Epidural catheter placement is a widely utilized method for administering anesthesia during various surgical procedures. Similar to other medical interventions, epidural insertion carries potential complications, including but not limited to breakage, migration, kinking, abscess formation, radiculopathy, and hematoma development.

1. Abstract
A classic example of the symbiosis of structural and functional perturbations is vascular occlusion due to atherosclerosis. Narrowing of the blood vessel is already a serious danger, because very often the formed elements in the blood coagulate as blood clots – larger structural formulas.
