RESUMEN
PURPOSE: To identify risk factors for rupture, and to determine outcomes of endovascular treatment of median arcuate ligament (MAL) compression-related visceral artery aneurysms (VAAs). METHODS AND MATERIALS: A retrospective review of patients who presented with MALC-related VAAs was performed from 1999 to 2021. A total of 21 patients (12 men) and 39 VAAs associated with MAL compression were encountered (mean age, 59 years). Imaging studies were reviewed for the number, morphology/size, and recurrence of aneurysms. Statistical analysis was performed to identify risk factors for rupture. RESULTS: Ten patients presented with acute rupture, and 12 patients were symptomatic with nonspecific abdominal pain. Twenty-two aneurysms were fusiform in morphology and 17 aneurysms were saccular in morphology. Of the 14 aneurysms that presented with acute hemorrhage, 12 (86%) were fusiform in morphology (odds ratio, 9.0; P < .01). The mean aneurysm size was 1.3 cm, and the mean ruptured size was 0.6 cm. Thirty-one aneurysms were treated by endovascular techniques, and technical success was achieved in all cases. Fourteen patients were found to have an Arc of Buhler. No procedure-related adverse events occurred. No patient underwent surgical ligament release. The mean time of follow-up was 3.2 years, and no aneurysms recurred after endovascular treatment. CONCLUSIONS: MAL compression-associated VAAs are an important clinical entity that should be treated even at small sizes, particularly if they are fusiform in morphology. Endovascular therapy is safe and feasible and results in durable aneurysm exclusion.

Inferior vena cava filters (IVCFs) are an established alternative for protection from thromboembolism when anticoagulation fails or is contraindicated. Before the creation of retrievable IVCFs, patients received filters that were permanent or designed without standardized retrieval options. Although these filters were implanted for prolonged protection, chronic vena caval occlusion and post-thrombotic syndrome are potential sequelae. We present a 53-year-old patient with a Mobin-Uddin permanent IVCF placed 42 years prior complicated by acute iliocaval thrombosis following more than 40 years of filter dwell time. She was successfully treated with thrombolysis, thrombectomy, endobronchial forceps assisted IVCF removal, and iliocaval stent reconstruction.

Chronic venous insufficiency is one of the most common benign diseases in America. For treatment, minimally invasive techniques have become the first-line option. The literature shows that these procedures are well tolerated and work effectively without leaving the patient with unaesthetic operative scars. We discuss the case of a patient who developed two right lower extremity neuromas as a rare complication following endovenous laser ablation and microphlebectomy procedures for the treatment of varicose veins. Ultrasound is the preferred imaging modality for the visualization and diagnosis of a neuroma and should be performed in post-phlebectomy patients with severe and persistent sensory pattern disruption as neuroma formation can lead to significant complications for the patient.
RESUMEN
PURPOSE: To evaluate the efficacy/safety of an ophthalmic suspension of povidone-iodine (PVP-I) 0.6% and dexamethasone 0.1% in patients with acute adenoviral conjunctivitis. DESIGN: Multicenter, randomized, vehicle-controlled, double-masked trial. METHODS: Adults with a positive Rapid Pathogen Screening Adeno-Detector Plus test were randomized 1:1:1 to PVP-I 0.6%/dexamethasone 0.1%, PVP-I 0.6%, or vehicle, bilaterally 4 times daily for 5 days (days 1-5). Patients were evaluated on days 3, 6, and 12 (+1-day window). Efficacy measures included clinical resolution and adenoviral eradication. RESULTS: Overall, 144 patients were included in the efficacy analysis (PVP-I/dexamethasone, n = 48; PVP-I, n = 50; vehicle, n = 46). The proportion of patients with clinical resolution (primary study eye with last observation carried forward [LOCF]) at the day 6 visit was higher with PVP-I/dexamethasone (31.3%) than with vehicle (10.9%; P = .0158) and PVP-I (18.0%; P = nonsignificant). The proportion with adenoviral eradication (primary study eye with LOCF) was higher with PVP-I/dexamethasone than with vehicle at the day 3 (35.4% vs 8.7%; P = .0019) and day 6 (79.2% vs 56.5%; P = .0186) visits and vs PVP-I (day 3 visit, 32.0%; day 6 visit, 62.0%; each P = nonsignificant). Treatment-emergent adverse events (AEs) occurred in 69.0% (vehicle), 62.7% (PVP-I), and 53.4% (PVP-I/dexamethasone) of patients in the safety dataset. Discontinuation owing to AEs occurred in 37 patients (vehicle, n = 16; PVP-I, n = 12; PVP-I/dexamethasone, n = 9). CONCLUSION: PVP-I/dexamethasone appeared safe and well tolerated, and significantly improved clinical resolution and adenoviral eradication in patients with acute adenoviral conjunctivitis.
