OBJECTIVES@#To analyze the effect of hyperlipoproteinemia (α) on immediate expansion after coronary stent implantation guided by intravascular ultrasound (IVUS).@*METHODS@#A total of 160 patients (175 lesions) with coronary heart disease diagnosed by coronary artery angiography, who were performed percutaneous intervention guided by IVUS in the Department of Cardiology, Third Xiangya Hospital, Central South University, were enrolled retrospectively.According to the concentration of lipoproteina, the patients were divided into 2 groups: a hyperlipoproteinemia (α) group and a control group. Cardiac ejection fraction was measured with echocardiography. Logistic regression was used to analyze the influential factors for hyperlipoproteinemia (α). The target vessel was examined by IVUS to analyze the immediate expansion effect of hyperlipoproteinemia (α) after stent implantation.@*RESULTS@#The mean stent expansion index, lesion length, stent number, stent symmetry index and posterior balloon diameter were (94.73±18.9)%, (52.92±29.1) mm, (2.11±0.85), (83.62±13.07)%, and (9.46±2.00) mm in the hyperlipoproteinemia (α) group, respectively. Compared with the control group, there were significantly difference (all @*CONCLUSIONS@#Hyperlipoproteinemia (α) appears to be a predictor of stent underexpansion, and the decreased creatinine clearance rate is an independent risk factor for hyperlipoproteinemia (α).

The practice of regional anesthesia is in a state of progressive evolution, mainly due to the advent of ultrasound as an anesthesiologist's instrument. Alternative techniques for postoperative analgesia of abdominal surgeries, such as transversus abdominis plane block, oblique subcostal transversus abdominis plane block, rectus abdominis muscle sheath block, ilioinguinal and iliohypogastric nerve block, and quadratus lumborum plane block, have proven useful, with good analgesic efficacy, especially when neuroaxial techniques (spinal anesthesia or epidural anesthesia) are not possible. This review discusses such blockades in detail, including the anatomical principles, indications, techniques, and potential complications.

ABSTRACT Purpose To investigate the course of anxiety and depression before and after transrectal ultrasound-guided prostate biopsy (TRUS-Bx) and in the postoperative 1st month when the histopathological biopsy result was obtained. Methods In between June 2017- January 2019, 204 patients who underwent TRUS-Bx and completed the questionnaires assessing anxiety and depression were included in the study. Questionnaires were completed immediately before the biopsy, immediately after the biopsy and at the end of the first month when the histopathological biopsy results were given. State-Trait Anxiety Inventory (STAI), Hospital Anxiety and Depression Scale (HADS) and perceived stress scale (PSS) forms were used to assess anxiety and depression. After the histopathological examination patients were divided into two groups as patients without cancer (Group 1) and with cancer (Group 2). Data was compared between the groups. Results PSA level was negatively correlated with STAI TX-1 scores of the patients immediately after TRUS-Bx, whereas it was positively correlated with STAI TX-1 and TX-2 30 days after the TRUS-Bx. PSA level was positively correlated with HADS-A and HADS-D scores immediately before and 30 days after TRUS-Bx. Biopsy results showed a significant difference in 30 day post-biopsy related data. STAI TX-1, STAI TX-2, HADS-A, HADS-D and PSS scores were higher in Group 2 compared with Group 1. Conclusions Pre-biopsy anxiety disappeared after bx, but there was a significant increase in anxiety and depression in patients after the diagnosis of malignancy. Patients were seriously concerned about the diagnosis of prostate cancer.

IIntroduction: Central venous catheterization is a common procedure in intensive care units (ICU). The use of ultrasound (US) to guide catheterization offers advantages, allowing for an accurate topographic image of the vessel, reducing complications as well as time and number of punctures. Objective: To determine whether the use of US for the placement of central venous catheters (CVCs) may decrease the number of punctures and achieve successful catheterization. Patients and methods: A descriptive, prospective study was conducted of CVCs placed by US-guided puncture at a general ICU of Hospital de Pediatría Juan P. Garrahan between 2018 and 2019. Patients from 1 month to 18 years of age who required US-guided placement of a CVC were included. A p< 0.05 was considered significant. Results: The internal jugular vein (IJV) was used in 66 (43.5%) and the femoral vein (FV) in 86 patients (56.5%). Overall, in 86 (56.5%) CVC were inserted on the first attempt and 66 (43.5%) required more than one attempt. Insertions into the VYI were successful on the first attempt in 46 (53.5%) patients and 20 (30.3%) patients required more than one attempt, p 0.004; OR 0.37 (95% CI 0.18-0.78). In patients <6 months CVCs placed in the IJV had a lower risk of requiring more than one attempt compared to those in which the FV was chosen, p 0.0026 OR 0.31 (95% CI 0.12 -0.75). Complications occurred in 5.2%; no procedure-related mortality was observed. Conclusions: US-guided insertion of CVC was safe and significantly successful on the first attempt when the vessel of choice was the IJV, especially in patients < 6 months (AU)

