Objective To observe the pocket complications after permanent pacemaker implantation and to analyze the reasons and treatment strategies. Methods Pocket complications in 1368 cases of bradyarrhythmia or tachyarrhythmia in past 26 years were summarized. Results Of the 1368 cases, there were 80 cases of pocket hematoma (5.8%), among which, 27 cases underwent blood aspirate or surgical incision. Incidence of pocket hematoma was related to factors such as age, poor nutrition, preoperative use of anticoagulant drugs, low platelet count, and incorrect anatomical hierarchy or careless manipulation during the operation. The pacemaker type and weight had no influence on its occurence. Timely discovery, longer compression time and necessary blood aspirate usually worked, and sometimes surgical incision was needed. There were 6 cases (0.4%) of pocket ulceration, which was related to factors such as large pacemaker, mismatch between the pocket and the pacemaker in depth, location and size, abundant leads and wires above the pacemaker, and occasional rejection reaction. There were 3 cases of pocket infection (0.2%), which considered as secondary infection after pocket ulceration. Pocket translocation following thorough debridement, combined with general antibiotics application and nutrition improvement was effective. Electrode removal was required to thoroughly deal with the infection. Conclusions Pocket complications are associated with the patients￠ constitution. Inadequate preoperative preparation, careless manipulation and inappropriate postoperative treatment are also the risk factors. Incidence of pocket complications can be reduced by careful pre-operation preparation, standard manipulation, timely discovery and appropriate treatment.
