Femoral and popliteal aneurysms:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
Popliteal aneurysms may cause pain in the popliteal space when they’re large enough to compress the medial popliteal nerve and edema and venous distention if the vein is compressed. Femoral and popliteal aneurysms can produce symptoms of severe ischemia in the leg or foot due to acute thrombosis within the aneurysmal sac, embolization of mural thrombus fragments and, rarely, rupture. Symptoms of acute aneurysmal thrombosis include severe pain, loss of pulse and color, coldness in the affected leg or foot, and gangrene. Distal petechial hemorrhages may develop from aneurysmal emboli.

Aneurysm, cerebral:
Signs and symptoms
(Handbook of Diseases)
Occasionally, rupture of a cerebral aneurysm causes premonitory symptoms that last several days, such as headache, nuchal rigidity, stiff back and legs, and intermittent nausea. Usually, however, the rupture occurs abruptly and without warning, causing a sudden severe headache, nausea, vomiting and, depending on the severity and location of bleeding, altered level of consciousness (LOC), including a deep coma.
Bleeding causes meningeal irritation, resulting in nuchal rigidity, back and leg pain, fever, restlessness, irritability, occasional seizures, and blurred vision. Bleeding into the brain tissues causes hemiparesis, hemisensory defects, dysphagia, and visual defects. If the aneurysm is near the internal carotid artery, it compresses the oculomotor nerve and causes diplopia, ptosis, dilated pupil, and inability to rotate the eye.
Degrees of severity
The severity of symptoms varies from patient to patient, depending on the site and amount of bleeding. Patients with ruptured cerebral aneurysms are grouped as follows:
Grade I: minimal bleeding. The patient is alert with no neurologic deficit; he may have a slight headache and nuchal rigidity.
Grade II: mild bleeding. The patient is alert, with a mild to severe headache, nuchal rigidity and, possibly, third-nerve palsy.
Grade III: moderate bleeding. The patient is confused or drowsy, with nuchal rigidity and, possibly, a mild focal deficit.
Grade IV: severe bleeding. The patient is stuporous, with nuchal rigidity and, possibly, mild to severe hemiparesis.
Grade V: moribund (commonly fatal). If the rupture is nonfatal, the patient is decerebrate or in a deep coma.
Life-threatening factors
Generally, a cerebral aneurysm poses three major threats:
Death from increased ICP. Increased ICP may push the brain downward, impair brain stem function, and cut off blood supply to the part of the brain that supports vital functions.
Bleeding episode. Generally, after the initial bleeding episode, a clot forms and seals the rupture, which reinforces the wall of the aneurysm for 7 to 10 days. However, after the 7th day, fibrinolysis begins to dissolve the clot and increases the risk of rebleeding. This rebleeding produces signs and symptoms similar to those accompanying the initial hemorrhage. Rebleeding episodes during the first 24 hours after the initial hemorrhage aren’t uncommon, and they contribute to the high mortality associated with this disorder.
Vasospasm. The reason for this complication isn’t clearly understood. Usually, vasospasm occurs in blood vessels adjacent to the cerebral aneurysm, but it may extend to major vessels of the brain, causing ischemia and altered brain function.
Other complications of a cerebral aneurysm include acute hydrocephalus (due to abnormal accumulation of CSF within the cranial cavity because of CSF blockage by blood or adhesions) and pulmonary embolism (an adverse effect of deep vein thrombosis [DVT] or aneurysm treatment). (See Danger signals in cerebral aneurysm.)

aneurysm,ventricular:
Signs and symptoms
(Handbook of Diseases)
A ventricular aneurysm may cause arrhythmias (such as premature ventricular contractions and ventricular tachycardia), palpitations, signs and symptoms of cardiac dysfunction (weakness on exertion, fatigue, angina) and, occasionally, a visible or palpable systolic precordial bulge.
This condition may also lead to left ventricular dysfunction, with chronic heart failure (characterized by dyspnea, fatigue, edema, crackles, gallop rhythm, and neck vein distention); pulmonary edema; systemic embolization; and with left-sided heart failure, pulsus alternans.Ventricular aneurysms enlarge but rarely rupture.

Article Excerpts About Symptoms of Cerebral Aneurysm:
Before an
aneurysm ruptures, the individual may experience such symptoms as a sudden
and usually severe headache, nausea, vision impairment, vomiting, and loss
of consciousness, or the individual may be asymptomatic, experiencing no
symptoms at all. Onset is usually sudden and without warning. Rupture of a
cerebral aneurysm is dangerous and usually results in bleeding in the
brain or in the area surrounding the brain, leading to an intracranial
hematoma (a mass of blood—usually clotted—within the skull). Rebleeding,
hydrocephalus (the excessive accumulation of cerebrospinal fluid),
vasospasm (spasm of the blood vessels), or multiple aneurysms may also
occur.
