Introduction: The placement of a Swan-Ganz catheter into the pulmonary artery may lead to a number of complications (2-17%). In less than 0.2% of cases Swan-Ganz catheterization results in serious vascular damage - pulmonary artery rupture (PAR). This paper presents two distinct forms of iatrogenic PAR treated endovascularly using different vascular devices.
Aim: To evaluate the effectiveness of endovascular treatment and the application of different types of vascular devices in the management of pulmonary artery rupture caused by Swan-Ganz catheterization.
Material and methods: In this retrospective study we evaluated 2 patients in whom Swan-Ganz catheter application was used for perioperative monitoring and resulted in pulmonary artery rupture. This complication was treated endovascularly by means of interventional cardiology.
Results: We report the cases of 2 patients with a pulmonary artery pseudoaneurysm formed in the perioperative period. In case 1, a single, 4-loop, 3 mm diameter coil was implanted. In case 2, a 5 mm Amplatzer Vascular Plug IV was applied. In both cases, the endovascular approach resulted in total occlusion of the feeding artery and reduced further extravasation of the blood.
Conclusions: Despite its extremely low incidence, iatrogenic PAR is a serious, life-threatening complication of Swan-Ganz catheterization that requires urgent attention. Among available methods of treatment, percutaneous embolization is a relatively quick, safe, accurate and highly effective alternative to traumatizing surgery.
