RESUMO
BACKGROUND: Persistent type II endoleak has necessitated prolonged surveillance and is a reason for reintervention after infrarenal endovascular aneurysm repair (EVAR). The aim of this study was to assess the association of thrombus burden (TB) within the aneurysmal sac in the prediction of a persistent type II endoleaks. METHODS: Consecutive patients who underwent infrarenal EVAR from October 2009 to October 2017 in a single vascular network were included. TB was assessed on preoperative computed tomography angiogram and was defined as a percentage of thrombus across the maximal sac diameter in comparison with the luminal diameter measured orthogonally at the same level. Patients were categorized into three groups: low TB (<25%), medium TB (25%-50%), and high TB (>50%). All patients underwent postoperative EVAR surveillance comprising computed tomographic angiography or duplex ultrasound imaging. Type II endoleak observed for more than 1 year was defined as persistent type II endoleak. Odds ratio (OR) and Student's t-test were used to determine significance. RESULTS: Some 275 EVARs were performed in the study period. A total of 45 procedures were excluded because of either iliac-only intervention (n = 9), no preoperative information (n = 7), abandoned (n = 1), or less than 1 year's follow-up data (n = 28). For the 230 procedures included, the median follow-up was 43 (12-102) months. There were no significant differences between the groups for age, gender, and comorbidities nor preoperative sac diameter. There was high interobserver reliability with a kappa value of 0.89 (0.84-0.94) with a total discordance of 7% across the cohorts. Persistent type II endoleak occurred significantly more frequently with reduced TB: 41% of the low TB cohort compared with 4% of the high TB cohort (OR, 15.36 [3.5-67.3]; P = .0003). Reintervention was also significantly more likely to occur in the presence of a persistent type II endoleak compared with its absence; n = 12 of 13 (92%) patients who underwent reintervention had a persistent type II endoleak (OR, 43.4 [5.5-242]; P = .0003). Sac size reduction was significantly greater in medium TB and high TB cohorts when compared with low TB: -25% and -27% vs -15% (P = .0046 and P < .0001). Decreased TB was associated with a significant increase in inferior mesenteric artery (IMA) patency, the mean TB, where the IMA was patent, being 29% compared with 40% where the IMA was occluded P < .0001. When considered together, patients with a low TB and a patent IMA were even more likely to have a persistent type II endoleak when compared with those with a high TB and an occluded IMA (OR, 34.1 [1.99-583]; P = .015). CONCLUSIONS: Low TB is associated with increased rates of persistent type II endoleak, especially in the presence of a patent IMA. High TB is associated with increased sac regression and low reintervention rates. TB can be assessed reliably and could be used for risk stratification in the planning of infrarenal EVAR. Pre-emptive embolization of IMA or lumbar vessels in those with low TB may be beneficial. TB could be a useful tool for designing a post-EVAR surveillance regimen.

OBJECTIVE: Long term surveillance after endovascular aneurysm repair (EVAR) is essential to detect late complications, but there is variation in practice. The European Society for Vascular Surgery (ESVS) made a recommendation for a new surveillance protocol; one element involves risk stratifying patients depending on sac size reduction and presence of endoleak at their 30 day computed tomography angiogram into low risk groups (delayed imaging to five years) or higher risk groups (continue with the current protocol). The aim was to test this suggested protocol retrospectively within an EVAR patient cohort. METHODS: Data on EVARs performed from October 2009 to October 2019 were collected. Information gathered from an existing surveillance programme was used to assess the proposed ESVS protocol. All patients who underwent re-intervention were reviewed to see whether adopting the proposed ESVS protocol would have detected these events. RESULTS: In total, 309 procedures were included. Altogether, 219 of these patients had no endoleak (70.9%) and 86 had a type II (27.8%) endoleak. Only four developed a type I or III endoleak. No patient in the low risk cohort (no initial endoleak or sac shrinkage > 1 cm) required secondary intervention. Five year follow up data were available for 103 patients. In the type II endoleak group, there were 28 secondary interventions in 22 patients. No patient experienced a ruptured aneurysm within five years post-operatively. Had the proposed ESVS protocol been followed, all patients requiring a secondary intervention or with increasing sac size would have been detected/captured. Further, adherence to the ESVS guidelines would have resulted in 103 patients with a five year follow up history qualifying for reduced surveillance. A further 120 patients who had reached the three and four year follow up timepoints could have qualified for a reduced surveillance, reducing imaging cost further. CONCLUSION: Adopting the proposed ESVS EVAR surveillance protocol safely identified "low risk" patients who did not go on to require a secondary intervention. These patients could benefit from reduced surveillance scanning.

