RESUMO

An abdominal aortic aneurysm (AAA) in children is a rare clinical condition, with idiopathic AAAs even more atypical. We report a case of a 19-month-old girl with incidental findings of an infrarenal AAA and right common iliac artery aneurysm during workup for heart failure. Extensive genetic testing was unremarkable for connective tissue disorders. An aortic bi-iliac artery bypass with a Dacron graft from the infrarenal aorta to the right external iliac artery and left common iliac artery was performed. The patient achieved complete recovery and only required one oral hypertensive medication at 30 days of follow-up. Wide patency of the graft was observed on the 3-month follow-up computed tomography angiogram.

RESUMO

In recent years, deep venous stenting has increasingly become a treatment strategy for post-thrombotic syndrome. Stent thrombosis can occur, resulting in symptom recurrence despite medical therapy, and there are few options available for durable stent patency restoration. We present a case of a 50-year-old male with prior iliocaval reconstruction that experienced recurrent left lower extremity swelling secondary to occlusion of left external iliac and common iliac vein stents during follow-up. Mechanical thrombectomy with the RevCore System and angioplasty was performed. One month later, the patient demonstrated widely patent bilateral iliac vein stents and complete symptomatic resolution. The RevCore System is a feasible alternative for treatment of chronic in-stent thrombosis.

RESUMO

Inferior vena cava (IVC) atresia is a rare congenital anomaly. Standardized treatment is not well defined due to its uncommon presentation, with this pathology associated with an increased risk of unprovoked lower extremity deep vein thrombosis (DVT). We present a case of a 32-year-old man who was admitted for bilateral lower extremity edema and pain and was found to have bilateral extensive iliofemoral and femoropopliteal DVT, absence of IVC filling, and extensive tortuous collateralization arising from the pelvic veins to the azygos vein. Bilateral mechanical thrombectomy and endovascular iliocaval reconstruction was performed. Three months later, the patient demonstrated widely patent iliocaval stents and the absence of DVT. Endovascular treatment of IVC atresia is feasible and optimizes the reduction of thrombus burden.

RESUMO

OBJECTIVE: Superficial femoral artery (SFA) stenting is a common treatment for peripheral artery disease. It is effective in the short term; however, in-stent restenosis (ISR) limits long-term success. Surveillance with duplex ultrasound (DUS) can identify patients who develop ISR leading to early reintervention, but data to support this practice is sparce. The purpose of this study was to evaluate whether surveillance and subsequent reintervention improves outcomes in patients with SFA stents. METHODS: A single-center, retrospective study was performed with patients undergoing SFA stenting between 2005 and 2020 who had a follow-up with DUS. Five groups were identified based on the presence of ISR on DUS (ISR vs no ISR [NISR]), recurrence of symptoms (symptomatic [SX] vs asymptomatic [ASX]), and if any reintervention was performed (reintervention [R] vs no reintervention [NR]): (1) ISR+SX+R; (2) ISR+SX+NR; (3) ISR+ASX+R; (4) ISR+ASX+NR; and (5) NISR+NR. The primary endpoint was amputation-free survival, and the secondary endpoint was patency. Predictors of mortality and surveillance were identified by multivariable logistic regressions and Cox multivariate regression models. Survival curves were presented as Kaplan-Meier plots using log-rank test for subgroup comparison. RESULTS: Two hundred fifty-seven patients were included in the analysis. The indication for intervention was claudication in 28% and chronic limb-threatening ischemia in 72%. A total of 161 patients (63%) underwent reintervention for ISR. Of patients who had restenosis on DUS, those who were symptomatic and did not undergo reintervention (ISR+SX+NR) did the worst, with 50% amputation rate. In contrast, those who were asymptomatic but did undergo reintervention (ISR+ASX+R) had the lowest amputation rate of 13%. Active smoking was a predictor of both loss of patency and amputation (1.72; 95% confidence interval [CI], 1.00-2.98; P = .050; 3.55; 95% CI, 1.53-8.25; P = .003). Post procedure dual antiplatelet therapy had a positive association with limb salvage (hazard ratio [HR], 0.23; 95% CI, 0.09-0.58; P = .001), whereas diabetes (HR, 2.61; 95% CI, 1.21-6.01; P = .019), stent occlusion (HR, 17.0; 95% CI, 5.93-63.1; P < .001), and chronic limb-threatening ischemia presentations (HR, 4.31; 95% CI, 1.86-11.7; P=.002) were negatively associated with limb salvage. CONCLUSIONS: Routine surveillance DUS and subsequent reintervention on ISR after SFA stenting is associated with improved patency and amputation-free survival. Surveillance DUS should be routine for patients after stenting, with reintervention strongly considered if ISR is identified for both symptomatic and asymptomatic.

