A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the CAPILLARIES. The locations and size of the shunts determine the symptoms including HEADACHES; SEIZURES; STROKE; INTRACRANIAL HEMORRHAGES; mass effect; and vascular steal effect.
Congenital, inherited, or acquired abnormalities involving ARTERIES; VEINS; or venous sinuses in the BRAIN; SPINAL CORD; and MENINGES.
A vascular anomaly due to proliferation of BLOOD VESSELS that forms a tumor-like mass. The common types involve CAPILLARIES and VEINS. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE. (from Stedman, 27th ed, 2000)
An autosomal dominant vascular anomaly characterized by telangiectases of the skin and mucous membranes and by recurrent gastrointestinal bleeding. This disorder is caused by mutations of a gene (on chromosome 9q3) which encodes endoglin, a membrane glycoprotein that binds TRANSFORMING GROWTH FACTOR BETA.
A vascular anomaly composed of a collection of large, thin walled tortuous VEINS that can occur in any part of the central nervous system but lack intervening nervous tissue. Familial occurrence is common and has been associated with a number of genes mapped to 7q, 7p and 3q. Clinical features include SEIZURES; HEADACHE; STROKE; and progressive neurological deficit.
Congenital or acquired structural abnormalities of the lymphatic system (LYMPHOID TISSUE) including the lymph vessels.
The region of the face on either side, around the PAROTID GLAND.

A vascular malformation of developmental origin characterized pathologically by ectasia of superficial dermal capillaries, and clinically by persistent macular erythema. In the past, port wine stains have frequently been termed capillary hemangiomas, which they are not; unfortunately this confusing practice persists: HEMANGIOMA, CAPILLARY is neoplastic, a port-wine stain is non-neoplastic. Port-wine stains vary in color from fairly pale pink to deep red or purple and in size from a few millimeters to many centimeters in diameter. The face is the most frequently affected site and they are most often unilateral. (From Rook et al., Textbook of Dermatology, 5th ed, p483)
Veins draining the cerebrum.
Acquired degenerative dilation or expansion (ectasia) of normal BLOOD VESSELS, often associated with aging. They are isolated, tortuous, thin-walled vessels and sources of bleeding. They occur most often in mucosal capillaries of the GASTROINTESTINAL TRACT leading to GASTROINTESTINAL HEMORRHAGE and ANEMIA.
A congenital disorder that is characterized by a triad of capillary malformations (HEMANGIOMA), venous malformations (ARTERIOVENOUS FISTULA), and soft tissue or bony hypertrophy of the limb. This syndrome is caused by mutations in the VG5Q gene which encodes a strong angiogenesis stimulator.

A group of congenital malformations involving the brainstem, cerebellum, upper spinal cord, and surrounding bony structures. Type II is the most common, and features compression of the medulla and cerebellar tonsils into the upper cervical spinal canal and an associated MENINGOMYELOCELE. Type I features similar, but less severe malformations and is without an associated meningomyelocele. Type III has the features of type II with an additional herniation of the entire cerebellum through the bony defect involving the foramen magnum, forming an ENCEPHALOCELE. Type IV is a form a cerebellar hypoplasia. Clinical manifestations of types I-III include TORTICOLLIS; opisthotonus; HEADACHE; VERTIGO; VOCAL CORD PARALYSIS; APNEA; NYSTAGMUS, CONGENITAL; swallowing difficulties; and ATAXIA.

A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
A condition with multiple tumor-like lesions caused either by congenital or developmental malformations of BLOOD VESSELS, or reactive vascular proliferations, such as in bacillary angiomatosis. Angiomatosis is considered non-neoplastic.

Joseph Merrick, the so-called "elephant man", apparently suffered from Proteus syndrome and not NEUROFIBROMATOSIS, a disorder with similar characteristics.
The outermost of the three MENINGES, a fibrous membrane of connective tissue that covers the brain and the spinal cord.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
The vessels carrying blood away from the capillary beds.
A neoplasm derived from blood vessels, characterized by numerous prominent endothelial cells that occur singly, in aggregates, and as the lining of congeries of vascular tubes or channels. Hemangioendotheliomas are relatively rare and are of intermediate malignancy (between benign hemangiomas and conventional angiosarcomas). They affect men and women about equally and rarely develop in childhood. (From Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1866)
Usually a benign tumor, that commonly presents as a solitary blue nodule with spindled MELANOCYTES covered by smooth SKIN. Several variants have been identified, one variant being malignant. The blue color is caused by large, densely packed melanocytes deep in the DERMIS of the nevus. In CHILDREN, they usually occur on the BUTTOCKS and LUMBOSACRAL REGION and are referred to as cellular blue nevi. Malignant blue nevi are more commonly found on the SCALP.

Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)
A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).

CT and MRI of acquired portal venous system anomalies. (1/186)

In this educational presentation, we offer an overview of acquired anomalies of the portal venous system explored by biphasic helical CT and MRI. Portosystemic collateral vessels, cavernous transformation of the portal vein, intrahepatic vascular shunts, aneurysms of the portal venous system, thrombosis of the portal venous system, and gas in the portal venous system will be discussed. For liver surgery and interventional procedures it is necessary to have a correct mapping of normal anatomy, variants, and different pathologies involving the portal venous system.  (+info)

Common carotid agenesis and internal carotid stenting. (2/186)

Agenesis of common carotid artery is rare and no report of stenting procedures (carotid artery stenting) for associated stenosis of the internal carotid have been published. We report a case of internal carotid stenosis associated with this anomaly. A 73-year-old male with left internal carotid artery originating from the arch, with significant stenosis, was referred to us. Wallstent was deployed with success. Carotid artery stenting should be reserved to uncomplicated arch anatomy and plaques with low fragmentation risk.  (+info)

Portal cavernomatous transformation leading to variceal hemorrhage in Sturge-Webber syndrome. A rare, but possible association. (3/186)

Sturge-Weber syndrome is a rare disorder consisting of a port-wine nevus in the distribution of the ophthalmic branch of the trigeminal nerve and central nervous system malformations. Facial cutaneous vascular malformation, seizures, and glaucoma are among the most common symptoms and signs. The syndrome results from malformation of the cerebral vasculature located within the pia mater, most commonly over the occipital region. These malformations led to venous hypertension and subsequent hypoperfusion on the underlying cortex, causing chronic cerebral ischemia, atrophy, calcification and neurological deterioration. We describe 18-years-old young girl hospitalized for upper digestive hemorrhage that revealed a cavernomatous transformation of portal vein. At the same time, she presents extensive congenital, bilateral port wine stains on the face, epilepsy and glaucoma of the right eye. Computer tomography showed intracranial vascular abnormalities with calcifications, particularly in the right occipital lobe. The clinical presentation and imagistic assessment confirmed the diagnosis of Sturge-Weber syndrome associated with upper non-cirrhotic portal hypertension generated by a malformation of portal vein. CONCLUSIONS: Upper digestive hemorrhage is a quite rare eventuality in the Sturge-Webber syndrome. Moreover, portal tract malformations with cavernomatous transformation are exceptionally cited in the literature. Despite this rare association, abdominal investigation, as well as computed cranial tomography should be performed in all cases of children that present a facial cutaneous vascular malformation.  (+info)

A systematic approach to the use of the multiplanar display in evaluation of abnormal vascular connections to the fetal heart using 4-dimensional ultrasonography. (4/186)

OBJECTIVE: The multiplanar display is a modality that allows the simultaneous visualization of 3 orthogonal planes from volume data sets obtained with 3- and 4-dimensional ultrasonography. Simultaneous display of standard views used in fetal echocardiography and their orthogonal planes may provide novel ultrasonographic views for examination of the fetal heart and its vascular connections. This study was designed to determine the clinical utility of the multiplanar display in the examination of abnormal vascular connections to the fetal heart. METHODS: We reviewed 4-dimensional volume data sets, acquired with the spatiotemporal image correlation technique, from patients with abnormal vascular connections to the fetal heart. Multiplanar views of the fetal heart were used to simultaneously display standard planes used in fetal echocardiography and their corresponding orthogonal planes. RESULTS: This study included 4 volume data sets from fetuses with confirmed abnormal vascular connections to the heart, including: (1) an interrupted inferior vena cava with azygos or hemiazygos vein continuation; (2) a persistent left superior vena cava draining into a dilated coronary sinus; and (3) a dilated superior vena cava associated with a thoracic lymphangioma. Simultaneous visualization of orthogonal planes displaying abnormal vascular connections to the fetal heart facilitated identification of the abnormal vessels and their spatial relationships with other vascular structures. CONCLUSIONS: Multiplanar imaging can be used to assess abnormal vascular connections to the fetal heart and may provide novel ultrasonographic planes for fetal echocardiography using 3- and 4-dimensional ultrasonography.  (+info)

