Notable milestones in the treatment of vascular lesions have been achieved over the past century. Many cutaneous vascular lesions can be successfully treated with lightbased devices. In this review, we will discuss the treatment of port-wine birthmarks, lymphatic malformations, infantile hemangiomas, rosacea, venous lakes, pyogenic granulomas, cherry angiomas, and angiofibromas using lasers, total reflection amplification of spontaneous emission of radiation, intense pulsed light, and photodynamic therapy. In addition, for several of these diagnoses, we will review medical therapies that can be combined with light-based devices to provide enhanced results...

BACKGROUND: Spinal vascular malformations as a group are rare entities and coexistence of spinal arteriovenous malformation in or around the spinal dysraphism is extremely rare. CASE DESCRIPTION: Herein, we report two cases of combined spinal dysraphism and vascular malformations of the spinal cord. The first case is an arteriovenous malformation located in a filum terminale lipoma fed by the artery of filum terminale. This case was managed by multiple endovascular embolizations followed by surgery...

Several studies have demonstrated zebrafish as a useful high-throughput in-vivo model to study the effects of cigarette smoke on early development. It has been shown previously that exposure of zebrafish to cigarette smoke total particulate matter (TPM) leads to several adverse physiological aberrations, including heart deformities and improper angiogenesis. Consequently, this study investigated the effects of TPM on cardiovascular development in zebrafish that were exposed to increasing concentrations of TPM based upon nicotine content from 6h post fertilization (hpf) up to 72hpf...

BACKGROUND: In a variety of animal species, hyperthermia in pregnancy has been recognized as teratogenic. Hyperthermia interferes with protein synthesis via heat-shock proteins, which can entail membrane disruption, cell death, vascular disruption, and placental infarction. This can induce severe fetal malformations or death. Fever during pregnancy, especially during embryogenesis, has also been associated with congenital malformations in human offspring. The purpose of this large cohort study of clinically recognized pregnancies was to investigate whether fever during first trimester was associated with an increased risk of congenital malformations in the offspring...

INTRODUCTION: Venous malformations (VMs) are ubiquitous, low-flow vascular anomalies known to be occasionally painful due to thrombotic episodes within the lesion. The prevalence of superficial or deep vein thrombosis is unclear. METHODS: A cross-sectional study among outpatients aged ≥ 12 years with pure VMs was performed, quantifying the prevalence of thrombosis by screening all patients with compression ultrasonography (CUS). Additionally, we evaluated whether coagulation alterations were related to thrombosis observed with CUS...

Vascular anomalies are divided into tumors and malformations based on their clinical and cytologic attributes. Vascular malformations are further subcategorized as low-flow lymphatic, venous, capillary, or mixed lesions and as high-flow arteriovenous malformations. Treatment is reserved for vascular anomalies that are symptomatic or cosmetically disfiguring, and surgical and nonsurgical treatment options are widely varied with variable outcomes.

Vascular tumors are benign neoplasms, which result from proliferating endothelial cells. These lesions present during infancy or childhood, may affect any location, and exhibit postnatal growth. Local complications include bleeding, tissue destruction, and pain whereas systemic sequelae include thrombocytopenia, congestive heart failure, and death. Vascular tumors should be differentiated from vascular malformations, which present at birth, have a quiescent endothelium, and grow in proportion to the child. Together, vascular tumors and malformations comprise the field of vascular anomalies...

The detection of somatic, activating genetic mutations to underlie development of vascular tumors and malformations led to a better understanding of their pathophysiology. Proteins encoded by the detected mutated genes activate the two major signaling pathways, also involved in cancer: the RAS/MAPK/ERK pathway and/or the PI3K/AKT/mTOR pathway. This gives a strong basis for studies to repurpose cancer therapeutics to patients with vascular tumors and malformations.

Vascular malformations affect the craniofacial skeleton in many ways, depending on the type of the lesion and its location. The lesions may exert a mass effect and cause thinning or thickening of the bone or cause expansion from direct bony infiltration. Orthognathic surgery can be used to correct any malocclusion or open bite deformities after the soft tissues are addressed.

Tristan Klosterman, Teresa M O
Vascular malformations may affect nearly all aspects of the upper airway. Each type of malformation has a characteristic pattern of disease. These lesions may be focal or diffuse, and require directed management strategies. Physicians treating these entities should have a high level of suspicion to consider airway evaluation even in the absence of overt symptoms. However, cutaneous head and neck venous malformations or other lesions affecting the lips, oral cavity, or tongue can herald the presence of coexisting airway lesions...

