A Case of Transapical Thoracic Endovascular Repair for Thoracic Aortic Aneurysm with a Complicated Access Route.

Thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysms (TAAs) is an alternative treatment option for high-risk patients. While conventionally performed via a transfemoral approach, it is sometimes difficult due to poor access routes. We report the case of a 90-year-old man who was incidentally diagnosed with a descending TAA while undergoing computed tomography for esophageal cancer.

Pulmonary artery reconstruction using a pulmonary vein conduit in case having an imbalanced dissection length during double-sleeve lobectomy.

Background: Among the types of lung resection procedures, pneumonectomy carries the highest risk for mortality. In recent years, bronchovascular double-sleeve lobectomy has been performed for centrally located non-small cell lung cancer involving both the bronchus and the pulmonary artery (PA) in order to avoid pneumonectomy. The use of an autologous pulmonary vein (PV) conduit for PA reconstruction during lung-sparing resections had first been reported in 2009.

Intravenous landiolol for the prevention of atrial fibrillation after aortic root, ascending aorta, and aortic arch surgery: A propensity score-matched analysis.

Objective: Postoperative atrial fibrillation (POAF) after cardiac surgery is associated with increased mortality. The efficacy of landiolol hydrochloride for POAF prevention after coronary artery bypass grafting procedure and valve surgery has been reported. However, little evidence is available on its role in POAF prevention after aortic root, ascending aorta, and aortic arch surgery.

Precise diagnosis of acute mesenteric ischemia using indocyanine green imaging prevents small bowel resection: A case report.

Introduction: Acute mesenteric ischemia (AMI) is a rare life-threatening condition that causes intestinal necrosis. Prompt intervention is essential to mitigate high mortality. In this report, we describe a case of AMI where precise diagnosis using indocyanine green (ICG) imaging to confirm sufficient bowel perfusion and viability, helped in preventing intestinal resection.

A 35-years-old pregnant woman with Marfan's syndrome visited the emergent department. She had sudden severe back pain. She was at the 20th week of gestation.

Factors for Acute Kidney Injury Following Total Arch Replacement and Association with Temperature Management During Cardiopulmonary Bypass: A Single-center Retrospective Observational Study.

Many patients develop acute kidney injury (AKI) after vascular surgery. In this retrospective observational study, we investigated the risk factors for AKI defined using the Kidney Disease Improving Global Outcomes criteria after total arch replacement (TAR). Additionally, we investigated the influence of temperature manage-ment during cardiopulmonary bypass (CPB) on postoperative renal function by propensity score-matched anal-ysis.

[Hybrid Treatment for Thoracoabdominal Aortic Aneurysm by Combined Graft Replacement and Stent-graft].

Graft replacement for thoracoabdominal aortic aneurysm(TAAA) is still an important technique, yet it has high risks of mortality, spinal cord ischemia, and pulmonary complications. In our hospital, thoracoabdominal aneurysm repair with grafting and endovascular treatment (TARGET) method was performed in patients with severe chronic obstructive pulmonary disease( COPD), severe pulmonary adhesions after descending aortic replacement, or those considered high risk from general condition to undergo a wide range replacement. In this method, thoracoabdominal aortic replacement near the diaphragm was followed by stent graft treatment of the residual proximal or distal lesions.

[Mediastinal Bronchial Artery Aneurysm Resected together with the Descending Aorta under the Partial Extracorporeal Circulation;Report of a Case].

Bronchial artery aneurysm(BAA) is quite rare, but its rupture is often lethal. Once it is found, treatments should be aggressively considered. A 67-year-old woman was diagnosed to have a 26 mm mediastinal BAA on computed tomography (CT) which was performed for screening.

[Hybrid Treatment for Aortic Arch Aneurysm Concomitant with Right Subclavian Artery Aneurysm].

A 78-year-old man was hospitalized for aortic arch aneurysm concomitant with right subclavian artery aneurysm. Maximum diameter of each aneurysm was 65 mm and 40 mm, respectively. Both aneurysms clearly needed to be treated.

Serial Follow-Up Evaluation With Computed Tomography After Conservative Medical Treatment in Patients With Symptomatic Spontaneous Isolated Superior Mesenteric Artery Dissection.

Objective: There is no detailed information available about trend in the morphological change after conservative medical treatment in patients with symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD).

Methods: We enrolled 27 consecutive patients with symptomatic SISMAD who underwent conservative medical treatment between 2006 and 2015. The long-term prognosis, natural history, and serial follow-up computed tomography (CT) findings of risk factors of rupture such as arterial diameter and false lumen enhancement were retrospectively assessed.

Spinal cord protection during thoracoabdominal aortic replacement: spinal cord perfusion maintenance.

Objectives: Spinal cord protection during thoracoabdominal aortic surgery is challenging for surgeons. We performed thoracoabdominal replacement using a strategy for maintaining spinal cord perfusion pressure. Here, we report our experience with this procedure and the surgical outcomes.

Innominate artery cannulation for arterial perfusion during aortic arch surgery.

Objective: Antegrade cerebral perfusion during aortic arch surgery plays an important role in improving postoperative neurological outcomes. We report our experience using innominate artery cannulation for arterial perfusion during aortic arch surgery.

Methods: From January 2008 to December 2015, 159 patients underwent aortic arch surgery using innominate artery perfusion and were included in the study analysis (mean age, 71.

Operative results of the anterolateral thoracotomy with partial sternotomy approach for chronic-type B aortic dissection involving the aortic arch.