Unilateral absence of the pulmonary artery incidentally found after an episode of hemoptysis. (5/186)

A 29-year-old woman was admitted to our hospital because of hemoptysis and dyspnea. A chest radiographic study revealed an enlargement of the right lung hilum, and the left pulmonary artery could not be clearly visualized on contrast-enhanced CT scan. Both perfusion scintigraphy and pulmonary angiography confirmed the absence of the left pulmonary artery, and agenesis of the right upper pulmonary artery. Her clinical status has been stable for the previous two years of follow-up, even though she required long-term oxygen therapy. This is a rare case of a young woman with the unilateral absence of the left pulmonary artery incidentally found after an episode of hemoptysis.  (+info)

Effectiveness of low flow vascular lesions sclerosis with monoethanolamine: report of six cases. (6/186)

Vascular malformations or even hemangiomas need therapeutic intervention if they start to cause clinical symptoms or personal discomfort. Different therapeutic modalities, including cryotherapy, corticosteroids, laser therapy, sclerotherapy, surgery, and/or embolization, can be performed successfully. Sclerotherapy with monoethanolamine is a relatively simple and effective method to treat low flow vascular lesions. We presented a report of six cases of vascular malformations treated with monoethanolamine. There were 3 male and 3 female patients, with an age range of 20 to 68 years. The patients were submitted to applications according to clinical response and/or tolerability. In all cases, low-flow vascular lesions were recorded and submitted to infiltration with 2.5% monoethanolamine, directly into the lesions. The volume applied was approximately the middle of affected area. Vascular lesions were characterized as low-flow due to absence of arterial pulsation and flat consistence. The sclerosis with 2.5% monoethanolamine resulted in complete or partial involution, without severe complications.  (+info)

Angiogenesis and vascular malformations: antiangiogenic drugs for treatment of gastrointestinal bleeding. (7/186)

Treatment of gastrointestinal bleeding in patients with angiodysplasias and Osler's disease (hereditary hemorrhagic teleangiectasia) is clinically challenging. Frequently, vascular malformations occur as multiple disseminated lesions, making local treatment an unfavorable choice or impossible. After local therapy, lesions often recur at other sites of the intestine. However, as there are few therapeutic alternatives, repeated endoscopic coagulations or surgical resections are still performed to prevent recurrent bleeding. Hormonal therapy has been employed for more than 50 years but has recently been shown to be ineffective. Therefore, new therapeutic strategies are required. Understanding of the pathophysiology of angiogenesis and vascular malformations has recently substantially increased. Currently, multiple inhibitors of angiogenesis are under development for treatment of malignant diseases. Experimental and clinical data suggest that antiangiogenic substances, which were originally developed for treatment of malignant diseases, may also represent long-awaited specific drugs for the treatment of vascular malformations. However, antiangiogenics display significantly different actions and side-effects. Although antiangiogenics like thalidomide seem to inhibit gastrointestinal bleeding, other substances like bevacizumab can cause mucosal bleeding. Therefore differential and cautious evaluation of this therapeutic strategy is necessary.  (+info)

A Japanese family of typical Loeys-Dietz syndrome with a TGFBR2 mutation. (8/186)

This report describes a Japanese family with vessel and craniofacial abnormalities. Although the clinical findings of the patient's father fulfilled the diagnostic criteria for Marfan syndrome, arterial tortuosity, aneurysms, hypertelorism and a bifid uvula were noted in both the patient and his father. These findings were compatible with the clinical manifestations that were previously reported in Loeys-Dietz syndrome. A molecular genetic analysis demonstrated a heterozygous missense mutation of the transforming growth factor-beta receptor II gene in both the patient and his father, which thus caused Loeys-Dietz syndrome. This is the first Japanese family case report of typical Loeys-Dietz syndrome.  (+info)

