What are the 3 different types bypass grafts?
What are the 3 different types bypass grafts?
What are the different types of heart bypass surgery?
- Single bypass. Only one artery is blocked.
- Double bypass. Two arteries are blocked.
- Triple bypass. Three arteries are blocked.
- Quadruple bypass. Four arteries are blocked.
Which graft is best for CABG?
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.
What veins are used for 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).
Are radial artery bypass grafts better than saphenous vein grafts?
The use of radial-artery grafts for coronary-artery bypass grafting (CABG) may result in better postoperative outcomes than the use of saphenous-vein grafts.
What is antegrade cardioplegia?
When solution is introduced into the aortic root (with an aortic cross-clamp on the distal aorta to limit systemic circulation), this is called antegrade cardioplegia. When introduced into the coronary sinus, it is called retrograde cardioplegia.
What is a radial graft?
Radial artery (RA) is the most popular arterial graft after the left internal thoracic artery in both low- and high-risk patients undergoing coronary artery bypass grafting.
What are saphenous vein grafts?
Saphenous vein grafts (SVGs) are the most frequently used conduits for coronary artery bypass graft (CABG) surgery but are associated with 10-year vein graft failure (VGF) rates of 40−50%.
What is a saphenous vein graft used for?
How many types of cardioplegia are there?
Table IV
| Variable | P-value | 95% CI |
|---|---|---|
| Intercept | 0.0033 | 0.6149 |
| Cardioplegia: FR | 0.0416 | 2.2765 |
| Cardioplegia: ST | 0.0140 | 2.4648 |
| Age: 90–319 days | 0.0537 | 1.0058 |
What is the role of K+ in cardioplegia?
Chemically, the high potassium concentration present in most cardioplegic solutions decreases the membrane resting potential of cardiac cells. The normal resting potential of ventricular myocytes is about -90 mV.
What is patency of vascular grafts?
Patency was defined as any flow through both the graft and the native vessel. The graft was determined to be nonpatent if either a stump was present or no flow could be observed.
What is SVG RCA?
Selective saphenous vein graft to right coronary artery (SVG-RCA) angiogram demonstrating patent graft with side to end anastomosis to the RV marginal artery, and distal right posterolateral artery. End to end vein graft limb from mid SVG-RCA to the left posterior descending artery (LPDA).
