On Wednesday morning former President Alberto Fujimori was taken to the Hospital de Neoplasicas, in San Borja, after showing signs of vascular problems.

"His health has been complicated for the past two days, he is under review,” said Congressman Alejandro Aguinaga, Fujimori’s personal physician.

“[He] has vascular problems, it has nothing to do with cancer, I am with him,” Aguinaga said to El Comercio, adding that he could not give any more information.

Fujimori was also taken to Neoplasicas last November, for a checkup, after a fall he suffered in his jail cell.

According to a medical report, made public last year, Fujimori is "chronically ill" but "stable" from a physical and neurological standpoint.

Fujimori was President of Peru from 1990 until 2000, when he fled the country.

In 2009 a three-judge panel of Peru's Supreme Court convicted Fujimori on charges of human rights abuses, declaring that the "charges against him have been proven beyond all reasonable doubt."