PURPOSE: To report the risk of all-cause mortality after treatment with paclitaxel-coated devices vs uncoated controls in patients with chronic limb-threatening ischemia (CLTI). MATERIALS AND METHODS: A search of the PubMed, Embase, Cochrane, CINAHL, DARE, and PROSPERO databases was made on 5 November 2019 to identify randomized controlled trials (RCT) using intention-to-treat analysis to compare a paclitaxel-coated device to an uncoated device in PAD patients having clinical follow-up of at least 6 months. Half of the study population had to have CLTI or extractable data on the CLTI subgroup if <50%. The search identified 11 trials having 1450 patients randomized to a paclitaxel-coated device (n=866) or an uncoated control (n=584). There were 1367 (94.3%) patients with CLTI (range 10-429). The single endpoint was all-cause mortality, which was analyzed by pooling the mortality data in a DerSimonian and Laird random effects model. Summary statistics are expressed as relative risk ratios (RR) with a 95% confidence interval (CI). RESULTS: The mean follow-up was 25.6 months (range 6-60); 10 of 11 studies reported a minimum 12-month follow-up. There were 161 (18.6%) deaths among 866 subjects in the paclitaxel device group and 116 deaths among 584 (19.9%) subjects in the non-coated control group (RR 0.93, 95% CI 0.78 to 1.12, p=0.45). CONCLUSION: There was no observed difference in short- to midterm mortality among a pooled patient population of predominately CLTI patients treated with paclitaxel-coated balloons or stents compared with uncoated controls.

OBJECTIVE: Hospital and surgeon operative caseload is thought to be associated with peri-operative mortality following the non-elective repair of aortic aneurysms; however, whether such an association exists within the Australian healthcare setting is unknown. METHODS: The Australasian Vascular Audit was interrogated to identify patients undergoing non-elective (emergency [EMG] or semi-urgent [URG]) aortic aneurysm repair between 2010 and 2016, as well as their treating surgeon and hospital. Hierarchal logistic regression modelling was used to assess the impact of caseload on outcomes after both endovascular (EVAR) and open surgical repair (OSR). RESULTS: Volume counts were determined from 14 262 patients (4 121 OSR and 10 141 EVAR). After exclusion of elective procedures and duplicates, 1 153 EVAR (570 EMG and 583 URG) and 1 245 OSR (946 EMG and 299 URG) non-elective cases remained for the analysis. Crude mortality was 24.0% following OSR (EMG 29.2%; URG 7.7%) and 7.5% following EVAR (EMG 12.6%; URG 2.4%). Univariable analysis demonstrated an association between OSR mortality and hospital volume (quintile [Q] 1: 25.3%, Q2: 27.8%, Q3: 23.9%, Q4: 27.0%, Q5: 16.2%; p = .030), but not surgeon (Q1: 25.2%, Q2: 27.4%, Q3: 26.0%, Q4: 21.4%, Q5: 19.5%, p = .32). Multivariable analysis confirmed this association (odds ratio (OR) [95% CI]; Q1 vs 5: 1.91 [1.13-3.21], Q2 vs. 5: 2.01[1.24-3.25], Q3 vs. 5: 1.41 [0.86-2.29], Q4 vs. 5: 1.92 [1.17-3.15]; p = .020). The difference was most pronounced in the EMG OSR group [Q1 - 3 vs. 4-5] (OR 1.63 [1.07-2.48]; p = .020). Mortality after EVAR was not associated with either hospital (Q1: 6.3%, Q2: 10%, Q3: 6.8%, Q4: 4.5%, Q5: 10%; p = .14) or surgeon volume (Q1: 9.3%, Q2: 5.7%, Q3: 8.1%, Q4: 7.0%, Q5: 7.3%; p = .67). CONCLUSION: There is an inverse correlation between hospital volume and peri-operative mortality following EMG open repair of aortic aneurysm. These data support restructuring Australian pathways of care to direct suspected ruptured aneurysm to institutions that reach a minimum volume threshold.

