The authors report the case of an elderly woman assessed for dyspnea and right costal margin pain, whose chest radiography demonstrated opacity simulating pulmonary lesion, computed tomography revealed vascular origin condition. Acute aortic syndrome due to ruptured atheromatous plaque penetrating through elastic lamina in association with hematoma aneurysm is a relevant differential diagnosis be considered these cases. Relatamos o caso de uma paciente idosa avaliada por apresentar dispneia...

In emerging countries, one of the leading causes death is hemorrhage, and lack cheap, easily available embolization materials problematic. this work we evaluate in-vitro potential EmboBio, a new fully compatible biodegradable agar-agar plant-based polymer with swelling properties, proposed in Torpedo Slurry form. A branched arterial phantom created 4 mm branch bifurcating into two 2.5 mm, four 1.5 ones. It inserted bench test which 40% glycerol/60% saline 0.9% solution circulated via...

To evaluate variables affecting the need for analgesia after ultrasound-guided percutaneous liver biopsy performed on an outpatient basis.This was a retrospective analysis of 1,042 biopsies between 2012 and 2018. The data collected included age sex patient, as well self-reported pain in recovery room, treatment used, indication biopsy, lobe punctured. As per protocol our institution, physicians would re-evaluate patients with mild (1-3 visual analog scale), prescribe analgesics those...
