Mallela DP, Bose S, Shallal CC, Goldsborough E, Xun H, Chen J, Stonko DP, Brandacher G, Sacks J, Kang SH, Hicks CW. A systematic review of sutureless vascular anastomosis technologies. Semin Vasc Surg 2021; 34:247-259. [PMID: 34911631 DOI: 10.1053/j.semvascsurg.2021.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 10/05/2021] [Accepted: 10/06/2021] [Indexed: 11/11/2022]
Abstract
Vascular anastomoses typically involve a handsewn technique requiring significant surgical training, expertise, and time. The aim of our systematic review was to identify and describe sutureless vascular anastomosis techniques. We performed a systematic review of all sutureless vascular anastomosis technologies published in MEDLINE, PubMed, Embase, CINAHL, Cochrane, Web of Science, and Scopus Library databases and a patent review using US Patent and Trade Office Application, US Patent and Trademark Office Patent, Google Patents, Lens, Patent Quality Through Artificial Intelligence, SureChEMBL, and E-Space Net. Data from inclusion studies and patents published between January 1, 1980 and July 15, 2021 were abstracted to describe their category, anastomosis type and configuration, study types, and advantages and disadvantages encountered with each technology. Two hundred eleven original studies and 475 patents describing sutureless vascular anastomosis technologies were identified. In the literature, stents/stent-grafts/grafts (n = 61), lasers (n = 53), and couplers (n = 27) were the predominant device categories. In the patent review, adhesive technologies (n = 103), stents/stent-grafts/grafts (n = 68), and mechanical connectors (n = 61) predominated. The majority of studies involved in vivo animal studies (n = 193); 32.2% (n = 68) of investigations involved human trials; and 17.9% (n = 85) of patent technologies were approved by the US Food and Drug Administration. The main advantages described for sutureless anastomosis technologies included faster procedure time and greater patency rates compared with handsewn anastomoses. The main disadvantages included reduced vessel compliance, stenosis, leakage, and device costs. The appeal of sutureless technology is substantiated by numerous animal trials, but their use in humans remains limited. This may be a reflection of strict regulatory criteria and/or vascular complications associated with currently available technologies.

Adv Healthc Mater 2018; 7:e1800702.

Abstract
Microvascular anastomosis is a common part of many reconstructive and transplant surgical procedures. While venous anastomosis can be achieved using microvascular anastomotic coupling devices, surgical suturing is the main method for arterial anastomosis. Suture-based microanastomosis is time-consuming and challenging. Here, dissolvable sugar-based stents are fabricated as an assistive tool for facilitating surgical anastomosis. The nonbrittle sugar-based stent holds the vessels together during the procedure and are dissolved upon the restoration of the blood flow. The incorporation of sodium citrate minimizes the chance of thrombosis. The dissolution rate and the mechanical properties of the sugar-based stent can be tailored between 4 and 8 min. To enable the fabrication of stents with desirable geometries and dimensions, 3D printing is utilized to fabricate the stents. The effectiveness of the printed sugar-based stent is assessed ex vivo. The fabrication procedure is fast and can be performed in the operating room.

Abstract
A tubular polyurethane (PU) sandwich-like, adipose-derived stem cell (ADSC)/gelatin/alginate/ fibrin construct was fabricated using a double-nozzle, low-temperature (—20°C) deposition technique. The ADSCs survived the fabrication and cryopreservation stages by incorporating a cryoprotectant (glycerol or dimethyl sulfoxide (DMSO)) in the cell/hydrogel system. With 5% DMSO or 10% glycerol alone in the hydrogel, the cell viabilities were retained (73% and 62%, respectively). The three-dimensional construct was effectively preserved below —80°C for more than 1 week. After the freeze/thaw processes, cell viability and proliferation ability were regained. This strategy has the potential to be widely used in complex organ manufacturing techniques.

Abstract
Rapid prototyping (RP) technologies are a set of manufacturing processes that can produce very complex structures directly from computer-aided design models without structure-specific tools or knowledge. These technologies might eventually enable the manufacture of human livers to create functional substitutes for treating liver failure or dysfunctionality. However, the approaches used currently face many challenges, such as the complex branched vascular and bile ductular systems and the variety of cell types, matrices and regulatory factors involved in liver development. Here, we discuss the challenges and provide evidence for the usefulness of RP in overcoming them.
