The International Classification of Headache Disorders (ICHD-3 beta) includes headache attributed to intracranial endovascular procedures (EVPs). The aim of this review is to describe the clinical and pathophysiological aspects of headache related to vascular lesions and EVPs. Current studies regarding this issue are contradictory, although generally favouring headache improvement after EVPs. Further large studies are needed to adequately assess the effect of EVPs on headache.

A few clinic-based magnetic resonance imaging studies report an increased risk of signal abnormalities in migraineurs brain's white matter, especially in migraine with aura subjects. A vascular genesis has been hypnotized and migraine with aura was considered an independent risk factor for stroke. Available data of magnetic resonance imaging alterations are often nonspecific and sometimes controversial. The aim of our study is to investigate migraine with aura patients with standardized brain magnetic resonance imaging to detect and to quantify the presence of white matter lesions and to analyze their relation with clinical data...

Sulfur dioxide (SO₂) is a toxic gas and air pollutant. The toxic effects of SO₂ have been extensively studied. Oxidative damage due to SO2 can occur in multiple organs. Inhaled SO₂ can also cause chromosomal aberrations, DNA damage and gene mutations in mammals. However, SO₂ can also be generated from the sulfur-containing amino acid, L-cysteine. Recent studies have shown that SO₂ has a vasorelaxant effect, and ameliorates pulmonary hypertension and vascular remodeling. SO₂ can also reduce lung injury and myocardial injury in rats...

Chronic thyroiditis may present a focal lesion, often-palpable abnormality, simulating nodular disease. The number and morphology of the Hürthle cells (HC) vary in the thyroid aspirate. Distinguishing between neoplastic and non-neoplastic HC lesions is difficult when using the fine-needle aspiration cytology (FNAC). We present the case of a 46-year-old female with a large right nodular goiter and hypothyroidism and high titer of anti-thyroid peroxidase antibody (TPO). The thyroid ultrasound showed a large well-defined nodule (more than 6...

Squamous cell carcinoma (SCC) of the lip represents 15-30% of SCC of cephalic extremity, located on the lower lip in about 90% of cases. The present paper aimed to define the profile of SCC of the lip with major risk factors. The study included 20 selected cases diagnosed with lower lip SCC, using a panel of antibodies which addressed cell proliferation (Ki67), perturbation of the cell cycle (p53), angiogenesis (VEGF - vascular endothelial growth factor), factors related to tumor cell interaction with the extracellular matrix (CD44)...

Various forms of vascular lesion affect the head and neck region. The head and neck vascular lesions are classified into neoplasms and malformations. Neoplasm presents either as hemangioma or lymphangioma; neoplasm usually presents in young age compared with vascular malformation. A 9-year-old female patient presented to the outpatient clinic referred from the department of pedodontics after extraction of a right mandibular second deciduous molar. Extraction was done by dental GP in outpatient clinic. Massive bleeding followed the extraction...

Flow conditions critically regulate endothelial cell functions in the vasculature. Reduced shear stress resulting from disturbed blood flow can drive the development of vascular inflammatory lesions. On endothelial cells, the transmembrane chemokine CX3CL1/fractalkine promotes vascular inflammation by functioning as a surface-expressed adhesion molecule and by becoming released as soluble chemoattractant for monocytic cells expressing the receptor CX3CR1. Here, we report that endothelial cells from human artery, vein, or microvasculature constitutively express CX3CL1 when cultured under static conditions...

Exolysin (ExlA) is a recently-identified pore-forming toxin secreted by a subset of Pseudomonas aeruginosa strains identified worldwide and devoid of Type III secretion system (T3SS), a major virulence factor. Here, we characterized at the ultrastructural level the lesions caused by an ExlA-secreting strain, CLJ1, in mouse infected lungs. CLJ1 induced necrotic lesions in pneumocytes and endothelial cells, resulting in alveolo-vascular barrier breakdown. Ectopic expression of ExlA in an exlA-negative strain induced similar tissue injuries...

OBJECTIVES: Using intravascular ultrasound (IVUS), the authors compared outcomes by observed wire position (intraplaque vs. subintimal) achieved during successful chronic total occlusion (CTO) lesion treatment. BACKGROUND: Recent successes in CTO percutaneous coronary intervention (PCI) have used both intraluminal and subintimal wire tracking to improve procedural success. IVUS may be used to determine the course of wire tracking after crossing a CTO. METHODS: From March 2014 to March 2016, data were collected into a single-center database from 219 patients undergoing CTO PCI with concomitant IVUS imaging...

BACKGROUND: Magnetic resonance imaging (MRI) and computed tomography (CT) angiography have now largely replaced interventional angiography in the diagnoses and follow up of Takayasu arteritis (TAK) but data on the effects of this change of imaging method on diagnostic delay and vascular damage, and detailed data on the effect of different treatment regimens on the accumulation of vascular damage are missing. The aim of this study was to assess time trends in diagnostic delay, therapeutic approaches, arterial lesion accrual, persistent disease activity and remission rates in TAK...

