The association between medical risk factors and the outcome of foot ulcers was evaluated in 208 consecutive diabetic patients with severe peripheral vascular disease (systolic toe blood pressure < or = 45 mm Hg). All patients were treated and followed by the same foot care team. Eighty patients healed primarily, 83 healed after a minor or major amputation, and 45 died. The systolic toe blood pressure was higher among primary healed (30 +/- 13 mm Hg) compared with amputated (22 +/- 15 mm Hg; p < 0.001) and deceased patients (20 +/- 14 mm Hg; p < 0.001). The patients were comparable regarding age, sex, and diabetes and wound duration. Only 41 (19%) patients had intermitten claudication, whereas 153 (77%) lacked palapble pedal pulses, 36% of whom healed primarily. Rest pain occurred in 72 (33%) patients, 38 (47%) of whom had an amputation and 18 (25%) who healed primarily (p < 0.01). Peripheral edema and proteinuria were more common among patients who healed after amputation compared with those who healed primarily (p < 0.001 and p < 0.01, respectively). Signs of sensory neuropathy were found in 158 (77%) patients. There were no differences concerning cardiovascular disease, smoking habits, or short-term metabolic control between patients who healed primarily or after an amputation. In conclusion, diabetic patients with foot ulcers and severe peripheral vascular disease with low systolic toe blood pressure were not excluded from the possibility of primary healing. The most important risk factors for amputation were a systolic toe pressure of less than 30 mm Hg, peripheral edema, rest pain, and proteinuria.

Fifty-four patients underwent 56 profundaplasties for limb salvage. All had stenosis greater than 50% in diameter of the deep femoral artery and associated superficial femoral artery occlusive disease. After profundaplasty, ischemic ulcers healed in 9 of 17 (53%) patients. Rest pain was relieved in 6 of 19 (32%) and areas of ischemic necrosis healed in 7 of 20 (35%). Cumulative patency of the deep femoral artery was 49% at 3 years but fell to 21% at 5 years, whereas cumulative limb salvage was 49% and 36%, respectively. Eleven of the required 28 amputations were performed in the immediate postoperative period. Profundaplasty was used to lower the amputation level and preserve the knee joint in six patients. The other five early amputations occurred in severely ischemic limbs without distal vessels suitable for bypass. The profundaplasty remained patent in all 19 patients who underwent below-knee amputation and 16 (84%) became ambulatory with a prosthesis. Hemodynamic data provided by determination of the profundapopliteal collateral index predicted limb salvage in 10 of 11 (91%) of limbs when the index value was less than or equal to 0.19. Other clinical criteria, such as preoperative ankle-brachial index and the presence of diabetes mellitus, had no predictive value. Isolated profundaplasty for limb salvage is an effective first procedure for selected patients and provides a reasonable alternative to primary amputation or high-risk distal bypass. When amputation is inevitable, effective perfusion of the profunda femoris artery is essential for preservation of the knee joint and results in a high degree of functional rehabilitation.

With the ageing population and increasing incidence of diabetes, arterial occlusive disease will become more common as cause of lower limb pain. In the diagnosis of limb pain of arterial origin it is essential to distinguish rest pain from intermittent claudication. Rest pain is associated with high risk of amputation and is therefore an indication for examinations within specialized care. First-line treatment of intermittent claudication instead consists of the management of risk factors and guided exercise. Specialized care consultation is required only in case of intermittent claudication which is refractory to conservative treatment and threatening the ability to work and function. Acute lower limb ischemia is always an indication for emergency assessment.

Critical limb ischemia (CLI) in high surgical risk patients with chronic liver diseases has a grave prognosis with a one-year mortality rate of 20% and a one-year amputation rate of 25% after the initial diagnosis. According to Trans-Atlantic Inter-Society Consensus (TASC)-II Guidelines, revascularization (surgical & endovascular) is the treatment of choice for patients with critical limb ischemia (CLI). The primary goal of revascularization is to relieve ischemic rest pain, heal ulcers, prevent amputation, improve patient's quality of life (limb salvage) and secondary goal was the periprocedural complications. Endovascular techniques include balloon angioplasty, stents, stent-grafts, and plaque debulking procedures. Surgical options, identification of patients at risk of postoperative complications could have an impact on the indications for a procedure as well as permitting modifications of treatment to reduce the surgical risk This study evaluated the treatment out comas after limb salvage angioplasty for patients who otherwise would be candidates for primary amputation due to poor co-morbid conditions as chronic liver disease and diabetes. The clinical evaluation, laboratory investigations and abdominal ultrasonography were performed to all patients to evaluate their liver status. Patients were classified according to Child-pugh classification into child A, B & C. All patients were subjected to either detailed arterial duplex or C.T. angiography to assess their arterial lesions from January 2008- January 2010. 95 patients with critical limb ischemia (Rutherford categories 4, 5, 6) were treated by primary percutaneous transluminal angioplasty (PTA). No patient was excluded on the basis of the extent of arterial occlusive disease. The primary end points were immediate technical success, clinical improvement and limb salvages rates. Secondary end points were periprocedural complications and mortality. Most of the patients were male (54.7%) with mean age 62 (48-70 years). Underlying cirrhosis due to HCV was (82.2%), HBV (5.4%), while mixed viral infections was (12.4%). 54% were categorized as Child B, 32% as child A and 14% as child C. Associated diabetes mellitus was present in 96% of the cases, hypertension in 64.2%, ischemic heart disease in 74% and hyperlipedemia in 32%. Rest pain, tissue loss, or both, were the presenting symptoms in 83% while infection and ulcer were present in the other 17% of patients. The total numbers of interventions were 154; the treated lesions were 89 in the tibial arteries, 12 in the popliteal artery, 44 in the superficial femoral artery, 3 in the common femoral artery and 6 in the iliac arteries with initial technical success rate of 93.6% and periprocedural complications of 12.6%. All patients were in Rutherford clinical category 4, 5, 6 none of these patients had a previous bypass operation. Mean follow-up was 15 months. The limb-salvage rate was 87.4%. Eighty patients (84.2%) of toe amputation sites healed primarily. three patients with rest pain had resolution of their symptoms after angioplasty. All technical failures were due to inability to cross the lesions. Of the 6 technical failures, 4 required amputation, and 2 refused any further therapy.
