Rotational Mechanical Thrombectomy to Treat Iliac Limb Occlusion after Endovascular Aortic Aneurysm Repair: The Rotational Mechanical Thrombectomy Italian Study.

PURPOSE: To assess the safety and effectiveness of a rotational mechanical atherothrombectomy device in patients with symptomatic iliac limb occlusion after abdominal endovascular aneurysm repair (EVAR). MATERIALS AND METHODS: A retrospective analysis was conducted on patients who underwent rotational mechanical thrombectomy using the Rotarex S device for symptomatic acute, subacute, or chronic graft limb thrombosis at 5 vascular centers between 2017 and 2021. This study comprised 23 male patients with a mean age of 74.5 years (SD ± 7.2) at the time of the procedure. The clinical presentation of the patients varied, with 1 patient experiencing acute limb ischemia and 11 patients (47.8%) experiencing disabling intermittent claudication. The remaining patients developed chronic limb-threatening ischemia after iliac limb occlusion. Early outcomes included technical success, postprocedural complications, and periprocedural mortality. Follow-up evaluations encompassed primary patency, patient survival, freedom from reintervention, and the need for surgical conversion. RESULTS: Technical success was achieved in all cases, with no occurrences of distal embolization during or after the procedure, and no periprocedural deaths were reported. Endograft relining was performed in 82.6% of patients to establish a new, nonthrombogenic surface within the graft. Over a median follow-up period of 8 months (interquartile range, 3-16 months), 2 patients experienced iliac limb reocclusion. No deaths or other reinterventions occurred during the observational follow-up period. CONCLUSIONS: Rotational mechanical thrombectomy for iliac limb occlusion after EVAR appears to be both safe and effective. This technique may uncover intraluminal defects contributing to graft occlusion and enable their resolution within the same procedure.

Evidence of greater severity of diabetic foot ulcers during COVID-19 pandemic: A real-life single-centre cohort study.

AIMS: In the Sars-Cov-2 pandemic era, patients with diabetes mellitus (DM) manifested more severe forms of Sars-Cov-2 with greater mortality than non-diabetic patients. Several studies documented more aggressive forms of diabetic foot ulcers (DFU) during the pandemic period even though the results were not unanimously confirmed. The aim of this study was to evaluate the clinical-demographic differences between a cohort of Sicilian diabetic patients hospitalised for DFU in the pre-pandemic 3 years and a cohort of patients hospitalised in the pandemic 2 years. MATERIALS AND METHODS: One hundred and eleven patients from the pre-pandemic period 2017-2019 (Group A) and 86 patients from the pandemic period 2020-2021 (Group B) with DFU, admitted to the division of Endocrinology and Metabolism of the University Hospital of Palermo, were retrospectively evaluated. The clinical assessment of the type, staging and grading of the lesion, and the infective complication from DFU was performed. RESULTS: No differences in HbA1c values were observed between the two groups. Group B showed a significantly higher prevalence of male subjects (p = 0.010), neuro-ischaemic ulcers (p < 0.001), deep ulcers with involvement of bones (p < 0.001), white blood count levels (p < 0.001), and reactive C protein (p = 0.001) compared to group A. CONCLUSIONS: Our data show that in the COVID-19 pandemic, a greater severity of ulcers requiring a significantly greater number of revascularisations and more expensive therapy, but without an increase in the amputation rate, was observed. These data provide novel information on the impact of the pandemic on diabetic foot ulcer risk and progression.

A Multicenter Experience of Three Different "Iliac Branched" Stent Grafts for the Treatment of Aorto-Iliac And/Or Iliac Aneurysms.

