All of the studies
comparing direct and
indirect revascularization
are retrospective
It is possible that in the “indirect revascularization” groups there was a propensity to collect patients with the most technically challenging disease and the differences in the outcomes may simply reveal basal differences in the extension and type of obstructive disease
![Page 18: Specifics of BTK arterial disease in diabetic patients and … · Direct revascularization according to the angiosome concept seems to be better compared with rev. in terms of wound](https://reader033.vdocuments.us/reader033/viewer/2022042414/5f2f173107c3c361017db8de/html5/thumbnails/18.jpg)
Try to do what is possible and don’t lose time on unrealistic targets!

The value of an angiosome-oriented
revascularization is inversely related
to the function of collateral vessels

Results: The wound(s) interfered with one angiosome in only 24.0% cases.
Conclusions: In CLI, the tissue lesion affects several angiosomesin the majority of the cases.

Extensive tissue damage cannot be
classified on the basis of an
angiosome-oriented scheme. In
these patients complete rev. better
than partial rev

1. Try to do what is possible
and don’t lose time on
unrealistic targets!
2. Consider the rule of
collateral vessel
disease/function
3. Complete revascularization
is better than partial rev. in
Rutherford 6 pts (huge
wounds more than one
angiosome)
