Prevention of Embolization in Concomitant Endovascular Therapy for Thoracic and Abdominal Aneurysms with Severely Atheromatous Aorta.

A 74-year-old man with multiple aortic aneurysms and shaggy aorta was simultaneously treated by conventional open repair for an abdominal aortic aneurysm and endoluminal stent grafting for a thoracic aortic aneurysm. We performed intermittent clamping of the visceral and carotid arteries under an extracorporeal circulation circuit without a blood flow pump, which lead to the avoidance of embolization in spite of the disadvantage of endoluminal stent grafting for atheromatous aorta.

Video-assisted endoscopic resection of left ventricular papillary fibroelastoma through the aortic valve.

Papillary fibroelastoma is a rare, benign cardiac tumor. Surgical resection is indicated to prevent embolization. We herein report a case of a 78-year-old asymptomatic man who was found to have a mobile left ventricular papillary fibroelastoma anchoring deep in the left ventricle by incidental transthoracic echocardiography. The tumor was resected under visualization by a video-assisted rigid endoscope with a flexible head inserted through the aortic valve into the left ventricle. Intraoperative frozen section analysis provided a pathological diagnosis of papillary fibroelastoma. The postoperative course was uneventful. This technique is recommended for the observation and resection of a tumor anchoring deep in the left ventricle and is helpful for avoiding the adverse effects of left ventriculotomy.

[Efficacy of Early Surgical Strategy for Active Infective Endocarditis].

UNLABELLED: The aim of study was to analyze the outcome of aggressive, early surgical intervention to active infective endocarditis (IE) complicated by acute congestive heart failure, uncontrollable infection and large, mobile vegetation and to evaluate the validity of current therapeutic strategy on it's long-term outcome. PATIENTS AND METHODS: We retrospectively investigated surgical outcome of 51 patients who underwent surgical intervention to eradicate intra-cardiac infection and to reconstruct subsequent structural destruction due to active IE performed between 2002 and 2013. Patient's mean age was 56 ± 17 (14~83) years and 36 males, 2 prior cardiac surgery-performed and 2 hemodialysis-dependent renal failure patients were included. All patients were followed on long-term basis. Mean follow up duration was 61 ± 46 (1~164) months. We classified patients into 2 groups according to urgency of surgical intervention:early surgical (ES) group who underwent surgery within 2 weeks from diagnosis of IE and conservative surgical (CS) group who underwent after 2 weeks more from the diagnosis. RESULTS: Two patients died during hospitalization due to low cardiac output syndrome (LOS) for ischemic myopathy after old myocardial infarction and postoperative ischemic colitis (preoperative hemodialysis-dependent patient). Two cerebral infarctions and 1 hemorrhagic transformation of cerebral infarction occurred postoperatively. There was no mediastinal infection and recurrent intracardiac infection postoperatively. On long-term follow up, cumulative survival was 90/79/68% in 1/5/10 years. on ES group and 100/89/79% in 1/5/10 years. on CS group, respectively. Freedom from cardiac death were 100/100/100% in 1/5/10 years. on ES group and 100/100/100% in 1/5/10 years. on CS group, respectively. There were 1 cardiac death(125 months after operation) and 8 non-cardiac deaths on long-term survival. CONCLUSION: Early surgical strategy for active infective endocarditis to prevent IE-related preoperative adverse complications seems to be acceptable.

Direct percutaneous puncture embolization of type II endoleaks using a coaxial technique.

PURPOSE: To demonstrate a coaxial needle technique for direct percutaneous puncture embolization of type II endoleaks. TECHNIQUE: The technique is demonstrated in a 79-year-old woman and an 80-year-old man who developed type II endoleaks after endovascular repair of thoracic and internal iliac artery aneurysms, respectively. Expansion of the aneurysms required additional therapy. Fluoroscopy and cone-beam computed tomography-guided direct percutaneous endoleak sac embolization with n-butyl-2-cyanoacrylate (NBCA)-lipiodol was performed using the coaxial technique, which resulted in complete embolization of the endoleak sac. At 6 and 3 months after embolotherapy, respectively, the NBCA-lipiodol filled the endoleak sacs and the communicating channels up to the respective feeding arteries; no enlargement of the aneurysms was observed. CONCLUSION: Direct percutaneous sac embolization using a coaxial technique for type II endoleaks is a feasible treatment and yields good short-term results. More experience with this technique and longer follow-up of these patients is needed.

Short-term and long-term outcomes of octogenarians after off-pump coronary artery bypass surgery.

PURPOSE: Off-pump coronary artery bypass has been reported to be associated with reduced morbidity and mortality after surgical coronary revascularization, especially in high-risk patients. The aim of this study was to clarify the efficacy of off-pump coronary artery bypass for the very elderly patients. METHODS: We compared the outcomes of octogenarians (n = 28, 82 ± 2 years) undergoing off-pump coronary artery bypass and those of the patients <80 years of age (n = 315, 67 ± 9 years) during short- and long-term periods. RESULTS: There was no difference in hospital mortality between octogenarians and the younger cohort (3.8% vs. 0.6%; P = 0.11). A high rate of postoperative complications (e.g., pneumonia, transient renal dysfunction, ventricular arrhythmia) were observed in the octogenarians. The long-term survival (81% at 5 years) and the rate of freedom from cardiac death (92% at 5 years) and from cardiac events (85% at 5 years) were excellent in the octogenarians; they appeared less favorable, however, when compared with the younger group (95%, 98%, and 94% at 5 years, respectively). Most of the cardiac adverse events, including unexplained sudden death, occurred 6 months after the surgery in octogenarians. CONCLUSION: Off-pump coronary artery bypass can be performed safely in octogenarians, with excellent early and late outcomes. Careful postoperative follow-up is required to reduce postoperative long-term adverse events. Off-pump coronary artery bypass is a feasible modality of coronary revascularization for octogenarians.
