OBJECTIVE: Accuracy of ultrasound in diagnosis of ovarian torsion remains controversial, with some studies reporting correct diagnosis in only 23% to 66% of cases. Normal Doppler flow does not necessarily exclude an ovarian torsion; in fact, it may lead to missing the diagnosis and has been show to delay management. The objective of our study was to assess sensitivity and specificity of ultrasound diagnosis of ovarian torsion and to analyze the factors contributing to correct and incorrect diagnosis...

BACKGROUND: Color Doppler ultrasound (CDUS) has not been routinely used in plastic and reconstructive surgery. Barriers to use have included large, cumbersome equipment, low-definition images, cost, and availability. In addition, programs in plastic surgery have not included training with ultrasound (US); thus, many current-day practitioners are unfamiliar with and reluctant to use this technology. Nevertheless, recent studies have demonstrated the utility of US in surgical planning. With the miniaturization, clearer imaging, and decreased costs of the latest US technology, previous barriers to use have largely been eliminated...

Background: Chronic Hepatitis C virus (HCV) infection and liver cirrhosis may be associated with atherosclerosis and coronary artery disease (CAD). There are two phases to atherosclerosis, Subclinical and Clinical. Assessment of atherosclerosis may be started at its Subclinical phase by the evaluation of Epicardial Fat Thickness (EpFT) and Carotid Intima Thickness (CIMT). Aim of the study: The aim of the study was to evaluate Clinical and Subclinical atherosclerosis in chronic HCV patients with and without liver cirrhosis by evaluating CIMT and EpFT and correlating the results with Child-Pugh functional scoring of cirrhosis as well as with ultrasound and laboratory parameters that define the severity of liver disease...

Endovascular repair of abdominal aortic aneurysms have been performed successfully since 1991. However, 20% to 50% of these patients may develop an endoleak or continued aneurysmal sac expansion or perfusion despite stent graft coverage. Current recommendations suggest lifelong surveillance with computed tomographic angiography (CTA) at least 1 month after intervention and yearly after that. In select patients with a stable aneurysm sac on computed tomography performed 1 year after treatment, future screening could be performed with ultrasonography...

Pseudoaneurysm (PA) of the cystic artery is rare. Most of the reported cases are iatrogenic and develop secondary to liver biopsy, laparoscopic cholecystectomy, ERCP, and liver transplant. Other reported causes include trauma, malignancy, arteriovenous malformations, and inflammation in the hepatobiliary and pancreatic system. Cystic artery psuedoaneurysm is usually asymptomatic but may also present as vague abdominal pain, intra-abdominal mass, and hemobilia. In the event of rupture, it may present as a catastrophic intra-peritoneal bleeding with hemorrhagic shock...

Horseshoe kidney (HSK) is a congenital defect of the urinary tract that occurs in 0.25% of the general population. Laparoscopic Vascular Hitch (LVH) according to Hellstrom-Chapman represent an alternative approach in treatment of extrinsic hydronephrosis by crossing vessels (CV) in pediatric age. In our Department from 2006 to 2016, 36 children with extrinsic-Uretero-Pelvic-Junction (UPJ)-Obstruction (UPJO) underwent laparoscopic vessels transposition. Over the last 4years, we have treated three patients with extrinsic hydronephrosis in HSK; two males and one female respectively of 6, 7 and 8years...

Nutcracker phenomenon is the descriptor for a patient's anatomy whenever the left renal vein becomes compressed between the abdominal aorta and the superior mesenteric artery. Nutcracker syndrome is the terminology used when the nutcracker phenomenon is accompanied by symptoms including pain (abdominal, flank, pelvic), hematuria, and orthostatic proteinuria. Diagnosis can be made with Doppler ultrasound, venography, computed tomography, or magnetic resonance imaging. This case demonstrates some of the typical findings of nutcracker syndrome...

BACKGROUND: Abdominal pain is one of the most common chief complaints of patients presenting to emergency departments, and emergency physicians (EPs) often evaluate patients with right lower quadrant abdominal pain. Ovarian torsion is a rare cause of abdominal pain, but early diagnosis is essential for salvage of the affected ovary. The diagnostic study of choice for ovarian torsion is a pelvic ultrasound with color Doppler, but it is important for EPs and radiologists to be aware of findings of ovarian torsion that might appear on computed tomography (CT)...

Arterial thrombosis of the newborn is rare and associated with poor prognosis, often attributed to umbilical arterial catheterization. The aortic and spontaneous forms are exceptional. Its severity requires fast and effective treatment. Although therapeutic means are numerous, no consensus has been established to date although thrombolysis and heparin therapy appear to give good results depending on the site and extent of thrombosis. We report a case of extensive thrombosis of the abdominal aorta in a 5-day-old newborn, revealed by acute hypernatremic dehydration...

By consensus, late fetal growth restriction is that diagnosed >32 weeks. This condition is mildly associated with a higher risk of perinatal hypoxic events and suboptimal neurodevelopment. Histologically, it is characterized by the presence of uteroplacental vascular lesions (especially infarcts), although the incidence of such lesions is lower than in preterm fetal growth restriction. Screening procedures for fetal growth restriction need to identify small babies and then differentiate between those who are healthy and those who are pathologically small...

Fetal growth restriction implies failure of a fetus to meet its growth potential and is associated with increased perinatal mortality and morbidity. Therefore, antenatal detection of fetal growth restriction is of major importance in an attempt to deliver improved clinical outcomes. The most commonly used approach towards screening for fetal growth restriction is by means of sonographic fetal weight estimation, to detect fetuses small for gestational age, defined by an estimated fetal weight <10th percentile for gestational age...

The goals of the study described here were to evaluate the feasibility and reproducibility of measuring spleen stiffness (SS) using point shear wave elastography in a series of cirrhotic patients and to investigate whether SS, liver stiffness (LS) and other non-invasive parameters are correlated with the presence of esophagogastric varices (EVs). Fifty-four cirrhotic patients with low-grade EVs or without EVs at esophago-gastro-duodenoscopy were enrolled. They underwent abdominal ultrasound and Doppler ultrasound of hepatic vessels simultaneously with p-SWE of the liver and spleen...
