Surgical treatment for chronic type A aortic dissection and aortic regurgitation in a patient with a tracheostoma

The reimplantation of anomalous aortic origin of the right coronary artery under lower mini-sternotomy

The patient was 28-year-old male. He was suffered from chest pain at rest. He was diagnosed with AAORCA (anomalous aortic origin of the right coronary artery) by emergency catheter. Myocardial scintigraphy indicated ischemic changes in the right coronary artery region, so surgery was the plan. Reimplantation was selected because the coronary artery computed tomography showed little intramural travel and mild coronary artery stenosis. The surgery was performed under lower mini-sternotomy to facilitate early return to work. The patient had a good postoperative course, and was discharged from the hospital postoperative Day 11 after rehabilitation. We report a case of the right coronary artery reimplantation with lower mini-sternotomy for AAORCA.

Total arch replacement with both frozen elephant trunk and transthoracic aorto-axillary extra-anatomical bypass through partial sternotomy for acute aortic dissection in a tracheostomy patient

Median sternotomy near an existing tracheostoma risks deep sternal wound infection after cardiac surgery. We present herein a case of acute type A aortic dissection in a patient with a permanent tracheostoma after laryngectomy. Total arch replacement with both frozen elephant trunk and extra-anatomical bypass for supra-aortic trunks was performed through T-shaped partial sternotomy, resulting in recovery without deep sternal wound infection.

Total arch replacement in a patient with a tracheostoma through a reverse L-shaped partial sternotomy

A conventional median sternotomy in a patient with a tracheostoma is susceptible to postoperative mediastinitis or graft infection after total arch replacement (TAR). An optimal surgical procedure has still not been established to circumvent these complications in such patients. We report a successful case of a 74-year-old man with a tracheostoma who received TAR through a reverse L-shaped partial sternotomy. This incision was simple and enabled us to secure an adequate operative field similar to that of a conventional median sternotomy. The patient was discharged without any evidence of infection or any other complications.

Aortic Hemiarch Replacement through a J-Shaped Lower Partial Sternotomy

Minimally invasive cardiac surgical techniques include the use of partial sternotomy for aortic valve and mitral valve replacement. Partial sternotomy is associated with less pain, better chest and upper-sternal stability, shorter hospital stays, and faster recoveries. However, aortic arch operations are still typically performed through median sternotomies. We describe the case of a 77-year-old woman who underwent elective hemiarch replacement because of an asymptomatic ascending aortic aneurysm. She requested a minimal incision. Our J-shaped partial lower sternotomy adequately exposed the proximal aorta and enabled all cannulations to be performed through the sternotomy. The patient had an uncomplicated postoperative course. We think that a partial sternotomy for ascending aortic and hemiarch replacement can be considered in selected patients for whom the procedure's benefits are important.

Total arch replacement for a subacute type A dissection in a patient with a terminal tracheostoma after total laryngectomy: report of a case

Standard full median sternotomy for total arch replacement in tracheostomy patients may lead to mediastinitis and graft infection. Several approaches for typical cardiac surgery, including a T-shaped sternotomy, have been used in patients with both terminal and transient tracheostomas; however, these procedures offer inadequate surgical exposure of the arch vessels. We herein report the case of a 67-year-old man with a subacute type A aortic dissection with a terminal tracheostoma after total laryngectomy, who successfully underwent total arch replacement by a fourth intercostal thoracotomy performed using an anterior bilateral approach and the arch-first technique. To our knowledge, this is the first report of a case of total arch replacement in a patient with subacute aortic dissection and a terminal tracheostoma.
