The ileocecal valve, located in the central part of the ileocecal bowel segment, is rarely the primary site of disease processes. It is usually involved by pathologies in adjacent bowel segments. These are primarily infectious diseases such as yersiniosis, campylobacteriosis and salmonellosis. Typical location of Crohn's lesions also promotes valve involvement. The appearance of the lesions in these cases is characterized by a symmetrical submucosal thickening of the bowel involved over a longer segment. Non-malignant valvular hyperplasia is relatively commonly identified as lipomatosis, manifested by symmetrical enlargement and smooth outlines. However, valvular lipoma causing an asymmetrical hyperechoic bulge is a rare finding. ileocecal valve lipomatosis or lipoma should not be misdiagnosed as a lipoma of the cecoascending part of the colon and, the other way round, a right colonic lipoma should not be mistaken for a fatty valve. Polyps on the ileocecal valve, although sometimes detected, were not identified in our material. Adenocarcinoma, which is found in the cecum in approximately ¼ of cases, is the most common malignancy, followed by neuroendocrine tumor and, rarely, lymphoma. In three cases of malignant involvement of the ileocecal valve, we observed irregular hypoechoic thickening with complete loss of wall stratification, with the lesions causing symptoms of small bowel obstruction in two of these cases. The nearly forgotten ileocecal valve syndrome, also known as Bauhin's ileocecal valve syndrome, characterized by intermittent right iliac fossa pain, is also briefly discussed. Transabdominal ultrasound can be used as an initial diagnostic tool in some of these pathologies.","PeriodicalId":45612,"journal":{"name":"Journal of Ultrasonography","volume":"24 98","pages":"1-11"},"PeriodicalIF":1.3,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11653064/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142856183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to compare the novel ultralow umbilical artery catheter position (catheter tip at the junction of the umbilical and internal iliac arteries) versus the conventional high umbilical artery catheter position (tip in the aorta, above the diaphragm) for the incidence of thrombosis.Study design: This study was conducted in a nonacademic, tertiary-referral neonatal center. The insertion and placement of the umbilical artery catheter was performed under continuous ultrasound guidance. Serial ultrasound examinations were performed to identify thrombosis in 38 consecutive newborns with an umbilical artery catheter placed in the novel ultralow position. The control group consisted of 50 infants with an umbilical artery catheter placed in the standard position.Results: The incidence of thrombosis requiring anticoagulant treatment was 22% in neonates with an umbilical artery catheter in the standard position. No thrombosis was detected in those with an umbilical artery catheter placed in the ultralow position. The study and control groups had similar catheter indwelling times (mean, 8.2 ± 4.1 vs. 8.5 ± 4.0 days, p = 0.687).Conclusions: This is the first report to present a novel position for the placement of umbilical artery catheters.

The variant was symptomatic in three cases in which possible distal compression was clinically suspected. A branch of the ulnar nerve made a loop around the flexor carpi ulnaris, which also presented with a variation of normal anatomy. In symptomatic patients, the diameter of the aberrant branch (retrospectively measured) was significantly enlarged.Conclusions: High-resolution ultrasound can accurately demonstrate ulnar nerve variants even when only small nerve fascicles are involved, which may be clinically relevant and misinterpreted. Loops of the ulnar nerve are rare, but likely under-recognized. We think that symptoms are generally tolerated by patients if the motor branch of the ulnar nerve is not affected, as in our cases.","PeriodicalId":45612,"journal":{"name":"Journal of Ultrasonography","volume":"24 98","pages":"1-5"},"PeriodicalIF":1.3,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11608064/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142773540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to VCUG, both RBUS and ceVUS provide more intuitive diagnoses for duplex kidneys with VUR and ureterocele. Additionally, there is good consistency between ceVUS and VCUG in grading VUR.

Success in the maturation process was defined by ultrasonographic criteria at six weeks.Results: Thirty-seven patients were included. With a mean ± standard deviation age of 40 ± 14 years, 73% were male, 65% had type-2 diabetes mellitus, and 95% had hypertension. Arteriovenous fistulas were brachycephalic in 18 patients (49%), brachymedian in nine patients (24%), brachycommunicating posterior in five patients (14%), brachibasal in three patients (8%), radiocephalic in two patients (8%), and radiocephalic in two patients (5%). Fourteen percent of patients had unsuccessful maturation. The vein diameter was 4.3 ± 1.0 mm (maturation group) vs 3.2 ± 0.9 mm (non-maturation group), p = 0.04. The artery diameter was similar: 4.5 ± 0.6 vs 4.5 ± 0.4, p = 0.88.

Color Doppler imaging and power Doppler imaging are considered the first and second generations of flow ultrasound assessment tools, respectively. Subsequently, the introduction of contrastenhanced ultrasound has significantly improved the assessment of arterial and venous vascular patterns in lesions and vessels. 'Blood flow brightness-mode imaging' or 'B-flow', a non-Doppler ultrasound flow assessment mode introduced more recently, provides even more information for ultrasound users in flow assessment. Microvascular imaging, introduced about a decade ago, is the third generation of Doppler non-contrast ultrasound flow modes, and is growing in popularity. Using a special wall filter, microvascular imaging overcomes the limitations of color Doppler imaging and power Doppler imaging in the detection of slow flowing signals. Advanced dynamic flow is a third-generation non-contrast Doppler flow technology that has so far gained popularity in obstetric ultrasound, commonly used to evaluate fetal umbilical vessels and heart chambers.

We interviewed consenting patients on maintenance dialysis performed for at least one month via an upper limb arteriovenous fistula, which was subsequently scanned. We compared the proportions and means using chi-squared and ANOVA tests, respectively, with a threshold for significance set at a p value ≥0.05.Results: Between 1 July and 31 August 2022, we recruited a total of 41 participants, of whom 56.1% were males.

Plain X-ray is the gold standard test for diagnosing fractures of long bones but it exposes patients to radiation with its associated health hazards. The use of ultrasonography has been proposed as a safer diagnostic test. This review aimed to summarize the evidence regarding the diagnostic accuracy of bedside ultrasonography for identifying distal forearm fractures in pediatric patients.Methods: Electronic search of MEDLINE, EMBASE, Cochrane Library, Google Scholar, and Best Bets databases was conducted for studies published from inception to May 2017. The search terms used included \"forearm\" and \"fractures\" and \"children.\"Results: Seven studies were included in the review. The overall accuracy of ultrasonography ranged from 78.6% to 99.5%. The sensitivity and specificity ranged from 85% to 100%, and from 73% to 100%, respectively. The area under the curve for ultrasonography ranged from 0.79 to 1.00.Conclusion: Ultrasound is a reliable diagnostic tool for the diagnosis of distal forearm fractures in children when performed by well-trained emergency doctors and through using an appropriate viewing method.
