Abdominal doppler ultrasound

Nonmalignant portal vein thrombosis (PVT) is a common complication of cirrhosis especially at the stage of decompensations. The diagnosis of PVT in cirrhosis is often incidental and it may be detected during routine semestral abdominal ultrasound with Doppler during screening for hepatocellular carcinoma or during hospitalization for decompensated cirrhosis. After detection of PVT on abdominal ultrasound, it is important to evaluate patients with cross-sectional imaging to determine the age of thrombus, whether acute or chronic, the extent and degree of luminal occlusion of the portal vein, and to rule out hepatocellular carcinoma or other underlying malignancy...

BACKGROUND: Metabolic-associated fatty liver disease (MAFLD) and cardiovascular diseases have mutual risk factors that contribute to pathogenic processes, increasing mortality and morbidity. This study aimed to evaluate variations in left ventricular (LV) structure and diastolic function among different subtypes and severity degrees of MAFLD patients, allowing early identification, intervention, and prevention of severe cardiac outcomes in high-risk populations. RESULTS: The cross-sectional study included 142 MAFLD patients and 142 non-MAFLD participants as a control group...

Methods: The clinicopathological data and follow-up data of 12 patients with OYST admitted to the Affiliated Hospital of Qingdao University from January 2013 to December 2020 were retrospectively analyzed, and the diagnosis, treatment and prognosis of OYST patients were summarized. Results: (1) The age of 12 patients with OYST ranged from 11 to 37 years, with a median age of 20 years. At the first visit, all 12 patients had pelvic masses...

An inflammatory myofibroblastic tumor (IMT), frequently misdiagnosed as a malignant neoplasm, is a rare tumor characterized by the presence of myofibroblastic spindle cells and infiltration of inflammatory cells. In the current study, a 49-year-old female patient with a huge abdominal mass in the left abdominal wall was examined. Diagnostic procedures included blood tests, as well as ultrasound, Doppler, and computed tomography (CT) scans, which revealed the presence of a huge complex multiloculated cystic lesion measuring 30 x 37 x 20 cm...

BACKGROUND: Assessing the umbilical artery pulsatility index (UA PI) via Doppler measurements plays a critical role in evaluating fetal growth impairment. This study aims to investigate perinatal outcomes associated with discordant PIs of umbilical arteries (UAs) in growth-restricted fetuses. METHODS: In this retrospective cohort study, all singleton pregnancies were included if their estimated fetal weight (EFW) and/or abdominal circumference (AC) fell below the 10th percentile for gestational age (2017-2022)...

OBJECTIVE: The efficiency of ovarian tissue transplantation (OTT) was established in terms of ovarian function recovery (95% of cases), number of live births (over 200 worldwide to date) and induction of puberty. Unfortunately, the lack of international registries and the fact that many centers have not yet reported their outcomes, lead to poor knowledge of the exact fertility data. The aim of the study is to describe our experience with OTT to restore ovarian function and fertility. METHODS: This study was designed as a single-center, observational, retrospective, cohort study that includes women who underwent OTT between December 2012 and June 2023 at our center...

Aortic coarctation is characterized by a segmental narrowing of the aortic lumen, usually diagnosed and treated in the neonatal period or early childhood, but can remain undiagnosed until adulthood. It manifests as a broad spectrum of signs and symptoms, ranging from mild to severe, of which arterial hypertension is one of the most common. In this article, the authors describe the clinical case of a 9-year-old child under investigation in the Pediatric Department for secondary causes of arterial hypertension...

OBJECTIVE: To assess the association of the umbilicocerebral ratio (UCR) with adverse perinatal outcome in late preterm small-for-gestational age (SGA) fetuses and to investigate the effect on perinatal outcomes of immediate delivery. DESIGN: Multicentre cohort study with nested randomised controlled trial (RCT). SETTING: Nineteen secondary and tertiary care centres. POPULATION: Singleton SGA pregnancies (estimated fetal weight [EFW] or fetal abdominal circumference [FAC] <10th centile) from 32 to 36+6  weeks...

Adult intussusception is a rare condition characterized by the telescoping of one segment of the intestine into an adjacent segment. Prompt recognition and intervention are crucial due to the potential for serious complications. The present case is of adult ileocolic intussusception in a 47-year-old male patient who underwent appendectomy three weeks prior. The patient presented with constipation, lower abdominal pain, and vomiting. A transabdominal ultrasound revealed characteristic sonographic features, including a target appearance at the transverse view and the pseudokidney sign of the longitudinal view associated with the presence of reactive lymph nodes...

RATIONALE: Cellular uterine leiomyomas (CL) represent the prevailing subtype among uterine leiomyomas. In this study, we report a case of recurrent peritoneal disseminated uterine fibroids 2 years after single-port laparoscopic gasless myomectomy. This article endeavors to examine the potential limitations of the aforementioned surgical procedure and outline the distinguishing features of recurrent cases with primary postoperative pathology as CL. Additionally, it aims to provide a summary of previous retrospective studies on CL and propose the existence of immunohistochemical molecules that may serve as predictors for the postoperative recurrence of cellular uterine fibroids...