SUMMARY OBJECTIVE: To evaluate the value of EBUS-TBNA in the diagnosis of lung and mediastinal lesions. METHODS: Prospective cohort study that included 52 patients during a 2-year period (2016 to 2018) who underwent EBUS-TBNA. RESULTS: Among the 52 individuals submitted to the procedure, 22 (42.31%) patients were diagnosed with locally advanced lung cancer (N2 or N3 lymph node involvement). EBUS-TBNA confirmed the diagnosis of metastases from other extrathoracic tumors in the mediastinum or lung in 5 patients (9.61%), confirmed small cell lung cancer in 3 patients (5.76%), mediastinal sarcoidosis in 1 patient (1.92%), and reactive mediastinal lymph node in 8 patients (15.38%); insufficient results were found for 3 patients (5.76%). Based on these results, EBUS-TBNA avoided further subsequent surgical procedures in 39 of 52 patients (75%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 86%, 100%, 100%, 77%, and 90%, respectively. No major complications were observed. CONCLUSIONS: EBUS-TBNA is a safe, effective, and valuable method. This technique can significantly reduce the rate of subsequent surgical procedures required for the diagnosis of lung and mediastinal lesions.

RESUMO OBJETIVO: Avaliar a importância da ecoendoscopia endobrônquica com punção por agulha fina (Ebus-TBNA) no diagnóstico das lesões pulmonares e mediastinais. MÉTODOS: Estudo prospectivo e do tipo coorte, no qual foram incluídos 52 pacientes, durante o período de dois anos (2016 a 2018), submetidos ao procedimento de Ebus-TBNA. RESULTADOS: Do total de 52 indivíduos submetidos ao procedimento, 22 (42,31%) pacientes foram diagnosticados com neoplasia pulmonar localmente avançada (N2 ou N3). O método confirmou o diagnóstico de metástases de outros tumores extratorácicos no mediastino ou pulmão em cinco pacientes (9,61%), três pacientes (5,76%) com carcinoma de pequenas células, um paciente (1,92%) com sarcoidose, oito pacientes (15,38%) com linfonodomegalias reacionais/inflamatórias e resultado insuficiente em três pacientes (5,76%). O Ebus-TBNA evitou a realização de outros procedimentos cirúrgicos subsequentes em 39 de 52 (75%) pacientes. Foram calculados os valores de sensibilidade de 86%, especificidade de 100%, valor preditivo positivo de 100%, valor preditivo negativo de 77% e acurácia de 90%. Não foram observadas complicações maiores pelo método neste estudo. CONCLUSÃO: O Ebus-TBNA é um método seguro, eficaz e de relevante importância. Este exame pode reduzir significativamente o número de procedimentos invasivos subsequentes necessários para o diagnóstico das lesões pulmonares e mediastinais.

