Summary
An individualized off-pump approach in all internal thoracic artery (AITA) composite graft revascularization (AITACR) is safe and effective. This strategy minimizes neurological complications and yields excellent early results.
Area of Science:
- Cardiovascular Surgery
- Neurological Complications
- Graft Revascularization
Background:
- Minimizing postoperative neurological complications is crucial in cardiac revascularization.
- All internal thoracic artery (AITA) composite graft revascularization (AITACR) aims for optimal long-term outcomes.
Purpose of the Study:
- To report early results of an individualized off-pump approach within an AITACR program.
- To assess the safety and efficacy of this strategy in reducing neurological complications.
Main Methods:
- Operative method (on-pump vs. off-pump) determined by institutional criteria.
- Evaluated early neurological outcomes in 199 patients (157 men, 42 women; mean age 67.3 years).
Main Results:
- No operative mortality observed.
- Three patients (1.5%) experienced postoperative cerebral infarctions, potentially linked to atrial fibrillation.
- Off-pump patients were older and had higher prevalence of comorbidities.
Conclusions:
- Individualized off-pump approach in AITACR is safe and effective.
- Achieved excellent early neurological outcomes with acceptable morbidity.
- This strategy appears reasonable for selected patients.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
