The compliance test is an important evaluation method that assesses the ability of a vascular scaffold to expand and contract in response to changes in blood pressure and flow, mimicking the behavior of natural blood vessels. In this study, compliance analysis of the vascular grafts was conducted using a peristaltic pump to apply a liquid within the grafts. The pressure was adjusted to two levels, representing lower (80 mmHg) and higher (120 mmHg) pressures, which are indicative of average normal blood pressure in the human body. To measure compliance, the outer diameter of the grafts was recorded under different pressure conditions using a digital camera. The recorded images were then analyzed using ImageJ and Photoshop 6.0 (Adobe) software to calculate the changes in graft diameter. The compliance was determined using the following equation ( ):
