[Coverage of an infected Deep femoral arteria vascular graft bypass by pediculated chimeric antero- lateral thigh flap associated with a vastus lateral muscle]. / Couverture d'un pontage par allogreffe de l'artère fémorale profonde par un lambeau pédiculé chimérique antérolatéral de cuisse associé au muscle vaste latéral.

Scarpa triangle defects with exposure of femoral bypass are challenging to treat. The authors present the case of a 46 years-old male with a groin defect of 10×18cm with an exposure on 5cm of an allograft of the deep femoral artery. Bypass was performed in emergency because of a limb ischemia with deep femoral artery thrombosis and aneurysm of the superficial femoral artery. The reconstructive surgery may propose a large musculo-cutaneous flap to fill the dead spaces surrounding the infected bypass, the flap should be vascularized by the deep femoral arteria, could not be the rectus abdominals flap because of the precedent abdominal incision. The homolateral pediculated ALT-flap with vastus lateral component appeared to be a good solution because of its versatility and the low morbidity of the donor site.

Textile Aging Characterization on New Generations of Explanted Commercial Endoprostheses: A Preliminary Study.

OBJECTIVE/BACKGROUND: The goal of the present study was to assess the aging phenomena on second-generation textile endoprostheses (EPs) through explant analysis and to establish a preliminary classification of observed defects and material damages. METHODS: From January 2011 to June 2016 110 second- and recent-generation EPs were collected as a part of a European collaborative retrieval program. The analysis focused on the first 41 consecutive commercial EPs collected between 2011 and 2014 and made from polyethylene terephthalate. Explants were submitted to a standardized evaluation protocol, which included data recording, eye-naked evaluation, cleaning of organic remnants, and structural analysis under numerical optical microscopy. Observations were reported using a classification based on 15 features evaluating the fabric, the stitches between the fabric and the stents, and the stents. The total surface area of the holes within the fabric was measured. RESULTS: EPs were implanted for thoracic and abdominal procedures in 12 and 29 cases, respectively. The mean ± SD duration of implantation was 34 ± 26 months (range 2 days-8 years). Sixty-four percent of the samples demonstrated at least one defect caused by compression damage potentially related to the insertion of the EP within the delivery system, which promoted holes and tears. Ninety-five percent of all EPs demonstrated at least one type of abrasion on the stitches. The degradation of the stitches and the number of ruptures increased with duration of implantation. Stent degradation was rare and consisted of corrosion and rupture. Cumulated holed surface area increased with time and was measured up to 13.5 mm2. CONCLUSION: Various aging-related phenomena on commercial textile EPs were identified and classified. Main damaging mechanisms were related to compression and abrasion leading to tears and holes in the fabric and rupture of stitches.

Five Year Outcomes of Surgical Treatment for Popliteal Artery Entrapment Syndrome.

OBJECTIVE/BACKGROUND: The aim of this study was to evaluate long-term outcomes following surgery for popliteal artery entrapment syndrome. METHODS: A retrospective study of all patients that underwent surgery for popliteal artery entrapment syndrome between January 2003 and December 2009 was performed. Patient demographic data, clinical features, imaging modalities, and surgical management were recorded. The primary outcome was 5 year patency. RESULTS: Eighteen patients (25 limbs) underwent surgery. The mean age at the time of surgical procedure was 35 (median 35 years; range 15-49). Presentation was bilateral in seven patients (39%). Diagnosis was made using various imaging modalities, including position stress test, Duplex ultrasonography, computed tomography angiography, magnetic resonance imaging and conventional angiography. In four limbs the popliteal artery was compressed and undamaged (16%), and treatment consisted of musculo-tendinous division alone. In 16 limbs the popliteal artery was damaged with lesions limited to the popliteal artery (64%) where treatment consisted of venous interposition. In five limbs lesions extended beyond the popliteal artery (20%) and procedures included one below knee femoro-popliteal bypass, three femoro-posterior tibial bypasses, and one popliteo-posterior tibial bypass. Musculo-tendinous division was associated with vascular reconstruction in 19 limbs (90%). Mean follow up was 82 months (median 81 months, range 60-120). Five year patency was 84%. CONCLUSION: Long-term outcomes of surgical procedures performed for popliteal artery entrapment syndrome can be considered satisfactory.

Results of isolated infrapopliteal percutaneous transluminal angioplasty for critical limb ischemia in high-risk diabetic patients.