INTRODUCCIÓN: El tromboembolismo pulmonar (TEP) es una causa frecuente de morbimortalidad cardiovascular y la trombolisis local asistida por ultrasonido (TLUS) constituye una alternativa de tratamiento validada para pacientes de riesgo intermedio. No existen reportes del uso de esta tecnología en el ámbito nacional. MÉTODOS: Análisis descriptivo, prospectivo, sobre una serie de pacientes con TEP agudo, de riesgo intermedio, tratados en forma percutánea con trombolisis local asistida por catéter de ultrasonido terapéutico (EKOSonic®). Se analiza la eficacia y seguridad del procedimiento mediante variables clínicas, hemodinámicas y radiológicas, así como desenlaces intra hospitalarios. Se reporta, además, el seguimiento a 30 días. RESULTADOS: Entre Junio de 2019 y Marzo de 2020, 4 pacientes con TEP de riesgo intermedio fueron tratados con esta técnica. El score PESI (Pulmonary Embolism severity Index) promedio era de 79,5 + 6,1. Dos pacientes requirieron la instalación de 2 catéteres para efectuar terapia bilateral. Se observó una reducción promedio en la presión sistólica de arteria pulmonar de 29% y en 3 de los 4 enfermos se logró revertir la dilatación ventricular derecha presente al ingreso. La carga trombótica se redujo en un 20% medido por score CTOI. No hubo complicaciones intraoperatorias ni intrahospitalarias asociadas a la intervención. CONCLUSIONES: En esta serie inicial, el uso de la trombolisis local con catéter de ultrasonido en pacientes con TEP de riesgo intermedio fue segura y efectiva. Los resultados perioperatorios y a 30 días fueron comparables a los descritos en experiencias internacionales; sin embargo, aún se requieren de estudios con mayor número de pacientes para confirmar los beneficios de esta técnica en nuestro medio.

BACKGROUND: Pulmonary thromboembolism (PE) is a common cause of cardiovascular morbidity and mortality and local ultrasound-assisted thrombolysis (USAT) is a validated alternative treatment for intermediate-risk patients. There are no reports on the use of this technology in our country. METHODS: Prospective series of patients with acute, intermediate-risk PE treated percutaneously with therapeutic ultrasound catheter-assisted local thrombolysis (EKOSonic®). The efficacy and safety of the procedure were analyzed using clinical, hemodynamic, and radiological variables, as well as intra-hospital outcomes. The 30-day follow-up is also reported. RESULTS: between June 2019 and March 2020, a total of 4 patients with intermediate-risk PE were treated with this technique. The average PESI score was 79.5 + 6.1. Two out of 4 patients required the use of 2 catheters for bilateral therapy. The average reduction in systolic pressure of the pulmonary artery was 29% and 3 patients reversed the right ventricular dilation present at admission. The thrombotic burden was reduced by 20% according to the Computed Tomography Obstruction Index (CTOI). There were no intraoperative or in hospital complications associated with the intervention. CONCLUSION: In this initial series, the use of local thrombolysis with an ultrasound catheter in patients with intermediate-risk PE was safe and effective. The perioperative and 30-day outcomes were similar to those previously reported in international series. However, larger randomized trials are needed to confirm this potential benefit.

Abstract Introduction: Laryngeal lesions are usually evaluated by microlaryngoscopy/direct laryngoscopy under anaesthesia for disease mapping and tissue diagnosis. However patients with anticipated airway compromise due to laryngeal mass may require either a protective tracheotomy or emergency tracheotomy to secure the airway. To minimise risk of unplanned tracheotomy and expedite the diagnosis we performed ultrasound-guided transcutaneous fine needle aspiration cytology. Objective: To evaluate the feasibility and performance of ultrasound-guided transcutaneous fine needle aspiration cytology of suspicious/recurrent laryngo-hypopharyngeal masses. Methods: Fine needle aspiration cytology was performed under ultrasound guidance. Twenty- four patients were recruited, of which 17 had a pure laryngeal lesion; 6 patients had laryngo-pharyngeal, and one patient had a base tongue lesion with supra-glottis extension. Results: Out of 24 patients, 21 had positive cytology for squamous cell carcinoma, 2 patients had non-diagnostic cytology (atypical cells) and the other had inadequate tissue for definitive diagnosis. Patients with negative and inconclusive cytology underwent direct laryngoscopy biopsy, which was positive for squamous malignancy. All patients tolerated the procedure well and no adverse events were noted. Conclusion: Although direct laryngoscopy remains the standard of care in evaluation of laryngo-hypopharyngeal lesions, this pilot study has shown that ultrasound-guided transcutaneous fine needle aspiration cytology was feasible as an out-patient procedure, employing safe and sensitive technique enabling rapid diagnosis and avoiding the need for direct laryngoscopy under GA for tissue diagnosis.