Purpose: To report the risk of all-cause mortality in patients who underwent dialysis access treatment using paclitaxel-coated devices compared with percutaneous transluminal angioplasty (PTA) with an uncoated balloon. Materials and Methods: A systematic review and meta-analysis of randomized controlled trials were performed to investigate the mortality outcomes associated with paclitaxel-coated devices in the treatment of patients with a failing dialysis access (last search date February 28, 2019). The primary endpoint was all-cause mortality. This analysis included 8 studies comparing paclitaxel-coated balloon (PCB) angioplasty (n=327) and PTA (n=331) in the treatment of failing dialysis access. None investigated paclitaxel-coated stents. Mortality data were pooled using a random effects model. Statistical heterogeneity was evaluated with a chi-square test and the I2 statistic. Summary statistics are expressed as relative risk ratios (RR) with a 95% confidence interval (CI). Results: At the pooled mean follow-up of 13.5 months (median 12, range 6-24) all-cause mortality was similar in the PCB group (13.8%) compared with PTA (11.2%; RR 1.26, 95% CI 0.85 to 1.89, p=0.25; I2=0%). Subgroup analysis, stratified according to length of follow-up, confirmed that there were no statistically significant differences in mortality at short- and midterm follow-up [6-month (8 studies): 5.2% vs 4.8%, RR 1.24, 95% CI 0.62 to 2.47, p=0.55; 12-month (6 studies): 6.3% vs 6.0%, RR 1.06, 95% CI 0.43 to 2.63, p=0.90; and 24-month (3 studies): 19.0% vs 13.5%, RR 1.38, 95% CI 0.90 to 2.12, p=0.14). Conclusion: The analysis found no difference in short- to midterm mortality among patients treated with a drug-coated balloon compared with PTA. With proven benefit and no evidence of harm, the authors recommend ongoing use of PCB for the failing dialysis access.

OBJECTIVES: Operative caseload is thought to be associated with peri-operative mortality following intact aortic aneurysm repair. The aim was to study that association in the Australian setting, which has a unique healthcare provision system and geographical population distribution. METHODS: The Australasian Vascular Audit database was used to capture volume measurements for both individual surgeon and hospital and to separate it into quintiles (1, lowest, to 5, highest) for endovascular (EVAR), open surgical repair (OSR), and subgroups of repair types between 2010 and 2016. Multivariable logistic regression modelling was used to assess the impact of caseload volumes on in hospital mortality after adjustment for confounders. RESULTS: Volume counts were determined from 14,262 aneurysm repair procedures (4121 OSR, 10,106 EVAR). After exclusions, 2181 OSR (161 complex, 2020 standard) and 7547 EVAR (6198 standard, 1135 complex, 214 thoracic (TEVAR)) elective cases were available for volume analysis. Unadjusted mortality after EVAR was unaffected by either surgeon (Quintile 1, 1.0%; Quintile 5, 0.9%; p = .28) or hospital volume (Quintile 1, 0.8%; Quintile 5, 1.3%; p = .47). However, univariable analysis of the TEVAR subgroup revealed a significant correlation with hospital volume (Quintiles 1-2 vs. Quintiles 3-5; p = .02). Univariable analysis for OSR demonstrated a marginal, non-significant value for surgeon (Quintile 1, 4.0%; Quintile 5, 3.6%; p = .06), but not hospital volume (Quintile 1, 4.7%; Quintile 5, 4.0%; p = .67). After adjustment for confounders hospital volume remained a significant predictor of peri-operative TEVAR mortality (Quintile 1-2 vs. 3-5; OR 5.62, 95% CI 1.27-24.83; p = .02) and surgeon volume a predictor following standard OSR (Quintile 1-2 vs. Quintile 3-5; OR 2.15, 95% CI 1.21-3.83; p = .01). CONCLUSIONS: There is an inverse correlation between both surgeon volume of open aortic aneurysm repair, hospital volume of thoracic endovascular aneurysm repair and in hospital mortality. These findings suggest that in Australia TEVAR should be performed by high volume hospitals and OSR by high volume surgeons.

