“…Two studies report that color Doppler ultrasonography was useful in diagnosing duodenal varices and for visualizing fi ne venous fl ows in the thickened duodenal wall. 17,18 These are the only two reports of color Doppler ultrasonography on duodenal varices. Duodenal varices are formed by the developed collateral veins originating from the portal vein trunk or from the superior mesenteric vein, both of which drain into the inferior vena cava.…”

Efficacy of color Doppler ultrasonography for the diagnosis of duodenal varices successfully treated with percutaneous transhepatic obliteration

We treated a 74-year-old woman who complained of tarry stool. Neither endoscopic examination of the upper gastrointestinal tract nor colonoscopy revealed any finding indicative of bleeding, and (99m)Tc-HSA-D pool scintigraphic imaging showed no accumulation of blood in the digestive tract. Small tortuous collateral veins were observed on computed tomography (CT) in the distal third portion of the duodenum. Color Doppler ultrasonography obtained color flow images of varices in the distal third portion of the duodenum indicating turbulent flow, and color flow imaging showed the outflow vessel from duodenal varices. Duodenoscopy revealed tortuous varices, with erosions and blue in appearance, in the same area. Percutaneous transhepatic portography was carried out 18 days after the treatment of ascites, and hepatofugal blood flow was confirmed in the pancreatic duodenal vein originating near the junction between the splenic and inferior mesenteric veins with the passage of contrast medium into the duodenal varices, which drained into the left ovarian vein. We performed selective catheterization into the afferent vein of the varices, and injected 8 ml of a 5% solution of ethanolamine oleate containing iopamidol. Microcoil embolization using steel coils was added because the therapeutic effect resulting after the relatively rapid washout of sclerosant was insufficient. CT and color Doppler ultrasonography showed absence of blood flow in the varices 1 week after the therapy. This patient has had no episodes of rebleeding in the 24 months after therapy. Color Doppler ultrasonography was useful in diagnosing this case of duodenal varices and in evaluating therapeutic effect.

“…The development of color Doppler ultrasonography enables us to detect small amounts of blood flow [27], as well as to evaluate the portal venous system; however, few reports have described color Doppler findings of gastrointestinal varices [28][29][30]. Color Doppler ultrasonography has advantages over other techniques in that it is a simple non-invasive method and can be used to calculate the blood flow velocity of gastrointestinal varices.…”

A 52-year-old asymptomatic female was admitted to our hospital in January 2008 with enlarged esophageal varices due to alcoholic liver cirrhosis. Color Doppler ultrasonographic examination showed images of vessels on the small intestinal wall around the umbilical area and the anterior wall of the bladder. Images of the vessels were obtained for the small intestinal wall and the anterior wall of the bladder with computed tomography. Percutaneous transhepatic portography was performed, and hepatofugal blood flow was observed in the inferior epigastric vein connected to the superior mesenteric vein and the contrast medium passed into the small intestinal varices and the vesical varices, which drained into the right ovarian vein. Percutaneous transhepatic obliteration was then successfully performed via the afferent veins of the small intestinal varices and vesical varices. One week after the treatment, color Doppler ultrasonography showed a remarkable decrease in blood flow in the varices.

“…Color Doppler imaging has also been used to evaluate gastro-intestinal varices [12]. It may be useful for stratifying bleeding risk in gastro-esophageal varices by demonstrating reversal of flow in the left gastric vein, but is unproven in colonic varices.…”

Ectopic varices (those outside of the gastro-esophageal region) are occasionally found on endoscopy in patients with portal hypertension; however they account for a small minority of all variceal bleeds. Cases of isolated cecal varices are quite rare and, when described, often present with acute hemorrhage or evidence of occult bleeding. We present the case of a 29-year-old male with a history of idiopathic portal vein thrombosis and known esophageal varices, who presented for evaluation of abdominal pain. Cecal varices were found on endoscopy, without evidence of bleeding and without varices in the remainder of the colon or rectum. Endoscopic ultrasound and computed tomography were useful in confirming the diagnosis and natural history of these unusual varices.
