Is having a leaking aortic valve related to an aortic aneurysm?

Sometimes. Thoracic aortic enlargement and aneurysm can dilate the aortic valve annulus and leakage can occur. Also with aortic valvular stenosis, post stenotic dilation can occur. Abdominal aneurysms are not usually related to valve issues.
It can be. It can be. If the aneurysm involves the ascending aorta and the aortic root, it can cause aortic valve insufficiency (leaking valve).

Variable recs. Recommendations continue to evolve. If your aorta grows more than 0.5 cm/yr->operate. If your aorta is over 5.5 cm->operate. If you have other risk factors, maybe operate at 5.0 cm. Control your blood pressure, use beta-blockers. A very important corollary to these recommendations is to choose your surgeon carefully. Some surgeons have much better outcomes than others.

Valve is problem. Aneurysm is small and secondary to turbulant blood flow across the abnormal valve. Bicuspid valves generally begin to calcify in the 5th and 6th decades of life leading to Aortic Valve stenosis. You should have a cardiologist and get annual echocardiograms and when the gradient across the valve is > 40mmHG and you have symptoms the valve should be replaced. Tx of aneurysm unnecessary at that size. Read more...
Expansion. Agree with Dr. Sheppard and would add that you need evaluation to know the rate that the aneurysm is growing as that may also influence timing of intervention. Read more...

Is bruising in the periumbilical area a common sign of a leaking aortic aneurysm?

Very Late sign. Since the abdominal aorta is in the retroperitoneum, bleeding most often occurs into the space near the kidneys. Early symptoms are abdominal, back or flank pain. It is more common to have bruising of the flanks (grey turner's sign). It is possible for the blood to track all the way up to the umbilicus, but this would be a pretty late sign. Hopefully you would be in the or by then! Read more...
No. The abdominal aorta is deep in the abdomen and situated on the spine. A rupture can eventually lead to bruising on the back, days later and if the patient survives, but not on the abdominal wall. Pain is the usual symptom of an aneurym leak and immediate medical attention should be sought. Read more...