Capillary malformations (CMs), also known as port-wine stains, are the most common type of congenital vascular malformations. Facial CM often occurs with a quasidermatomal distribution according to the sensory trigeminal nerve distribution. With time, these lesions darken progressively, and soft tissue hypertrophy, bony hypertrophy, and/or nodule formation can develop. Multiple treatments for CM have been reported. However, the mainstay and gold standard therapy for facial or aesthetically sensitive CM is still the pulsed dye laser treatment...

Extracranial arteriovenous malformations (AVMs) are complex vascular malformations to diagnose and treat. They are comprised of congenitally derived arteriovenous shunts with chronic vascular expansion, collateralization, and infiltration of local tissue. Their cause remains unclear, but new genetic and molecular clues are emerging. They may present at any age following an early quiescent period. Diagnosis is based on vascular staining, soft tissue expansion, progressive growth, warmth, and pulsations. Focal lesions can be cured, whereas diffuse AVMs demonstrate highly recidivistic disease...

Vascular malformations are congenital anomalies of the vascular and/or lymphatic system that affect the head and neck region. The most common treatment options are sclerotherapy, laser therapy, surgery, and embolization. Because vascular malformations are variable in type, size, extent, and location, it is a challenge to select methods for evaluation of treatment outcome. Without standardized outcome reporting, it is difficult to compare and combine scientific evidence to support therapeutic decision making...

Accurate histopathologic description in correlation with clinical and radiological evaluation is required for treatment of vascular anomalies, both neoplastic and malformative. It is important to examine current clinical, histologic, and immunophenotypical features that distinguish the major types of congenital and perinatal vascular anomalies affecting the head and neck. General discussions of pathogenesis and molecular diagnosis must also be taken into account. This article provides an overview of the features that distinguish the major types of congenital and perinatal vascular anomalies affecting the head and neck, and summarizes the diagnostic histopathologic criteria and nomenclature currently applied to these lesions...

Venous malformations are slow flow dysplastic lesions, constituted by a vascular nest without arterial or capillary connections, more or less independent of the normal venous anatomy and circulation. In certain cases a treatment is required for symptom relief or for natural complications management. The percutaneous sclerotherapy under ultrasound guidance is increasingly used as an effective and mini-invasive option, allowing obtaining very good results with minor side effects. Several substances have been used with different efficacy and side effects rate...

BACKGROUND AND PURPOSE: Transitional venous anomalies (TVAs) are rare cerebrovascular lesions that resemble developmental venous anomalies (DVAs), but demonstrate early arteriovenous shunting on digital subtraction angiography (DSA) without the parenchymal nidus of arteriovenous malformations (AVMs). We investigate whether arterial spin labeling (ASL) magnetic resonance imaging (MRI) can distinguish brain TVAs from DVAs and guide their clinical management. METHODS: We conducted a single-center retrospective review of patients with brain parenchymal DVA-like lesions with increased ASL signal on MRI...

Background: Dural arteriovenous fistulas (DAVF) are unusual intracranial vascular malformations consisting of anomalous connections between meningeal arteries and dural sinuses or the veins that pass through them. They have variable clinical presentation and prognosis, which depend on their location and venous hemodynamics. Treatment is based on the closure of the abnormal connections, which is usually conducted via arterial and/or transvenous endovascular techniques. Case Description: We present a male patient who complained of headaches and left-sided pulsatile tinnitus due to DAVF from the external carotid artery branches draining directly into the ipsilateral sigmoid sinus...

Diffuse neurofibroma is a rarely encountered subtype of neurofibroma but the most common to be misdiagnosed. Its imaging appearance is very similar to that of a vascular malformation, and it is often labelled one until a biopsy proves it to be otherwise. The infrequency of its association with neurofibromatosis makes it a rare and difficult diagnosis. Here, we report the case of a 16-year-old girl who presented with the complaint of a gradually progressive swelling around the right ankle and heel, which was initially diagnosed as a case of a vascular malformation...

Crossed fused renal ectopia is a rare congenital anomaly, and is mostly detected incidentally. A 45-year-old man, during investigation for recurrent abdominal pain, was found to have an empty left renal fossa and right crossed renal ectopia with fusion on ultrasonography. In the present case, there were no abnormalities and/or alteration of the renal function. Abdominal tomography scan with contrast medium confirmed the diagnosis. Ectopic kidney is often associated with other abnormal situations such as agenesis, vascular malformation, incontinence, a palpable abdominal mass, urinary tract infection, high incidence of stone formation, and genital anomalies...
