Objectives. To estimate the significance of hydraulic dissection of arteries in treatment of patients with chronic critical limb ischemia as a potential method of artery disobliteration.
Methods. 20 amputated specimens of the arteries isolated from the lower extremity in patients with critical limb ischemia were studied. Hydraulic dissection of the arterial wall, affected by atherosclerosis was performed to disobliterate its lumen. To perform this technique the isotonic fluid was injected sub-adventitially to separate obstructing substrate from the residual wall in the arterial lumen. After atherosclerotic plague separation the last one was extracted via the longitudinal arteriotomy.
Results. The hydraulic disobliteration was completed on the segments of femoral and popliteal arteries over 5±2,1 cm, this index made up 3±1,7 cm on the tibial arteries. In 17 cases the plague was completely separated from the wall and extracted via a arteriotomy orifice as a single conglomerate. At the same time the plague was extracted via the arteriotomy orifice sized 1,5±0,8 cm. Extracted substrate was an atherosclerotic plaque in conjunction with media portion, had a smooth surface and it became thinner in a site of natural reduction of the stenotic lesion. In 3 cases the mechanical endarterectomy was required to perform caused to the fragmentation of the obturating substrate to add the purposed method. Throughout the whole disobliterated site no intima fragments were not detected in macroscopical study of residual wall.
Conclusion. The technique of hydraulic endarterectomy allows to perform dissection of the arterial wall, thereby to separate obstructive substrate from the arterial wall and to extract it in sufficient volume as along the affected segment, as throughout the depth of the arterial wall lesions from the lumen. This technique involves no special equipment to introduce liquid agent into the subadventitial space.
