Total temporary occlusion of blood flow for several hours to treat a giant deep arteriovenous malformation: A series of multiple operations to save a young life

چکیده
BACKGROUND The treatment of giant deep arteriovenous malformations (AVMs) remains challenging. CASE DESCRIPTION We report a case of giant deep AVM diagnosed in a 9-year-old girl, for whom the AVM rupture occurred 9 years later. At the age of 9, the girl developed mild left hemiparesis. Magnetic resonance imaging revealed a giant deep AVM. The patient underwent one course of stereotactic radiotherapy followed by serial imaging. At the age of 18, we admitted her to our department with left hemiparesis and a loss of consciousness. Computed tomography showed intracerebral hemorrhage related to AVM. The treatment process proved challenging, with recurrent intracerebral hemorrhages. During the second operation, we used total temporary occlusion for almost 4 hours. Eventually, after 4 rounds of embolizations, 4 microsurgical operations, and a month-and-a-half after admission, AVM was successfully occluded. Five years after this treatment, the patient regained the ability to walk without assistance, although a moderate disability with visual changes remained (Modified Rankin Scale score 3). CONCLUSION This case illustrates that the cumulative risk of rupture of a high-grade AVM in young patients is evident, while treatment may prove successful with satisfactory results.

Simulation study of Hemodynamic in Bifurcations for Cerebral Arteriovenous Malformation using Electrical Analogy
Background and Objective: Cerebral Arteriovenous Malformation (CAVM) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. Measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in Arteriovenous Malformation patients. The vessel geometry in CAVM patients are...

Background and purpose: Pulmonary arteriovenous malformations (PAVM) are lung lesions that affect most of the periphery of the lower lobes, and are manifested by dyspnea, hemoptysis, and hemothorax. Pregnancy is one of the conditions in which these malformations appear due to hemodynamic changes and hormonal factors such as increased levels of estrogen. This paper presents the case of a pregna...

A scrotal arteriovenous malformation (AVM) is a rare condition representing an abnormal connection between the arterial and venous systems of vessels supplying the scrotum. Scrotal AVMs are usually treated via transcatheter embolization, surgical extirpation, or a combination of the two approaches. A 41-year-old man developed a life-threatening hemorrhage from a scrotal AVM. After hemodynamic s...
