Abnormal course of left ovarian artery
Nayak SB
International Journal of Anatomical Variations , 2008,
Abstract: Knowledge of variations of blood vessels in and around the renal hilar region is of utmost importance during operative, diagnostic and endovascular procedures in the abdomen. This report describes the variations found in the course of the left ovarian artery. The variation was found during routine dissection in an approximately 60 years old cadaver. The left ovarian artery took its origin from the abdominal aorta at the level of renal artery, passed upwards between the left renal artery and the renal vein and passed down after hooking around the left renal vein. The knowledge of variations of renal and gonadal vessels is important for surgeons doing kidney transplants and for the radiologists doing radiological procedures.

Abstract: The gonadal arteries normally arise from the abdominal aorta. There are reports about the variant origin of these arteries. In the present study, we investigated the origin and course of the gonadal arteries and clinical implications of variant gonadal arteries are discussed. Out of 60 dissections, in 55 cases the gonadal artery was seen arising from abdominal aorta. In the remaining 5 cases, gonadal artery of renal origin was present in 3 cases, two on right and one on left side and of middle suprarenal origin was present in 2 cases on the left side. The present study agreed with the text book account i.e. right testicular artery passing anterior to inferior vena cava in majority of the cases i.e. 27 (90%). In the remaining 3 cases (10%), the right testicular artery was posterior to inferior vena cava. In our study, out of a total of 60 dissections, 57 dissections confirmed to type I pattern (95%). In 2 cases (3.3%) (11 M, 16 M) a type II pattern was seen on the right side. In 1 case (1.7%) (20 M), the left testicular artery arose directly from the aorta and arched over the renal vein giving a type III pattern. Awareness of variations of the testicular arteries such as those presented here becomes important during surgical procedures like varicocele and undescended testes.The variations described here are unique and provide significant information to surgeons dissecting the abdominal cavity.

Abstract: A variant course and branching pattern of the right brachial artery was recorded in a 54-year-old male cadaver during the practical sessions of University College of Medical Sciences, Delhi, India. The right brachial artery divided in the middle third of arm into a medial superficial and lateral deep branch. The superficial medial branch descended anterior to the median nerve and ended by dividing in the cubital fossa into ulnar and radial arteries, whereas the lateral branch descended postero-medial to the median nerve, ending deep to pronator teres as the common interosseous artery. The left brachial artery showed a normal branching pattern by dividing into radial and ulnar arteries in the cubital fossa. The probable origin of such a variation is embryological and familiarity with such variations is imperative as they might affect dynamics of limb function or alter the course of interventional procedures.

Variant origin of left vertebral artery
Singla RK,Sharma T,Sachdeva K
International Journal of Anatomical Variations , 2010,
Abstract: Arterial derangements within the thorax are common, complex and can assume many diverse forms. Accurate knowledge of the normal and variant arterial anatomy of the vertebral artery is important for clinical procedures and vascular radiology. In the present paper, a rare variation of vertebral artery is being reported. The artery on left side, took origin directly from the arch of aorta. Earlier, vertebral artery of aortic arch origin has been described by different authors in the range of 3.1-8.3%. Further its ontogeny and clinical implications are discussed in detail. The present report should be of interest for the clinician with regard to vascular variations in the neck and thoracic region, and may give insight into elucidating the developmental mechanism of angiogenesis.

Abstract: We report a very rare case of high origin of the left testicular artery in a 68-year-old Caucasian male cadaver. The artery originated from the anterolateral aspect of the abdominal aorta, 2 cm cranially to the ipsilateral renal artery. Approximately 1 cm after its origin, it branched off into the inferior suprarenal artery. During its course, the artery crossed anterior to the left renal artery.A knowledge of the variant origin of the testicular artery is important during renal and testicular surgery. The origin and course must be carefully identified in order to preserve normal blood circulation and prevent testicular atrophy. A reduction in gonadal blood flow may lead to varicocele under circumstances. A knowledge of this variant anatomy may be of interest to radiologists and helpful in avoiding diagnostic errors.The testis mainly receives its blood supply from the testicular artery (TA) and drains into the testicular vein [1]. Testicular vessels have an important role in testis thermoregulation [2]. Variations of these arteries and veins have been extensively studied due to their importance in testicular physiology. Moreover, this knowledge has a practical implication during renal and testicular surgery.Anomalies in the origin, course, and number of TAs were observed in 4.7 percent of cases in a study of 150 cadavers [2]. A high origin of the TA from the abdominal aorta, as in our case report, has been noted in only a few instances in the literature [3-6]. We report on such a case and review the relative literature about the macroscopic anatomy, embryology and likely physiological and surgical implications of this variant.We identified a variation in the origin of the TA in a 68-year-old Caucasian male formalin-embalmed cadaver used for educational and research purposes. His cause of death was cardiovascular ischemic disease. Following dissection of the retro-peritoneum and preparation of the abdominal aorta and its branches, an unusual high origin of the left T
Comment on “Abnormal course of left ovarian artery”

International Journal of Anatomical Variations , 2008,
Abstract: To the Editor, International Journal of Anatomical Variations:We have taken interest in the recently published article by Nayak about ovarian artery in your journal [1], and we found the article very informative. We think that such reports could be kept in mind during clinical procedures.In that article, it is emphasized that such kind of variations of ovarian artery are rare than testicular artery variations [1]. Related to this subject, a case report of Acar et al. [2] was referred as a variation in the course of testicular artery, but no other case reports about ovarian artery was included in discussion.In a case report of ours published in 2005 [3], we presented a left ovarian artery variation with a similar course to Nayak’s current report [1]. In our case, after its origin, left ovarian artery coursed between the left renal artery and vein; then made an arch, and different from Nayak’s case it run downward between the anterior-inferior and posterior segmental renal veins. To our opinion, considering similar cases might strengthen the informative value of such reports.

Las arterias gonadales, ramas laterales de la aorta abdominal, usualmente surgen distales a los vasos renales. El conocimiento del origen y trayecto de estas, particularmente sus relaciones con los vasos renales, son importantes para procedimientos quirúrgicos sin complicaciones en la pared posterior del abdomen. La relación de la arteria testicular y los vasos renales fueron estudiados en 80 cadáveres en la Escuela Nacional de Medicina de Calcuta, India y se detectaron tres variaciones raras. Se discuten las posibles implicancias clínicas y explicaciones embriológicas, con la revisión de la literatura de estas variaciones.

International Journal of Anatomical Variations , 2010,
Abstract: A case is reported in which there was a variant origin of thyrolingual trunk from left common carotid artery 2 cm below its bifurcation in the neck. The trunk was running forward and medially and later it was dividing into upper lingual and lower superior thyroid branches. No such artery was seen on right side.
Variant formation and course of the median nerve
Nene AR,Gajendra KS,Sarma MVR
International Journal of Anatomical Variations , 2010,
Abstract: Many formative variations of median nerve are known but this variant formation and course of median nerve is rare. A variant formation of median nerve was noted in the left axilla and arm of a male cadaver, in the form of formation of median nerve behind the third part of axillary artery and its course in arm entirely behind the brachial artery. There may be compression of axillary artery due to the roots of the nerve passing around the artery. Also there may be compression of median nerve between the fork of axillary artery and its branch. This variation may be clinically important because symptoms of median nerve compression arising from similar variations are often confused with more common causes such as radiculopathy and carpal tunnel syndrome.
