ABSTRACT
A common trunk of origin of the right testicular and middle suprarenal arteries with a retrocaval course was observed during the dissection of a male cadaver. The Common trunk (CT) arose from the anterior aspect of the abdominal aorta (AA) at the level of the right renal artery (RRA) and after a short course behind the inferior vena cava (IVC), the CT divided into right testicular and middle suprarenal arteries. The middle suprarenal artery (MSA) passed upwards behind the IVC to the right suprarenal gland. The right testicular artery (RTA) descended posterior to the RRA and anterior to the IVC. It then continued on its normal route distally with the right testicular vein. The awareness of such variations of testicular and middle suprarenal arteries and their unusual origin and course might complicate the interpretation of angiograms and surgical procedures in the posterior abdominal area.
ABSTRACT
Proper knowledge of muscular variations is essential for both anatomists and surgeons. Variations of the flexor carpi ulnaris (FCU) are not very common. We are reporting an unusual case of FCU muscle with two bellies. The two heads (ulnar and humeral) of the muscle continued as two separate bellies and the tendons of which joined each other slightly proximal to the wrist before getting inserted to pisiform bone. Further, detailed literature review of variations of FCU muscle is done and the developmental basis for the variation and its surgical importance are discussed.
El correcto conocimiento de las variaciones musculares es esencial para anatomistas y cirujanos. Variaciones del músculo flexor ulnar del carpo (MFUC) no son muy comunes. Se reporta un caso inusual del MFUC con dos vientres. Las dos cabezas (ulnar y humeral) del músculo continuaron como dos vientres separados. Los tendones se unieron entre sí, ligeramente proximal a la muñeca, antes de llegar a su inserción en el hueso pisiforme. Se hace una detallada revisión de la literatura de las variaciones del MFUC y son discutidas las bases del desarrollo de las variaciones, destacándose además su importancia quirúrgica.
