RESUMO

OBJECTIVE: Management of follow-up protocols after endovascular aortic repair (EVAR) varies significantly between centers and is not standardized according to sac regression. By designing an international expert-based Delphi consensus, the study aimed to create recommendations on follow-up after EVAR according to sac evolution. METHODS: Eight facilitators created appropriate statements regarding the study topic that were voted, using a 4-point Likert scale, by a selected panel of international experts using a three-round modified Delphi consensus process. Based on the experts' responses, only those statements reaching a grade A (full agreement ≥75%) or B (overall agreement ≥80% and full disagreement <5%) were included in the final document. RESULTS: One-hundred and seventy-four participants were included in the final analysis, and each voted the initial 29 statements related to the definition of sac regression (Q1-Q9), EVAR follow-up (Q10-Q14), and the assessment and role of sac regression during follow-up (Q15-Q29). At the end of the process, 2 statements (6.9%) were rejected, 9 statements (31%) received a grade B consensus strength, and 18 (62.1%) reached a grade A consensus strength. Of 27 final statements, 15 (55.6%) were classified as grade I, whereas 12 (44.4%) were classified as grade II. Experts agreed that sac regression should be considered an important indicator of EVAR success and always be assessed during follow-up after EVAR. CONCLUSIONS: Based on the elevated strength and high consistency of this international expert-based Delphi consensus, most of the statements might guide the current clinical management of follow-up after EVAR according to the sac regression. Future studies are needed to clarify debated issues.

RESUMO

OBJECTIVE: This study aimed to analyze early and midterm results of custom-made proximal scallop and fenestrated stent grafts for thoracic endovascular aortic repair (TEVAR) with a proximal landing zone (PLZ) in the aortic arch. METHODS: All consecutive patients treated with the custom made proximal scalloped and fenestrated Relay stent grafts (Terumo Aortic Bolton Medical Inc.) in 10 Italian centers between January 2014 and December 2022 were included. The primary end points were technical success, incidence of intraoperative major adverse events, deployment accuracy, and rate of early neurological complications, endoleaks (ELs) and retrograde aortic dissection. RESULTS: During the study period, 49 patients received TEVAR with Relay custom-made endograft in Italy were enrolled. The median patient age was 70.1 years (interquartile range, 23-86 years) and 65.3% were male. The indication for treatment was atherosclerotic aneurysms in 59.2% of cases and penetrating aortic ulcer in 22.4%. The endograft configuration was proximal fenestration in 55.1% and scallop in 44.9%. The proximal landing zone was zone 0 in 25 cases (51%), zone 1 in 14 cases (28.6%), and zone 2 in 10 cases (20.4%). The supra-aortic debranching procedures were 38 (77.5%). Technical success was 97.9% (48/49) owing to one case (2.0%) of inaccurate deployment. Intraoperatively, one (2.0%) type Ia and one (2.0%) type III EL were detected. There were no cases of in-hospital mortality, major adverse events, or retrograde dissection. Three minor strokes (6.1%) (National Institutes of Health Stroke Scale score of ≤4) were observed. At a mean follow-up time of 36.3 ± 21.3 months the rate of types I to III ELs and reintervention was 4.1%, respectively. Four patients (8.2%) died during the follow-up period, one (2.1%) from abdominal aortic rupture and three (6.1%) from nonaortic causes. CONCLUSIONS: Our early and midterm outcomes suggest that scalloped and fenestrated TEVAR may provide an acceptable alternative treatment option for aortic arch pathologies. Large-scale studies are needed to assess the long-term durability of this technique.

