causal relationship to amenamevir (bacterial skin infection, anemia, hyponatremia, headache, and abnormal liver function) in one of the 24 patients. Although the bacterial skin infection was severe, all events in this patient were reported to be either recovered or recovering. These findings indicate that amenamevir can be effective and safe in immunocompromised patients with herpes zoster. However, as worsening can happen around day 7, it is necessary to carefully monitor such patients and switch to other therapies such as intravenous acyclovir if necessary.

Three-dimensional Hemifacial Microsomia Classification with New Subtypes Based on the Pruzansky and Kaban Classification.

Background: Various classifications of hemifacial microsomia (HFM) have been described previously. Although some of these classifications are used widely, others use external outlines of reference organs, even in three-dimensional (3D) images. The purpose of this study was to investigate the 3D characteristics of the mandibular condyle in HFM and to update the Pruzansky and Kaban classification as a 3D classification. Methods: Fifty-three patients with HFM were classified according to the Pruzansky and Kaban classification (type I, IIA, IIB, and III) using computed tomographic scan images. 3D images of the mandible were isolated, and the 3D characteristics were observed; furthermore, the angle of inclination of the mandibular condyle was measured in 3D. Results: Subtypes of retroflexed mandibular condyle in 3D were observed in the Pruzansky and Kaban classification type IIA and IIB, termed as type IIAß (33.3% in type IIA) and type IIBß (100% in type IIB). Although some differences were observed in the inclination of the mandibular condyle between the control and the affected sides in type I and IIAα, multiple differences were observed in type IIAß and IIBß. Conclusions: To the best of our knowledge, this is the first report that identified the retroflexed mandibular condyle as subtypes type IIAß and IIBß. Notably, this could not be identified in the two-dimensional images (lateral cephalogram) yet. We proposed to update the Pruzansky and Kaban classification as a 3D classification with a new 3D subtype. The angle of the retroflexed mandibular condyle may predict mandibular growth in HFM.

Varying Impact of Lenvatinib or Sorafenib Therapy on Skeletal Muscle Loss in Patients with Hepatocellular Carcinoma.

INTRODUCTION: Lenvatinib and sorafenib are key therapeutic agents for hepatocellular carcinoma (HCC). However, there are no useful biomarkers for selecting molecular-targeted agents (MTAs). Skeletal muscle volume is associated with the clinical outcomes in these patients. We investigated the effects of lenvatinib and sorafenib on the skeletal muscles of patients with HCC. METHODS: We evaluated the impact of skeletal muscle changes over a 3-month period for each MTA (n = 117; lenvatinib/sorafenib, 45/72). The skeletal muscle mass index (SMI) was measured at the third lumbar vertebra. Furthermore, we evaluated the direct effect of each MTA on primary human skeletal muscle cells by estimating muscle protein synthesis using western blot analysis. RESULTS: The median change in SMI was -0.7% (p = 0.959) and -5.9% (p < 0.001) for the lenvatinib and sorafenib groups, respectively. Sorafenib had a greater effect on skeletal muscle loss than lenvatinib (p < 0.001). Additionally, SMI significantly decreased in the sorafenib group regardless of initial skeletal muscle volume (p < 0.001), whereas no significant differences were observed in the lenvatinib group. Sorafenib therapy (odds ratio [OR], 2.98; p = 0.023) and non-muscle depletion (OR, 3.31; p = 0.009) were associated with a decreased SMI. In vitro analysis showed that sorafenib negatively affected muscle synthesis compared to lenvatinib. CONCLUSIONS: Sorafenib may have a more negative effect on skeletal muscle than lenvatinib.

Safety and Clinical Effects of a Muse Cell-Based Product in Patients With Amyotrophic Lateral Sclerosis: Results of a Phase 2 Clinical Trial.

Amyotrophic lateral sclerosis (ALS) is characterized by progressive loss of motor neurons. Multilineage-differentiating stress-enduring (Muse) cells are unique endogenous stem cells that show therapeutic effects on motor function in ALS mouse models. We conducted a single-center open phase II clinical trial to evaluate the safety and clinical effects of repeated intravenous injections of an allogenic Muse cell-based product, CL2020, in patients with ALS. Five patients with ALS received CL2020 intravenously once a month for a total of six doses. The primary endpoints were safety and tolerability, and the secondary endpoint was the rate of change in the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score. In addition, serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), sphingosine-1-phosphate (S1P), cerebrospinal fluid chitotriosidase-1 (CHIT-1), and neurofilament light chain (NfL) levels were evaluated. The CL2020 treatment was highly tolerated without serious side effects. The ALSFRS-R score change trended upward at 12 months post-CL2020 treatment compared with that at 3 months pre-administration, but the difference was not statistically significant. Among five patients diagnosed with ALS, three exhibited a decrease in the rate of ALSFRS-R score change, one demonstrated an increase, and another showed no change. In addition, the patients' serum IL-6 and TNF-α levels and cerebrospinal fluid CHIT-1 and NfL levels increased for up to 6 months post-treatment; however, their serum S1P levels continuously decreased over 12 months. These findings indicate a favorable safety profile of CL2020 therapy. In the near future, a double-blind study of a larger number of ALS patients should be conducted to confirm the efficacy of ALS treatment with CL2020.

