“…Rupture of the pulmonary artery is generally viewed as the most serious complication associated with use of balloon-tipped pulmonary arterial catheters. To our knowledge, 29 cases have been reported in the literature between 1971 and 1982 (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). Forty-five percent of these were fatal.…”

of rupture of the pulmonary artery by pulmonary artery balloon-tipped catheters. Anesth Analg 1983;62:925-30. High pressures have been reported in pulmonary artery catheter balloons. This study was undertaken to determine the in vitro rupturing pressures of human peripheral pulmonary arteries and to evaluate whether such pressures could be generated under clinical conditions. The in vitro model then was confirmed in vivo in the dog and the evolution of a rupture of a peripheral pulmonary artery studied. In vitro, pulmonary arteries of subjects under age 60 yr are remarkably resistant and tolerate intra-balloon pressures of 2700 mm Hg in the one mid-pulmonary artery studied and up to 4219 k 720 mm Hg (mean 5 SD) in the distal pulmonary artery. Subjects over the age of 60 yr have significantly lower rupturing pressures (1965 * 540 mm Hg in the mid-pulmonary artery, and 2498 2 600 mrn Hg in the distal pulmonary artery), (P < 0.05). Thus overdistension by the balloon may explain most ruptures. Preexisting pulmonary hypertension did not affect in vitro rupturing pressures. Clinicians generated intraballoon mean pressures of 795 ? 130 mm Hg, with 20% of them generating higher and potentially dangerous pressures (1000 mm Hgor more). The in vitro model was confirmed by in vivo studies in dogs with pressures that cause pulmonary artery rupture. Furthermore, in normal dogs, rupture of a peripheral pulmonary artery was without complications. This suggests that rupture of the peripheral pulmonary artery may occur clinically more frequently than reported. The user of flotation pulmonary arterial catheters should be aware of the dangers associated with this diagnostic tool. In particular, liquids must never be used to inflate pulmonary arterial catheter balloons.

“…In the previously described cases pulmonary hypertension was moderately severe in one case (Golden et al, 1973) and mild in another (Lapin and Murray, 1972). In neither was it correlated per se with the occurrence of the perforation of the pulmonary artery.…”

“…Although five previous cases of pulmonary artery perforation have been reported (Chun and Ellestad, 1971;Lapin et al, 1972;German et al, 1973;Golden et al, 1973;Page et al, 1974), the factors involved in these perforations by balloontipped catheters are unclear. Several predisposing factors have been emphasised; pulmonary hypertension (German et al, 1973), an excessively peripheral location of the catheter (Chun and Ellestad, 1971), a large loop of catheter in the right atrium or right ventricle which may allow the tip to perforate the pulmonary wall secondary to catheter motion (Chun and Ellestad, 1971), and anticoagulation (Golden et al, 1973).…”

“…Swan and Ganz in their original paper (Swan et al, 1970) recommended that the balloon be deflated in the wedge position, advanced 1-3 cm, and then reinflated each time the wedge pressure measurement was required. In contrast to this, Lapin and Murray (1972) suggested that when the balloon is inflated in the wedge position it creates a pressure gradient across the pulmonary artery wall that may lead to perforation. They recommended inflating the balloon in place each time a wedge pressure recording is needed.…”

“…The common complications associated with their insertion are usually not severe and have not been associated with lethal consequences (Foote et al, 1974;Katz et al, 1977). Major complications have been described, among which are five cases of pulmonary artery perforation, two of them fatal (Chun and Ellestad, 1971;Lapin and Murray, 1972;German et al, 1973;Golden et al, 1973;Page et al, 1974).…”
