08:28: Effect of Neck Dissection on Quality of Life after Chemo‐XRT

Abstract

Macrocyst (Ͼ1cm) access performed with coaxial 5F catheter system and treated with dual-drug chemoablation (sequential intracystic sodium tetradecyl sulfate and ethanol); doxycycline used for microcyts. Macrocysts and microcysts were treated after complete cyst aspiration with sonographic guidance. Macrocyst containment was confirmed with fluoroscopic cystography. Catheter drainage for macrocystic treatment was maintained for three days following treatment. Fifty-four macrocysts and 40 microcysts were treated; goals of treatment are complete cyst ablation documented by sonography, CT, or MR imaging, and excellent cosmetic results. RESULTS: Mean number of treatments ϭ 1.7 per patient; mean number of treatments for macrocysts ϭ 1.1; mean treatments for microcysts ϭ 2.1 (macrocysts and microcysts most often treated as separate sessions). Treatment efficacy 54/54: macrocysts ablated (100%); microcyst controlled 17/17 pts; follow-up 2-60 mo. Treatments included massive cervical cysts and cysts surrounding the facial nerve and brachial plexus. Complications: infection in 2/31 patients; no postprocedural pain or other complications. CONCLUSIONS: Percutaneous interventional radiological regimens provide effective treatment, with rapid resolution, for macrocystic and microcystic LM as primary treatment, or for recurrence following surgical resection, without serious complications or deformity.
