Which artery is used for grafting?

Internal thoracic artery As the most commonly used bypass grafts, the internal thoracic (mammary) artery (ITA) grafts show the best long-term results. In most cases, the artery is left intact at its origin, with the opposite end sewn to the coronary artery below the site of the blockage.

Is radial artery used for CABG?

As compared with the use of saphenous-vein grafts, the use of radial-artery grafts for CABG resulted in a lower rate of adverse cardiac events and a higher rate of patency at 5 years of follow-up. (Funded by Weill Cornell Medicine and others.)

What is a radial artery graft?

The radial artery graft is considered the second option as a conduit after the left internal mammary graft in coronary artery bypass grafting. Multiple studies have shown better patency rate and survival with radial artery graft as compared to saphenous vein graft.

What is Skeletonization of an artery?

Skeletonized conduits are arteries that have been dissected from all surrounding tissues, including accompanying veins, fascia, lymphatics and adipose tissue, leaving the adventitia as the outermost layer.

How do you harvest radial artery?

Open approach for radial artery harvest

1. A curvilinear skin incision, tailored to the edge of the brachioradialis muscle, extends from 1 cm distal to the elbow crease to 1 cm proximal to the wrist crease (Figure 1).
2. Once through the skin, superficial veins are either retracted or divided between clips.

Which artery is used in CABG?

Coronary artery bypass graft surgery usually lasts 3 to 6 hours. But it may take longer depending on how many blood vessels are being attached. Blood vessels can be taken from your leg (saphenous vein), inside your chest (internal mammary artery), or your arm (radial artery).

Why is Lima used for CABG?

The Left internal mammary artery (LIMA) is considered the conduit of choice for the surgical treatment (CABG, coronary artery bypass grafting) of Coronary artery disease (CAD) due to its superior long term potency than the other conduits.

What is Lima harvesting?

The first is the pedicled LIMA harvesting. In this technique, LIMA is excised together with the surrounding tissues. The LIMA that comprises intrathoracic fascia, veins around the artery, adipose tissue and sometimes muscular tissue is called a pedicled LIMA.

What is skeletonized Lima?

This video shows the basic technique of skeletonized left internal mammary artery (LIMA) harvesting. Skeletonization is an advanced technique of graft harvesting for coronary artery bypass grafting (CABG), and while it requires meticulous attention, it has many advantages.

What vein is harvested for bypass surgery?

During the operation. Coronary artery bypass graft surgery usually lasts 3 to 6 hours. But it may take longer depending on how many blood vessels are being attached. Blood vessels can be taken from your leg (saphenous vein), inside your chest (internal mammary artery), or your arm (radial artery).

What is Lima and Rima in CABG?

In the Total Arterial Revascularization technique of Bypass Surgery, the internal mammary arteries (LIMA & RIMA) from the left and right sides of the chest respectively are used.

What is LIMA to LAD procedure?

What is LIMA to LAD? LIMA LAD is a life-saving coronary artery bypass procedure that involves the left internal mammary artery and the left anterior descending artery. It opens the heart’s blood flow, saving the life of the patient.

What happens when the radial artery is removed?

Brodman et al. [23] reported that radial artery removal resulted in an 11% increase in diameter of the ulnar artery and a 20% increase in blood flow velocity (as measured by color flow and pulsed Doppler scanning, respectively).

What is a pedicle graft CABG?

The old-style internal mammary artery bypass grafting, classically known as pedicle grafting, includes a circular rim of tissue around the graft. Bilateral pedicled internal mammary arteries, especially among diabetic patients, have been reported to cause complications in the sternum like sternal osteomyelitis.

Why is Lima in CABG?

What is the most popular vein to harvest for CABG?

Endoscopic vein harvesting (EVH) is a procedure to harvest the greater saphenous vein (GSV), the most widely used conduit in coronary artery bypass graft surgery.

What is the role of diltiazem in the treatment of radial artery grafts?

The routine use of arterial grafts in coronary surgery is facilitated by peroperative adjunction of antispasmodic drug to reduce the event of spasm. Diltiazem has been favoured in most clinical studies devoted to the radial artery graft.

How do you harvest a radial artery?

Open approach for radial artery harvest A curvilinear skin incision, tailored to the edge of the brachioradialis muscle, extends from 1 cm distal to the elbow crease to 1 cm proximal to the wrist crease (Figure 1). Corroboration of the appropriate position of the skin incision can be obtained by palpating the radial pulse proximally and distally.

Does diltiazem prevent or reverse rheumatoid arthritis contractions?

Diltiazem, which is used empirically to prevent RA vasospasm, had little effect on human RA contractions (receptor-independent and receptor-dependent). Organic nitrates inhibited and reversed RA contractions.

How is the radial artery prepared for hydrostatic dilation?

The radial artery was prepared by hydrostatic dilation with papaverine (1%) and nicardipine was administrated at 0.25 microgram/kg/min and titrated according to the arterial systemic pressure. Operative mortality was 4% (sepsis). There was no evidence of perioperative MI nor hypoperfusion syndrome. Mean CKMB level at 18 hours was 36 micrograms/l.
