PURPOSE: To investigate whether acute and transient pressure overload in patients with pregnancy-induced hypertension affects cardiac function in fetuses. METHODS: We enrolled 104 singleton pregnant women with gestational ages ranging 30 to 33 weeks, visiting for prenatal care. Among them, 34 had gestational hypertension (GH), 32 had preeclampsia (PE), and 38 were healthy and formed the control group. Conventional echocardiographic and velocity vector imaging (VVI) variables were prospectively collected...

OBJECTIVES: Blood hemoglobin concentration measurements using a spectrophotometric method (SpHb), and inferior vena cava ultrasonography (IVC-US) are noninvasive methods used to follow-up hemorrhages. We compared their efficacy using voluntary blood donation as a model of moderate (approx. 500 mL) blood loss. METHODS: In this prospective observational study enrolling blood-donor volunteers (BD) and matched controls, we recorded SpHb, IVC diameters, and vital signs...

PURPOSE: This study was undertaken to evaluate the performance of indirect sonographic signs in detecting partial agenesis of the corpus callosum (pACC) at midgestation, focusing on the cavum septum pellucidum (CSP) ratio. METHODS: A retrospective case-controlled study of singleton pregnancies was conducted, examining fetuses diagnosed with isolated pACC and normal controls. At midgestational age, fetal head volumes were imaged with 3D US and stored for the evaluation of indirect sonographic findings in axial planes...

PURPOSE: The objective of this study was to compare the false negative rate, sensitivity and false positive rate of ultrasound (US)-guided fine needle aspiration (FNA) with those of US-guided core needle biopsy (CNB) for large thyroid nodules ≥2.0 cm, which reportedly have an increased risk of thyroid malignancy. METHODS: We retrospectively studied surgically confirmed thyroid nodules that had preoperative US-guided FNA or CNB between March 2005 and December 2013...

Internal carotid arterial dissection is a rare and probably underestimated cause of neonatal stroke. We report a case of neonatal stroke underscoring the role of Doppler sonography of the intracranial arteries for the diagnosis and follow-up tool.

Aneurysm of the inferior vena cava is a rare anomaly with a very few reported cases worldwide. We report the case of a 26-years-old man with acute severe abdominal pain and hypovolemic shock following an episode of syncope. Ultrasonography showed a fusiform aneurysmal dilation of the infra-hepatic inferior vena cava (IVC), with a large saccular portion at its posterolateral wall and mural thrombosis. Abdominal computed tomography scan revealed extension to the right renal vein and adhesion to the right kidney...

A middle cerebral artery peak systolic velocity value (MCA-PSV) persistently greater than 1.5 times the median of the normal population is utilized to detect moderate and severe anemia in fetuses at risk. Cytomegalovirus (CMV) is the most common perinatal infection and can cause fetal anemia. We present four cases with CMV perinatal infection. Although their MCA-PSV values were the highest recorded in normal as well as in anemic fetuses, only two of them developed moderate or severe anemia. These findings suggest that high MCA-PSV values in cases with perinatal CMV infection may have a different pathophysiologic mechanism than anemia...

PURPOSE: High-dose steroid therapy (HDST) has frequent side-effects that appear at its cessation and depend on its dose. However, there is a lack of studies about the acute effects of HDST on cardiac function in adult patients. METHODS: We included in this study 30 patients who underwent HDST (intravenously at doses ranging from 250 to 1000 mg) and 30 healthy control subjects with similar demographic and clinical characteristics, between September and December 2016...

Kinking of the kidney transplant vessels late after the operation is a rare complication that can lead to significant morbidity and mortality. We present a case of positional ischemia of the renal allograft resulting from dynamic and positional kinking of the graft vasculature, which was diagnosed by ultrasonography with the patient standing. The graft was repositioned into the sub-rectus pocket and the ischaemic injury resolved.

Criss-cross heart (CCH) is an extremely rare complex congenital heart malformation. It accounts for less than 0.1% of congenital heart diseases. Here, we describe a unique case of CCH with double-outlet right ventricle, huge subpulmonary ventricular septal defect, bicuspid pulmonary valve, and right-hand aortic arch. The anatomic features were observed with echocardiography, and the diagnosis was confirmed at surgery. Many variations of CCH have been described. The present case expands the spectrum of this entity and may provide new insight into this complex anatomy...

PURPOSE: To investigate with Doppler ultrasonography the maxillary and middle meningeal arteries in the infratemporal fossa, and describe their hemodynamic characteristics. METHODS: We included 24 female and 11 male volunteers without vascular diseases, with a median age of 43 years. We used the acoustic window, enlarged by subjects half-opening their mouth, located below the zygomatic arch, in front of temporo-mandibular joint, to reach the maxillary and middle meningeal arteries...

Leiomyosarcoma of the inferior vena cava is a rare malignant tumor originating from smooth muscle cells of the vascular media. Its preoperative diagnosis by conventional noninvasive examinations such as abdominal ultrasonography, X-ray computed tomography, and magnetic resonance imaging, may be difficult because of their nonspecific findings. We present the case of a 72-year-old woman with leiomyosarcoma of the inferior vena cava diagnosed by intravascular ultrasonography.

Otocephaly is an extremely rare lethal congenital anomaly characterized by the absence or underdevelopment of the mandible. The clinical presentation is variable. Some cases may present with severe micrognathia as the only anomaly seen prenatally. The key to early diagnosis is careful assessment of the location of the fetal ears on 2D ultrasound examination.

Endoscopic ultrasound-guided sampling is indicated to achieve an accurate diagnosis of subepithelial lesions of the stomach when a standard biopsy fails. Gastric carcinoma with lymphoid stroma (GCLS) is located under the epithelial layer with dense lymphocytic infiltration, making a pathological diagnosis by a biopsy difficult. We herein report a case of the pathological diagnosis of GCLS using an endoscopic ultrasound-guided fine-needle biopsy. The patient underwent distal gastrectomy and was diagnosed with Epstein-Barr virus-negative cancer...

PURPOSE: To evaluate strain elastography as a complementary tool for characterization of lesions identified during second-look MRI-directed sonographic examination. METHODS: We reviewed 83 breast lesions evaluated with MRI, secondlook ultrasound (US) and strain elastography in 75 consecutive patients (median age, 56 years). US-guided biopsies were performed in all cases. RESULTS: After histopathological examination, 44 lesions were benign, 38 were malignant and 1 was high-risk...
