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.

After puncturing the aorta through the inferior vena cava (IVC) to create an aorto-caval fistula in the mouse, solution containing a drug is infused into the IVC via the same needle, followed by incubation. This method enables more robust drug delivery to the venous endothelium compared to the external route.

This video demonstrates the surgical isolation procedure of the inguinal draining lymph node from a mouse model. Incision of the abdominal region provides access to the inguinal lymph node, which is surgically harvested. The harvested translucent inguinal lymph node can be used for immunological studies.
FAQs
Magnification enlarges small anatomical structures so surgeons can distinguish and manipulate vessels, nerves, and tissue layers that are difficult to handle with the unaided eye. This visual access supports precise hand movements and placement of miniature instruments, allowing repair or connection of delicate structures while limiting unnecessary tissue trauma during the procedure.
Fine sutures allow surgeons to join small structures without overwhelming the tissue with bulky materials. Careful alignment of tissue layers helps restore continuity across the repair and supports accurate integration of the connected surfaces. These requirements make precision essential, because even small positioning errors can affect how delicately manipulated tissues reconnect.
The key difference is the scale of structures that can be treated accurately. Microsurgery combines an operating microscope or high-resolution loupes with miniature instruments and controlled hand movements, extending surgical work to anatomy that is invisible or difficult to manipulate unaided. This capability supports more precise work on small vessels, nerves, and delicate tissues.
Both systems provide the visual enlargement needed to work on very small anatomical structures, but the overview identifies them as alternative magnification systems rather than identical equipment. Their role is to make fine anatomy visible while the surgeon uses miniature instruments and sutures. This combination links enhanced visualization with precise manipulation and tissue-layer alignment.
A microsurgical repair begins with magnified visualization of the target anatomy, followed by controlled manipulation using miniature instruments. The surgeon then uses fine sutures to align the relevant tissue layers and restore continuity. Throughout the process, precise hand movements help limit trauma, which is important when working with vessels, nerves, or other delicate tissues.
Microsurgery is applied in tissue transplantation, reconstructive procedures, and nerve repair, where accurate handling of small structures is important. It also supports experimental studies of organ function and regeneration. In biology, these applications help researchers examine healing, vascularization, and tissue integration, connecting surgical technique with questions about how tissues recover and function.
