Our goal was to evaluate the combined effects of balloon pulmonary angioplasty (BPA) followed by endarterectomy (PEA) treat high-surgical-risk patients with chronic thromboembolic hypertension (CTEPH).This study included 58 CTEPH who had vascular resistance ≥1000 dyn·s/cm5, mean arterial pressure (mPAP) ≥45 mmHg or mPAP 38-44 comorbidities. Of these, 21 underwent therapy BPA PEA (BPA group) and 37 direct (non-BPA group). Preoperative postoperative results were compared between 2 groups. An...
Pulmonary endarterectomy (PEA) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH) but can result in respiratory and cardiac complications that may require extracorporeal membrane oxygenation (ECMO). We reviewed our experience with ECMO patients undergoing PEA.Between January 2012 August 2015, 35 underwent PEA CTEPH. In all, four (11%) required veno-arterial (V-A) support due to severe failure, including reperfusion edema persistent hypertension. No...
Abstract Background Aortoesophageal fistula (AEF) is a relatively rare condition that often life-threatening. Secondary AEF complication of previous surgery, which can be more critical and challenging than primary AEF. The number secondary increasing due to increase in the thoracic endovascular aortic repair (TEVAR). Although TEVAR has become successful alternative surgical strategy for aneurysms, after might other because severe adhesion between esophagus residual wall. Methods This study...
The purpose of this study was to determine the predictive ability neutrophilia, lymphocytopenia, and neutrophil-lymphocyte ratio (NLR) for overall mortality after EVAR AAA.Data on patients with AAA treated by between March 2012 December 2016 were obtained from a prospectively maintained database at Tokyo Medical University Hospital, Tokyo, Japan. NLR calculated dividing absolute neutrophil count lymphocyte count. A cut-off value total WBC count, determined according receiver operating...
We aimed to review 50 consecutive Japanese abdominal aortic aneurysm (AAA) and common iliac (CIAA) patients evaluate the 2-year outcomes, particularly endoleak sac shrinkage, of Endurant stent graft.Between June 2012 January 2014, AAA CIAA underwent EVAR with graft. Clinical outcomes overall survival, aneurysm-related secondary intervention-free survival were analyzed; endoleaks changes also evaluated.The Kaplan-Meier estimates for 85.4%, 97.7% one device-related death, 84.9%, respectively....
Some recent reports have demonstrated that preoperative Adamkiewicz artery (AKA) identification and its targeted reconstruction has provided satisfactory outcomes with respect to spinal cord protection. This paper investigates the impact of AKA on reducing incidence injury (SCI) in open repair (OR) endovascular (EVR) descending thoracic aortic (dTA) thoracoabdominal aneurysm (TAA) repair.The clinical data patients dTA TAA treated between 2011 2022 were investigated. A total 256 comprising...
Background: Localized aortic dissection on the left coronary cusp with critical malperfusion of main trunk (LMT) is rare and carries a high risk death.
Internal mammary artery (IMA) aneurysms are very rare, have a high risk of rupture, and can cause hemothorax. Here, we report the case 33-year-old man with metachronal bilateral IMA aneurysms. He had Marfan syndrome diagnosed by genetic testing. We carried out endovascular repair coil embolization. has survived without additional treatment for 7 years. Endovascular is feasible even in patient syndrome.
A retrospective analysis was performed to determine the impact of genetically diagnosed connective tissue disease (CTD) on early and late outcomes surgical treatment for aortic dissection in patients having pathology associated with cystic medial necrosis (CMN).Between 2003 2013, a total 43 (37 ± 12.8 years old, 23 men, 20 women) who had undergone surgery CMN wall underwent genetic examinations. Subsequently, there were 30 CTD (CTD group) 13 without (non-CTD group).There no or deaths (the...
To evaluate the 4-year results of Endurant stent-graft in treatment abdominal aortic aneurysm (AAA) or common iliac artery (CIAA).Between June 2012 and January 2014, 50 consecutive Japanese AAA CIAA patients were treated with at Tokyo Medical University Hospital.Estimated freedom from overall mortality, aneurysm-related secondary interventions 4 years was 61.7%, 97.9%, 78.6%, respectively. At years, maximum sac diameter decreased by >5 mm 24% patients, remained stable 52%, increased 24%. The...
Anticoagulation control in active inflammatory bowel disease (IBD) is challenging because of hypercoagulation and bleeding complications. The strategy for treating chronic thromboembolic pulmonary hypertension (CTEPH) IBD remains controversial only a few studies have reported its successful treatment (Kim Lang. Eur Respir Rev 21: 27-31, 2012, Bonderman, et al. Circulation 115: 2153-8, 2007). We describe case CTEPH with Crohn's successfully treated endarterectomy (PEA).A 49-year-old man had...
A 70-year-old man was referred to our hospital for an abnormal chest shadow. Enhanced computed tomography (CT) revealed 2-humped bronchial artery aneurysms (BAAs) associated with racemose hemangioma. The combined therapy of transcatheter embolization and thoracic endovascular aortic repair performed. Postoperative CT confirmed the complete exclusion no evidence endoleak. Our result suggests that this is a safe effective treatment BAA.
Endovascular aneurysm repair (EVAR) results in a marked reduction of intrasac pressure, which is the likely cause sac shrinkage. We evaluated change pressure during operation and its association with shrinkage one year after EVAR.This study included 113 patients undergoing EVAR using Gore C3 Excluder at our university hospital between March 2016 December 2020. A direct was measured before stent deployment. The Pressure Index (PI) defined as ratio to systemic blood pressure.Patients were...
Abstract OBJECTIVES The presence of collateral network circulation to the spinal cord, which is reflected in repair a descending thoracic aortic aneurysm (dAo) and thoraco-abdominal (TAAo), has been demonstrated clinical animal experimental data. latissimus dorsi muscle (LDM) including thoracodorsal artery might be one major sources this network. objective study was evaluate impact on cord safety left anteroaxillary thoracotomy with minimal division preservation LDM surgery for dAo TAAo....
Rare primary coronary artery pseudoaneurysms in a young patient with heterozygous FH was successfully repaired direct closure of intimal defects aneurysmorrhaphy.
Coronary malperfusion associated with aortic dissection is fatal when it occurs. Although there are some case reports of coronary involving a single artery, the involvement bilateral arteries extremely rare. The appropriate management this phenomenon remains controversial because difficulty in its accurate diagnosis and prompt treatment. We report 2 cases type A arteries.In first case, aortography revealed acute (AAD) artery angiography (CAG) showed obvious patient was transferred to...

Transesophageal echocardiography (TEE) is a necessary diagnostic tool for cardiac surgery, including intraoperative evaluation of the morphology and function each structure. On other hand, many complications caused by insertion manipulation TEE probe have been reported, such as gastrointestinal injuries hematoma, well esophageal perforation. Here, we report case in which large submucosal hematoma was found on fourth postoperative day after surgery using mitral regurgitation. The patient an...
