  • 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.

  • Surgical Anatomy of the Common Iliac Veins During Para-Aortic and Pelvic Lymphadenectomy for Gynecologic Cancer

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.

Chentanez, N. Nateniyom, T. Huanmanop, S. Agthong Department of Anatomy, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok, Thailand [Received: 19 June 2017; Accepted: 31 July 2017] Variations of the arterial and venous system of the abdomen and pelvis have im- portant clinical significance in hepatobiliary surgery, abdominal laparoscopy, and radiological intervention. A case of double inferior vena cava (IVC) with complex interiliac communication and variation of the common hepatic artery (CHA) arising from superior mesenteric artery (SMA) in a 79-year-old male cadaver is presented. Both IVCs ascended on either side of the abdominal aorta. The left-sided IVC crossed anterior to the aorta at the level of the left renal vein. The union of both IVCs was at the level just above the right renal vein. The diameter of right-sided IVC, left-sided IVC and the common IVC were 16.73 mm, 21.57 mm and 28.75 mm, respectively. In the pelvic cavity, the right common iliac vein was formed by a union of right external and internal iliac veins while the formation of left common iliac vein was from the external iliac vein and two internal iliac veins. An interiliac vein ran from right internal iliac vein to left common iliac vein with an additional communicating vein running from the middle of this interiliac vein to the right common iliac vein.

Malignant tumors can compress, adhere or infiltrate the IVC wall causing endothelial damage ache, weight loss and fever. MRI Lumbosacral spine (Fig. 1) with subsequent thrombosis. Retroperitoneal done in an outside center showed a soft tissue signal lymphadenopathy can cause compressive distortion of IVC intensity retroperitoneal mass in aorto-caval region causing venous stasis and turbulent flow. Metastatic compressing IVC- likely lymph nodal mass. retroperitoneal lymphadenopathy from testicular tumor is a rare cause of IVC invasion with resultant IVC thrombosis which can rarely present as backache. High index of suspicion is needed to detect primary testicular tumor in cases of IVC thrombosis, especially in young individuals. A 26 -year old male presented with lower back ache, weight loss and fever. MRI Lumbosacral spine done outside showed a soft tissue signal intensity retroperitoneal mass in aortocaval region compressing IVC. Ultrasound (done outside) revealed mild right sided hydroureteronephrosis secondary to a lobulated heterogeneous mass in inter-aortocaval region encasing right ureter and invading IVC causing thrombosis. Contrast enhanced Computerized axial tomography of abdomen showed a heterogeneously enhancing lobulated mass with multiple internal calcifications, in inter-aortocaval region at L3-4 level invading the IVC causing IVC thrombosis.
