Endovascular strategies for the treatment of critical infrageniculate peripheral arterial occlusive disease exist and are becoming the primary methodology for such lesions at many centers. Although technically feasible for experienced operators, the evidence to support this strategy for below the knee (BTK) interventions is still evolving. We studied the 6-month and 1-year outcomes of percutaneous transluminal angioplasty (PTA) alone, PTA with stenting, and excimer laser recanalization for BTK lesions in patients with critical limb ischemia. Between September 2002 and June 2005, 443 patients (355 Rutherford category 4, 82 category 5, 6 category 6) underwent intervention for 681 BTK lesions. Follow-up was performed at 6-month intervals after index intervention: limb salvage data were recorded and duplex ultrasonography was performed to measure the patency of treated areas. The primary patency and limb salvage rates of the entire population were 85.2% and 97.0% and 74.2% and 96.6% at 6 months and 1 year, respectively. Stratified for the treatment strategy (PTA alone in 79, PTA with stenting in 300 patients, and excimer laser in 64), 1-year primary patency rates were 68.6%, 75.5%, and 75.4%, whereas the limb salvage rates were 96.7%, 98.6%, and 87.9% for each modality, respectively. Endovascular intervention will become the primary treatment for BTK lesions in patients with critical limb ischemia, with 1-year primary patency and limb salvage rates that compare favorably with published surgical data. Prospective, randomized, multicenter trials will be needed to further establish the role of endovascular intervention in this challenging patient group.

Diabetic Foot Osteomyelitis

Background: Diabetic foot osteomyelitis is common and causes substantial morbidity, including major amputations, yet the optimal treatment approach is unclear. We evaluated an approach to limb salvage that combines early surgical debridement or limited amputation with antimicrobial therapy. Methods: We conducted a retrospective cohort study of patients treated between May 1, 2005, and May 31, 2007. The primary end point was cure, defined as not requiring further treatment for osteomyelitis of the affected limb. The secondary end point was limb salvage, defined as not requiring a below-the-knee amputation or a more proximal amputation. Results: Fifty patients with diabetic foot osteomyelitis met the study criteria. Initial surgical management included local amputation in 43 patients (86%) and debridement without amputation in seven (14%). Most infections (n = 30; 60%) were polymicrobial, and Staphylococcus aureus was the most common pathogen (n = 23; 46%). Parenteral antibiotics were used in 45 patients (90%). Patients who had pathologic evidence of osteomyelitis at the surgical margin received therapy for a median of 43 days (interquartile range [IQR], 36–56 days), whereas those without evidence of residual osteomyelitis received therapy for a median of 19 days (IQR, 13–40 days). Overall, 32 patients (64%) were considered cured after a median follow-up of 26 months (IQR, 12–38 months). Fifteen of 18 patients (83%) who failed initial therapy were treated again with limb-sparing surgery. Limb salvage was achieved in 47 patients (94%), with only three patients (6%) requiring below-the-knee amputation. Conclusions: In patients with diabetic foot osteomyelitis, surgical debridement or limited amputation plus antimicrobial therapy is effective at achieving clinical cure and limb salvage.

Quality Imaging

Despite recent guideline updates on peripheral artery disease (PAD) and critical limb ischemia (CLI) treatment, the optimal treatment for CLI is still being debated. As a result, care is inconsistent, with many CLI patients undergoing an amputation prior to what many consider to be mandatory: consultation with an interdisciplinary specialty care team and a comprehensive imaging assessment. More importantly, quality imaging is critical in CLI patients with below-the-knee disease. Therefore, the CLI Global Society has put forth an interdisciplinary expert recommendation for superselective digital subtraction angiography (DSA) that includes the ankle and foot in properly indicated CLI patients to optimize limb salvage. A recommended imaging algorithm for CLI patients is included.