AIM: Infrapopliteal occlusive arterial lesions mostly characterize diabetic patients arteriopathy. Diabetic patients are prone to multiple comorbidities that make them candidates for low-invasive therapeutic options. The aim of this study was to evaluate the safety of infrapopliteal angioplasty in high-risk diabetic patients. METHODS: We undertook a study (retrospective study of a prospectively collected database) of all infrapopliteal endovascular revascularizations performed for critical limb ischemia in high-risk (≥3 major comorbidities) diabetic patients in our institution between 2008 and 2010. Study end points were safety, technical success rate, healing rate, overall 1-year survival, primary patency, secondary patency and limb salvage rates. RESULTS: A total of 101 high-risk diabetic patients (160 arterial lesions: 94 stenosis and 66 occlusions) underwent infrapopliteal endovascular surgery. No major adverse cardiovascular or cerebrovascular event was recorded within 30 days. Two major adverse limb events (two thromboses requiring major amputation) and seven minor adverse events were recorded. Technical and healing rates were, respectively, 83% and 78%. The 1-year survival, primary patency, secondary patency and limb salvage rates were, respectively, 86%, 67%, 83% and 84%. CONCLUSION: Infrapopliteal angioplasty can be considered as a safe and feasible option for high-risk diabetic patients with critical limb ischemia.

Chronic mesenteric ischemia: 20 year experience of open surgical treatment.

OBJECTIVES: Both open surgery (OS) and endovascular surgery (ES) have been proposed for the treatment of symptomatic chronic mesenteric ischaemia (CMI). OS was considered the gold standard but ES is increasingly proposed as the first option. The aim was to report long-term outcomes associated with OS in patients suffering CMI in the modern era in order to help in choose between the two techniques. MATERIALS AND METHODS: A retrospective single centre analysis of all consecutive digestive artery revascularizations performed for CMI between January 2003 and December 2012 was carried out. Primary outcomes were 30 day mortality and morbidity, and secondary outcomes were survival, primary patency (PP), secondary patency (SP), and freedom from digestive symptoms, depending on the completeness of the revascularization performed. RESULTS: Eighty-six revascularizations were performed. Median follow up was 6.9 years (range 0.3-20.0). The 30 day mortality and morbidity rates were respectively 3.5% and 13.9%. Ten year survival was 88% for complete revascularization (CR) and 76% for incomplete revascularization (IR) (p = .54). The PP was 84% at 10 years for CR and 87% respectively for IR (p = .51). The 10 year SP was 92% for CR and 93% for IR (p = .63). Freedom from digestive symptoms was influenced by the completeness of revascularization: 79% for CR versus 65% for IR at 10 years (p = .04). CONCLUSIONS: OS for CMI, especially complete revascularization, provides lasting results despite high morbidity.

Gender related Long-term Differences after Open Infrainguinal Surgery for Critical Limb Ischemia.

OBJECTIVE: The role of gender on long-term infrainguinal open surgery outcomes still remains uncertain in critical limb ischemia patients. The aim of this study is to evaluate the gender-specific differences in patient characteristics and long-term clinical outcomes in terms of survival, primary patency and limb salvage among patients undergoing infrainguinal open surgery for CLI. MATERIAL AND METHODS: All consecutive patients undergoing infrainguinal open surgery for critical limb ischemia between 2003 and 2012 were included. Survival, limb salvage and primary patency rates were assessed. Independent outcome determinants were identified by the Cox proportional hazard ratio using age and gender as adjustment factors. RESULTS: 584 patients (269 women and 315 men, mean age 76 and 71 years respectively) underwent 658 infrainguinal open surgery (313 in women and 345 in men). Survival rate at 6 years was lower among women compared to men with 53.5% vs 70.9% (p < 0.001). The same applied to primary patency (35.9% vs 52.4%, p < 0.001) and limb salvage (54.3% vs 81.1%, p < 0.001) at 6 years. Female-gender was an independent factor predicting death (hazard ratio 1.50), thrombosis (hazard ratio 2.37) and limb loss (hazard ratio 7.05) in age and gender-adjusted analysis. CONCLUSION: Gender-related disparity in critical limb ischemia open surgical revascularization outcomes still remains.

A new murine model of sustainable and durable chronic critical limb ischemia fairly mimicking human pathology.

