Recurrent Systemic Urticaria Following Cyanoacrylate Closure for the Treatment of Incompetent Saphenous Veins

Annals of phlebology.2024;22(2):91-93. doi:10.37923/phle.2024.22.2.91

The VenaSeal (Medtronic) cyanoacrylate closure system is a non-thermal non-tumescent technique for ablating saphenous veins using a proprietary n-butyl cyanoacrylate. A potential side effect is an allergic reaction to the cyanoacrylate. It is widely known that most reactions occur locally around the saphenous vein at the site of the procedure, while systemic allergic reactions are exceedingly rare. We present the case of a 31-yearold woman who was treated with cyanoacrylate closure and subsequently developed recurrent systemic urticaria. There were no notable issues until one week after the procedure, but on postoperative day (POD) 8, itching and swelling accompanied by a rash appeared at the site of the procedure, with the rash spreading to the abdomen. Following this, a whole body rash and wheezing occurred. While symptoms improved with the use of steroids and antihistamines, the systemic rash intermittently reappeared after discontinuation of the medication.

Myeonghyeon KO ; Song-Yi KIM

Annals of phlebology.2024;22(2):86-90. doi:10.37923/phle.2024.22.2.86

Pulmonary embolism (PE) that occurs in patients with severe chronic obstructive pulmonary disease (COPD) can often result in acute exacerbation. Immediate intervention for them is required to prevent acute exacerbations and reduce mortality. A 72-year-old man with severe COPD developed deep vein thrombosis with PE and worsened despite anticoagulant therapy and mechanical ventilation. Thrombolysis was contraindicated due to a history of gastric bleeding 3 weeks ago. He had a pulmonary embolism severity index (PESI) score of 272, placing him in the very high-risk group, with a 30-day mortality rate of 10.0%–24.5%. Mechanical thrombectomy was performed using AngioJet® Solent catheter to remove the thrombus obstructing the right middle and lower lobe pulmonary arteries. The patient improved without complications and was discharged. PE in severe COPD requires immediate intervention due to the higher severity of symptoms compared to the general population, and the use of AngioJet ® Solent catheter may be an effectively alternative modality of treatment.

Insoo PARK ; Sujin PARK

Annals of phlebology.2024;22(2):77-81. doi:10.37923/phle.2024.22.2.77

Objective: Flebogrif® is a new mechanochemical ablation (MOCA) technique for treating chronic venous disorders (CVD), with limited studies available. This study provides early clinical outcomes from its use in South Korea. Methods: A retrospective analysis was conducted on 55 patients treated with Flebogrif®at a Charm Vascular Clinic in Seoul. Mechanical injury combined with foam sclerosant (2% STS and CO 2 ) was applied to 113 saphenous veins. Primary outcomes were anatomical success at 1 and 3 months, with secondary outcomes included adverse events, pain scores, rVCSS score, CIVIQ14 score, time to return to normal activities and foam sclerosant dosages. Results: The anatomical success rate were analyzed as 97.3% at 1 month and 96.9% at 3 months. Adverse events were mild, with no occurrences of severe events such as paresthesia or deep vein thrombosis (DVT). The mean time returned to normal activities was 1.07±0.42 days. Notably, Flebogrif® allowed treatment of multiple veins without increased risk, averaging a foam sclerosant volume of 15.85±5.71 cc per procedure. rVCSS and CIVIQ14 scores showed a statistically significant decrease from the initial scores. Conclusion Flebogrif® shows promise as an effective and safe treatment for CVD, achieving comparable results to other methods with potential cost benefits. Further studies are recommended for validation.

