Indications for permanent SCS implantation
(pts 30)
|
Group A (five pts, 14·7%: three in Rutherford class 4 and two in Rutherford class 5): refractory sever ischaemic pain and trophic lesions with a very compromised distal arterial bed, not responding to medical treatment nor submitted to previous revascularisation.
Group B (nine pts, 26·5%: seven in Rutherford class 5, two in Rutherford class 6): after late bypass failure.
Group C (seven pts, 20·6%: four in Rutherford class 5 and three in Rutherford class 6): after early failure of multiple extreme attempts of endovascular and surgical treatment.
Group D (eight pts, 23·5%: three in Rutherford class 5 and five in Rutherford class 6): adjuvant therapy after successful revascularisation.
Hand ischaemia caused by steal syndrome in one haemodialysis patient (2·9%).

Outcomes
(pts 30)
|
Group A: healing in an average period of 1·2 ± 0·5 months.
Group B: healing of six pts (Rutherford 5) after 2·7 ± 1·4 months and one SCS removal for infection. Healing of one patient (Rutherford 6) after 7 months and incomplete healing of one patient (Rutherford 5), and one failure of SCS (Rutherford 6) with amputation of the lower limb.
Group C: complete healing of four pts in 3·4 ± 1·5 months (three pts in Rutherford class 5 and one in Rutherford class 6). Incomplete healing in one patient (Rutherford 5) and two cases of SCS removal in two pts (Rutherford 6) after 5 and 8 months, with amputation of the lower limb.
Group D: healing of seven pts in 4·6 ± 2·7 months. Incomplete healing in one patient. Two SCS removal for surgical wound dehiscence after 2 and 3 years.
Healing of hand lesion after 7 weeks in the haemodialysis patient.
