ABSTRACT
We report the rare case of a 68-year-old man, who was admitted to our hospital with a diagnosis of aortic arch anastomotic pseudoaneurysm, with concomintant aortic root enlargement and coronary artery stenosis. Eleven years previously, at age 56, he underwent total arch replacement with island reconstruction for chronic aortic dissection. We performed redo total arch replacement, aortic root replacement and coronary artery bypass, making use of a cardiopulmonary bypass with cannulation through the right subclavian artery, femoral artery and femoral vein before resternotomy. We also used selective cerebral perfusion. Postoperatively, the patient temporarily required reintubation ; however, he was discharged in good condition on the 50th post-operative day. The case suggests that island reconstruction has the potential to cause an aortic arch pseudoaneurysm, particularly after a long postoperative period of time. Therefore, thorough postoperative care strategy is required. We also need to consider surgical reconstructive techniques which eliminate vascular lesions as much as possible at the time of the primary surgery, particularly in cases of chronic aortic dissection.
ABSTRACT
A 65-year-old woman was referred for progressive dyspnea and leg edema. Physical examination revealed a continuous murmur along the right sternal border. Enhanced computed tomography showed an aneurysm that extended to the right atrium. Aortic angiography confirmed the rupture of the valsalva aneurysm into the right atrium. The patient underwent emergency surgery to close the aneurysm ostium and suture closure of the right atrial fistula. The patient's postoperative course was uneventful.
ABSTRACT
Recently, with the advent of medical devices and minimally invasive operations, endoscopic saphenous vein harvesting (EVH) in coronary artery bypass grafting has been widely accepted. Although EVH has short-term advantages of less wound morbidity and better cosmetic results compared with open vein harvesting (OVH), several studies have demonstrated that the mid- and long-term patency rate of EVH veins is significantly lower than that of OVH veins, therefore the role of EVH is currently controversial. The purpose of this study was to investigate the early results of EVH compared with the OVH group. Between April 2011 and December 2012, 115 consecutive patients underwent coronary artery bypass grafting (CABG) in our institution. Of these, EVH was performed in 62 patients and OVH in 53. In EVH groups, all 50 patients were men, and mean age was 71.3±7.8 years. A total of 211 coronary anastomoses, 109 SVGs anastomoses were assessed for patency postoperatively by angiography or enhanced computed tomography before discharge. The mean vein harvesting time was 26.0±8.1 min, and the mean number of ostial branch tear was 0.34±0.59. The overall SVG patency rates at discharge were 95.4% in EVH and 92% in OVH, respectively (<i>p</i>=0.24). There was a significant reduction in the incidence of leg wound complications in the EVH group (EVH : 1.6% ; OVH : 13.2% ; <i>p</i>=0.038). In conclusion, the short-term result of EVH was satisfactory. EVH reduces leg wound complications compared with OVH.
ABSTRACT
We report 2 cases of successful proximal reoperations after acute type A dissection. Case 1 : A 53-year-old man underwent ascending aorta and aortic arch replacement and aortic valve re-suspension for acute type A dissection with aortic valve regurgitation in 1992. Thirteen years after the first operation, computed tomography demonstrated a Valsalva aneurysm (74 mm) and Doppler echocardiography showed moderate aortic valve regurgitation. Therefore, we performed an operation. We could not locate the dissection in the Valsalva sinus, and the aortic valve cusps had organic change. A David procedure was performed. The postoperative course was uneventful and he was discharged on the 19th postoperative day. Case 2 : A 65-year-old woman underwent ascending aorta replacement and aortic valve resuspension for acute type A dissection with aortic valve regurgitation in 1997, but 11 years after the first operation, computed tomography demonstrated a Valsalva aneurysm (55 mm) and arch aneurysm (65 mm) with stenosis of the innominate vein and she had facial and left arm edema. Doppler echocardiography showed moderate aortic valve regurgitation. We could not find the location of dissection in the Valsalva sinus or aortic arch, and aortic valve cusps had no organic change. A Bentall procedure and total arch replacement were performed and her postoperative course was uneventful.
ABSTRACT
We present a rare case of a 59-year-old-man with a diagnosis of hypertrophic cardiomyopathy (HCM) complicated with left ventricular thrombus. He was admitted to our hospital because of acute re-occlusion of the right brachial artery. Thrombectomy was performed and reperfusion was obtained. Anti-coagulation therapy was started from that day. Four days after surgery, echocardiography revealed mobile thrombus in left ventricular apical aneurysm that was not detected on admission. An emergency thrombectomy and left ventriculoplasty was performed. The patient was discharged 22 days after surgery in good condition.
