ABSTRACT
Intestinal ultrasound (IUS) is a promising modality for the management of inflammatory bowel disease (IBD) and has the potential to particularly contribute in monitoring disease activity, an advantage crucial for optimizing the therapeutic strategy. While many IBD physicians appreciate and are interested in the use of IUS for IBD, currently only a limited number of facilities can employ this examination in daily clinical practice. A lack of guidance is one of the major barriers to introducing this procedure. Standardized protocols and assessment criteria are needed such that IUS for IBD can be considered a feasible, reliable examination in clinical practice, and multicenter clinical studies can be conducted for further clinical evidence of the application of IUS in IBD for best patient care. In this article, we provide an overview of how to start IUS for IBD and introduce basic procedures. Furthermore, IUS images from our practice are provided as a color atlas for understanding sonographic findings and scoring systems. We anticipate this “first aid” article will be helpful to promote IUS for IBD in daily practice.
ABSTRACT
The patient was a 57-year-old man who, in 1973, at 19 years of age, had undergone mitral valve replacement for mitral valve stenosis using a Björk-Shiley Delrin (BSD) valve. When the patient visited our hospital, he was living in an assisted-living facility due to paresis of the right side of the body, dysarthria, and other sequelae of cerebral infarction. The patient was referred to and visited our hospital with a chief complaint of chest pain in 2011, 38 years after the BSD valve was implanted. In 2012, mitral valve re-replacement, aortic valve replacement, and tricuspid annuloplasty were performed for congestive heart failure associated with prosthetic valve failure, combined aortic stenosis and insufficiency, and tricuspid insufficiency, which were identified by transesophageal echocardiography. The patient's postoperative course was generally favorable. The disc of the resected prosthetic valve showed a groove and bidirectional cracks caused by wear, and its condition suggested a risk of potential rupture. Transthoracic echocardiography on admission showed mild to moderate prosthetic transvalvular regurgitation, and the symptoms were therefore unlikely to have resulted from the prosthetic valve failure alone at this time. Consequently, it was considered that the heart failure was attributed to the prosthetic transvalvular regurgitation caused by the disc abnormalities in addition to the combined valvular disease by transesophageal echocardiography. In this case, detailed investigation of the heart failure by transesophageal echocardiography led to the discovery of prosthetic valve abnormalities, thus enabling the prevention of a serious cardiac accident due to disc rupture. Detailed examination by transesophageal echocardiography is essential, and early surgical intervention should also be considered if transthoracic echocardiography suggests even a minor prosthetic valve abnormality in a patient who has had this prosthetic valve implanted for such a long time.
ABSTRACT
A 77-year-old woman with a medical history of myocardial infarction had a medical check-up at a local clinic. She reported sensation of abdominal distension which had appeared 6 months previously. Computed tomography demonstrated a very large ovarian tumor concomitant with an abdominal aortic aneurysm with a maximum diameter of 68 mm, and she was referred to our hospital. We performed a simultaneous extirpation of the ovarian tumor and abdominal aneurysm prosthetic graft replacement. The patient was discharged 13 days postoperatively after an uneventful postoperative course. The histopathological diagnosis of the ovarian tumor was mucinous cystadenoma. We reviewed the surgical procedures for similar cases of concomitant disease, and found that reports of surgical cases of simultaneous huge ovarian tumor extirpation and abdominal aneurysm prosthetic graft replacement are rare.
ABSTRACT
A 7-year-old boy suffered from isolated interruption of the aortic arch without any other complications or cardiovascular malformations. Cardiac murmur, which had been apparent since one month of age, had been left untreated because of the absence of any symptoms of heart failure. Isolated interruption of the aortic arch was noted during a routine physical examination at school and the patient was referred to our hospital for a complete medical evaluation. Blood-pressure difference was recognized not only between the right side and the left side of the upper extremities but also between the upper and lower extremities. On the basis of the results obtained via magnetic resonance angiography (MRA) and aortography, a definitive diagnosis of isolated interruption of the aortic arch was made. Reconstruction of the aortic arch by synthetic implant was indicated. The blood-pressure difference disappeared and the postoperative course was satisfactory.
