Abstract:
Background. Infrainguinal revascularization procedures
are often the main in treating peripheral artery disease
(PAD) and restoring vital blood flow to the lower extremities. Synthetic grafts such as PTFE or Dacron are considered
when autogenous vein grafts are not available. Distal venous patches, strategically attached to these grafts, improve
vascular dynamics, foster optimal healing, and augment
vessel compliance. This reduces complications, prolongs
graft viability, and improves results for limb preservation.
Objective of the study. to meticulously evaluate venous
patch efficacy in infrainguinal bypass revascularization
with synthetic grafts. Aims include assessing their influence
on graft patency optimization, complications mitigation,
and long-term limb salvage rate augmentation. Material
and methods. Systematic searches of PubMed and Google
Scholar using keywords like „infrainguinal bypass”, „venous
patch” and „synthetic graft”. Inclusion criteria focused on
English-language peer-reviewed articles from the last two
decades. Results. Studies reveal significant advantages of
venous patches in infrainguinal bypass revascularization
with synthetic grafts. Venous patches increase graft patency
rates and decrease thrombosis and infections. Autogenous
vein segments are preferred, with different dimensions and
configurations observed. Subgroup examinations indicated benefits for older patients with vascular comorbidities.
Limitations include surgical methodology disparities and
potential biases in retrospective analyses. Conclusion. Distal venous patches have remarkable clinical effectiveness in
infrainguinal bypass revascularization, improving graft patency and reducing complications. Despite limitations, they
are key adjunctive strategies for enhancing the results of
this procedure.
