What are the disadvantages of minimally invasive bypass surgery?

The disadvantages of mini-incision minimally invasive bypass surgery mainly include conversion thoracotomy, long learning curve, high requirements for myocardial protection, not applicable to all patients, and high cost. The disadvantages of mini-incision minimally invasive bypass surgery mainly include the following: 1. Conversion thoracotomy: mini-incision minimally invasive bypass surgery needs to be performed under the condition of beating heart, and the surgical operation requirements are high. If there are difficulties or emergencies during the operation, it may be necessary to convert to thoracotomy and change to traditional median thoracotomy. 2. Long learning curve: Compared with traditional median thoracotomy, the learning curve of mini-incision minimally invasive bypass surgery is longer, requiring higher surgical skills and experience. 3. High requirements for myocardial protection: Due to the small incision, the surgical field is limited, and the requirements for myocardial protection are higher. If the myocardial protection is not appropriate, it may lead to complications such as myocardial infarction. 4. Not applicable to all patients: Although minimally invasive bypass surgery with small incision has the advantages of less trauma and faster recovery, it is not applicable to all patients. For some patients with complex conditions and severe coronary artery disease, traditional median thoracotomy may be required. 5. High cost: Because small incision minimally invasive bypass surgery requires the use of special instruments and equipment, the cost of surgery is relatively high. It should be noted that minimally invasive bypass surgery is a relatively advanced surgical method, with the advantages of less trauma and faster recovery, but there are also some disadvantages. When choosing a surgical method, patients should consider comprehensively according to their own conditions and doctors' suggestions. At the same time, no matter which operation method is selected, it should be performed in a regular hospital and operated by experienced doctors to ensure the safety and effectiveness of the operation.