Resumo Introdução: As lesões laríngeas são geralmente avaliadas por microlaringoscopia/laringoscopia direta sob anestesia para mapeamento da doença e diagnóstico tecidual. No entanto, em pacientes com comprometimento prévio das vias aéreas devido à lesão laríngea, pode ser necessária uma traqueostomia protetora ou traqueostomia de emergência para assegurar as vias aéreas. Para minimizar o risco de uma traqueostomia não planejada e facilitar o diagnóstico, realizamos punção aspirativa por agulha fina guiada por ultrassonografia transcutânea. Objetivo: Avaliar a viabilidade e o desempenho da punção aspirativa por agulha fina guiada por ultrassonografia transcutânea em lesões laríngeo-hipofaríngeas suspeitas/recorrentes. Método: A punção aspirativa por agulha fina foi realizada sob orientação ultrassonográfica. Foram recrutados 24 pacientes, 17 com lesão laríngea apenas, 6 com lesão laríngeo-faríngea e um com lesão na base da língua com extensão supraglótica. Resultados: Dos 24 pacientes, 21 apresentaram citologia positiva para carcinoma espinocelular, 2 citologia não diagnóstica (células atípicas) e o outro tecido inadequado para o diagnóstico definitivo. Os pacientes com citologia negativa e inconclusiva foram submetidos à biópsia através de laringoscopia direta, que foi positiva para lesão maligna espinocelular. Todos os pacientes toleraram bem o procedimento e nenhum evento adverso foi observado. Conclusão: Embora a laringoscopia direta continue a ser o padrão de cuidado na avaliação das lesões laríngeo-hipofaríngeas, este estudo piloto demonstrou que a punção aspirativa por agulha fina guiada por ultrassonografia transcutânea é uma técnica viável, ambulatorial, segura e sensível, permite rápido diagnóstico e evita a necessidade de laringoscopia direta sob anestesia geral para diagnóstico tecidual.

ABSTRACT Objectives: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. Materials and Methods: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofl oxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofl oxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. Results: Mean age was 62.38±7.30 (47-75), and the mean prostate volume was 43.17±15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the first biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). Conclusions: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

Accurate coronary measurements are important in guiding percutaneous coronary intervention. Intravascular ultrasound is a widely accepted diagnostic modality for coronary measurement before percutaneous coronary intervention. The spatial resolution of optical coherence tomography is 10 times larger than that of intravascular ultrasound. The objective of the study was to compare quantitative and qualitative parameters of frequency domain optical coherence tomography (FDOCT) with those of intravascular ultrasound and coronary angiography in patients with acute myocardial infarction. Diagnostic parameters of coronary angiography, intravascular ultrasound, and FDOCT of 250 patients with coronary artery disease who required admission diagnosis were included in the analyses. Minimum lumen diameter detected by FDOCT was larger than that detected by quantitative coronary angiography (2.11±0.1 vs 1.89±0.09 mm, P<0.0001, q=34.67) but smaller than that detected by intravascular ultrasound (2.11±0.1 vs 2.19±0.11 mm, P<0.0001, q=12.61). Minimum lumen area detected by FDOCT was smaller than that detected by intravascular ultrasound (3.41±0.01 vs 3.69±0.01 mm2, P<0.0001). FDOCT detected higher numbers of thrombus, tissue protrusion, dissection, and incomplete stent apposition than those detected by intravascular ultrasound (P<0.0001 for all). More accurate and sensitive results of the coronary lumen can be detected by FDOCT than coronary angiography and intravascular ultrasound (level of evidence: III).

This study aims to compare the prostate cancer detection rate between magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) cognitive fusion targeted biopsy and systematic biopsy. A total of 614 patients who underwent transrectal prostate biopsy during 2016-2018 with multiparametric magnetic resonance imaging (mpMRI) were included. All patients with a PI-RADS V2 score ≥ 3 accepted both targeted biopsy and systematic biopsy, and those with a PI-RADS V2 score ≤ 2 only accepted systematic biopsy. Overall prostate cancer detection rate between the two biopsies was compared. MRI-TRUS cognitive fusion targeted biopsy identified 342 cases (75.7%) of prostate cancer while systematic biopsy identified 358 cases (79.2%). There was no significant difference in the detection rate between the two groups ( = 1.621, = 0.203). Targeted biopsy had significant fewer biopsy cores compared with systematic biopsy, reducing (9.3 ± 0.11) cores ( < 0.001) in average. Targeted biopsy had about 10.8% ( < 0.001) more tumor tissues in positive cores compared with systematic biopsy. The results show that both MRI-TRUS cognitive fusion targeted biopsy and systematic biopsy have good detection rate on prostate cancer. Cognitive targeted biopsy may reduce biopsy cores and provide more tumor tissues in positive cores.