OBJECTIVES: Although respiratory failure is the most common feature in coronavirus disease 2019 (COVID-19), abdominal organ involvement is likewise frequently observed. To investigate visceral and thoracic circulation and abdominal organ damage in COVID-19 patients. MATERIALS AND METHODS: A monocentric observational study was carried on. In COVID-19 patients affected by acute respiratory distress syndrome (ARDS) (n = 31) or mild pneumonia (n = 60) thoracoabdominal circulation was evaluated using Doppler-ultrasound and computed tomography...

A spectrum of critical abdominal pathological conditions that might occur in neonates and children warrants real-time point-of-care abdominal ultrasound (abdominal POCUS) assessment. Abdominal radiographs have limited value with low sensitivity and specificity in many cases and have no value in assessing abdominal organ perfusion and microcirculation (Rehan et al. in Clin Pediatr (Phila) 38(11):637-643, 1999). The advantages of abdominal POCUS include that it is non-invasive, easily available, can provide information in real-time, and can guide therapeutic intervention (such as paracentesis and urinary bladder catheterization), making it a crucial tool for use in pediatric and neonatal abdominal emergencies (Martínez Biarge et al...

OBJECTIVES: Well-established clinical practice to assess progress in labor involves routine abdominal palpation and vaginal examination (VE). However, VE is subjective, poorly reproducible and painful for women. In this study, our aim is to evaluate the feasibility of systematically integrating transabdominal and transperineal ultrasound assessment of fetal position, psAOP, HPD and SCD to monitor labor progress in women undergoing induction of labor (IOL). We also aim at determining if ultrasound can reduce women's pain during examinations...

INTRODUCTION AND IMPORTANCE: Intraparenchymal renal artery aneurysms are a really rare condition that represents <10 % of all renal artery aneurysms. They are more often caused by trauma or iatrogenic injury and their rupture can lead to life-threatening hemorrhage. CASE PRESENTATION: We report the case of a 25-year-old male with history of back stab wound three months before being admitted to our unity. The patient presented a macroscopic hematuria three days after the injury...

OBJECTIVES: To assess the predictive accuracy of three-dimensional (3D) power Doppler combined with two-dimensional (2D) Doppler ultrasonography in detecting fetal growth restriction (FGR). METHODS: The study was conducted on singleton pregnancies presenting for growth ultrasound examinations between 20 and 40 weeks of gestation. 63 patients with FGR were enrolled and matched 1:1.8 for gestational age with normal fetuses. Both groups were further divided into subgroups, with 32 weeks as the threshold-early-onset and late-onset FGR groups, and corresponding control groups...

BACKGROUND: Some hydatid cysts of cystic echinococcosis type 1 (CE1) lack well-defined cyst walls or distinctive endocysts, making them difficult to differentiate from simple hepatic cysts. AIM: To investigate the diagnostic methods for atypical hepatic CE1 and the clinical efficacy of laparoscopic surgeries. METHODS: The clinical data of 93 patients who had a history of visiting endemic areas of CE and were diagnosed with cystic liver lesions for the first time at the People's Hospital of Xinjiang Uygur Autonomous Region (China) from January 2018 to September 2023 were retrospectively analyzed...

Albeit rare, renal vein abnormalities on autopsy and in cases of abdominal surgery complications have been reported and should be kept in mind when performing invasive procedures, such as renal biopsy. We detected a rare renal vein abnormality on colour Doppler ultrasound before renal biopsy, thereby, avoiding a haemorrhagic complication. A 10-year-old boy presented to our department for the first time because of incidental findings of haematuria and proteinuria. We suspected chronic glomerulonephritis and scheduled an ultrasound-guided percutaneous renal biopsy...

RATIONALE: Intercostal hemangioma (IH) is an extremely rare disease, with only 18 cases reported in the past 30 years. Herein, we report the first case of IH coexisting with multiple hepatic hemangiomas, which recurred 32 months after surgery with rib erosion. IHs are invasive and difficult to distinguish from other intercostal tumors on imaging. To date, there have been no review articles on the imaging findings of IHs. We hope that this article will help clinicians improve their ability to diagnose and treat IH...

BACKGROUND AND AIMS: Abnormal liver chemistries are common in Turner syndrome (TS). Guidelines suggest that TS patients undergo annual screening of liver enzymes, but the role of non-invasive screening for steatosis and fibrosis is not clearly defined. We compared the prevalence of hepatic steatosis and fibrosis among TS patients to healthy controls using ultrasound with shear-wave elastography (SWE) and assessed for risk factors associated with steatosis and fibrosis in TS. METHODS: Prospective case-control study of TS versus control patients from 2019 to 2021...

Vector flow imaging (VFI) is an innovative ultrasound flow measurement technology. Compared with the traditional color Doppler and spectral Doppler, VFI has the advantages of independence of angle correction and direct acquisition of real-time amplitude and direction of flow. Transverse oscillation (TO) method is one of the effective methods for vector flow imaging. However, a complete and detailed algorithm validation process based on commercial ultrasound machines is still lacking due to more complex convex probes...
