Four incisions for an appendectomy, corresponding to the order listed. Hasson Entry: The two red lines mark the sites of the 5mm laparoscopic ports. The blue line above the umbilicus marks the site of the camera port Surgeons perform a laparoscopic appendectomy. In general terms, the procedure for an open appendectomy is:
Oxygenated blood is directed from the left ventricle to the aorta using a Gore-Tex patch. The VSD is also sealed with the patch. The pulmonary valve is surgically closed.. From the right ventricle to the pulmonary bifurcation, a synthetic conduit and a valve are constructed, which lets oxygen depleted blood to flow into the lungs for reoxygenation.
A ventriculotomy is a heart surgery that involves an incision into one or both ventricles. It is a component of many heart surgeries, including infarctectomy and many congenital heart defect surgeries. In the long-term, a prior ventriculotomy can increase the risk of ventricular arrhythmia.
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
In a normal heart, the sequence of blood is from vena cava to right ventricle, then to the lungs and finally from lungs to the left ventricle to be circulated throughout the body. In patients with transposition, the order is from cava to left atrium and ventricle, then to the lungs and finally to the right side of the heart to be pumped out to ...
This allows the blood, a mixture of oxygenated and deoxygenated, to be pumped to the body via the morphologic right ventricle, through the pulmonary valve. At this point in the surgery, the right ventricle is directly connected to systemic circulation through the Neoaorta or the reconstructed aortic outflow track.
The first uses a cardiopulmonary bypass machine, a machine which takes over the functions of the heart and lungs during surgery by circulating blood and oxygen. With the heart in cardioplegic arrest , harvested arteries and veins are used to connect across problematic regions—a construction known as surgical anastomosis .
Dextro-Transposition of the great arteries (also known as dextro-TGA) is a cyanotic heart defect in which the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. This switch causes deoxygenated blood from the right heart to be pumped immediately through the aorta and circulated throughout the body and ...