Accessory fragment migration in a professional baseball player with bipartite patella: A case report.

INTRODUCTION: Bipartite patella (BP) is usually recognized as an incidental radiographic finding. Therefore, no reports have observed the process of accessory fragment migration. We present the case of a professional baseball pitcher with significant migration of the fragment during follow-up. PRESENTATION OF CASE: A 26-year-old man was diagnosed with symptomatic BP and underwent conservative therapy. Eleven months later, he was unable to play baseball because of gradually worsening knee pain without obvious trauma. On radiographs, the accessory fragment which had located at the superolateral pole 11 months earlier migrated posterolaterally. The diagnosis of Saupe's type III BP was established, and open excision of the accessory fragment was performed. Postoperatively, full-weight-bearing walking and range-of-motion exercises were started the day after surgery. Three months after surgery, he could pitch with all his power without pain. DISCUSSION: Since our patient was a professional baseball right-handed pitcher who needed to step strongly on his left knee during pitching, strong traction force from the vastus lateralis was likely to have been repeatedly applied to the accessory fragment. It might lead to migration of the accessory fragment. The open excision of the accessory fragment was performed because the accessory fragment had migrated away from the patella body. CONCLUSION: We report a case of professional baseball player with symptomatic BP, in which case the chronological migration of the accessory fragment was observed without obvious trauma. When the accessory fragment is identified without obvious trauma, one of the differential diseases could be a BP.

The use of tourniquet is useful in terms of blood loss and soft tissue damage in arthroscopic anterior cruciate ligament reconstruction: a retrospective study.

Whether a tourniquet should be used for anterior cruciate ligament reconstruction (ACLR) when the operative field is secured remains controversial. Little is known about the influence of not using a tourniquet on total perioperative blood loss and soft tissue damage. The aim of this study was to compare total perioperative blood loss and soft tissue damage with and without tourniquet use during ACLR. Seventy-seven consecutive ACLRs in 76 patients were performed without tourniquet use at our hospital and enrolled in this study (T- group) between November 2018 and September 2021. The control group (T + group) comprised 55 historical ACLRs in 55 patients performed with tourniquet use at our hospital between April 2017 and September 2018. Total perioperative blood loss, calculated from the change in hemoglobin between that preoperatively and on postoperative day (POD) 1, and indicators of soft tissue damage including serum white blood cell (WBC) counts, creatine phosphokinase (CPK), and C-reactive protein (CRP) values measured on POD 1 and POD 7 were compared between groups. Total blood loss was significantly higher in the T- group (339 ± 216 mL) than in the T + group (258 ± 199 mL; P = 0.030). On POD 1, WBC counts were significantly higher in the T- group (9.7 ± 2.4 × 103 cells/µL) than in the T + group (9.1 ± 2.5 × 103 cells/µL; P = 0.043), CPK levels were significantly higher in the T- group (294 ± 417 U/L) than in the T + group (255 ± 88 U/L; P = 0.046), and CRP levels were also significantly higher in the T- group (1.40 ± 1.12 mg/dL) than in the T + group (0.91 ± 0.76 mg/dL; P = 0.016). No significant differences in WBC counts or CPK or CRP levels were seen between groups on POD 7. Total blood loss and soft tissue damage were significantly increased without tourniquet use during ACLR. No advantage was found for not using a tourniquet in terms of blood loss or soft tissue damage.

Human Cord Blood-Endothelial Progenitor Cells Alleviate Intimal Hyperplasia of Arterial Damage in a Rat Stroke Model.

