A 5french introducer sheath was advanced into the RCF artery. This survey demonstrates that there is lack of consensus and wide variability in the UK IR community as to the best application of splenic embolisation in the acute traumatic setting; however, this appears to be due to a lack of clear evidence and . Evaluated outcomes included complications, morbidity/mortality rates, and 30-day white blood cell count. Over time, aneurysms may grow. The most common non-variceal cause is peptic ulcer disease, while a rare presentation is peptic ulcer-induced splenic artery pseudoaneurysm (SAP). The increased susceptibility of patients to infections after splenectomy has led to the use of splenic preservation procedures [ 4, 5 ]. Conclusion Primary endoscopic treatment is generally. Splenic ( artery) embolization is an endovascular technique for treatment of splenic and splenic artery pathology as an alternative to splenic artery ligation or splenectomy. Splenic artery embolization has been used as an adjunct to nonsurgical treatment of blunt splenic injuries. After embolization, the subcapsular hematoma of the spleen was reduced, and the hemoglobin level remained normal. It often results in successfully treating the underlying pathology, while maintaining at least partial splenic function. CrossRef View Record in Scopus Google Scholar.

Stent graft placement guided by intravascular ultrasound for subclavian artery dissecting aneurysm The first pitfall to avoid is the failure of catheterization owing to complex anatomy, thus delaying the time for splenectomy. Relative 1. Depending on the aim of the procedure, splenic embolization may be considered an alternative to either splenectomy or ligation of the splenic artery. Management of splenic injury depends on the clinical status of the patient and can include nonoperative management (NOM), splenic artery embolization (SAE), surgery (operative splenic salvage or splenectomy), or a combination of these treatments. When clinically appropriate, these procedures may provide an alternative to open surgery. It has been postulated that splenic infarction after proximal splenic artery embolization does not occur because of the rich network of collateral circulation providing blood flow to the spleen (8, 9). Wire was then directed toward the splenic artery. 189-196. Note the dorsal pancreatic artery (white arrow) and arterial pancreatica magna (open arrow), both of which provide important collateral pathways in the setting of proximal splenic artery embolizations. 2 potential minor complications include post-embolization syndrome and contrast-induced nephrotoxicity, which splenic embolization was first performed in 1973 using autologous clot to treat recurrent gastrointestinal hemorrhage arising from esophageal varices. Transcatheter splenic artery embolization has a major role in the management of traumatic splenic injuries and as an adjunctive procedure in the treatment of thrombocytopenia and portal hypertension.
