The differential diagnosis of acute flank pain includes kidney stones, urinary tract infection, dissecting abdominal aortic aneurysm (AAA), arterial or venous compromise of the kidney, renal abscess, renal carcinoma, and papillary necrosis. This is a report of an unusual cause of renal colic: pyelocalyceal diverticulum. Stasis of urine within a diverticulum promotes both calculus formation and urinary tract infection, either of which can lead to colic. Several radiographic findings may suggest a calyceal diverticulum, including, on plain X-ray, a very peripheral or mobile renal calculus, or on intravenous pyelogram, an early filling-defect and delayed or retained filing of a circular or ovoid mass.

The authors report the case of a rare mesenteric anomaly in a 71-year-old man who presented with a preexisting abdominal aortic aneurysm (AAA) and a progressive history of postprandial abdominal pain and 10-lb weight loss. Aortography revealed a common celiomesenteric trunk, an absent middle colic artery, and a stenotic inferior mesenteric artery. At operation, neural fibers compressing the common celiomesenteric trunk were lysed, the AAA was repaired, and the inferior mesenteric artery was subjected to endarterectomy and then reimplanted. The patient remains well and free of symptoms 1 year after operation. This rare case demonstrates the many different causes of intestinal angina and its surgical relief.

We describe herein a combined laparoscopic and endovascular approach to treat a type II endoleak due to retrograde flow in the patent inferior mesenteric artery (IMA). A 61-year-old gentleman presented with enlarging aneurysm sac confirmed on computed tomography scan evaluation after elective endovascular repair of an infrarenal abdominal aortic aneurysm. A combined laparoscopic and endovascular approach was used. After distal IMA was identified and marked with a clip laparoscopically, on-table angiography showed a proximal left colic branch and persistent flow in the IMA. Therefore, further laparoscopic exploration was performed by dissection along the distal branch. The origin of IMA was then located and subsequently sealed with 2 surgical clips. The completion angiography confirmed the proper position of the surgical clips and absence of endoleak. Our case demonstrated useful role of endovascular techniques in identifying the origin of IMA during laparoscopic approach for treating type II endoleak.

Primary aorto-colic fistula is rarely reported in the literature. Although infrequently encountered, it is an important complication since it is usually fatal unless detected. Primary aorto-colic fistula is a spontaneous rupture of abdominal aortic aneurysm into the lumen of the adjacent colon loop. Here we report a case of primary aorto-colic fistula in a 54-year old male. The fistulated sigmoid colon was repaired by end-to-end anastomosis. Despite inotropic support, the patient died of sepsis and multiorgan failure on the first postoperative day.

Middle mesenteric artery has been described in 1923. We report the observation of a patient with an abdominal aortic aneurysm who had this rare artery arising from the anterior wall of the aneurysmal sac. His inferior mesenteric artery was occluded at its origin from the aorta and the middle and the distal colon was vascularized only by the middle mesenteric artery. Occlusion of this artery would have been necessary before endovascular repair of the aneurysm. We were concerned about the risk of colic ischemia after the occlusion of the middle mesenteric artery, so we abandoned this approach and operated on the patient via a laparotomy. Based on a case report, we here report a literature overview on the repair of abdominal aortic aneurysm in the presence of a middle mesenteric artery.

A 76-year-old woman presented with sudden massive melena, and superior mesenteric arteriography showed an aneurysm in the middle colic artery (MCA). Because she had a history of right hemicolectomy and ligation of the inferior mesenteric artery (IMA) during open abdominal aortic aneurysm repair, embolization of the MCA aneurysm was considered to pose a risk comparable to that of colonic ischemia. A microballoon occlusion test during occlusion of the MCA confirmed retrograde visualization of the IMA branches through the collateral arteries by way of the left internal iliac artery, and embolization was successfully performed using microcoils. No colonic ischemia or aneurysm rupture occurred after embolization.

Aortic aneurysms are very rare in Middle East unlike Europe and America. Therefore, this pathology is very likely to be missed in acute presentation to the Emergency Medicine Department. We present a case of leaking abdominal aortic aneurysm mimicking right ureteric colic, which was missed in the initial assessment.

A 78-year-old man underwent endovascular abdominal aortic aneurysm repair (EVAR) for a true aortic aneurysm. He developed sudden abdominal pain 4 hr after EVAR. Angiography revealed a dissected aneurysm of the middle colic artery (MCA). Despite conservative treatment, follow-up computed tomography revealed an expanded aneurysm of the MCA. We therefore performed coil embolization of the dissected MCA to prevent a rupture of the aneurysm. There has never been a reported case of acute dissection of the MCA immediately after EVAR that was not caused by catheters. In this report, we discuss the possible underlying mechanisms and the optimal therapeutic strategy for this rare complication.
