Methods 194 patients with CHD and 86 nonCHD patients were selected through coronary angiography in patients with essential hypertension. CHD group was divided into three subgroups including a single branch, doublebranch and multivessel disease. Intimamedia thickness (IMT) of carotid artery and carotid bifurcation, grade score, Crouse score, serum uric acid concentrations were detected in patients with coronary heart disease and control group. Results IMT of carotid artery and carotid bifurcation, grade score,crouse score, serum uric acid concentrations were higher in CHD group than that in control group, and the difference was statistically significant. In the CHD group, ultrasound parameters of carotid artery and serum uric acid increased with the increase in branch lesions (Plt;005 or 001). Conclusions Carotid IMT, grade score, Crouse score, serum uric acid concentration relate to coronary heart disease, which is an independent risk factor for coronary heart disease, respectively.
Crohn’s disease (CD) is a chronic, remitting and segmental inflammatory disease of the gastrointestinal tract, radiological examinations play critical roles in the diagnosis of CD. The common radiological examinations include ultrasound examinations of intestine, computed tomography enterography (CTE), and magnetic resonance enterography (MRE) in clinic. The application of CTE and MRE is limited because of radiation exposure or higher costs. The ultrasound examinations of intestine including conventional intestinal ultrasound, ultrasonic elastography, and contrast-enhanced ultrasound have been studied because of the advantages of non-invasiveness and convenience. The accuracy of the intestinal ultrasound has been already partially validated in assisting diagnosis and evaluating the disease activity and location in CD patients. This review aims at summarizing the diagnostic potency and prospect of the application of ultrasound examinations of intestine in CD patients.
ObjectiveTo evaluate the clinical efficacy of surgical intervention combined with endoscopic ultrasound-guided transluminal drainage in the treatment of infected pancreatic necrosis (IPN). MethodsA retrospective, historical control study was conducted. A total of 98 patients with acute pancreatitis (AP) complicated with IPN who met the inclusion and exclusion criteria and were admitted to the Third People’s Hospital of Chengdu from June 2016 to January 2023 were selected as the research objects. The endoscopic ultrasound-guided transluminal drainage was carried out in our hospital in June 2020. In this study, patients treated before May 2020 were divided into the non-EUS group (52 cases), and patients treated after June 2020 were divided into the EUS group (46 cases). The baseline data, surgical intervention, length of hospital stay, length of intensive care unit (ICU) stay, infection time, incidence of multiple organ dysfunction syndrome (MODS), survival situation, short-term and long-term complications, and other indicators were compared between the two groups. ResultsThe number of percutaneous catheter drainage (PCD, 1.0 vs. 1.0), the number of PCD drainage tube (1.0 vs. 2.0), the number of retroperitoneal debridement drainage (1.0 vs. 2.0), the total length of hospital stay (42.0 d vs. 45.5 d), the length of ICU stay (11.0 d vs. 14.0 d), the length of infection time (10.5 d vs. 18.5 d), the incidences of MODS [43.5% (20/46) vs. 67.3% (35/52)] and residual infection [28.3% (13/46) vs.48.1% (25/52)] in the EUS group were shorter (or lower) than those in the non-EUS group (P<0.05); but there were no significant differences in the number of endoscopic pancreatic stent implantation, the number of laparotomy, the number of laparoscopic surgery, and the incidences of abdominal bleeding, gastrointestinal fistula, gastrointestinal obstruction, chronic pancreatic fistula, chronic pancreatitis and incisional hernia between the two groups (P>0.05). ConclusionFor patients with AP complicated with IPN, surgical intervention combined with endoscopic ultrasound-guided transluminal drainage can reduce the number of PCD and drainage tube, shorten the total length of hospital stay, the length of ICU stay and infection, as well as reduce the incidences of MODS and residual infection.
Objective To explore the value of pulmonary ultrasound in the evaluation of pulmonary edema and the guidance of pulmonary therapy in patients with acute respiratory distress syndrome (ARDS). Methods Sixty patients with ARDS admitted to the Department of Critical Medicine of Shanghai Seventh People’s Hospital were randomly divided into a lung ultrasound group and a control group, with 30 patients in each group. The gender, age and etiology of patients were collected, and the relevant data were recorded at the time of admission and on the 7th day, including Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) score, Sequential Organ Failure Assessment score (SOFA), white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), extravascular pulmonary water index, oxygenation index, and mechanical ventilation treatment time. Pulmonary ultrasound score was collected in the pulmonary ultrasound group. The 7-day improvement rate, intensive care unit (ICU) hospitalization time and 28 day mortality rate of the two groups were also collected. The value of pulmonary ultrasound in evaluating the severity, treatment process and prognosis of patients, and the correlation between pulmonary ultrasound score and extravascular pulmonary water index were studied. Results There was no significant difference in APACHEⅡ score, SOFA score, oxygenation index, extravascular pulmonary water index, WBC, CRP or PCT between the two groups before and after treatment (all P>0.05). After 7 days of treatment, the two groups improved, and the pulmonary ultrasound group improved more significantly with more shorter mechanical ventilation time, higher 7-day improvement rate, shorter ICU hospitalization time, and lower 28-day mortality rate (all P<0.05). The extravascular pulmonary water index was positively correlated with APACHEⅡ score and SOFA score, and negatively correlated with oxygenation index. The pulmonary ultrasound score was positively correlated with APACHEⅡ, and SOFA score and extravascular pulmonary water index, and negatively correlated with oxygenation index. Conclusions Pulmonary ultrasound can effectively evaluate the severity of ARDS patients, guide the individualized treatment, and predict the prognosis. It can be used as a routine monitoring method for patients with ARDS.
