Objective To summarize the clinical morphological classification feature of symptomatic spontaneous isolated celiac artery dissection (SICAD), basing on the relative diameter of the true lumen (TLRD) and type of lesion, and then summarize the reasonable clinical treatment strategies and timing of arterial reconstruction.Methods Retrospectively analyzed the imaging data, treatment methods, perioperative complication, and follow-up results of 26 symptomatic SICAD patients admitted to the Department of Endovascular Surgery of The First Affiliated Hospital of Zhengzhou University from May 2012 to May 2019, patients were divided into conservative treatment group (n=12) and endovascular intervention group (n=14) according the treatment, and then compared the clinical data of the two groups.Results Twelve patients in the conservative treatment group had an average of 12.6 days (5–22 days) and discharged from hospital with better condition, of which 11 patients’ TLRD≥30%. In the endovascular intervention group, 2 patients continued to aggravate the symptoms at the 3rd day of admission and received endovascular intervention, the remaining 12 patients’ symptoms were not significantly relieved or the symptoms reappeared after averaged 11.4 days, whose TLRD<30% or diameter >1.5 cm. Compared with the endovascular intervention group, the duration of symptoms was shorter (P=0.04), proportions of back pain (P=0.02) and chest pain (P=0.04) were lower, TLRD value and proportion of TLRD value>30% (subtype of a) were higher (P=0.01, P=0.02). The average follow-up duration of 26 patients was 28.2 months (12–83 months). The follow-up results of all patients in the conservative treatment group were good and no relevant symptoms had appeared since discharge. One patient in the endovascular intervention group had transient liver function damage, 1 patient had severe deformation of the proximal end of the stent at 1 year after implantation of the celiac artery (CA) stent. The remaining patients were stable with no progress.Conclusions For symptomatic SICAD, if the clinical symptoms are stable after hospitalization, conservative medication and close imaging follow-up are preferred, if there is no relief of symptoms, continuous organ perfusion and other manifestations based on medication, endovascular intervention can be considered for arterial reconstruction, the early and medium follow-up results were satisfactory under this treatment algorithm. In addition, there are differences in TLRD value between the conservative treatment group and the endovascular intervention group, suggesting that TLRD as the morphological characteristics of the classification has a potential guiding significance for the development of clinical treatment strategy.