RESUMO

BACKGROUND: The use of biological grafts provides acceptable mid- and long-term results in native or prosthetic vascular infections. Several reports describe the successful use of bovine pericardium in case of vascular infections, mainly as a large patch to be sutured as a tubular graft. Recently, a novel prefabricated bovine pericardium graft (Biointegral Surgical No-React® Inc, Mississauga, ON, Canada) has been introduced in clinical practice with promising results. In this study, we report our preliminary experience utilizing Biointegral Surgical graft in case of native and or prosthetic aorto-iliac and infrainguinal infection. METHODS: We retrospectively analyzed data from 20 patients with native or prosthetic aorto-iliac and infrainguinal infection who underwent in situ reconstruction (ISR) with a Biointegral Surgical No-React bovine pericardium prosthesis between October 2020 and February 2023 at the Vascular Surgery Unit of the Fondazione Policlinico Universitario Gemelli - IRCCS in Rome, Italy. All patients followed a standardized protocol including postoperative anticoagulation and long-term intravenous antibiotics. RESULTS: The indication for surgery was: mycotic aortic aneurysm in 4 patients (20%), graft infection after abdominal aortic repair in 11 patients (55%), peripheral graft infection in 5 patients (25%). Complete excision of the infected aorta or prosthetic graft, surgical debridement and ISR were performed in all patients. Hospital mortality rate was 5% (n = 1) and graft-related mortality of 0%. During follow-up (median 13 months, range 6-34 months), reinfection was 5.2% and primary graft patency 94.7%. CONCLUSIONS: The use of prefabricated bovine pericardial grafts represents a promising option for the treatment of native and prosthetic aorto-iliac and infrainguinal infections. The application of this biological graft with a standardized postoperative protocol has been associated with a satisfactory patency and reinfection rate without increased bleeding complications.

RESUMO

OBJECTIVE: Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset. METHODS: Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders. We report the early and mid-term clinical outcomes including stroke and mortality, technical success, and other operative outcomes including reintervention rates, patency, and endoleak. RESULTS: Overall, 285 patients were identified during the study period. The mean patient age was 57 years; 47% were female and 68% presented with symptoms. A right-sided arch was present in 23%. The mean KD diameter was 47.4 mm (range, 13.0-108.0 mm). The most common indication for treatment was symptoms (59%), followed by aneurysm size (38%). The most common symptom reported was dysphagia (44%). A ruptured KD was treated in 4.2% of cases, with a mean diameter of 43.9 mm (range, 18.0-100.0 mm). An open procedure was performed in 101 cases (36%); the most common approach was ASA ligation with subclavian transposition. An endovascular or hybrid approach was performed in 184 patients (64%); the most common approach was thoracic endograft and carotid-subclavian bypass. A staged operative strategy was employed more often than single setting repair (55% vs 45%). Compared with endovascular or hybrid approach, those in the open procedure group were more likely to be younger (49 years vs 61 years; P < .0001), female (64% vs 36%; P < .0001), and symptomatic (85% vs 59%; P < .0001). Complete or partial symptomatic relief at 1 year after intervention was 82.6%. There was no association between modality of treatment and symptom relief (open 87.2% vs endovascular or hybrid approach 78.9%; P = .13). After the intervention, 11 subclavian occlusions (4.5%) occurred; 3 were successfully thrombectomized resulting in a primary and secondary patency of 95% and 96%, respectively, at a median follow-up of 39 months. Among the 33 reinterventions (12%), the majority were performed for endoleak (36%), and more reinterventions occurred in the endovascular or hybrid approach than open procedure group (15% vs 6%; P = .02). The overall survival rate was 87.3% at a median follow-up of 41 months. The 30-day stroke and death rates were 4.2% and 4.9%, respectively. Urgent or emergent presentation was independently associated with increased risk of 30-day mortality (odds ratio [OR], 19.8; 95% confidence interval [CI], 3.3-116.6), overall mortality (OR, 3.6; 95% CI, 1.2-11.2) and intraoperative complications (OR, 8.3; 95% CI, 2.8-25.1). Females had a higher risk of reintervention (OR, 2.6; 95% CI, 1.0-6.5). At an aneurysm size of 44.4 mm, receiver operator characteristic curve analysis suggested that 60% of patients would have symptoms. CONCLUSIONS: Treatment of ASA/KD can be performed safely with low rates of mortality, stroke and reintervention and high rates of symptomatic relief, regardless of the repair strategy. Symptomatic and urgent operations were associated with worse outcomes in general, and female gender was associated with a higher likelihood of reintervention. Given the worse overall outcomes when symptomatic and the inherent risk of rupture, consideration of repair at 40 mm is reasonable in most patients. ASA/KD can be repaired in asymptomatic patients with excellent outcomes and young healthy patients may be considered better candidates for open approaches versus endovascular or hybrid modalities, given the lower likelihood of reintervention and lower early mortality rate.

