Indirect Revascularization

Objective. To optimize the tactics of surgical treatment in patients, suffering chronic ischemia of the lower extremities with the help of elaboration and introduction of a one-staged direct and indirect revascularization into clinical practice. Materials and methods. Analysis of the treatment results in 162 patients, suffering obliterating atherosclerosis of the lower extremities vessels, who were treated in stationary in Department of Vascular Surgery of Zakarpattya Regional Clinical Hospital named after Andriy Novak in 2015 - 2020 yrs. The patients were distributed in accordance to the lower extremities ischemia degree: ІІB – 7 (4.3%), ІІІA – 61 (37.7%), ІІІB – 58 (35.8%), ІV – 36 (22.2%). All the patients have had atherosclerotic affection of femoro-ankle-foot segment of the main arteries with preservation of central blood flow in aorto-iliac segment. Results. Occlusion of femoral artery was noted in all patients. Occlusion of anterior tibial artery was revealed most frequently – in 72% of the patients, than in fibular - in 42% of patients (p=0.00), and equally frequently with occlusion of posterior tibial artery – in 68% (p=0.61). The foot arteries were involved into the process in 51 (31.5%) patients. Affection of 2-3 arteries of the shin were registered more frequently, than occlusion of one artery – in 109 (67.3%) and 48 (26.5%) patients, accordingly. Occlusive-stenotic affection of popliteal artery have had 127 (78.4%) patients. Mostly frequent affection of the shin arteries was observed in basin of anterior tibial artery – in 67 (41.4%) patients, as well as in combined affection of anterior and posterior tibial arteries - in 45 (27.8%) patients. Іsolated affection of posterior artery was revealed in 36 (22.2%) patients. Combined affection of posterior tibial and fibular was observed in 14 (8.6%) patients. Conclusion. Efficacy of indirect revascularization after the arterial inflow restoration is more prognosticated, than efficacy of its isolated conduction in environment of chronic critical ischemia of the lower extremities. Combined application of direct and indirect revascularization guarantees more secure positive result in remote postoperative period and enhancement of the extremities preservation index.

Summary. The aim of the study. To study the effectiveness of the proposed surgical methods in the treatment of critical ischemia of the lower extremities. Materials and methods. In our work the analysis of results of treatment of 36 patients with chronic critical ischemia of the lower extremities who were on treatment in ZOKL of them is presented. Andriy Novak. Grade III A ischemia was diagnosed in 11 patients, grade III B — in 15, grade IV — in 10 patients and studied the microcirculation of the lower extremities in 31 people without pathology of the cardiovascular system, taking into account the angiosomal approach. We found that the highest rates of perfusion units on the thigh were found in the basin of the sciatic and posterior arteries, the lowest — in the basin of the deep femoral artery and popliteal artery. On the shin, the highest rates of microcirculation were found in the basin of the posterior tibial artery, the lowest - on the foot. Results and discussion. The level of regional perfusion of the corresponding angiosomes of the skin of the lower extremities after anastomosis between the anterior tibial artery and anterior tibial vein showed that the improvement of microcirculation is observed in those angiosomes whose blood supply is provided by the anterior tibial artery and its artery and artery. When creating anastomoses between the posterior tibial artery and the posterior tibial vein, the microcirculation in the skin increased 3-5 times compared to baseline and its level was 70 % of normal in those angiosomes, which supply blood to the posterior tibial artery and its continuation on the foot. At the same time, there is an increase in skin microcirculation in the angiosome of the tibial artery, which is apparently due to the presence of a relatively large number of first-type anastomoses in the triceps. In our opinion, any of the proposed treatments should begin before the development of critical ischemia. Conclusions. The dependence of skin perfusion on the main arterial blood flow is proved taking into account the angiosomal theory, which allows to use this method in the diagnosis and evaluation of the results of treatment of chronic critical ischemia of the lower extremities. Microcirculation of the skin of the lower leg and foot improves 3.5–5 times 30 days after the creation of arteriovenous fistula below the occlusion of the anterior tibial artery and posterior tibial artery in chronic critical ischemia of the lower extremities.

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.

Enhanced External Counterpulsation

Objective: This study aimed to investigate acute hemodynamics of lower extremities during enhanced external counterpulsation with a three-level sequence at the hips, thighs, and calves (EECP-3), two-level sequence at the hips and thighs (EECP-2), and single leg three-level sequence (EECP-1).Methods: Twenty healthy volunteers were recruited in this study to receive a 45-min EECP intervention. Blood flow spectrums in the anterior tibial artery, posterior tibial artery, and dorsalis pedis artery were imaged by Color Doppler ultrasound. Mean flow rate (FR), area, pulsatility index (PI), peak systolic velocity (PSV), end-diastolic velocity (EDV), mean flow velocity (MV), and systolic maximum acceleration (CCAs) were sequentially measured and calculated at baseline during EECP-3, EECP-1, and EECP-2.Results: During EECP-3, PI, PSV, and MV in the anterior tibial artery were significantly higher, while EDV was markedly lower during EECP-1, EECP-2, and baseline (all P < 0.05). Additionally, ACCs were significantly elevated during EECP-3 compared with baseline. Moreover, FR in the anterior tibial artery was significantly increased during EECP-3 compared with baseline (P = 0.048). During EECP-2, PI and MV in the dorsalis pedis artery were significantly higher and lower than those at baseline, (both P < 0.05). In addition, FR was markedly reduced during EECP-2 compared with baseline (P = 0.028). During EECP-1, the area was significantly lower, while EDV was markedly higher in the posterior tibial artery than during EECP-1, EECP-2, and baseline (all P < 0.05). Meanwhile, FR of the posterior tibial artery was significantly reduced compared with baseline (P = 0.014).Conclusion: Enhanced external counterpulsation with three-level sequence (EECP-3), EECP-2, and EECP-1 induced different hemodynamic responses in the anterior tibial artery, dorsalis pedis artery, and posterior tibial artery, respectively. EECP-3 acutely improved the blood flow, blood flow velocity, and ACCs of the anterior tibial artery. In addition, EECP-1 and EECP-2 significantly increased the blood flow velocity and peripheral resistance of the inferior knee artery, whereas they markedly reduced blood flow in the posterior tibial artery.

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.

AbstractAnterior tibial artery is a nonvital artery which is one of the three arteries of the leg. This artery has a short proximal l segment in the popliteal region and a long segment in the anterior compartment of the leg designated as distal segment. With consideration of the deep location of the proximal segment in the popliteal fossa, it is less susceptible to trauma and subsequent formation of an aneurysm. On the contrary, the superficial long distal segment is more susceptible to trauma with high chance of pseudoaneurysm formation at the site of unrecognized injury. In this article, a 38-year-old military man being manifested about a decade after a trivial missile fragment injury with progressive posterior tibial neuropathy is presented. A giant pseudoaneurysm arising from the proximal segment of the anterior tibial artery was confirmed with angiography and the exact size of this pathology was documented with contrasted computed tomographic scan. The aneurysmal sac removal was accomplished after ligation of the corresponding artery proximal and distal to the sac followed by tibial nerve neurolysis which result in full recovery. In careful review we found that neither pseudoaneurysm arising from the proximal tibial artery nor posterior tibial neuropathy due to the compressive effect of the aneurysmal sac of this segment has been reported previously. Our primary purpose for reporting this case is not to describe the rarity of pseudoaneurysm formation at proximal segment of this artery but rather to describe delayed-onset posterior tibial vascular compressive neuropathy due to such an aneurysm. Eventually due to the potential sequel of a pseudoaneurysm, it is important for the surgeons to have high index of suspicion to prevent a missed or delayed diagnosis.
