Haematogenous tuberculosis

ABSTRACT

Haematogenous tuberculosis is a tuberculosis affection of multiple organs not related to each other except by blood stream. In this study there were 40 patients with haematogenous tuberculosis out of 1419 patients with different chest diseases admitted to Taif Chest Hospital [which is the biggest hospital for chest diseases in the Kingdom of Saudi Arabia] during a period of one year forming incidence of 2.82%, this indirectly denotes that kingdom Saudi Arabia is an intermediate prevalence area according to WHO Classification. The total number of tuberculosis patients whether pulmonary or extrapulmonary admitted to Taif chest hospital during that period was 577, out of them 40 patients were haematogenous tuberculosis [6.93%] which is a high incidence one and this raises the importance of BCG vaccination as BCG does not prevent infection but prevent haematogenous dissemination