Vascular malformations are congenital anomalies that can affect each part of the vasculature. Combined forms are common and they are often part of complex syndromes. Most malformations are diagnosed during infancy, but some get obvious only later in life. The field of vascular malformations is emerging with recently described new entities and treatments. Still, misdiagnosis is common in this field, leading to nosologic confusion and wrong treatment. Clinical evaluation and imaging are the gold standard for diagnostic confirmation. Sclerotherapy and embolization are the main treatment techniques but are also used preoperatively to reduce blood loss and shrink the lesion if surgery is planned. Despite new treatment options, especially if extensive in size or involving vulnerable structures, vascular malformations are still considered chronic diseases and cause significant morbidity. Common understanding and agreement on terminology and a multidisciplinary approach are the basis of successful ...
We can see the parallels --the tossing aside of Dr. Putnams research after a lack of a cure and the discontent with Dr. Zambonis CCSVI research and the lack of an immediate cure. I worry that the immunological side of MS is given all of the research money and time, while the vascular connection remains underexplored and underfunded. I worry that the focus on a cure is put before the understanding of MS pathogenesis. How can we cure what we do not understand? It bothers me that there is not more curiosity in the neurological world regarding truncular venous malformations and hypo perfusion. As regular people, we can see the direct connection from Dr. Putnams studies on veins in dogs, to Dr. Zambonis discovery of intraluminal malformations in jugular veins, and the hemodynamic changes in blood flow in people with MS. Why is there not more curiosity in MS specialists? Where are the Tracy J. Putnams? ...
Congenital hemangioma can be distinguished from infantile hemangioma because it is fully developed at birth. It forms during prenatal life and has reached its maximal size at birth. Congenital hemangioma can even be diagnosed in utero by prenatal ultrasound. Unlike IH, CH is more common in the extremities, has an equal sex distribution, and is solitary, with an average diameter of 5 cm. It commonly presents in the head and neck and in the lower extremities. Congenital hemangioma are divided into 2 subgroups: the rapidly involuting congenital hemangiomas (RICHs) and the non-involuting congenital hemangiomas(NICHs). The rapidly involuting congenital hemangioma, RICH, presents at birth as a solitary raised tumor with a central depression, scar, or ulceration surrounded by a rim of pallor. It is noted for its involution, which typically begins several weeks after birth and is completed no later than 14 months of age.[9] After regression RICH may cause a residual deformity, such as atrophic skin and ...
Grey-scale and Doppler ultrasound (US) are alternative modalities to diagnose soft-tissue vascular anomalies [16]. However, US has only a limited ability to display the full extent of large lesions and to demonstrate an intra-osseous component [17,18]. Some MRI techniques have been used for classification of peripheral vascular lesions [18,19,20]. Time-of-flight MR angiography can show feeding arteries with high-flow; however, this modality has a limitation regarding smaller vessels [19]. A previous study by van Rijswijk et al. [20] has demonstrated that with the use of the dynamic contrast-enhancement gradient-echo technique, venous malformations were distinguished from non-venous malformations with high specificity. Another study has demonstrated that time-resolved MR projection angiography was useful for the separation of high- and low-flow vascular malformations [18]. Although direct puncture venography is useful for the diagnosis of VMs and also for confirming lymphatic fluid leaks to ...
Patients with vascular anomalies (VA) have a spectrum of diseases that can be broadly classified into vascular tumors and malformations. Complicated vascular anomalies can cause disfigurement, chronic pain, and organ dysfunction with significant morbidity and mortality. Despite the severity of potential complications, we lack uniform guidelines for the treatment and response to treatment of children and young adults with these diseases. There are pre-clinical and clinical data supporting the essential regulatory function of the PI3K/Akt/mTOR pathway in vascular growth and organization, and suggest a therapeutic target for patients with complicated vascular anomalies. The overall goal of this trial is to objectively determine the effectiveness and safety of the mTOR inhibitor Rapamycin* in the treatment of children and young adults diagnosed with complicated vascular anomalies. We propose a Phase 2 trial with the diagnostic, therapeutic and response criteria experimentally determined in this ...
Objective: The aim of this study was to analyze a single institutions experience of solitary venous malformation (VM) in the midcheek region. Study design: From 2002 to 2009, a total of 10 consecutive patients with solitary venous malformation in the midcheek region were retrospectively analyzed. Clinical records were reviewed for patient demographic data, presenting symptoms and signs, imaging modalities used, histologic and immunohistochemical results, surgical data, and clinical outcomes. Results: The sample consisted of 5 males and 5 females with a mean age of 42.8 years. The course of disease ranged from 0.5 to 144.0 months with a mean time of 64.9 months. The mean size of the masses was 1.7 × 1.5 cm (range 1.0 × 0.8 cm to 2.5 × 2.5 cm). Investigations included Doppler ultrasonography (US) and computed tomography (CT) scanning. Surgical excision using various surgical approaches was performed in all patients. Postoperative pathologic examination confirmed the diagnosis of VM. The mean ...
The relationship of the vascular system in MS is being explored, and dealt with in a sideways manner by neurologists. I do not expect we will ever hear that CCSVI is valid science from neurologists--they will attempt to rename it, requantify slowed venous return and hypoperfusion, and make it their own. They will call Dr. Zambonis discovery of CCSVI junk science- while they are working on patenting drugs to address blood flow in pwMS. This is because neurologists work with pharma and write prescriptions. They do not deal with the mechanistics of the brains circulation or with the venous malformations Dr. Zamboni has discovered. They are not phlebologists or vascular surgeons. For MS specialists, this discovery of hemodynamic alterations goes beyond their practical expertise. ...
Vascular malformations (VM) are complex lesions present in various anatomical locations with a variety of clinical manifestations. Time-resolved MRA combined with parallel imaging and echo sharing schemes offer a reasonable alternative to more invasive diagnostic methods such as digital subtraction angiography (DSA) in evaluation of VMs. MRI is becoming the imaging modality of choice in assessing morphological issues regarding VMs. Time-resolved MRA can play an important role in characterizing these lesions and can influence therapeutic decision-making. [...] ...

