Which graft material is the optimal for treatment of infected aortic aneurysms and infections still a matter controversy. Orthotopic reconstruction with intraoperatively prepared xenopericardial roll grafts without omentopexy was performed as "initial" operation to treat infection or "rescue" infection. Mid-term outcomes were evaluated. Between 2009 2013, orthotopic replacement eight patients (male/female: 6/2; mean age: 69.5 [55–80] yr). Graft material: equine/bovine pericardium: 2/6; type...
Abstract Background Anomalous left coronary artery from the pulmonary (ALCAPA) is a rare congenital anomaly that results in high mortality if untreated. Our aim was to extend our knowledge of histological, angiographic, and clinical characteristics ALCAPA order deepen understanding this entity. Case presentation We were involved assessment, treatment, pathological evaluation two adult patients who rescued ventricular fibrillation then surgically treated establish dual system. Histological...
Abstract OBJECTIVES We conducted this case series to evaluate the feasibility and mid-term outcomes of orthotopic aortic arch reconstruction using xenopericardial grafts treat native arch/arch graft infection. METHODS Between 2010 2023, adopting a multidisciplinary approach, we treated consecutive patients with infection by branched roll replacement tissue filling. The end points study were reinfection graft-related complications such as pseudoaneurysm formation, thromboembolism, stenosis,...
Resection of the infected aorta, debridement surrounding tissue, in situ graft replacement, and omentopexy is standard procedure for treating aortic aneurysms, but question which material optimal still a matter controversy. We recently treated patient with an thoracic aneurysm. The aneurysm was located proximal arch. Because patients had previously undergone abdominal surgery, arch were replaced branched equine pericardial roll grafts. alive well 23 months after operation.
Retrograde cerebral perfusion (RCP) has been used as a cerebroprotective method under hypothermic circulatory arrest (HCA) during aortic surgery. As reported in an animal model 2005, intermittent pressure-augmented-RCP (IPA-RCP) provides more effective than RCP. In 2013, the clinical efficacy of IPA-RCP was described terms outcomes and regional oxygen saturation using infrared spectroscopy. However, state microcirculation not investigated humans. The aim present study to investigate humans...
The standard procedure for treating infected aortic aneurysms is to resect the aorta, debridement of surrounding tissue, in situ graft replacement, and omentopexy. However, question which material optimal still a matter controversy. We recently treated patient with an ascending aneurysm. Because previous abdominal surgery, omentum was unavailable. aorta replaced equine pericardial roll grafts. alive well 29 months after operation.
Retropharyngeal hematoma is a rare form of pharyngeal pathology and can present as acute airway obstruction. Among the many causes retropharyngeal hematoma, thoracic aortic rupture extremely rare. A 78-year-old female with obstruction by secondary to aneurysm was successfully treated total arch replacement open stent-graft insertion. Rupture aorta should be considered but important cause
It is still difficult to create a secure linear conduction block on beating heart from the epicardial side. To overcome this drawback we developed an infrared coagulator equipped with cuboid light-guiding quartz rod. This study was designed electrophysiologically confirm efficacy of new ablation probe using energy in clinical case. The light lamp focused into newly rod, which has rectangular distal exit-plane that allows 30 mm × 10 photocoagulation. Two pairs electrodes were attached right...
We previously demonstrated that infrared coagulator IRK-151 (Lumatec, Deisenhofen, Germany) is capable of creating a transmural lesion while preserving the epicardium and endocardium beating right atrium ventricle in canine model (1). Since original contains 3-sec timer its plastic body not strong enough to tolerate long coagulation times, we modified it by replacing with reinforced heat-resistant substituting digital programmable so would be perform myocardial ablation, conduction block on...
A 78-year-old man, who had previously undergone coronary artery bypass graft surgery, was admitted to our department for treatment of a distal aortic arch aneurysm. total replacement with patent left internal thoracic (LITA) successfully performed without cardiac ischemic or neurological complications. Use retrograde cardioplegia intermittent pressure-augmented cerebral perfusion clamping and dissecting the LITA were effective in myocardial protection.
Central MessageThis is the first report showing a large vegetation on an elephant trunk using xenopericardial roll graft that almost totally occludes lumen during late postoperative period.See Commentaries pages 50 and 52.

The increasing use of total arch replacement and frozen elephant trunk (FET) is expected to lead an increase in the prevalence graft infections requiring involving FET, which generally a more invasive procedure than initial surgery. Herein, we describe novel method for FET removal using polyvinyl tube as storage device. completed same median sternotomy approach We report on outcomes six patients. Our simple perform safe caused no injury aorta our case series.
Abstract Background Creating a box lesion in the posterior wall of left atrium from epicardial side beating heart remains challenge. Although transmural can be created by applying radiofrequency (RF) energy at clampable sites, it is still difficult to create unclampable sites because inner blood flow free weakens thermal effect on outside. Our aim was apply newly developed infrared coagulator linear lesions thoracoscopically treat atrial fibrillation (AF). Case presentation A 71-year-old...
Immunoglobulin G4 (IgG4)-related disease is a systemic chronic inflammatory caused by infiltration of IgG4-positive plasma cells into the organs. IgG4-related arterial relatively rare not only in aorta but also small to medium-sized arteries. If vasculitis suspected on basis preoperative medical history and radiologic serologic examination findings, definitive diagnosis can be obtained open repair pathologic determine prognosis need for additional treatment. Here, we report successful...
To reduce the risk of stroke during open surgery for treatment descending thoracic or thoracoabdominal aortic diseases, we attempted to insert a proximal elephant trunk stabilize atherosclerosis at site anastomosis. Although patients had dense atherosclerotic lesions, they recovered well without neurologic complications. This technique is simple and may be effective preventing when replacing aorta through left thoracotomy.
Considerable amount of works has been reported on the study cerebral circulation, but not so many reports are available subject stem circulation .The authers performed experimental studies hemodynamics Galen's vein dogs with acute closed head injury, and results in this paper.
