Endoleak type IV occurs very rarely and typically was observed 4-8 weeks following implantation of previous generation stentgrafts. Endoleak type II, although relatively common, typically presents early after stentgraft implantation. In our case combined thrombocytopenia-induced endoleaks type II and IV manifested 22 months following stentgraft implantation. The patient presented with abdominal pain and rapid increase in aneurysm diameter. The patient did not require endovascular intervention, medical treatment proved sufficient to relieve clinical symptoms and to prevent progression of the aneurysmal sac. Thrombocytopenia has not manifested itself again so far. The patient is followed-up with increased frequency. It should be noted that occurrence of type IV endoleak, in particular when associated with other type of endoleak, can result from thrombocytopenia. This type of endoleak should be included in differential diagnosis not only in early postinterventional period but also in long-term follow-up, first of all in patients with first generation stentgrafts implanted, featured by porosity of covering material.
