There are no prospective studies of pregnancies for the diseases studied here in (Heredity Hemorrhagic Telangiectasia, Marfan syndrome, primary lower limb lymphedema, superficial arteriovenous malformations, and cerebro-spinal arteriovenous malformations) although complications of these can present life-threatening health problems for the mother and her baby. The purpose of this National prospective study is to obtain greater insight into obstetrical complications associated with rare maternal vascular genetic disorders in order to improve prevention and to reduce risk of death. In this context, experts and patient associations consider that there is a need to make real progress in the formulation of recommendations based on scientific data.
The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer
Proposed Study: Treatment protocol for the use of the topical Rapamycin/Sirolimus for Complicated Vascular Anomalies and other susceptible lesions 1. Aim The aim of this treatment study is to evaluate the benefit and tolerability of topical sirolimus applied to cutaneous vascular anomalies in pediatric patients. The primary end point will be individually determined based on improvement in lesional clinical characteristics over baseline 2. Rationale for topical sirolimus use in VA The rationale for the use of topical sirolimus is to minimize these potential side effects and risks. Data for the use of topical sirolimus for vascular anomalies at this time are anecdotal and case reports only. As such, this prospective protocol seeks to determine the effectiveness and tolerability of topical sirolimus on patients with vascular anomalies that have a cutaneous component. 3. Experimental design This is an open-labeled efficacy trial with the aim to determine if topical sirolimus can be safe and efficacious in treating the cutaneous component of complicated vascular anomalies. Patients who meet eligibility criteria with a diagnosis of vascular anomaly (VA) with cutaneous component will be offered treatment with the investigational topical sirolimus. Patients will receive topical sirolimus therapy for a total of six months and will be monitored regularly at the research site for clinical response. Response will be based on pre-determined clinical criteria. Patients will be removed from study if there is no response at three months after initiation of therapy. Clinical response will be defined as improvement in measurable parameters defined at the time of initiation of therapy. These include 1. Size of lesions, measured in two parallel longest diameters 2. Flattening of lesion 3. Number of vesicles 4. Episodes of superinfection or bleeding 5. Improvement in pain 4. Drug Information The topical sirolimus formulation will be made at a concentration of 1% sirolimus ointment. Bulk sirolimus powder will be compounded in a liposomal base in a GMP level pharmaceutical company. This base will enhance drug penetration into the skin. It ensures adequate adhesion to the application area and a low degree of systemic absorption. Due to limited absorption only mild side effects are expected.
The purpose of this study is to develop a standardized assessment for patients treated for venous malformations (VM). Venous malformations result from the abnormal development of veins which may result in pain, swelling, bleeding, functional impairment, disfigurement, and psychological distress. The impact of VM on patient quality of life varies based on the location and size of the malformation. A patient reported outcome (PRO) is a patient's own account of patient's health condition. PRO measures are valued to clinicians, as many treatment effects are known only to the patient. No studies to date have analyzed the validity of existing PRO measures for VM patients. Current assessment does not include all symptoms or take in to account the relevance of VM location. Past studies show a discrepancy between treatment outcomes reported by patients and physicians. Therefore, there is a need to develop VM-specific PROs to better understand the effectiveness and benefits of treatment for VM.
Congenital vascular anomalies are uncommon and belong to the group of rare diseases.These vascular malformations can cause serious complications including obstruction of vital organs and their function, recurrent infection and significantly reduced quality of life of persons affected.Treatment options range from conservative to surgical extirpation or intralesional embolisation/sclerosis. Unfortunately, this is often not enough. Many patients still have complaints like severe pain and invalidation due to the lymphatic or venous malformation making a normal functional life impossible. Recent case reports mention the positive effects of refractory patients with Sirolimus. Sirolimus, also known as rapamycin, is currently the only FDA-approved mammalian target of rapamycin (mTOR) inhibitor.
Cutaneous microcystic lymphatic malformations (CMLMs) are rare conditions of children and adults resulting from abnormal embryologic development of lymphatic vessels. They present as clusters of vesicles full of lymph and blood of various extent. They ooze and bleed, inducing maceration, esthetic impairment, scars, pain, bacterial infections and impaired quality of life. Currently, treatments for CMLMs are disappointing, and their management is challenging. Sirolimus is an inhibitor of mammalian target of rapamycin (mTOR), a serine/threonine protein kinase involved in cell growth and proliferation, cellular metabolism, autophagy and angio-lymphangiogenesis. Topical sirolimus, known to be efficient and well tolerated in cutaneous angiofibromas linked to tuberous sclerosis, has recently been reported effective in few reports of patients with CMLMs. The objective of this trial is to compare the efficacy and safety of a 12-week application of 0.1% topical sirolimus versus topical vehicle in CMLMs in children and adults.

The low-flow malformations include venous and lymphatic malformations. The malformation often affects the skin and can extend deep to the muscles and bone, as well as to deep organs. Children with low-flow vascular malformation and their family have difficulty living with their illness and have an impact on their life quality. In this context, the aim of the study is to develope life quality test for the children between 11 to 15 years old.
The purpose of this study was to investigate whether the balanced fluids therapy change plasma osmolality in neurosurgical procedures due to brain tumors, meningeomas and arterio-venous malformation.
