Here, we describe a pre-clinical animal model for studying the pathophysiology of ischemia-reperfusion injury in reconstructive microsurgery. This free skin flap model based on the superficial caudal epigastric vessels in the rat may also allow for the evaluation of different therapies and compounds to counteract ischemia-reperfusion injury-related damage.

Source: Brakkee, E. M., et al. Surgery and Behavioral Testing in the Tibial Neuroma Transposition Model in Rats. J. Vis. Exp. (2023).This video demonstrates a procedure to generate a rat tibial neuroma transposition (TNT) model. After exposing the tibial nerve in the hind leg of an anesthetized rat, transect the nerve. Next, create a subcutaneous tunnel, thread the severed nerve through the tunnel, and suture it in place. In the absence of a target for reinnervation, disorganized axonal...

Angiogenesis in the Ischemic Rat Lung

The lung is perfused by both the systemic bronchial artery and pulmonary arteries. In most lung pathologies, it is the smaller systemic vasculature that shows robust neovascularization. Cessation of pulmonary blood flow promotes brisk bronchial angiogenesis. We provide surgical details of inducing left pulmonary artery ischemia that promotes bronchial neovascularization.
FAQs
The operating microscope enlarges small anatomical structures so the surgeon can isolate tissue and manipulate fine blood vessels, nerves, or ducts. Miniature instruments and microsutures then permit controlled handling at a scale where small movements matter. This precision supports vascular repair, nerve regeneration, transplantation, and ischemia models with greater procedural control.
Anesthesia is maintained throughout the operation, while bleeding and tissue trauma are carefully controlled. These conditions accompany tissue isolation and fine manipulation, helping keep the experimental procedure consistent. In medicine, that consistency matters when researchers compare operative techniques, evaluate treatments, or assess healing and functional recovery after microsurgical intervention.
Microsutures provide a means to secure or reconnect manipulated tissues at the fine scale exposed under magnification. Their use complements tissue isolation, vessel or nerve handling, and duct manipulation rather than replacing those steps. In experimental medicine, this combination supports models of vascular repair, transplantation, and nerve-related procedures in a controlled rat surgical setting.
Rat anatomy contributes to reproducibility because researchers can work with a consistent anatomical framework across experimental procedures. At the same time, adaptable surgical approaches allow microsurgery to target different structures, including blood vessels, nerves, and ducts. This combination supports comparison among studies and helps investigators refine techniques or test interventions in transplantation, ischemia, and regeneration research.
The operative workflow centers on an operating microscope, miniature surgical instruments, and microsutures suited to small anatomical structures. Surgeons also maintain anesthesia while isolating tissues and manipulating vessels, nerves, or ducts. Careful control of bleeding and tissue trauma remains essential throughout the procedure, supporting precise intervention and more reproducible experimental conditions.
Rat microsurgery supports research involving transplantation, vascular repair, nerve regeneration, tissue ischemia, and experimental disease models. Its adaptable procedures allow investigators to study different anatomical targets while applying precise surgical techniques. These applications make the approach useful for evaluating treatments, refining operative methods, and examining biological responses after experimental intervention.
Studies using this approach can address both technical and biological outcomes. Investigators may evaluate a treatment, refine an operative technique, or investigate healing and functional recovery after a microsurgical model. The method therefore connects the immediate surgical procedure with later assessment of repair, regeneration, ischemia, transplantation, or experimental disease processes.
