Paraplegia secondary to spinal cord ischaemia is a rare but devastating complication of abdominal aortic aneurysm repair. We report a case of paraplegia following elective endovascular repair of an infrarenal aortic aneurysm. A cerebrospinal fluid (CSF) drain was immediately inserted and resulted in full neurological recovery. This case highlights the fact that endovascular techniques are prone to similar complications as open surgery, and the importance of prompt cerebrospinal fluid drainage in cases of spinal cord ischaemia.
Infected popliteal aneurysm is a rare high-risk condition that can present as an emergency with acute rupture and sepsis. Management of acute ischemia in the presence of local and systemic sepsis is challenging. Open surgery is not always possible and carries a high risk of morbidity and death. An endovascular approach has been advocated in infected aneurysms elsewhere in the body, with good short-term and medium-term outcomes encouraging such approach in the popliteal artery. We report a case of successful endovascular treatment of an infected ruptured popliteal aneurysm with favorable outcome after 2-year follow-up and a related review of the literature.
Inflammation has a central role in atherosclerotic plaque formation and rupture. Intense macrophage inflammatory activity results in microcalcifications which are strongly associated with plaque vulnerability. Microcalcifications with specific critical size between 5 and 65 μ, located in the fibrous cap producing local mechanical stress on the plaque surface and may directly contribute to plaque rupture. Hence, accurate assessment of microcalcifications size and dimension has significant clinical importance. Current invasive and noninvasive plaque imaging has limited spatial resolution which limits accurate definition of microcalcifications in the atherosclerotic plaques. We describe a new imaging technique with high spatial resolution, based on confocal microscopic analysis, using a dedicated software which allows automatic characterization of microcalcifications and quantitative assessment of their extent and localization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
