Current management tends use the step-up approach, with endoscopic collection drainage, followed by percutaneous drainage by an interventional radiologist and video-assisted necrosectomy. We present our experience with a new percutaneous technique of establishing an anastomosis of the pancreatic collection with the closest loop, stomach, duodenum or jejunum that uses balloon dilation and drainage in cases of infection.</div></div><div><h3>Material and methods</h3><div>Between 2009 and 2023 we have applied this technique in 30 patients, aged between 32 and 82 years (mean: 67<!--> <!-->years), 14 with pseudocysts (infected in six cases) and 16 with encapsulated necrosis (all infected). We use dilation balloons of different calibre, to establish the anastomosis between the digestive loop and the collection, as well as different drainages.</div></div><div><h3>Results</h3><div>The intervention had a primary technical success of 93%. In two patients the cystogastrostomy had to be repeated due to initial technical failure; in both cases a good result was achieved. One patient had a severe postintervention haemorrhage (3%) that required embolisation. Length of follow-up has ranged from between three months and 10 years (mean: 4<!--> <!-->years), with no recurrence of the anastomosed collection or cutaneous fistula observed in any case.</div></div><div><h3>Conclusion</h3><div>Percutaneous cystogastrostomy is a technique that allows infected collections to be resolved and pancreatic fistulas to be avoided, with few complications, which can be resolved by interventional vascular radiologists.</div></div>","PeriodicalId":31509,"journal":{"name":"RADIOLOGIA","volume":"67 2","pages":"Pages 147-154"},"PeriodicalIF":1.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141036581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computed tomography angiography (CT angiography) is the imaging technique of choice for diagnostic confirmation, assessment of complications and treatment planning. Doppler ultrasound is initially used in accessible peripheral arteries. Complications with pseudoaneurysms can be serious, and this is especially true in the case of rupture. Therefore, an early diagnosis and the ruling out of other pathologies is essential to guide treatment. The objective of this manuscript is to show how pseudoaneurysms appear in different locations depending on their aetiology.
