BACKGROUND: While autologous split calvarial bone is an ideal graft material in cranioplasty, selection of a donor site can be challenging and limited in the reconstruction of complicated cranial defects. Computer-aided design and manufacturing (CAD/CAM) may improve donor-site harvest and contouring and mitigate operative complications in split calvarial bone graft-based cranioplasty for complex patients, but has not previously been studied in this unique setting. METHODS: In this study, a retrospective review of patients who presented to the institution and underwent split-calvarial bone graft-based cranioplasty using CAD/CAM to optimize reconstruction of full-thickness cranial defects ≥30 cm was performed...

BACKGROUND: Partial anomalous pulmonary venous return is a rare congenital cardiac anomaly that usually involves the right pulmonary vein and an atrial septal defect. Isolated partial anomalous pulmonary venous return with an intact atrial septum is even rarer, and this condition is usually treated surgically in younger patients. We describe isolated partial anomalous pulmonary venous return in a 65-year-old woman who was treated by caval division with pericardial patch baffling through a surgically created atrial septal defect and reconstruction of the superior vena cava using a prosthetic graft...

A 45-year-old woman was admitted to our hospital because of chest pain on exertion. She was diagnosed to have an anomalous aortic origin of the right coronary artery(RCA) arising from the left sinus of Valsalva, passing between the aorta and the main pulmonary artery. Exercise treadmill test demonstrated significant depression of ST segments in leads II, III and aVF.Because medical treatment was ineffective, reimplantation of the RCA was performed. Dysfunction of the reimplanted RCA occurred, however 3 hours after surgery, and emergency coronary artery bypass grafting was performed using a saphenous vein graft to the RCA...

A 40-year-old man presented to our hospital with fever and slight palpitation. The echocardiogram revealed bicuspid aortic valve, massive aortic regurgitation, and aneurysm of Valsalva sinus. Operative findings showed an aortic root pseudoaneurysm originating just below the avulsion of the right to left commissure. The orifice was closed with a part of a woven vascular graft, and the aortic valve was replaced with a mechanical valve. There was no sign of marked inflammation, although pathophysiologic findings indicated infective endocarditis...

Fereydoun Pourdanesh, Noorahmad Latifi, Fatemeh Latifi
Among different graft materials for craniofacial reconstruction, calcium phosphate cements have the advantages of alloplastic grafts and wide use. The authors report a case of foreign body reaction following frontal reconstruction with JectOS (an injectable calcium orthophosphate cement; Kasios) and reviewed the literature on complications of this material after craniofacial reconstruction from 2002 to 2017. Complications were categorized into two groups: immunologic reactions (consisting of seroma collection, chronic sinus mucosa swelling, and foreign body reaction) and non-immune events (infection, fragmentation, and ejection)...
