RESUMO
Mycotic false aneurysm caused by local arterial injury from attempted intravenous injections in drug addicts remains a challenging clinical problem. The continued increase in drug abuse has resulted in an increased incidence of this problem, particularly in high-volume urban centres. In the drug-abusing population, mycotic arterial pseudoaneurysms most often occur because of missed venous injection and are typically seen in the groin, axilla, and antecubital fossa. Mycotic aneurysms may lead to life-threatening haemorrhage, limb loss, sepsis, and even death. Any soft-tissue swelling in the vicinity of a major artery in an intravenous drug abuser should be suspected of being a false aneurysm until proven otherwise and should prompt immediate referral to a vascular surgeon for investigation and management. We report a case of rupturing mycotic pseudoaneurysm of the left common femoral artery treated by surgical resection followed by vessel reconstruction with autologous material. Unfortunately, at the time of discharge a sudden leakage from the vein graft anastomosis occurred, with subsequent massive bleeding, and required emergent endovascular covered stenting. To the best of our knowledge, this is the first reported case of femoral artery bleeding in a drug abuser treated by stent graft placement.

Type B aortic dissection is an uncommon yet potentially catastrophic clinical event that mandates prompt recognition and expeditious treatment. Patient survival depends on early and accurate diagnosis and prompt medical or surgical treatment. Unfortunately, when type B aortic dissection is associated with end-organ ischemia, medical treatment may not prove beneficial, with patients addressed to surgery; recently, either percutaneous fenestration or primary endovascular aortic repair has been proposed as a valuable alternative to surgery in this scenario. Although the ideal endograft has not emerged and improvement in the long-term behavior of the devices is required, endograft placement is becoming the first choice in patients with complicated type B aortic dissection requiring emergency treatment.
