As the channel(s) fill the tubing needs to be further elevated and that part of the lesion is field, the angiocatheter is slowly further withdrawn, and as a new channel is entered the fluid column starts advancing.Materials From 2009–2015 in 154 patients with LM, 34 were microcytic, (500 micron range), treated using the gravity technique, with Doxycycline and or BleomycinResults Significant improvement was noted in most patients, usually towards the 2 or 3rd treatment, both clinically and by cross section imaging. No complications occurred.Conclusion Our gravity technique permits treating lesions with true microcytic channels in a safe and effective manner.Disclosures A. Berenstein: None. ER -
