Abstract:
A 4-year-old dog was presented for acute, progressive tetraparesis and cervical hyperesthesia. Symmetrical tubular structures coursing along the lateroventral aspects of the spinal cord at the fourth and fifth cervical vertebrae were identified in magnetic resonance images. At necropsy, vertebral arteries and their spinal branches were severely ectatic bilaterally, and the cervical spinal cord was compressed. Histologically, the ectatic branches of the vertebral and ventral spinal arteries were surrounded by fibrosis with scant mononuclear cell infiltrates and hemorrhage. Spinal branches of th

Abstract:
Despite advances with new generation stents, there remains some atypical coronary anatomy where optimal stenting continues to be a challenge; such as stent sizing in large, ectatic or aneurysmal vessels; tapered vessels; and in vasoconstricted arteries such as in ST-segment elevation myocardial infarction or chronic total occlusions. Balloon-expandable stents are tubular and cannot easily accommodate vessel diameter variations; thrombotic vessels increase the risk of distal embolisation and no-reflow; positive remodelling and vasodilation often result in subsequent malapposition; and patients

Abstract:
Purpose: To investigate the natural history of dilated common iliac arteries (CIA) exposed to pulsatile blood flow after endovascular abdominal aortic aneurysm repair (EVAR) and the suitability of ectatic iliac arteries as sealing zones using flared iliac limbs. Methods: Follow-up computed tomograms of 102 CIAs in 60 EVAR patients were investigated. Diameter changes in CIAs ≤16 mm (group 1) were compared with changes in vessels where a dilated segment >16 mm in diameter continued to be exposed to pulsatile blood flow (group 2). Within group 2, cases in which the stent terminated proximal to

Abstract:
Abstract We report the case of a 43-year-old quadriplegic woman with bilateral vulvar enlargement. The clinical impression was labial hypertrophy, but the microscopic features mimicked aggressive angiomyxoma because of the location, hypocellular proliferation of fibroblastic cells in an edematous-myxoid stroma, and vessels with perivascular collagen deposition, which simulated the thick-walled vessels of aggressive angiomyxoma. Since the lesion lacked true thick-walled vessels and contained ectatic tortuous lymphatics, the pathologic interpretation was lymphedema. This vulvar lesion should be

AbstractA case is presented of a 36-year-old male with narrowing of the external meatus due to a diffuse neurofibroma. This unusual variety of neurofibroma spreads superficially and has many ectatic blood vessels. The size, vascularity, uncertain edges and a tendency to recur makes surgical removal difficult. The treatment options are discussed.

Abstract:
✓ Neurovascular compression syndromes are usually treated by interposing Teflon felt or padding or some other implant between the offending vessel and the nerves. However, this cannot be done in some cases in which ectatic vertebrobasilar arteries are involved. In these instances, alternative techniques must be used. The authors report the use of a sling made of Prolene to reposition the vertebral artery in two patients with neurovascular compression disorder. The clinical results were gratifying, with complete resolution of the patients' symptoms. Compression by large vessels is an uncommon b

Abstract:
Coronary angioplasty to large vessels is challenging, particularly in the setting of myocardial infarction. The traditionally used devices are insufficient for the treatment of vessels that exceed 4 or 5 mm in diameter, even more so in the presence of high thrombotic content. On this occasion, we present the resolution of an acute coronary syndrome with ST-segment elevation, involving a large ectasic Right Coronary artery, with the sirolimus-eluting stent X-POSITION S Stentys.

Abstract:
Introduction: Coronary artery ectasia (CAE) refers to a 1.5 fold increase in coronary artery diameter compared to the normal segment. Although the underlying pathophysiological mechanism is not fully elucidated, coronary atherosclerosis is thought to play a role in more than half of the cases. Triglyceride glucose (TyG) index is an indicator of insulin resistance. In the present study, aimed to evaluated TyG index values in CAE cases and find if a predictive value of TyG index existed. Patients and Methods: Sixty-one patients with CAE (study group) and 64 patients with normal coronary arteries

Abstract:
Acquired lymphangiectasia is an unique entity encountered by an urologist which is marked by occlusion of lymphatics associated with abnormal permanent dilation of cutaneous lymphatics. There is presence of thin-walled ectatic vessels in the superficial and mid dermis, which develops later in life. Trauma, infection, radiation or surgery are important causes of this rare aetiology. Diagnosis is always demanding, as it closely resembles many benign aetiology. Meticulous decision-making and appropriate treatment should be chosen for the management.

Abstract:
Giant cell arteritis (GCA), also known as temporal arteritis or Horton disease, is categorized as a large- and medium-sized vessels vasculitis. Systemic symptoms are common in GCA and although vascular involvement may be widespread, the cranial branches of the aortic arch are responsible for the hallmark symptoms of GCA: headache, jaw claudication and ocular symptoms, particularly visual loss. The large vessel (LV)-GCA phenotype may differ or overlap from cranial arteritis. Clinical consequences of LV-GCA comprise aneurysms and dissections of the aorta, as well as stenosis, occlusion and ectas

Abstract:
Abstract Port wine stain (PWS) birthmarks are a congenital and progressive vascular malformation of the dermis, involving capillaries, which occurs in approximately 0.7% of children. The objective of laser surgery for this and similar conditions is to cause selective thermal damage, thrombosis, and, eventually, permanent photocoagulation in the PWS vessels. To achieve this, the radiated laser light is set at a specific wavelength, which is highly absorbed by the blood vessels’ hemoglobin (the major chromophore in blood). Unfortunately, the PWS vessels do not absorb all energy radiated — a sign
