Aim:
The purpose of the study was to examine overall survival and the incidence of major adverse cardiovascular events, as well as economic expenditures for treatment of patients with occlusion of the femoropopliteal-tibial segment and critical ischaemia in low competence of the outflow channel, with a poor prognosis for endovascular or open revascularization of lower-limb arteries.
Patients And Methods:
We studied the results of treating a total of 68 patients with lower-limb critical ischaemia and low parameters of the outflow channel competence. Primary arterial reconstruction was performed in 48 cases. At various terms after revascularization due to thrombosis of the reconstruction zone and the development of gangrene, amputation of the lower limb was performed: at 3 to 11 (n=25) and at 12 to 24 (n=25) months. Primary amputation of the lower limb was performed in 20 patients. The endpoints of the study included overall survival, the incidence of major adverse cardiovascular events, and economic expenditures for the in-hospital treatment. The average duration of follow-up amounted to 2 years.
Results:
The obtained findings demonstrated that in patients with lower-limb critical ischaemia and low parameters of the outflow channel competence, redo arterial reconstructions and amputation within 11 months, as well as a high level of surgical risk were associated with a low overall survival rate and the development of major adverse cardiovascular events in the remote period. Secondary surgical interventions on the major vessels significantly increased the cost of treatment.
