Abstract

Background:

Patients with Cushing syndrome (CS) have an increased risk for venous thromboembolism (VTE). However, it is unclear whether patients undergoing adrenalectomy for CS are at increased risk for postoperative VTE. The aim of this study was to determine the rate of postoperative VTE in patients undergoing adrenalectomy for CS.

Methods:

A retrospective analysis of patients in the American College of Surgeons National Surgical Quality Improvement Program database who underwent adrenalectomy from 2005 to 2016 was performed. We compared the clinical characteristics and 30-day postoperative VTE occurrence in patients with and without CS.

Results:

A total of 4217 patients were analyzed; 2607 (61.8%) were female and 310 (7.4%) had CS. The overall prevalence of postoperative VTE was 1.0% (n = 45). The rates of VTE were higher in patients with CS (2.6% vs 0.9%; P = 0.007). In the two groups, CS was associated with younger age, increased body mass index, and diabetes mellitus (P < 0.001). CS was also associated with longer length of operation and longer hospital length of stay (P < 0.001). In the subgroup of patients who had diagnosed VTE, CS was associated with longer length of operation (P < 0.001). Rates of laparoscopic vs open surgery were equivalent between patients with and without CS, and VTE events did not differ. The median time to VTE event was 14.5 days (range, 1 to 23 days) in the CS group and 4 days (range, 2 to 25 days) in the group without CS.

Conclusions:

The prevalence of postoperative VTE was increased in patients undergoing adrenalectomy for CS. In patients with CS undergoing adrenalectomy, VTE prophylaxis for 28 days should be considered upon discharge.
