BACKGROUND: Complications after open vascular surgery are a major health challenge for the healthcare system and the patients. Infrainguinal vascular surgery is often perceived as less risky than aortic surgery and the aim of this study was to identify which risk factors correlated with postoperative complications after open vascular surgery for infrainguinal occlusive disease in an 8-year cohort using the Danish National Vascular Registry (Karbase), which gathers information on all vascular procedures in Denmark.

METHODS: This study is a retrospective cohort study. The Karbase was searched for the predefined procedures from January 1, 2005 through December 31, 2012 at our 2 vascular departments. Both elective and urgent surgeries were included. Complications were defined as wound, surgical, or general complication according to Karbase.

RESULTS: Three thousand two hundred two procedures were identified. Median age was 70 years and 21% were octogenarians. Sixty percent were male. There was an overall complication rate of 30%, with 19% being wound complications, 6% surgical, and 10% general complications. The greatest risk factors for developing a complication were high age, cardiac and renal disease, high American Society of Anesthesiologists score, and general anesthetics. The 30-day mortality was 5% (1% for claudicants and 8% for acute ischemia) and the 30-day amputation rate was 7% (0.5% for claudicants and 21% for gangrene).

CONCLUSIONS: There is a high risk of complication in peripheral vascular surgery. Risk factors are modifiable or nonmodifiable. It is important to identify the risk factors and treat and optimize the patient cardiac and renal status before surgery if time allows, and also to perform surgery in local or regional anesthesia whenever possible, to reduce the risk of postoperative complications.
