[A Case of Left Renal Cell Carcinoma with Renal Arteriovenous Fistula and Multiple Vascular Malformation Undergoing Nephrectomy].

A 69-year-old woman was referred to our hospital for the treatment of a left renal tumor found by computed tomography (CT) during examination for microscopic hematuria. Contrast-enhanced CT showed a 5 cm tumor in the inferior pole of the left kidney. Left renal cell carcinoma (RCC) (cT1bN0M0) was suspected.

Embolization of Deep Femoral Artery Aneurysm with a Ligated Proximal Artery Using the Direct Percutaneous Puncture Technique.

We report a case of a deep femoral artery aneurysm with a ligated proximal artery that was successfully managed with endovascular therapy. An 84-year-old male was referred to our institute with a history of surgical resection of a left ruptured deep femoral artery aneurysm wherein another aneurysm was found on the peripheral side. Proximal artery ligation of the peripheral lesion was performed.

Additional frozen elephant trunk as a bailout for a misdeployed frozen elephant trunk in the false lumen in a patient with acute aortic dissection.

Using a frozen elephant trunk (FET) in patients with acute aortic dissection is an effective method to induce aortic remodelling after surgery. A 40-year-old man with Stanford type A acute aortic dissection underwent emergency total arch replacement with FET. The FET was inserted into the descending aorta under direct vision.

Successful Aortic Banding for Type IA Endoleak Due to Neck Dilatation after Endovascular Abdominal Aortic Aneurysm Repair: Case Report.

A 69-year-old man with a type IA endoleak that developed approximately 21 months after endovascular abdominal aortic aneurysm repair (EVAR) of a 46 mm diameter aneurysm was referred to our department. He had impaired renal function, Parkinson's disease, and previous cerebral infarction. Computed tomography angiography showed a type IA endoleak with neck dilatation and that the aneurysm had grown to 60 mm in diameter.

Pulmonary Stenosis Caused by Ductus Arteriosus Aneurysm: A Case Report.

A 76-year-old woman with a 2-week history of dyspnea on exertion was admitted to our hospital. A computed tomography scan showed a 70-mm diameter aortic arch aneurysm containing a large thrombus that was compressing the pulmonary artery. Echocardiography showed severe pulmonary stenosis and no shunt flow.

[Mitral Valve Replacement under Ventricular Fibrillation through Right Thoracotomy for Severe Mitral Regurgitation with Low Left Ventricular Function after Coronary Artery Bypass Grafting；Report of a Case].

A 64-year-old woman had undergone coronary artery bypass grafting (CABG:left internal thoracic artery-left anterior descending artery, right internal thoracic artery-1st diagonal branch, saphenous vein graft-posterior descending artery) 5 years before. However, she was referred to us due to worsening of dyspnea. Severe mitral regurgitation with tethering and tricuspid regurgitation were observed by echocardiography, and low left ventricular function with ejection fraction of 32.