BACKGROUND: The aim of study was to assess the safety and effectiveness of 3 different commercial iliac branch devices (IBDs): the Zenith Branch Iliac Endovascular Graft; the Gore Excluder Iliac Branch System and the E-liac Stent Graft System for the treatment of aorto-iliac or iliac aneurysms. METHODS: From January 2017 to February 2020, a retrospective reviewed was conducted on a total of 96 patients. Primary endpoint was IBD instability rate at 24 months. Secondary endpoints included onset of any endoleaks, buttock claudication, IBD-related reintervention and all-death rates, postoperative acute kidney, and changes in maximum diameter from baseline of the aortic aneurysmal sac. RESULTS: At 24 months, the branch instability rate was similar among the 3 IBDs employed [Jotec 1/24 (4.1%), Gore 1/12 (8.3%), Cook 6/47 (12.7%), P-value = 0.502]. As well, no statistical difference in terms of branch occlusion and branch-related endoleaks was observed. The Jotec group showed a significant decrease in maximum diameter from the baseline of the aortic aneurysmal sac when compared to the Gore group alone. No other differences were found relevant to the onset of any endoleaks, reinterventions, and all-death rates. At 24 months, the Kaplan-Meier estimate of survival freedom from any branch instability was 95.8%, 91.6%, and 86.8% for Jotec, Gore and Cook groups, respectively. CONCLUSIONS: The use of IBDs represents a safe method for preserving patency of the IIA during treatment of aorto-iliac or iliac aneurysms providing a low rate of IBD instability.

Outcome Analysis From a Multicenter Registry on Unibody Stent-Graft System for the Treatment of Spontaneous Infrarenal Acute Aortic Syndrome (MURUSSIAS Registry).

PURPOSE: This study reports the outcomes from a Multicenter Registry on unibody stent-graft system for the treatment of spontaneous infrarenal acute aortic syndrome (MURUSSIAS registry). MATERIALS AND METHODS: The retrospective MURUSSIAS registry included spontaneous infrarenal acute aortic dissection (IAAS) managed with the unibody stent-graft system (AFX endovascular AAA system; Endologix Inc., Irvine, California) outside the current instruction for use. IAAS considered aortic dissection (AD), intramural hematoma (IMH), and penetrating aortic ulcer (PAU). Indications to IAAS treatment were symptoms, associated dilated abdominal aorta (>3 cm), rapidly-growing (>0.5 cm/6 months) aorta, IAAS disease progression. Measured results were technical success, early (within 30 days) and midterm outcomes (after 30 days), including mortality, complications, symptoms recurrence, type I/III endoleak occurrence, stent-graft patency, survival, and freedom from reintervention. The mean follow-up was 22.12 ± 17 months. RESULTS: The MURUSSIAS registry included 83 patients from 7 participating centers. IAAS indication to treatment were symptoms in 42 (51%). In 14 (17%) patients, the infrarenal aortic length was <80 mm, and in 28 (34%), the aortic bifurcation diameter was <16 mm. Technical success was 100%. Mortality occurred early in 1 (1%) and at the midterm in 3 (4%) patients. Complications occurred early in 10 (12%) patients (1 severe, 3 moderates, and 6 mild) and at midterm in 2 (2%) (2 moderate). No symptoms' recurrence or type I/III endoleaks were registered. The 36-month estimated survival and freedom from reinterventions were 89% and 92%, respectively. CONCLUSIONS: The MURUSSIAS registry is the largest collection of spontaneous IAAS managed endovascularly using the AFX endovascular AAA system. The IAAS peculiar anatomic features were fitted with the used technique with excellent results. This treatment strategy might be considered in IAAS unless specifically-designed endovascular solutions will be available also in the emergent setting. Further studies are required to assess the longer-term performances and the stability of the reported technique. CLINICAL IMPACT: The lack of specifically designed devices for infrarenal acute aortic syndrome (IAAS) disease remains an issue principally for its specific anatomic features. The MURUSSIAS registry retrospectively examined the outcomes of spontaneous IAAS treated using the unibody stent-graft system in a spontaneous national study; and reports the largest available data on this topic. The use of the unibody stent-graft system showed to fit the anatomic peculiarities of IAAS with excellent outcomes. This IAAS treatment strategy should be considered unless specifically designed endovascular solutions will be available.

Efficacy and one-year outcomes of Luminor® paclitaxel-coated drug-eluting balloon in the treatment of popliteal artery atherosclerosis lesions.

