Procedure coded as 36299, 76499, 37204, 75894, not sure if this is correct. Physician not clear as to where in the neck the patient was accessed. Thanks! Indication: Right neck venous malformation Procedure: Right neck venous malformation embolization Findings: After obtaining informed consent, the right neck was prepped and draped in normal sterile fashion. Sedation was provided by the anesthesiology service in the form of general endotracheal anesthetic. Sonographic guidance was used to direct needle access to a vascular structure within the malformation. Contrast material was injected for malformation venography. There is a complex vascular structure with what appears to be irregular venous as well as lymphatic component. Via this access, a total of 4 cc of 3% STS was foamed and administered in 3 separate sessions with interval dwell time for the purpose of malformation venous scleroablation. Needle access was removed. A compressive dressing was placed. The patient tolerated this should well and left the department in stable condition. Impression: 1. Right neck vascular malformation venography demonstrates a complex venolymphatic lesion 2. Technically successful scleroablation of the lesion utilizing foamed STS with excellent result
