Corona mortis, Latin for "crown of death", is a common variant vascular anastomosis between the external iliac artery or deep inferior epigastric artery and the obturator artery. It is reported to be present in a third of patients on routine multi-detector CT examination 1,4. Knowledge of this variant vascular anastomosis is critical for surgical planning and in pelvic trauma, as it is susceptible to vascular injury given its posterior relation to the superior pubic rami 2. Anatomy: Abdominopelvic.

Accessory fissures of the lung usually occur at the borders of bronchopulmonary segments. They are common normal variants but are less commonly seen on imaging. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Updating… Please wait.
Interventional radiology IR is a medical subspecialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy , computed tomography , magnetic resonance imaging , or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices. Diagnostic IR procedures are those intended to help make a diagnosis or guide further medical treatment, and include image-guided biopsy of a tumor or injection of an imaging contrast agent into a hollow structure, such as a blood vessel or a duct. By contrast, therapeutic IR procedures provide direct treatment—they include catheter-based medicine delivery, medical device placement e. The main benefits of interventional radiology techniques are that they can reach the deep structures of the body through a body orifice or tiny incision using small needles and wires.
We found elevated levels of circulating endothelial cells CECs , a biomarker of vascular injury, in COVID convalescents compared to healthy controls. In particular, those with pre-existing conditions e. Several proinflammatory and activated T lymphocyte-associated cytokines sustained from acute infection to recovery phase, which correlated positively with CEC measures, implicating cytokine-driven endothelial dysfunction. As of February 21, , there have been more than million confirmed cases and 2.
