Simultaneous Total Debranching TEVAR for Aortic Arch Aneurysm and Redo-CABG in a Patient with a Functional Internal Mammary Artery Graft / 日本心臓血管外科学会雑誌

Treating a thoracic aortic aneurysm (TAA) after coronary artery bypass graft (CABG) surgery requires an appropriate surgical procedure to preserve the functional graft. We present a case of hybrid procedure of thoracic endovascular aortic repair combined with a redo off-pump CABG via median sternotomy. The patient was a 76-year-old man with a history of CABG and abdominal aortic replacement in a different country. Chest computed tomography revealed a saccular-shaped aortic aneurysm in the distal aortic arch with diameter of 5.6 cm. Coronary angiography revealed theLIMA graft was patent but anastomosed to the diagonal branch and the left anterior descending artery (LAD) was totally occluded and was opacified through the right coronary artery. Significant ischemic change in the anteroseptal wall suggested a requirement of surgical revascularization of LAD. The chest was opened via re-midsternotomy. Then the 3 arch vessels were reconstructed with a trifurcated artificial graft attached to the ascending aorta and coronary artery bypass grafting was performed on the beating heart. Finally, the aneurysm was excluded by introducing a stent graft through the graft to zone 0. The patient's postoperative course was uneventful and he was discharged on postoperative day 16. A hybrid procedure via median sternotomy was useful in the surgery for TAA with the functional LIMA after CABG.

Imaging diagnosis and interventional radiology in systemic vasculitis with particular emphasis on Takayasu arteritis: Part 2 / 中国介入影像与治疗学

In part 1 of this article, clinical features and imaging findings of Takayasu arteritis (also known as aortitis syndrome) were described in detail. In part 2, treatment of Takayasu arteritis will be first described and discussed. This will be followed by description of clinical features and imaging findings of other systemic vasculitis. Comments on interventional radiology for systemic vasculitis will also be made.

Imaging diagnosis and interventional radiology in systemic vasculitis with particular emphasis on Takayasu arteritis: Part 1 / 中国介入影像与治疗学

This is a review article describing some new and interesting aspects in the diagnosis and treatment in systemic vasculitis and demonstrating several cases that we have encountered. Particular emphasis will be put on Takayasu arteritis (also known as aortitis syndrome) most commonly observed in Japan and other oriental countries. CT and MRI better demonstrate the vessel wall abnormality of Takayasu arteritis than angiography. Importance of plain chest radiograph should also be kept in mind; it could provide a clue in the diagnosis of Takayasu arteritis in its early stage.

A Case of Marfan's Syndrome with Repeated Occurrence of Acute Aortic Dissection during Treatment / 日本心臓血管外科学会雑誌

A 26-year-old man with Marfan's syndrome suffered aortic dissection repeatedly during hospitalization. He was admitted with a diagnosis of annuloaortic ectasia with severe aortic regurgitation. A type A aortic dissection occurred after diagnostic angiography. Three weeks after the onset of the dissection, an aortic root replacement in combination with a total arch replacement was performed. Eight months later, residual dissection in the descending thoracic aorta was replaced with distal perfusion by a temporary bypass from the left subclavian artery to the descending thoracic aorta. At the termination of the operation, abdominal aortic dissection occurred with acute bilateral limb ischemia, which was treated with abdominal aortic intimal fenestration. He recovered uneventfully and was discharged 3 weeks after operation. In light of our experience, because of vascular fragility, great care should be taken in treating patients with Marfan's syndrome to avoid iatrogenic aortic dissection.