RESUMO

PURPOSE: This study investigated the long-term outcomes of patients treated with fenestrated and branched endovascular aneurysm repair (F-BEVAR) or open surgical repair (OSR) for complex abdominal aortic aneurysms (c-AAAs). Complex abdominal aortic aneurysms are defined as aneurysms that involve the renal or mesenteric arteries and extend up to the level of the celiac axis or diaphragmatic hiatus but do not extend into the thoracic aorta. This study compares with a propensity-score matching the outcome of these procedures from 2 high-volume aortic centers. MATERIALS AND METHODS: All patients with c-AAAs undergoing repair at 2 centers between January 2010 and June 2016 were included. The long-term imaging follow-up consisted in a yearly computed tomography angiography (CTA) in the F-BEVAR group. Yearly abdominal ultrasound examination and 5-year CTA were performed in the OSR group. The primary endpoints were long-term mortality, aneurysm-related mortality, and chronic renal decline (CRD), defined as estimated glomerular filtration rate reduction to <60 mL/min/1.73 m2 or >20%/de novo dependence on permanent dialysis in patients with normal or abnormal preoperative renal function, respectively. Secondary endpoints included aortic-related reinterventions, target vessel occlusion, proximal aorta degeneration, access-related complications, graft infection, and the composite endpoint of clinical failure during follow-up. RESULTS: After 1:1 propensity matching, 102 consecutive patients who underwent F-BEVAR and OSR, respectively, were included. The median follow-up was 67 months. There was no significant difference in long-term overall mortality (40.2% vs 36.3%; p=0.40) and aneurysm-related mortality (6.8% vs 5.8%; p=0.30), in the F-BEVAR and OSR groups, respectively. During follow-up, late renal function decline occurred in 27 (27.8%) versus 46 patients (47.4%) in the F-BEVAR and OSR groups, respectively (p<0.01). During follow-up, 23 reinterventions (23.5%) were performed in the F-BEVAR group, and 5 (5.1%) in the OSR group (p<0.01). CONCLUSIONS: No differences in overall and aneurysm-related mortality were observed. Chronic renal decline was significantly higher after OSR, while the reintervention rate was higher in the F-BEVAR group. These long-term results reflect the outcomes of a complex procedure performed by a single experienced operator in 2 high-volume centers, and followed with a strict surveillance imaging follow-up. CLINICAL IMPACT: Nowadays, F-BEVAR and OSR are considered two established techniques for the treatment of c-AAA. However, long-term comparative outcomes are not well studied, and concerns may rise in terms of durability of the repair, risk of reinterventions and late chronic renal decline. The present study showed, with a median follow-up > 5 years, no differences in overall and aneurysm-related mortality. Chronic renal decline was significantly higher after OSR, while the reintervention rate was higher in the endovascular group. To achieve the best possible long-term outcomes, both techniques should be performed in high volume aortic centres, tailored to the patient, and with an adequate surveillance imaging.

