Abstract
PURPOSE Patients with arteriovenous malformations (AVMs) have a lower health-related quality of life (QoL) than the general population. QoL assessment of patients with peripheral AVMs after endovascular treatment is scarce in the literature. Radiologic and clinical outcomes are not always correlated in vascular malformation treatment. This study aimed to investigate the relationship between clinical outcomes, QoL, and angiographic outcomes. MATERIALS AND METHODS Patients with peripheral AVM that underwent endovascular treatment between January 2009 and December 2021 in a single center were retrospectively evaluated. Patients' characteristics (age, sex), AVM characteristics (Schobinger classification, location, angiographic architecture), previous treatment, treatment characteristics (type of endovascular approach, embolizing agent and number of sessions), percentages of angiographic response, complications, and recurrence were evaluated. The angiographic architecture was evaluated according to the Yakes classification. The questionnaire was applied for evaluation of clinical response and QoL. Patients older than 12 years and those who can be contacted were included in clinical and QoL analysis. Clinical response was defined as improvement in the patient's most important pretreatment symptom. Treatment response was defined as clinical response plus >50% angiographic response. RESULTS Eighty-six patients (41 males [47.7%], 45 females [52.3%]) were included in angiographic analysis. The mean age was 28.44±12.99 years (range=5-61). Forty-three patients (50%) had previous treatment. The median number of sessions was 2 (range 1-15, InterQuartile Range [IOR]=2). Sixty-one patients (30 males [49.2%], 31 females [50.8%]) were included in clinical analysis. The clinical response rate was 73.8%, 95% confidence interval (CI) [0.60, 0.84]. The treatment response rate was 45.9%, 95% CI [0.33, 0.59]. The complication rate was 8.2%. Before treatment, 48 patients (78.7%) reported a negative impact on their QoL. Thirty-three of 48 patients (68.8%) reported improvement on their QoL after treatment. Higher Schobinger stages were related to a negative impact on QoL before treatment (p<0.01). Yakes types were not related to QoL (p=0.065). Clinical response was related to improvement on QoL after treatment (p<0.01). Angiographic and treatment responses were not related to improved QoL after treatment (p=0.52 and p=0.055, respectively). CONCLUSION Angiographic architecture and outcomes were not always reflected in QoL after endovascular treatment. CLINICAL IMPACT This study's findings will help clinicians with what to focus on in AVM treatment and how to monitor patients with peripheral AVM after endovascular treatment. Rather than relying too much on the angiographic response, patients should be checked for symptoms and quality of life improvement. No clear data in the literature regarding the applicability of the Yakes Classification in patients with previous treatment. This study questioned the applicability of the Yakes Classification in patients with previous treatments. In this study, type 4 AVMs were more common in patients with previous treatment.

Abstract
Congenital vascular malformations (CVMs) are the result of an aberrant development during embryogenesis. Although these lesions are present at birth, they are not always visible yet. Once symptomatic, patients suffer from pain, bleeding, ulcers, infections or lymphatic leakage, depending on the subtype of vessels involved. Treatment includes conservative management, surgery, sclerotherapy, embolization and pharmacological therapy. The clinical presentation varies widely and treatment can be challenging due to the rarity of the disease and potential difficulties of treatment. This review gives an overview of the historical developments in diagnosis and classification and exposes the key elements of innovations in the past decades on the identification of genetic mutations and personalized treatment. These advances in the field and a multidisciplinary approach are highly valuable in the optimization of clinical care aimed at both curing or stabilizing the CVM and pursuing physical and psychosocial wellbeing.

