1. Indications

The necropsy (autopsy) is indicated for various reasons, including:

• Legal or Forensic Investigation - To determine the time and manner of death and the events leading up to it.
• Clinical Investigation - To ascertain the cause of death and gain insights into the pathological processes of diseases.
• Academic Research - To enhance medical knowledge and improve healthcare standards to prevent future deaths.

2. Procedure

The necropsy procedure involves several detailed steps to ensure a thorough examination of the body:

• External Examination - The procedure begins with a comprehensive external examination of the body. This includes taking photographs, noting the condition of clothing, and observing the body position. Any dirt, blood, or chemical residues are collected for analysis. Ultraviolet light may be utilized to identify fluid deposits on the skin or clothing, and samples of hair and nails may be taken for forensic purposes. Radiographic examinations may also be performed to detect any new or healing bone fractures.
• Incision and Accessing Internal Organs - To examine the internal organs, a specific incision technique is employed. This may involve a “Y” incision from the shoulders down to the sternum and continuing to the pubic bone, a “T” incision across the collar bones and down to the pubic bone, or a midline vertical incision from the neck to the pubic bone. The ribs are transected along both sides, allowing the ribs and sternum to be lifted as a single unit to expose the chest cavity.
• Examination of the Heart and Major Vessels - The pericardial sac is opened to access the heart. Blood samples may be collected from the inferior vena cava or pulmonary veins. The pulmonary artery is examined for blood clots, and the major vessels, including the inferior vena cava, pulmonary veins, aorta, pulmonary arteries, and superior vena cava, are transected to facilitate the removal of the heart.
• Removal of Lungs and Abdominal Organs - The left lung is removed by transecting the bronchus, artery, and vein at the hilum, followed by the right lung. The abdominal organs are then examined in relation to the blood vessels before being removed either individually or as a single block by dissecting along the vertebral column. Each organ is weighed and measured, and blocks of tissue may be taken for further microscopic examination.
• Closure of the Body - Upon completion of the autopsy, the body cavity is lined with an appropriate material. The internal organs are sealed in a plastic bag and returned to the body. Finally, the abdomen and chest flaps are re-approximated and closed to complete the procedure.

3. Post-Procedure

After the necropsy is completed, the body is prepared for final disposition. The internal organs are returned to the body, and the incisions are closed securely. Documentation of the findings is crucial, as it contributes to the overall understanding of the case and may be used in legal or clinical contexts. The collected samples and tissue blocks may be processed for microscopic examination, which can provide further insights into the pathological conditions observed during the necropsy. The results of the necropsy can have significant implications for public health, forensic investigations, and medical education.