Vascular malformations of the limbs are rare congenital anomalies with only 20% of these cases reported to have associated osseous involvement [1]. According to the international society for the study of vascular anomalies (ISSVA), vascular anomalies are divided into vascular tumours and vascular malformations (VM). Vascular tumours are further subdivided into benign, borderline and malignant tumours, while VM are further classified into 5 types: the 1st is the simple type (one type of malformation in the lesion as capillary or venous or lymphatic or arterial), AVM and AVF are also included in this group, the 2nd type of VM is the combined type (two or more malformations in the same lesion as CVM, CAVM, CLAVM), the 3rd type of VM are malformations of major named vessels, also called truncal malformations, and these are further classified according to the type of the involved vessels (lymphatics, veins, arteries ) or classified according to the nature of the defect as abnormalities of origin, ...
Matrix metalloproteinases (MMPs) are increased in rat and mouse models of hypoxic hypoperfusion and have been associated with OLG death. However, whether the MMPs act on myelin or OLGs remains unresolved. We hypothesized that delayed expression of MMPs caused OLG death and myelin breakdown. To test the hypothesis, adult mice underwent hypoxic hypoperfusion with transient bilateral occlusion of the carotid arteries. After 3 days of reperfusion, ischemic white matter had increased reactivity of astrocytes and microglia, MMP-2 localization in astrocytes, and increased protein expression and activity of MMP-2. In addition, there was a significant loss of myelin basic protein (MBP) by Western blot and caspase-3- mediated OLG death. Treatment with the broad-spectrum MMP inhibitor, BB-94, significantly decreased astrocyte reactivity and MMP-2 activity. More importantly, it reduced MBP breakdown. However, MMP inhibition had no effect on OLG loss. Our results implicate MMPs released by reactive ...
I became interested in multiple sclerosis (MS) research when my husband Jeff was diagnosed with MS in 2007. I noted a connection of Jeffs disease process to his circulation and blood, and by accessing medical journals on the internet and stacks of books at my local library, I put together research to address this. I sent my theory and research, called the Endothelial Health Program, to universities, and began a correspondence with vascular specialists at Stanford University. Jeff was the first American treated for CCSVI, and he is now eight years past his venoplasty, with no further MS progression, healing of his gray matter, and relief of many symptoms. Hes still jogging, working full time as a composer and conductor, and traveling the globe ...
TY - JOUR. T1 - Anatomical repair of a persistent left superior vena cava into the left atrium. AU - Ugaki, Shinya. AU - Kasahara, Shingo. AU - Fujii, Yasuhiro. AU - Sano, Shunji. PY - 2010/8. Y1 - 2010/8. N2 - The anatomy of a persistent left superior vena cava (SVC) to the left atrium (LA) without the innominate vein can make it challenging to complete intracardiac repair. We reviewed our five cases of the direct end-to-side anastomosis of SVCs to facilitate anatomical repair of SVC-right atrial connection for biventricular repair. Diagnoses were two partial atrioventricular septal defect with left isomerism, one complete atrioventricular septal defect (CAVSD) with left isomerism, one CAVSD without isomerism and one atrioventricular discordance and double outlet right ventricle with right isomerism. Mean age at the operation was 20±23 months (4-58 months) and body weight was 7.8±3.4 kg (4.8-12.7 kg). After completion of intracardiac repair, the SVC to LA was divided and end-to-side ...
The persistence of left superior vena cava (PLSVC) is the most common congenital anomaly of the venous return system to the heart. Because of the increasing number of patients referred for cardiac resynchronization therapy (CRT) devices implantations, it is expected to encounter this venous anatomic variation. Left ventricular lead placement at an appropriate site is an integral and technically challenging part of successful CRT. In case of cardiac abnormalities could be difficult to achieve an optimal cardiac rhythm management devices implantation. Previous reports in patients with PLSVC highlighted the challenges to achieve an optimal cardiac rhythm device implantation. Recently, a new quadripolar active fixation left ventricular lead is available for CRT device implantation. Hereby we report a case of a device upgrading from dual-chamber pacemaker to CRT with defibrillator backup using the active fixation left ventricular quadripolar lead in a patient with PLSVC and right superior vena cava atresia.
