Post-operative Infection of Prosthetic Materials or Stents Involving the Supra-aortic Trunks: A Comprehensive Review.
European Journal of Vascular and Endovascular Surgery 2018 December
OBJECTIVE: The aim of this paper was to provide recommendations for diagnosis and management in the setting of infection following open or endovascular reconstructions of the supra-aortic trunks.
METHODS: A review of the Medline database was performed from 1997 to 2017 by a combined strategy of MeSh terms.
RESULTS: The literature search identified 49 publications: 36 studies addressing prosthetic material infections and 13 studies addressing stent infections. A total of 140 cases of prosthetic material infections were reported, mostly involving carotid patches. Surgical treatment was mostly based on complete removal of the infected material followed by in situ arterial reconstruction (86 cases, 62.3%). Peri-operative complications included cranial nerve injury in 17 cases (12.5%), stroke in eight (6.7%), bleeding in four (2.9%), re-infection in five (3.6%), and cardiac failure in three cases (2.2%). Stent infections were reported in 12 patients: eight carotid stents, three subclavian stents and one tandem brachiocephalic subclavian stent. Treatment was not described for one case, was conservative in one case, consisted of stent removal with venous reconstruction in six cases, stent removal without reconstruction because of carotid thrombosis in two cases, and carotid embolisation in two cases. Complications included intra-operative death in one case (9.1%), stroke in two (18.2%), reinfection in one (9.1%), bleeding in one (9.1%), and cardiac failure in one case (9.1%).
CONCLUSION: Appropriate pre-operative imaging is mandatory and treatment modality should be determined by patient condition. Complete removal of the infected material, followed by in situ arterial reconstruction with venous material seems advisable, despite high morbidity. However, alternative strategies may be considered for fragile and high risk patients. A multidisciplinary approach is mandatory to ensure optimum results.
