Answer 1

Total Anomalous Pulmonary Venous Connection


Total anomalous pulmonary venous connection is a rare condition in which the pulmonary veins are connected to the heart's upper-right chamber (the right atrium) instead of its upper-left chamber (the left atrium).

Pulmonary veins carry oxygen-rich blood from the lungs to the heart. Normally, they carry it to the left side of the heart, which pumps this oxygen-rich blood into the body. But this defect causes blood to flow from the lungs to the right atrium instead.

In the right atrium, the oxygen-rich blood mixes with the oxygen-poor blood entering the heart from the body. From the right atrium, this mixture of oxygen-rich and oxygen-poor blood flows through a hole called an atrial septal defect (ASD) and into the left atrium. The left atrium sends blood to the left ventricle, which pumps blood into the body.

When oxygen-poor blood from the right atrium is pumped into the body along with oxygen-rich blood from the lungs, the fingers, toes, and lips may appear blue. This condition is called cyanosis.

How is it treated?

Surgery is used to connect the pulmonary veins to the left atrium and to close the atrial septal defect. When surgery is done early enough, the long-term outlook is very good. Still, the child will need lifelong follow-up to make sure that a blockage does not develop in the pulmonary veins. There is also an increased risk for an abnormal heart rhythm (called an arrhythmia).

Answer 2

Definition of venous :

means relating to the veins, blood vessels which carry blood toward the heart. All veins, except the pulmonary vein, carry blood that contains no oxygen, thus giving it a bluish color.

Venous Congestion

When you sit or stand for prolonged periods of time, the blood in the veins of your legs has difficulty returning to your heart because of the effects of gravity. Activity of the muscles of your calf are needed to contract (squeeze) and propel (push) the venous blood up your legs and back to your heart. Damage or disease of the leg veins and lack of calf muscle activity leads to congestion (pooling) of venous blood in your legs.

Extended periods of venous congestion causes the legs to swell. Damaged or diseased leg veins that are congested may be more visible. They may even protrude and look like ropes wrapped around your legs. These distended and twisted veins are called varicose veins. Blood clots can also occur from the continued pooling of venous blood in the legs.

You may already be familiar with or experience symptoms common with venous congestion:
Swollen ankles
Calf tightness
Heavy or achy feeling in the legs
Reddish brown pigmentation spots
Brawny coloring of the skin above your ankles
Scaly, leathery, or itchy skin on your legs.