Abstract
BACKGROUND Arteriovenous malformations (AVMs) are developmental defects in the vascular system with abnormal connections between arteries and veins. A minority of AVMs are characterized by aggressive growth and continue to proliferate despite maximal surgical and interventional therapy. We report our outcomes with the use of thalidomide as the only UK specialist center adopting this novel approach for the management of AVMs refractory to conventional therapy. METHODS This was a retrospective case series which included only complex and proliferative AVM lesions (Schobinger grade III and IV). All patients prescribed thalidomide on a compassionate basis between September 2006 and August 2022 after attempts at embolosclerotherapy without satisfactory response were reviewed. RESULTS Eleven patients were included in our study. The median total duration of thalidomide use was 10 months. Two thirds of patients with pain (six of nine) reported an improvement, three quarters reported a reduction in swelling (six of eight) and all who presented with bleeding reported improvement in overall volume or frequency (four of four). Over the study period, 45% achieved a non-proliferative state with no further target vessel demonstrable on angiography. Mild, tolerable side effects such as fatigue were common (73%). There was only one major adverse reaction (neutropenia) necessitating cessation of therapy. CONCLUSIONS We can conclude that thalidomide is able to reduce the symptom burden for patients with complex and proliferative AVMs that were refractory to established treatment modalities. Adverse effects are common, but the benefit achieved from taking thalidomide in otherwise treatment resistant cases outweighs the risks, most of which are manageable.

Abstract
OBJECTIVE The study aimed to evaluate the early follow-up quality of life (QoL), pain and mental health of patients with congenital vascular malformation (CVM) from a variety of treatment options. METHODS All patients with CVM who received care and had follow-up between February 1st 2018 and January 31st 2020 were included. The health-related QoL, pain, and mental health were assessed with RAND Health Care 36-Item Short Form Survey (SF-36), visual analogue score for pain (VAS-P) and Hospital Anxiety and Depression Scale (HADS). Paired t-test was used for all analyses. p < .05 were considered significant. RESULTS In total, 110 patients with a mean age of 36.9 years were included in this study. In all patients following care, significant improvement was found in the bodily pain domain of SF-36 and VAS-P (both p = .01). This was largely driven by high-flow vascular malformation patients who responded better to embolo-sclerotherapy, which revealed significant improvement in the bodily pain domain of SF-36 (p = .002) and VAS-P (p = .02). Patients who received supportive treatment only reported significant improvement in mental health (p = .004) and social functioning (p = .03) domains of SF-36. Meanwhile, patients treated with embolo-sclerotherapy reported significant improvement only in VAS-P (p = .02). CONCLUSIONS This study concluded that the effects of care on early follow-up QoL, pain and mental health of patients with CVM were heterogenous. Future research should therefore, include larger sample size and longer term follow-up to understand the various factors that affect the QoL and mental health of these patients, as well as the holistic approaches to manage them.

Cardiovasc Eng Technol 2022; 13:234-246. [PMID: 34611845 PMCID: PMC9114032 DOI: 10.1007/s13239-021-00572-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 07/26/2021] [Indexed: 11/07/2022]
Abstract
PURPOSE Peripheral arteriovenous malformations (pAVMs) are congenital lesions characterised by abnormal high-flow, low-resistance vascular connections-the so-called nidus-between arteries and veins. The mainstay treatment typically involves the embolisation of the nidus, however the complexity of pAVMs often leads to uncertain outcomes. This study aims at developing a simple, yet effective computational framework to aid the clinical decision making around the treatment of pAVMs using routinely acquired clinical data. METHODS A computational model was developed to simulate the pre-, intra-, and post-intervention haemodynamics of a patient-specific pAVM. A porous medium of varying permeability was employed to simulate the sclerosant effect on the nidus haemodynamics. Results were compared against clinical data (digital subtraction angiography, DSA, images) and experimental flow-visualization results in a 3D-printed phantom of the same pAVM. RESULTS The computational model allowed the simulation of the pAVM haemodynamics and the sclerotherapy-induced changes at different interventional stages. The predicted inlet flow rates closely matched the DSA-derived data, although the post-intervention one was overestimated, probably due to vascular system adaptations not accounted for numerically. The nidus embolization was successfully captured by varying the nidus permeability and increasing its hydraulic resistance from 0.330 to 3970 mmHg s ml-1. The nidus flow rate decreased from 71% of the inlet flow rate pre-intervention to 1%: the flow completely bypassed the nidus post-intervention confirming the success of the procedure. CONCLUSION The study demonstrates that the haemodynamic effects of the embolisation procedure can be simulated from routinely acquired clinical data via a porous medium with varying permeability as evidenced by the good qualitative agreement between numerical predictions and both in vivo and in vitro data. It provides a fundamental building block towards a computational treatment-planning framework for AVM embolisation.
