Traumatic mesenteric bleeding managed solely with transcatheter embolization.
ABSTRACT We report a rare case of mesenteric bleeding following blunt abdominal trauma successfully treated solely with transcatheter arterial embolization (TAE) of the right colic marginal artery. A 56-year-old woman presented with mesenteric bleeding after being involved in a car accident. Computed tomography (CT) showed a large mesenteric hematoma and hemoperitoneum with no associated major injuries to other organs. There was a pseudoaneurysm with extravasation inside the hematoma. TAE was attempted to control bleeding during the preparation for surgical laparotomy. A superior mesenteric angiogram revealed a right colic marginal artery pseudoaneurysm. After successful TAE with microcoils, the affected colon perfusion was preserved via collateral circulation from the ileocolic artery. No ischemic gastrointestinal complications have occurred, and laparotomy has not been necessary during the 6 months after TAE. In isolated mesenteric injury cases, TAE may be a reasonable alternative to emergency laparotomy.

ABSTRACT: The purpose of our study was to compare the capability of the 320-detector row CT (area-detector CT: ADCT) using the step-and-shoot scan protocol for small abdominal vasculature assessment with that of the 16-detector row CT using the helical scan protocol. Contrast-enhanced abdominal CT for preoperative assessment was administered to 25 patients, 18 of whom, suspected of having lung cancer, underwent ADCT using the step-and-shoot scan protocol, while the remaining 7, suspected of having renal cell carcinoma, underwent 16-MDCT using the helical scan protocol. Two experienced abdominal radiologists independently assessed renal interlobar and arcuate as well as mesenteric marginal (Griffith point) arteries by means of a 5-point visual scoring systems. Kappa analysis was used for evaluation of interobserver agreement. To compare the visualization capability of the two systems, the scores for each of the arteries were compared by using the Mann-Whitney U-test. Overall interobserver agreements for both systems were almost perfect (κ>0.78). Visualization scores for renal interlobar and arcuate, (p<0.0001) and mesenteric marginal (Griffith point) arteries (p<0.05) were significantly higher for ADCT than for 16-detector row CT. ADCT using the step-and-shoot scan protocol for small abdominal vasculature assessment can be considered superior to 16-detector row CT using the helical scan protocol.The Kobe journal of medical sciences 01/2011; 56(4):E154-61.

ABSTRACT: Mesenteric trauma is one of the possible injuries caused by the use of seat belts in case of motor vehicle crash. We report here a rare case of rectal bleeding by rupture of a mesosigmoid haematoma. An emergent laparotomy revealed a mesosigmoid haematoma with a centimetric rectal perforation. The wearing of safety belts added some specific blunt abdominal trauma, which directly depends on lap-and-sash belts. Mesenteric injuries are found out up to 5% of blunt abdominal traumas. "Seat belt mark" leads the surgical team to strongly suspect an intra-abdominal trauma. When "seat belt mark" sign is found, in patients with mild to severe blunt car injuries, CT-scan has to be realised to eliminate intra-abdominal complications, including mesenteric and mesosigmoid ones. In case of proved mesenteric haematoma associated to intestinal bleeding, a surgical treatment must be considered as first choice. Conservative approach remains possible in stable patients but surgical exploration remains necessary in unstable patients with active bleeding.Gastroentérologie Clinique et Biologique 09/2010; 34(8-9):499-501. · 1.14 Impact Factor

ABSTRACT: A 58-year-old man was injured in a traffic accident and hemodynamically unstable on admission. An abdominal computed tomography (CT) with contrast enhancement was performed after fluid resuscitation. Fluid accumulated along the mesentery around the cecum. A pseudoaneurysm was found by angiography in the ileal branch. Transcatheter arterial embolization (TAE) was performed in the branch using microcoils. His hemodynamics stabilized after TAE. In a CT performed after 12 h, free air was suspected and an exploratory laparotomy was performed. No intestinal perforations were found and hemostasis was completed in the injured mesentery. No ischemic findings were obtained in the intestines. TAE is one of the treatments of choice for mesenteric hemorrhage.Emergency Radiology 10/2008; 16(5):403-6.
