Herein is reported a rare case of right persistent sciatic artery (PSA) in the cadaver of a 96-year-old woman who did not have any clinical manifestations related to this anomaly when alive. The anomalous PSA originated from the internal iliac artery, directed toward the infrapiriform foramen, and descended the dorsal side of the thigh. Approximately 20 mm inferior to the infrapiriform foramen, the PSA formed a relatively large aneurysm elongating for approximately 30 mm in length. It then passed under the long head of the femoral biceps muscles, and reached the popliteal fossa, maintaining a constant caliber (approx. 13 mm) as it went down distally. In contrast, the femoral artery was very narrow, and tapered at the level of the knee joint. In addition, the popliteal vein gave rise to two branches, one ran along with the sciatic artery and the other pierced the adductor muscles, and appeared on the ventral side of the thigh. It then drained into the deep femoral vein, which reached the pelvis via the femoral vein. The present case is an interesting example for clinicians who work in pelvic surgery.
Reported herein is a rare case of multiple vascular anomalies involving the vertebral vessels and the bronchial artery. In the present case the vertebral artery, which normally originates from the subclavian artery, arose directly from the cranial side of the aortic arch, just between the left common carotid and subclavian artery. Furthermore, the bilateral entry of the vertebral artery deviated to the upper level of the transverse foramen of the cervical vertebrae (C5). In addition, the left vertebral vein went through the transverse canal via the 5th and 7th transverse foramen, and drained into the left venous angle. Another conspicuous variation observed in this cadaver was the bronchial artery stemming from the left subclavian artery. This phenotype is an additional branch of bronchial arteries, which in normal cases arises from the descending aorta. These two anomalies could be explained by the deviation of the anlage for the left subclavian artery. The present report should be of interest for the clinician with regard to vascular anomalies in the neck and thoracic region, and may give insight into elucidating the developmental mechanism of angiogenesis.