RESUMO

OBJECTIVE: The aim of this study was to investigate the early outcomes of a novel off the shelf pre-loaded inner branched thoraco-abdominal endograft (E-nside) in the treatment of aortic pathologies. METHODS: Data from a physician initiated national multicentre registry on patients treated with the E-nside endograft, were prospectively collected and analysed. Pre-operative clinical and anatomical characteristics, procedural data, and early outcomes (90 days) were recorded in a dedicated electronic data capture system. The primary endpoint was technical success. Secondary endpoints were early mortality (90 days), procedural metrics, target vessel patency, endoleak rate, and major adverse events (MAEs) at 90 days. RESULTS: In total, 116 patients from 31 Italian centres were included. Mean ± standard deviation (SD) patient age was 73 ± 8 years and 76 (65.5%) were male. Aortic pathologies included degenerative aneurysm in 98 (84.5%), post-dissection aneurysm in five (4.3%), pseudoaneurysm in six (5.2%), penetrating aortic ulcer or intramural haematoma in four (3.4%), and subacute dissection in three (2.6%). Mean ± SD aneurysm diameter was 66 ± 17 mm; aneurysm extent was Crawford I - III in 55 (50.4%), IV in 21 (19.2%), pararenal in 29 (26.7%), and juxtarenal in four (3.7%). The procedure setting was urgent in 25 (21.5%) patients. Median procedural time was 240 minutes (interquartile range [IQR] 195, 303), with a median contrast volume of 175 mL (IQR 120, 235). The endograft's technical success rate was 98.2% and the 90 day mortality rate was 5.2% (n = 6; 2.1% for elective repair and 16% for urgent repair). The 90-days cumulative MAE rate was 24.1% (n = 28). At 90 days, there were 10 (2.3%) target vessel related events (nine occlusions and one type IC endoleak) and one type 1A endoleak requiring re-intervention. CONCLUSION: In this real life, non-sponsored registry, the E-nside endograft was used for the treatment of a broad spectrum of aortic pathologies, including urgent cases and different anatomies. The results showed excellent technical implantation safety and efficacy, as well as early outcomes. Longer term follow up is needed to better define the clinical role of this novel endograft.

RESUMO

BACKGROUND: Aberrant subclavian artery (ASA) with or without Kommerell's diverticulum (KD) is a rare anatomic aortic arch anomaly that can cause dysphagia and/or life-threatening rupture. The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch. METHODS: Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions. RESULTS: 288 patients with ASA with or without KD were identified; 222 left-sided aortic arch (LAA), and 66 right-sided aortic arch (RAA). Mean age at repair was younger in LAA 54 vs. 58 years (P = 0.06). Patients in RAA were more likely to undergo repair due to symptoms (72.7% vs. 55.9%, P = 0.01), and more likely to present with dysphagia (57.6% vs. 39.1%, P < 0.01). The hybrid open/endovascular approach was the most common repair type in both groups. Rates of intraoperative complications, death within 30 days, return to the operating room, symptom relief and endoleaks were not significantly different. For patients with symptom status follow-up data, in LAA, 61.7% had complete relief, 34.0% had partial relief and 4.3% had no change. In RAA, 60.7% had complete relief, 34.4% had partial relief and 4.9% had no change. CONCLUSIONS: In patients with ASA/KD, RAA patients were less common than LAA, presented more frequently with dysphagia, had symptoms as an indication for intervention, and underwent treatment at a younger age. Open, endovascular and hybrid repair approaches appear equally effective, regardless of arch laterality.

RESUMO

OBJECTIVE: To perform a scoping review of how patients with COVID-19 are affected by acute limb ischaemia (ALI) and evaluate the recommendations of the 2020 ESVS ALI Guidelines for these patients. METHODS: Research questions were defined, and a systematic literature search was performed following the PRISMA guidelines. Abstracts and unpublished literature were not included. The definition of ALI in this review is in accordance with the ESVS guidelines. RESULTS: Most identified papers were case reports or case series, although population based data and data from randomised controlled trials were also identified. In total, 114 unique and relevant papers were retrieved. Data were conflicting concerning whether the incidence of ALI increased, or remained unchanged, during the pandemic. Case reports and series reported ALI in patients who were younger and healthier than usual, with a greater proportion affecting the upper limb. Whether or not this is coincidental remains uncertain. The proportion of men/women affected seems unchanged. Most reported cases were in hospitalised patients with severe COVID-19. Patients with ALI as their first manifestation of COVID-19 were reported. Patients with ALI have a worse outcome if they have a simultaneous COVID-19 infection. High levels of D-dimer may predict the occurrence of arterial thromboembolic events in patients with COVID-19. Heparin resistance was observed. Anticoagulation should be given to hospitalised COVID-19 patients in prophylactic dosage. Most of the treatment recommendations from the ESVS Guidelines remained relevant, but the following were modified regarding patients with COVID-19 and ALI: 1) CTA imaging before revascularisation should include the entire aorta and iliac arteries; 2) there should be a high index of suspicion, early testing for COVID-19 infection and protective measures are advised; and 3) there should be preferential use of local or locoregional anaesthesia during revascularisation. CONCLUSION: Although the epidemiology of ALI has changed during the pandemic, the recommendations of the ESVS ALI Guidelines remain valid. The above mentioned minor modifications should be considered in patients with COVID-19 and ALI.

