[Necrosis of the pouch due to nontraumatic rupture of the pile during permanent endocardial electrostimulation].
Necrosis of the pouch containing the generator, due to non-traumatic breakage of the batteries, was observed in a patient with a permanent pacemaker, followed by rapid ingravescence. The cause of this complication is discussed. Chemical inflammation was noted soon after the pacemaker ceased to function. Initially this was similar to the not uncommon bacterial inflammation noted in such patients. Here, of course, the pacemaker usually continues to work, and its replacement is optional, whereas in the reported case is an emergency matter. In situations where tissue distress in the pouch is accompanied by inflammation, therefore, thought should be given to the possibility that, even if the batteries are still working, the cause may be chemical or electrochemical rather than septic, and than sudden breakdown of the generator may be expected.