ObjectiveTo explore the value of active surveillance (AS) with ultrasound for papillary thyroid microcarcinoma (PTMC) tumor growth.MethodsA retrospective collection of 196 patients who underwent ultrasound-guided fine-needle aspiration biopsy at West China Hospital of Sichuan University from January 2014 to December 2018 were pathologically diagnosed as PTMC, and no cervical lymph node metastasis was found on ultrasound, and AS was performed. According to the change of the maximum diameter of the nodule, the patients were divided into the maximum diameter increase group, the maximum diameter stable group and the maximum diameter reduction group. According to the nodule volume change, the patients were divided into the volume increase group, the volume stable group and the volume reduction group. The differences in the patients’ gender, age, with Hashimoto’s thyroiditis, follow-up time, tumor size, boundary, shape, echo, aspect ratio, calcifications, multifocality, bilateral involvement, other nodule, surrounding tissues and cervical lymph nodes among the different groups were analyzed in order to clarify the related factors of tumor growth.ResultsOne hundred and ninety-six patients had ultrasound AS time ranging from 6 to 79 months with the median (quartile) time were 16.0 (10.0, 30.0) months. One hundred and seventeen patients (59.7%) were in AS for 6 to 63 months with the median (quartile) time were 13.0. (8.0, 22.0), surgical treatments were performed after termination of AS. Forty-five patients (23.0%) continued to perform AS, 34 patients (17.3%) did not continue to perform AS in West China Hospital of Sichuan University. There was no significant reduction in the maximum diameter and volume of the nodules in all cases. Among them, 9 cases (4.6%) had an increase in the maximum diameter of the nodules, and 187 cases (95.4%) had a stable maximum diameter. Forty cases (20.4%) had an increase in the volume of the nodules, and 156 cases (79.6%) had a stable volume of the nodules. Comparison of the maximum diameter change of nodules between the two groups, there was a significant difference in the age of patients (P<0.05). Comparison of the maximum volume change between the two groups, there were significant differences in age, follow-up time and initial nodule volume (P<0.05). Logistic regression analysis showed that younger age was an independent risk factor for PTMC nodule growth [OR＝0.638, 95%CI (0.601, 0.675), P＝0.015].ConclusionsYounger age is a risk factor for PTMC tumor growth. We should adopt a more active monitoring program for younger patients. The increase of PTMC tumor volume can be more easily monitored than the increase of its maximum diameter, so it can be used as an indicator to predict nodule growth at an earlier stage in AS.
ObjectiveTo investigate the clinical value of cervical vascular color Doppler ultrasound for dignosis of nonrecurrent laryngeal nerve before thyroid surgery. MethodsThere were 1931 cases of thyroid patients treated between January 2010 to Jule 2014, group these patients according to the results of preoperative chest radiograph examination, the chest radiograph shows abnormal vessels image were group A (45 cases), no abnormalities were group B (1886 cases). Before operaton, made patients of group A to have routine carotid duplex ultrasound to identify whether the right subclavian artery abnormalities. All patients were exposed to conventional methods of recurrent laryngeal nerve during surgery. ResultsThe 45 patients of group A, chest angiography showed 17 cases with right subclavian artery abnormalities, they were confirmed that all the 17 patients were nonrecurrent laryngeal nerve by surgery, no damage cases. The other 28 cases showed a normal right subclavian artery and no cases of nonrecurrent laryngeal nerve. The 1886 patients in group B, surgical exploration found four cases with nonrecurrent laryngeal nerve, injury in 1 case. The 21 patients whose nonrecurrent laryngeal nerve were on the right side, there were no left side with nonrecurrent laryngeal nerve and no co-exist cases of nonrecurrent and recurrent laryngeal nerve. The average exposure time of nonrecurrent laryngeal nerve in patients of group A (17 cases) was significantly shorter than that group B[(4.28±1.08) min vs. (15.50±2.08) min, t=-15.978, P=0.000]. ConclusionsThe cervical vascular color Doppler ultrasound examination before thyroid surgery can be adjuvant used, if there is the right subclavian artery abnormalities, it showes that there is the right side nonrecurrent laryngeal nerve. So as to effectively prevent the damage of nonrecurrent laryngeal nerve during thyroid surgery.