PURPOSE: Reporting outcomes with a new generation paclitaxel eluting balloon (Luminor®; iVascular, Vascular, S.L.U., Barcelona, Spain) in the popliteal district. Endovascular treatment of popliteal artery atherosclerotic disease is still debated without definitive evidences. METHODS: From January to June 2019, patients' data presenting popliteal artery atherosclerotic diseases and treated with the Luminor® (iVascular) drug eluting balloon (DEB) were prospectively collected. Critical limb ischemia (CLI) or severe claudication associated with popliteal artery stenosis >50% were the inclusion criteria. Measured outcomes were technical success, early and late results; including mortality, morbidity, symptoms recurrence, amputation, ankle-brachial index (ABI), survival, primary patency, secondary patency, freedom from restenosis. Median follow-up was 22.43 ± 4 (mean:21.58; IQR:20-24) months. RESULTS: Of the 33 included patients, 28 (85%) were diagnosed with CLI, with a mean preoperative run-off score of 5.39 (r:0-10; SD:3) and a chronic popliteal occlusion in 21 (64%). Technical success was achieved in all cases. Perioperative mortality was observed in 1 (3%) patient and perioperative complications in 2 (6%). During the follow-up were reported 2 symptoms recurrence; a significant ABI increase (0.57; IQR:0.41-0.47 vs. 0.69; IQR:0.50-0.67; P < 0.01); 1 (3%) major and 2 (6%) minor amputations. Estimated 24 months survival, primary patency, secondary patency, and freedom from restenosis were 97%, 96.9%, 100%, and 93.8% respectively. CONCLUSIONS: In this prospective study, the use of the Luminor® (iVascular) was safe and effective in addressing atherosclerotic popliteal artery lesions. Larger studies with longer term-outcomes are required to assess the durability of this device in the popliteal artery.

Position Paper on Young Vascular Surgeons Training of the Mediterranean Federation for the Advancing of Vascular Surgery (MeFAVS): State of the Art and Perspectives.

The Mediterranean Federation for the Advancing of Vascular Surgery (MeFAVS) was founded in 2018, with the aim to promote cooperation among vascular professionals within Mediterranean countries. Due to its prominent social and economic impact on national health systems, diabetic peripheral artery was selected as the very first topic to be investigated by the federation. In this second paper, different experiences from delegates of participating countries were shared to define common strategies to harmonize, standardize, and optimize education and training in the Vascular Surgery specialty.

Endovascular Treatment of Spontaneous and Isolated Infrarenal Acute Aortic Syndrome with Unibody Aortic Stent-Grafts.

INTRODUCTION: Spontaneous acute aortic syndrome (IAAS) is rarely localized in the infrarenal aorta. The endovascular approach is preferred over conventional open surgery with fewer complications. However, dedicated endovascular devices for IAAS treatment are unavailable. The aim was to report a large single-center experience using unibody stent-grafts to address IAAS. METHODS: From April 2016 to March 2019, a retrospective analysis of patients presenting spontaneous and isolated IAAS was performed. Patients addressed with the unibody stent-graft (AFX endovascular AAA system; Endologix Inc., Irvine, CA) were included in the study. Indications to IAAS treatment were persistent symptoms and/or dilated abdominal aorta (>3 cm). The measured outcomes were technical success; early outcomes (<30 days) including mortality, morbidity, symptoms recurrence, and endoleak occurrence; and late outcomes (>30 days) including mortality, symptoms recurrence, endoleak occurrence, stent-graft patency, and survival. Median follow-up was 23.77 ± 10 months. RESULTS: Twenty-one patients with IAAS were included. Indications to treatment were symptoms in 14 (67%) patients and dilated abdominal aorta in 7 (33%). Technical success was achieved in all cases. No perioperative mortality and 1 (4.8%) early femoral access complication was encountered. During the follow-up were registered 1 (4.8%) aortic unrelated death and 1 (4.8%) stent-graft limb stenosis. The 36 months estimated survival and freedom from reintervention were 92% (CI: 37-43; SE: 1.7) and 94% (CI: 37-44; SE: 1.7), respectively. CONCLUSIONS: The endovascular treatment of IAAS with unibody stent-graft (AFX endovascular AAA system; Endologix Inc.) is safe and effective with promising mid-term outcomes. The use of unibody stent-grafts expands the endovascular indication, despite the usual anatomic IAAS features. Larger studies with longer follow-up are required to validate the outcomes of the reported technique.

Endovascular Treatment of Spontaneous Internal Carotid Artery Dissection with Proximal Embolic Protection Device.

