In the August 2002 issue, there was an error in the printed version of the article “Subintimal Angioplasty of Isolated Infragenicular Vessels in Lower Limb Ischemia: Long-term Results” by Ingle et al. (J Endovasc Ther. 2002;9:411–416). In the Methods sections of the abstract and the text (pages 411 and 412), the dimension of occlusion length was erroneously given as millimeters instead of centimeters; the corrected sentence reads: The median length of occlusion was 6 cm (range 1–10) in the below knee popliteal arteries, 4 cm (range 1–4) in the tibioperoneal trunk, 21 cm (range 1–35) in the anterior tibial artery, 10 (1–30) in the posterior tibial artery, and 5 (range 1–20) in the peroneal artery. We apologize to Mr. Ingle and his coauthors at the Leicester Royal Infirmary for this editing error. The online record of the article in both HTML and print versions has been corrected.

Aims: Knowledge about branching pattern of the popliteal artery is very important in any clinical settings involving the anterior and posterior tibial arteries. This study aims to elucidate the anatomical variation patterns and common types of anterior tibial artery (ATA) and posterior tibial arteries (PTA) in the general population in China. Material and methods: Anatomical variations of ATA, PTA, and peroneal artery were evaluated with ultrasound in a total of 942 lower extremity arteries in 471 patients. Results: Three patterns of course in the PTA were ultrasonographically identified:  1) PTA1: normal anatomy with posterior tibial artery entering tarsal tunnel to perfuse the foot (91.5%),  2) PTA2: tibial artery agenetic, and replaced by communicating branches of peroneal artery entering tarsal tunnel above the medial malleolus to perfuse the foot (5.9%), and 3) PTA3: hypoplastic or aplastic posterior tibial artery communicating above the medial malleolus with thick branches of peroneal artery to form a common trunk entering into the tarsal tunnel (2.4%). In cases where ATA  was hypoplastic or aplastic, thick branches of the peroneal artery replaced the anterior tibial artery to give rise to dorsalis pedis artery, with a total incidence of 3.2 % in patients, and were observed more commonly in females than in males. Hypoplastic or aplastic termini of ATA and PTA, with perfusion of the foot solely by the peroneal artery, was identified in 1 case. In another case, both communicating branches of the peroneal artery and PTA entered the tarsal tunnel to form lateral and medial plantar arteries.Conclusions: Anatomical variation of ATA and PTA is relatively common in the normal population. Caution should be exercised with these variations when preparing a peroneal artery vascular pedicle flap grafting. Ultrasound evaluation provides accurate and reliable information on the variations.

The use of standard anterolateral and anteromedial portals in ankle arthroscopy results in reduced risk of vascular complications. Anatomical variations of the arterial network of the foot and ankle might render the vessels more susceptible to injury during procedures involving the anterior ankle joint. The literature, to our knowledge, reports only one case of a pseudoaneurysm involving the peroneal artery after ankle arthroscopy. Here, we report the unusual case of a 48-year-old man in general good health with the absence of the anterior tibial artery and posterior tibial artery. The patient presented with a pseudoaneurysm of the perforating peroneal artery following ankle arthroscopy for traumatic osteoarthritis associated with nonunion of the medial malleolus. The perforating peroneal artery injury was repaired by performing end-to-end anastomosis. The perforating peroneal artery is at higher risk for iatrogenic injury during ankle arthroscopy in the presence of abnormal arterial variations of the foot and ankle, particularly the absence of the anterior tibial artery and posterior tibial artery. Before ankle arthroscopy, surgeons should therefore carefully observe the course of the perforating peroneal artery on enhanced 3-dimensional computed tomography, especially in patients with a history of trauma to the ankle joint.

