Myocardial revascularization with radial and mammary arteries: initial and mid-term results.

Background: The radial artery is being used with increasing frequency instead of the saphenous vein in coronary artery bypass grafts. We analyzed the in-hospital and midterm results in patients undergoing coronary artery bypass surgery in whom a combination of arterial grafts was used, including radial artery and one or both internal mammary arteries.

Methods: Between 1995 and 1998, 1,023 patients underwent coronary artery bypass surgery using arterial conduits.

Unsuspected embolic fungal endocarditis of an aortic conduit diagnosed by transesophageal echocardiography.

A 66-year-old man with a history of hypertension and ascending aortic replacement because of a type A dissection had 3 successive embolic events (left lower limb, brain, and spleen). Two consecutive transesophageal echocardiography studies showed mobile masses in the ascending aorta. The patient was reoperated without a certain etiologic diagnosis, and an unsuspected fungal endocarditis caused by an unusual germ (Trichoderma species) was found.

Off-pump coronary operation at the Favaloro Foundation: results in 264 patients.

Background: Our objective was to determine whether complete myocardial revascularization "off pump" was feasible while maintaining the efficacy of conventional surgical techniques.

Methods: 264 patients were operated on between March 15, 1998, and August 26, 1999. A total of 218 (82.

Azygos vein diverticulum.

A 47-year-old woman, diagnosed with a diverticulum of the arch of the azygos vein, underwent surgical treatment. With nonspecific symptomatology, she presented one of the most uncommon anomalies of the large veins.

[Coronary revascularization surgery with arterial conduits. The technic, results and 4-year follow-up in 1023 consecutive patients].

Objective: The main objective of the present study was to analyze the in-hospital and mid term results obtained in 1,023 consecutive patients undergoing coronary artery bypass surgery (CABG) in whom a combination of arterial grafts was used: radial arteries (RA) and one or both internal mammary arteries (IMA).

Methods: From May 1995 to May 1998, 1,023 consecutive patients underwent CABG alone, using arterial conduits (AC) (one or two IMA and RA) for myocardial revascularization. The left internal mammary artery (LIMA) was employed as an "in situ" graft, and the right internal mammary artery (RIMA) as a free graft or "in situ" both in combination with the RA.

Valve operations through a minimally invasive approach.

Background: We analyzed in-hospital results of 87 patients undergoing minimally invasive valvular operations (right parasternal incision through third and fourth cartilages).

Methods: Age was 21 to 84 years (mean, 56.2 +/- 16); 45 patients (51.

Surgical treatment of acute type A dissecting aneurysm, with preservation of the native aortic valve and use of biologic glue. Follow-up to 6 years.

We present an analysis of 59 patients operated on between 1983 and 1987 for acute type A dissecting aneurysm with aortic valve insufficiency. The ascending aorta was replaced with a Dacron tube, the layers of the dissection were unified with gelatin-resorcine-formaldehyde glue, and the natural aortic valve was preserved. Follow-up every 6 months was subject to actuarial analysis.

Deep hypothermia and circulatory arrest as an elective technique in the treatment of type B dissecting aneurysm of the aorta.

The combination of deep hypothermia and circulatory arrest has been used in a variety of cardiovascular surgical techniques and is presented in this article as an elective method in the treatment of type B dissecting aneurysms that may or may not involve the distal aortic arch. Out of 190 patients operated on with acute aortic dissection, 10 patients with type B underwent surgical procedures, between January 1985 and December 1987, four with acute dissection (less than 14 days evolution), and six with chronic dissection (more than 14 days evolution). The approach was by left posterolateral thoracotomy with cardiopulmonary bypass using femoro-femoral cannulation, deep hypothermia, and circulatory arrest.
