Segmental vessel sparing during convex growth arrest surgery--a modified technique

Area of Science:

• Neurosurgery
• Spinal Surgery
• Pediatric Orthopedics

Background:

• Segmental vessel ligation during spinal surgery increases the risk of neurological complications.
• The extent of ligation directly correlates with the severity of potential spinal cord damage.
• Clinical practice necessitates caution when ligating multiple segmental arteries.

Purpose of the Study:

• To prevent segmental vessel ligation during convex growth arrest surgery.
• To mitigate the risk of spinal cord ischemia and subsequent neurological injury.
• To enhance patient safety in complex spinal deformity correction.

Main Methods:

• A modified convex growth arrest surgical technique was employed in two patients.
• Segmental vessels were mobilized, elevated, and protected using surgical slings.
• A rib graft was inserted beneath the protected vessels into the vertebral body.

Main Results:

• Successful sparing of three out of five segmental vessels in the first patient.
• Complete sparing of all five segmental vessels in the second patient.
• Absence of any neurological complications in both treated patients.

Conclusions:

• A novel, straightforward surgical technique effectively avoids segmental vessel ligation.
• This method significantly decreases the risk of neurological injury in a high-risk surgical population.
• The technique offers a safer alternative for convex growth arrest procedures.
