Short posterior ciliary arteries (sPCA) provide the major blood supply to the optic nerve head. Emerging evidence has linked structural and functional anomalies of sPCA to the pathogenesis of several ocular disorders that cause varying degrees of visual loss, particularly anterior ischaemic optic neuropathy and glaucoma. Although the functional relevance of this vascular bed is well-recognized, the proteome of sPCA remains uncharacterized. Since the porcine ocular system closely resembles that of the human's and is increasingly employed in translational ophthalmic research, this study characterized the proteome of porcine sPCA employing the mass spectrometry-based proteomics strategy...

BACKGROUND: Vascular anomalies accompanied with the diploic veins are rare. Among them, sinus pericranii, which is characterized by abnormal connections between intra- and extracranial venous systems, is relatively common. Besides sinus pericranii, a few cases of subepicranial varix with connections to diploic veins have been reported, but these varices had no connections to intracranial venous sinuses. Herein, we present a rare case of an expanding venous sac in the diploe which communicated with the intracranial sinus but not with the extracranial venous systems...

We report the imaging findings of an uncommon coronary vascular termination anomaly, with fistula to the pulmonary artery. This 70 year old female patient presented unstable angina, showing a coronary artery fistula depicted in coronary angiogram from the left coronary to the pulmonary artery, with no significant atherosclerotic pathology. Due to development of ventricular tachycardia in stress echocardiogram examination, she was proposed for coronary fistula closure. Coronary CT was performed for procedure planning and allowed the identification of a second unsuspected fistula from the right coronary to the right pulmonary artery...

Pulmonary arteriovenous malformations are rare vascular anomalies of the lung, only a few cases of which have been diagnosed prenatally. The diagnostic clue for prenatal diagnosis was cardiomegaly with a particularly enlarged left atrium. All previous cases of pulmonary arteriovenous malformations diagnosed prenatally have been reported as an isolated anomaly or in association with simple heart defects. We here describe the first case of a pulmonary arteriovenous malformation with a complex heart defect that was diagnosed prenatally at 21...

BACKGROUND AND OBJECTIVES: Thrombosis is an uncommon disorder in children. Patients with slowflow vascular malformations have higher risk of developing localized intravascular coagulation, which is closely related to the presence of thrombotic events. These episodes cause pain, can be recurrent and determine a clear deterioration in the quality of life. Moreover, serious complications such as pulmonary thromboembolism and eventually death have been described. The aim of the present study is to identify clinical and laboratory risk factors associated with thrombotic events in pediatric patients with vascular malformations...

TA-TMA is a post-hematopoietic stem cell transplant complication with clinical features of hemolytic anemia and thrombocytopenia. A 26-month-old child who had had an allogeneic transplant for treatment of DBA developed severe TA-TMA with heavy red blood cell and platelet transfusion dependence. Incidentally, he was found to have a lung sequestration. TA-TMA resolved and transfusion dependence resolved after resection of the sequestration. The finding suggests the malformation vasculature was selectively vulnerable to the trigger of TA-TMA-raising perhaps a clue to basic pathophysiology of TA-TMA and/or vascular malformations...

REVIEW
Elizabeth F Sheybani, Eric P Eutsler, Oscar M Navarro
The diagnosis of soft-tissue masses in children can be difficult because of the frequently nonspecific clinical and imaging characteristics of these lesions. However key findings on imaging can aid in diagnosis. The identification of macroscopic fat within a soft-tissue mass narrows the differential diagnosis considerably and suggests a high likelihood of a benign etiology in children. Fat can be difficult to detect with sonography because of the variable appearance of fat using this modality. Fat is easier to recognize using MRI, particularly with the aid of fat-suppression techniques...

OBJECTIVE The current management of atlantoaxial dislocation (AAD) focuses on the C1-2 joints, commonly approached through a posterior route. The distinction between reducible AAD (RAAD) and irreducible AAD (IrAAD) seems to be less important in modern times. The roles of preoperative traction and dynamic radiographs are questionable. This study evaluated whether differentiating between the 2 groups is important in today's era. METHODS Ninety-six consecutive patients with congenital AAD (33 RAAD and 63 IrAAD), who underwent surgery through a posterior approach alone, were studied...

Schwartz-Jampel syndrome is a rare autosomal recessive disorder with joint contractures, generalized myotonia, skeletal anomalies, and facial dysmorphism. The patients with Schwartz-Jampel syndrome have muscle stiffness and electromyography reveals complex, repetitive discharges as myotonic discharges. It is unusual for a Schwartz-Jampel syndrome case to have recurrent gastrointestinal bleeding episodes. The stable endothelial barrier is provided by perlecan which is an important component of vascular structures...

Abernethy malformation, also known as congenital extrahepatic portosystemic shunts (CEPS) is a rare clinical entity and manifests with different clinical symptoms. CEPS are abnormalities of vascular development where there is shunting of portal blood into the systemic venous system. Multidetector computed tomography (MDCT) is a fast and effective modality for evaluation of CEPS. CT displays all the information desired by the surgeon as well as the clinician including the anatomy of the splenic and superior mesenteric veins, size and site of the shunt, presence or absence of the portal vein radicles, and helps to plan the therapy and even the follow-up of these patients...

Increased circulating catecholamines have been linked with cardiovascular anomalies as well as with peripheral vascular diseases. Although the roles of epinephrine and norepinephrine have received considerable attention, the role of the other catecholamine, dopamine, has been less studied. Since dopamine is a potent endogenous inhibitor of angiogenesis and as angiogenesis is essential for ischemic healing, we therefore studied the role played by dopamine during ischemic healing using dopamine D2 receptor knockout (KOD2) mice...

Congenital anomalies of the inferior vena cava (IVC) are rare but important problems in living donors for kidney transplantation, especially in cases of a short left renal vein and accompanying vascular and urological anatomic variations. However, the clinical impacts of IVC anomalies in deceased donors have yet to be reported. The unexpected presence of an IVC in an unusual position poses challenges to surgeons and increases the risk of bleeding during organ removal. Accompanying vascular variations can cause unexpected bleeding and injury and therefore technical complications in procurement and subsequent implantation...