BACKGROUND: The aim of this study was to report the feasibility and outcomes with the endovascular treatment of spontaneous internal carotid artery dissections (ICADs) using a proximal embolic protection device (EPD). METHODS: This is a retrospective analysis of patients treated for spontaneous symptomatic ICAD using a proximal EPD from January 2017 to December 2018. Indication for treatment was the presence of neurologic symptoms. Early outcomes measured included technical success, perioperative mortality, and major cardiovascular or cerebrovascular complications. Late outcomes were recurrent neurologic symptoms, patency, and reinterventions. RESULTS: A total of 4 male patients with ICAD were included. A preoperative cerebral computed tomography positive for cerebral ischemic events was reported in all cases. In 3 patients, the neurologic symptoms consisted of a transient ischemic attack; the remaining patient presented an amaurosis fugax and aphasia. In 2 patients, ICAD was associated with a carotid significant stenosis. In all patients, the reported approach was feasible with no complications and complete anatomic dissection resolution. At a mean follow-up of 18 months, all stents are patent and no restenosis recurrence or complications were registered. CONCLUSIONS: The use of proximal EPDs allowed the treatment of ICAD under flow arrest, minimizing the risk of stroke during the endovascular maneuvers. Larger series are required to validate this treatment strategy.

Single-Center Experience and Preliminary Results of Intravascular Ultrasound in Endovascular Aneurysm Repair.

BACKGROUND: Intravascular ultrasound (IVUS) has been introduced as diagnostic adjunct to provide new insights into the diagnosis and therapy of vascular disease. Herein, we compared the outcomes of conventional endovascular aneurysm repair (EVAR) and EVAR with IVUS in patients presenting with infrarenal abdominal aortic aneurysm using a propensity-matched cohort. METHODS: From May 2013 to August 2017, 221 patients were retrospectively analyzed. Of that, 122 patients were eligible for inclusion and underwent propensity score matching. Perioperative mortality and morbidity, renal function impairment, endoleak incidence, mean contrast medium usage, operative time, radiation exposure (including fluoroscopy time, dose-area product [DAP], and digital subtraction angiography [DSA] runs), survival, and freedom from reintervention were the outcomes measured. RESULTS: After matching, 52 patients were included, 26 in the conventional EVAR group and 26 in the EVAR with IVUS group. No perioperative mortality or type I/III endoleak were registered. One perioperative lymphatic fistula and one iliac limb occlusion were observed. In the EVAR with IVUS group, a significant reduction of contrast medium (92 [vs. 51 ± 17] vs. 51 [20-68] mL; P = 0.003) and radiation exposure including fluoroscopy time (12 [9-16] vs. 20 [12-25] min; P = 0.001), DAP (15 [9-21] vs. 32 [16-44] G*cm2; P = 0.002), and DSA runs (2 [1-3] vs. 3 [2-4]; P = 0.04) was reported. No differences were observed in terms of glomerular filtration rate (86 [45-121] vs. 90 [38-117] mL/min; P = 0.14) and operation time (176 [124-210] vs. 179 [120-210]; P = 0.48). Survival at 36 months was 93% for standard EVAR and 92% for EVAR with IVUS (P = 0.845). Freedom from reintervention at 36 months was 85.5% in both the groups (P = 0.834). CONCLUSIONS: In this preliminary experience, the use of IVUS during EVAR was feasible with no registered postoperative complications. A significant reduction of contrast medium usage and radiation exposure was observed with the use of IVUS. The IVUS is an adjunctive tool to consider in the vascular surgeon armamentarium, especially in centers where advanced radiological tools of imaging fusion are not available.

Symptomatic Deep Femoral Artery Pseudoaneurysm Endovascular Exclusion. Case Report and Literature Review.

Deep femoral artery pseudoaneurysms (DFAPs) are rare and generally occur after penetrating trauma or surgical procedures. A 36-year-old obese man presented with pain in correspondence of the anterior-lateral thigh after 6 months from gunshot wound. Duplex and computed tomography (CT) showed a bilobed right DFAP (maximal diameter 12.9 cm). The patient was managed urgently, under local anesthesia, by placement in the distal DFA of a Viabahn 8 × 100-mm stent graft (W L Gore & Associates, Inc). The postoperative course was uneventful, and the 24-month CT showed regular stent-graft patency and 20-mm DFAP shrinkage. The literature review reported 8 cases of DFAPs; of these 6 were managed by endovascular mean (3 stent-graft implantations and 3 coil embolization). The remaining 2 cases were managed surgically (one of these after failed coil embolization). In conclusion, the use of covered stent graft was effective to treat a DFAP localized in the medium DFA. This tool allowed maintaining the native DFA patency and the preservation of its main branches.

