Ghon autopsy technique

Last Updated on Fri, 10 Feb 2023 | GENERAL POLICIES ADULT AUTOPSIES After the external descriptions, the body is weighed and body length is determined; roentgeno-graphic studies may be needed at this time. This is followed by the Y-shaped primary incision and, if indicated, removal of material from the abdomen for microbiologic study. Subsequent steps include collection of abdominal effusions and exudates; search for hernias; incision of anterior At this point, the techniques may be varied according to personal preference or the type of lesion. En masse removal ( Special attention must be paid to the removal of the neck organs and the floor of the mouth. Whether these structures are removed together with the chest organs or as a separate tissue block, lacerations of the skin in the neck area or even of the lips may occur if the prosector is inexperienced or works hastily. Furthermore, the prosector can easily cut or stab the assisting hand during the removal of the soft palate and the floor of the mouth. These procedures should not be attempted without the guidance of an experienced preceptor; work should be slow and deliberate in these areas. (See also below under, "Lesions of Face, Arms, or Hands.") In medicolegal autopsies, particularly in cases of suspected strangulation, extensive skin incisions of the neck area are indicated and permitted (6). In these instances, the brain should be removed first so that blood is drained from the neck and the chance of an artifactual...

This procedure and its many variations, such as the “maze,” are becoming the mainstream treatment for atrial fibrillation owing to limitations of antiarrhythmic drugs. The incidence of this complication rate has been reported to be from 0.01% to 1%. Results.— The initial presenting symptoms included neurologic symptoms, chest pains, epigastric discomfort, and sepsis. Transesophageal echocardiogram in 4 cases showed no evidence of thrombus or vegetation, however, 2 cases had evidence of atrial esophageal fistula. The autopsy findings included 5 atrial esophageal fistulas and 1 esophagopericardial fistula. Atrial esophageal fistulas were small and could be detected without difficulty when the en bloc Letulle technique was used and would have been easily missed by the Virchow method. The immediate causes of the deaths were myocardial ischemia, septic emboli to brain and heart, hypovolemic shock secondary to exsanguination, stroke, and coagulopathy. Esophageal fistula (EF) is one of the most serious compl...

Autopsy Definition An autopsy is a surgical procedure performed on a corpse after death (a period called, “post-mortem.”). It is typically conducted in an attempt to understand the person’s cause of death. The autopsy will be conducted by a trained physician who has specialized in pathology, as determining the cause of death will require a vast understanding of disease and injury. A brief history of autopsies will tell us that humans have been performing autopsies since the dawn of time, it seems. There is historical data to support that autopsies were performed in ancient Egyptian times. Ancient Egypt was notably known for performing elaborate death rituals and valuing the afterlife, so it makes sense that an autopsy would be part of that ritual. However, a distinction between those early times and now is that whereas ancient Egyptian examiners were removing organs for preservation, autopsies today are done with the intention to explain disease and death.

There are different correct ways to perform it, but the Letulle method has become the principle protocol for training pathologists. This particular method finds the pathologist or medical student commencing the dissection at the abdomen. After piercing the abdominal area, the abdominal organs will be removed in one block per this method – understanda...
