Histoacryl glue in microvascular surgery

Area of Science:

• Vascular Surgery
• Biomaterials Science
• Surgical Innovation

Background:

• Microvascular anastomosis is crucial for reconstructive surgery.
• Traditional suturing can be time-consuming and prone to bleeding.
• Exploring adjuncts to improve anastomosis outcomes is an ongoing area of research.

Purpose of the Study:

• To evaluate the efficacy and safety of Histoacryl glue as an adjunct in microvascular anastomosis.
• To assess the impact of Histoacryl glue on surgical efficiency (ischemic time, bleeding).
• To histologically examine the tissue response to Histoacryl glue and sutures post-anastomosis.

Main Methods:

• A rat model was utilized to perform microvascular anastomosis.
• Histoacryl glue was employed as an adjunct during the anastomosis procedure.
• Ischemic time and bleeding upon clamp removal were quantified.
• Histological analysis of the anastomosis site was performed at one and three weeks post-surgery.

Main Results:

• Histoacryl glue use was associated with decreased ischemic time.
• Diminished bleeding was observed upon clamp removal in the Histoacryl group.
• Histological examination revealed a mild foreign body inflammatory response to the glue and sutures.
• No instances of media necrosis were observed.
• Only minimal fibrointimal proliferation was noted at the anastomosis site.

Conclusions:

• Histoacryl glue demonstrates potential as an effective adjunct for microvascular anastomosis.
• The use of Histoacryl glue enhances surgical efficiency by reducing ischemic time and bleeding.
• The observed histological findings suggest good tissue compatibility and a manageable inflammatory response.