Human cord blood-endothelial progenitor cells (hCB-EPCs) isolated from the human umbilical cord can be used to repair damaged arteries. In this study, we used an animal model with pathological changes that mimics artery wall damage caused by stent retrievers in humans. We injected hCB-EPCs to investigate their effect on endothelial hyperplasia and dysfunction during intimal repair. Four groups were established based on the length of reperfusion (3 and 28 days), as well as the presence or absence of hCB-EPC therapy. Damage to the internal carotid artery was evaluated by hematoxylin-eosin and immunohistochemical staining. Stroke volume was not significantly different between non-EPC and EPC groups although EPC treatment alleviated intimal hyperplasia 28 days after intimal damage. Vascular endothelial growth factor (VEGF) and eNOS expression were significantly higher in the EPC-treated group than in the non-EPC group 3 days after intimal damage. In addition, MMP9 and 4HNE expression in the EPC-treated group was significantly lower than in the non-EPC group. Ultimately, this study found that venous transplantation of hCB-EPCs could inhibit neointimal hyperplasia, alleviate endothelial dysfunction, suppress intimal inflammation, and reduce oxidative stress during healing of intimal damage.

Extra-articular location of the three-dimensional mechanical axis in advanced knee osteoarthritis: an upright computed tomography study.

PURPOSE: One of the most widely used benchmarks of lower-limb alignment is the mechanical axis (MA), which passes through the centers of the femoral head and the ankle in the weight-bearing position. However, where the MA passes through three-dimensionally (3D) is unclear. We investigated the MA in 3D (3D-MA) in knee osteoarthritis (OA) using upright computed tomography (CT). MATERIALS AND METHODS: This study included 66 varus OA knees from 38 patients [age 70.0 (64.8-77.0) years; median (interquartile range)]. The 3D-MA was determined using upright CT data and compared among Kellgren-Lawrence (KL) grades. Further, correlations between the 3D-MA and other parameters were evaluated. RESULTS: The 3D-MA was located at 5.3 (1.3-14.4)% medially and 7.1 (0.7-15.3)% posteriorly on the tibial plateau in KL-1, and was translated medioposteriorly with increased KL grade. The 3D-MA in KL-3 [30.6 (22.6-42.6)% medially and 50.9 (45.8-80.2)% posteriorly] and KL-4 [56.7 (48.5-62.9)% medially and 92.3 (50.2-127.1)% posteriorly] was located extra-articularly. The mediolateral position of the 3D-MA correlated with the femorotibial angle [correlation coefficient (CC) = - 0.85, p < 0.001], and the anteroposterior position of the 3D-MA correlated with the knee flexion angle (CC = - 0.93, p < 0.001). CONCLUSION: Our analysis demonstrated that the 3D-MA in low-grade OA knees passes slightly medial and posterior to the knee center, and the 3D-MA is translated medioposteriorly with the progression of knee OA. Further, the 3D-MA is translated medially with varus progression and posteriorly with the progression of knee flexion contracture.

Innsbruck-style Retromandibular Anterior Trans-parotid Approach for Condylar Fractures: A Retrospective Review of 39 Fractures.

The retromandibular anterior trans-parotid (RAT) approach and a triangular-positioned double mini-plate osteosynthesis (TDO) technique have been reported from Innsbruck Medical University. This minimally invasive technique involves direct visualization of the condyle and is associated with lower incidence of facial palsy. Methods: A retrospective review was performed on the RAT approach and TDO technique conducted by a surgeon and team at two hospitals in Tokyo during a period of 3 years and 10 months. Results: This technique was performed on 35 patients with 39 condylar fractures. Sixty-nine percent of cases were due to accidental fall, 17% to traffic accidents, and 9% to sports. Furthermore, 92% cases were condylar base fractures. Nighty-seven percent of cases achieved good occlusion. The mean maximum mouth opening was 49 ± 1.3 mm. Postoperatively, facial palsy developed in three patients (7.7%), and two of them developed Frey syndrome at approximately 2.5 years postoperatively (5.1%). All patients completely recovered within 3 months postoperatively. One case each of salivary fistula, visible scar, and condylar resorption was found (2.6%). No case of massive bleeding during surgery, hematoma, or TMJ pain after surgery was found. Conclusion: This technique could achieve good occlusion with low incidence of complications and could contribute to early social reintegration among patients.

Early Prediction of Response Focused on Tumor Markers in Atezolizumab plus Bevacizumab Therapy for Hepatocellular Carcinoma.

