ABSTRACT
PURPOSE: To evaluate the use of inframalleolar access for endovenous ablation when treating advanced venous disease with nonthermal nontumescent (NTNT) techniques. METHODS: This single-center retrospective study included 109 patients with advanced venous disease, treated using inframalleolar access between May 2018 and March 2020. NTNT techniques included ClariVein (Merit Medical Systems, South Jordan, Utah) and ScleroSafe (VVT Medical, Kefar Sava, Israel). Outcomes measured were postprocedure pain, leg edema, ulcer healing and recurrence rates, and venous insufficiency recurrence. RESULTS: Seventy-seven patients (70%) were treated with ClariVein and 32 (30%) with ScleroSafe. Postprocedure pain score (range, 0-10) after 1 week decreased from a preprocedure median of 5 (interquartile range, 3-6) to 1 ((interqartiel range, 0-2) (P = .0001). Complete wound healing was achieved in 38 patients (43.7%) after 30 days and in 71 patients (81.6%) after 90 days. One patient developed an ulcer recurrence and six developed venous insufficiency recurrence. There was no reported nerve or skin injuries. CONCLUSIONS: NTNT ablation techniques using inframalleolar access are effective and safe without risk of nerve damage. Their use facilitates ulcer healing and limits pain in patients with advanced disease.

Direct oral anticoagulants (DOACs) are increasingly prescribed in treatment of cancer-associated thrombosis, but limited data exist regarding safety of DOACs in patients with brain metastases. We aimed to determine the incidence of intracranial hemorrhage (ICH) in patients with brain metastases receiving DOACs or low-molecular-weight heparin (LMWH) for venous thromboembolism or atrial fibrillation. An international 2-center retrospective cohort study was designed. Follow-up started on the first day of concomitant anticoagulation and brain tumor diagnosis. At least 2 brain imaging studies were mandated. The primary outcome was the cumulative incidence of any spontaneous ICH at 12-month follow-up with death as a competing risk. Major ICH was defined as spontaneous, ≥10 mL in volume, symptomatic, or requiring surgical intervention. Imaging studies were centrally reviewed by a neuroradiologist blinded for anticoagulant type. PANWARDS (platelets, albumin, no congestive heart failure, warfarin, age, race, diastolic blood pressure, stroke) score for prediction of ICH was calculated. We included 96 patients with brain metastases (41 DOAC, 55 LMWH). The 12-month cumulative incidence of major ICH was 5.1% in DOAC-treated patients and 11.1% in those treated with LMWH (hazard ratio [HR], 0.45; 95% confidence interval [CI], 0.09-2.21). When anticoagulation was analyzed as a time-varying covariate, the risk of any ICH did not differ between DOAC- and LMWH-treated patients (HR, 0.98; 95% CI, 0.28-3.40). PANWARDS score was not associated with ICH risk. This international 2-center study suggests comparable safety of LMWH and DOACs in patients with brain metastases.
