BACKGROUND: Despite previous reports of robotic-assisted laparoscopic release for median arcuate ligament syndrome (MALS), the safety and efficacy profile of this approach has been difficult to establish due to the rarity of this diagnostic entity. We aim to present our experience from a tertiary minimally invasive surgery referral center. METHODS: A case series was performed whereby all patients who underwent robotic-assisted MAL release from July 2010 to July 2017 at our institution were included...

AIMS: Non-invasive fractional flow reserve derived from coronary CT angiography (FFRCT ) has been shown to be predictive of lesion-specific ischemia as assessed by invasive fractional flow reserve (FFR). However, in practice, clinicians are often faced with an abnormal distal FFRCT in the absence of a discrete obstructive lesion. Using quantitative plaque analysis, we sought to determine the relationship between an abnormal whole vessel FFRCT (V-FFRCT ) and quantitative measures of whole vessel atherosclerosis in coronary arteries without obstructive stenosis...

OBJECTIVE: Patient-based decision aids and other multimedia tools have been developed to help enrich the preoperative discussion between surgeon and patient. Use of these tools, however, can be time-consuming and logistically challenging. We investigated whether simply showing patients their images from preoperative computed tomography (CT) or angiography would improve patients' satisfaction with the preoperative discussion. We also examined whether this improved the patient's understanding and trust and whether it contributed to increased preoperative anxiety...

OBJECTIVES: Giant cell arteritis (GCA) is the most common form of systemic vasculitis. Glucocorticoids are an effective treatment but have significant adverse events and relapses are common. Interleukins 12 (IL-12) and 23 (IL-23) stimulate TH 1 and TH 17 responses and are implicated in the pathogenesis of GCA. The aim of this study was to evaluate the efficacy and safety of IL-12/23 blockade with ustekinumab in GCA. METHODS: We performed a prospective open label study of ustekinumab in patients with refractory GCA...

Traumatic common carotid artery dissection (CCAD) is rare. To our knowledge, only 14 case reports have described traumatic CCAD previously. Here, we report a case of CCAD in a patient with severe trauma. A 50-year-old man was lying on the road after drinking alcohol when a car drove over him. Computed tomography (CT) revealed multiple rib fractures with hemopneumothorax, lung contusion, flail chest, large amount of hematoma with bladder rupture, and fractures on the C6 spinous process, sacral ala, iliac bone, and pubic ramus...

BACKGROUND: Current guidelines for the treatment of acute ischemic stroke are mainly based on the time between symptom onset and initiation of treatment. This time is unknown in patients with wake-up stroke (WUS). We investigated clinical and multimodality CT imaging characteristics on admission in patients with WUS and in patients with a stroke with a known onset time. METHODS: All patients were selected from a large prospective cohort study (Dutch acute stroke study)...

Case summary: A 6-month-old female cat with a history of chronic regurgitation presented with weight loss. CT angiography (CTA) showed severe constriction of the oesophagus due to an aberrant right subclavian artery and Kommerell's diverticulum. The cat was surgically treated and remained clinically normal. More than 1 year after surgery, the general condition of the cat was stable and body weight had increased. Relevance and novel information: This case report describes the clinical findings and surgical management of a cat diagnosed with severe oesophageal constriction caused by an aberrant right subclavian artery with Kommerell's diverticulum (markedly dilated origin of the aberrant right subclavian artery), which are rare vascular anomalies in veterinary medicine and specifically in cats...

Cardiovascular abnormalities are frequently encountered in patients with Turner's syndrome. A 12-year-old girl with Turner's syndrome (TS) was referred from the endocrinology department for management of hypertension. After Echocardiography and CT angiography, we confirmed that she had severe coarctation of the aorta, just distal to the left subclavian artery. Due to high-pressure gradient in the coarct segment, in presence of hypertension, we made the decision for percutaneous intervention of coarctation of aorta...

Radiation-induced coronary heart disease (RICHD) is the second most common cause of morbidity and mortality in patients treated with radiotherapy for breast cancer, Hodgkin's lymphoma and other prevalent mediastinal malignancies. The risk of RICHD increases with radiation dose. Exposed patients may present decades after treatment with manifestations ranging from asymptomatic myocardial perfusion defects to ostial, triple-vessel disease and sudden cardiac death. RICHD is insidious, with a long latency and a tendency to remain silent late into the disease course...