Persistent left superior vena cava (PLSVC) and horseshoe kidney (HSK) are common congenital abnormalities; however presence of both in the same person is extremely rare. A patient with hepatitis C cirrhosis awaiting transplant presented with worsening liver dysfunction, diagnosed with acute renal failure secondary to hepatorenal syndrome, and required X-ray fluoroscopy guided tunneled venous catheter placement for hemodialysis. Review of imaging studies demonstrated coexistence of PLSVC and HSK. PLSVC in adulthood is usually incidental with the most common drainage pattern being without physiologic dysfunction. Isolated horseshoe kidney is still the most common of renal fusion anomalies; however etiology of coexistent PLSVC remains unknown.
CONGENITAL anomalies of the great veins of the neck are relatively infrequent. Persistent left superior vena cava (PLSVC) is an embryologic remnant of the left superior cardinal vein seen in 0.1 to 0.3% of healthy adults.1 PLSVC runs between the left pulmonary veins and the left atrial appendage enlarging the coronary sinus as it enters the atrium. When present, it can affect placement of central catheters, pacemakers, and cardiopulmonary bypass. It is important to be aware of this variation and to recognize it in imaging studies ...
INTRODUCTION: Floating thrombus in an aberrant right subclavian artery is a rare cause of peripheral arterial embolic events. CASE REPORT: We report a 45-year-old woman who presented with an ischemia of the right superior limb from embolic event. The diagnosis of mobile thrombus in an aberrant right subclavian artery was obtained with transoesophageal echocardiography and computed tomography. After three weeks of oral anticoagulant therapy, there was no significant resolution of the thrombus, and a surgical treatment was performed to prevent further embolization. The surgical procedure consisted of thrombectomy and reimplantation of the aberrant right subclavian artery to the right carotid artery. Postoperative recovery was uneventful. CONCLUSION: This case report illustrates that transoesophageal echography and computed tomography are useful to detect mobile thrombus of the thoracic aorta and is warranted in any embolic event in young patients.
Aberrant subclavian artery is a rare vascular anomaly that is present from birth. It usually causes no symptoms and is often discovered as an incidental finding (such as through a barium swallow or echocardiogram). Occasionally the anomaly causes swallowing difficulty (dysphagia lusoria). Swallowing symptoms in children may present as feeding difficulty and/or recurrent respiratory tract infection. When aberrant subclavian artery causes no symptoms, treatment is not needed. If the anomaly is causing significant symptoms, treatment may involve surgery. Children with symptomatic aberrant subclavian artery should be carefully evaluated for additional vascular and heart anomalies ...
Background: Scimitar syndrome is a rare and complex congenital defect that often involves hypoplasia of the right lung, partial anomalous pulmonary venous connection of the right lung draining into the inferior vena cava, and a systemic collateral artery from the descending aorta supplying the right lower lobe (lobar sequestration). Our case was a male newborn with scimitar syndrome associated with an absent right pulmonary artery, imperforated anus, and coarctation of the aorta. Hemodinamically, the patient was asymptomatic and diagnosed accidentally. This combination has not been reported before. The pathological process of the scimitar syndrome is unclear. However, it appears to originate from a basic developmental disorder of the complete pulmonary bud early in embryogenesis. This rare syndrome with different presentations can occur alone or in combination with cardiac and /or non-cardiac anomalies.

