[Acute abdominal pain due to splenic infarction in a patient with heterozygous sickle cell disease exposed to high altitude].
Hemoglobinopathy S, Depranocytosis or Sickle Cell Disease is the most common hemoglobinopathy in the world. In its heterozygous form (Sickle Cell Trait), it affects 8% of the black population in the U.S. and 25% of the black population in Africa, and is found less frequently in the Mediterranean area, India, Middle East and Latin America. The basic alteration is a substitution of glutamic acid by valin in the sixth position of the beta globin chain, which causes polymerization at low oxygen tension thereby distorting the structure of erythrocytes and increasing blood viscosity, which, in turn, generates obstructions of the capillary arterial blood flow to different areas of the body thus causing microinfarctions. Although Splenic Infarction is rare, it is recognized as a serious complication of Heterozygous Sickle Cell Disease (Sickle Cell Trait). We present the case of a 21 year-old mestizo male patient who came in with an acute case of abdominal pain after arriving to work in the Casapalca mining city (located in the Peruvian Andes at 4200 m.a.s.l.) and was referred to our Hospital in Lima for exams. We present the case because it is an unusual cause of acute abdominal pain, and because this condition is rare in Peru and there are few publications about it.