PURPOSE: To compare the total initial treatment costs for open surgery, endovascular revascularization, and primary major amputation within a single-payer healthcare system. METHODS: A multicenter, retrospective analysis was undertaken to evaluate 1138 patients with symptomatic peripheral artery disease (PAD) who underwent 1017 endovascular procedures, 86 open surgeries, and 35 major amputations between 2013 and 2016. A cost-mix analysis was performed on individual patient data generated for selected diagnosis-related groups. Mean costs are presented with the 95% confidence interval (CI). RESULTS: There was no intergroup difference in demographics or private health insurance status. However, the amputation group had a higher proportion of emergency procedures (68.6% vs 13.3% vs 27.9%, p<0.001) and critical limb ischemia (88.6% vs 35.9% vs 37.2%, p<0.001) compared with the endovascular therapy and open surgery groups, respectively. The endovascular revascularization group spent less time in hospital and used fewer intensive care unit (ICU) resources compared with the open surgery and major amputation groups (hospital length of stay: 3.4 vs 10.0 vs 20.2 days, p<0.01; ICU: 2.4 vs 22.6 vs 54.6 hours, p<0.01), respectively. While mean prosthetic and device costs were higher in the endovascular group [AUD$2770 vs AUD$1658 (open) and AUD$1219 (amputation), p<0.01], substantial disparities were observed in costs associated with longer operating theater times, length of stay, and ICU utilization, which resulted in significantly higher costs in the open and amputation groups. After adjusting for confounders, the AUD$18,396 (95% CI AUD$16,436 to AUD$20,356) mean cost per admission for the endovascular revascularization group was significantly less (p<0.001) than the open surgery (AUD$31,908, 95% CI AUD$28,285 to AUD$35,530) and major amputation groups (AUD$43,033, 95% CI AUD$37,706 to AUD$48,361). CONCLUSION: Endovascular revascularization procedures for PAD cost the health payer less compared with open surgery and primary amputation. While devices used to deliver contemporary endovascular therapy are more expensive, the reduction in bed days, ICU utilization, and related hospital resources results in a significantly lower mean total cost per admission for the initial treatment.

BACKGROUND: Recurrent herpes labialis (RHL) is one of the most common viral infections worldwide. The available treatments have limited efficacy in preventing the recurrence of ulcerative lesions and reducing the duration of illness. The objective of this review was to identify the effectiveness of topical corticosteroids in addition to antiviral therapy in the treatment of RHL infection. METHODS: A systematic review of randomized clinical trials comparing the efficacy of combined therapy (topical corticosteroids with antiviral) with placebo or antiviral alone in the management of RHL was conducted. MEDLINE, EMBASE, CINAHL, Web of Science, the Cochrane library, and Google Scholar databases were searched. We used RevMan software to conduct the meta-analysis. A fixed-effects model was used for mild to moderate heterogeneity, whereas a random-effects model was used for significant heterogeneity. Heterogeneity among trials was established using I(2) and chi-square test for heterogeneity. RESULTS: Four studies that fulfilled the selection criteria were included in this review. The total number of participants across included studies was 1,891 (range, 29 to 1,443). The antiviral drugs used were acyclovir, famciclovir, and valacyclovir. Corticosteroids used were 1% hydrocortisone and 0.05% fluocinonide. Pooled results showed that patients receiving combined therapy had a significantly lower recurrence rate of ulcerative lesions compared to those in both the placebo group (OR, 0.50; 95% CI, 0.39-0.66; P < .001) and the antiviral treatment alone group (OR, 0.73, 95% CI, 0.58-0.92; P = .007). The healing time was also significantly shorter in combined therapy in comparison to placebo (P < .001). However, there were no significant differences in healing time between combined therapy and antiviral alone. The adverse reactions in combined therapy were not significantly different than the placebo group (OR, 1.09; 95% C, 0.75-1.59; P = .85). CONCLUSION: Treatment with combined therapy is safe and more effective than placebo or antiviral alone for preventing the recurrence of ulcerative lesions in RHL infection.

