Variant Arterial Supply of the Descending Colon by the Coeliac Trunk: A Case Report
2021
Background and Objectives: Knowledge of arterial variations of the intestines is of great importance in visceral surgery and interventional radiology. Materials and Methods: An unusual variation in the blood supply of the descending colon was observed in a Caucasian female body donor. Results: In this case, the left colic artery that regularly derives from the inferior mesenteric artery supplying the descending colon was instead a branch of the common hepatic artery. Conclusions: Here, we describe the very rare case of an aberrant left colic artery arising from the common hepatic artery in a dissection study.
CT-Angiographie versus intraarterielle DSA bei Bauchaortenaneurysmen
1996
PURPOSE To evaluate if CT angiography is able to image all features necessary for the preoperative planning of abdominal aortic aneurysms (accessory renal arteries, stenoses or occlusions of renal and iliac arteries, patency of inferior mesenteric artery). METHODS CT angiography and DSA were performed on 27 patients with abdominal aortic aneurysms. CT angiography was performed using a protocol that covered the abdominal aorta and the pelvic arteries with a single spiral acquisition (contrast dose: 150 ml, collimation: 5 mm, table feed: 7.5 mm/s, increment of reconstruction: 2 mm). Maximum intensity projections (MIP) and axial scans were compared with the results of intraarterial DSA. RESULT…
Trans-limb embolization for treatment of Type 2 endoleak post EVAR: Case report
2021
Introduction Type 2 endoleaks (T2EL) occur after 10%–25% of endovascular abdominal aortic aneurysm repairs and increase the risk factor of endograft repair failure and rupture. Herein we report a case of endovascular treatment of T2EL where we performed a trans-limb embolization. Presentation of case A 63-years-old male previously treated for AAA with endovascular aortic aneurysms repair (EVAR), showed an angio-CT scan followup with a type 2 endoleak fed from inferior mesenteric artery (AMI) with growth of AAA greater of 1 cm than preoperative CT-scan and increase of chronic lumbar pain. Due to high risk of rupture was performed a trans-limb embolization with complete sealing. The 6 months …
Heterogeneity of atherosclerosis in mesenteric arteries and outgrowth remodeling
2009
Abstract Background In patients with acute mesenteric ischemia by occlusive thrombo-embolism, the superior mesenteric artery (SMA) is more affected than the inferior mesenteric artery (IMA). Methods This study investigated postmortem mesenteric arteries from aged subjects (n=21). Four atherosclerotic stages were defined by signs of degeneration and inflammation in sections stained with Elastica-van-Gieson and immunohistology, respectively. Results In females and males, Stages 3 and 4 were found in 62% of the SMA and 24% of the IMA. Lumenal areas based on diameter measurements remained essentially unchanged between Stages 1 and 4. Compared to a Stage 1 reference, remodeling was associated wi…
Endovascular treatment as first choice in chronic intestinal ischemia.
2002
The purpose of this study was to define the place of endovascular treatment in chronic intestinal ischemia (CII). We report here a series of 19 consecutive patients treated with percutaneous angioplasty of the intestinal arteries. We excluded patients with acute ischemia, from the study. From January 1, 1989 to December 31, 2001, 19 patients with symptomatic CII were treated by endovascular techniques. This study group included 11 men and 8 women with a mean age of 59 years (range 30 to 90 years). The clinical presentation included postprandial pain in 16 patients, weight loss in 14 patients, with a mean weight loss of 7.4 kg (range 0 to 30 kg); and gastroparesis in 2 patients. Stenoses wer…
Inferior mesenteric vein as initial landmark for laparoscopic medial to lateral dissection of descending colon - a video vignette
2017
The root of the inferior mesenteric artery is an important area where autonomic nerves are close by, the dissection can be hard and laborious in order to avoid nerve damage; and the separation of mesocolon and retroperitoneum in this area can sometimes be difficult. The inferior mesenteric vein dissection is an alternative option as the first step during medial to lateral approach of laparoscopic left mesocolon mobilisation, as we have shown in this video based on two real cases and two anatomical cadaveric dissection.