Spontaneous symptomatic common carotid artery pseudoaneurysm: case report and literature review.

Spontaneous common carotid artery pseudoaneurysm (CCAP) is rare but potentially lethal disease. A 78-year-old man presented with pain in correspondence of right neck side and slight right eye ptosis. No previous surgery, trauma, or venous catheterizations in the neck region were reported. The computed tomographic angiography (CTA) showed a 4-cm saccular CCAP. The patient was managed emergently with surgical CCAP excision. At 6-month follow-up, the patient is neck pain-free with complete ptosis regression, and the CTA shows no pathologic findings. The literature review reported 7 cases of pseudoaneurysm of carotid district. All these cases were managed by surgical approach, and in 1 case, an endovascular embolization procedure was associated before. The CTA was used in all cases but angiography in only one. In these cases, the surgical repair with pseudoaneurysm evacuation is still the treatment of choice.

Endograft connector technique to treat popliteal artery aneurysm in a morbid obese patient.

Surgical repair of popliteal artery aneurysm in morbid obese patients poses additional challenges. We report a morbid obese patient who had a 59 mm right popliteal artery aneurysm which was successfully treated with the endograft connector technique. This technique was used to perform the distal anastomosis of the below-knee femoro-popliteal bypass. A 10 mm Dacron graft was used as a main graft bypass and an 11 mm/10 cm stentgraft as endograft connector. Following the respective tunnel of the Dacron graft, an end-to-side proximal anastomosis was performed at distal femoral artery. The aneurysm exclusion was obtained through a proximal and a distal ligation. Postoperative duplex showed adequate bypass patency. Knee x-rays demonstrated no signs of stent kinking/fractures. The postoperative course was uneventful and the patient was discharged home on fourth day post operative. The six-month computed tomography scan and the 12-month duplex control showed a patent bypass with no signs of stenosis.

Improved Ultrasound-Guided Balloon-Assisted Maturation Angioplasty Using Drug-Eluting Balloons in the First Autogenous Arteriovenous Fistula Procedure: Early Experience.

In patients with end-stage renal failure requiring hemodialysis, autogenous arteriovenous fistula (AVF) is preferred over tunneled dialysis catheters due to lower complications and costs. However, AVF maturation failure remains a common issue due to small vein size, multiple venipunctures, and other factors. Guidelines recommend using vessels of >2 mm for forearm AVFs and >3 mm for upper arm AVFs. This study investigates the use of intraoperative Doppler ultrasound (DUS)-guided Balloon-Assisted Maturation (BAM) with drug-eluting balloons (DEB) during initial AVF creation. Data from 114 AVF procedures, of which 27.2% underwent BAM, were analyzed. BAM was performed in 25 distal radio-cephalic and 6 proximal brachio-cephalic AVFs. With DUS guidance, vein stenosis was identified and treated using DEB. Technical success was achieved in all cases, with no early mortality. Early BAM-related complications were minimal, and no AVF thrombosis occurred. AVF maturation time was 15 days (SD: 3), and no further complications were reported during a mean follow-up of 10.38 months. Using BAM with DEB during AVF creation led to successful maturation and dialysis use without the need for secondary procedures. This study emphasizes the importance of identifying AVF failure risk early and utilizing DUS-guided procedures to enhance AVF outcomes. A more liberal use of intraoperative BAM could limit reinterventions in patients undergoing AVFs.

Outcome Analysis of Speed Gate Cannulation during Standard Infrarenal Endovascular Aneurysm Repair.

