Gallbladder Agenesis: Report of a Preoperative Diagnosis With Magnetic Resonance Cholangiopancreatography

2020

Agenesis of the gallbladder is an extremely rare congenital entity with shaded clinical and radiologic features, which make the preoperative diagnosis really challenging. Here, we report a case of a 52-year-old symptomatic female with biliary symptoms and contracted gallbladder at ultrasound (US). The final diagnosis was made with magnetic resonance cholangiopancreatography (MRCP) and the treatment was conservative. However, diagnosing this condition preoperatively is still challenging. However, with innovations in terms of biliary tract imaging technique, and with better knowledge of this entity, many unnecessary surgical procedures might be avoided.

Infarct characterization using CT

2017

Myocardial infarction (MI) is a major cause of death and disability worldwide. The incidence is not expected to diminish, despite better prevention, diagnosis and treatment, because of the ageing population in industrialized countries and unhealthy lifestyles in developing countries. Nowadays it is highly requested an imaging tool able to evaluate MI and viability. Technology improvements determined an expansion of clinical indications from coronary plaque evaluation to functional applications (perfusion, ischemia and viability after MI) integrating additional phases and information in the mainstream examination. Cardiac computed tomography (CCT) and cardiac MR (CMR) employ different contra…

A topodiagnostic investigation on body lateropulsion in medullary infarcts.

2005

Body lateropulsion may occur without signs of vestibular dysfunction and vestibular nucleus involvement. The authors examined 10 such patients with three-dimensional brainstem mapping. Body lateropulsion without limb ataxia reflected an impairment of vestibulospinal postural control caused by a lesion of the descending lateral vestibulospinal tract, whereas body lateropulsion with limb ataxia was probably the consequence of impaired or absent proprioceptive information caused by a lesion of the ascending dorsal spino-cerebellar tract.

Repair of a spinal pseudomeningocele in a delayed postsurgical cerebrospinal fluid leak using titanium U-clips: Technical note

2020

Abstract Introduction Chronic cerebrospinal fluid leak (CCFL) represents a possible event following spine surgery, with an incidence rate ranging from 5 to 18%. In literature have been reported few modification techniques that involved the use of titanium U-clips with the aim to reduce dural traumatism during its closure but only after non-accidental durotomy. Case illustration We report the case of a 47-year-old female with history of L5-S1 microsurgical discectomy. After one year the patient was admitted to our unit because she presented progressive skin swelling in the lumbar region, intermittent headache and recurrent episodes of lipothymia. One-year MRI showed a voluminous subcutaneous…

Repeated Echocardiographic Left Ventricular Ejection Fraction Measurements: A Strong and Accessible Tool for Detecting At High Risk of Heart Failure …

2011

Abstract Abstract 3197 Background: The prognosis for thalassemia major (TM) has dramatically improved in the last two decades. However, many transfusion-dependent patients continue to develop secondary iron overloading, and eventually death, particularly from cardiac disease. The possibility of detecting easily and earliest the patients at risk of cardiac death is so far the main challenge of clinical management of these patients. Therefore, the mean reduction of Left Ventricular Ejection Fraction (LVEF), determined by echocardiography, was evaluated over the time. Methods: Among the 413 observed patients only 188 had complete records for LVEF measurements during, at least, five considered …

Resultados de la estrategia farmacoinvasiva y de la angioplastia primaria en la reperfusión del infarto con elevación del segmento ST. Estudio con re…

2011

Introduction and objectives: Pharmacoinvasive strategy represents an attractive alternative to primary angioplasty. Using cardiovascular magnetic resonance imaging we compared the left ventricular outcome of the pharmacoinvasive strategy and primary angioplasty for the reperfusion of ST-segment elevation myocardial infarction. Methods: Cardiovascular magnetic resonance was performed 1 week and 6 months after infarction in two consecutive cohorts of patients included in a prospective university hospital ST-segment elevation myocardial infarction registry. During the period 2004-2006, 151 patients were treated with pharmacoinvasive strategy (thrombolysis followed by routine non-immediate angi…

Right/Left Ventricular Blood Pool T2 Ratio as an Innovative Cardiac MRI Screening Tool for the Identification of Left‐to‐Right Shunts in Patients Wit…

2021

Background Left-to-right (L-R) shunts are characterized by a pathological connection between high- and low-pressure systems, leading to a mixing of oxygen-rich blood with low oxygenated blood. They are typically diagnosed by phase-contrast cardiac magnetic resonance imaging (MRI) which requires extensive planning. T2 is sensitive to blood oxygenation and may be able to detect oxygenation differences between the left (LV) and right ventricles (RV) caused by L-R shunts. Purpose To test the feasibility of routine T2 mapping to detect L-R shunts. Study type Retrospective. Population Patients with known L-R shunts (N = 27), patients with RV disease without L-R shunts (N = 21), and healthy volunt…

Imaging Approach for Evaluation of Focal Liver Lesions

2009

Focal liver lesions are common in the general population. Radiology (imaging) plays a pivotal role for the diagnosis, staging, treatment planning, and follow-up of focal liver lesions. To maximize lesion detection and characterization, imaging needs to be performed with appropriate equipment by using protocols carefully designed on the basis of the underlying clinical context. In addition, the decision of an imaging modality cannot be based on the diagnostic accuracy of an imaging test solely but must also consider patient safety and cost-effectiveness.

Abstract Background Standard therapy for localised, resectable high risk soft tissue sarcomas consists of wide excision and radiotherapy over several weeks. This treatment schedule is hardly feasible in geriatric and frail patients. In order not to withhold radiotherapy from these patients, hypofractionated radiotherapy with 25 Gy in 5 fractions was evaluated in a geriatric patient population. Patients and methods A retrospective analysis was performed of 18 geriatric patients with resectable high risk soft tissue sarcomas of extremities and thoracic wall. Wound healing and short term oncologic outcome were analysed. In addition, dose constraints for radiotherapy of the extremities were tra…

Cost-effectiveness analysis of statins in primary care: results from the Arteris cohort study.

2021

BACKGROUND The Swiss Federal Office of Public Health performed a health technology assessment regarding statins in primary care. The chosen models may lead to a situation where a clinically indicated statin therapy is estimated not to be cost effective. METHODS We performed a cohort study regarding cardiovascular events, comparing SCORE and AGLA risk categories with tertiles of carotid plaque burden and used two models for cost-effectiveness analysis of high-potency statins. RESULTS Subjects (n = 2842) were followed up for 5.9 ± 2.9 years with the occurrence of 154 cardiovascular events (extrapolated 10-year risk was 9.2%). Carotid plaque imaging (total plaque area, TPA) significantly impro…
