We describe the case of a neonate with signs of heart failure. Echocardiography showed a structural normal heart shape with left ventricular dysfunction. At 2 months of age, a vein of Galen arteriovenous malformation was diagnosed through a brain magnetic resonance imaging. Embolization therapy was accomplished and a clinical and neurological follow-up was started. This clinical case highlights how important it is considering an intracranial cause in the differential diagnosis of neonatal congestive heart failure (CHF). We performed a narrative minireview of the literature about treatments and outcome of this malformation in association to CHF, to point out how complex the diagnosis of vein of Galen aneurysmal malformation (VGAM) may be and how an early diagnosis is important for its management.

Cobb syndrome is a rare neurocutaneous disorder characterized by spinal vascular abnormalities in association with a vascular lesion of the skin at the same metamere. Patients present after the onset of symptoms such as paraplegia, back pain, and, less commonly, fatigue due to heart failure. Available treatment options to date have included neurosurgical resection and endovascular embolization. We present a patient with Cobb syndrome with a progressively symptomatic arteriovenous malformation involving the thoracic vertebrae and left hemithorax, with extensive blood supply from the T3 to T10 intercostal arteries, and demonstrate successful endovascular thoracic stent graft placement and coil embolization.

A 54-year-old man was admitted to our hospital with dyspnea and heart failure. Contrast-enhanced computed tomography showed a giant pelvic arteriovenous malformation (AVM) fed by the left internal iliac artery (IIA), right IIA, and inferior mesenteric artery. (IMA). The AVM was treated with selective embolization via the left IIA. Time-resolved three-dimensional phase-contrast magnetic resonance imaging (4D-flow MRI) visualized a gradual flow reduction in the left IIA, whereas the flow in the IMA and right IIA increased relatively. After four sessions, the patient experienced symptom relief and the blood level of N-terminal prohormone brain natriuretic peptide decreased. To the best of our knowledge, we present the first reported use of 4D-flow MRI to quantitatively assess flow reduction in the case of pelvic AVM after embolization.

Capillary malformation-arteriovenous malformation (CM-AVM) syndrome is a newly described entity characterized by autosomal dominantly inherited multifocal capillary malformations caused by RASA1 mutations (CM-AVM1) or EPHB4 mutations (CM-AVM2). Concurrent high-flow vascular anomalies in the brain are often present in the form of intracranial AVM or arteriovenous fistula (AVF). These high-flow lesions are often identified at or soon after birth because of the characteristic unique capillary malformations or a systemic disorder due to a high-flow shunt, such as respiratory distress or heart failure. However, de novo intracranial AVMs have not been reported in patients with CM-AVM syndrome. Herein, we report the case of a six-year-old boy with CM-AVM1 who had been treated for an intracranial pial arteriovenous fistula approximately five years previously, in whom a de novo intracranial AVM was identified on a follow-up angiographic study. To the best of our knowledge, this report is the first to document a de novo intracranial AVM in a patient with CM-AVM. We recommend careful neuroimaging follow-up even if initial neuroimaging screening is negative because of the risk of de novo AVM development.

An 8-day-old neonate was presented with severe respiratory distress and diagnosed as primary pulmonary hypertension of the newborn on functional echocardiogram. Evaluation showed bounding pulse, enlarged umbilical cord, and bruit over the periumbilical region. Transthoracic echocardiography and CT angiogram showed a large fistulous communication between the umbilical vein and artery suggestive of congenital umbilical arteriovenous malformation leading to high-output cardiac failure and pulmonary artery hypertension. The patient was stabilised with medications and ventilation. Transcatheter closure of communication was done using coils, vascular plug, and KONAR-MFTM device. The patient improved from heart failure soon after the procedure and thriving normally at 6 months of follow-up.
