Congenital Vitelline Band Causing Intestinal Obstruction in an Adult with a Double Inferior Vena Cava

Introduction. Vitelline artery remnants are rare causes of intra-abdominal bands leading to bowel obstruction. These bands may be associated with Meckels diverticulum. Double inferior vena ca va (IV C) is a rare presentation and is usually identified incidentally. Case Presentation. A sixty-year-old male presented with progressive vomiting for five days and he was clinically diagnosed with intestinal obstruction. Plain X-ray abdomen showed evidence of small bowel obstruction. CT scan of the abdomen revealed dilated small bowel loops with a small out pouching in the distal ileum with a band like structure attached to it. In the CT, left sided patent IV C draining into the left renal vein was identified. Left external iliac vein was in continuity with the left IV C. Left internal iliac vein was draining into the right IV C. Exploratory laparotomy revealed a Meckels diverticulum with a band identified as the vitellin e remnant attached to its apex and inserting at the anterior abdominal wall near the umbilicus. Discussion. Meckels diverticulum with vitellin e bands, although rare, should be borne in mind in adult patients with intestinal obstruction. Identification of this anomaly can be difficult in imaging studies. Presence of double IV C should be mentioned in the imaging findings to prevent possible catastrophic complications during surgery
