In vitro effects of L-carnitine on coronary artery bypass grafts.

Background: The gold standard treatment for multivessel coronary revascularization is coronary artery bypass grafting. The internal mammary artery and saphenous vein grafts are the conduits most frequently used for these operations. Spasm of arterial and venous grafts is a significant problem during the operation.

Harvesting of the radial artery: subfasciotomy or full skeletonization: a comparative study.

Background: Long fasciotomy of the posterior aspect of the radial artery (RA) for the purpose of sympathectomy is one of the surgical techniques for the preparation of this graft. We compared the early results of this technique with those of the RA graft harvested as a pedicle in the conventional fashion.

Methods: The study patients have been selected from the patients who underwent coronary artery bypass grafting (CABG) using the RA graft harvested either with a long posterior fasciotomy (group 1) or as a whole with a pedicle in the classical manner (group 2).

[Missed aortic transection following blunt trauma: a case report].

Missed vascular injuries following blunt traumas can lead to fatal clinical conditions that require an emergency intervention. Aortic transection (AT) is the most fatal complication of these missed vascular injuries. In this case report an AT that developed following a blunt trauma is presented.

The effects of lipid-lowering therapy on graft patency in coronary bypass surgery patients.

Background: Our aim was to investigate the effects of lipid-lowering treatment (LLT) on graft patency in coronary artery bypass grafting (CABG) patients.

Methods: A total of 209 CABG patients (95 men, 45%) with a total cholesterol level above 200 mg/dL and a low-density lipoprotein level above 100 mg/dL were included. Patients were divided into 2 groups on the basis of administration of LLT after CABG: group 1 received LLT after the operation (those patients undergoing operations after 1998, n = 102, 49% male) and group 2 did not receive LLT after the operation (those patients undergoing operations between 1992 and 1998, n = 107, 42% male).

Transcutaneous axillary artery cannulation.

The axillary artery may be an alternative cannulation site for patients with diffused atherosclerosis, aortic dissection, and aneurysm. There are different techniques for axillary artery cannulation that can be performed easily with a transcutaneous approach. Small incision necessity, less dissection, and good wound healing are other advantages of this technique.

[Single clamp technique in elderly patients undergoing coronary artery surgery].

Objective: The results of single clamp and partial clamp techniques were retrospectively compared in elderly patients (>70 years) undergoing coronary artery bypass grafting operation (CABG).

Methods: A total of 244 elderly patients undergoing CABG between January 1995 and March 2002 in our center were studied. Single-clamp technique was used in 32 cases (Group 1) and partial-clamp technique was used in 212 cases (Group 2).
