Leg weakness most commonly arises from nerve compression in the lower back. Hence, pain in the lower back region should not be ignored, especially if it is longstanding. The shooting pain, which travels from the lower back to the knee or the ankle, is because of the irritation of the nerves caused by compression.
Heart disease is a serious medical condition in dogs, cats and humans. Cats do not normally develop arteriosclerosis or coronary artery disease, which are both common diseases in humans. In general terms, heart disease can be divided into two categories, congenital and adult onset forms.
Acta Neurologica Taiwanica Vol 21 No 1 March 2012. Abstract. Congenital vertebral artery (VA) hypoplasia is an uncommon embryonic variation of posterior circulation. The frequency of this congenital variation was reported to be 2-6% from autopsy and angiograms. Is it a congenital risk factor of ischemic stroke? In this review, we gave an overview of the literature concerning vertebral artery hypoplasia. VA hypoplasia served as an independent factor of a reduction of the posterior. circulation blood flow velocity. VA hypoplasia can play a negative role in cases of occlusion of a major. brain vessel since it limits the potential of compensatory blood circulation.