In each case, an insidious clinical course, combined with the pathognomonic finding of radiating trabeculae on ...
Of a total of 213 patients with spinal vascular malformations, 27 (12.7%) had vascular malformations in the cervical spine. The mean patient age was 46.1 ± 21.9 years and 16 (59.3%) were male. The most common presentations were lower-extremity weakness (13 patients, 48.1%), tetraparesis (8 patients, 29.6%), and lower-extremity sensory dysfunction (7 patients, 25.9%). Nine patients (33.3%) presented with hemorrhage. Fifteen patients (55.6%) had modified Rankin Scale scores of 0-2 at the time of diagnosis. Regarding angioarchitectural characteristics, 8 patients (29.6%) had intramedullary arteriovenous malformations (AVMs), 5 (18.5%) had epidural arteriovenous fistulas (AVFs), 4 (14.8%) had paraspinal fistulas, 4 (14.8%) had mixed epidural/intradural fistulas, 3 (11.1%) had perimedullary AVMs, 2 (7.4%) had dural fistulas, and 1 patient (3.7%) had a perimedullary AVF. ...
A two-year-old Border Collie presented with a three-month history of regurgitation. Investigation with plain radiography, digital fluoroscopy, endoscopy and CT angiography (CTA) confirmed the presence of an aberrant right subclavian artery causing dorsal oesophageal compression. In this report, CTA was used to depict the anatomy of an aberrant right subclavian vessel and to highlight the importance of this imaging modality to identify the structures involved in a vascular ring. This report also identifies a patient with a congenital vascular ring anomaly presenting with adult-onset regurgitation, which has been successfully managed with medical treatment. ...
Shivaram: Historically, there hasnt been a great way to treat them. In interventional radiology (IR) we would use sclerotherapy, which involved injecting the venous malformation with medications to scar the veins down, but this often required multiple sessions with variable results. Surgical removal alone was problematic because malformations bleed a lot and its hard to get around them.. This new hybrid procedure has revolutionized the way they are managed. While the patient is under anesthesia, we inject glue into the channels of the venous malformation, which we can see with ultrasound. The patient then goes to the operating room (OR) where the surgeon can see the malformation (due to the hardened glue) and surgically remove it. There is much less bleeding since the vascular channels of the malformation are blocked. We have performed more than 40 of these procedures over the last year and our patients have done amazingly well.. ...
A venous malformation (VM) is a place in the body where veins havent developed in the usual way. Veins in a VM tend to be larger and more tangled than normal veins. A venous (VEE-nis) malformation close to the skin usually looks like a maroon, blue, or purple spot.. Kids who have VMs are born with them. A VM might not be visible until later when it has gotten bigger or its veins have stretched. Venous malformations that are deep in the muscles or body might not be found until a child has pain or swelling. A VM grows as a child grows, and also might be more noticeable in response to injury or partial removal.. ...