Despite the promising efficacy of atezolizumab plus bevacizumab (atezo/bev), some patients with unresectable hepatocellular carcinoma (HCC) experience disease progression. This retrospective study, which included 154 patients, aimed to evaluate predictors of treatment efficacy of atezo/bev for unresectable HCC. Factors associated with treatment response were examined, focusing on tumor markers. In the high-alpha-fetoprotein (AFP) group (baseline AFP ≥ 20 ng/mL), a decrease in AFP level > 30% was an independent predictor of objective response (odds ratio, 5.517; p = 0.0032). In the low-AFP group (baseline AFP < 20 ng/mL), baseline des-gamma-carboxy prothrombin (DCP) level < 40 mAU/mL was an independent predictor of objective response (odds ratio, 3.978; p = 0.0206). The independent predictors of early progressive disease were an increase in AFP level ≥ 30% at 3 weeks (odds ratio, 4.077; p = 0.0264) and the presence of extrahepatic spread (odds ratio, 3.682; p = 0.0337) in the high-AFP group and up-to-seven criteria, OUT (odds ratio, 15.756; p = 0.0257) in the low-AFP group. In atezo/bev therapy, focusing on early AFP changes, baseline DCP, and tumor burden of up-to-seven criteria are useful in predicting response to treatment.

A Unique Case of Sarcoid-associated Myelopathy Accompanied by Lung Cancer.

The differential diagnosis of myelopathy in patients with malignancies may be challenging, as a spinal biopsy is not always applicable. A 66-year-old woman who had shown transient double vision and nausea developed spasticity and impaired deep sensation in both feet. Magnetic resonance imaging showed abnormal gadolinium enhancement of the brainstem, spinal meninges, and nerve root. Cerebrospinal fluid (CSF) revealed mild pleocytosis and elevated protein and decreased glucose levels, although CSF cytology was normal. Lung carcinoma was simultaneously detected, and noncaseating granuloma was detected from the hilar and axillary lymph nodes, so she was diagnosed with sarcoid-associated myelopathy. Her symptoms were kept stable by intravenous methylprednisolone, oral prednisolone, and methotrexate. This is the first case of sarcoid-associated myelopathy accompanied by lung cancer, suggesting the importance of clinical course, repetitive CSF cytology, and a biopsy of the lymph nodes to distinguish sarcoid-associated myelopathy from meningeal metastasis in patients with malignancies.

Simultaneous bilateral quadriceps tendon rupture in a healthy young male: a case report.

BACKGROUND: Simultaneous bilateral quadriceps tendon rupture is rare, particularly in young individuals with no prior medical history. We present the case of a young man who presented with bilateral quadriceps tendon rupture. CASE PRESENTATION: A 27-year-old Japanese man missed a step while descending a flight of stairs, stumbled, and became aware of severe pain in both knees. He had no past medical history, but was severely obese, with a body mass index of 43.7 kg/m2 (height 177 cm, weight 137 kg). Five days after injury, he was referred to our hospital for examination and treatment. Bilateral quadriceps tendon rupture was diagnosed based on magnetic resonance imaging, and quadriceps tendon repair with suture anchor was performed on both knees 14 days after injury. The postoperative rehabilitation protocol was to immobilize both knees in extension for 2 weeks, then to gradually proceed with weight-bearing and gait training using hinged knee braces. Both knees obtained a range of motion from 0° to 130° without any extension lag by 3 months postoperatively. One year postoperatively, tenderness was evident at the suture anchor in the right knee. That suture anchor was therefore removed in a second operation, and histological evaluation of the tendon of the right knee revealed no pathological changes. As of 19 months after the primary surgery, the patient showed a range of motion from 0° to 140° in both knees, did not complain of any disability, and had fully returned to normal daily activities. CONCLUSIONS: We experienced simultaneous bilateral quadriceps tendon rupture in a 27-year-old man with no past medical history other than obesity. Suture anchor repair was performed for both quadriceps tendon ruptures and achieved a favorable postoperative outcome.

A case of Behçet's-like disease associated with trisomy 8-positive myelodysplastic syndrome carrying MEFV E148Q variant presented with periodic fever.

Behçet's-like disease, which incompletely fulfils the criteria of Behçet's disease, is often associated with trisomy 8-positive myelodysplastic syndrome (MDS). We report a case of an 82-year-old man with these conditions carrying the E148Q variant of MEFV gene who presented with periodic fever. The patient presented with joint pain, muscle pain, and episodes of periodic fever every 2 weeks for the past 3 months. On admission, painful erythema and fever were observed. Colonoscopy revealed erosion in the caecum and ascending colon. The patient had bicytopenia, and a bone marrow biopsy showed findings compatible with trisomy 8-positive unclassifiable MDS. Because the patient incompletely fulfilled the criteria for Behçet's disease, he was diagnosed with Behçet's-like disease associated with trisomy 8-positive MDS. Positron emission tomography-computed tomography performed during the fever revealed multiple muscle lesions consistent with the sites of pain. To examine the cause of the periodic fever attacks, MEFV gene was analysed, and the results revealed an E148Q variant. Steroids were ineffective against periodic fever attacks. A daily dose of 0.5 mg colchicine was prescribed, but the effect was minimal, probably, because of the insufficient dose due to renal dysfunction. Based on the diagnosis of atypical familial Mediterranean fever, canakinumab was added, which partially mitigated the periodic fever. This case suggests the importance of ruling out MDS when physicians see an elderly patient who present with Behçet's-like disease. Although the significance of the E148Q variant in the pathogenesis of periodic fever remains controversial, it may act as a disease modifier in accordance with trisomy 8-positive MDS.

