Efficacy of modified less invasive quick replacement using mild hypothermic arrest and partial retrograde cerebral perfusion for type A acute aortic dissection.

Objective: We previously reported a unique technique called "less invasive quick replacement (LIQR)" for treating type A acute aortic dissection with moderate hypothermic arrest (28 °C). This study examines the modified LIQR using mild hypothermic arrest (30 °C) with partial retrograde cerebral perfusion (RCP).

Methods: 187 patients were divided into 2 groups: group L consisted of 130 patients underwent LIQR without any cerebral perfusion; group M consisted of 57 patients who were treated with modified LIQR.

Cystic Adventitial Disease of the Common Femoral Artery. Case Report and Review of the Literature.

Purpose: Cystic adventitial artery disease is an uncommon non-atherosclerotic peripheral vessel disease. Furthermore cystic adventitial disease of the common femoral artery is an extremely rare entity. We report the case of a 54 year-old man complaining of intermittent claudication who was referred to our vascular service.

Emergency coronary artery bypass grafting after substernal gastric tube interposition for esophageal cancer.

A 67-year-old man who had undergone substernal gastric tube interposition due to esophageal cancer showed ST changes on electrocardiography. Diagnosis was severe stenosis of the left anterior descending branch that required emergency coronary artery bypass grafting. Preoperative computed tomography (CT) showed the feeding arteries of the gastric tube were in contact with the left internal mammary artery.

Emergency repair of acute aortic dissection in a patient with relapsing polychondritis.

Relapsing polychondritis (RP) is a rare, inflammatory, multiorgan disorder affecting cartilaginous structure and other connective tissue. Cardiovascular complications occur in 10%-52% of patients. We report a case of emergency surgery for an acute aortic dissection in a patient with RP.

Primary infected abdominal aortic aneurysm: surgical procedures, early mortality rates, and a survey of the prevalence of infectious organisms over a 30-year period.

Purpose: The purpose of this study was to analyze the surgical procedures, culture results, and outcomes, and to survey the prevalence of the infectious organisms over a 30-year period in patients with a primary infected abdominal aortic aneurysm (PIAAA).

Methods: A total of 11 patients (1.8%) with PIAAA were surgically treated between 1982 and June 2009.

A transesophageal echocardiographic and cine-fluoroscopic evaluation of an ATS prosthetic valve opening.

Purpose: The effectiveness of the ATS valves includes their durability and the quietness of the valve sound. However, a cine-fluoroscopic study revealed an incomplete opening of the valve leaflet. An overall evaluation of the ATS valve was conducted by transesophageal echocardiography.

Prophylactic reoperation after mitral valve replacement with the Starr-Edwards ball valve: a report of four cases.

Purpose: The Starr-Edwards ball valve was first applied clinically in 1960. In our hospital, this valve has been used since 1963, and some patients have been followed up for 30 years or more. Based on our experience, therapeutic strategies included revalve replacement as a preventive procedure in the absence of valve-related complications.

Prognosis for patients with type B acute aortic dissection: risk analysis of early death and requirement for elective surgery.

Background: The long-term outcome of medical treatment in patients with type B acute aortic dissection (BAD) was assessed and predictors of early in-hospital death were investigated, as well as the need for surgical intervention.

Methods And Results: In the past 11 years, 180 patients were admitted to hospital and medically treated at the time of onset. If the maximum diameter of the dissected aorta exceeded 60 mm, or rapid enlargement or vital organ ischemia were identified, early or elective surgery was performed.

An evaluation study on the quietness of the ATS valve.

Background: The closure sound of the ATS bileaflet mechanical valve is said to be quieter than that of the other mechanical valves. However, the reasons for this are still unknown. In this study, we investigated the reasons for the quietness of the ATS valve closure sound.

40 Years experience in mitral valve replacement using Starr-Edwards, St. Jude Medical and ATS valves.

Background: We have used the Starr-Edwards ball (S-E) valve since 1963, the St. Jude Medical (SJM) valve since 1978, and the ATS valve, since 1993 as the first choice of mechanical valve. In this study, the results with each valve during the 40 years were investigated in single mitral valve replacement (MVR) cases.

A case of aortic valve replacement with St. Jude Medical Regent valve (first implant in Japan).

The St. Jude Medical (SJM) Regent valve was developed as a new mechanical valve by improving the conventional SJM valve. The effective orifice area is wider than that of Hemodynamic Plus (HP) series.

Effects of pulsatile CPB on interleukin-8 and endothelin-1 levels.

Studies on pulsatile and nonpulsatile perfusion have long been performed. However, investigators have not reached a conclusion on which is more effective. In the present study, pulsatile cardiopulmonary bypass (CPB) was investigated in terms of the effects on cytokines, endothelin, catecholamine, and pulmonary and renal functions.
