“…These two biomaterials have a long clinical history as vascular implants due to their relatively low thrombogenicity and good mechanical properties, but they are not optimal for SG incorporation. The hydrophobic surface of ePTFE is known to drastically limit cell adhesion [13]. Dacron s grafts are less inert, and have been shown to result in slightly improved but still insufficient incorporation [14].…”

“…They are flexible and easily deployed and formation of a neointimal layer is complete between 1 and 3 months after the procedure, with little vessel wall reaction [Toyota et al, 2002]. Surgery is carried out at least 4-6 weeks after stent positioning, thus allowing the formation of a stabilized neointima on the luminal surface of the stent [Cejna et al, 2002]. Each stenting procedure is tailored to the individual patient; the type and number of stents are chosen on the basis of angiographic evaluation (i.e.…”

Objectives: To investigate the long-term results of preoperative stenting of the internal carotid artery (ICA) in complex head and neck paragangliomas (HNP) as well as to report on indications and technical details of the procedure. Method: A comprehensive retrospective review of patients affected by HNP, consecutively operated on and preoperatively treated with stenting of the ICA in a quaternary referral skull base center, was performed. Results: Nineteen patients affected by complex HNP were identified, on whom 21 preoperative stenting procedures were performed. The mean follow-up period after stent insertion was 53.8 months; the patients' age ranged from 33 to 56 years. Fourteen patients were affected by tympanojugular paragangliomas, 4 by vagal paragangliomas and 1 by bilateral carotid body tumors. Five patients presented with recurrent tumors, while 7 presented with multiple or bilateral HNP. There were no complications associated with endovascular procedures. Total tumor removal was accomplished in 52.4% of the cases with 1 recurrence. An advanced stage was the main factor conditioning total removal. Clinical control was obtained in 80% of the patients with residual disease. Total tumor removal from and around the ICA was obtained in 95.2% of the cases. Long-term stent patency was evident in 20 of 21 cases. Conclusions: Preoperative stenting of the ICA represents a safe and effective procedure in selected cases, obviating the need for balloon occlusion or bypass procedures and reducing the risk of intraoperative vascular injury.

“…Comparisons cannot be made regarding the various types of stents used given the insufficient available data. Experimental studies 29,30 have reported that the endograft fabric may induce a graft versus host reaction, subsequently worsening the pre-existing inflammatory response, and Barret et al 27 suggested that a graft versus host reaction may be associated with PAF persistence. In this series, despite the use of varying materials, such as polytetrafluoroethylene (PTFE, n ¼ 4) and Dacron (n ¼ 5), encouraging results were found for inflammation.…”
