Wedging the Pulmonary Artery Catheter: Changes in Left Atrial and Pulmonary Artery Pressures and Risk for Perforation

Pulmonary artery rupture as a complication of Swan-Ganz catheter application. Diagnosis and endovascular treatment: a single centre's experience

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.

Endovascular treatment of PA pseudoaneurysm caused by Swan-Ganz catheter

The following case report describes a complication of Swan-Ganz catheterization and its endovascular treatment with a single coil. Application of this particular catheter in the pulmonary artery during cardiac surgery may lead to mechanical perforation and creation of an extravascular sac, which is called a pseudoaneurysm. There are different methods that lead to tamponade or closure of the leakage. Interventional cardiology procedures are nowadays the most appropriate way of treatment of Swan-Ganz catheter induced vascular complications.
