Anatomical terminology |
There are two Pericardial sinuses: transverse and oblique.
- The cul-de-sac enclosed between the limbs of the inverted U of the venous mesocardium lies behind the left atrium and is known as the oblique sinus.
- The passage between the venous and arterial mesocardia—i.e., between the aorta and pulmonary artery in front and the superior vena cava behind—is termed the transverse sinus.[1] Also, the sinus that forms in the pericardial cavity where the dorso-mesentary pericardium reside.
- Can be used to pass ligature during cardiac surgery.