Objective: A hybrid approach is being employed increasingly in the management of peripheral arterial disease. This study aimed to assess the surgical site infection (SSI) incidence of hybrid revascularisation (HR) compared with common femoral endarterectomy (CFEA) alone. Methods: This was a retrospective review of consecutive patients who underwent CFEA or HR alongside CFEA between 2017 and 2021 including one year of follow up. The primary outcome was SSI incidence. Secondary outcomes included length of surgery, duration of admission, further revascularisation surgery, limb salvage, and death. Differences in outcomes were assessed with the Student's unpaired t test, chi square test, and Fisher's exact test. Results: A total of 157 groin incisions from 155 patients were included: 78 had CFEA procedures and 79 had HR procedures. No statistical difference was found between groups for age, sex, and indication for surgery. Surgical site infection occurred in five of the CFEA patients (6%) compared with seven of the HR patients (9%) (p = 0.77). The HR procedures took significantly longer, with an average of 299 minutes compared with 220 minutes for CFEA (p < 0.001). No statistically significant difference was identified for length of admission: median stay five days for CFEA vs. four days for HR (p = 0.44). Major amputation was performed within one year in five of the CFEA procedures (6%) and five of the HR procedures (6%) (p = 1.0). Further revascularisation surgery was attempted in two patients in the HR group and six patients in the CFEA group (p =. 17). No statistically significant difference was found in the one year mortality rate: eight CFEA (10%) and seven HR (9%) (p = 0.77). Conclusion: Patients who underwent HR alongside CFEA did not have a statistically significantly increased incidence of SSI, despite increased surgical time. Using HR techniques enabled patients to have multilevel disease treated in one stage without an increased incidence of SSI.
RESUMO
COVID-19 has to date affected over 5 million people worldwide and caused in excess of 300000 deaths. One of the principal finding is that of a thrombotic tendency within the lungs leading to high mortality. There have been increasing number of reports of peripheral arterial thrombosis as well. Most cases of arterial thrombosis is noted in patient in intensive care setting. Here-in we report a case of acute bilateral lower limb arterial thrombosis in a patient recovering at home with mild COVID-19 symptoms, highlighting that patients with milder symptoms may also suffer from prothrombotic state resulting in acute arterial occlusions. Arterial thrombosis should be suspected in these patients despite the absence of predisposing factors.

