Background: A coronary artery fistula is an abnormal connection between one or more coronary arteries and a cardiac chamber or great vessel, often discovered incidentally through cardiac imaging. Although coronary artery fistulas are typically asymptomatic during the first two decades of life, particularly when small, they can become clinically significant over time.

Case Presentation: We present the case of a 71-year-old female patient with a history of exertional dyspnea.

A 58-year-old man was admitted for stable angina. The coronary angiogram revealed a coronary-pulmonary fistula with a nonsignificant atheroma. We decided to perform percutaneous embolization of the fistula in view of the symptoms and the hemodynamic assessment findings.

Objective: Intracranial dural arteriovenous fistula (DAVF) is mainly treated with an endovascular approach. Two major treatment advances include transvenous embolization (TVE) with coils in 1989 and, more recently, transarterial embolization with Onyx. The aim of this study was to present a large monocentric series of patients with DAVF treated with TVE.

Intrahepatic lesions in adults, commonly named hepatic hemangioma, should be called Intrahepatic Venous Malformations (IHVM), or Giant Intrahepatic Venous Malformations (GIHVM) when larger than 10 cm according to the ISSVA classification (International society study group for vascular anomalies). Localized coagulation disorders (LIC) in patients with venous malformations are quite commonly associated in venous malformations, they result in decreased fibrinogen (< 2g/l) and elevated d-dimers (> 1500 ng/ml) and might be responsible of intralesional thrombotic, pain or bleeding episodes.We report a case report of a 41 y/o patient that presented with right hypochondrium pain episodes discovering an unknown GIHVM on ultrasound imaging with a prior history of uterine bleeding episodes and multiples miscarriages.

Article Synopsis
  • Pelvic and abdominal arteriovenous malformations (AVM) are uncommon but serious vascular conditions that can lead to significant health issues.
  • They can occur on their own (sporadic) or as part of a genetic syndrome, and may cause symptoms due to increased blood flow that can lead to heart failure.
  • The preferred treatment method is endovascular management, which is often part of a team-based approach to care.

Objective: To determine long term safety and efficacy of endovascular treatment of spinal cord arteriovenous malformations (AVMs), with calibrated particle embolization as a firstline approach.

Methods: We reviewed clinical and imaging data of consecutive patients who underwent endovascular treatment for both nidal and fistulous type spinal cord AVMs in our center, from 1990 to 2015. Outcome at the last follow-up was assessed by an independent observer.

Article Synopsis
  • The study aimed to investigate how common and how effectively spontaneous intracranial artery dissection (IAD) is treated during acute ischemic strokes.
  • Researchers reviewed patient data from a thrombectomy center and found IAD in 3% of patients, often linked to previous extracranial dissections.
  • The findings suggest that stenting is an effective treatment, improving recanalization rates and potentially lowering the chance of stroke recurrence, but more research is needed to confirm stenting as a first-line treatment.

Background: Congenital arteriovenous malformations (AVMs) are infrequent but represent a serious medical challenge because of their unpredictable progression and high hemodynamic activity.

Case: We report on the treatment of a voluminous vulvar AVM in a 16-year-old girl. After failure of medical therapy, we performed a radical surgical resection with preliminary embolization and flap reconstruction.

We examined the effectiveness of uterine artery embolization (UAE) as a primary treatment for small symptomatic myomatas (<50 mm diameter). One hundred patients aged from 29 to 68 years underwent UAE between 01/01/99 and 12/31/2002. Efficacy was judged by physical examination and imaging studies at 6 to 12 months.

Purpose: To analyze anatomic and clinical results and factors predictive of outcome in treatment of basilar tip aneurysms with Guglielmi detachable coils (GDCs).

Materials And Methods: During 6 years, 55 unselected consecutive saccular aneurysms in 53 patients (mean age, 47 years) were treated with GDC occlusion. Forty-one (75%) aneurysms were ruptured (Hunt-Hess and Fisher grades were assigned in patients); 14 (25%), unruptured.

Purpose: To report the endovascular occlusion of an anastomotic false aneurysm of the ascending aorta.

Case Report: A 51-year-old patient developed an anastomotic false aneurysm at the level of the aortic arch after surgical replacement of the aortic root and arch for aortic dissection. The aneurysm expanded after 6 months and because of its saccular shape was treated by selective occlusion with detachable microcoils.

Purpose: To investigate the role of urokinase selectively perfused into the ophthalmic artery as an emergency treatment for combined central retinal arterial obstruction (CRAO) and central retinal venous obstruction (CRVO).

Materials And Methods: Over a 6-year period, 11 consecutive patients presented with recent combined CRAO and CRVO (< or =72 hours). Urokinase (300,000 IU) was selectively perfused via the femoral artery into the ophthalmic artery for 40 minutes.

Purpose: To evaluate the endovascular treatment (EVT) of mycotic aneurysms (MAs).

Materials And Methods: Clinical and radiologic data of 18 MAs treated with EVT were retrospectively reviewed. There were 14 patients (11 men, three women), ranging in age from 28 to 64 (mean age, 44 years).