RESUMO

OBJECTIVES: We aim to describe real-world outcomes from multicenter data about the efficacy of adjunct Heli-FX EndoAnchor usage in preventing or repairing failures during infrarenal endovascular aneurysm repair (EVAR), so-called EndoSutured-aneurysm-repair (ESAR). METHODS: The current study has been assigned an identifier (NCT04100499) at the US National Library of Medicine (https://ClinicalTrials.gov). It is an observational retrospective study of prospectively collected data from seven vascular surgery departments between June 2010 and December 2019. Patients included in the ANCHOR registry were excluded from this analysis. The decision for the use of EndoAnchors was made by the treating surgeon or multidisciplinary aortic committee according to each center's practice. Follow-up imaging was scheduled according to each center's protocol, which necessarily included either abdominal ultrasound or radiography or computed tomographic scan imaging. The main outcomes analyzed were technical success, freedom from type Ia endoleaks (IaEL), all-cause and aneurysm-related mortality, and sac variation and trends evaluated for those with at least six months imaging follow-up. RESULTS: Two hundred and seventy-five patients underwent ESAR in participating centers during the study period. After exclusions, 221 patients (184 males, 37 females, mean age 75 ± 8.3 years) were finally included for analysis. Median follow-up for the cohort was 27 (interquartile range 12-48) months. A median 6 (interquartile range 3) EndoAnchors were deployed at ESAR, 175 (79%) procedures were primary and 46 (21%) revision cases, 40 associated with type IaEL. Technical success at operation (initial), 30-day, and overall success were 89, 95.5, and 96.8%, respectively; the 30-day success was higher due to those with subsequent spontaneous proximal endoleak seal. At two years, freedom from type IaEL was 94% for the whole series; 96% and 86% for the primary and revision groups, respectively; whereas freedom from all-cause mortality, aneurysm-related mortality, and reintervention was 89%, 98%, and 87%, respectively. Sac evolution pre-ESAR was 66 ± 15.1 vs. post ESAR 61 ± 17.5 (p < 0.001) and for 180 patients with at least six-month follow-up, 92.2% of them being in a stable (51%) or regression (41%) situation. CONCLUSIONS: This real-world registry demonstrates that adjunct EndoAnchor usage at EVAR achieves high rates of freedom from type IaEL at mid-term including in a high number of patients with hostile neck anatomy, with positive trends in sac-size evolution. Further data with longer follow-up may help to establish EndoAnchor usage as a routine adjunct to EVAR, especially in hostile necks.

RESUMO

INTRODUCTION: The treatment of a chronic type B aortic dissection can be challenging and need a precise and multidisciplinary planning. MATERIALS AND RESULTS: A 62-year-old man presented to our hospital with acute aortic thrombosis on chronic thoracoabdominal dissection with bowel and kidney ischemia. He was submitted to urgent open surgical treatment with replacement of thoracoabdominal aorta and reimplantation of celiac trunk, superior mesenteric artery and right renal artery. During the intervention the visceral perfusion was provided with a modified Gott shunt; while the lower limb perfusion was provided by an existing right axillo-femoral and femoro-femoral bypass. The patient had a favorable course and did not report any complications. CONCLUSION: The ideal management strategy of complex post-dissection conditions has to be tailored on the single patient's features to provide the maximal efficacy and safety. If the endovascular treatment is not viable, open surgery represents a valid option.

