Point-of-Care Ultrasound (POCUS) for Precision Management in Ellanse-Treated Patients.

backgroundInnovative use of a point-of-care ultrasound (POCUS) device facilitates the diagnosis and management of potential challenges associated with Ellanse treatment. Our case series of 6 patients illustrates the effectiveness of POCUS in managing challenges associated with Ellanse treatment. Ultrasound analysis is performed in all 6 patients, and management decisions are guided by ultrasound findings.

methodOur case series of 6 patients (A, B, C, D, E & F) consists of Ellanse-treated patients. They presented problems associated with (1) facial overfilling, (2) diagnostic challenges, (3) underfilling requiring POCUS-guided treatment, (4) confirmation of nodule dissolution, and (5) pretreatment vascular assessment.

resultsPatients A and B presented with complaints of facial overfilling, and ultrasound analysis attributed the overfilling to previous autologous fat grafting and hyaluronic acid filler treatments respectively. Patient C complained of facial cheekbone prominence after receiving 26 mL of Ellanse in her entire face over 3 years. The patient was reassured that her cheek prominence was secondary to neocollagenesis following ultrasound analysis and refused further intervention. Patient D had successful dissolution of a nodule associated with Ellanse, and this was confirmed with photographs and POCUS imaging. Patient E had underdevelopment of collagen in the left midcheek following initial Ellanse treatment 3 months ago. 0.2 mL of additional Ellanse was injected with a 25G cannula under POCUS guidance to the left cheek with satisfactory correction. Patient F had three previous sessions of Ellanse treatments. She underwent vascular anatomy analysis with an ultrasound Doppler mode prior to the fourth Ellanse treatment. The presence of dense neocollagenesis following Ellanse can alter vascular patterns. A preprocedural analysis is recommended in planning subsequent treatment.

conclusionOur limited case series of 6 patients provides useful insights into the effectiveness of POCUS as the initial imaging modality of choice when managing Ellanse-treated patients. POCUS imaging provides valuable diagnostic information (Patient A, B, C and D) and therapeutic purposes such as POCUS guided injection and pretreatment assessment (Patient D and E). POCUS can be the initial imaging modality of choice as it is convenient and allows clinical management to be made based on imaging findings.
