Fibroadipose vascular anomaly (FAVA) is a rare, complex mesenchymal malformation combining fibrofatty replacement of the affected muscles and slow-flow vascular malformation. The condition is characterized by localized swelling, severe pain, phlebectasia, and contracture of the affected limb. Treatment paradigms are not well established for this rare, recently recognized condition. We report two cases of FAVA in which treatment with sirolimus produced rapid, dramatic improvement in pain and quality of life.

Life-threatening cardiovascular anomalies require surgery for structural repair with cardiovascular patches. The biomaterial patch, derived from Bombyx mori silk fibroin (SF), is used as an alternative material due to its excellent tissue affinity and biocompatibility. However, SF lacks the elastomeric characteristics required for a cardiovascular patch. In order to overcome this shortcoming, we combined the thermoplastic polyurethane, Pellethane® (PU) with SF to develop an elastic biocompatible patch. Therefore, the purpose of this study was to investigate the feasibility of the blended SF/PU patch in a vascular model...

Lymphedema is a localized form of tissue swelling resulting from excessive retention of lymphatic fluid in the interstitial compartment and caused by impaired lymphatic drainage. Lymphedema is classified as primary or secondary. Primary lymphedema is caused by developmental lymphatic vascular anomalies. Secondary lymphedema is acquired and arises as a result of an underlying systemic disease, trauma, or surgery. We performed PubMed and Google Scholar searches of the English-language literature (1966-2017) using the terms lymphedema, cancer-related lymphedema, and lymphatic complications...

Surgery for the Cranio-vertebral (CV) junction anomalies using top loading subocciput (C0)/C1-C2 screws is difficult and requires high level of skill and expertise. This is because of complex abnormal anatomy in that region and other issues including the instrumentation. Thorough knowledge of the 3D anatomy of the Craniovertebral junction of the patient is essential for favourable outcome. The customised 3D printed model of CV junction region of the patient can be used for studying the anatomy and relationship of vertebral artery to the C1-C2 joint before the actual surgery...

AIM: There is controversy regarding the diagnosis and classification of vascular anomalies (VA). As torso and extremities are the second most common body part for presentation of VAs, musculoskeletal (MSK) radiologists play a central role in VA classification. The purpose of this study was to evaluate the awareness and clinical use of the International Society for the Study of Vascular Anomalies (ISSVA) classification by MSK radiologists. MATERIALS AND METHODS: A Web-based survey was designed and electronically sent to Society of Skeletal Radiology (SSR) members, with 3 questions on demographics and 7 questions on ISSVA classification use and knowledge...

Developmental venous anomalies are cerebral vascular malformations that present normal venous drainage of cerebral tissue. With increased and accessible usage of modern diagnostic tools, they are now one of the most commonly diagnosed cerebral vascular malformations. Although developmental venous anomalies are considered to be benign lesions, association with arteriovenous malformation renders malignant potential to this combined pathology. In the case presented, these malformations were clinically silent and diagnosed accidentally, so they were not treated either with surgery, endovascular surgery or radiosurgery, considering the possible complications such as venous infarction of the brain, and because there was no obvious neurologic deficit related to this pathology...

Individuals with chronic illnesses must manage long-term uncertainty as they cope with the ways the illness influences their lives. In the context of pediatric illnesses, parents must manage uncertainty during the diagnosis and treatment of their child's illness. It is common for children with complex chronic illnesses to see multiple specialists for the treatment of their condition. While previous research has explored parents' uncertainty during a child's diagnosis and during end-of-life care, less is known about these experiences when the child is referred to a team of specialists for treatment...

Ovotesticular disorder of sexual development (OT-DSD), previously true hermaphroditism, is a condition in which one or both gonads contain testicular and ovarian tissue. A 23-year-old OT-DSD male patient presented with continuous pain in his right testicle which had been previously intermittent over the past five days. The patient had a prior history of left ovotestis removal with prosthesis placement, a right undescended testicle with aberrant anatomy, and hypospadias repair, all of which were corrected shortly after birth...

Right-sided ligamentum teres (RSLT) is a rare congenital anomaly often accompanied by variation of the hepatic vasculature. We herein report a surgical case of a hilar cholangiocarcinoma with RSLT in whom preoperative hepatectomy simulation proved useful for understanding the anatomical structure of the liver. A 78-year-old male with obstructive jaundice was referred to our department for further examination. The patient was suspected of having a hilar cholangiocarcinoma originating from the left hepatic bile duct by contrast-enhanced computed tomography (CT), and CT also showed right umbilical portion (RUP)...