Clinical Results of Surgical Treatment for Comminuted Radial Head and Neck Fracture: Headless Compression Screws Versus Plate Fixation.

Background: We surgically treated comminuted radial head and neck fractures using headless compression screws, including multiple screws for the radial head and a single oblique screw for the radial neck. This study aimed to compare the clinical and radiological results for comminuted radial head and neck fractures between surgery using headless compression screws with a single oblique screw for the radial neck, our new procedure, and a plate system precontoured to the proximal radius. Methods: This retrospective study included 23 patients (11 and 12 in the screw and plate groups, respectively). The fractures were type 3 according to the Mason-Johnston classification modified by Broberg and Morrey. Clinical outcomes analyzed included the motion range of the elbow and forearm, Mayo Elbow Performance Score, and radiological assessments. In addition, postoperative complications were also investigated. The average follow-up was 18 months. Results: The bone union was achieved in all the patients, and there were no significant differences in clinical outcomes and radiological assessments except forearm supination (p = 0.02). Furthermore, additional surgical procedures were performed in one and five patients in the screw and plate groups, respectively (p = 0.16). Posterior nerve palsy was observed in two patients in the plate group. Complications were observed in one and six patients in the screw and plate groups, respectively (p = 0.07). Conclusion: Both surgical procedures achieved good clinical and radiological outcomes with bone and ligament injury repair. The screw group had a greater range of forearm supination than the plate group.

A young female case of asymptomatic immune-mediated necrotizing myopathy: a potential diagnostic option of antibody testing for rhabdomyolysis.

Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) immune-mediated necrotizing myopathy (IMNM) is a neuromuscular disorder that presents muscle weakness in proximal extremities and/or the trunk with an elevation of creatine kinase (CK). Young and asymptomatic anti-HMGCR IMNM patients are very rare and a treatment regimen has not been established. The present case, a 17-year-old woman without any muscular symptoms, only showed hyperCKemia that was detected by chance. After close examinations, including a muscle biopsy and antibody search, she was diagnosed as anti-HMGCR IMNM, and initial treatment with methotrexate and continuous intravenous immunoglobulin seemed to be effective. The present case is the unusually young asymptomatic case of anti-HMGCR IMNM. The diagnosis was successfully made, leading to the early introduction of a treatment. Given the course of this case, we believe that the preceding antibody testing is one of the diagnostic option for rhabdomyolysis.

A combination of liver stiffness and international normalized ratio is an ideal prognostic predictor of portosystemic shunt occlusion in patients with portal hypertension.

BACKGROUND: We previously reported liver stiffness (LS) as a prognostic predictor of portosystemic shunt (PSS) occlusion. This study aims to reinvestigate the predictive factors of the model for end-stage liver disease-sodium (MELD-Na) score amelioration following balloon-occluded retrograde transvenous obliteration (BRTO) and to evaluate the postoperative prognoses of patients with portal hypertension by using newly identified factors. METHODS: Seventy-five patients who underwent BRTO between 2008 and 2021 were retrospectively enrolled. The MELD-Na scores were calculated preoperatively and one month postoperatively. We monitored long-term outcomes and analyzed postoperative survival. RESULTS: At one month postoperatively, the MELD-Na score decreased in 46 (61.3%) patients. Univariate analyses revealed a significant association of the score amelioration with nine factors, including lower LS levels and a higher international normalized ratio (INR). A multivariate logistic regression analysis with receiver operating characteristic curve analyses identified preoperative LS levels and INR as significant independent predictors of the postoperative MELD-Na score amelioration, with optimal cutoffs of 28.1 kPa and 1.06, respectively. The combination of LS < 28.1 kPa and INR ≥ 1.06 showed a sensitivity and specificity of 84.8% and 75.9% for the prediction of the score amelioration, respectively. For the propensity score model, we matched 24 patients with similar age, sex, MELD-Na score, and concomitant hepatocellular carcinoma. Kaplan-Meier analysis determined significantly higher cumulative survival rates in patients with LS < 28.1 kPa and INR ≥ 1.06 than in other populations. CONCLUSIONS: A combination of LS and INR can predict the MELD-Na score amelioration and prognosis improvement following PSS occlusion.
