RESUMO
The present study aimed to investigate the associations between nature-based intervention and peripheral pulse characteristics of patients with PAOD using new smart technology specifically designed for this purpose. A longitudinal panel study performed between 1 January 2022 and 31 December 2022 included 32 patients diagnosed with peripheral arterial occlusive disease (PAOD) who were treated in the vascular surgeons' hospital "Dobb" in Valjevo. These patients were exposed for six months to moderate-intensity physical activity (MPA) in a nature-based environment. They practiced 150 to 300 min of walking 6 km/h and cycling activities (16-20 km/h) weekly as recommended for patients with chronic conditions and those living with disability. Univariate logistic regression analysis was used to identify factors associated with major improvements in peripheral pulse characteristics of patients with PAOD. After six months of MPA, half of the patients (50%, 16/32) achieved minor, and half of them major improvements in peripheral pulse characteristics. The major improvements were associated with current smoking (OR = 9.53; 95%CI = 1.85-49.20), diabetes (OR = 4.84; 95%CI = 1.09-21.58) and cardiac failure, and concurrent pulmonary disease and diabetes (OR = 2.03; 95%CI = 1.01-4.11). Our pilot study showed that patients with PAOD along with other chronic conditions and risk factors benefited more from continuous physical activity in a nature-based environment.

BACKGROUND: Covered endovascular reconstruction of aortic bifurcation (CERAB) is increasingly used as a first line-treatment in patients with aortoiliac occlusive disease (AIOD). We sought to compare the outcomes of patients who underwent CERAB compared with the gold standard of aortobifemoral bypass (ABF). METHODS: The Vascular Quality Initiative was queried for patients who underwent ABF or CERAB from 2009 to 2021. Propensity scores were generated using demographics, comorbidities, Rutherford class, and urgency. The two groups were matched using 5-to-1 nearest-neighbor match. Our primary outcomes were 1-year estimates of primary patency, major adverse limb events (MALEs), MALE-free survival, reintervention-free survival, and amputation-free survival. Standard statistical methods were used. RESULTS: A total of 3944 ABF and 281 CERAB cases were identified. Of all patients with AIOD, the proportion of CERAB increased from 0% to 17.9% between 2009 and 2021. Compared with ABF, patients who underwent CERAB were more likely to be older (64.7 vs 60.2; P < .001) and more often had diabetes (40.9% vs 24.1%; P < .001) and end-stage renal disease (1.1% vs 0.3%; P = .03). In the matched analysis (229 CERAB vs 929 ABF), ABF patients had improved MALE-free survival (93.2% [±0.9%] vs 83.2% [±3%]; P < .001) and lower rates of MALE (5.2% [±0.9%] vs 14.1% [±3%]; P < .001), with comparable primary patency rates (98.3% [±0.3%] vs 96.6% [±1%]; P = .6) and amputation-free survival (99.3% [±0.3%] vs 99.4% [±0.6%]; P = .9). Patients in the CERAB group had significantly lower reintervention-free survival (62.5% [±6%] vs 92.9% [±0.9%]; P < .001). Matched analysis also revealed shorter length of stay (1 vs 7 days; P < .001), as well as lower pulmonary (1.2% vs 6.6%; P = .01), renal (1.8% vs 10%; P < .001), and cardiac (1.8% vs 12.8%; P < .001) complications among CERAB patients. CONCLUSIONS: CERAB had lower perioperative morbidity compared with ABF with a similar primary patency 1-year estimates. However, patients who underwent CERAB experienced more major adverse limb events and reinterventions. Although CERAB is an effective treatment for patients with AIOD, further studies are needed to determine the long-term outcomes of CERAB compared with the established durability of ABF and further define the role of CEARB in the treatment of AIOD.