RESUMO

BACKGROUND: Axillary artery aneurysms are rare conditions, and their causes are various. They can determine severe complications, so the treatment is extremely important. METHODS: We report the case of a young man affected by a saccular axillary artery aneurysm associated with intramuscular arteriovenous malformation, without symptoms except for the presence of a pulsatile mass. Duplex scan and computed tomography scan have been essential for a correct diagnosis and planning of the treatment. At first, the patient was submitted to coil embolization of an efferent vessel, and then he was treated surgically through ligation and detachment of the aneurysm and replacement of part of the axillary artery with a Dacron graft (Vascutek, Inchinnan, Renfrewshire, Scotland, UK). RESULTS: Follow-up at 1 and 6 months revealed normal patency of the axillary arterty and the prosthetic graft with complete exclusion and thrombosis of the aneurysm sac.No sensitive nor motor deficit were observed. CONCLUSIONS: Aneurysms of the axillary artery associated with intramuscular arteriovenous malformations are very rare, but have to be suspected. The treatment is challenging and can be surgical, endovascular, or hybrid, based on the patient's conditions and aneurysm's anatomical features.

RESUMO

OBJECTIVE: Although the long-term results of endovascular aortic repair (EVAR) with low-profile devices in patients with hostile iliac anatomies have been published, there are no reported results specifically for narrow aortic bifurcations (NAB). This study investigated the outcomes of EVAR with the INCRAFT device in NAB (<16 mm). METHODS: This multicenter retrospective study involved five vascular surgery centers. From November 2014 until June 2018, 127 patients were treated with the INCRAFT device. The patient population was divided into two groups based on aortic bifurcation diameter. They were designated as the (1) standard aortic bifurcation (SAB) group (>16 mm) and the (2) the NAB group (<16 mm). Primary end points were the differences between the two groups in terms of technical success, survival at 30 days, iliac limb patency, and reinterventions. RESULTS: The SAB group included 96 patients and the NAB group included 31 patients. The mean aortic bifurcation diameter was 25.5 mm in the SAB group and 13.2 mm in the NAB group. It is noteworthy that, in the NAB group, 21.8% of patients had aortic bifurcations with focal calcific lesions (less than one-third of the circumferential length of the bifurcation) and 48.3% showed extensive calcifications (two-thirds of the circumferential length of the bifurcation), for 29.9% of the patients in the NAB group the aortic bifurcation had a circumferential highly calcific lesion (complete occlusion of the circumferential length of the bifurcation). Technical success was 98.9% in the SAB group and 96.7% in the NAB group (P = .1). The need for iliac component stenting was not significantly different between the groups (SAB 2.0% vs NAB 3.2%; P = .07). The 1-year survival was 97.9% and 96.7% in the SAB and NAB groups, respectively, with no aneurysm-related mortality. The mean follow-up was 18.4 months and 15.3 months in the SAB and NAB groups, respectively. The iliac primary patency was 98.9 % in the SAB group and 96.8% in the NAB group (P = .088), and the primary assisted patency was 100% in both groups. CONCLUSIONS: EVAR with INCRAFT in NABs showed acceptable results. In this multicenter study, the results were comparable in terms of technical success and iliac patency rate between patients with SABs and NABs.

RESUMO

OBJECTIVE: The aim of this study was to evaluate early and late results of hybrid repair techniques for Kommerell's diverticulum (KD). METHODS: All patients who underwent hybrid repair (thoracic endovascular aortic repair + supra-aortic debranching) for KD between 2009 and 2018 were included in this retrospective multicenter study (three Italian centers). A proximal landing zone (PLZ) of at least 2 cm of healthy aorta was considered adequate for the deployment of a standard thoracic stent graft. The early end points were technical success, in-hospital mortality, and cerebrovascular events. Late outcomes included survival, reintervention, and patency of supra-aortic debranching. We used an embryogenetic anomaly based aortic arch classification for PLZ evaluation to identify the most appropriate hybrid adjunct. RESULTS: Sixteen patients with KD were included. According to the aforementioned classification, stent graft deployment was required in six patients (37.5%) in PLZ 0, nine patients (56.3%) in PLZ 1, and one patient (6.3%) in PLZ 2. Technical success was achieved in all patients. One patient (6.3%) died in the hospital because of posterior cerebral hemorrhage after total debranching (PLZ 0). No further cerebrovascular events were observed. One patient (6.3%) had an asymptomatic left subclavian artery-right left subclavian artery bypass occlusion and required early reintervention. The 30-day secondary patency of supra-aortic debranching was 100%. Two type II endoleaks (12.5%) were detected at 1 month through computed tomography angiography. Further transient complications were found in three cases: hemidiaphragm paralysis in one patient and recurrent laryngeal nerve paralysis in two patients. At a mean follow-up of 48 months, four patients had died because of nonaortic reasons, and one RCCA-right subclavian artery bypass had lost its patency. None of the patients reported any growth of KD after hybrid repair. Ten patients (62.5%) showed aneurysmal sac shrinkage of at least 5 mm. CONCLUSIONS: Hybrid repair is confirmed to be a safe and effective approach for KD. Operative risk is associated primarily with the invasiveness of the hybrid adjunct.

