Development of alginate and gelatin-based pleural and tracheal sealants.

Acta Biomater 2021 Jul 7. Epub 2021 Jul 7.

Department of Medicine, University of Vermont, Burlington, VT, USA. Electronic address:

Pleural and tracheal injuries remain significant problems, and an easy to use, effective pleural or tracheal sealant would be a significant advance. The major challenges are requirements for adherence, high strength and elasticity, dynamic durability, appropriate biodegradability, and lack of cell or systemic toxicity. We designed and evaluated two sealant materials comprised respectively of alginate methacrylate and of gelatin methacryloyl, each functionalized by conjugation with dopamine HCl. Read More

Republished: Multiplug flow control technique as a novel transarterial curative approach for the endovascular treatment of cerebrovascular malformations.

J Neurointerv Surg 2021 Jun 9. Epub 2021 Jun 9.

Radiology Department, Private Koru Hospital, Ankara, Turkey.

Herein, we describe the use of a novel multiplug flow control technique for the curative transarterial embolisation of cerebrovascular malformations using liquid embolic agents (LEAs). The idea behind the use of this technique is to substantially control or arrest flow during LEA injection, with multiple plugs simultaneously formed from microcatheters that are placed within all or multiple feeders, so that the penetration of LEAs is facilitated, with flow control decreasing the washout of a malformation. This technique enables the complete occlusion of a vascular malformation in a shorter injection time than that in other methods because penetration is achieved faster. Read More

Nanocomposite hyaluronic acid-based hydrogel for the treatment of esophageal fistulas.

Mater Today Bio 2021 Mar 27;10:100109. Epub 2021 Mar 27.

Institut de Science et d'Ingénierie Supramoléculaires, CNRS, UMR 7006, Université de Strasbourg, 8 rue Gaspard Monge, 67000 Strasbourg, France.

Fistulas are abnormal connections between two body parts that can impair the quality of life. The use of biological glues represents the least invasive procedure to fill the fistula; however, it is limited by the need of multiple injections, the persistence of infection and the failure in the treatment of high-output fistulas. We describe herein the use of an injectable nanocomposite hydrogel that is able to form a tissue-mimicking matrix as an innovative material for the treatment of esophageal fistulas. Read More

J Surg Case Rep 2021 Feb 19;2021(2):rjaa605. Epub 2021 Feb 19.

Intensive Care Unit, Gold Coast University Hospital, Southport, Australia.

The formation of a pulmonary arteriovenous malformation (PAVM) following penetrating chest trauma is a rare occurrence, often rapidly fatal or requiring emergency surgery. Even rarer still, is for the malformation to formed by an entangled and grossly tortuous network of multiple arteries and veins, with symptoms and eventual presentation to a medical facility taking place years after the initial injury. Without substantial literature available, and nil regarding instances of more than one involved artery and vein, we present the case of a complex left-sided PAVM, becoming symptomatic 15 years after a chest-wall stabbing.