Objective To analyze the safety and effectiveness of ultrasound-guided thoracoscopic atrial septal defect (ASD) closure. Methods We prospectively collected the clinical data of 12 patients with ASD treated by ultrasound-guided thoracoscopic ASD closure in Fuwai Hospital from January to September 2017. The characteristics of the patients' ASD and operation, operation safety and effectiveness, postoperative complications and follow-up results were analyzed. Results Among the 12 patients, 10 were successfully treated with ultrasound-guided thoracoscopic ASD closure. Two patients switched to ASD repair under thoracoscopy-assisted cardiopulmonary bypass. The size of the ASD was 17-40 (27.22±8.97) mm and the size of the occluder was 36 (30-42) mm. The average postoperative length of hospital stay was 6 days. There were no complications such as arrhythmia, bleeding and pericardial effusion after operation. The average follow-up was 6 (3-10) months after the operation. During the follow-up, no Ⅲ-degree conduction block, occluder dislocation, residual shunt or cardiac pericardial effusion was found. Conclusion Ultrasound-guided thoracoscopic ASD closure is a minimally invasive, safe and effective treatment. This technique provides a new minimally invasive surgical option for patients with large defect diameter and poor edge condition.
ObjectiveTo explore the incidence of and relative factors for infectious complications after transrectal prostatic biopsy. MethodsWe retrospectively analyzed the clinical data of 238 patients who underwent prostate puncture biopsy via rectum between January 2008 and December 2013, and analyzed the rate of infectious complications. At the same time, we compared the data of infection group and non-infection group to analyze the risk factors for infection. ResultsAmong the 238 patients, infectious complication was found in 25 cases (10.5%), and there was no significant difference between infection and non-infection group in age and pathological results (P>0.05). However, diabetes history and the increased number of puncture needles may increase the risk of infection (P<0.05). ConclusionThough transrectal prostatic biopsy is considered simple and safe, infectious complications may happen during the application. Reasonable evaluation, adequate preparation before biopsy and appropriate number of puncture needles are recommended to decrease the incidence of infections.
ObjectiveTo compare the effectiveness of ultrasound-guided closed reduction and Kirschner wire fixation for different unstable humeral lateralcondylar fractures of children. Methods The clinical data of 94 children with unstable humeral lateralcondylar fractures admitted to three medical centers between January 2021 and October 2022 were retrospectively analyzed. The children were divided into three groups according to the Song classification and whether the elbow joint was dislocated or not, including 42 cases of Song 4 type (group A), 38 cases of Song 5 type (group B), and 14 cases of elbow joint dislocation (group C). There was no significant difference in gender, age, side, cause of injury, and time from injury to operation among the three groups (P>0.05). All children were treated with ultrasound-guided closed reduction and Kirschner wire fixation. The operation time and complications of the three groups were recorded and compared, and the failure of closed reduction was evaluated by ultrasound. X-ray examination was performed at last follow-up to measure the Baumann angle, condylar angle, carrying angle, and lateral osteophyte of the affected side; the extension, flexion, pronation, and supination range of motion of the affected elbow joint were measured; the function of the elbow joint was evaluated by Mayo score. ResultsThe operation time in group A was significantly longer than that in groups B and C (P<0.05). There were 7, 2, and 5 cases of closed reduction failure in groups A, B, and C, respectively, and there was no significant difference in the incidence of the closed reduction failure (P>0.05). All patients were followed up 6-28 months, with an average of 15.7 months. There was no significant difference in the follow-up time among the three groups (P>0.05). Complications: in group A, there were 2 cases of delayed union, 4 cases of needle tract infection, 1 case of trochlear necrosis, and 39 cases of lateral osteophyte; in group B, there was 1 case of malunion, 5 cases of needle tract infection, 1 case of redisplacement, and 26 cases of lateral osteophyte; in group C, there were 2 cases of needle tract infection and 10 cases of lateral osteophyte. There was no significant difference in the incidence of complications among the three groups (P>0.05). No cubitus varus or cubitus valgus deformity was found in all patients. At last follow-up, except that the condylar angle in group A was significantly greater than that in groups B and C (P<0.05), there was no significant difference in other imaging indicators, elbow range of motion, or Mayo score between groups (P>0.05). ConclusionThe Song type 4 of humeral lateralcondylar fracture treated with ultrasound-guided closed reduction and Kirschner wire fixation has a longer operation time, more postoperative complications, and is more prone to lateral osteophyte.
