Catastrophic arterial reactivity during primary antiphospholipid syndrome - A case report

Arterial reactivity leading to acute thrombosis at the site of a needle sti ck injury has never been described during antiphospholipid syndrome. The au thors report a case characterized by a succession of thrombotic events occu rring during or immediately after arterial angiographies or arterial surger y, in which catastrophic arterial reactivity can be strongly suspected. In this particular patient, it can be postulated that damage to the endothelia l cells of the vessels injured during manipulation may have precipitated or aggravated the preexisting susceptibility to thrombosis.
