Endovascular coil embolization for an anomalous splenic artery aneurysm with a splenomesenteric trunk. J Vasc Surg Cases Innov Tech 2022; 8:576-579. [PMID: 36248400 PMCID: PMC9556584 DOI: 10.1016/j.jvscit.2022.07.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 07/06/2022] [Accepted: 07/27/2022] [Indexed: 11/21/2022] Open
Abstract
We present a case of a splenic artery (SA) aneurysm (SAA) that had arisen abnormally from the superior mesenteric artery in a 63-year-old man who underwent successful endovascular treatment. Although SAAs characterized by this anatomic abnormality are rare, in all 46 reported cases, the SAAs were located at the root of the SA and had originated abnormally from the superior mesenteric artery. This location is different from that of orthotopic SAAs, which are mostly located in the distal third of the SA. The differences in hemodynamics due to the anatomic abnormalities might play an important role in the formation of the anomalous SAAs.

[PMID: 29221838 DOI: 10.1016/j.avsg.2017.09.021] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Revised: 06/26/2017] [Accepted: 09/27/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND Aneurysm of splenic artery (SA) which arises from the superior mesenteric artery (SMA) is a very rare condition. The aim of this study was to present our experience with 2 such patients treated by coil embolization. METHODS A 33-year-old man and a 61-year-old woman were incidentally identified with aneurysms of the SA which arose from the SMA. Endovascular therapy of coil embolization was chosen to treat the aneurysm. RESULTS Follow-up computed tomography showed no change in the location of the coils and occlusion of majority of the aneurysm sac. The 2 patients have been doing well during a 26-month and 10-month follow-up period, respectively. CONCLUSIONS Combined with the experience of the previous literature, we think coil embolization can be cost-effective and minimally invasive in selected cases, depending on the morphology and site of the lesion.

Zhang HY, Chai DZ. Endovascular coil embolization for a giant anomalous splenic artery aneurysm. J Vasc Surg Cases 2015; 1:141-143. [PMID: 31724615 PMCID: PMC6849910 DOI: 10.1016/j.jvsc.2015.03.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2014] [Accepted: 03/01/2015] [Indexed: 11/21/2022] Open
Abstract
Splenic arteries arising from superior mesenteric arteries, also known as splenomesenteric trunks, are uncommon entities. Aneurysms in relation to these variant splenic arteries are even rarer. Open surgery, laparoscopic technique, or endovascular management could be chosen. We report a patient with an anomalous splenic arteries aneurysm that was excluded with coil embolization in a minimally invasive endovascular way. A follow-up contrast-enhanced computed tomography angiogram performed 1 year after the procedure showed total exclusion of the aneurysm sac, patency of the superior mesenteric artery, and the patient was in good condition.

Aneurysm resection and vascular reconstruction for true aneurysm at the initial segment of splenic artery. ACTA ACUST UNITED AC 2015; 35:439-444. [PMID: 26072086 DOI: 10.1007/s11596-015-1450-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2014] [Revised: 04/24/2015] [Indexed: 12/24/2022]
Abstract
The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10-14 days after operation. A 1-14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery.

Successful treatment of aberrant splenic artery aneurysm with a combination of coils embolization and covered stents. BMC Surg 2014; 14:62. [PMID: 25176112 PMCID: PMC4167310 DOI: 10.1186/1471-2482-14-62] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2013] [Accepted: 08/22/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Aneurysms of an aberrant splenic artery originating from the superior mesenteric artery (SMA) are extremely rare; however, they are clinically important because possible rupture could be catastrophic. The methods of treatment for this condition include surgical resection, minimally invasive techniques (include laparoscopic technique) and endovascular therapy. The purpose of this study is to evaluate the efficacy of coils embolization combined with covered stents to treat aberrant splenic artery aneurysm (SAA). CASES PRESENTATION We report four consecutive cases of aberrant SAA that the aberrant splenic artery was embolized with coils and the superior mesenteric artery was excluded with a covered stent and an up-to-date review of all previous cases in the field. A follow-up computed tomography performed 6 to 12 months postoperatively showed persistent exclusion with marked shrinkage of the aneurysm sac. CONCLUSIONS The authors believe although early results are promising, further careful follow-up will be needed to determine the long-term clinical efficacy, safety and applicability of this approach.