Erondu-Cymet Syndrome, 978-620-0-83887-2, Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Erondu-Cymet syndrome is a syndrome caused by a translocation on the . The genetic for people with this condition is 46, XY, inv(21)(q11.2q22.1). Findings in these patients include: hypotension, hypoxemia, seizures, and impairment of cognitive ability. Patients with this condition may have persistent left superior vena cava that drains into the left atrium, as well as pulmonary arterio-venous malformations. Erondu-Cymet Syndrome was discovered in 2006 by Ugochi Erondu and . In 2000, researchers working on the announced that they had determined the sequence of that make up this chromosome. Chromosome 21 was the second human chromosome to be fully sequenced.
The field of vascular anomalies has grown rapidly in last 25 years. Molecular genetics has led to discovery of genes that cause vascular anomalies. Interventional radiology has become a major contributor to accurate diagnosis and management of previously untreatable disorders. New pharmacologic therapies are under investigation and surgical protocols have been established.

Aberrant right subclavian artery (ARSA) or arteria lusoria is one of the most common congenital aortic arch anomaly with prevalence ranging from 1-2%. However, it is mostly asymptomatic and consequently often found sporadically during various diagnostic procedures with prevalence of 0.45% during coronary angiography.
Thus , a lot of IVF specialists , before doing an IVF cycle , will routinely refer their patient to a gynecologist , and will ask them to do a hysteroscopy and/or laparoscopy for them. The purported reason for this is to optimize the endometrial cavity , in order to enhance embryo implantation. This is often done by doing a procedure called metroplasty, which is supposed to increase the capacity of the uterine cavity. This is a procedure which seems to be performed only in India ; and there is no evidence that it actually helps fertility rates at all. After all , the shape of the endometrial cavity has very little bearing on the fertility potential of the woman ; and there are a lot of normal anatomic variants within the fertile population as well. However, when an infertility specialist sees these normal anatomic variants in an infertile women, they tend to over treat them, and refer them to endoscopic surgeons to do procedures which not only are not helpful , but can actually be harmful . They ...

Conventional radiography may show a soft-tissue mass and calcifications. Ultrasound features are nonspecific with an ill-defined, variably echogenic lesion that may contain foci of calcification [2], but Doppler ultrasound plays a key role for diagnosis because it demonstrates its high vascularised nature. Nevertheless, MR imaging of the affected skin region constitutes the best diagnostic imaging method. T1-weighted imaging reveals typical ill-defined hypointense soft-tissue thickening involving multiple planes, and on T2-weighted imaging it demonstrates heterogeneous hyperintense masses with internal dark signal intensity channels, due to vascular flow voids. The post-contrast sequences reveal diffuse and heterogeneous enhancement [1-4]. Although whole-body MR is not necessary for diagnosis, it may be considered during diagnostic work-up of patients with clinically suspected vascular malformations, to identify multiple lesions and their distribution in diffuse vascular malformations, such as ...
Doctor Orange characterized CMTC as neither tumor nor vascular malformation, but something in between. Furthermore, CMTC may diminish somewhat over time, but does not disappear completely. The most commonly observed abnormality in CMTC is corporal asymmetry. The most important conclusion is that CMTC is a mixed vascular malformation.. The presentation can be found on our website in the members section.. Propranolol, an old beta-blocker, was discovered by chance as an option for the treatment of hemangiomas. However, there are many uncertainties regarding the safety and monitoring of this therapy. The most serious side effects are bradycardia and hypotension. Infants with large hemangiomas or miliary hemangiomatosis are at risk of cardiac output problems. Also, propranolol may mask hypoglycemia in these patients, which can lead to severe neurological side effects. Generally in the Netherlands and elsewhere there are various therapies - protocols. In Rotterdam we remain conservative and ...

They are going to try a targeted patch at T7. It seems that surgery is too risky, where the leak is at T7 is surrounded by my venous malformation and if they were to operate, bleeding very risky tend to lose litres of blood very quickly, so best avoided.

PURPOSE: We aimed to evaluate the safety and effectiveness of cryoablation in the treatment of low-flow malformations, specifically venous malformation (VM) and fibroadipose vascular anomaly (FAVA). METHODS: We conducted a retrospective review of 11 consecutive patients with low-flow malformations (14 lesions; 9 VM, 5 FAVA), median lesion volume 10.8 cm3, (range, 1.8-55.6 cm3) with a median age of 19 years (range, 10-50 years) who underwent cryoablation to achieve symptomatic control. Average follow-up was at a median of 207 days postprocedure (range, 120-886 days). Indications for treatment included focal pain and swelling. Technical success was achieved if the cryoablation ice ball covered the region of the malformation that corresponded to the patients symptoms. Clinical success was considered complete if all symptoms resolved and partial if some symptoms persisted but did not necessitate further treatment. RESULTS: The technical success rate was 100%. At 1-month follow-up, 13 of 14 lesions ...