PURPOSE: To report a case of paracentral acute middle maculopathy (PAMM) due to branch retinal artery occlusion (BRAO) as a complication of COVID-19. METHODS: A case report evaluated through spectral-domain optical coherence tomography (SD-OCT), fluorescein angiography, and OCT angiography. RESULTS: A 55-year-old man complained of blurred vision in the right eye. He presented with anosmia and tested positive for COVID-19 one week before. Fundus examination revealed a superior temporal whitening of the retina, SD-OCT showed a hyperreflective band-like lesion on the nuclear layer consistent with PAMM. CONCLUSION: COVID-19 infection involves inflammatory and thrombotic events. Even patients with just anosmia may have complications such as BRAO associated with PAMM.
RESUMO
OBJECTIVE: This study aimed to evaluate the correlation between the Society for Vascular Surgery (SVS) Wound, Ischemia and foot infection (WIfI) classification system and clinical outcomes for 1-year limb amputation-free survival (AFS), freedom from reintervention, and wound healing rate in a cohort of patients affected by chronic limb-threatening ischemia treated exclusively by endovascular procedures. METHODS: We analyzed a prospective, consecutive cohort of 203 patients (203 limbs) who underwent infrainguinal endovascular revascularization at a single center between March 2018 and January 2021. These patients were stratified into clinical stages 1 to 4 based on the SVS WIfI classification and categorized into two groups: WIfI 1 to 3 (n = 101 limbs) and WIfI 4 (n = 102 limbs). The SVS objective performance goals of 1-year limb AFS, freedom from reintervention, and wound healing were compared between the groups and assessed using the Kaplan-Meier method. Angiographic lesion characteristics and angioplasty details were compared. RESULTS: The average age was 72.4 years (44.3% male, 85.2% had hypertension, 80.3% had diabetes, and 87.7% had tissue loss). There were statistical differences between the groups in 1-year limb AFS Kaplan-Meier rate between WIfI clinical stages 1 to 3 group and WIfI clinical stage 4 group (82% vs 66%, respectively; P < .001), but there was no statistical difference in freedom from reintervention and wound healing rates between the groups (70% vs 64% [P = .62] and 74% vs 79% [P = .90], respectively). Owing to angiographic lesion characteristics, femoropopliteal and infrapopliteal segment distributions were similar between the groups, but there was a statistical difference in target lesion location to tibial vessels (55.4% vs 71.6%, respectively; P = .025). CONCLUSIONS: In this cohort of patients with chronic limb-threatening ischemia, SVS WIfI clinical stage 4 had worse results in the 1-year limb AFS rate, but there was no statistical difference in freedom from reintervention and wound healing rates between the groups.
RESUMO
A 58-year-old woman developed new-onset recurrent ascites after the recent initiation of cemiplimab for the treatment of advanced basal cell carcinoma. A comprehensive serological workup for viral, metabolic, and autoimmune causes was unrevealing. Transjugular liver biopsy demonstrated parenchymal changes consistent with a diagnosis of sinusoidal obstruction syndrome. While this is a condition commonly observed in patients after hematopoietic stem cell transplantation or use of chemotherapeutic agents, it should also be considered in patients who develop new-onset liver dysfunction after the initiation of checkpoint inhibitors.
RESUMO
A rare cause of limb ischemia in young patients, adductor canal syndrome, can be debilitating and result in functional impairment. Diagnosis and treatment may be delayed due to this vascular disease's rarity in young people and because the presenting symptoms can overlap with other more common causes of leg pain in young athletes. Here, authors discuss a young athletic patient with a history of year-long claudication. The patient's reported symptoms, exam findings, and imaging results were consistent with a diagnosis of adductor canal syndrome. This case proved uniquely challenging, given the extent of disease and illustrates potential approach considerations.
RESUMO
PURPOSE: To evaluate the occurrence of transient central retinal artery occlusion following intravitreal anti-vascular endothelial growth factor injection. METHODS: Prospective, observational study of 807 patients (807 eyes) who were given intravitreal injections of ranibizumab or aflibercept to treat any cause of retinal vascular diseases between 1 January 2017 and 30 November 2018 at the Federal Fluminense University Hospital in Niteroi, and a private facility in Rio de Janeiro, Brazil. Patients who did not present transient central retinal artery occlusion were excluded. RESULTS: Among 4069 injections, only 18 patients (0.44%) presented transient central retinal artery occlusion, 14 mild cases (77.7%), and 4 severe cases (22.3%). The clinical factors associated with more severe cases of transient central retinal artery occlusion were the duration of the transient central retinal artery occlusion (p = 0.001), number of prior injections (p = 0.01), and a positive carotid Doppler test (p = 0.01). Twelve cases (66.6%) had positive carotid artery obstruction (atheroma plaque size ≥70%) while 6 cases (33.3%) had negative carotid artery obstruction (atheroma plaque size <70%). The age group >60 years old (p = 0.06), cup/disc ratio >0.6 (p = 0.06), and pseudophakic lens status were also factors with association with transient central retinal artery occlusion, although did not meet criteria for statistical significance. The only patient who experienced a recurrent episode of transient central retinal artery occlusion had diabetic macular edema, positive carotid Doppler test, and cup/optic disc ratio >0.6. CONCLUSION: Transient central retinal artery occlusion is a rare adverse event that can appear in patients with retinal vascular disease receiving anti-vascular endothelial growth factor therapy. The atheroma plaque size and the number of prior injections can be associated with the severity of the event.

INTRODUCTION: Surgical approach of aortoiliac occlusive disease (AOD) with aorto-bi-femoral graft or endarterectomy, has been the first line treatment with patency rates up to 90%. Nevertheless, this procedure has an early mortality rate of 4%. Vascular complications of aorto-bi-femoral graft have an average incidence of 5-10% and development of incisional hernia in 10% of the cases. The Covered Endovascular Reconstruction of Aortic Bifurcation or CERAB technique, as a new approach is shaping up to be a promising approach. However, there are few studies in Latin America and the Caribbean. MATERIALS AND METHODS: Retrospective multicenter study. All patients treated with the CERAB technique between February 2015 and June 2021 in three hospitals. RESULTS: A total of 9 patients (5 male and 4 female) were treated with the CERAB technique. Only one patient died. Of the total number of patients, 41.2% had a TASC II - C classification, and 58.8% had a TASC II - D classification. Complications included dissection in only 2 patients, massive bleeding in 1 patient and hematoma in 3 patients. The average number of days in critical care was 1.2 days and 2.6 in hospitalization. Two patients required endovascular reintervention. Primary patency was present in 66.7% of the patients. DISCUSSION: The CERAB technique presents a low morbidity and mortality with an 88.9% of technical success rate. None of our patients needed Chimney CERAB procedure. Our results are similar to those reported in the literature, where they report primary patency rates between 82% and 97%.
