Evolving Experience With Direct Puncture Therapeutic Embolization for Adjunctive and Palliative Management of Head and Neck Hypervascular Neoplasms

Abstract

Our results lend further support to the safety and efficacy of DPTE in the management of hypervascular neoplasms of the head and neck. With our increasing experience, this technique is evolving into a primary therapeutic modality for optimal tumor devascularization.

Usefulness of Percutaneously Injected Ethylene-Vinyl Alcohol Copolymer in Conjunction with Standard Endovascular Embolization Techniques for Preoperative Devascularization of Hypervascular Head and Neck Tumors: Technique, Initial Experience, and Correlation with Surgical Observations

“…13 A percutaneous approach by using liquid embolic material such as cyanoacrylate glue has been shown to be safe and effective in obliterating the vasculature in a number of different hypervascular head and neck lesions. Chaloupka et al 14 performed percutaneous injection of a cyanoacrylate mixture in 24 cases achieving either total or near-total devascularization in 83% of the cases with no serious complications. Abud et al 15 demonstrated that DPE could be performed in head and neck paragangliomas utilizing modified acrylic glue with a high degree of effectiveness, technical success, and a low rate of complications.…”

Guidelines for the use of NBCA in vascular embolization devised by the Committee of Practice Guidelines of the Japanese Society of Interventional Radiology (CGJSIR), 2012 edition

“…In cancer patients, NBCA is indicated for tumor bleeding [72] and can also be used to achieve a palliative therapeutic effect by improving the tumor response [32,41,142,145,176]. In addition, NBCA has been indicated for arterial redistribution and hepatic arterial catheter fixation during hepatic arterial infusion chemotherapy [68,159,180,181].…”

Laryngeal Paraganglioma: A Rare Clinical Entity Managed by Supraselective Embolization and Lateral Pharygotomy

“…Sonography guided or CT guided intratumoral injection of a liquid adhesive like N-butyl-2-cyanoacrylate gives better devascularization compared to transarterial embolization and is a safe and effective method of preoperative embolization [11][12][13][14]. Percutaneous direct embolization provides an easy access to hypervascular tumor with a higher chance of achieving complete devascularization [12,36].…”

“…Significant intraoperative blood loss is expected so preoperative transarterial embolization has proved beneficial [9,10]. Percutaneous direct intratumoral embolization can also be done with same efficacy [11][12][13][14]. Supraglottic laryngectomy and lateral pharyngotomy are commonly used approaches for managing these paragangliomas [15][16][17][18][19][20].…”
