Situs Inversus Totalis

"Situs inversus is a short form of the Latin phrase “Situs inversus Viscerum” meaning “inverted position of the internal organs, as first described by Marco Severino in 1643. All dead, aborted foetuses are dissected in the Department of anatomy of KIMS, Narketpally. The index case showed the Situs inversus totalis. The incidence is about 1:10,000 live people. Normal human development results in an asymmetrical arrangement of the organs within the chest and abdomen. Typically, the heart lies on the left side of the body (levocardia), the liver and spleen lie on the right. Mirror image i.e. transposition of abdominal and thoracic viscera is termed Situs inversus totalis. It has shown the anomalies of rotation, fixation during the development, a perfect mirror image. Such relationship between the organs is does not lead to functional problems in most. The apex of the heart is located on the right side of the thorax, the stomach and spleen on the right hypochondriac region in the abdomen and the large lobe of the liver and gallbladder on the left side. The left lung is tri-lobbed and the right lung bi-lobbed, and blood vessels, nerves, lymphatics and the intestines are also transposed (Figure 1).
