Angiomatosis in the neck and mediastinum: an example of low-flow vascular malformations
European radiology, 2003
A rare case of multiple low-flow vascular malformations in the larynx, neck and mediastinum - reported as angiomatosis in the literature - is described. Sonography, CT, angiography and MRI were performed in our case, followed by laryngoscopy with biopsies to establish the diagnosis. The radiological features and a review of relevant literature are briefly discussed.
Histopathological analysis of vascular malformations
Phlebology: The Journal of Venous Disease
Objective To propose and develop a histopathological criteria to help diagnose vascular malformations. Methods All patients who underwent surgical resection and had a confirmed histopathological diagnosis of vascular malformations from 01 March 2018-26 February 2020 were included. A criteria based on 10 parameters was developed to help diagnose vascular malformations. Discrepancies between clinical and histopathological diagnosis were evaluated. Results A total of 18 cases were identified. There was a discrepancy between the clinical diagnosis and the initially reported histopathological diagnosis in 16 cases (88.9%). This was reduced to 7 (38.9%) and 6 cases (33.3%) with first and second time revised histopathological analysis using proposed criteria. Conclusions The discrepancy between clinical and histopathological diagnoses of vascular malformations has highlighted the requirement of an agreed criteria for histopathologists to help formulate their diagnosis. The proposed criteri...
Arteriovenous Malformations: Clinical Aspects and Surgical Results
International Journal of Cardiovascular and Thoracic Surgery, 2018
Arteriovenous malformations (AVM) are vascular malformations, broadband, formed of arterial and venous dysmorphic vessels interconnected directly without transition in a capillary bed. Arteriovenous malformation surgery is particularly demanding owing to the need to control bleeding. This is probably one of the most critical moments of arteriovenous malformation surgery. The purpose of this study is to analyzed the clinical aspects and evaluate the results of surgery in the treatment of these AVMs. This is a retrospective and descriptive study that took place in Dakar over a period from January 2004 to December 2017 on patients operated for arteriovenous malformations. The total number of our series was 11 cases. These AVMs represented 32.35% of all tumors and vascular malformations operated during this period. The mean age at surgery was 25 years old [1 year-56 years old]. A male predominance was noted with 7 male to 4 female (sex ratio 1.75). The average time of consultation was 8.3 years [1 months-30 months]. The main reason for consultation was the appearance of a mass in 11 cas. We noted a notion of traumatism or recent surgery were done in 4/11 before the onset of symptoms. The location of the lesions was at the head or the face (5 cases), neck (1 case), the upper member (2 cases), the lower member (3 cases). No multiple location were noted. After physical examination, two patients were classified Schobinger stage 1, stage 2 in 7 cases, 2 cases in stage 3. No patient was classified stage 4. The vascular Doppler ultrasound was performed in 10 cases (91%) and allowed to confirm the diagnosis in 10 cases. The CT angiography was performed in 8 cases (73%). It elicited the feeding artery and draining veins, the number of nidus and topography. We found 6 truncal AVM and 5 extratruncal including 4 limited. A first embolization was performed in 2 cases (18.2%). A one-stage surgery was performed in 7 cases and two times in 4 cases. The average hospital stay was 15 days [3 days-60 days]. The average healing time was 18 days [15 days-30 days]. Operative mortality as early mortality was zero. Late mortality was zero. The average follow-up time was 50.3 months [2 months-96 months]. In recent years, the multidisciplinary approach of tumors and vascular malformations has made important advances in the delineation of nosological frameworks and in the understanding of the natural history and structure of these complex lesions. This is why the treatment of these AVMs requires a multidisciplinary consultation exchange between vascular surgeons, plastic surgeons, interventional radiologists and anesthetists.
