A Clinical Association between an Increasing Renal Resistive Index and the Atherosclerotic Burden in Patients with a Preserved Renal Function.

Objective A positive correlation is observed between the progression of renal impairment and the increasing risk of cardiovascular disease. Our aim was to examine the relationship between the renal resistive index (RRI) assessed by duplex sonography and the extent of atherosclerosis in patients without renal impairment undergoing vascular imaging studies. Methods The RRI was evaluated pre-procedurally among 106 outpatients with an estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.

Endovascular Treatment for Kommerell's Diverticulum with a Right-Sided Aortic Arch.

We report a rare case of type A dissection involving a right-sided aortic arch with an aberrant left subclavian artery originating from Kommerell's diverticulum in a 76-year-old woman. Endovascular treatment for Kommerell's diverticulum including intimal tear of the dissection was performed. At the 5-year follow-up, the patient was doing well, with no endoleak or dilatation of the Kommerell's diverticulum.

[A Case of Aortoesophageal Fistula Rupture Due to Descending Thoracic Aortic Dissection with Recurrent Colon Cancer during Chemotherapy Containing Bevacizumab].

We report a case of aortoesophageal fistula rupture during the course of chemotherapy following colon cancer resection. The patient was a 77-year-old woman. Following recurrence of cancer of the sigmoid colon, the patient received a course of XELOX plus bevacizumab(Bmab)to treat peritoneal dissemination and lung metastases.

A Case of an Aortic Abscess around the Elephant Trunk.

A 52-year-old male patient with a history of total arch replacement using the elephant trunk technique for acute aortic dissection 4 years before visited our hospital with the chief complaint of persistent fever. Chest computed tomography (CT) suggested prosthetic vascular graft infection, which was treated surgically after chemotherapy. The first surgery consisted of debridement of an abscess around the vascular graft and in the aorta around the elephant trunk, and thoracic descending aorta replacement and vacuum-assisted closure (VAC) in view of the risk of bleeding from the peripheral region of the elephant trunk.

[Surgical Repair of Coarctation of the Aorta in an Adult;Report of a Case].

We present a case of 30-year-old man with successful bypass grafting for coarctation of the aorta. Hypertension was identified during a health examination. Blood pressure difference between the upper and lower limbs was about 60 mmHg.

Nasal methicillin-resistant S. aureus is a major risk for mediastinitis in pediatric cardiac surgery.

Background: Mediastinitis caused by methicillin-resistant Staphylococcus aureus (MRSA) is a serious complication after pediatric cardiac surgery. An outbreak of surgical site infections (SSIs) provided the motivation to implement SSI prevention measures in our institution.

Methods: Subjects comprised 174 pediatric patients who underwent open-heart surgery after undergoing preoperative nasal culture screening.

Morphological Evaluation of Proximal Anastomosis by PAS-Port(®) System in Patients with Long-Term Patent Grafts.

Purpose: We examined grafts employing for morphological analysis of early and long-term results on proximal anastomosis with the PAS-Port(®).

Methods: One hundred and four patients treated by OPCAB with PAS-Port(®) were performed postoperative MDCT. Morphological evaluation of the proximal anastomotic region was classified into three groups (A; graft was anastomosed almost perpendicularly to the aortic wall, B; graft was same type A, but subsequently curved to form an acute angle with the aortic wall, C; graft take off acute angle with the aortic wall) evaluated on planar and sagittal sections.

Interrupted aortic arch with massive saccular collateral aneurysm in an adult.

A 49-year-old man was diagnosed with an interrupted aortic arch (IAA), a massive saccular thoracic collateral aneurysm, ischemic renal insufficiency, and multiple abdominal collateral aneurysms. A bypass from the left subclavian artery to the descending aorta and thoracic collateral aneurysmectomy proceeded simultaneously through a posterolateral thoracotomy. The pressure gradient between upper and lower extremities disappeared and renal function was normalized.

Endovascular abdominal aortic aneurysm repair in patients with renal transplants: reports of two cases.

The artery and vein of the transplanted kidney are generally anastomosed to the external iliac artery and vein, respectively. Therefore, in open abdominal artery aneurysm (AAA) repair in renal transplant patients, kidney ischemia due to a proximal aortic clamp is a serious problem. We successfully performed endovascular aneurysm repair (EVAR) of AAA without aortic clamping in two renal transplant recipient cases.

Replacement of dynamic cultured biograft improves damaged heart function-comparative study of static cultured biografts-.

Purpose: To determine whether a dynamic cultured biograft can positively affect the function of the damaged heart.

Methods: We ligated the coronary artery (LAD) of rats to generate a model of myocardial infarction (MI) and then implanted them with the following grafts comprising vascular smooth muscle cells (VSMCs) derived from the rat aorta and seeded onto biodegradable patches (patch replacement therapy; (PRTx)): control without PRTx, PRTx without seeded cells, PRTx with static cultured VSMCs, PRTx with dynamic cultured VSMCs and sham-operated. Cultured VSMCs were labeled with PKH26 for identification after implantation, and the centre of the MI site was excised and replaced with an implanted biograft.

Bidirectional Glenn procedure for an infected modified Blalock-Taussig shunt.

A 1-month-old girl underwent right modified Blalock-Taussig shunt (mBTS) for pulmonary atresia with hypoplastic right ventricle. Five months after palliation, she suffered from sepsis and progressive desaturation following otitis media. Computed tomography and angiography revealed a pseudoaneurysm surrounding the mBTS graft.

Fontan conversion with novel direct ablation after childbirth: report of a case.

A 38-year-old woman underwent atriopulmonary Fontan surgery at age 18 years and subsequently successfully delivered a girl by cesarean section at age 34. Her condition later deteriorated due to atrial tachyarrhythmia and progressed to New York Heart Association (NYHA) class IV heart failure. Her treatment, at age 36, comprised total cavopulmonary connection conversion, direct right atrial ablation with bipolar radiofrequency devices, the creation of an atrial septal defect, and placement of a dual-chamber permanent pacemaker.

Stent graft implantation combined with coil embolization and external-internal iliac artery bypass surgery: report of a case.

A 73-year-old male patient was found to have an abdominal aortic aneurysm complicated with bilateral common iliac artery aneurysms. He also had hepatitis C, chronic liver cirrhosis (Child-Pugh class B), a rupture of esophageal varices, hepatocellular carcinoma, and intractable ascites. The functions of other systemic organs were also impaired.

Redo CABG for ACS via the left thoracotomy using the PAS-port system to the descending thoracic aorta: a case report.

A 74-year-old female patient with left main trunk (LMT) and triple vessel disease underwent coronary artery bypass graft (CABG) surgery. The patient began to experience exertional dyspnea. A coronary artery angiogram confirmed a severe stenosis in the proximal side of the saphenous vein graft (SVG).

[Surgical repair of a total-defect aortopulmonary window in a neonate].

Aortopulmonary window (APW) is a rare congenital heart defect that requires urgent repair, as it can lead to rapid development of pulmonary hypertension. A 6-day-old boy with a total-defect APW was transferred to our hospital and underwent definitive repair on the 15th day after birth. The ascending aorta and pulmonary trunk were divided to create a larger tissue margin on the aortic side for the next seam.
