Summary of common complications of LITT and recommendation to avoid

	Reported complication	Recommendation	Reference
1	Arteria injury leading to hemorrhage	• Choosing the safer trajectory even if it is longer (Jethwa et al.)	Jethwa et al. (1 patient), Pruitt et al. (3 patients)
2	Refractory brain edema due to large lesion size	• Ideal lesion: < 3 cm in diameter, well defined. • Staged procedure for larger lesion. • Pre procedure steroids (Jethwa et al.)	Jethwa et al. (1 patient)
3	Thermal injury to a nearby vital structure	• Using smaller diffusing tips. • Use caution when target lesion is not adjacent to CSF space (act as a protective heat sink) (Pruitt et al.)	Jethwa et al. (1 patient), Pruitt et al. (3 patients)
4	Catheter malposition	• Using an alignment rod. • Avoid use of plastic skull anchors (Pruitt et al.)	Jethwa et al. (1 patient), Pruitt et al. (4 patients)