Background: The purpose of this study was to quantitatively and qualitatively assess relative arterial contributions to the calcaneus. Method: Fourteen cadaveric ankle pairs were used. In each specimen, the posterior tibial artery, peroneal artery, and anterior tibial artery were cannulated and used for contrast-enhanced magnetic resonance imaging (MRI) and computed tomography (CT). Quantitative MRI analysis of the pre- and postcontrast MRI scans facilitated assessment of relative arterial contributions. In addition, postcontrast MRIs were used to measure all perfused arterial entry points and scaled to a 3-dimensional calcaneus model. Contrast-enhanced CT imaging was assessed to further delineate the extraosseous arterial course. Two pairs underwent infusion of diluted BaSO4 through a constant-pressure pump using extended infusion duration. Results: Quantitative MRI findings indicated the peroneal artery provided 52.6% of the calcaneal arterial supply, 31.6% from the posterior tibial artery, and 15.8% from the anterior tibial artery. The cortical entry points were found in fairly consistent patterns along calcaneal cortical surfaces. All specimens demonstrated intraosseous anastomoses between lateral and medial entry points at common locations. Conclusions: The peroneal artery was found to provide the largest calcaneal arterial contribution, followed by the posterior tibial artery and anterior tibial artery. A rich anastomotic arterial network was found supplying the calcaneus. Clinical Relevance: This study provides quantitative and qualitative findings of the relative arterial contribution of the calcaneus. This knowledge can help expand our understanding of calcaneal vascularization, demonstrate the vascular impact of calcaneal fracture and surgery, and facilitate future research on the arterial anatomy of the calcaneal soft tissue envelope.

Objectives The main factor in the healing of foot ulcers in diabetic patients is adequate perfusion. There is no consensus on whether direct or indirect revascularization is more effective in leg revascularization. At the centre of that debate, there is a disagreement about whether collateral circulation is sufficient or not. Our aim is to evaluate collateral circulation activity between angiosomes in the feet of diabetic patients by evaluating the level of occlusion in leg arteries and comparing the angiosome regions that have necrosis. Methods The study included 61 patients. All had undergone CT angiography to the lower extremity prior to any revascularization of the leg arteries between September 2014 and September 2016. Stenosis was evaluated on the anterior tibial artery, the posterior tibial artery and the peroneal artery up to the level of the ankle. The opening of the vessel wall at the narrowest part of the vessel was determined as a percentage. The areas with necrosis were determined according to the angiosomes of the posterior tibial artery, anterior tibial artery and peroneal artery vessels. Results Necrosis of the foot was most common in the posterior tibial artery angiosome. Necrosis in the posterior tibial artery angiosome was independent of the level of posterior tibial artery occlusion; however, it was associated with the occlusion of the anterior tibial artery ( p < 0.05). It was found that anterior tibial artery occlusion over 15% resulted in necrosis in the posterior tibial artery angiosome. Conclusions Collateral circulation between the anterior tibial artery and posterior tibial artery is active and there is almost always occlusion in the posterior tibial artery branches. The posterior tibial artery angiosome is fed by the collateral arteries of the anterior tibial artery even if there is no occlusion of posterior tibial artery at the level of the leg, so indirect revascularization on the anterior tibial artery is sufficient to provide foot circulation.

Background: Wound of lower leg have a poor and delayed healing due to paucity of blood supply. Coverage of defects of leg and foot has always posed a problem for reconstructive surgeon. The objective of this study was to evaluate anatomical basis of various perforator-based flaps in lower limb and their clinical outcome and usefulness.Methods: All patients with post traumatic defects with exposed bones/tendons in the leg and ankle region presenting in MLN Medical college, Allahabad from August 2011 to July 2012 were included in the study.Results: A total 12 patients were included in study. Majority of cases are of compound fracture following accidents involving lower one third of leg. Majority of flaps were based on peroneal artery (5) and posterior tibial artery (5), only 2 flaps were based on anterior tibial artery. Maximum flap length was 21cm and maximum flap rotation was 180º. Complications occurred more in cases having maximum rotation. Result were good in 11 patients and satisfactory in 1 patient with coverage of the defect leading to healing of the wound. More time gap between injury and flap reconstruction leads to more complications and longer hospital stay. Graft site complication occur in 5 cases include partial flap necrosis, infection and venous congestion. There was no complication at the donor site.Conclusions: Perforator based flaps can be used for all large lower leg defects provided there is correct measurement and anatomical knowledge of various perforators, with good functional and cosmetic results.

