Pituitrin use is associated with an increased risk of inguinal hematomas and pseudoaneurysms in patients undergoing femoral artery puncture.

Objective: Femoral artery puncture (FAP) is an effective method for interventional percutaneous vascular procedures. However, FAP leads to complications including hematomas and pseudoaneurysms. This study was performed to determine whether pituitrin infusion or vascular closure devices (VCDs) increase the risk of complications after FAP.

Methods: This single-center retrospective study included 3641 patients who underwent FAP. The patients were divided into two groups: a groin complication group (including hematomas and pseudoaneurysms) and a no-groin complication group.

Results: In the multivariate analysis, perioperative pituitrin infusion and the use of VCDs were strongly associated with inguinal hematomas and pseudoaneurysms. The complication rate was obviously higher in patients who underwent bronchial artery embolization (BAE). Because high dosages of pituitrin and VCDs were used in patients undergoing BAE, postoperative hematoma development occurred significantly earlier in these patients. Hematomas occurred within 14 days of the operation in all patients who underwent BAE.

Conclusion: Perioperative pituitrin infusion and the use of VCDs are associated with an increased risk of complications after FAP, including hematomas and pseudoaneurysms. Notably, patients who underwent BAE, who are subject to higher pituitrin and VCD use, showed a higher complication rate. The incidence of complications was highest within 2 weeks postoperatively.
