To date, thick tissue defects are typically reconstructed by applying autologous tissue flaps or engineered tissues. In this protocol, we present a new method for engineering vascularized tissue flap bearing an autologous pedicle, to serve as a substitute to autologous flaps.

Q Suture Technique: A Suturing Technique to Reduce Gap Formation and Increase Tensile Strength in Tendon Repair

In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.

Tools used for visualizing vascular regeneration require methods for contrasting the vascular trees. This film demonstrated a delicate injection technique used to achieve optimal contrasting of the vascular trees and illustrate the potential benefits resulting from a detailed analysis of the resulting specimen using µCT and histological serial sections.

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures. Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

We describe a technique in which a section of the abdominal aorta from a mouse is transplanted orthotopically to just below the renal arteries in an allogeneic or syngeneic recipient. This technique can be useful in studies in which transplantation of large arteries of uniform size is deemed advantageous.
FAQs
Stitch placement must bring the vessel edges together accurately without projecting into or excessively constricting the lumen. This balance supports a continuous passage for blood while creating a seal at the repair site. Poor approximation or excessive narrowing can compromise circulation, so precision directly connects the suture line with postoperative vascular function.
Continuous and individually placed stitches are options for constructing vascular suture lines, and the choice depends on the repair being performed. The overview does not assign one pattern to every situation. Selecting the appropriate arrangement allows the surgeon to approximate the vessel edges while pursuing both secure closure and preservation of the lumen.
A compromised suture line can permit bleeding or interfere with normal blood flow. The repair may also be associated with thrombosis, meaning clot formation, or stenosis, meaning narrowing of the vessel. Because the suture line influences hemostasis, circulation, and healing, its integrity is a central determinant of the surgical outcome.
The surgeon uses a fine needle to pass stitches through the vessel wall, brings the vessel edges into precise approximation, and completes the closure with either continuous or individually placed stitches. The finished line must produce a secure, hemostatic seal while maintaining the vessel lumen, combining bleeding control with preservation of circulation.
Vascular suture lines are used in arterial and venous anastomoses, where vessel segments are joined, as well as in trauma repair and vascular graft attachment. These settings share the need to restore or maintain a blood pathway. The technique therefore applies both to planned vascular procedures and to repairs addressing vessel injury.
A successful line supports restored circulation, controls bleeding, and keeps the vessel lumen sufficiently open. Its performance is reflected in the balance between a hemostatic seal and unobstructed flow, while subsequent healing remains important. Conversely, bleeding, thrombosis, or stenosis signals that the repair has not achieved the intended vascular result.