RESUMO

BACKGROUND: Kommerell's diverticulum (KD) with a right aortic arch (RAA) and aberrant left subclavian artery (aLSCA) is a rare congenital anomaly of the aortic arch. Treatment is not well defined due to its uncommon presentation, with rupture and dissection risk rates of up to 53%. CASE SUMMARY: A 54-year-old male with a history of chronic obstructive pulmonary disease (COPD) and hypertension presented with difficulty breathing during exercise without dysphagia. Follow-up computerized tomography angiogram (CTA) revealed the presence of a RAA and aLSCA arising from the descending thoracic aorta with an adjacent 58 × 41-mm KD and tracheal and esophageal displacement. Due to the size of the KD, risk of rupture, unsuitable anatomy for total endovascular aortic repair (EVAR), and high COPD burden, the patient was planned to undergo a hybrid surgical repair. Left common carotid (LCCA) artery to LSCA bypass, full aortic debranching, LSCA embolization and percutaneous thoracic endovascular aortic repair (TEVAR) were performed. Successful device position and exclusion of the diverticulum and aneurysmal aorta were observed after completion thoracic aortogram. 18-month follow-up CTA demonstrated patency of the LSCA to LCCA bypass graft and arch vessel branches, as well as stable exclusion of the KD. Persistence of a type II endoleak originated at the right first posterior intercostal artery has been noted and is being followed conservatively since no sac growth has occurred. CONCLUSION: We highlight the presence of a KD with RAA and aberrant subclavian artery, a rare congenital anatomic variation of the aortic arch with complex anatomy. Surgical planning must be individualized according to comorbidities and anatomical variations identified on imaging and 3D reconstructions.

RESUMO

Endovascular treatment options for vascular injury in pediatric patients are quite limited owing to concerns regarding long-term durability and the lack of devices suitable for the pediatric anatomy. However, in rare circumstances, open surgical therapy will not be an option, and patients will require unconventional endovascular solutions for lifesaving or limb-saving therapies. In the present report, we describe an endovascular treatment of a pediatric patient for whom initial surgical management of a blunt abdominal aortic injury had failed, with subsequent development of an aortic pseudoaneurysm. A 10-year-old girl had presented after a high-speed motor vehicle accident with a seatbelt sign. Multiple abdominal injuries were identified, including blunt aortic injury, significant devitalization of the small bowel, colonic perforation with fecal contamination, multiple lumbar spine fractures, and pulmonary contusions. The patient developed bilateral lower extremity ischemia from the aortic injury and had initially undergone open repair. One month later, the patient had developed a pseudoaneurysm of the aorta near the aortic bifurcation. Because of the hostile abdomen and ensuing short gut syndrome, the pseudoaneurysm was managed using endovascular techniques. The limb of an Excluder internal iliac branch endoprosthesis (W.L. Gore & Associates, Flagstaff, AZ) was used as the endograft. The aortic bifurcation was raised and reconstructed using four Viabahn self-expanding stents (W.L. Gore & Associates). The completion angiogram showed complete resolution of the pseudoaneurysm. The follow-up computed tomography angiogram showed widely patent stent grafts with complete resolution of the pseudoaneurysm. Endovascular management of traumatic vascular injuries in pediatric patients is feasible. The likelihood of reintervention in the future is high with patient growth. However, it is a viable option in lifesaving or limb-saving situations in which open repair is high risk.

RESUMO

INTRODUCTION: Approximately one-third of surgical patients exhibit low health literacy, and 39% of our patients are primary Spanish speakers. We first evaluated the current content of our arteriovenous fistula/graft discharge instruction (DCI) templates. Using the Plan-Do-Study-Act cycle quality improvement methodology, we then aimed to optimize the readability and formally translate new DCI and evaluate usage and inappropriate bouncebacks following implementation. METHODS: Current arteriovenous fistula/graft template content was reviewed by the literacy department for readability and vascular faculty for completeness and accuracy. The literacy department edits were categorized by word choice, added/removed content, format change, and grammatical errors. Two vascular surgeons rated completeness and accuracy on a Likert scale (1-5). Retrospective chart review was performed for telephone calls and emergency department bouncebacks for 3 mo flanking new DCI implementation. RESULTS: Of the 10 templates, all were in English and word count ranged from 192 to 990 words. Despite each template including all necessary subcategories, the median number of edits per 100 words was 9.2 [7.0-9.5]. Approximately half of the edits (5.4 [5.1-5.5]) were word choice edits. Overall, experts rated completeness at 3.9 [3.2-4.2] and accuracy at 4.0 [3.7-4.1]. Highest template utilization occurred during post-implementation months 1 (90%) and 3 (100%) with orientation sessions. There was a significant increase in concordant Spanish DCI use (P < 0.01) and no inappropriate bouncebacks after implementation. CONCLUSIONS: Our study demonstrated notable variability in the content and readability of our vascular access instruction templates. New DCI had strong usage and language concordance; continued use may decrease bouncebacks.
