Stabilizing hemostatic clamp for arterial anastomosis in microneurosurgery. Technical note

Area of Science:

• Neurosurgery
• Vascular Surgery
• Surgical Instrumentation

Background:

• End-to-side anastomosis is a critical procedure in cerebrovascular surgery.
• Achieving simultaneous stabilization and hemostasis of small cortical arteries can be challenging.
• Existing instruments may not adequately address the specific needs of this delicate surgical step.

Purpose of the Study:

• To introduce and evaluate a novel "stabilizing hemostatic clamp" designed for end-to-side anastomosis.
• To assess the clamp's efficacy in facilitating simultaneous stabilization and hemostasis of the cortical artery.
• To determine if the new clamp improves the ease and safety of superficial temporal artery to middle cerebral artery anastomosis.

Main Methods:

• A custom-designed "stabilizing hemostatic clamp" was utilized.
• The clamp was applied to simultaneously stabilize and achieve hemostasis of the cortical artery during anastomosis.
• Anastomosis of the superficial temporal artery with a branch of the middle cerebral artery was performed in 60 patients using the clamp.

Main Results:

• The stabilizing hemostatic clamp successfully facilitated simultaneous stabilization and hemostasis of the cortical artery.
• The procedure involved anastomosis of the superficial temporal artery with a middle cerebral artery branch in 60 patients.
• Clinical effects and control angiography results indicated successful application of the clamp.

Conclusions:

• The newly designed stabilizing hemostatic clamp simplifies end-to-side anastomosis of the cortical artery.
• The instrument aids in achieving simultaneous stabilization and hemostasis, crucial for successful microvascular procedures.
• The clamp facilitates cerebrovascular anastomosis, even with limited surgeon experience.
