Table 4 Summary of common complications of LITT and recommendation to avoid

From: Neurosurgical applications of MRI guided laser interstitial thermal therapy (LITT)

  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)
