Other organ removal methods include the Gohn Letulle or modihed Rokitansky methods in which the organs are removed en bloc all together . This type of removal allows the internal viscera to be examined while they are still connected together. Some pathologists always remove organs en bloc. The author has found the Gohn method useful when examining infants with multiple cardiac and other birth defects. There is no right or wrong method of dissection the aim is simply to perform a complete autopsy and to provide a detailed description of that autopsy. 99 100 Color Atlas of the Autopsy HEART EXCISION FIGURE A - C Heart removal cutting the inferior vena cava. The inferior vena cava is cut as are the pulmonary veins pulmonary arteries and aorta. The heart is held in the left hand in these figures. Blood flows from the cut vessels if the blood is not clotted decomposed or mostly absent from the body. In cases of severe hemorrhage there is a notable absence of blood at this moment of the autopsy. Organ and Tissue Removal 101 FIGURE A Cutting the pulmonary artery. The left pulmonary artery is cut as is the left pulmonary vein. B Checking for pulmonary embolus. The pulmonary artery is checked for a clot thromboembolus . FIGURE Pulmonary embolus. The long blood clot depicted was taken from the inferior vena cava. A large pulmonary embolus is seen in the pulmonary artery as well. These clots emboli can move up from the lower leg veins or less commonly from the pelvis or upper arm veins to the right heart and then out to the pulmonary arteries. If these thromboem-boli are large enough they can cause immediate cardiac .