OBJECTIVE: To establish a chronic mouse model of critical limb ischemia (CLI) with in vivo and ex vivo validation, closely mimicking human pathology. METHODS: Swiss mice (n = 28) were submitted to sequential unilateral femoral (day 0) and iliac (day 4) ligatures. Ischemia was confirmed by clinical scores (tissue and functional damages) and methoxyisobutylisonitrile (MIBI) scintigraphies at days 0, 4, 6, 10, 20, and 30. At days 10, 20, and 30, muscle mitochondrial respiration, calcium retention capacity (CRC), and production of reactive oxygen species (ROS) were investigated, together with transcripts of mitochondrial biogenesis and antioxidant enzymes. Histological analysis was also performed. RESULTS: Clinical and functional damage confirmed CLI. MIBI scintigraphies showed hypoperfusion of the ischemic limb, which remained stable until day 30. Mitochondrial respiration was impaired in ischemic muscles compared with controls (Vmax = 7.93 ± 0.99 vs. 10.09 ± 2.87 mmol/L O2/minute/mg dry weight [dw]; p = .01), together with impaired CRC (7.4 ± 1.6 mmol/L minute/mg dw vs. 11.9 ± 0.9 mmol/L minute/mg dw; p < .001) and biogenesis (41% decrease in peroxisome proliferator-activated receptor gamma coactivator [PGC]-1α, 49% decrease in PGC-1ß, and 41% decrease in nuclear respiratory factor-1). Ischemic muscles also demonstrated increased production of ROS under electron paramagnetic resonance (0.084 ± 0.029 vs. 0.051 ± 0.031 mmol/L minute/mg dw; p = .03) and with dihydroethidium staining (3622 ± 604 arbitrary units of fluorescence vs. 1224 ± 324; p < .01), decreased antioxidant enzymes (32% decrease in superoxide dismutase [SOD]1, 41% decrease in SOD2, and 49% decrease in catalase), and myopathic features (wider range in fiber size, rounded shape, centrally located nuclei, and smaller cross-sectional areas). All defects were stable over time. CONCLUSION: Sequential femoral and iliac ligatures closely mimic human functional, clinical, scintigraphic, and skeletal muscle mitochondrial characteristics, and could prove useful for testing therapeutic approaches.

Poor long-term stability of the Corvita abdominal stentgraft.

INTRODUCTION: The endovascular treatment of abdominal aortic aneurysms was introduced in the early 1990s, with different generations of devices using various options for either the stent skeleton or the membrane. REPORT: Corvita generated one of these devices using braided stainless steel and a porous spun polycarbonate urethane membrane. DISCUSSION: In this report, we describe a case involving Corvita stentgraft explantation for complete aneurysm reperfusion after 13 years, demonstrating major degradation of the polyurethane membrane.

Methylene blue protects liver oxidative capacity after gut ischaemia-reperfusion in the rat.

OBJECTIVES: Mesenteric ischaemia/reperfusion (IR) may lead to liver mitochondrial dysfunction and multiple organ failure. We determined whether gut IR induces early impairment of liver mitochondrial oxidative activity and whether methylene blue (MB) might afford protection. DESIGN: Controlled animal study. MATERIALS AND METHODS: Rats were randomised into three groups: controls (n = 18), gut IR group (mesenteric ischaemia (60 min)/reperfusion (60 min)) (n = 18) and gut IR + MB group (15 mg kg(-1) MB intra-peritoneally) (n = 16). Study parameters were: serum liver function markers, blood lactate, standard histology and DNA fragmentation (apoptosis) on intestinal and liver tissue, maximal oxidative capacity of liver mitochondria (state 3) and activity of complexes II, III and IV of the respiratory chain measured using a Clark oxygen electrode. RESULTS: Gut IR increased lactate deshydrogenase (+982%), aspartate and alanine aminotransferases (+43% and +74%, respectively) and lactate levels (+271%). It induced segmental loss of intestinal villi and cryptic apoptosis. It reduced liver state 3 respiration by 30% from 50.1 ± 3 to 35.2 ± 3.5 µM O(2) min(-1) g(-1) (P < 0.01) and the activity of complexes II, III and IV of the mitochondrial respiratory chain. Early impairment of liver mitochondrial respiration was related to blood lactate levels (r(2) = 0.45). MB restored liver mitochondrial function. CONCLUSIONS: MB protected against gut IR-induced liver mitochondria dysfunction.

Autonomy following revascularisation in 80-year-old patients with critical limb ischaemia.