OBJECTIVE@#To analyze the accuracy and positive rate of ultrasound-guided fine-needle aspiration (US-FNA) cytology for detecting suspected thyroid cancer nodules of different sizes.@*METHODS@#A total of 591 patients with 594 suspected malignant thyroid nodules received examinations with US-FNA cytology. Based on their size, the nodules were divided into group I (4-5 mm), group II (6-10 mm), group III (>10 mm). With the results of pathology as the standard, we analyzed the results of US-FNA cytology for detecting thyroid carcinoma in terms of its accuracy, indeterminate rate, positive predictive value and negative predictive value for nodules of different sizes.@*RESULTS@#The positive rates in group I, group II and group III were 39.2% (40/102), 48.2% (172/357) and 65.2% (88/135), respectively, similar between groups I and II (=0.107) and differed significantly between groups I and III (=0.000) and between groups II and III (=0.001). The accuracy, indeterminate rate, positive predictive value and negative predictive value in the 3 groups were 95.5% (21/22), 97.1% (100/103), and 94.4% (51/54); 2.9% (3/102), 2.8% (10/357), and 1.5% (2/135); 100%, 100%, and 98%; 66.7%, 57.1%, and 33.3%, respectively, showing no significant differences among the 3 groups.@*CONCLUSIONS@#The size of the thyroid nodules can affect the positive rate but does not have significant effects on the accuracy, indeterminate rate, positive predictive value or negative predictive value of US-FNA cytology.

SUMMARY OBJECTIVE The aim of the current study was to compare the efficacy of two different techniques for blocking chest nerves during video-assisted thoracic surgery (VATS) under spontaneous-ventilating anesthesia. METHODS One hundred patients were recruited in this study and divided into two groups. The first, P group, underwent the TPVB approach; the second, I group, underwent the ICNB approach. Then, the rate of clinical efficacy, duration of the block procedure, and its complications were recorded for comparison of the effect of the two approaches. RESULTS No difference was found in the clinical effect of chest nerve blocks between the two groups. Two patients in the ICNB group were converted to general anesthesia due to severe mediastinal flutter (grade three). The number of patients who had grade one mediastinal flutter in the TPVB group was significantly higher than in the ICNB group. Vascular puncture was detected in four patients in the ICNB group and in one patient in the TPVB group. No other complications were observed. CONCLUSIONS No difference was found regarding the clinical efficacy in the two groups. However, ultrasound-guided TPVB was superior to ultrasound-guided ICBN during VATS for pulmonary lobectomy under spontaneous-ventilating anesthesia. Additionally, vascular puncture should receive more attention.

RESUMO OBJETIVO O objetivo do presente estudo é comparar a eficácia de duas técnicas diferentes para o bloqueio nervoso torácico durante cirurgia torácica vídeo-assistida (CTVA) e anestesia com ventilação espontânea. METODOLOGIA Cem pacientes foram incluídos no estudo e divididos em dois grupos. Em um (grupo P), foi utilizada a abordagem de BPVT e no outro (grupo I), a abordagem de BIC. Então, a taxa de eficácia clínica, duração do procedimento de bloqueio e suas complicações foram registradas para a comparação do efeito das duas abordagens. RESULTADOS Nenhuma diferença foi observada no efeito clínico do bloqueio nervoso torácico entre os dois grupos. Dois pacientes no grupo de BIC foram convertidos para anestesia geral devido a fibrilação mediastinal grave (grau três). O número de pacientes com fibrilação mediastinal de grau um no grupo de BPVT foi significativamente maior do que no grupo de BIC. Perfuração vascular foi detectada em quatro pacientes do grupo de BIC e em um do grupo de BPVT. Não foram observadas outras complicações. CONCLUSÃO Não houve diferença de eficácia clínica entre os dois grupos. No entanto, BPVT guiado por ultrassom foi superior ao BIC guiado por ultrassom durante CTVA para lobectomia pulmonar com anestesia em ventilação espontânea. Além disso, deve-se prestar mais atenção quanto à perfuração vascular.

