Superior mesenteric artery (SMA) syndrome is one of the rare causes of small bowel obstruction. It develops following a marked decrease in the angle between SMA and the abdominal aorta due to weight loss, anatomical anomalies, or following surgeries. Nutcracker syndrome in the left renal vein may also occur following a decrease in the aortomesenteric angle. Though SMA syndrome and renal nutcracker syndrome share the same pathogenesis, concurrent development has rarely been reported. Herein, we report a 23-year-old healthy male diagnosed with SMA syndrome and renal nutcracker syndrome due to severe weight reduction...

Ewing's sarcoma/primitive neuroectodermal tumor (EWS/PNET) in the kidney is a rare but high-grade malignant tumor that affects predominantly elder children and adolescents. Patients mostly present with nonspecific symptoms such as abdominal pain and gross hematuria. Since EWS/PNET has a rapid clinical progression with early metastasis and death, it is essential to make an accurate and early diagnosis. Once diagnosed, multimodality treatment, including radical surgery combined with adjuvant chemotherapy, and radiotherapy if necessary, is recommended...

Vascular diseases account for a significant proportion of abdominal pathology and represent a common referral source for abdominal ultrasonographic examinations. B-mode, color Doppler, and spectral Doppler analyses are well-established in the evaluation of abdominal blood vessels although they may occasionally be limited by lower sensitivity for slow flow visualization or the deeper location of abdominal vascular structures. The introduction of microbubbles as ultrasonographic contrast agents has rendered contrast-enhanced ultrasound (CEUS), a valuable complementary ultrasonographic technique, which is capable of addressing clinically significant problems and guiding patient management...

Thoracic endovascular aortic repair (TEVAR) is commonly applied in type-B aortic dissection. For patients with dissection affects descending aorta and extends downward to involve abdominal aorta and possibly iliac arteries, false lumen (FL) expansion might occur post-TEVAR. Predictions of dissection development may assist in medical decision on re-intervention or surgery. In this study, two patients are selected with similar morphological features at initial presentation but with different long-term FL development post-TEVAR (stable and enlarged FL)...

BACKGROUND AND AIMS: Carotid extra-media thickness (EMT) encompasses arterial adventitia and perivascular adipose tissue (PAT). Adventitial remodeling and PAT may contribute independently to functional (stiffness) and structural (remodeling) changes in artery wall properties. Visceral adiposity may contribute to PAT, thereby affecting artery stiffness. We investigated the relationships between carotid artery stiffness, EMT, and visceral adiposity in young, healthy individuals. METHODS: 135 healthy males (20 ± 2 yr, body mass index [BMI] 24...

An important paper describing the Standards of the Polish Ultrasound Society regarding the assessment of portal and hepatic vasculature was published in the Journal of Ultrasonography. Due to the multiplicity of morphological and hemodynamic data required, the time needed to obtain these data and the legal responsibility of doctors for the results, there seems to be a need to determine a clear range of the assessed parameters depending on the reference level of a given healthcare facility. Therefore, the aim of the paper was to present the EFSUMB recommendations on the range of the evaluated ultrasonographic parameters in portal hypertension depending on the reference level...

INTRODUCTION: Suction-assisted lipectomy (SAL) has been considered a relative contraindication for autologous breast reconstruction due to reservations about size and integrity of perforator vessels. Such patients are often not considered ideal candidates for breast reconstruction utilizing deep inferior epigastric perforator (DIEP) and superficial inferior epigastric artery (SIEA) flaps. The aim of this article is to describe our experience with these flaps after SAL. METHODS: Retrospectively, patient charts from 2005 to 2015 were analyzed and 9 patients (13 flaps) were identified who received breast reconstruction after prior donor-site SAL...
