Superficial occipital artery: report of a rare case and literature review

We report a rare case of an aberrant occipital artery found during routine dissection of the right posterior neck and the occipital region of an embalmed 67-year-old Caucasian male cadaver. The right occipital artery, having considerable size (diameter 4 mm), arose from the postero-lateral side of the external carotid artery just above the posterior belly of the digastric muscle. Consequently, the aberrant occipital artery turned laterally around the posterior belly of the digastric and the stylohyoid muscles, reaching the subcutaneous layer as it passed transversely over the upper attachment of the sternocleidomastoid muscle. Distally, the artery showed typical branching pattern. Detailed knowledge about the basic anatomy of the occipital artery, as well as its variations, are highly important in preventing complications during extra-to-intracranial bypass surgery and therapeutic embolization via this vessel. A careful preoperative examination of the artery is necessary to reveal some of its rarest anatomical variation

Post-traumatic giant fistula between the aorta and the left renal vein: a case report.

A unique case of post-traumatic aorto-left renal vein fistula (ALRVF) is presented. Some specific features of diagnosis and treatment of post-traumatic and postaneurysm ALRVF are discussed. The importance of careful planning of the operative strategy is emphasized because substantial blood loss may lead to serious intraoperative complications and frequently necessitates autohemotransfusion. The 10-year follow-up confirmed that direct reconstruction was the appropriate procedure, with no indications that an endovascular procedure would have been preferable. Direct reconstruction may also be valuable in treating postaneurysm ALVRF.
