This didactic procedure concerns a 70 years old man, with multiple Cardiovascular risk factors, presenting severe Leftt limb critical ischemia with extensive gangrene in the II-III & IV toes.
	He was treated by complete revascularization of both Anterior tibial artery  (True to true lumen) & Posterior tibial artery recanalization, Good final angiographic  result with acceptable Run off.
	 
	Educational objectives
	- 
		How to manage patients with Critical Limb ischemia & BTK vessels reocclusion.
- 
		Optimal techniques to achieve complete revascularization in Critical Limb ischemia.
- 
		How to minimize iodine contrast use during BTK revascularization procedures.
- 
		Carboxy-dioxide angiography during BTK revascularization procedures.
- 
		Drug Coated Balloon in BTK arteries.