ABSTRACT Introduction: simulation based teaching is a powerful tool in medical education, allowing hands on practice under a controlled environment and with repeated maneuvers. Central venous access venipuncture is one of the most frequent procedures carried out in the hospital setting, due to its various clinical indications and, when performed with the help of ultrasonography, the risk of adverse events is minimized. Aim: to develop, to describe and to test a porcine model that simulates the central venous access puncture aided by ultrasonography. Method: a low cost porcine model was developed to train medical students and residents on central venous access guided by ultrasonography. Both students and medical residents underwent a theoretical training regarding the model, followed by a hands-on training session. Afterwards, the participants assessed the model by answering a questionnaire. Results: there were 51 participants. The average score regarding the similarity between the model and the human anatomy was 9.15. When the characteristics were separately assessed, the mean scores regarding the similarity of the vessels, anatomic disposition and ultrasonographic characteristics as well as the venipuncture were, respectively, 9.27; 9.31; 9.54 and 8.86. Conclusion: The model was approved and considered appropriate for the training of central venous venipuncture by all the participants. Furthermore, it is a low cost, simple and reproducible model, that presents high similarity with the human anatomy. Therefore, it may be used as an aid to train people on ultrasonography guided central venous access.

OBJECTIVE@#To investigate the effect of ultrasound guided reduction and exploration of ulnar nerve position and percutaneous crossed pin fixation for the treatment of displaced supracondylar fracture of the humerus in children.@*METHODS@#The clinical data of 45 patients with displaced supracondylar fracture of humerus from December 2017 to December 2018 were analyzed retrospectively, including 26 boys and 19 girls, ranging in age from 1 year and 3 months to 11 years and 4 months, with an average of 7.6 years old;44 cases of crashing injury, 1 case of falling injury;29 cases on the left side, 16 cases on the right side;12 patients classified to Gartland typeⅡand 33 patients classified to Gartlandtype Ⅲ. The operation was performed from 4 h to 7 d after injury, with an average of 2.5 d. There were no neurological and vascular injuries occurred in the children. Ultrasound was used to guide the fracture reduction of the child, and the cross-needle was fixed. In the medial needle insertion, the ulnar nerve position was detected by ultrasound to avoid damage to the ulnar nerve. The ulnar nerve state was observed during operation. The clinical function evaluation criteria of Flynn was used at the latest follow-up. The evaluation criteria was used to evaluate the functional and aesthetic characteristics of the elbow joints of the children, and to observe the complications such as ulnar nerve injury after operation.@*RESULTS@#Ultrasound was used to detect the fracture from the medial side of the elbow, the lateral aspect of the elbow and the sagittal plane of the elbow. The position of the ulnar nerve could be clearly explored to avoid ulnar nerve injury when the needle was inserted inside. All children were followed up, and the duration ranged from 6 to 12 months, with an average of 9 months. None of the patients had a loss of repositioning and the fractures healed. The healing time ranged from 4 to 6 weeks, with an average of 5 weeks. At the latest follow-up, according to Flynn's evaluation criteria:compared with the healthy side, 41 patients with flexion and extension limitation were 0° to 5°, clinically evaluated as excellent;3 patients with flexion and extension limitation were 6° to 10°, clinically evaluated as good;1 patient with flexion and extension limitation was 11° to 15°, clinically evaluated as acceptable. Compared with the healthy side, 40 patients lost 0° to 5°of the angle, and 5 patients lost 6° to 10°of the angle. There were no complications such as ulnar nerve injury and cubitus varus.@*CONCLUSION@#Although ultrasound-guided treatment of displaced supracondylar fracture of the humerus in children has higher requirements for the operator at present, because of its advantages of clear development, portability, effectiveness and no impact on health, it could clearly explorethe fracture situation during the operation, guide the reduction of the fracture, and accurately show the position of the ulnar nerve, effectively improve the safety of the medial puncture, so as to minimize the complications The occurrence of the disease. Therefore, the treatment of displaced supracondylar fracture of humerus with ultrasound-guided manual reduction and percutaneous cross needle fixation is effective and worthy of further promotion.
