Ruptured Gastroduodenal Artery Pseudoaneurysms as a Complication of Pancreatitis.

ABSTRACT: Visceral artery pseudoaneurysms is a known vascular complication of pancreatitis that can lead to life-threatening hemorrhages with a high mortality rate if left untreated. We present a case of ruptured gastroduodenal artery pseudoaneurysm in a 68-year-old male with acute pancreatitis presenting with fatal gastrointestinal and retroperitoneal bleeding that was successfully managed with endovascular coil embolization of the involved vasculature. Patients with hemorrhagic pancreatitis or those presenting with unexplained retroperitoneal or gastrointestinal bleeding in the setting of pancreatitis with an unexplained drop in hematocrit or sudden expansion of pancreatic fluid collection should be screened in a timely manner for pseudoaneurysm using CT angiogram of the abdomen, which is the gold standard imaging modality to identify pseudoaneurysms. Once pseudoaneurysm is diagnosed, it should be treated immediately. Endovascular treatment options are now favored over surgical options in most cases.

Project description:ObjectiveComplications in neuroendovascular therapy for cerebral aneurysm (AN) affect the clinical course of patients. Patient conditions, operating procedures, and operator expertise were highlighted as risk factors for complications. These risk factors often combine and constitute particularly strong risks, resulting in a worsened clinical course. In this study, we performed a multifactorial assessment of complication risks in neuroendovascular therapy.MethodsWe analyzed patient data from the Japanese Registry of NeuroEndovascular Therapy 3, which is a nationwide retrospective cohort study of neuroendovascular procedures conducted between 2010 and 2014. Patients who underwent coil embolization for a ruptured anterior communicating artery (Acom) AN, an internal carotid artery-posterior communicating artery (IC-PC) AN, or basilar artery bifurcation (BA-bif) AN were included in this analysis. Information on 16 explanatory variables and 1 objective variable for each patient was obtained from the dataset as nominal variables. The explanatory variables consisted of patient factors, procedural factors, and an operator factor. The objective variable was whether the following complications occurred: intraprocedural bleeding, postprocedural bleeding, and procedure-related infarction. The specific situations involving multiple risk factors associated with high complication rates were identified using a programmed method. The impact of the absence of a supervising physician was also assessed.ResultsA total of 2971 patients were analyzed. The complication rates for patients with Acom ANs, IC-PC ANs, and BA-bif ANs were 12.9%, 10.2%, and 13.7%, respectively. A total of 15 specific situations were identified as follows: 3 related to an Acom AN, with complication rates ranging from 19.3% to 20.3%; 4 related to an IC-PC AN, with complication rates ranging from 15.6% to 17.9%; and 8 related to a BA-bif AN, with complication rates ranging from 20.6% to 33.3%. In 4 of these situations, the absence of a supervising physician significantly impacted complication rates. For instance, the complication rate for patients with IC-PC AN treated under local anesthesia was 16.0% overall, but it was 23.8% without supervising physicians.ConclusionMultifactorial assessment based on patient, procedural, and operator factors provides more reliable risk estimations and will help improve the clinical course.

Project description:BackgroundThis systematic review and meta-analysis investigated the clinical characteristics of patients with gastroduodenal artery aneurysm (GDA), identified risk factors associated with poor clinical outcomes, and elucidated potential differences between various GDA etiologies.MethodsA systematic literature search was conducted from January 2000 to October 2023 in the PubMed, EMBASE, and Google Scholar databases. The analysis focused on extracting data regarding clinical presentations, diagnostic modalities, and patient outcomes.ResultsThis meta-analysis included data from 224 patients derived from 207 case reports spanning 47 countries over a 23-year period. The majority of patients presented with comorbidity (85.3%) and had a predisposing factor for GDA (71.9%). The diagnostic accuracy of the three most common diagnostic investigations-namely angiography, abdominal computed tomography, and ultrasound-was 100.0%, 86.2%, and 59.6%, respectively. Transarterial embolization (75.0%) and surgery (24.1%) were the two most common therapeutic approaches. Emergent treatment for GDA was necessary in 31.7% of patients. Notably, hemostasis was achieved after the initial treatment attempt in 82.6% of patients. The in-hospital mortality rate was 6.7%, with complications occurring in 16.1% of cases. A higher percentage of patients with a complicated hospital course were subjected to observation management and presented with shock during hospitalization.ConclusionsPatients with GDA often have comorbidities and predisposing factors. Clinical presentations of GDA were found to include abdominal pain, hemorrhage, and obstruction of peripheral structures in the vicinity of the gastroduodenal artery. Splanchnic artery angiography and abdominal computed tomography are recognized as the most accurate tools for diagnosing GDA. Endovascular management is the mainstay treatment approach for most patients and have a high rate of hemostasis success during the initial intervention. Surgical intervention is also a practical treatment. Conservative management with observation management may lead to a complicated hospital course, highlighting the potential benefit of aggressive treatment strategies for GDA. Patients with pancreatitis exhibited more comorbidities, predisposing factors, and a broader spectrum of clinical manifestations compared to those without pancreatitis. However, the in-hospital mortality rate was lower in the pancreatitis group, likely due to the younger age of the patients and the more prominent clinical presentations, which prompted earlier and more extensive diagnostic imaging studies.
