Peliosis hepatis is an extremely rare condition that may cause fatal hepatic hemorrhage and liver failure. We report a case of liver hemorrhage due to idiopathic peliosis hepatis. A 60-year-old woman was admitted to our hospital with slight right hypochondriac pain. She went into hemorrhagic shock, and computed tomography (CT) showed multiple low-density areas in the right liver with massive subcapsular blood collection. Selective transfemoral arteriography of the celiac artery revealed no signs of vascular malformation or tumor stain, but showed signs of pooling in the right posterior segmental artery. The artery was embolized with particles of gelatin sponge, and hemostatic control was successful. Although peliosis hepatis is extremely rare, the diagnosis is significant because of its urgent clinical status, and transarterial embolization is a useful and minimally invasive procedure for liver hemorrhage due to peliosis hepatis.
We describe a case of a 63-year-old woman who presented with spontaneous dissection of the innominate and left common carotid arteries arising from a common trunk, so-called "bovine aortic arch." The entry tear was seen in the common trunk at the origin of the innominate artery with no dissection extending into the aortic arch or the ascending aorta. The dissection was resected and total arch replacement was performed considering the aortic wall fragility complicated by the dissection.
We report a case of isolated pulmonary valve endocarditis in a 47-year-old woman without predisposing factors. She had episodes of low-grade fever and non-productive cough and was initially diagnosed with bacterial pneumonia. With antibiotic treatment, her condition improved transiently, but she had repeated respiratory events. Forty days after her first visit, she complained of severe dyspnea. Echocardiography revealed a large vegetation adhering to the pulmonary valve and she was diagnosed with isolated pulmonary valve endocarditis. Surgical treatment was selected because antibiotic treatment was not effective. The main pulmonary artery was transected above the annulus and the infected valve was excised. To avoid contact of the prosthetic valve with the infected pulmonary annulus, a stentless bioprosthesis was interposed between the transected parts of the pulmonary trunk. Two years after the surgery, the patient is stable with no sign of infection.
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.
