Iatrogenic combined common iliac and lateral sacral artery perforation during coronary angiography: A case report and review of literature.

One of the rare but lethal complications of femoral artery catheterization for coronary angiography is arterial rupture, which can cause a range of negligible to massive retroperitoneal hemorrhage. This case presents a woman with unstable angina who underwent coronary catheterization. After arterial sheath placement, extravasation of blood from the right common iliac and lateral sacral arteries was seen, a diagnosis that has been reported rarely before. The bleeding was controlled with balloon inflation in the lateral sacral artery and a stent graft implantation in the right common iliac artery. The patient remained asymptomatic during the procedure and the short- and long-term follow-up. Interventional cardiologists and radiologists who access the femoral artery for any procedure should be aware of this possible event. Sometimes, this situation manifests with nonspecific symptoms such as weakness, lethargy, and pallor. Moreover, more logistical preparation and training are needed to overcome these unexpected conditions.
