Fenestrations

Fenestrations are small openings or gaps, often found in biological structures. In the context of medicine, fenestrations can refer to natural openings in the body, such as those in the capillaries, or to surgical openings created for medical procedures.

Anatomy

In the human body, fenestrations are found in various structures. For example, the capillaries have fenestrations that allow for the exchange of substances between the blood and the surrounding tissues. These fenestrations are crucial for the delivery of nutrients and the removal of waste products.

Medical Procedures

In medical procedures, fenestrations are often created surgically. For instance, in a fenestrated endovascular aortic repair (FEVAR), fenestrations are made in the graft to allow for blood flow to the renal and visceral arteries. This procedure is used to treat abdominal aortic aneurysms that involve the renal and visceral arteries.

Pathology

In pathology, fenestrations can refer to abnormal openings in the body. For example, in the case of a fenestrated septum primum, there are multiple fenestrations in the septum primum of the heart, which can lead to a condition known as atrial septal defect.
