An 81 year-old man had persistent lumbar pain, abdominal pain, and abdominal distension for a week was acutely admitted to our hospital. An enhanced computed tomography scan showed a ruptured infrarenal abdominal aortic aneurysm and a left-sided inferior vena cava. We successfully performed emergency abdominal aortic reconstruction, though we needed temporary abdominal closure with a vinyl sheet for 3 days for fear of abdominal compartment syndrome. He recovered uneventfully and was discharged 27 days after surgery. Left sided inferior vena cava is a rare anomaly of the inferior vena cava and we review the relevant literature here.
A 61-year-old man had a Stanford type A acute aortic dissection, and the total aortic arch was replaced with 22-mm knitted Dacron graft in 1996. In 2006, he underwent mitral valve replacement and tricuspid valve repair due to severe mitral and tricuspid valve regurgitation. Although preoperative computed tomography (CT) scan suggested pseudoaneurysm around the Dacron graft replaced with aortic arch, it could not be repaired concomitantly. Four months later, in view of the technical difficulties of an open surgical procedure, the prosthetic graft failure was repaired by endovascular stent graft consisting of a Gianturco Z stent covered with an UBE woven Dacron graft. However, during a follow-up, aneurysm sac diameter increased without any sings of endoleak in follow-up CT scans. Redo endovascular stent graft placement using a Gore-TAG device was performed. Subsequently, shrinkage of the pseudoaneurysmal sac could be observed.
A 78-year-old man presented with back pain and shock and was transferred to our hospital. Computed tomography showed a ruptured aortic dissection in which the false lumen was thrombosed with an ulcer-like projection, and the mid-esophagus was shifted to the right due to a mediastinal hematoma. He underwent emergency thoracic endovascular aortic repair of the descending thoracic aorta. One week later, esophageal necrosis occurred, and he died of mediastinitis and sepsis on postoperative day 16. Although esophageal necrosis is a rare and fatal complication after thoracic endovascular aortic repair, a management strategy has not yet been established.
We report a 6-year-old boy with no major disease history or allergic conditions initially presented with pneumonia, progressed to acute respiratory distress syndrome and acute myocarditis caused by pandemic 2009H1N1 influenza diagnosed with RT-PCR testing, successfully managed with mechanical ventilation and percutaneous cardiopulmonary support system. Marked transient elevation of IgE in acute phase of the disease and the subsequent diagnosis of atopic asthma in our patient suggested a possible role of an underlying allergic condition in the clinicopathological process. Critically ill 2009H1N1-infected patient with acute respiratory failure should carefully be physiologically monitored together with serial assessment of biomarkers aiming at a favorable cardiac outcome by giving the timely diagnosis and intervention.
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.
