Occlusion of the true lumen at the ascending aorta with chronic type A aortic dissection

<p>Management of acute Stanford type A aortic dissection remains a major surgical challenge. Directly cannulating the ascending aorta provides a rapid establishment of cardiopulmonary bypass but consists of risks such as complete rupture of the aorta, false lumen cannulation, subsequent malperfusion and propagation of the dissection.</p><p>We describe a technique of cannulating the ascending aorta in patients with acute aortic dissection that can be performed rapidly in hemodynamically unstable patients under ultrasound-epiaortic and transesophageal (TEE) guidance.</p>

Purpose: To describe the combined use of a tubular stent-graft for the ascending aorta and an inner-branched arch stent-graft for patients with acute type A aortic dissection. Technique: The technique to deploy these modular, custom-made stent-grafts is demonstrated in 2 patients with acute DeBakey type I aortic dissections and significant comorbidities precluding open surgery. Both emergent procedures were made possible by the availability of suitable devices manufactured for elective repair in other patients. After preliminary carotid-subclavian bypass, a long Lunderquist guidewire was introduced from the right femoral artery to the left ventricle for delivery of the Zenith Ascend and Zenith Branched Arch Endovascular Grafts under inflow occlusion. Bridging stent-grafts were delivered to the innominate and left common carotid arteries to connect to the 2 inner branches; the left subclavian artery was occluded. Both cases were technically successful and resulted in exclusion of the false lumen in the ascending aorta. The operating and fluoroscopy times did not exceed those of comparable elective procedures. The patients were rapidly extubated shortly after the procedure and without serious immediate complications. One patient survived 11 months with a satisfactory repair; the other succumbed to complications of recurrent pneumonia after 23 days. Conclusion: Endovascular treatment of patients with acute type A aortic dissection using a combination of tubular and branched stent-grafts in the ascending aorta is feasible and offers an alternative strategy to open surgery.

Aortic Dissection Type A

Background: The choice of arterial inflow for acute Stanford type A aortic dissection repair remains controversial. The axillary artery should be considered as first choice for cannulation, but this technique is time-consuming. The ascending aortic cannulation provides antegrade perfusion and can be performed rapidly but there are several concerns such as aortic rupture, extension of dissection, and false lumen cannulation. Objective: To compare the establishment time of cardiopulmonary bypass (CPB) and postoperative outcomes of the two cannulation techniques that provide antegrade perfusion, which was direct true lumen cannulation on the dissected ascending aorta using epiaortic ultrasound-guided and axillary artery cannulation in Siriraj Hospital. Materials and Methods: The authors retrospectively reviewed all the 30 cases of acute aortic dissection type A using two different cannulation methods performed between February 2011 and May 2017. Direct true lumen ascending aortic cannulation was performed using the epiaortic ultrasound-guide with Seldinger technique in 12 patients, and axillary artery cannulation was performed in 18 patients. Results: The direct true lumen ascending aortic cannulation was safely performed in all patients. None of them had aortic rupture. Skin incision to CPB time was significantly faster in the epiaortic ultrasound-guided ascending aortic cannulation group at 29±8 versus 49±14 minutes (p<0.001). The 30-day mortality and postoperative adverse events, such as ischemic stroke, acute kidney injury, visceral organ and limb malperfusion showed no statistically significant difference from the axillary artery cannulation method. Conclusion: Epiaortic ultrasound-guided true lumen cannulation of ascending aorta in the treatment of acute aortic dissection type A is safe and feasible. Skin incision to CPB time can be performed faster and provided good outcome compared to the axillary artery cannulation technique.

Acute Dissection

AbstractStanford Type A aortic dissection is a rapidly progressing disease process that is often fatal without emergent surgical repair. A small proportion of Type A dissections go undiagnosed in the acute phase and are found upon delayed presentation of symptoms or incidentally. These chronic lesions may have a distinct natural history that may have a better prognosis and could potentially be managed differently then those presenting acutely. The method of repair depends on location and extent of the false lumen, as well as involvement of critical structures and branch arteries. Surgical repair techniques similar to those employed for acute dissection management are currently first-line therapy for chronic cases that involve the aortic valve, sinuses of Valsalva, coronary arteries, and supra-aortic branch arteries. In patients with high-risk for surgery, endovascular repairs have been successful, and active development of delivery systems and grafts will continue to enhance outcomes. We present two cases of chronic Type A aortic dissection and review the current literature.
