Assessment of predictive factors for acute kidney injury after thrombectomy using AngioJet for iliofemoral deep vein thrombosis.

Abstract

Objective: To identify the relationship between acute kidney injury (AKI) and the treatment of iliofemoral deep vein thrombosis in the acute phase using an AngioJet® device.

Methods: This retrospective study included all 40 patients diagnosed with iliofemoral deep vein thrombosis who underwent treatment with AngioJet, conducted at the Vascular and Endovascular Clinic Service (Team Science) of Hospital Israelita Albert Einstein(HIAE), Hospital Edmundo Vasconcelos, Hospital São Camilo.

Results: No significance difference was observed regarding sex (p=0.128), procedures with vs. without stent placement (p=0.138), body mass index (BMI) <25 vs. >25kg/m2 (p=0.4), and BMI <30 vs. >30kg/m2 (p=0.77). Independent factors associated with the development of AKI included hemoglobin <10mg/dL in the immediate postoperative period (p=0.0009), a 2-point decrease in hemoglobin level immediately after surgery (p=0.0088), history of previous major surgery (p=0.002), and glomerular filtration rate <60mL/min/1.73m² (p=0.02) in the first postoperative day.

Conclusion: A relationship between the use of AngioJet and the development of AKI was noted. Independent risk factors for AKI were hemoglobin <10mg/dL in the immediate postoperative period, a 2-point decrease in hemoglobin level immediately after surgery, history of previous major surgery, and glomerular filtration rate <60mL/min/1.73m² in the first postoperative day.
