    The authors present six cases of subarachnoid hemorrhage secondary to rupture of an aneurysm of the pericallosal artery. Four of these were of the berry type and were located at the genu of the corpus callosum; in two instances the aneurysm was found at the bifurcation of an azygous or a bihemispheric pericallosal artery respectively. A fifth lesion was of the fusiform type and the sixth one represented most probably a false aneurysm. All patients have been operated upon, but in three only clipping of the neck was feasable. In the remainder one pericallosal or the azygos artery was occluded intentionally. Postoperatively, severe mental perturbation, incontinence and seizures were encountered, but all symptoms cleared during the follow-up period, and subarachnoid hemorrhage never recurred.

    The Arch of Aorta

    The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
    Encircling the heart, the coronary arteries form a ring-like structure before...

    Arteries of the Head and Neck

    The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
    The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

    Aneurysm I: Introduction

    An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

    Aneurysm II: Clinical Manifestations and Diagnostic Studies

    Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

    Aneurysm III: Interprofessional Care

    Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
    Hemorrhagic Stroke l: Introduction01:17

    Hemorrhagic Stroke l: Introduction

    A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
