What is modified Blalock-Taussig shunt?

What is modified Blalock-Taussig shunt?

(MBTS) Most often a modified Blalock-Taussig shunt (MBTS) is placed in the neonatal period to correct low oxygen saturation due to insufficient blood flow to the lungs, resulting from the new- born’s particular form of congenital heart disease.

How does Blalock-Taussig shunt work?

The Blalock-Taussig (BT) shunt mimics the role of the ductus arteriosus, meaning it allows blood to flow from a major artery through a connection to the pulmonary artery. Not only does this allow more blood to be oxygenated by the lungs, it also encourages the pulmonary arteries to grow, making the next surgery easier.

What is a BT shunt murmur?

They occur when there is a constant shunt between a high and low pressure blood vessel. Examples: patent ductus arteriosus (PDA) and systemic arterio-venous fistulas. This may also occur in surgically placed shunts such as a BT shunt between the aorta and the pulmonary artery.

When was first Blalock-Taussig shunt?

The procedure was first performed in a 15-month-old girl with tetralogy of Fallot in November 1944 at Johns Hopkins University Hospital in Baltimore, Maryland (USA). A modified Blalock-Taussig shunt technique using “plastic prostheses” was first described by Klinner in 1962 4.

Is Blalock Taussig shunt open heart surgery?

This is a closed-heart procedure. The BT shunt mimics the role of the ductus arteriosus. It is often put in place after the ductus closes naturally. Shunts are usually used for four to five months, until the child outgrows them and a second operation or definitive repair is needed.

What do you mean by shunt?

A shunt is a small tube that goes inside the body to drain fluid. Although shunt usually refers to a tube that drains blood or other fluid out of a part of the body, shunt also means to bypass. If a train is shunted, it’s diverted from the main track onto a side track.

Who invented the BT shunt?

Objective: To describe the contribution of Vivien Thomas to the scientific and technical development of the Blalock-Taussig shunt. Design: Review of the literature and of the papers of Vivien Thomas, Alfred Blalock, and Helen Thomas.
