Objective: Vascular Ehlers-Danlos syndrome (VEDS) is rare and associated with arteriopathies. The aim of this study is to investigate the presentation, operative interventions, and outcomes of splenic arterial pathology in a population of more than 1500 individuals with genetically confirmed VEDS due to pathogenic COL3A1 variants.
Methods: Cross-sectional analysis of 1547 individuals was performed. The data were assembled by harmonizing data from three overlapping cohorts with genetically confirmed VEDS: the VEDS Collaborative Natural History Study (N = 242), a single-center cohort (N = 75), and the University of Washington Collagen Diagnostic Lab cohort (N = 1231). Duplicates were identified and removed. Patients were selected for analysis if they had splenic artery aneurysm (SAA), pseudoaneurysm, dissection, thrombosis, or rupture. Demographics, COL3A1 variants, interventions, and outcomes were analyzed. Comparisons by splenic artery rupture were made.
Results: A total of 88 patients presented between 1992 and 2021 with splenic artery pathology (5.7% of the cohort; mean age at diagnosis, 37 ± 11.1 years; 50% male). One-third were diagnosed with VEDS prior to the splenic artery pathology diagnosis, and 17% were diagnosed post-mortem. Most had a positive family history (61%). Most had COL3A1 variants associated with minimal normal collagen production (71.6%). Median follow up was 8.5 years (interquartile range, 0.9-14.7 years). Initial presentation was rupture in 47% of the cases. Splenic artery rupture overall was 51% (n = 45), including four cases of splenic rupture. There were no major differences in VEDS-related manifestations or COL3A1 variant type by rupture status. SAA was noted in 39% of the cases. Only 12 patients had splenic artery diameter documented in 12 cases with a median diameter of 12 mm (interquartile range, 10.3-19.3 mm). A total of 34 patients (38.6%) underwent 40 splenic arterial interventions: 21 open surgical, 18 embolization, and one unknown procedure. More than one splenic artery intervention was performed in five cases (14.7%). Open repair complications included arteriovenous fistula (n = 1), intestinal or pancreatic injury (n = 1 each), and four intraoperative deaths. There were no deaths or access site complications related to splenic artery embolization. Four patients (23.5%) developed a new SAA in the remaining splenic artery post embolization. All-cause mortality was 35% (n = 31), including 22 related to a ruptured splenic artery.
Conclusions: Splenic arteriopathy in VEDS is associated with variants that affect the structure and secretion of type III collagen and frequently present with rupture. Rupture and open repair are associated with high morbidity and mortality, whereas embolization is associated with favorable outcomes. Suggest repair considerations at SAA diameter of 15 mm. Long-term follow-up is indicated as secondary splenic arteriopathy can occur.
