Patient History and Line of Treatment at SIMS Hospitals

The 66-year-old gentleman presented with severe chest pain and cough to a local hospital in Andhra Pradesh. Surprisingly, the local doctor looking at the Chest Xray diagnosed him with SitusInversusTotalis - An extremely rare clinical condition from birth, in which all the right-sided organs are present on the left side and the left-sided organs of the body are present on the right side. In short, it is a case of mirror anatomy. To complicate further, the patient also had an acute Type A Aortic Dissection requiring a high risk emergency surgical procedure, in addition to severe long standing infection in both the lungs (Chronic Bronchiectasis).

Owing to the rarity of his medical condition and the need for a challenging and complicated surgery, (as surgeons they were not well-versed in operating such a patient, and the hospital not well equipped to meet such rare condition), the local doctors promptly referred him to SIMS Hospitals, Vadapalani, Chennai.

Elaborating on the case and the rare condition of the patient, Dr. VV. Bashi Director and Senior Consultant - the Institute of Cardiac & Advanced Aortic Diseases, said, "SitusInversus is a very rare medical condition, reported in 0.01% of the population or about 1 person in 10,000, where it seldom causes any symptoms and is so rare that the person may not even know they have it. They will continue to live a standard healthy life, without any complications related to the medical condition until they visit a doctor for a different reason.

In this case, the patient has been diagnosed with acute Type A Aortic Dissection due to his severe chest pain and cough. He had bilateral bronchiectasis. The CT Aortogram revealed his anomalous anatomy, where his major organs, including heart, liver, gallbladder and spleen were on the exact opposite side of where they should have been. They all were functioning normally, which perhaps was the reason the patient didn't know he was a 1 in 10,000 human for seven decades. After performing all the necessary medical tests, the patient was planned for surgery. His aortic dissection was extending from the aortic valve to the abdominal part of the aorta. His aortic valve was having severe leakage as well.

Hence, he was planned for complete replacement of the intrathoracic aorta - called as Bentall's procedure with aortic arch replacement. During the course of the 5½ hours of surgery, we did face several challenges owing to the rarity of the case and that no such operation was done earlier on a patient with SitusInversusTotalis.

As surgeons we had to orient ourselves to operate from the opposite side (mirror image) of the normal process to change the patient's aortic valve, ascending aorta, and aortic arch, (the one which supplies blood to the brain, head, neck, and arms) - so as to prevent the risk of decreased blood flow to the organs or the rupture of the aorta, which could potentially be life-threatening to the patient. Today, after a month we are glad that the patient has recovered well post the surgery and is doing fine going about his daily routine.

To our knowledge, this is the first Major aortic operation done in a patient with bilateral bronchiectasis with SitusInversusTotalis and Dextrocardia (Kartagener syndrome) in India."