OBJECTIVES: We wanted to compare autonomy recovery after open and endovascular infrainguinal surgery for critical limb ischaemia (CLI) in octogenarians. MATERIALS AND METHODS: We performed a retrospective analysis of 167 consecutive CLI octogenarians who underwent infrainguinal open surgery (OS) or endovascular surgery (ES) between 2003 and 2008. OS and ES groups were compared in terms of autonomy level (Parker score), survival, limb salvage and patency rates. RESULTS: Preoperative autonomy level was similar in both groups (OS n = 109, ES n = 58) but 6-month postoperative autonomy level was better after ES (p = 0.01). There was a trend towards better survival after OS (74% at 1 year, 62% at 2 years, 32% at 4 years with OS and 68%, 50%, 17% respectively for ES p = 0.06), but no difference regarding limb salvage (91% at 1 year, 90% at 2 years, 89% at 4 years for OS and 94%, 87%, 86% respectively for ES, p = 0.939) and primary patency (76% at 1 year, 59% at 2 years, 50% at 4 years for OS and 82%, 75%, 32% respectively for ES, p = 0.467). CONCLUSIONS: ES is justified in CLI octogenarians, because it allows restoring a higher autonomy level, with limb salvage and patency rates comparable to OS.

Local but not systemic capillary lactate is a reperfusion biomarker in experimental acute limb ischaemia.

INTRODUCTION: Systemic capillary lactate, an end product of cellular anaerobic metabolism, has not established credibility in monitoring limb reperfusion. We assessed, in mice, whether local capillary lactate, arising from the reperfused limb, might be a relevant biomarker of reperfusion. REPORT: Systemic and local capillary lactate were sampled in the non-ischaemic and in the ischaemic limb. Only local lactate concentrations significantly increased after 2 h of ischaemia and decreased after reperfusion. DISCUSSION: Local, but not systemic, capillary lactate appeared as a potential reperfusion biomarker in this experimental acute limb ischaemia model.

Endovascular treatment of infra-popliteal arteries in patients with critical limb ischemia.

Currently, critical limb ischemia occurs in an ageing population with more and more diabetic patients and infra-popliteal lesions. In order to be as little invasive as possible, endovascular techniques have been proposed as one of the best options for these patients. In the following review, we present the specificities and assess the clinical effectiveness of endovascular treatment for infra-popliteal lesions in critical limb ischemia. We undertook a literature review based on publications dealing with critical limb ischemia and infra-popliteal endovascular treatment and published during the last decade. All relevant studies were systematically reviewed. The recorded outcomes were: immediate technical success, peri-operative complications, 30-day mortality, primary and secondary patency, limb salvage, and patient survival. Thirty-one studies including a total of 3164 patients (range: 13 to 993) were included in this review. Technical success rates ranged between 72% and 100%. Peri-operative complications rates ranged between 0% and 16%, most complications being considered as minor. 30-day mortality rates ranged between 0% and 5%. Primary, secondary patency and limb salvage rates were respectively about 60%, 65%, and 85%. One-year survival was about 80%. In conclusion, endovascular treatment can be considered as a good option for the treatment of infra-popliteal lesions in critical limb ischemia. Despite the non entirely satisfactory patency rates, endovascular treatment may provide wound healing and limb salvage.

Secondary rupture of abdominal aortic aneurysm following endovascular repair.

AIM: The aim of this study was to analyze the Literature covering the characteristics of secondary ruptured abdominal aortic aneurysm (AAA) following endovascular repair with aortic stent graft (ASG). METHODS: The study based on a Pubmed search of articles describing the characteristics of secondary ruptured AAA after ASG between January 1995 and May 2008. A total of 105 articles were selected, including the following characteristics: aneurysm diameter evolution, delay between implantation and rupture, average follow-up time, mechanisms implicated, results following further repair. RESULTS: Out of a total of 23 002 ASG cases reported, of which 47.4% (10 911) were carried out by ASG suppliers themselves, 227 ruptures (1%) have been described. After exclusion of the perioperatory ruptures (occurring within the first month), the average duration of implantation at rupture was 27+/-16 months, with an average follow-up of 22.4+/-14 months. When the evolution of the sac was mentioned, AAA diameter decreased or remained stable before rupture in 55.7% of the cases. Mechanisms of rupture have been reported in 168 cases and consisted in a failure of the ASG in 76.1% of the cases. When patients were operated, the mortality rate was 39%. CONCLUSION: This study showed how little is actually known about rupture of stented AAA. The available data were provided by studies sponsored by companies in 47.4% of the cases, and had usually too short follow-up considering the average of duration of implantation at rupture. Rupture mechanisms were not reported in all cases, but a failure of the ASG was considered as responsible for the rupture in a majority of the cases. The absence of warning signs of rupture emphasizes the need of caution about the durability of ASG and also the need to undertake further studies with longer follow-ups.

