Abstract:
Objective:To evaluate the efficacy of super-selective renal artery embolization (SRAE) in the treatment of patients with traumatic renal hemorrhage who failed to respond to conservative treatment.Methods:A total of 64 patients with traumatic renal hemorrhage admitted to Wenling First People′s Hospital from May 2018 to May 2020 were selected as the study subjects. All patients were treated with SRAE, the clinical efficacy, angiographic performance, renal function, complications, postoperative blood transfusion rate and renal retention rate of the patients were observed.Results:There were 62 cases among 64 cases with traumatic renal hemorrhage were successfully embolized once, with a success rate of 96.88%(62/64). By angiography, 46.88%(30/64) of the patients had pseudoaneurysms, 29.69% (19/64) had renal arteriovenous fistula, 9.38% (6/64) had pseudoaneurysms complicated with renal arteriovenous fistula and 14.06% (9/64) had contrast extravasation. Bleeding points were observed in all patients, and the proportions of 1 bleeding point, 2 bleeding points and 3 bleeding points were 73.44%(47/64), 20.31% (13/64) and 6.25% (4/64), respectively. The proportions of upper, middle and lower bleeding points were 18.75% (12/64), 37.50% (24/64) and 43.75% (28/64). On the 7th day after the surgery, the levels of hemoglobin (Hb) and haematocrit (Hct) were higher than those before surgery: (91.79 ± 23.58) g/L vs. (90.45 ± 22.31) g/L, 0.272 ± 0.070 vs. 0.262 ± 0.068; the level of serum creatinine (SCr) was lower than that before surgery: (82.97 ± 25.32) μmol/L vs. (84.57 ± 24.51) μmol/L, the differences were statistically significant ( P<0.05). The total incidence of postoperative complications was 26.56% (17/64). The renal retention rate was 100.00% (64/64) and the proportion of blood transfusion patients was 39.06% (25/64). Conclusions:SRAE can play a good hemostatic effect in patients with traumatic renal hemorrhage that failed to respond to conservative treatment. It is safe and reliable with a low incidence of complications, and can better protect renal tissue function.