Although the use of vasopressin has become common place in pediatric patients with vasodilatory shock after cardiac surgery, its efficacy and hemodynamic effects have not been systematically documented. Furthermore, previous studies were mainly limited patients with left heart anomalies. To date, the use of vasopressin in patients with right heart anomalies hasn't yet been reported. To clarify the hemodynamic effects of vasopressin on pediatric patients with vasodilatory shock after cardiopulmonary bypass, 70 consecutive patients, most of whom with right heart anomalies were retrospectively analyzed in Fuwai Hospital from October 2013 to September 2015...

A 28-year-old man without a significant medical history visited our hospital complaining of a headache. Computed tomography (CT) demonstrated thick, calcified vertebral artery (VA) and basilar artery (BA), despite the patient being young. Magnetic resonance angiography demonstrated the absence of the left internal carotid artery (ICA). The right ICA, the bilateral VA, and the BA were well developed and dolichoectatic. CT revealed the absence of the carotid canal on the left side. The condition was diagnosed as congenital agenesis of the left ICA with dolichoectatic changes in 3 other arteries...

Vascular anomalies are classified as tumors and malformations depending on their clinical characteristics, pathological diagnosis and recent genomic information. Diagnosis can still be challenging because of the heterogeneity of clinical presentation. Thus, the best care is provided by an interdisciplinary team of specialists. An updated classification system has helped provide more consistent terminology with the addition of new diagnoses and genomic discovery. Historically, treatment of vascular anomalies was primarily surgical and or interventional with limited medical therapies...

BACKGROUND: Anomalies of vertebral arteries are rare, and usually detected incidentally. However, very rarely, they can manifest clinical symptoms. We describe such a symptomatic case of high cervical spinal cord compression associated with persistent C2 segmental arteries. CASE DESCRIPTION: A 67-year-old man presented with a 5-year history of worsening left-sided weakness and gait disturbance. Magnetic resonance imaging, 3D-computed tomography and digital subtraction angiography revealed anomalous courses of vertebral arteries, compressing the cervical spinal cord at C1 level from both sides...

Tinnitus is the perception of sound in the absence of an external source. It is a common symptom that can be related to hearing loss and other benign causes. However, tinnitus may be disabling and can be the only symptom in a patient with a central nervous system process disorder. History and physical examination are crucial first steps to determine the need for imaging. CT and MRI are useful in the setting of pulsatile tinnitus to evaluate for an underlying vascular anomaly or abnormality. If there is concomitant asymmetric hearing loss, neurologic deficit, or head trauma, imaging should be guided by those respective ACR Appropriateness Criteria(®) documents, rather than the presence of tinnitus...

A 77-year-old male patient presented with dysphonia. Endoscopic examination demonstrated a distortion of the posterior pharyngeal wall, which was pulsatile. The axial CT showed left internal carotid artery in a retropharyngeal location. An anomalous course of the carotid artery in the retropharyngeal space is an unusual finding that poses a risk of vascular injury during pharyngeal surgery and intubation. Such an anomaly may be congenital (incomplete descent of the third aortic arch) and may be more pronounced in older patients secondary to atherosclerosis and hypertension as occurred in our case noted here...

BACKGROUND: Antiepileptic treatment strategy plays an important role in the management of intracranial vascular malformations. The intracranial vascular malformations can be divided into cavernous hemangiomas, arteriovenous malformations, developmental venous anomalies and capillary telangiectasias. Seizures and hemorrhage are among their most common clinical manifestations. OBJECTIVE: The aim of this article is to review the current literature on the antiepileptic treatment in the setting of intracranial vascular malformations and offer an updated view on when antiepileptic drug treatment should be employed for each type of vascular malformation...

Pancreatic dorsal agenesis (PDA) is a rare congenital anomaly, usually asymptomatic, that can present with abdominal pain, pancreatitis, diabetes mellitus and jaundice. Pancreatic tumours in PDA background are extremely rare, and when they occur are mainly pancreatic ductal adenocarcinoma. We present a case of a 48-year-old female patient with incidental detection of a 26×20 mm nodular lesion of the cephalic pancreas on ultrasound. Surgery was performed and gross examination revealed PDA with a tumour developed around the Wirsung duct...