[Current clinical applications of vacuum-assisted closure (VAC) in vascular surgery]. / Pratique clinique du vacuum-assisted closure (VAC) en chirurgie vasculaire.

The aim of the study was to evaluate the efficacy of vacuum-assisted closure (VAC) in vascular patients presenting limb ulcers or non healed amputations. The efficacy of the VAC was studied in terms of healing, walking distance, and autonomy of life. This retrospective study included 14 patients, 11 men and three women, who were treated by a VAC therapy between December 2003 and February 2007. Two patients presented critical ischemia with limb ulcers and 12 patients non healed amputations despite previous revascularisation. Vascular reconstruction was performed in all cases before the VAC therapy. The rate of wound healing with VAC therapy was 87%. After wound healing, 92% of patients were walking and 62% of them were independent. In conclusion, VAC therapy may be a useful tool to accelerate healing of lower-limb wounds or non healing wounds secondary to amputation, allowing a faster recovery with a good level of autonomy.

[Mortality and morbidity of consecutive surgical carotid revascularisations in octogenarians]. / Mortalité et morbidité d'une série consécutive de revascularisations chirurgicales carotidiennes chez l'octogénaire.

AIM OF THE STUDY: Retrospective evaluation of the immediate and mid term mortality and morbidity of carotid surgical revascularisations in a population of octogenarians with severe carotid artery stenosis. MATERIAL AND METHOD: Retrospective study of all patients 80 years old and more, consecutively operated for an internal carotid artery stenosis, from January 1991 to December 2003, in the Unit of Vascular Surgery of the Civil Hospices of Strasbourg. We analyzed the perioperative death and stroke rates at 30 days and the mid term survival. RESULTS: We performed 81 carotid revascularisations on 70 patients. The mean age of the population studied was 83.5 (+/-2.8 years), (range 80-92). Twenty-four stenoses (29.6%) were symptomatic (23 transient ischemic accidents, 1 stroke), and 57 stenoses (70.4%) were asymptomatic. The mean degree of stenosis was 89.2+/-8.1% (based on NASCET evaluation). The main cardiovascular risk factor was arterial hypertension (95.7%). The overall perioperative death and stroke rate was 7.1%: 2 deaths, one of them related to a stroke, and 3 strokes (confidence interval: 2.4-15.9%). The perioperative death and stroke rate in the symptomatic stenosis group was 0%, and 8.8% in the asymptomatic stenosis group (p=0.163). No specific risk factor of neurologic events has been found except ASA 3 or higher (RR: 3.84 [1.2-12.1]). The mean follow up was 3.6 years (range 2-11.3), no patient was lost to follow-up. The Kaplan-Meier 5-year survival was 52%. The mean time to death was 3.5 years after the operation. Only 16.7% of these deaths were stroke-related. CONCLUSIONS: Multicentric prospective studies, which have determined current recommendations for carotid surgery, did not include patients aged 79 years and older. In this particular population, the good results observed in our institution in the symptomatic carotid stenosis group would support the use of surgical treatment. The perioperative death and stroke rate observed for the asymptomatic group, clearly superior to current recommendations, suggests in our experience and especially for ASA> or =3, an individual evaluation to determinate the best indication.

[Skeletal muscle ischemia-reperfusion and ischemic conditioning pathophysiology-clinical applications for the vascular surgeon]. / Physiopathologie de l'ischémie-reperfusion et du conditionnement ischémique du muscle squelettique ­ applications cliniques pour le chirurgien vasculaire.

