RESUMO
A 71-year-old woman underwent repair of a ventricular septal perforation due to myocardial infarction by the extended sandwich patch technique 5 years ago. She was discharged from the hospital without complications. During the follow-up period, a ventricular apical aneurysm was found on contrast-enhanced computed tomography and transthoracic echocardiography. Since the aneurysm had enlarged gradually and a thrombus was found in it, repairing surgery was indicated. The patient was initiated on cardiopulmonary bypass after dissection of the adhesions of the previous surgery, and a longitudinal incision was made on the left side of the left anterior descending artery under cardiac arrest to remove the aneurysm. A large amount of thrombus was found inside the aneurysm. The thrombus was removed, Dor surgery was performed with a circular Hemashield patch. Reports of ventricular apical aneurysm after myocardial infarction in a remote period are rare. It is necessary to perform surgical intervention as soon as possible to prevent free wall rupture as well as cerebral infarction.
RESUMO
The number of surgical treatments for acute aortic dissection in octogenarians is increasing. They should return to their daily life as soon as possible after the operation without any complications. Some literature reported that minimally invasive cardiac surgery (MICS) helps quick recovery for the patients. We report a case of minimally invasive ascending aorta replacement for Stanford type A chronic thrombosed aortic dissection in an octogenarian to help quick recovery. An 81-year-old man was admitted in our hospital suffering from chest and back pain. Enhanced CT scan showed Stanford type A acute thrombosed aortic dissection. The diameter of ascending aorta was 45 mm and the diameter of false lumen was 7 mm. Therefore we decided on medical treatment for this patient according to the guideline. After four weeks medical treatment, ascending aorta was dilated to 49 mm and the false lumen also expanded to 9 mm. He underwent minimally invasive ascending aorta replacement to help quick recovery considering his age. He was discharged 11 days postoperatively without any complications. MICS offers a better cosmetic result, less blood loss, less pain, better respiratory function and quick recovery. Thus, minimally invasive operation for the elderly is also very satisfactory.
RESUMO
A 60-year-old man, who had undergone mitral valve repair with quadrangular resection of the posterior mitral leaflet and ring annuloplasty with a Cosgrove-Edwards ring, developed severe mechanical hemolytic anemia. Doppler echocardiography showed only mild residual mitral regurgitation, but turbulent jet was directed toward the annuloplasty ring. Because of unremitting hemolysis requiring multiple transfusions and the occurrence of renal dysfunction, he underwent replacement of the mitral valve with a St. Jude Medical valve. Inspection of the annuloplasty ring at operation showed no evidence of dehiscence, but the area of the annuloplasty ring adjacent to the posteromedial commissure showed no endothelization. After the reoperation, the hemolysis and general condition immediately improved. This experience made us realize the possibility that a high-velocity regurgitant jet toward the cloth-covered annuloplasty ring, even if it mild, can cause severe hemolysis.
RESUMO
A 71-year-old man was admitted complaining of abdominal pain. Contrast enhanced CT scan showed bilateral inflammatory common iliac artery aneurysms and encasement of bilateral ureters with perianeurysmal fibrosis. Drip infusion pyelography (DIP) showed bilateral hydronephrosis. After insertion of ureteral stents, Y-graft replacement and bilateral ureterolysis were performed successfully in spite of adhesion of the ureters to the aneurysmal wall. Postoperative DIP showed good passage in ureters and improvement of hydronephrosis. We would like to emphasize the usefulness of preoperative ureteral stenting for identification and mobilization of ureters.
