Mycotic pseudoaneurysms of the ascending aorta are rare in patients undergoing coronary artery bypass graft surgery and are usually caused by Staphylococcus aureus. We describe a patient with a mycotic pseudoaneurysm of the ascending aorta at the proximal vein graft anastomosis site after coronary artery bypass grafting. Cultures from the saphenous vein harvest site and from the aneurysm sac obtained intraoperatively during repair of the pseudoaneurysm grew Pseudomonas aeruginosa. Treatment included femorofemoral bypass and hypothermic circulatory arrest with in situ patch repair. The patient was given ceftazidime and gentamicin intravenously for 2 weeks, then ceftazidime alone for 6 weeks. Thereafter, he began taking ciprofloxacin orally for chronic suppression. He was doing well at 18-month follow-up. 相似文献

Here, we present the case of ruptured intercostal artery pseudoaneurysm two months after blunt thoracic trauma. Ruptured aneurysm hemorrhaged into the retroperitoneal space due to adhesion in the intrathoracic space. We unsuccessfully embolized the aneurysm during an angiographic procedure and performed the aneurysmectomy, removing the hematoma, using a retroperitoneal approach. Ruptured intercostal artery pseudoaneurysm after blunt thoracic trauma may have caused the delayed life-threatening hemorrhage. 相似文献

Most left ventricular inferior wall aneurysms are classified as false, and they have a narrow neck and exhibit rapid flow. Inferior wall pseudoaneurysms that develop soon after primary percutaneous intervention and coronary artery bypass grafting for acute myocardial infarction are rare. We report the case of a 64-year-old man who had a wide-necked left ventricular inferior wall pseudoaneurysm that developed soon after surgery for an acute myocardial infarction and post-infarction mitral regurgitation that occurred as a mechanical complication. The surgery consisted of coronary artery bypass grafting and mitral valve replacement. After the surgery, congestive heart failure developed. At reoperation, we found a large pseudoaneurysm that had caused tearing of the chordae tendineae of the posterior mitral leaflet and scarring around the inferior wall defect. The inferior wall defect had formed the wide neck of the left ventricular pseudoaneurysm. We excised the pseudoaneurysm and the scar tissue and attached a small patch to the defect such that it decreased the left ventricular dimension. Our patient survived the surgery and recovered completely. In patients with acute myocardial infarction, left ventricular pseudoaneurysms can occur soon after coronary artery bypass grafting and surgery for a complication such as mitral valve regurgitation. When a large portion of the left ventricular wall is infarcted and its removal would create a smaller cavity with compromised output, we recommend ventricular reconstruction by patch placement. 相似文献

A 56-year-old man complained of dyspnea and cough 9 days after coronary artery bypass grafting. Chest radiography showed opacity and left lung collapse. Following removal of clots from the pleural cavity by videothoracoscopy, he recovered without further incident. Video-assisted thoracic surgery is a feasible and safe option in the management of early hemothorax. 相似文献

One month after a successful angioplasty, one of our patients developed a new aneurysm in the right coronary artery (RCA). The aneurysm was characterized as a pseudoaneurysm by the use of intravascular ultrasound (IVUS). A stenosis that was not well seen by angiography was better depicted by IVUS. Both the pseudoaneurysm and the stenosis were successfully treated with a second angioplasty and stenting with a covered stent. Delayed development of pseudoaneurysms after dissection is an uncommon, but possible complication after angioplasty. In this case IVUS was useful for accurate characterization of the aneurysm. The use of covered stents may become a clinically useful method for treating coronary pseudoaneurysms. Cathet. Cardiovasc. Intervent. 47:186–190, 1999. © 1999 Wiley-Liss, Inc. 相似文献

A 50-year-old man developed recurrent angina 1 year after coronary artery bypass surgery. The patient was found to have a large fistula involving branches of the internal mammary artery graft and the left pulmonary artery. In the absence of another clear cause for the patient's symptoms, we speculated that our patient's angina and abnormal stress nuclear study were due to coronary steal. In patients with a history of coronary bypass grafting, fistula formation between graft and native vessels should be considered as a possible cause of early recurrent angina. 相似文献

Massive isolated chylopericardium is a rare postoperative complication of coronary artery bypass surgery. In the following case, massive chylopericardium developed after a coronary artery bypass procedure in which the left internal mammary artery was used for revascularization. The chylopericardium resulted from direct trauma to the thoracic duct during mobilization of the left internal mammary artery to its origin at the subclavian artery. With adequate drainage, the problem was resolved. In cases in which drainage persists, ligation of the thoracic duct may be necessary. 相似文献

Dopexamine hydrochloride, a dopamine analog with specific beta 2 adrenergic and DA1 dopaminergic receptor activity, was evaluated in a prospective study including 20 patients undergoing coronary artery bypass grafting. Shortly after admission to the intensive care unit, increasing doses of dopexamine hydrochloride (1.0, 2.0, 4.0, 6.0, 8.0 and 10.0 micrograms/kg/min) were administered as continuous infusion at 20-minute intervals. Hemodynamic monitoring revealed that dopexamine hydrochloride causes a significant decrease in systemic vascular resistance and a significant increase in cardiac output and heart rate, even at lower dose levels (1.0 micrograms/kg/min). At higher dose levels (greater than or equal to 2.0 micrograms/kg/min), adverse effects such as systolic hypertension and tachycardia were observed. Shunt fraction increased significantly during dopexamine hydrochloride administration, probably due to the increase in cardiac output. It is concluded that dopexamine hydrochloride is a potent vasodilating agent at lower dose levels and is of potential benefit to patients with compromised myocardial function after coronary artery bypass grafting. Higher dose levels may cause unwanted side effects, which might be explained by various mechanisms such as norepinephrine uptake inhibition. 相似文献

老年冠心病患者冠状动脉旁路移植术后神经系统并发症 总被引:1,自引:0,他引:1
目的探讨非体外循环下冠状动脉旁路移植术(OPCAB)后患者神经系统并发症(NC)的种类、发生率、危险因素和防治方法。方法收集北京安贞医院2010年6~10月入院行OPCAB的82例老年患者进行前瞻性研究。术前收集NC危险因素,手术前后进行神经系统查体和头颅320排CT脑灌注检查,术后进行神经系统查体确认有无NC的发生。根据术后是否发生NC分为NC组和非NC组,组间进行危险因素单因素分析。结果NC总发生率为17.01%(14/82),无死亡病例,其中术后认知功能障碍(POCD)发生率为14.63%(12/82),焦虑、抑郁的发生率为6.10%(5/82),缺血缺氧性脑病发生率为3.66%(3/82),缺血性脑血管病发生率为1.22%(1/82);NC组与非NC组间进行既往史单因素分析显示,术后NC组脑卒中病史、CT平扫示病灶、糖尿病病史与非NC组相比,有统计学差异;CT脑灌注检查提示,两组脑灌注达峰时间有统计学差异。结论对于行OPCAB患者,应重视术前筛查,完善实验室检查、脑灌注检查等,有助于术前筛查出术后发生NC的高危患者,以给予相应的预防治疗;OPCAB对神经系统而言相对安全但仍需要更多资料进一步研究。 相似文献