Ischemia-reperfusion, which is characterized by deficient oxygen supply and subsequent restoration of blood flow, can cause irreversible damage to tissue. The vascular surgeon is daily faced with ischemia-reperfusion situations. Indeed, arterial clamping induces ischemia, followed by reperfusion when declamping. Mechanisms underlying ischemia-reperfusion injury are complex and multifactorial. Increases in cellular calcium and reactive oxygen species, initiated during ischemia and then amplified upon reperfusion are thought to be the main mediators of reperfusion injury. Mitochondrial dysfunction also plays an important role. Extensive research has focused on increasing skeletal muscle tolerance to ischemia-reperfusion injury, especially through the use of ischemic conditioning strategies. The purpose of this review is to focus on the cellular responses associated with ischemia-reperfusion, as well as to discuss the effects of ischemic conditioning strategies. This would help the vascular surgeon in daily practice, in order to try to improve surgical outcome in the setting of ischemia-reperfusion.

[Contribution of mathematical models and biomechanical properties in predicting the risk of abdominal aortic aneurysm rupture]. / Apport des modèles mathématiques et des études biomécaniques dans la prédiction du risque de rupture des anévrysmes de l'aorte abdominale.

INTRODUCTION: Rupture is the worst outcome of abdominal aortic aneurysm (AAA). The decision to operate should include counterbalancing the risk of aneurysm rupture against the risk of aneurysm repair, within the context of a patient's overall life expectancy. Current surgical guidelines are based on population studies, and important variables are missed in predicting individual risk of rupture. METHODS: In this literature review, we focused on the contribution of biomechanical and mathematical models in predicting risk of AAA rupture. RESULTS: Anatomical features as diameter asymmetry and lack of tortuosity are shown to be anatomical risk factors of rupture. Wall stiffness (due to modifications of elastin and collagen composition) and increased inflammatory response are also factors that affect the structural integrity of the AAA wall. Biomechanical studies showed that wall strength is lower in ruptured than non-ruptured AAA. Intra-luminal thrombus also has a big role to play in the occurrence of rupture. Current mathematical models allow more variables to be included in predicting individual risk of rupture. CONCLUSION: Moving away from using maximal transverse diameter of the AAA as a unique predictive factor and instead including biological, structural and biomechanical variables in predicting individual risk of rupture will be essential in the future and will help gain precision and accuracy in surgical indications.

[Pre- and postoperative imaging of type B aortic dissection]. / Imagerie de la dissection aortique de type B : ce que veut savoir le chirurgien avant et après l'intervention.

Type B aortic dissections are serious diseases with a 60 to 80 % 5-year survival rate. Although typically managed with a medical treatment, surgery may be necessary in the acute/subacute or the chronic phase if significant complications are encountered. For these patients, CT angiography is the first-line imaging modality, used for indicating and preparing the surgical procedure as well as for follow-up. Physicians in charge of these patients should be familiar with the key reading points. Visceral malperfusion is the most common acute complication, while aneurysmal dilatation of the false lumen is the most common chronic complication, with surgical management generally indicated when the axial diameter of the aorta exceeds 55mm. Endovascular treatment tends to replace open surgery: it requires precise measurements and identification of the entry tear (contribution of 4D-MRA).

[An atypical discipline: surgery in bullfighting. Two case reports]. / Une discipline atypique: la chirurgie taurine. A propos de deux observations.

Many bullfighters had been seriously injured, even sometimes killed during the fight in the bullring (around 300 deaths since the beginning of the 20th century). There is no comparison between bullfight's traumas and civil or war traumas, so only specialized medicine doctors and surgeons can be involved for practising. Surgery of bullfighting is a single speciality. The bullfight's surgeon in safekeeping will operate immediately in the bullfight place's infirmary and will aim at reducing the deep effect of horn injury. In this work, authors point out the bullfight pathology's complexity and its surgical treatment by presenting two original cases.

Current optimal morphological evaluation of peripheral arterial diseases.

Imaging plays a central role in the management of peripheral arterial diseases (PAD), emphasized by the continuously increasing use of modern cross-sectional imaging and the corresponding decline of digital subtraction angiography (DSA) in the diagnostic setting. Imaging is sometimes used as a screening tool in high-risk individuals. In symptomatic patients, imaging is mandatory to make an accurate positive diagnosis, grade the severity and the extent of the abnormalities, carefully choose and plan the best therapeutic option and provide adequate follow-up. Non-invasive diagnosis of PAD can be made by Doppler ultrasonography, magnetic resonance angiography (MRA) and computed tomography angiography (CTA). Given the major technological breakouts over the last decade, MRA and especially CTA are nowadays mature and precise enough to properly answer all the questions raised in symptomatic patients. This review article aims at describing state-of-the-art non-invasive imaging of PAD, its involvement in the decision-making for the vascular surgeon and the future trends and developments expected in the coming years.
