We reviewed the results of endovascular aneurysm repair in patients from Japanese Committee for Stentgraft Management registry to determine significance persistent type II endoleak (p-T2EL) and risk late adverse events, including sac enlargement.The prospectively captured medical records 17 099 <75 years age who underwent abdominal aortic 2006 2015 were reviewed. Patients divided into 2 groups (with or without p-T2EL) compared examine correlation between p-T2EL occurrence enlargement after...
Owing to the time-sensitive nature of myocardial ischemia, challenging clinical scenarios should be considered in patients with type A acute aortic dissection (AAAD) complicated by coronary malperfusion. In settings, diagnosis and reperfusion strategies for malperfusion often depend on institutional resources. This study evaluated early surgical outcomes such patients, focusing transportation management. We retrospectively reviewed 70 who underwent emergency surgery AAAD malperfusion,...
Treatment options for patients with chronic thromboembolic hypertension (CTEPH) have increased over the past decade. However, it is unknown whether outcomes of CTEPH changed as well. This retrospective study analysed data 834 CTEPH, categorised into early (April 1980-December 1999), middle (January 2000-September 2010), and current (October 2010-December 2023) eras. The primary endpoint was all-cause mortality. Multivariable Cox proportional hazards models were used to assess changes in...
Objectives: This study aimed to investigate the actual detection process and diagnostic methods for asymptomatic abdominal aortic aneurysm (AAA) in a multicenter setting, plan an effective screening strategy AAA. Methods: The subjects of this were collected retrospective manner at 7 facilities. A total 1894 patients with AAA, including iliac artery aneurysms, who considered confirmed initial diagnosis from January 2018 December 2022, reviewed. Results: 1666 diagnosed AAA included [83.9%...
An entry located at aortic arch in acute type A dissection (AAAD) is uncommon. It remains controversial whether or not aggressive primary resection should be routinely performed such patients. We have adopted an strategy of site resection, including total replacement (TAR) patients with tears. The purpose this study was to investigate the efficacy our surgical management approach, using resection.Between January 2000 and December 2014, we retrospectively reviewed records 334 AAAD who...
Abstract OBJECTIVES In patients with acute type A aortic dissection, the use of frozen elephant trunk (FET) procedure total arch replacement (TAR) has been indicated for emergency operations to obtain thrombosis distal false lumen (FL). However, data comparing FET and classical (CET) procedures, including incidences mortality, morbidity, spinal cord injury remodelling, have not yet reported. The goal this study was compare early outcomes TAR CET procedures. METHODS past 7 years medical...
We investigated the prevalence, risk factors, and optimal timing of treatment for advanced periodontitis in patients undergoing elective heart valve surgery. Dental examinations were given to 209 (aged 65 ± 10 years) scheduled Patients with no or mild assigned as controls (n = 105). underwent tooth extraction curettage 104), 68 whom within two weeks (short wait) 36 longer than weeks, before The three groups (control, short, long similar age, gender, diseased valve, type surgery received....
Background— To address the lack of information about size ruptures associated with chronic dissection in descending and thoracoabdominal aorta, we evaluated natural history this pathology. Methods Results— We analyzed data from 571 patients (mean age, 69.4±11.6 years) unrepaired aortic or aorta a maximal diameter ≥3.5 cm 2007 to 2014. This was cross-sectional study. Data on timing computed tomographic scan were as follows: for ruptured cases: at time rupture; nonruptured initial diameter....
Arch repair using the frozen elephant trunk (FET) technique has been utilized to treat Type A acute aortic dissection. In contrast, long-term outcomes of non-FET focus on thrombosed false lumen (FL), and distal reoperation rates remain unclear. The goal our study was investigate efficacy as benchmark.We reviewed 518 patients with dissection in last 20 years. Among them, 139 hospital survivors (61 ± 12 years) who had undergone total arch replacement were enrolled. 86% (120/139) a patent FL at...
Spiral incision of the thoracic wall towards tip a scapula and approach through sixth intercostal space has been standard method for replacement thoracoabdominal descending aortic aneurysms. However, exposure proximal lesion aorta with spiral is not always sufficient patients extending into arch. Patients Marfan syndrome tend to have flat chest, using left thoracotomy generally causes difficulty operate on arch.Since May 2012, 47 (mean age 51.2 ± 16.1, range 9-79, 33 males) received novel...
We retrospectively reviewed the surgical results of thoraco-abdominal aortic repair using moderate-to-deep hypothermia combined with targeted reconstruction Adamkiewicz artery (AKA). Between 2006 and 2014, 100 patients underwent aneurysm hypothermia. Their mean age was 58 ± 15 years 76 (76%) were men. pathologies included acute dissection (5), chronic (74), degeneration (20) infection (1). Thirty-four had connective tissue disorders 5 emergency operations. The degrees Crawford extent I for...
The management of acute type A aortic dissection with malperfusion syndrome remains challenging. To evaluate preoperative condition, symptoms might be subjective and objective evaluation cerebral artery has not yet been established. For quantitative evaluation, this study focused on brain computed tomography perfusion (CTP), which recommended by several guidelines ischaemic stroke.In the last 2 years, 147 patients hospitalized due to were retrospectively reviewed. Among 23 (16%)...
We investigated whether prophylactic preoperative cerebrospinal fluid drainage (CSFD) was effective in preventing spinal cord ischemia (SCI) during thoracic endovascular aortic repair of degenerative descending aneurysms, excluding dissecting aneurysms.We retrospectively reviewed the medical records patients who underwent involving proximal landing zones 3 and 4 between 2009 2020.Eighty-nine with preemptive CSFD [68 men; median (range) age, 76.0 (71.0-81.0) years] 115 without [89 77.0...
OBJECTIVES: This study aims to determine whether warfarin therapy influences the occurrence of endoleaks or aneurysm sac enlargement after endovascular aortic repair (EVAR). METHODS: A total 367 patients who underwent EVAR for abdominal between 2007 and 2013 were recruited this study. Satisfactory follow-up data including completed computed tomography scan more than 2 years available 209 patients, mean time was 37 ± 12 months. Twenty-nine (16%) on (warfarin group), whereas 180 (84%) not...
The aim of this retrospective study was to investigate the effect chronic kidney disease (CKD) on outcomes after coronary artery bypass grafting (CABG), and determine whether preoperative estimated glomerular filtration rate (eGFR) can be a predictor long-term CABG.486 Japanese patients who underwent isolated CABG between December 2000 August 2010 were evaluated. Preoperative eGFR by equation according guidelines from Society Nephrology. We defined CKD as less than 60 ml/min/1.73 m(2). 203...
Takayasu arteritis (TAK) is classified as a large vessel vasculitis and often causes vascular stenosis, occlusion, aneurysm formation. Although the principal treatment for TAK involves suppressing inflammation with glucocorticoids, emergence of biological disease-modifying antirheumatic drugs has considerably changed landscape in recent years. Several drugs, such tocilizumab (TCZ), have shown promising effects on clinical studies. Cardiologists cardiovascular surgeons encounter patients...
