Aortoesophageal fistula 19 years after radiotherapy for oesophageal cancer: a case report.

Background: Aortoesophageal fistula (AEF) is a life-threatening disease that causes massive bleeding, sepsis, and ultimately death. Therefore, emergency treatments are required. Recently, cases of AEF treated with thoracic endovascular aortic repair (TEVAR) have been reported.

Midterm Morphological Change of Kommerell's Diverticulum after Hybrid Thoracic Endovascular Aortic Repair.

Background: Kommerell's diverticulum (KD) is associated with a high incidence of right-sided aortic arch (RAA). Hybrid thoracic endovascular aortic repair (TEVAR) is an effective and less invasive alternative to open repair. However, the long-term results regarding KD diameter regression or symptom improvement remain inadequately described.

Mycotic superior mesenteric artery aneurysm with impending rupture due to infective endocarditis.

A 49-year-old woman with tachycardia was referred to our institution. Transthoracic echocardiography revealed severe mitral regurgitation, and surgery was planned. While awaiting surgery, she developed a fever.

A surgical resection case of myxoma arising from the posterior wall of the left atrium complicated with complete atrioventricular block.

An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near the atrioventricular node.

Successful "PETTICOAT" procedure assisted by aortic angioscopy for complicated type B aortic dissection: Case report.

Introduction: Thoracic endovascular aortic repair (TEVAR) is a useful treatment for acute type B aortic dissection (TBAD). A PETTICOAT (Provisional ExTension to Induce COmplete ATtachment) procedure can be an alternative surgical option for a patent false lumen. Non-obstructive aortic angioscopy is an attractive modality that can visualize the aortic intima for things such as entry or re-entry tears that are difficult to detect with computed tomography (CT).

Successful surgery for secondary aortoduodenal fistula based on F-fluorodeoxyglucose positron emission tomography/computed tomography findings.

Secondary aortoduodenal fistula (sADF) is a critical late complication of abdominal aortic repair, requiring complete excision of the infected prosthesis. However, this is a highly invasive procedure for the elderly. We describe a case of sADF repair in a 76-year-old woman.

Total arch and descending thoracic aortic replacement for massive hemoptysis requiring CPR caused by intrapulmonary penetration of chronic dissecting aortic aneurysm: a case report.

Background: Intrapulmonary penetration of the thoracic aorta is a rare, life-threatening complication of a chronic dissecting aortic aneurysm. It causes massive hemoptysis requiring prompt intervention to prevent fatal airway bleeding. A surgical approach that enables diverse surgical maneuvers and intraoperative organ protection is crucial.

Successful concomitant minimally invasive surgery for aortic valve stenosis and right lung cancer via right mini-thoracotomy : A case report.

Background: The case of aortic valve stenosis complicated with lung cancer have compelled cardiovascular surgeons to make challenging. We report the first successful short-term outcomes of one-stage minimally invasive aortic valve replacement and video-assisted thoracoscopic surgery lobectomy through right mini-thoracotomy in a patient with synchronous bicuspid severe aortic valve stenosis which was unsuitable for transcatheter aortic valve implantation and right lung cancer.

Case Presentation: A 76-year-old man with severe aortic valve stenosis was diagnosed with lung cancer of the right upper lobe with stage IA2.

A Case of CABG in a Patient with High Risk of Coronary Obstruction during TAV-in-TAV.

A 94-year-old man who underwent transcatheter aortic valve (TAV) replacement 6 years ago was admitted because of exertional dyspnea. Transthoracic echocardiography revealed severe aortic regurgitation owing to TAV dysfunction. The patient was considered to have a high risk of occlusion of the sinus of Valsalva during TAV-in-TAV.

Successful redo aortic valve replacement using Perceval valve in a patient with prosthetic valve endocarditis complicated by acute cerebral infarction.

Introduction: and importance: For treatment of prosthetic valve endocarditis (PVE), redo-aortic valve replacement (AVR) is usually required. However, the recurrence of PVE continues to be a serious problem that needs a solution.

Case Presentation: An 83-year-old woman who had undergone AVR for aortic infective endocarditis 12 years ago was diagnosed with PVE complicated with acute cerebral infarction.

Successful hybrid TEVAR for distal anastomotic pseudoaneurysm and coarctation following previous palliative left subclavian artery to descending aorta bypass: A case report.

Introduction: Anastomotic pseudoaneurysm is one of the most common but catastrophic complications in coarctation of the aorta (CoA); this is equally true even if the initial surgery is not directly related to the coarctation. Redo open heart surgery is usually required for the pseudoaneurysm; however, redo surgery remains challenging with high morbidity and mortality rates.

Presentation Of Case: A 38-year-old woman with CoA, who had undergone left subclavian artery (LSCA) to descending aorta bypass 21 years prior, was referred to us for the treatment of distal anastomotic pseudoaneurysm.

[Tips for Use of Chordal Guide System for Easy Adjustment of Appropriate Artificial Chordae Length in Patients Undergoing Minimally Invasive Mitral Valve Repair].

Objectives: In patients who require minimally invasive mitral valve repair (MICS-mitral), it is difficult to determine the appropriate length of artificial chordae, position, and number of artificial chordae. The Memo 3D Rechord, a complete prosthetic ring associated with a temporary chordal guide system comprised of yellow loops that function as a reference guide for automatically determining the height of neo-chordae. We sought to evaluate our tips for use of this system.

A case of severe headache attributed to vertebral artery dissection.

Background: Vertebral artery dissection (VAD) sometimes has no specific symptoms and is difficult to differentiate from other forms of headache.

Case Presentation: A woman in her thirties had a severe, throbbing left-sided headache. A migraine without aura was suspected and zolmitriptan was administered, which alleviated the symptoms.

Effects of an intrathecal TRPV1 antagonist, SB366791, on morphine-induced itch, body temperature, and antinociception in mice.

Purpose: Transient receptor potential vanilloid 1 (TRPV1) not only is activated by multiple stimuli but also is involved with histamine-induced itch. The effects of TRPV1 on morphine-induced itch are unknown. We examined the effects of intrathecal administration of TRPV1 antagonist on morphine-induced itch, body temperature, and antinociception for mice.

[Recipient of living kidney transplantation during which heparin-induced thrombocytopenia (HIT) was suspected: a case report].

A 67-year-old woman with a diabetic renal failure was scheduled for a living kidney transplantation. Heparin was first used during hemodialysis 5 days before operation. Thrombocytopenia was found immediately after induction of general anesthesia, and the diagnosis of HIT was wade based on clinical symptom and 4 T's scoring.

Differential diagnosis of breast mass image-forming lesions based on changes in depth-width ratio and internal echo intensity by hand-held probe compression.

Purpose: Regarding mass image-forming lesions, the 2005 Guidelines for Ultrasonic Diagnosis of Breast Diseases, published by the Japan Society of Ultrasonics in Medicine (JSUM), includes the evaluation of tumor compressibility, which is visually assessed by the degree of deformation caused by applying external pressure to the tumor. However, this is only a subjective estimation under real-time observation; consequently, quantitative evaluation of tumor deformation and the percentage change in internal echo intensity was attempted based on changes in the depth-width ratio and in the internal echo intensity on hand-held probe compression. We evaluated the usefulness of these measurements in the differential diagnosis of benign and malignant tumors.
