Pancreatic islet microvascular vasomotion regulates islet blood distribution and maintains the physiological function of islet β cells. This protocol describes using a laser Doppler monitor to determine the functional status of pancreatic islet microvascular vasomotion in vivo and to assess the contributions of pancreatic islet microcirculation to pancreatic-related diseases.

There are many available options for management of the patient with trigeminal neuralgia. Microvascular decompression, while the most invasive of all options, is also the most effective at achieving long term remission of symptoms. Video instruction on how to maximize efficacy and minimize complications with this procedure is described.

Surgical induction of ischemic brain damage in the rat is a widely used model for stroke research. Here we demonstrate the induction of focal cerebral ischemia by occlusion of the middle cerebral artery. Visualization of the resulting infarct by histological staining and magnetic resonance imaging is also shown.

We present a preparation for visualizing and manipulating calcium signaling in native, intact microvascular endothelium. Endothelial tubes freshly isolated from mouse resistance arteries supplying skeletal muscle retain in vivo morphology and dynamic signaling within and between neighboring cells. Endothelial tubes can be prepared from microvessels of other tissues and organs.
FAQs
Accurate alignment brings the vessel ends together so the reconstructed channel can support restored blood flow. Closely spaced sutures then secure the connection while limiting gaps that could contribute to leakage. In clinical reconstruction, this precision helps protect the vessel lumen and supports the healing and survival of revascularized tissue.
Sutures must pass through the vessel wall in a controlled, closely spaced pattern. This creates a secure anastomosis without unnecessarily injuring the lumen or producing excessive narrowing. The balance is important because the repair must remain mechanically stable while preserving the internal passage needed for blood flow through the reconstructed vessel.
Technical accuracy is the central determinant of whether the repair remains useful. Vessel alignment, needle handling, suture spacing, and protection of the lumen all influence the risk of narrowing, leakage, or injury. These factors ultimately affect patency, meaning continued openness of the vessel, as well as tissue healing and graft survival.
A basic workflow includes working under magnification, handling the vessel and needle with fine instruments, aligning the vessel ends, and placing closely spaced sutures through the vessel wall. The completed connection is then assessed for patency. Each stage addresses a different requirement: precision, structural security, preservation of the lumen, and restoration of flow.
Training should emphasize controlled needle handling, accurate tissue alignment, and assessment of vessel patency. These skills are interdependent: poor handling can disrupt alignment, while inaccurate alignment can compromise the finished connection. Building them systematically is important because small technical errors may influence leakage, narrowing, blood flow, and the survival of repaired or transplanted tissue.
In medicine, the technique is relevant when tissue requires precise vascular reconstruction or revascularization. Applications described for it include free-tissue transfer, replantation, limb reconstruction, and procedures involving transplanted tissue. In these settings, successful repair helps restore blood flow, while the quality of the anastomosis influences healing and the viability of the transferred or reattached tissue.