Radiologic Management of Vascular Malformations’ Interventional, Classification and Diagnosis
Journal of Health, Medicine and Nursing, 2017
This study aimed at analyzing the diverse group of congenital vascular malformations, with respect to their place within the broader classification of vascular anomalies and their pathologic, clinical, and radiologic diagnosis and management. And the study discuss some of the techniques, agents, and approaches used in the interventional treatment of this difficult group of lesions. The researchers are aware and acknowledge that there are several different techniques and agents that can be used to treat these lesions. The techniques and agents described in this article have been used for years by the experts with good results. The aim of this study is to share experience in the management of vascular malformations with these techniques at Jordanian hospitals, and to assess the patient satisfaction levels by the evaluation of the follow-up of patients with vascular malformations treated in the Interventional Radiology Unit from January 2016 to December 2016. Patients were classified a...
Scientific articles and newer editions of medical text books show significant misapprehension among authors and scientific fraternities over the correct nosology for diagnosing and reporting vascular anomalies/malformations. This perplex have led to indiscriminate, inappropriate, and interchangeable use of terminologies while describing these vascular lesions, often resulting in incorrect diagnosis, unwarranted investigations, and improper treatment. It is often impossible to determine clinically and histopathologically whether the vascular lesion is a malformation or a neoplasm, with more than 50% of the vascular anomalies being diagnosed and termed incorrectly as hemangioma. With the help of three case reports of simple vascular malformations, each afflicting the capillaries, veins and lymphatics, we attempt to guide the clinicians in adhering to the International Society for the Study of Vascular Anomalies (ISSVA) classification. We anticipate that this case report shall be the framework that helps clinicians and pathologists to avoid misdiagnosis and misreporting of vascular malformations.
Soft Tissue Angiomatosis: A Rare Cases Report
2018
Angiomatosis is a benign diffuse proliferation of blood vessels, concerning a wide body segment in a continuous pattern, involving multiple layers of tissue extending vertically or horizontally. These diffuse lesions make it difficult for clinicians to determine the limits of tumor-free tissue during resection, causing a high rate of angiomatous recurrence. We reportedcase of angiomatosisin 10yearold female patient. Patient complaint was a lump on the left thigh. On Physical examination found mass of the left femur region. Macroscopically showed a fairly large tumor mass, lesion with ill-defined, brownish patches and chewy consistency. On histopathology examination shown feature of randomly arranged blood vessel proliferation between the connective tissue of the dermisprofunda, subcutaneous fat, skeletal muscle tissue, and fatty tissue around the muscle. Blood vessels consist of arteries, veins and capillaries, some blood vessels appear to form clusters composed of thin-walled and t...

The diagnostic approach to vascular anomalies should include the distinction between vascular tumors (i.e. hemangiomas) and congential vascular malformations (CVMs). This step is based more on history and clinical examination rather than on instrumental evaluation. In children Duplex ultrasound and histology can be helpful to separate hypervasularized tumors from CVMs. Appropriate record of objective measures as size or flow volume is required in order to evaluate the progress of the pathology and/or to assess the results of adopted therapeutic interventions. The anatomic, pathological and hemodynamic characteristics, the secondary effects on the surrounding tissues and the systemic manifestations should be defined. Basic diagnostic tools are Duplex sonography followed by MRI or CT scanning. The definition of the vascular anomaly should be according to the Hamburg classification and should separate vascular tumors from vacular malformations followed by separation of high flow from l...

Congenital vascular malformations (CVM) are made of dysplastic vessels with no cellular proliferation. Low-or slow-flow malformations (LFM) consist predominantly of venous and/or lymphatic vessels. Correct terminology is necessary for differentiating vascular malformations from tumours such as haemangiomas, in order to prevent ineffective or even adverse therapy. The role of the radiologist in the management of patients is two-fold: making the diagnosis with the use of ultrasound and magnetic resonance imaging, and performing sclerotherapy, which is the treatment of choice. Prior to sclerotherapy, percutaneous phlebography is necessary to visualize the dynamic situation inside the lesion and the flow into the adjacent vascular system. The double-needle technique is a useful therapy option reducing the risk of embolisation of the sclerosing agent. Large lesions might need subsequent surgical treatment. A multidisciplinary approach is substantial for optimal patient management.
