Anatomical variations of the inferior mesenteric artery are extremely uncommon, since the inferior mesenteric artery is regularly diverged at the level of the third lumbar vertebra. We found a rare case in which the inferior mesenteric artery arose from the superior mesenteric artery. The findings were made during a routine dissection of the cadaver of an 82-yr-old Korean woman. This is the tenth report on this anomaly, the second female and the first Korean. The superior mesenteric artery normally arising from abdominal aorta sent the inferior mesenteric artery as the second branch. The longitudinal anastomosis vessels between the superior mesenteric artery and inferior mesenteric artery survived to form the common mesenteric artery. This anatomical variation concerning the common mesenteric artery is of clinical importance, performing procedures containing the superior mesenteric artery.

OBJECTIVETo improve the operative procedure of the left renal vein nutcracker syndrome.

METHODSTwo patients underwent transposition of the left renal vein in the treatment of the left renal vein nutcracker syndrome.

RESULTRenal ischemia, due to clamping of the renal artery, lasted 14 minutes and 13 minutes, respectively. The gross hematuria disappeared 1 day and 4 days respectively after surgery, and microhematuria ceased spontaneously 5 days and 7 days respectively after surgery. Transposition of the left renal vein effectively relieved the symptoms related to the left renal vein nutcracker syndrome. The patients had no recurrence of symptoms following up during 3 months.

CONCLUSIONTransposition of the left renal vein is a safe and effective surgical approach in the treatment of the left renal vein nutcracker syndrome.

We report the findings of a patient with an asymptomatic Arc of Buhler (AOB) aneurysm, which was successfully treated by transcatheter coil embolization. An abdominal CT and angiography revealed an intact pancreaticoduodenal artery arcade (PDAA) and an anomalous communication between the SMA and celiac axis, termed an AOB. An aneurysm was observed at the origin of the AOB and treated with a transcatheter embolization using coils. A follow-up CT imaging confirmed the total occlusion of the aneurysm with a patent PDAA. The successful results of this treatment suggest that the endovascular therapy of an AOB aneurysm with a celiac axis occlusion and an intact PDAA is feasible and safe.

Superior mesenteric artery (SMA) syndrome is a rare condition that results from an extrinsic compression of the third portion of the duodenum, between the SMA and the aorta. The symptoms for the condition consist of abdominal pain and recurrent vomiting, caused by ileus, and can be followed by an electrolyte imbalance and nutrient deficiency. SMA syndrome can follow surgical correction of a spinal deformity, as the aorta migrates forward as the degree of the lumbar lordosis increases, and the retroperitoneal fat tissue decreases, during perioperative abstinence. Any symptoms suggestive of SMA syndrome, after correction of a spinal deformity, should be investigated, as SMA syndrome carries a prolonged hospital stay, with the potential for mortality. An 11 year 10 month old boy, who underwent correction for thoracic kyphoscoliosis, developed postoperative abdominal distension, pain and bilious vomiting. An upper gastrointestinal contrast study revealed SMA syndrome, which required a laparotomy.

OBJECTIVE: To analyze the application of three-dimensional power Doppler sonography (3-DPDS) in evaluation of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in second-trimester fetus. METHODS: Three-dimensional volume probe was used to collect the 3-DPDS blood flow images in 50 normal fetuses of 22-24 weeks and 50 fetuses of 30-32 weeks, respectively. The characteristics of three-dimensional ultrasound were analyzed. The clinical and imaging data of 4 fetuses of 26-32 weeks with midgut volvulus were analyzed retrospectively. RESULTS: The display rates of SMA and SMV were 93%in normal group by 3-DPDS and those in volvulus group were 4/4 and 3/4, respectively. The SMV trunk was parallel to and on the right side of the SMA in the normal group, while 3 cases in volvulus group showed the characteristic relationship of SMV swirling around SMA. CONCLUSIONS 3-DPDS can be used to observe the spatial relationship of SMA and SMV visually in fetus during the second trimester and is of value to diagnose and predict the outcome of midgut volvulus.
