“…IMAV AVFs are rare, 33 cases have been reported in the literature for about a half-century [ 1 2 3 4 5 6 7 ]. Among the reported cases, 20 cases were congenital or idiopathic [ 1 2 3 4 5 ] and the rest were usually secondary to previous operation or trauma [ 1 6 7 9 ].…”

“…An arteriovenous fistula (AVF) is an abnormal communication or passageway between an artery and a vein, bypassing the capillary bed. The AVFs can be of congenital or acquired (iatrogenic or traumatic) or idiopathic etiology [ 1 2 3 4 5 6 7 ]. Congenital AVFs occur from undifferentiated embryonic vessels that fail to differentiate into arteries and veins.…”

“…AVFs can occur as a result of blunt or penetrating traumas such as a gunshot or stab wound [ 1 7 ] or idiopathic etiology [ 3 4 5 ]. Although more than 200 cases of AVFs between the hepatic, splenic, and superior mesenteric vessels have been reported in the literature, AVF involving the inferior mesenteric artery and vein (IMAV AVF) is very rare [ 1 2 3 4 5 6 7 ]. We report a case of idiopathic IMAV AVF with ischemic colitis treated with surgical excision.…”

Arteriovenous fistula (AVF) involving the inferior mesenteric artery and vein is very rare with only 33 cases described in the literature and may be of congenital or acquired (iatrogenic or traumatic) or idiopathic etiology. The pathophysiology of AVF that acts as a left-to-right shunt has accounted for clinical signs and symptoms associated with ischemic colitis, portal hypertension, and heart failure. A low incidence and nonspecific clinical signs and symptoms such as abdominal pain, thrill and mass, lower and upper gastrointestinal bleeding make it difficult to establish a diagnosis of inferior mesenteric AVF. Diagnosis of inferior mesenteric AVF is usually established by radiological or intraoperative examination. We report a case of idiopathic inferior mesenteric AVF causing ischemic colitis in a 56-year-old man that was diagnosed preoperatively by multidetector computed tomography and angiography and successfully treated by surgical resection.

We report a very rare case of acute congestive ischaemic colitis of the left colon caused by brutal decompensation of an uncommon arteriovenous malformation (AVM) in the territory of the inferior mesenteric artery (IMA) in a 45-year-old male patient. The patient presented with severe abdominal pain in the left iliac fossa and abundant mucoid stools. The diagnosis of congestive colitis was made by optical colonoscopy but the full diagnosis of the responsible AVM in the IMA territory was made by contrast-enhanced multidetector CT scan combined with colour Doppler ultrasound. Two successive attempts at selective embolization failed to resolve the symptoms and finally, extensive surgery was necessary. The complete imaging findings of the case are presented and the characteristic features of uncommon AVMs and fistulas of the IMA territory are briefly reviewed.

Mesenteric high-flow vascular malformation can cause various clinical symptoms and demand specific therapeutic interventions owing to its peculiar hemodynamics. We report a case of high-flow vascular malformation in the sigmoid mesentery which presented with ischemic colitis. The main trunk of the inferior mesenteric vein was occluded. After partially effective transarterial embolization, transvenous embolization was performed using a microballoon catheter advanced to the venous component of the lesion via the marginal vein. Complete occlusion of the lesion was achieved. Combination of transarterial and transvenous embolization may allow us to apply endovascular treatment to a wider variety of high-flow lesions in the area and possibly avoid the bowel resection.
