Key result
Advanced abdominal aortic calcification is linked to ~7.5-fold higher mortality after lumbar disc surgery.
Why the study?
The effect of abdominal aortic calcification on mortality after lumbar degenerative disc surgery and its role as a predictor of survival was unclear.

Absolute Event Rate: 32.9% vs 4.4%

Advanced calcification was associated with higher mortality after lumbar surgery; hypothesis-generating and should not yet change preoperative risk assessment.
Objective: The aim of this study was to show the effect of the presence of AAC on mortality after lumbar degenerative disc surgery and to determine whether it is a predictor of survival. Methods: Between 2014 and 2016, abdominal aortic calcifications were recorded by grade in patients who underwent surgery for degenerative lumbar disc herniation and therefore underwent updated lumbar CT. In addition to the demographic data of these patients, ASA scores were also recorded and these scores were statistically compared. Results: The age of the patients in the Advanced Calcification group was significantly (p < 0.05) higher than that in the Mild Calcification group. The ASA score in the Advanced Calcification group was significantly (p < 0.05) higher than the Mild Calcification group. . Ex rate in the Advanced Calcification group was significantly (p < 0.05) higher than the Mild Calcification group. Conclusion: There is a strong correlation between the degree of abdominal aortic calcifications and patient survival. This relationship is thought to be an important guiding scoring for spinal surgeons in the preoperative preparation phase.

Tufan et al. (2023) conducted a cohort in Lumbar degenerative disc disease (n=245). Advanced abdominal aortic calcification vs. Mild abdominal aortic calcification was evaluated on Mortality rate (p=<0.05). Patients with advanced abdominal aortic calcification undergoing lumbar degenerative disc surgery had a significantly higher mortality rate compared to those with mild calcification (32.9% vs. 4.4%).
