We report two cases of Sneedon’s syndrome. Both cases had widespread livedo reticularis with repeated cerebrovascular accidents without persistent neurological deficit. In one case, hemostatic examination revealed an imbalance of plas-minogen activator-inhibitor values, possibly related to the thrombogenic propensity of the syndrome. Treatment with acetylsalicylic acid led to normalization of hemostatic parameters and resulted in a symptom-free period of more than 10 months. The importance of hemostatic screening in patients with Sneddon’s syndrome is discussed.
Purpose:
To assess the safety and efficacy of main splenic artery embolization. To assess the potential difference post-embolization of the residual splenic volume in patients embolized for trauma versus those embolized for (pseudo)aneurysms.
Materials and Methods:
A retrospective analysis was performed on a cohort of 65 patients (36 males) who underwent pre- and post-embolization computed tomography. Patients’ demographics, pre- and post-interventional medical and radiological data were gathered. Splenic volume calculations were semi-automatically performed via a workstation. Patients with splenic aneurysms or pseudoaneurysms of the main splenic artery (group 1) were compared to those with splenic rupture (group 2) using Wilcoxon rank tests.
Results:
The main indications for splenic artery embolization were splenic rupture (n = 22; 34%) and splenic pseudoaneurysm (n = 19; 29%). The technical success rate was n = 63; 97%. The procedure-related complication rate was n = 7; 11%, including abscess formation (n = 5; 8%), re-bleeding (n = 1; 1.5 %) and pseudoaneurysm re-opening (n = 1; 1.5%). The overall 30-day mortality was n = 7; 11%.
Median follow-up for groups 1 and 2 was 1163 days (61–3946 days) and 702 days (43–2095 days) respectively. When processable (n = 23), the splenic volume in group 1 (n = 7) was 311 cm
3
and 257 cm
3
(p = 0.1591) before and after embolization respectively, and in group 2 (n = 16) it was 261 cm
3
and 215 cm
3
(p = 0.4688), respectively.
Conclusions:
Main splenic artery embolization is efficacious, with low procedure-related complication and 30-day mortality rates. No significant differences in residual post-embolization splenic volume were found between patients treated for splenic rupture versus those treated for splenic arterial (pseudo)aneurysm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
