Deep femoral artery with four variations: a case report.

During our routine dissection course for students we found a complex variation of the femoral artery on the left side of a 72-year-old male cadaver. The deep femoral artery was originating from the anterior aspect of the femoral artery; the inferior epigastric and the external pudendal arteries were arising from the deep femoral artery. Besides, the lateral circumflex femoral artery was arising from the lateral aspect of the femoral artery and distal to the origin of the deep femoral artery.

Complex renal vascular variation: a case report.

As the number of renal surgical interventions increase a better understanding of the anatomy of renal arteries and their branches gain in importance. Here we describe a common trunk from the right side of the aorta ramifying into suprarenal and two renal hilar arteries in a 40-year-old male cadaver detected during dissections performed in a routine gross anatomy course. The suprarenal branch is divided into several smaller branches to supply blood to the suprarenal gland. The superior renal hilar artery gave rise to the right testicular artery and an additional suprarenal artery. The inferior renal hilar artery gave rise to one more additional suprarenal artery. The superior renal hilar artery crossed the inferior renal hilar artery. On the same side renal veins were also doubled. For better outcome interesting variations such as in this case should be kept in mind before and during any interventions involving this region.

The double deep gluteal muscles.

During routine dissections on a 65-year-old male cadaver, we encountered double piriformis, double gemelli superior and inferior, double quadratus femoris muscles in the left gluteal region. The sciatic nerve passed between the lower piriformis and the upper superior gemelli muscles infrapiriform foramen as usual. No other variation was found in the region. This rare variation may be of importance in the radiology and surgery of this region.

Branching pattern of the left coronary artery and an important branch. The median artery.

OBJECTIVE: This study was performed to assess the variations in the branching pattern and diameters of the terminal branches of the left coronary artery and discuss various names given to the third branch. METHODS: Hearts of 21 autopsies and 19 cadavers were fixed with 10% formalin and their coronary arteries were examined by dissecting the epicardium. The dissections were performed at the Anatomy Departments of Faculties of Medicine, Ankara and Hacettepe Universities, Ankara, and Cerrahpasa Faculty of Medicine, Istanbul University, Istanbul, Turkey, between April 2001 and June 2003. RESULTS: There were 2 branches in 19 hearts, 3 branches in 19 hearts, 4 branches in one heart and 5 branches in another. Diameter and length of these vessels are noted. CONCLUSION: Upon examination of the diameters and important variations of the branches of the left coronary artery, the importance of the median artery has been noted. Various names given to this artery in the literature should be replaced with the name "median artery".

[The reliability of percutaneous osteotomy with the Gigli saw technique in the proximal tibia. A cadaveric study].

OBJECTIVES: To evaluate the reliability of percutaneous osteotomy with the use of a Gigli saw in the proximal tibia. METHODS: Forty-two attendants comprising of residents or consultants without any prior experience were assigned to 14 cadaveric models to perform percutaneous osteotomy. The technique was first described by an experienced specialist and then illustrated on a cadaver specimen. Thereafter, the attendants performed osteotomy using a Gigli saw without any help by the instructors. Finally, exploration of the deep and superficial branches of the fibular nerve, posterior tibial nerve, posterior and anterior artery and vein was made with regard to any injury caused during osteotomy. RESULTS: There were ten incisional injuries in three specimens due to erroneous determination of the osteotomy level or incision. A mean of 3.5 cm (range 2.5 to 4.0 cm) incision length was observed in four specimens. No procedure-associated injuries to major nerves and vessels were documented except for those to the cutaneous branch of the superficial peroneal nerve in two specimens, and to the extensor hallucis longus muscle in one specimen. There was no incidence of incomplete osteotomy. CONCLUSION: Despite the lack of any prior experience with the osteotomy method with the Gigli saw on the part of the attendants, the full success in performing osteotomy confirms the reliability of the technique. Moreover, if this method is to be used by experienced surgeons, excellent results can be achieved without any injuries to cutaneous nerves and surrounding muscles.