BACKGROUND: Around 47-74% of patients with hereditary hemorrhagic telangiectasia (HHT) have hepatic vascular malformations (HVMs); magnetic resonance images (MRI) of the central nervous system (CNS) might show in T1 sequences a hyper-intensity signal in different areas, mainly in the basal ganglia (BG) as consequence of manganese (Mn) deposits as observed in cirrhotic patients. These patients might suffer from different neuropsychiatric disorders (hepatic encephalopathy). In HHT patients, even in the presence of hepatic shunts, hepatocellular function is usually preserved...

Presented is a case of a hepatic calcified mass complicating umbilical vein catheterization in a neonate and diagnosed by wedge biopsy. Wedge biopsy of the hepatic mass, situated in proximity to the falciform ligament, revealed expansion of portal tracts by fibrosis and calcification. Some aggregates of calcified material appeared in ectatic vascular spaces. The biopsy findings accounted for the radiographic appearance of the mass and the constellation of features were deemed indicative of calcification secondary to umbilical vein catheterization...

BACKGROUND: Intraoperative angiography is routinely utilized for aneurysms and arteriovenous malformations (AVMs) to verify complete occlusion and resection. Surgery for spinal and posterior fossa neurovascular lesions is usually performed in prone position. Intraoperative angiography in the prone position is challenging and there is no standardized protocol for this procedure. OBJECTIVE: To describe our experience with intraoperative angiography in the prone and lateral positions, using upper extremity arterial access...

Hepatic angiosarcoma is a rare, aggressive, malignant neoplasm with fewer than 50 cases reported in children. Prognosis is poor, with a minority surviving beyond 2 years after diagnosis. We report eight cases of pediatric hepatic angiosarcoma, diagnosed at a mean age of 3 years. Seven were initially diagnosed with an infantile hepatic hemangioendothelioma (IHHE) or hemangioma and the eighth with a "vascular tumor." Two patients, who received liver transplant, survived. We suggest hepatic hemangiomas can rarely transform into angiosarcomas and a subset of IHHEs (Type II) are actually a low-grade form of angiosarcoma rather than a benign lesion...

Following the introduction of the first laparoscopic liver resection, after ∼25 years, a critical reappraisal seems to be warranted. Liver resection represents the first choice for curing early hepatocellular carcinoma (HCC) allowing a curative chance also in selected patients with intermediate stage tumors. The criteria for liver resectability by laparoscopy remains the same for open surgery, which is oncological criteria (absence of extrahepatic tumor location; completely resectable R0 resection), anatomic (resectability of involved segment with its own blood surely and biliary drainage; absence of vascular invasion of portal or hepatic veins) and technical (possibility to leave in place a residual volume ≥40%)...

Endoscopic ultrasound (EUS) has been increasingly used for the diagnosis and staging of pancreatic cancer. It has recently become the modality of choice in assessing pancreatic lesions overcoming other traditional modalities. Typically lesions located at the tail of the pancreas are best accessed through the stomach. We present a patient with pancreatic tail mass occurring in the setting of a large hiatal hernia, intrathoracic stomach, and severe lumbar levoscoliosis. Due to altered anatomy and extensive vascular connections of the mass, any surgical or radiological intervention was considered high risk for the patient...

Placental mesenchymal dysplasia (PMD) is an uncommon vascular anomaly of the placenta characterized by placentomegaly with multicystic placental lesion on ultrasonography and mesenchymal stem villous hyperplasia on histopathology. Placental mesenchymal dysplasia should be considered in the differential diagnosis of cases of multicystic placental lesion such as molar pregnancy, chorioangioma, subchorionic hematoma, and spontaneous abortion with hydropic placental changes. However, lack of high-velocity signals inside the lesion and a normal karyotype favor a diagnosis of PMD...

Primay melanoma of the cavernous sinus is very rare with only few cases reported in the literature. We present the cross-sectional imaging findings of this rare tumor. The differential diagnosis for cavernous sinus mass lesion is wide as it contains vital neurovascular structures that may be affected by vascular, neoplastic, infective, and infiltrative lesions arising in the cavernous sinus proper or via extension from adjacent intra and/or extracranial regions. Radiologic imaging can narrow the differential diagnosis, however, imaging cannot definitely reach single diagnosis if they present in atypical form with hemorrage and cystic degeneration...

Castleman's disease (CD) is a rare lympho-proliferative disorder due to faulty immune regulation resulting in proliferation of lymphatic tissue. The vascular supply to these lesions have been reported to arise from the bronchial, internal mammary and the intercostal arteries. We report a case of hemoptysis secondary to intrathoracic CD with vascular supply arising from the left inferior phrenic artery which was successfully embolised with polyvinyl alcohol (PVA) particles.