INTRODUCTION: Posterior cerebral circulation strokes are most commonly caused by posterior vasculature in situ thrombosis, cardiac emboli, or arterial dissection. However, the foetal origin of the posterior communicating artery is an anatomical variant of the cerebral circulation that results in communication between the internal carotid and posterior cerebral circulation. Therefore, rarely this can result in posterior cerebral territory infarction from internal carotid artery thrombo-embolism. This is the report of a case in which a patient suffered posterior circulation stroke secondary to this anatomical variation of the circle of Willis. REPORT: A 71 year old male patient was admitted to the stroke team with seizures, headache, and confusion. Examination revealed a left sided homonymous hemianopia. Diffusion weighted magnetic resonance imaging (MRI) of the brain 36 hours into his admission revealed an acute right posterior circulation infarct with extensive haemorrhagic transformation. Duplex ultrasound three days later revealed a heavily calcified right internal carotid artery mixed echogenicity plaque with 80%-90% stenosis. Subsequent computed tomography angiography showed a large right foetal variant posterior communicating artery. Following improvement in functional status, the patient underwent uneventful carotid endarterectomy to reduce risk of future stroke. DISCUSSION: In patients presenting with posterior circulation infarction, clinicians should consider embolism from an atheromatous internal carotid artery via the variant foetal origin of posterior communicating artery. If detected, consideration should be given to undertaking carotid endarterectomy to reduce future stroke risk if no other source is detected.
RESUMO
AIM: The aim of the study is to determine whether presentation and outcomes of inflammatory abdominal aortic aneurysms (IAAA) have changed over the last five decades. METHODS: Comparison of current outcomes (January 2001 to December 2007) with results of the earliest report from our unit in 1972. RESULTS: In contemporary series, 421 patients underwent AAA repair; 38 (9%) were IAAA. In 58% patients, IAAA was an incidental finding, whereas 42% patients were symptomatic with abdominal or back pain. Of those, 32% were ruptured IAAA. Male-to-female ratio was 12:1. Thirty-day mortality was 13%; elective 11.5%; emergency 17%. Comparison with 1972 study showed no change in the incidence and gender predilection. Presentation as an incidental finding and rupture increased 4- and 2-folds, respectively. CONCLUSION: The incidence and gender predilection of IAAA have remained unchanged. The 4-fold increase in the presentation as an incidental finding reflects current trends in patient evaluation.

Tumours of the spermatic cord are rare. Most tumours of the spermatic cord are metastatic and are typically an incidental finding at orchidectomy for other pathology. Primary pathology is usually from the gastrointestinal tract. We report a very rare presentation of an asymptomatic gastrointestinal tumour as a spermatic cord mass. A male patient presented with a painless scrotal swelling. Radical orchidectomy revealed an adenocarcinoma in the spermatic cord. Further investigations disclosed an adenocarcinoma of the descending colon, metastasing to the spermatic cord that gave a false notion of a scrotal swelling secondary to infection. This unusual situation reminds us that spermatic cord metastases are rare. In the event of nonresponding scrotal swelling to antibiotics, further investigations would be prudent, whilst awaiting the definitive pathology report from the radical orchidectomy.

Cystic adventitial disease (CAD) is a rare vascular disorder, predominantly seen in young healthy men with minimal cardiovascular risk factors. Cystic adventitial disease can affect both arteries and veins. Patients with arterial CAD present with sudden onset or rapidly progressing claudication symptoms, and those with venous CAD present with limb swelling or very rarely deep vein thrombosis. Diagnosis is confirmed with the aid of imaging techniques such as ultrasonography, computed tomography, or magnetic resonance scan. Surgical resection or evacuation of the lesion is usually the preferred approach, with only mixed results reported for percutaneous endovascular techniques.

Endoleak is the classical cause of rupture of aneurysms previously treated by endovascular means. We report a rare case of a retroperitoneal liposarcoma (LIS) invading an abdominal aortic aneurysm (AAA), previously treated by endovascular repair (EVAR), causing rupture. Furthermore, a brief discussion of the diagnostic challenges posed by retroperitoneal tumors is presented with a closing note on their management.

Iliac bifurcated devices (IBDs) are used in the endovascular treatment of aorto-iliac and common iliac artery aneurysms to preserve the flow to at least one internal iliac artery thereby decreasing the risk of pelvic ischemic complications. We report the use of IBDs in preserving both the internal iliac arteries.

Communication with patients is vital in their management, and the NHS plan to copy clinic letters to patients was published in 2004. This study aims to determine whether patients are satisfied with their current communication or prefer alternative modes, overall and between different specialty clinics. A questionnaire was given to outpatients attending clinics in November to December 2006. A total of 483 patients returned the questionnaire, giving a 95 per cent response rate. Overall, 85 per cent of patients were satisfied with the current method of communication, and a significant number did want a copy of GP letters. Trend analysis suggests that, as the number of clinic visits increased, requests for copies of letters decreased (p = 0.02). Paediatric and psychiatric patients were more likely to want letters than medical and surgical patients (p = 0.003). Thus communication needs may differ between departments. Opt-in letter copy systems seem preferable.
