Vasculitis & polymyalgia rheumatica
Venous vessel-wall assessment with superb microvascular imaging in Behçet syndrome
Authors' conclusion
Evaluation of the vessel wall with SMI in BS may be a promising approach for showing inflammation as an inexpensive, non-invasive and reliable imaging method that does not require a contrast agent.
Study context
- Population
- Patients with Behçet syndrome (BS) and non-BS patients with red palpable lesions on physical examination; B-mode US, CDUS, PDUS and superb microvascular imaging (SMI)
- Participants
- 51 vs 31
- Exposure
- BS vs non-BS patients with red palpable lesions
- BSn = 51
- non-BSn = 31reference
- Outcome
- Vessel-wall signal by SMI in STM lesions (diagnosed by CDUS)
Methodological detailsimaging assessed by the same radiologist, images evaluated independently by another radiologist
- Imaging assessed by the same radiologist, images evaluated independently by another radiologist
Main finding
As reported in the abstract
Vessel-wall signals on SMI in STM lesions
Observational data: associations, not effects.
Further findings
| Outcome | BS | non-BS |
|---|---|---|
| At least grade 2 vessel-wall signal on SMI among those with signal (STM) | 76% | 1 events |
- At least grade 2 vessel-wall signal on SMI among those with signal (superficial thrombophlebitis (STM)): 16 of 21 BS; 1 of 3 non-BS
Vessel-wall signal on SMI in erythema nodosum (EN) lesions (diagnosed by CDUS: 25 BS, 11 non-BS)
- SMI showed no vessel-wall signal in these patients
