[Surgical Resection Papillary Fibroelastoma Arising from Left Atrium:Report of a Case].

Kyobu Geka 2021 Oct;74(11):967-971

Department of Cardiovascular Surgery, Jichi Medical University Saitama Medical Center, Saitama, Japan.

A 75-year-old man was admitted for cerebral infarction. Magnetic resonance imaging revealed parietal lobe cerebral infarction. Transesophageal echo and contrast-enhanced computed tomography indicated mobile and speckled mass arising from left atrium. He was diagnosed with cardiogenic cerebral embolism. Under cardiopulmonary bypass, resection of the mass including endocardium tissue was per formed. The resected specimen showed multiple small fronds resembling a sea anemone. Microscopic examination showed multiple branching fronds of paucicellular and avascular fibroelastic tissue lined by a single layer of endocardium. Pathological diagnosis was papillary fibroelastoma. Three years passed without recurrence.

[Subacute Pseudoaneurysm Formation after Sutureless Repair for Postinfarction Left Ventricular Rupture:Report of a Case].

Kyobu Geka 2021 Sep;74(9):697-700

Department of Cardiovascular Surgery, Jichi Medical University Saitama Medical Center, Saitama, Japan.

A 71-year-old woman was admitted for cardiac tamponade due to left ventricular free wall rupture after acute myocardial infarction. Sutureless repair was performed for bleeding from the inferior wall. Fifteen days later, computed tomography demonstrated enlargement of a left ventricular pseudoaneurysm. Patch closure using a vascular prosthesis was performed through left thoracotomy. No recurrence of the left ventricular aneurysm has been observed since.

[Revascularization of the Right Common Carotid Artery Prior to Central Repair for Stanford Type A Acute Aortic Dissection with Brain Malperfusion:Report of a Case].

Kyobu Geka 2021 Jul;74(7):558-560

Department of Cardiovascular Surgery, Yokosuka Municipal Uwamachi Hospital, Yokosuka, Japan.

A 67-year-old woman had sudden loss of consciousness and chest and back pain. She was transported by ambulance about two hours later. Computed tomography (CT) showed dissection of the aorta, the brachiocephalic artery and the right common carotid artery (RCCA). RCCA was completely obstructed. Emergency surgery was conducted one hour later. RCCA's blood flow was reestablished prior to hemi-arch replacement. Postoperative CT revealed diminishment of the false lumen and recovery of the blood flow of RCCA, and she was discharged on foot without any complications.

[Patch Repair by Anterolateral Thoracotomy with Partial Sternotomy for Saccular Aortic Arch Aneurysm with Severe Thoracic Deformity:Report of a Case].

Kyobu Geka 2021 Feb;74(2):147-151

Department of Cardiovascular Surgery, Yokosuka Municipal Uwamachi Hospital, Yokosuka, Japan.

An 87-year-old male was referred to our hospital for surgery of saccular aortic arch aneurysm. As he had a history of thoracoplasty on his left side due to pulmonary tuberculosis, his aortic arch adhered to the apex of the left thorax. Total arch replacement(TAR) via median sternotomy was considered difficult, and anterolateral thoracotomy with partial sternotomy (ALPS) was performed. During surgery, we considered TAR difficult even with ALPS approach. Taking account of his age, aneurysmectomy and patch repair were chosen instead of TAR to shorten operation time. Although he suffered from diffuse cerebral infarction, he was discharged without neurological deficit at 39 days after operation.

[Pseudoaneurysm with Infective Endocarditis Ten Years After the Resection of Pseudoaneurysm Complicated with Myocardial Infarction;Report of a Case].

Kyobu Geka 2019 Oct;72(11):923-927

Department of Cardiovascular Surgery, Yokosuka Municipal Uwamachi Hospital, Yokosuka, Japan.

A 76-year-old female was referred to our hospital for fever and chillness. She was diagnosed with pneumonia and sepsis, and methicillin-resistant Staphylococcus aureus (MRSA)was detected by the sputum culture. Echocardiography showed mobile vegetation and left ventricular pseudoaneurysm at the apex. As she had a history of ventricular pseudoaneurysmectomy 10 years before, we considered the patient had developed infective endocarditis at the surgical site. Surgical treatment was needed because of the rapidly growing pseudoaneurysm despite the use of antibacterial agents. She successfully underwent resection of the pseudoaneurysm and MRSA was also detected in the culture of the previous vascular graft patch. Antibacterial agents were administrated for 6 weeks, and she was discharged at 53 days after operation.

Off-pump coronary artery bypass grafting via left anterior thoracotomy from the 4th costal space in a patient with total laryngectomy and a permanent tracheostoma.

Gen Thorac Cardiovasc Surg 2020 Jun 20;68(6):633-636. Epub 2019 May 20.

Department of Cardiovascular Surgery, Yokosuka Uwamachi Hospital, 2-36 Uwamachi, Yokosuka, Kanagawa, 238-8567, Japan.

Median sternotomy is the standard approach for coronary artery bypass grafting. Herein, we performed off-pump coronary artery bypass grafting via left anterior thoracotomy from the 4th costal space in an unstable angina pectoris patient with total laryngectomy and a permanent tracheostoma. In this patient, median sternotomy had high risks of surgical-site infection and tracheal injury. To avoid these risks, we selected left anterior thoracotomy. Initially, it was difficult to expose the ascending aorta and postdescending branch. With extension of the skin incision to the median area and division of the 5th and 6th ribs and costal arch, we could expose the anastomotic sites, including the ascending aorta and postdescending branch, without median sternotomy conversion. We performed multiple coronary artery bypass graft procedures safely. This approach might be an additional surgical option in patients with total laryngectomy and a permanent tracheostoma.

[Combined Thoraco-abdominal Aortic Aneurysm Repair and Coronary Artery Bypass Grafting through a Left Thoracotomy].

Kyobu Geka 2018 Aug;71(8):588-592

Department of Cardiovascular Surgery, Yokosuka General Hospital Uwamachi, Yokosuka, Japan.

Approximately 40% of the patients with aortic aneurysm have coronary artery disease(CAD), which is an important factor contributing to early mortality associated with aneurysm surgery. Combined coronary artery bypass grafting (CABG)and aortic aneurysm repair of the ascending aorta to the aortic arch is often performed through a median sternotomy due to a good surgical exposure. However, treatment strategy of thoraco-abdominal aortic aneurysm(TAAA) combined with CAD is often controversial. We report a successful case of a 69-year-old man who underwent TAAA repair and CABG through a left thoracotomy. Left thoracotomy via the 5th intercostal space with para-rectal incision provides a good surgical exposure of the thoraco-abdominal aorta and the left anterior descending artery(LAD). LAD was revascularized with a saphenous vein graft which was anastomosed to the descending aorta, followed by TAAA repair. The postoperative course was uneventful and the patient was discharged on 13th postoperative day without any complications.
