Hybrid Repair of Concomitant Descending Thoracic and Abdominal Aortic Aneurysms Using Antegrade Visceral Debranching from the Ascending Aorta / 日本心臓血管外科学会雑誌

A 76-year-old man had increasing thoracic and abdominal aortic aneurysms. First, endovascular repair was performed on the thoracic descending aorta, but type Ib endoleak persisted due to severe aortic calcification. Additional treatment was planned since the maximum diameter of the thoracic and abdominal aortic aneurysms had increased to 75 and 70 mm, respectively. Due to the fact that aortic calcification was present from the aortic arch to the bilateral iliac arteries, which is sometimes referred to as porcelain aorta, conventional open thoracoabdominal aortic repair or hybrid repair using retrograde debranching seemed impossible. Therefore we performed antegrade visceral debranching from the ascending aorta followed by endovascular thoracoabdominal aortic repair successfully. For the thoracoabdominal aortic aneurysms which present difficulty in performing conventional open surgical repair or hybrid repair with retrograde debranching from the iliac artery. This technique can be an effective alternative strategy, but still needs further investigation, including its indications, due to the high surgical stress associated with the procedure.

Sequential Hybrid Repair of Aorta and Bilateral Common Iliac Arteries Secondary to Chronic Aortic Dissection with Extensive Aneurysmal Degeneration in a Marfan Patient

Marfan syndrome is a connective tissue disorder associated with aortic dissection, aneurysmal degeneration and rupture. These cardiovascular complications represent the main cause of mortality, therefore repair is indicated. We present a 35-year-old woman who experienced acute onset of chest pain. Her imaging revealed a chronic DeBakey type I dissection with aortic root dilation and descending thoracic aneurysmal degeneration. She underwent a Bentall procedure and endovascular exclusion of the descending thoracic aortic aneurysm. She was closely followed and 2 years later a computed tomography angiography (CTA) revealed the aneurysmal degeneration of the thoracoabominal aorta and bilateral iliac arteries. The patient underwent a composite reconstruction using multi-visceral branched and bifurcated Dacron grafts. At 5 years from her last surgery, a CTA revealed no new dissection or further aneurysmal degenerations. Aortic disease in Marfan patients is a complex clinical problem that may lead to secondary or tertiary aortic reconstructions; close follow-up is mandatory.

Hybrid Repair of Type III Thoracoabdominal Aortic Aneurysm with Pre-Occluded Visceral Arteries / 대한혈관외과학회지

As experiences with endovascular aortic devices increases over time, hybrid repair for the treatment of thoracoabdominal aortic aneurysms (TAAA) by using a combination of thoracoabdominal endovascular aneurysm repair and visceral revascularization has been reported with acceptable result. A 55-year-old man with type III TAAA involving visceral arteries has been treated successfully with tube stent-graft followed by right renal revascularization that was facilitated by a rare anatomic configuration. The authors present a type III TAAA patient with rare anatomic configuration of the visceral arteries successfully treated with hybrid endovascular-surgical TAAA repair.
