BACKGROUND Ovarian torsion can be seen in the otherwise-normal ovary and is a challenging issue in the emergency department. The aims were (1) to evaluate and compare the surgically verified ovarian torsion cases in otherwise-normal ovaries and ovaries including a mass or cyst and (2) to investigate whether the normal-appearing ovaries on ultrasound examination affected the diagnosis of ovarian torsion or not. MATERIAL AND METHODS A retrospective cohort study design was used. The medical records of all postmenarchal adolescent girls with surgically verified ovarian torsion treated in a university hospital from 2010 to 2016 were reviewed...

Autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap has become increasingly popular because of its unique advantages. However, compared with some other forms of abdominal-based autologous reconstruction, DIEP flaps are associated with an increased risk of venous congestion. Many techniques-or lifeboats-have been introduced to diagnose and treat this potentially devastating complication. In this case report, we describe a novel strategy to augment venous drainage when venous congestion is encountered...

Arterial stiffness can be evaluated by calculating pulse wave velocity (PWV), i.e., the speed with which the pulse wave travels in a conduit vessel. This parameter is being increasingly investigated in small rodent models in which it is used for assessing alterations in vascular function related to particular genotypes/treatments or for characterizing cardiovascular disease progression. This protocol describes an image processing algorithm which leads to non-invasive arterial PWV measurement in mice using ultrasound (US) images only...

We report a rare case of allograft loss from acute Page kidney secondary to trauma that occurred 12 years after kidney transplantation. A 67-year-old Caucasian male with a past surgical history of kidney transplant presented to the emergency department at a local hospital with left lower abdominal tenderness. He recalled that his cat, which weighs 15 lbs, jumped on his abdomen 7 d prior. On physical examination, a small tender mass was noticed at the incisional site of the kidney transplant. He was producing a normal amount of urine without hematuria...

Natalia Gonzalez, Togas Tulandi
A relatively new type of ectopic pregnancy is cesarean scar pregnancy (CSP). This is related to the increasing number of cesarean deliveries and to the advances in imaging. There are 2 types of CSP; CSP with progression to cervicoisthmic space or uterine cavity (type I, endogenic type) or with deep invasion of scar defect with progression towards bladder and abdominal cavity (type II, exogenic type). The endogenic type of CSP could result in a viable pregnancy; yet with a high risk of bleeding at the placental site...

Metastatic melanoma is an aggressive disease that can spread to many organs of the body. In rare cases, it can spread to the gallbladder causing secondary lesions, yet presenting with little to no symptoms. Therefore, most cases of metastatic melanoma lesions to the gallbladder go undiagnosed. Here, we present the case of a 41-year-old male with a four-month history of melanoma of the face, with a postresection status, who presented with right upper quadrant abdominal pain. Doppler ultrasound and computed tomography confirmed the presence of a mass on the gallbladder...

BACKGROUND: Exercise in the preoperative period, or prehabilitation, continues to evolve as an important tool in optimising patients awaiting major intra-abdominal surgery. It has been shown to reduce rates of post-operative morbidity and length of hospital stay. The mechanism by which this is achieved remains poorly understood. Adaptations in mesenteric flow in response to exercise may play a role in improving post-operative recovery by reducing rates of ileus and anastomotic leak. AIMS: To systematically review the existing literature to clarify the impact of exercise on mesenteric arterial blood flow using Doppler ultrasound...

Takayasu's arteritis is known to cover the youngest age group in the etiology of secondary hypertension. The type 3 pattern is rare and involves the thoraco-abdominal aorta and its main abdominal branches. Here, we present the imaging results of a patient who had been followed up for systemic arterial hypertension and was diagnosed with Takayasu's arteritis type 3 by CT and MR angiography following bilateral detection of a parvus-tardus Doppler signal modulation in the renal arteries. We discuss the differential diagnoses that should be considered when observing a tardus-parvus Doppler signal...

Ichiro Yasuda, Hsiu-Po Wang
Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) is widely used for reducing pain originating from upper abdominal organs. It is mainly indicated to treat pancreatic cancer pain, but also to relieve pain as a result of chronic pancreatitis. Real-time guidance and color Doppler imaging by EUS made the procedure easier and safer, resulting in greater pain relief. Currently, two techniques are used for EUS-CPN. The classic approach, known as the central technique, involves injection of a neurolytic agent at the base of the celiac axis...

BACKGROUND: Ultrasound exam as a screening test for abdominal aorta (AA) can visualize the aorta in 99% of patients and has a sensitivity and specificity approaching 100% in screening settings for aortic aneurysm. Pocket Size Imaging Device (PSID) has a potential value as a screening tool, because of its possible use in several clinical settings. Our aim was to assess the impact of demographics and cardiovascular (CV) risk factors on AA size by using PSID in an outpatient screening. METHODS: Consecutive patients, referring for a CV assessment in a 6 months period, were screened...

BACKGROUND: Bioengineered living autologous valves with remodeling and growth capacity represent a promising concept for future cardiac and venous valve repair. A meticulous understanding of the mechanisms involved in recellularization and remodeling is essential for the safe and efficient clinical translation of this technology. In this context, the first investigations of bioengineered vascular grafts in immune-incompetent or transgenic rodents represented an important step. However, the in-vivo assessment of bioengineered synthetic scaffold-based (biodegradable) valve replacements in rodent models has not been achieved to date...

The goal of this study was to evaluate the accuracy of a non-invasive C-plane Doppler estimation of pulsatile blood flow in the lower abdominal vessels of a porcine model. Doppler ultrasound measurements from a matrix array transducer system were compared with invasive volume flow measurements made on the same vessels with a surgically implanted ultrasonic transit-time flow probe. For volume flow rates ranging from 60 to 750 mL/min, agreement was very good, with a Pearson correlation coefficient of 0.97 (p < 0...

BACKGROUND AND PURPOSE: Small infants with biliary atresia and hypoplastic portal veins (PV) are at risk for portal vein thrombosis (PVT) after liver transplantation (LT), which can lead to graft loss and mortality. Extra-anatomical PV reconstruction techniques have been established for adult cases of PVT; however, they have not been widely accepted for infants. METHODS: Here, we report the successful use of an extra-anatomical meso-portal venous jump graft to treat early PVT after LT in a 6-month-old infant with biliary atresia and PV hypoplasia...

INTRODUCTION: Wipple disease (WD) is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as "stroke-like syndrome" or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis...