Limb Salvage Procedure

In this retrospective review, 19 diabetic patients with significant lower-extremity pathology were assessed to determine the success of limb salvage in cases of varying complexity. The patients were either scheduled or at risk for below-the-knee amputation before intervention. After the limb-salvage procedure, patients were followed for 4 months to 9 years. Eighteen patients went on to have successful procedures, avoiding below-the-knee amputation; one patient had an above-the-knee amputation. The results demonstrate the benefits of an aggressive team approach with limb salvage as a goal. (J Am Podiatr Med Assoc 92(8): 457-462, 2002)

Iliac Occlusion

Background Roadway injuries are a leading cause of lower extremity vascular trauma. Treating these injuries involves controlling life-threatening hemorrhage and restoring distal perfusion. Materials and Methods We describe a unique presentation of chronic iliac artery occlusion in the setting of blunt trauma requiring extra-anatomic bypass for maximal limb salvage. Results A 50-year-old male presented after a pedestrian versus auto accident. He had mangled bilateral lower extremities and was taken emergently for lower extremity amputations. He was found to have chronic left common iliac occlusion and a femoral-femoral bypass was performed to assist with healing his left below-the-knee amputation Discussion Lack of adequate perfusion can cause poor outcomes in limb salvage. This case demonstrated that lower extremity trauma can be complicated by chronic vascular disease. Reperfusion and adequate wound healing can be accomplished by using bypass grafting after more traditional reperfusion techniques fail.

Introduction: Sirolimus coated balloon (SCB) is a promising treatment option to prevent restenosis for peripheral arterial occlusive disease (PAOD). This is a pilot first-in-human study of MagicTouch percutaneous transluminal angioplasty (PTA) SCB for treatment of PAOD for both femoropopliteal and below the knee arteries (BTK). Material and Methods: Xtreme Touch-Neo [MagicTouch PTA] Sirolimus Coated Balloon (XTOSI) pilot study is a prospective, single-arm, open-label, single-center trial evaluating MagicTouch PTA SCB for symptomatic PAOD. Primary endpoint was defined as primary patency at 6 months (duplex ultrasound peak systolic velocity ratio ≤2.4). Secondary endpoints included clinically driven target lesion revascularization (CD-TLR), amputation free survival (AFS), all-cause mortality, and limb salvage success. Results: Fifty patients were recruited. The mean age was 67 (n=31 [62%] males). SCB was applied to femoropopliteal in 20 patients (40%) and BTK in 30 patients (60%). Majority of treatments (94%) were performed for limb salvage indications (Rutherford scores 5 or 6). This was a high risk cohort, in which 90% had diabetes, 36% had coronary artery disease, 20% had end stage renal failure, and American Society of Anaesthesiologists (ASA) score was 3 or more in 80%. Mean lesion length treated was 227±81 mm, of which 36% were total occlusions. Technical and device success were both 100%. At 30 days, mortality was 2% and major limb amputation was also 2%. Six-month primary patency was 80% (88.2% for femoropopliteal; 74% for BTK). At 12 months, freedom from CD-TLR was 89.7% (94.1% for femoropopliteal; 86.3% for BTK), AFS was 81.6% (90.0% for femoropopliteal; 75.9% for BTK), all-cause mortality was 14.3% (10.0% for femoropopliteal; 17.2% for BTK), and limb salvage success was 92.9% (94.4% for femoropopliteal; 91.7% for BTK). There was a statistically significant increase between baseline and 6-month toe pressures for both femoropopliteal (57.3±23.3 mm Hg vs 82.5±37.8 mm Hg; p<.001) and BTK lesions (52.8±19.2 mm Hg vs 70.7±37 mm Hg; p<.037). At 12 months, wound healing rate was 33/39 (84.6%). Conclusions: MagicTouch PTA SCB in the XTOSI study showed promising 6-month primary patency and encouraging 12-month freedom from CD-TLR, AFS, and limb salvage rates. No early safety concerns were raised. Randomized trials are needed to investigate the safety and efficacy of SCB for treatment of PAOD.
