ABSTRACT
A 76-year-old man who suffered from consistent back pain was admitted for anti-hypertensive therapy to strictly manage the early thrombosed acute type A aortic dissection (AAAD). On admission, his blood pressure could not be controlled well ; soon he complained of recurrent severe back pain. The second thoracoabdominal enhanced computed tomography revealed the progression of AAAD from DeBakey type II to type I with thrombosed pseudolumen at the descending thoracic aorta ; therefore, emergent surgical intervention by primary central repair was conducted. Paraplegia was diagnosed eight hours after surgery, then cerebrospinal fluid drainage and intravenous administration of Naloxone were started immediately followed by keeping the systemic blood pressure more than 120 mmHg. However, paraplegia had never improved and been persistent with neurological deficit of the lower extremities. We herein report a complicated surgical case of an AAAD patient with paraplegia and review the complex clinical settings.
ABSTRACT
The method of cardioplegic myocardial protection is often controversial for re-cardiotomy after a coronary artery bypass grafting (CABG). A 69-year-old woman with a history of three previous surgeries consisting of closed mitral commissurotomy (CMC), dual valve replacement (DVR), and CABG underwent mitral valve replacement (MVR) and CABG for perivalvular leakage (PVL). As a result, the bilateral coronary ostium and the bypass graft to the right coronary artery (RCA) were totally occluded. The left internal thoracic artery (LITA) graft to the left anterior descending (LAD) coronary artery was the only inflow to the left coronary artery system and the right coronary artery system developed collateral inflow. Cardioplegia was carried out by performing a temporary anastomosis graft on the saphenous vein graft (SVG) in the left anterior descending coronary artery and a new bypass graft in the RCA was used for the administration of cardioplegic solution with no complications. There are various strategies for cardioplegic myocardial protection. The best method should be selected depending on the patient characteristics and condition.