BACKGROUND: Endovascular aortic repair (EVAR) is generally performed with bi/trimodular stent-grafts requiring retrograde contralateral gate cannulation (CGC). In the case of tricky CGC, an increased EVAR procedural time and radiation exposure have been reported. Herein, we compare the outcomes of conventional CGC and CGC using the speed gate cannulation (SGC) technique in standard EVAR for a propensity-matched cohort. METHODS: A total of 371 patients were retrospectively analyzed. Inclusion criteria were fulfilled in 172 patients who underwent propensity score matching. Primary outcomes included operative time, CGC time, mean contrast medium, fluoroscopy time, and CGC fluoroscopy time. RESULTS: After matching, 78 patients were included in each group (SGC vs. standard). Primary outcomes registered a significant reduction in CGC time (4 [1-6] vs. 8 [6-14] min; p = 0.001) and fluoroscopy time (12 [9-16] vs. 17 [12-25] min). CONCLUSIONS: In this preliminary experiment, the use of SGC was feasible with no significant registered postoperative complications. A significant reduction in contrast medium usage, radiation exposure, and CGC time was observed with the use of SGC. SGC is a simple adjunctive technique, and its use should be considered in standard EVAR, especially in emergency scenarios, where time is of the essence.

Carotid Artery Disease in the Era of Biomarkers: A Pilot Study.

The intima-media thickness (IMT) and its irregularities or ulcerations in the common carotid artery (CCA) are useful tools as sentinel biomarkers for the integrity of the cardiovascular system. Total homocysteine and lipoprotein levels are the most commonly used elements in cardiovascular risk stratification. Duplex ultrasound (DUS), associated with serum biomarkers, can be used simply to assess the degree of atherosclerotic disease and cardiovascular risk. This study highlights the role of different kinds of biomarkers, showing their usefulness and potentiality in multi-district atherosclerotic patients, especially for early diagnosis and therapy effectiveness monitoring. A retrospective analysis performed from September 2021 to August 2022, of patients with carotid artery disease, was performed. A total of 341 patients with a mean age of 53.8 years were included in the study. The outcomes showed an increased risk of stroke in patients with significative carotid artery disease, nonresponsive to therapy, monitored through a series of serum biomarkers (homocysteine, C-reactive protein, and oxidized LDL). In this reported experience, the systematic use of DUS in association with the multiple biomarkers approach was effective for the early identification of patients at higher risk of disease progression or inefficient therapy.

Endovascular treatment of abdominal aortic anastomotic pseudoaneurysm. The experience of two centers.

INTRODUCTION: Abdominal aortic pseudoaneurysms are a rare but serious complication of aortic surgery. Treatment with traditional open surgery is associated with a high rate of perioperative mortality and morbidity. Endovascular treatment is less invasive and guarantees lower mortality and morbidity rates. The aim of this study was to evaluate the role of short-, medium- and long-term endovascular treatment of these pseudoaneurysms. MATERIALS AND METHODS: Over the past 10 years, 14 patients with abdominal aortic aneurysms, which developed after prior aortic surgery, underwent endovascular treatment involving implantation of an endoprosthesis at our institutions. Exclusion criteria were emergency treatment and suspicion of an infected prosthesis. A Cheatham-platinum covered stent mounted on a balloon catheter was implanted in one patient and self-expandable stent-graft in the other 13. No fenestrated or custom-made prostheses were used. RESULTS: The procedure had a 100% technical success rate. There was no postoperative mortality. Two type I endoleaks, observed at aortography at the end of the procedure, were not seen on the CT scan taken one month later. Three patients (21.4%) had major perioperative complications which consisted of early occlusion of a branch of the endoprosthesis, (treated with a femoro-femoral crossover bypass graft), a transient ischemic attack, and jaundice. The long-term mortality rate, at an average follow-up of 37.4 months, was 21.4%. None of the deaths was related to the procedure. CONCLUSIONS: Endovascular treatment of patients who develop anastomotic pseudoaneurysm after surgery of the abdominal aorta is safe and effective both in the short and long term. In our opinion it is the treatment of choice for this category of patients.

CT angiography for the assessment of EVAR complications: a pictorial review.

Endovascular aneurysm repair (EVAR) is a minimally invasive treatment proposed as an alternative to open repair in patients with abdominal aortic aneurysms. EVAR consists in a stent-graft placement within the aorta in order to exclude the aneurysm from arterial circulation and reduce the risk of rupture. Knowledge of the various types of devices is mandatory because some stents/grafts are more frequently associated with complications. CT angiography is the gold standard diagnostic technique for preprocedural planning and postprocedural surveillance. EVAR needs long-term follow-up due to the high rate of complications. Complications can be divided in endograft device-related and systemic complications. The purpose of this article is to review the CT imaging findings of EVAR complications and the key features for the diagnosis.

