Case Reports
[Right-sided patent ductus arteriosus with a right aortic arch and right descending aorta].
We experienced an extremely rare anomaly, i.e. right-sided persistent ductus arteriosus with a right aortic arch and right descending aorta. Reviewing the literature, we found only two cases clinically reported in Japan as far as we know. The diagnosis was established by angiography and MRI. We treated the patient successfully through right thoracotomy.

We have employed hypothermic retrograde total body perfusion via the caval cannulae as a supportive measures to protect the brain and other systemic organs in operations for aortic arch aneurysms or acute aortic dissection. But occasionally unsatisfactory results ensued, because competent valves located in the internal jugular vein near the jugulo-subclavian junction may block retrograde blood flow to the brain from the caval cannula. To cope with this problem, we designed an easy and safe method to cannulate the internal jugular vein transatrially utilizing guidewire and central venous catheter, and thereafter we have used this technique clinically and obtained good results.
