Nominal Hemoptysis Heralds Pseudoaneurysm Induced by a Pulmonary Artery Catheter

Swan-Ganz Catheter-Induced Pulmonary Artery Pseudoaneurysm Formation

“…Despite this single reference, most authors emphasize the importance of prompt treatment of the pseudoaneurysm once the diagnosis is established. In fact, Yellin and colleagues 13 recommend that all survivors of an initial episode of hemoptysis associated with PA catheter manipulation undergo emergent contrast-enhanced spiral CT scanning or angiography of the chest for diagnosis and possible treatment.…”

“…4 -12 Of these, PA rupture is the most serious complication, with a reported mortality rate as high as 50%. [13][14][15] We present three cases of PA rupture with pseudoaneurysm formation, all of which were successfully treated percutaneously with coil embolization, that occurred over a 6-month period. A review of the literature also is presented.…”

“…But, should undetected damage to the balloon be the reason for failure to obtain this clear PA pressure trace, refloating of the same catheter will put a patient at risk [2][3][4] Also, in case of a definite mitral regurgitation or high PA pressures, it may be impossible to get a wedge pressure tracing at all [5].

“…PAAs and PAPs can result from congenital defects in the vessel wall or from acquired causes, such as trauma, infection, or iatrogenic causes following injury from catheterizations . The gravest complication occurs with aneurysmal rupture that can result in extensive hemorrhage and asphyxiation carrying a mortality of 45–64% . Pseudoaneurysms possess a higher risk of rupture .…”

“…[1][2][3][4] The gravest complication occurs with aneurysmal rupture that can result in extensive hemorrhage and asphyxiation carrying a mortality of 45-64%. 5 Pseudoaneurysms possess a higher risk of rupture. 4 Management and treatment of PAAs has been historically challenging; initially limited to open surgical repairs, however, as endovascular technology has advanced, percutaneous approaches may present alternative options.…”