The Role of Early Revascularization and Biomarkers in the Management of Diabetic Foot Ulcers: A Single Center Experience.

Diabetic neuropathy and Peripheral Arterial Disease (PAD) are the main etiological factors in foot ulceration. Herein, we report our experience of diabetic foot ulceration (DFU) management, with an analysis of the relationship between the rate of lower extremity amputation, in persons with infected DFU, after revascularization procedures performed to prevent major amputation. This study highlights the role of different biomarkers, showing their usefulness and potentiality in diabetic foot ulcer management, especially for the early diagnosis and therapy effectiveness monitoring. A retrospective analysis, from September 2016 to January 2021, of diabetic patients presenting diabetic foot with DFU, was performed. All patients were treated with at least one vascular procedure (endovascular, open, hybrid procedures) targeting PAD lesions. Outcomes measured were perioperative mortality and morbidity. Freedom from occlusion, primary and secondary patency, and amputation rate were registered. A total of 267 patients, with a mean age of 72.5 years, were included in the study. The major amputation rate was 6.2%, minor amputation rate was 17%. In our experience, extreme revascularization to obtain direct flow reduced the rate of amputations, with an increase in ulcer healing.

Simultaneous Hybrid Treatment of Multilevel Peripheral Arterial Disease in Patients with Chronic Limb-Threatening Ischemia.

BACKGROUND: Hybrid treatments (HT) aim to reduce conventional open surgery invasiveness and address multilevel peripheral arterial disease (PAD). Herein, the simultaneous HT treatment in patients with chronic limb-threatening ischemia (CLTI) is reported. METHODS: Retrospective analysis, for the period from May 2012 to April 2018, of patients presenting multilevel PAD with CLTI addressed with simultaneous HT. The outcomes of these interventions were measured the following metrics: early technical successes (within 30 days following treatment) and late technical successes (30 days or more following treatment) and included mortality, morbidity symptoms recurrence, and amputation. Survival and patencies were estimated. The median follow-up was 43.77 months. RESULTS: In the 45 included patients, the HT consisted of femoral bifurcation patch angioplasty followed by an endovascular treatment in 38 patients (84.4%) and endovascular treatment followed by a surgical bypass in 7 patients (15.6%). Technical success was 100% without perioperative mortality. Eight (17.8%) patients presented early complications without major amputations. During the follow-up, seven (15.6%) deaths occurred and six patients (13.3%) experienced symptoms recurrence, with five of those patients requiring major amputation. An estimated survival time of 5 years, primary patency, and secondary patency was 84.4%, 79.2%, and 83.3% respectively. CONCLUSIONS: Hybrid treatments are effective in addressing patients presenting with multilevel PAD and CLTI. The common femoral artery involvement influences strategy selection. Larger studies with longer-term outcomes are required to validate the hybrid approach, indications, and results.

Simultaneous endovascular treatment of synchronous symptomatic acute type B aortic dissection and large infrarenal aortic aneurysm. Technical tips and case report.

INTRODUCTION: Data from the literature suggest that in patients with acute type B aortic dissection (ATBAD), associated with AAA, rupture risk is higher at the confluence tract than isolated lessions. Herein, we report a case of ATBAD and AAA managed with simultaneous intervention. CASE PRESENTATION: We report a complicated case of a symptomatic patient presenting with a type B aortic dissection and false lumen extension into superior mesenteric artery (SMA) with an infrarenal abdominal aortic aneurysm (AAA). Severe back pain and hypertension were the patient's initial complaints. This patient underwent endovascular repair with a thoracic and infrarenal aortic endograft. DISCUSSION: AAA rupture has been detected at admission in three-fourths of patients with ATBAD that extended to or involved a coexisting unoperated atherosclerotic aneurysms. Prompt surgical intervention is essential to deal with this dreadful aortic emergency. CONCLUSION: In our experience a totally endovascular solution to treat a complicated ATBAD plus AAA was a rapid solution with low invasivity, no complication and complete healing of patients.
