[Minimum invasive coronary operations: indications, technique, contra-indications]
Insights
Minimally invasive coronary artery bypass surgery, including off-pump coronary artery bypass (OPCAB) and robot-assisted techniques, reduces post-operative complications and mortality. These advanced methods offer safer alternatives to traditional bypass surgery.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Procedures
- Surgical Technology
Background:
- Traditional coronary artery bypass surgery using cardiopulmonary bypass (CPB) is associated with complications like postperfusion syndrome, including neurological and neurocognitive deficits.
- The development of 'beating heart' surgery without CPB (off-pump technologies) emerged in the 1970s to mitigate these risks.
Purpose of the Study:
- To review the evolution and application of off-pump coronary artery bypass (OPCAB) and minimally invasive techniques.
- To highlight advancements in surgical approaches aimed at reducing postoperative complications and mortality in coronary revascularization.
Main Methods:
- Evolution of off-pump coronary artery bypass (OPCAB) techniques since the 1980s.
- Development of mini-invasive surgical approaches (thoracotomy, transdiaphragmatic, transabdominal).
- Integration of endoscopic techniques and robot-assisted coronary artery bypass (RAVECAB) for enhanced surgical precision.
Main Results:
- Off-pump coronary artery bypass (OPCAB) has been widely adopted, facilitating procedures with stabilizers.
- Endoscopic and robot-assisted technologies have further refined minimally invasive coronary revascularization.
- These approaches are applicable to select patients, demonstrating a potential decrease in postoperative complications and lethality.
Conclusions:
- Minimally invasive coronary revascularization, including OPCAB and RAVECAB, offers significant advantages over traditional CPB methods.
- These advanced surgical techniques are crucial for improving patient outcomes and reducing surgical risks in coronary artery disease treatment.
Abstract:
On the basis of the experience with the contemporary coronary chirurgery with classical bypass technology under the conditions of cardiopulmonary bypass (CPB) are specified the complications that occurred in the patient. These complications, generalized as 'postperfusion syndrome' are filled out with common brain complications like embolism, insultus and these in neurokognitive sphere of the brain activity. For decrease the complications by the coronary operations from 1975 are developed new technologies for coronary revascularization under the conditions of 'beating heart' without CPB (off-pump technologies). From 1980 Benetti F. and Buffalo (1981) in Latin America widely use the coronary revascularization of 'beating heart' without CPB (off-pump coronary artery bypass = OPCAB). For the realization of these operations are developed miniinvasive operative technologies through different operative admissions: small anterolateral thoracotomy, dorsolateral thoracotomy, xiphoid transdiaphragmatic, transabdominal etc. A considerable facilitation by OPCAB is achieved with using vacuum or mechanical stabilizers of the cardiac activity. In the course of last decade OPCAB operations are taken with endoscope technics Mack and coll. (1997), Wolf (1998) etc. The technology for decreasing of the operative technology is developed by adopting robot assistance by the coronary bypass operations (RAVECAB) from Boyd and coll. (2001), Kiaii and coll. (2000), Mohr, Falk and Diegeler (1999) etc. The miniinvasive coronary revascularization can be applied by exact draft patients and help for decreasing the postoperative complications and the lethality.