Objectives: There are various treatment strategies for chronic-type B aortic dissection involving the aortic arch. Our aim was to review our surgical experience in the anterolateral thoracotomy with the partial sternotomy approach for chronic-type B aortic dissection involving the aortic arch.

Methods: From January 2000 to October 2015, 39 patients underwent the single-stage open surgery for chronic-type B aortic dissection involving the aortic arch using the anterolateral thoracotomy with partial sternotomy approach.

[Closure of Ascending Aortic Entry by Debranching Endovascular Management in an Elderly Patient with Acute Stanford Type A Dissection].

An 85-year-old woman was hospitalized by emergency for an acute Stanford type A aortic dissection. Computed tomography showed a primary entry on the ascending aorta and pericardial effusion. Although her hemodynamics was unstable due to cardiac shock, her family wished no open surgery considering her age and frailty.

Outcomes of Anterolateral Thoracotomy With or Without Partial Sternotomy for Kommerell Diverticulum.

Background: Kommerell diverticulum is a rare aortic arch anomaly. The indications for operative intervention and surgical strategy are still controversial. The standard surgical procedure at our institution is total aortic arch plus descending aortic replacement using anterolateral thoracotomy with partial sternotomy.

Baseline disease is a more important predictor of intestinal necrosis than CT findings in patients with acute mesenteric ischemia.

Objective: Acute mesenteric ischemia (AMI) is a potentially fatal vascular emergency, and several computed tomographic (CT) findings have been introduced to determine the presence of intestinal ischemia or necrosis, although the most useful finding is unknown.

Methods: We retrospectively analyzed data of 43 consecutive patients with AMI who were treated during the period from 2006 to 2015. Study patients included both superior mesenteric artery dissection (n = 29) and thrombosis (SMAT, n = 14).

Outlet strut fracture and leaflet escape of Bjork-Shiley convexo-concave valve.

Prosthetic valve fracture is a serious complication and may arise in patient post-valve replacement. We experienced an outlet strut fracture and leaflet escape of a Bjork-Shiley convexo-concave valve. We performed an emergency redo mitral valve replacement and successfully retrieved the fractured strut and escaped leaflet from superficial femoral artery and the abdominal aorta.

Cardiac resynchronization therapy for ischemic myopathy.

We performed coronary artery grafting, mitral valve plasty, and tricuspid plasty in a 75-year-old man who had double-vessel coronary disease and moderate mitral and tricuspid insufficiency. Preoperative transthoracic echocardiography revealed an ejection fraction of 34% and dyssynchronous wall motion of the septum and free wall. We placed pacing leads on the right ventricular outlet and posterior left ventricular wall for cardiac resynchronization therapy.

Impact of Noninvasive Conservative Medical Treatment for Symptomatic Isolated Celiac Artery Dissection.

Background: There is no definite consensus regarding the management of symptomatic isolated celiac artery dissection (ICAD), and the effect of conservative medical treatment has never been evaluated.

Methods and results: We enrolled 13 consecutive symptomatic ICAD patients without signs of arterial rupture between 2006 and 2015. All patients received noninvasive conservative medical treatment.

[Thoracic endovascular aneurysm repair combined with debranching and chimney methods in a high risk patient; report of a case].

We report a case of a 77-year-old man with a thoracic aortic aneurysm, combined with chronic myelomonocytic leukemia, polymyalgia rheumatica, and atial fibrillation. Open surgery was considered as high risk because he was severely ill. Instead, partial debranching and stent graft( TEVAR) were performed by chimney method.

Aortic aneurysm and craniosynostosis in a family with Cantu syndrome.

Cantu syndrome is an autosomal dominant overgrowth syndrome associated with facial dysmorphism, congenital hypertrichosis, and cardiomegaly. Some affected individuals show bone undermodeling of variable severity. Recent investigations revealed that the disorder is caused by a mutation in ABCC9, encoding a regulatory SUR2 subunit of an ATP-sensitive potassium channel mainly expressed in cardiac and skeletal muscle as well as vascular smooth muscle.

Peripheral pseudoaneurysm in active Behçet's disease: surgical and perioperative therapeutic strategies.

Since aneurysms in patients with Behçet's disease are often pseudoaneurysmal and adjacent arteries are highly inflammatory, there is not only a risk of rupture but also a high incidence of late surgical complications at anastomotic sites. Furthermore, there is no consensus on perioperative medical therapeutic strategy in patients with active vasculo-Behçet's disease who require surgery. Herein, we present two cases of active Behçet's disease, a 51-year-old male with rupture of the left internal iliac artery who required emergent operation and a 31-year-old male with a rapidly developed pseudoaneurysm in the right superficial femoral artery.

Coronary artery bypass grafting with left inferior epigastric artery as collateral.

We report a case of co-existent coronary and peripheral vascular disease with collaterals to the lower extremities in a 72-year-old female. The patient had triple-vessel coronary artery disease, an occlusion of the bilateral iliac arteries, and the left internal mammary-inferior epigastric artery collateral pathway was a major route to the lower extremities. Coronary artery bypass grafting and right axillo-bifemoral bypass were performed.

Left ventricle to pulmonary arterial fistula due to Behçet's disease.

Surgical treatment of aortic regurgitation due to Behçet's disease is difficult. A 57-year-old male with Behçet's disease underwent aortic valve replacement with a mechanical valve for aortic regurgitation in 1995. Due to prosthetic valve detachment, 5 months thereafter he underwent a Bentall type operation with a composite graft.
