Massive Aneurysm in a Persistent Sciatic Artery.
Summary of "Massive Aneurysm in a Persistent Sciatic Artery."
Persistent sciatic artery (PSA) is an exceptionally rare embryological vascular anomaly with a reported incidence, based on angiographic series, of between 0.01 and 0.05%. We report a case of a patient with bilateral PSAs and a unilateral 12-cm aneurysm arising from the left PSA. As with our case, most PSAs are among the dominant arteries that supply blood to the lower limb with aneurysm formation occurring in up to 40% of cases. The femoral artery is often hypoplastic. Presentation usually includes symptoms and signs of an enlarged buttock mass, sciatic nerve compression, and distal limb ischemia. An interposition inlay graft is the preferred method of surgical repair. Dissection of the aneurysm is not recommended because of risk of damage to the sciatic artery. Endovascular stent placement is an accepted method of repair but does not deal with any local symptoms of the expanding aneurysm.

A persistent sciatic artery is a rare vascular anomaly in which the sciatic artery, which involutes in the embryonic stage, persists as the blood supply to the lower limb. This vascular anomaly is oft...
In this report, a case of blue toe syndrome related to persistent sciatic artery pseudoaneurysm in a 63-year-old woman, which was diagnosed by selective angiography, is presented. The pseudoaneurysm w...
Persistent sciatic artery is a very rare clinical entity. Those of us who have not seen the lesion regard this as a condition which is described in the literature through less than 200 cases. We repor...
The persistent sciatic artery (PSA) is a rare arterial variant. Patients may present with a spectrum of atherosclerotic disease, but aneurysm formation with thromboembolic complications is more common...
Purpose : To describe the successful management of a symptomatic persistent sciatic artery (PSA) aneurysm using the Multilayer Aneurysm Repair System (MARS). Case Report : A 50-year-old man with histo...
Sciatic nerve blocks are frequently used for anesthesia or analgesia for surgery of the lower legs. Currently, if ultrasound is used to find the sciatic nerve, the leg must be raised to l...
Traumatic disruption of iliofemoral arterial segment is often associated with multiple injuries, massive hemorrhage, state of shock, and loss of blood supply to the ipsilateral lower extre...
The purpose of this trial is to assess whether the new endovascular repair technique of the abdominal aortic aneurysm (AAA) is an adequate substitute of the conventional AAA repair.
After endovascular abdominal aortic aneurysm repair, life-long follow-up is needed to monitor the effectiveness of exclusion of the aneurysm sac from blood flow. For this reason, aneurysm ...
This purpose of this study is to measure the strength of tissue allografts that have been in the body various lengths of time.

Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation.
Ischemia or infarction of the spinal cord in the distribution of the anterior spinal artery, which supplies the ventral two-thirds of the spinal cord. This condition is usually associated with ATHEROSCLEROSIS of the aorta and may result from dissection of an AORTIC ANEURYSM or rarely dissection of the anterior spinal artery. Clinical features include weakness and loss of pain and temperature sensation below the level of injury, with relative sparing of position and vibratory sensation.

Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.