Hemodynamic Consideration of Thigh-Level Compression Stockings after Greater Saphenous Vein Ablation

Sangchul YUN

Annals of phlebology.2024;22(2):74-76. doi:10.37923/phle.2024.22.2.74

Compression stockings are widely utilized for various purposes in the management of patients with varicose veins. Their primary applications include alleviating swelling and edema, preventing the progression of varicose veins, minimizing post-operative bleeding, and occluding veins following surgical interventions. Various compression devices, such as compression bandages, elastic or non-elastic stockings, are also commonly employed. Graduated compression stockings are particularly favored both preand post-operatively for varicose vein treatment. These stockings exert higher pressure in the ankle and calf regions, with gradually diminishing pressure towards the thigh.However, concerns remain regarding the efficacy of this reduced pressure in adequately compressing veins in the thigh region. Moreover, silicone band products designed to prevent slipping often induce significant skin side effects, suggesting their avoidance in clinical practice. For these reasons, below-knee compression stockings may be recommended, as they enhance the calf muscle pump function and improve wearing comfort.In cases where thigh-high stockings are necessary, the addition of targeted pads to the affected vein areas may be beneficial in increasing localized pressure to occlude target vein.

Clinical Implications of Venous Hypertension in the Management of Chronic Venous Disease

Sangchul YUN

Annals of phlebology.2024;22(2):71-73. doi:10.37923/phle.2024.22.2.71

In the patient with chronic venous disease, venous hypertension occur which result in inability of calf pumps and conduits in the venous system to maintain a normal pressure and normal flow towards the heart. Venous hypertension is caused by venous reflux, obstruction, a combination of reflux and obstruction or arterio-venous fistula. Compensation for obstruction are the development of collateral vein circulation and lymphatic drainage. The clinical symptoms and signs are a result of the venous hypertension and the lack of compensation. Inability to quantitate these factors in individual patients contributes to an incomplete understanding of the pathophysiology, leading to controversies and significant challenges in managing chronic venous disease.

Chang Sik SHIN ; Ji Il KIM

Annals of phlebology.2024;22(2):57-60. doi:10.37923/phle.2024.22.2.57

Varicose veins are a prevalent vascular disorder affecting a significant portion of the global population, leading to reduced quality of life and potential health risks if left untreated. Traditional treatments, while effective, are often invasive and associated with complications and prolonged recovery times. To provide a comprehensive review of High-Intensity Focused Ultrasound (HIFU) as a non-invasive treatment modality for varicose veins, discussing its mechanism of action, clinical applications, efficacy, advantages, limitations, and future prospects. A systematic literature review was conducted using databases such as PubMed, Scopus, and Web of Science, focusing on studies published up to October 2023 that evaluated the use of HIFU in varicose vein treatment. HIFU demonstrates high efficacy in vein closure rates, comparable to traditional endovenous therapies, with the added benefits of being completely non-invasive, minimizing patient discomfort, and reducing recovery times. Clinical studies report closure rates exceeding 95% with low complication rates. Limitations include longer treatment durations and limited availability due to high costs. HIFU emerges as a promising noninvasive alternative for the treatment of varicose veins, offering significant advantages over traditional therapies. Further advancements and broader accessibility may position HIFU as a standard treatment option in the future. Additionally, we discuss the potential application of HIFU for treating superficial venous lesions such as telangiectasia.

Hyangkyoung KIM

Annals of phlebology.2024;22(2):52-56. doi:10.37923/phle.2024.22.2.52

Non-thermal, non-tumescent (NTNT) techniques for varicose vein treatment have gained significant attention as alternatives to traditional thermal ablation methods, providing less invasive options with fewer complications and less downtime. This review examines the efficacy, safety, and patient outcomes associated with NTNT modalities such as cyanoacrylate adhesive closure, mechanochemical ablation (MOCA), and polidocanol endovenous microfoam (PEM). Recent trials suggest these NTNT methods achieve closure rates comparable to thermal methods, with lower complication rates and improved patient satisfaction. Key metrics from recent studies, including technical success, recurrence rates, and complication profiles, underscore the promise of NTNT techniques as first-line therapies. Findings also indicate variability in recurrence rates and complication profiles depending on vein anatomy and patient characteristics. In conclusion, NTNT approaches represent a promising evolution in varicose vein treatment, warranting further studies to standardize outcomes and optimize patient selection.
