Aortic Surgery Glossary

Breakdown of a surgical connection between vessel segments, resulting in blood leakage at the suture line.

Combined dilatation of the aortic annulus and ascending aorta without discrete aneurysm formation.

A localized enlargement of the aorta exceeding 150% of normal diameter, requiring precise description in surgical report...

The anatomical configuration of great vessel origins from the aortic arch, with normal and variant patterns affecting su...

Surgical technique involving rerouting of arch vessels to enable proximal landing zone extension for endovascular repair...

Congenital underdevelopment of the aortic arch resulting in narrowing and potential obstruction to systemic blood flow.

Congenital heart defect characterized by complete discontinuity of the aortic arch, resulting in absence of luminal conn...

The minimum pressure required to achieve complete aortic occlusion during cross-clamping procedures.

The duration during which the aorta is cross-clamped to create a bloodless operative field.

The ability of the aorta to distend and recoil in response to changes in blood pressure during the cardiac cycle.

Disparity in elastic properties between native aorta and synthetic grafts, leading to altered hemodynamics and potential...

Surgical instrument used to temporarily occlude the aorta during cardiac procedures, stopping blood flow through the ves...

The internal luminal area of the aorta measured perpendicular to the vessel's central axis. Used to calculate flow veloc...

Displacement of an aortic valve cusp below the level of the aortic annulus during diastole.

A calculated ratio of aortic diameter to body surface area used to normalize aortic dimensions for patient size. Helps s...

A life-threatening condition where blood separates the layers of the aortic wall, creating a false lumen.

A surgical procedure creating an opening between the true and false lumens in aortic dissection. Used to equalize pressu...

Retrograde blood flow in the aorta during diastole, typically indicating aortic regurgitation.

The rate of aortic diameter increase over time, typically measured in millimeters per year. Used to guide timing of surg...

The opposition to pulsatile blood flow in the aorta, determined by vessel elasticity, resistance, and wave reflection pr...

Hemodynamic condition where differences in elastic properties between native aorta and prosthetic graft material affect...

Invagination of the aortic intimal flap into the true lumen, typically seen in chronic aortic dissections.

Elongated, kinked aortic arch without hemodynamically significant obstruction.

Backward flow of blood from the aorta into the left ventricle during diastole due to incompetent aortic valve.