RESUMO

CASE REPORT: We report an unusual case of a 65-year-old male patient with horseshoe kidney, who underwent a successful open repair for an abdominal aortic aneurysm (AAA). The accessory renal arteries were perfused with histidine-tryptophan-ketoglutarate (HTK) solution (Custodiol®; Dr. Franz-Kohler Chemie GmbH, Bensheim, Germany) during the vascular reconstruction. There were no creatinine and estimated glomerular filtration rate (eGFR) modifications in the postoperative time. In the literature, only two cases of Custodiol solution for kidney protection during aortic surgery are reported. To the best of our knowledge, this is the first case of Custodiol perfusion for horseshoe kidney protection. DISCUSSION: The concomitant presence of horseshoe kidney and an AAA requires a specific preoperative planning. This is necessary to define the appropriate surgical procedure and strategy. The onset of acute kidney injury is an aspect that must always be taken into consideration during aortic surgery, even more in the case we are reporting. Indeed, despite the complexity of the kidney anatomy, the use of Custodiol solution allowed a proper maintenance of the perioperative renal function, as shown by the postoperative levels of creatinine and eGFR. CONCLUSIONS: Preoperative planning and organ preservation are crucial in AAA open repair, especially in the presence of congenital anomalies such as horseshoe kidney.

RESUMO

BACKGROUND: Radiation therapy may accelerate atherosclerosis with progressive stenosis and occlusions of supra-aortic trunks. METHODS AND RESULTS: We report the case of a 44-year-old woman with radiation-induced occlusion of the supra-aortic trunks presenting with recurrent cerebrovascular insufficiency after an unusual surgical revascularization technique (retrograde femoral-axillary bypass) performed for late failure of previous endovascular treatment. CONCLUSIONS: Customized surgical procedure can be considered as a bailout to improve cerebral blood inflow in selected cases.

RESUMO

We report an unusual case of a 53-year-old male patient, previously undergone an extra-anatomic right-to-left iliofemoral bypass graft, who has developed gross hematuria after 4 months. The cystoscopic examination revealed a wall injury due to the presence of the graft crossing the bladder. Iatrogenic bladder injuries during vascular surgery are extremely rare. In the literature, only 11 cases of transvesical graft are reported. The complication has been resolved with the removal of the misplaced graft and the reconstruction of the bypass with silver-coated Dacron prosthesis. Despite the rarity of this complication, postoperative ultrasound of the bladder is recommended to timely detect any injury and adopt a correct surgical strategy.

