What is pulmonary recess?
The right pulmonary venous recess is one of the pericardial recesses forming a small space within the pericardium. It arises from the pericardial cavity proper located between the right superior and inferior pulmonary veins, posterior to the left atrium. It invaginates towards the oblique pericardial sinus.
What is prominent pericardial recess?
The pericardial recesses are small spaces in the pericardial cavity arising from the transverse pericardial sinus that are formed by the reflections of the pericardium. Pericardial fluid can pool in these recesses, mimicking mediastinal lymph nodes or pathology.
What is the right inferior pulmonary vein?
The right superior pulmonary vein drains the right upper and middle lobe. The right inferior pulmonary vein drains the right lower lobe. The anatomical relationship of the junction between the pulmonary veins and the epicardium of the left atrium is different depending on the person.
What does fluid in the pericardial recess mean?
A pericardial recess with prominent fluid may simulate hypodense lymphadenopathy or a cystic mass, especially in the setting of known primary malignancy. Typical clinical scenario A pericardial recess is typically incidentally found on chest CT imaging.
Where is pericardial recess?
The posterior pericardial recess is located posterior to the distal segment of the right pulmonary artery and on the medial side of the right bronchus. The postcaval recess is located behind and on the right lateral aspect of superior vena cava (Fig. 4A).
How is Pericardiocentesis performed?
During pericardiocentesis, a doctor inserts a needle through the chest wall and into the tissue around the heart. Once the needle is inside the pericardium, the doctor inserts a long, thin tube called a catheter. The doctor uses the catheter to drain excess fluid. The catheter may come right out after the procedure.
Where is the pericardial recess?
The oblique sinus extends superiorly behind the right pulmonary artery and medial to the bronchus intermedius, where it is called the posterior pericardial recess. Fluid in the posterior pericardial recess may be mistaken for peribronchial or subcarinal lymph nodes (,Fig 14,,).
What is right pulmonary vein?
Two main pulmonary veins emerge from each lung hilum, receiving blood from three or four bronchial veins apiece and draining into the left atrium. The right main pulmonary veins (contains oxygenated blood) pass behind the right atrium and superior vena cava; the left in front of the descending thoracic aorta.
What are the names of the pulmonary veins?
There are typically four pulmonary veins, two draining each lung:
- right superior: drains the right upper and middle lobes.
- right inferior: drains the right lower lobe.
- left superior: drains the left upper lobe.
- left inferior: drains the left lower lobe.
Is fluid around the heart serious?
This condition is called pericardial effusion. Fluid around the heart puts a strain on this organ’s ability to pump blood efficiently. This condition can have serious complications, including death, if it isn’t treated.
How long can you live with fluid around your heart?
More specifically, the fluid appears between the membrane sac lining that surrounds the heart, the pericardium, and the heart itself. This condition can come on quickly, sometimes in less than a week. In chronic cases, it can last for more than 3 months.
What is the transverse sinus of the pericardium?
The transverse pericardial sinus is the transverse communication between the left and right parts of the pericardial space proper behind the two outflow arteries of the heart.
