Corona Mortis: the Abnormal Obturator Vessels in Filipino Cadavers
ORIGINAL ARTICLE Corona Mortis: the Abnormal Obturator Vessels in Filipino Cadavers Imelda A. Luna Department of Anatomy, College of Medicine, University of the Philippines Manila ABSTRACT Objectives. This is a descriptive study to determine the origin of abnormal obturator arteries, the drainage of abnormal obturator veins, and if any anastomoses exist between these abnormal vessels in Filipino cadavers. Methods. A total of 54 cadaver halves, 50 dissected by UP medical students and 4 by UP Dentistry students were included in this survey. Results. Results showed the abnormal obturator arteries arising from the inferior epigastric arteries in 7 halves (12.96%) and the abnormal communicating veins draining into the inferior epigastric or external iliac veins in 16 (29.62%). There were also arterial anastomoses in 5 (9.25%) with the inferior epigastric artery, and venous anastomoses in 16 (29.62%) with the inferior epigastric or external iliac veins. Bilateral abnormalities were noted in a total 6 cadavers, 3 with both arterial and venous, and the remaining 3 with only venous anastomoses. Conclusion. It is important to be aware of the presence of these abnormalities that if found during surgery, must first be ligated to avoid intraoperative bleeding complications. Key Words: obturator vessels, abnormal, corona mortis INtroDUCTION The main artery to the pelvic region is the internal iliac artery (IIA) with two exceptions: the ovarian/testicular artery arises directly from the aorta and the superior rectal artery from the inferior mesenteric artery (IMA). The internal iliac or hypogastric artery is one of the most variable arterial systems of the human body, its parietal branches, particularly the obturator artery (OBA) accounts for most of its variability. -

The left brachiocephalic vein passes behind the ascending aorta and connects with the right brachio- cephalic vein, and the left renal vein passes behind the abdominal aorta. These two anomalous cases mentioned above have been reported respectively. There have been few reports discussing coexistence of the postaortic left brachiocephalic vein with the postaortic left renal vein. We discuss the anatomical and embryological aspect of this anomaly with reference in the literature. Introduction phalic vein (PALBV) with the postaortic left renal vein (PALRV).

Surgical Anatomy of the Common Iliac Veins During Para-Aortic and Pelvic Lymphadenectomy for Gynecologic Cancer
Original Article J Gynecol Oncol Vol. 25, No. 1:64-69 http://dx.doi.org/10.3802/jgo.2014.25.1.64 pISSN 2005-0380·eISSN 2005-0399 Surgical anatomy of the common iliac veins during para-aortic and pelvic lymphadenectomy for gynecologic cancer Kazuyoshi Kato, Shinichi Tate, Kyoko Nishikimi, Makio Shozu Department of Gynecology, Chiba University School of Medicine, Chiba, Japan See accompanying editorial by Lee on page 1. Objective: Compression of the left common iliac vein between the right common iliac artery and the vertebrae is known to be associated with the occurrence of left iliofemoral deep vein thrombosis (DVT). In this study, we described the variability in vascular anatomy of the common iliac veins and evaluated the relationship between the degree of iliac vein compression and the presence of DVT using the data from surgeries for gynecologic cancer. Methods: The anatomical variations and the degrees of iliac vein compression were determined in 119 patients who underwent systematic para-aortic and pelvic lymphadenectomy during surgery for primary gynecologic cancer. Their medical records were reviewed with respect to patient-, disease-, and surgery-related data. Results: The degrees of common iliac vein compression were classified into three grades: grade A (n=28, 23.5%), with a calculated percentage of 0%-25% compression; grade B (n=47, 39.5%), with a calculated percentage of 26%-50% compression; and grade C (n=44, 37%), with a calculated percentage of more than 50% compression. Seven patients (5.9%) had common iliac veins with anomalous anatomies; three were divided into small caliber vessels, two with a flattened structure, and two had double inferior vena cavae.