RESUMO

OBJECTIVE: The objective of this study was to investigate the outcomes of patients with visceral aortic patch (VAP) aneurysms after open repair of thoracoabdominal aortic aneurysm (TAAA) treated with three different approaches: open, hybrid, and endovascular repair. METHODS: Between 1993 and 2016, there were 29 cases treated for VAP aneurysm after initial TAAA open repair (median time interval, 6.2 years; interquartile range, 4-8 years). Three different treatment modalities were employed: redo open repair (O group) in 14 cases (48.3%), hybrid repair (H group) in 10 cases (34.5%), and endovascular custom-made fenestrated endograft repair (E group) in 5 cases (17.2%). Early (30-day) and midterm results were recorded. The primary end point was a composite major adverse event score: any 30-day death plus any grade ≥2 postoperative complications plus any surgical revision classified according to the Society for Vascular Surgery/American Association for Vascular Surgery reporting standards. Patients were evaluated with computed tomography scans in the outpatient clinic at 3, 6, and 12 months and annually thereafter. RESULTS: The composite major adverse event score significantly differed among groups (O group, 79%; H group, 60%; E group, 0%; P = .009). Two cases (6.9%) of temporary delayed spinal cord ischemia (grade 1) were observed in both the E and H groups. The treatment modality employed was differently associated with blood loss ≥1000 mL (O group, 79%; H group, 40%; E group, 0%; P = .007), number of packed red blood cells transfused ≥3 units (O group, 100%; H group, 90%; E group, 40%; P = .003), intensive care unit stay >1 day (O group, 71%; H group, 70%; E group, 0%; P = .014), and length of hospital stay ≥7 days (O group, 79%; H group, 80%, E group, 20%; P = .034). At short term (6 months), we observed one endovascular reintervention in the E group and one fatal visceral graft thrombosis in the H group. At a median follow-up of 30 months (interquartile range, 15-75 months), we observed another aneurysm-related death in the H group due to graft infection and four unrelated deaths (one case in the H group and two cases in the O group). CONCLUSIONS: This retrospective study confirms that repair of VAP aneurysms that develop after open repair of TAAAs can be performed with open, hybrid, and endovascular techniques. Current practice favors endovascular repair if possible, but a conclusion that it is superior to any other technique requires validation in a larger sample or a randomized trial.

RESUMO

BACKGROUND: Off-the-shelf devices for branched endovascular aortic repair of thoracoabdominal aortic aneurysm (TAAA) have been developed to overcome the manufacturing- and logistics-related delays characteristic of device customization. Nonetheless, the structural requirements of branched endovascular aortic repair, together with the need for additional thoracic components to suit different anatomies, might lead to a large sacrifice of healthy aorta. METHODS: We enrolled 18 consecutive TAAA patients treated between 2010 and 2016 in two centers employing the off-the-shelf t-Branch (Cook Medical, Bloomington, Ind) device (TB group). We matched these 18 patients one-to-one with another 18 patients of the 464 consecutive TAAAs treated in the same period by means of open repair (O group) in one of the two centers. The patients were matched on the basis of t-Branch feasibility, distance from the left subclavian artery to the beginning of the aneurysm, and diameter of proximal landing zone evaluated at preoperative computed tomography angiography. We compared the overall length of sacrificed healthy native aorta (the sealing zone in the TB group) in the two groups according to postoperative computed tomography angiography, and we investigated the number of intercostal arteries lost from that healthy aortic segment. We calculated also the real unnecessary sacrificed aorta by subtracting the compulsory minimum neck coverage requested to obtain the proximal sealing (25 mm). RESULTS: We matched one-to-one six extent II, seven extent III, and five extent IV TAAAs. Overall, the length of sacrificed healthy aorta was longer (P < .001) in the TB group (median length: TB group, 49 mm [interquartile range (IQR), 31-60 mm]; O group, 14 mm [IQR, 10-20 mm]), and consequently the number of intercostal arteries lost (median number of pairs lost: TB group, four [IQR, three-four]; O group, two [IQR, one-three]) was higher (P = .004). Stratifying the results according to TAAA extent and after having subtracted from the TB group the length of aorta required for proximal sealing (25 mm), the length of sacrificed healthy aorta was longer (P = .008) only in the extent IV TAAA, 125 mm (IQR, 56-155 mm). The number of intercostal artery pairs sacrificed was longer only in extent III TAAA (P = .043) and extent IV TAAA (P = .024). No significant 30-day clinical outcomes difference was observed between the matched groups. CONCLUSIONS: The use of the t-Branch device compared with open repair is associated with a greater sacrifice of healthy aorta in extent IV TAAA and with an increased loss of intercostal arteries arising from healthy aortic proximal neck. The theoretical possible increased risk of spinal cord ischemia secondary to the routine use of this off-the-shelf device should thus be analyzed further.