Purpose: To evaluate the safety and efficacy of vibrational angioplasty in chronic infrapopliteal arterial occlusions. Methods: Twelve patients (9 men, aged 54 to 90 years) with 13 below-knee arterial chronic total occlusions were treated percutaneously using vibrational angioplasty. The occlusions were located in the anterior tibial artery (n=5), the tibioperoneal trunk (n=4), the peroneal artery (n=1), the posterior tibial artery (n=1), and in both the tibioperoneal trunk and peroneal artery (n=2). The length of the lesions ranged from 5 to 14 cm. Results: Recanalization was successful in 12 (92.3%) lesions. In 1 case, the wire perforated the arterial wall; the procedure was abandoned without clinical sequelae. The time to cross the occlusions with the wire ranged from 6 to 19 minutes. No other complications were observed. Clinical follow-up ranged to 18 months. Ten patients with ulceration or gangrene demonstrated good wound healing, and pain was alleviated in all successfully treated patients. Conclusions: Vibrational angioplasty appears feasible as a means of safely recanalizing chronic total occlusions of the infrapopliteal arteries. Further experience should be acquired to assess its short- and long-term effects on this vascular territory.

Purpose: To assess the outcome of subintimal angioplasty in treating isolated infragenicular arterial disease in patients with severe lower limb ischemia. Methods: A retrospective study reviewed 67 consecutive patients (39 men; mean age 76 years, range 41–96) who underwent infragenicular subintimal angioplasty between March 1997 and May 2000 for ischemia in 70 limbs. The median length of occlusion was 6 cm (range 1–10) in the below-knee popliteal arteries, 4 cm (range 1–4) in the tibioperoneal trunk, 21 cm(range 1–35) in the anterior tibial artery, 10 (1–30) in the posterior tibial artery, and 5 (range 1–20) in the peroneal artery. Results: The technical and clinical success rates were 86% and 80%, respectively. In the 10 (14%) patients with a technical failure, 3 underwent successful bypass, 4 had an amputation, 1 had a lumbar sympathectomy, and 2 were treated conservatively. Of the 4 (6%) limbs that did not achieve clinical success, 2 patients required femorodistal bypass and their ulcers improved; in the other 2, ulcerations did not heal completely. The cumulative limb salvage rate and freedom from critical limb ischemia (CLI) quantified by Kaplan-Meier life-table analysis were 94% and 84% at 36 months. Mortality rates were 19% at 1 year, 43% at 2 years, and 51% at 3 years. In a subgroup analysis, the rate of CLI was significantly lower in nondiabetics (4%) and than in diabetics (24%, p=0.02), but neither survival nor amputation rates were significantly different. Conclusions: Subintimal angioplasty is a safe and effective procedure for treating isolated crural vessels in patients with severe lower limb ischemia.

Purpose: To describe a novel technique designed to safely and precisely deploy the Supera stent accurately at the ostium of the proximal superficial femoral artery (SFA) without compromising the profunda and common femoral arteries. Technique: After antegrade crossing of the chronic total occlusion (CTO) at the SFA ostium and accurate predilation of the entire SFA lesion, a retrograde arterial access is obtained. The Supera stent is navigated in retrograde fashion to position the first crown to be released just at the SFA ostium. Antegrade dilation is performed across the retrograde access site to obtain adequate hemostasis. The technique has been applied successfully in 21 patients (mean age 78.1±8.2 years; 13 men) with critical limb ischemia using retrograde Supera stenting from the proximal anterior tibial artery (n=6), the posterior tibial artery (n=2), retrograde stent puncture in the mid to distal SFA (n=2), the native distal SFA/proximal popliteal segment (n=6), and the distal anterior tibial artery (n=5). No complications were observed. Conclusion: Distal retrograde Supera stent passage and reverse deployment allow precise and safe Supera stenting at the SFA ostium.
