Embolization of Pulmonary Catheter-Induced Pulmonary Artery Pseudoaneurysms

Pulmonary Artery Rupture Induced by a Pulmonary Artery Catheter: A Case Report and Review of the Literature

“…Embolization was successful in producing immediate occlusion of the pseudoaneurysm in all 6 cases in one report, with no recurrence of hemoptysis during a mean followup of 19 months [37]. As expected when using contrast agents during angiography, some degree of acute renal insufficiency occurred [37]. Among other complications, minor pulmonary infarctions were common following coil embolization but usually did not significantly affect the patient's clinical status or arterial blood gases [39,40].…”

“…Embolization can be performed with various agents such as steel coils placed in or adjacent to the pseudoaneurysm [34,35], liquids (sobutyl-2-cyanoacrylate) [36], absorbable gelatin sponges [37], or detachable balloons [38]. Embolization was successful in producing immediate occlusion of the pseudoaneurysm in all 6 cases in one report, with no recurrence of hemoptysis during a mean followup of 19 months [37].

Pulmonary artery pseudoaneurysm after Swan-Ganz catheterization: a case presentation and review of literature

“…5 Ray and colleagues reported a patient who developed contrast-induced nephrotoxicity and another patient with steep creatinine rise after the procedure with accompanying multiorgan failure. 6 Both patients died during the course of the index hospitalization from cardiogenic shock. 6 Only one patient in the reviewed population underwent surgery without prior transcatheter treatment.…”

“…6 Both patients died during the course of the index hospitalization from cardiogenic shock. 6 Only one patient in the reviewed population underwent surgery without prior transcatheter treatment. She had an infiltrate on the CXR that was performed immediately after a mitral valve replacement during which a Swan-Ganz catheter was inserted.…”

Gelfoam embolization of a distal coronary artery guidewire perforation

“…Transcatheter embolization with Gelfoam is an effective method for controlling hemorrhage in various organs [24] and for hepatic artery embolization in patients with primary and metastatic liver tumors [25,26]. The use of Gelfoam to treat catheter-induced pulmonary artery pseudoaneurysms and ureteric and broncho-esophageal fistulae has also been described [27][28][29].…”
