Background: Massive retracted rotator cuff tears represent a therapeutic dilemma, particularly in the young and middle-aged patients who are not appropriate for a reverse total shoulder replacement. Interposition grafting using human dermal allograft offers an alternative treatment. Methods: A retrospective review of all patients who underwent interposition grafting using human dermal allograft between December 2013 and May 2015 for massive rotator cuff tears at our tertiary referral center was performed. Preoperative and 6 month postoperative magnetic resonance imaging (MRI) assessments were performed in all patients, with postoperative graft integrity being the primary outcome measure. Clinical evaluation was performed using the Oxford shoulder score, Constant score, and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results: The mean age at the time of follow-up was 54 years. On MRI, 84% of grafts were seen to have failed at 6 months. Strength was grossly reduced on the operative side when supraspinatus and subscapularis were tested; despite this, Constant score (mean, 48.2) was comparable to that in the previous reports. DASH and Oxford scores were a mean of 24.94 and 37.16, respectively. Conclusions: Based on these results, in particular the MRI findings, we cannot advocate the use of dermal allograft as an interposition graft for the repair of massive rotator cuff tears.
Mitral Valve Leaflet Aneurysm-Dynamic CT and Echocardiographic Appearances
Heyworth Paul,Bou-Samra John,Shulman Ryan 아시아심장혈관영상의학회 2019 Cardiovascular Imaging Asia Vol.3 No.1
Mitral valve leaflet aneurysm (MVLA) is a rarely encountered pathology with the risk of developing serious complications. We present its imaging appearances in two cases: an 89-yearold female with an incidental finding of both mitral valve leaflet and membranous septal aneurysms during workup for transcatheter aortic valve implantation, and a 48-year-old woman with MVLA secondary to infective endocarditis. As imaging techniques other than echocardiography are being more frequently utilized in the diagnosis of cardiac pathology, this entity may be encountered more often with different modalities. Early diagnosis and intervention are critical to treat this rare and potentially fatal pathology.
