Objective: To analysis the factors related to the complications of vascular surgeries in a general hospital.
Methods: A single-center and prospective study was organized from January, 2012 to December, 2012 in Peking Union Medical College Hospital. Patients who underwent selective primary vascular procedures were included in the study.
Results: Totally 826 consecutive cases who met the inclusive criteria were recruited, with 566 males (68.5%) and an average age of (59 ± 14) (13-89) years old. There were 38 patients (4.6%) suffering complications after the procedures, including 2 deaths (0.2%) during hospitalization. The complication rates were significantly higher in the patients with hypertension, cardiac disease, history of cerebral strokes, renal function insufficiency or diabetic mellitus (P < 0.05). The complication rates were significantly higher in group with high grade of ASA (ASA class 3 and 4) or in group underwent high grade of vascular surgeries (Class 3 and 4) , comparing with group with low grade of ASA (ASA class 1 and 2) (relative risk ratio, RR = 2.579; 95%CI: 1.333-4.993; P < 0.01) , or with group underwent low grade of vascular surgeries (Class 1 and 2) (RR = 4.268; 95%CI: 2.197-8.293; P < 0.01).
Conclusions: Hypertension, cardiac disease, history of cerebral stroke, renal function insufficiency or diabetic mellitus are risk factors related to complications of vascular surgeries. The patients with high grade of ASA or underwent high grade of vascular surgeries may have significant higher risks of complications after the procedures.
