RESUMEN
BACKGROUND: Gastric submucosal arterial dilation resulting from splenic artery occlusion represents an exceedingly rare etiology of acute upper gastrointestinal bleeding (UGIB). Although endoscopy is a widely utilized diagnostic and therapeutic modality for gastrointestinal bleeding, it has limitations in detecting arterial abnormalities. CASE SUMMARY: This report presents a rare case of massive UGIB in a 57-year-old male with a tortuous left inferior phrenic artery accompanied by splenic artery occlusion. "Gastric varices" was identified during the patient's endoscopy one year before hemorrhage. Despite initial hemostasis by endoscopic clipping, the patient experienced massive rebleeding after one month, requiring intervention with transcatheter arterial embolization (TAE) to achieve hemostasis. CONCLUSION: This is the first case to report UGIB due to a tortuous left inferior phrenic artery. This case highlights the limitations of endoscopy in identifying arterial abnormalities and emphasizes the potential of TAE as a viable alternative for the management of arterial bleeding in the gastrointestinal tract.
RESUMEN
Splenic artery aneurysms (SAAs) are a relatively uncommon but potentially life-threatening disease. In recent years, although there have been an increasing number of reports of interventional radiology (IVR) treatment for SAAs, there are still many cases in which surgical intervention is required. In particular, SAAs associated with infective endocarditis (SAAs-IE) are rare, and the treatment strategies and perspectives for SAAs-IE remain controversial. Herein, we report a successful case of laparoscopic splenectomy for SAAs-IE with a literature review.
RESUMEN
AIM: Refractory ascites from portal hypertension can be managed with regular large-volume paracentesis (LVP) or transjugular intrahepatic portosystemic shunt (TIPS). Large-volume paracentesis is clinically unsatisfactory and many patients are ineligible or relatively contraindicated for TIPS or Denver shunt. Proximal splenic artery embolization (PSAE) using coils or plugs reduces but does not completely stop splenic arterial inflow, differing from distal splenic artery embolization techniques. By reducing splenic arterial inflow, splenic vein outflow is also decreased, lowering portal pressure and thus treating refractory ascites. METHODS: In this institutional review board-approved single-center retrospective study, electronic medical records were reviewed to obtain demographics and baseline clinical and laboratory data, paracentesis data before and after PSAE, PSAE procedural details, and follow-up imaging up to 12 months post-PSAE. Mixed-effects models were used for statistical analysis. RESULTS: Ten patients with LVP-dependent ascites meeting inclusion criteria underwent PSAE for refractory ascites from 2017 to 2024. Prior to PSAE, four patients had TIPS, three had liver transplants, and the remaining three were neither TIPS nor transplant candidates. In the month before PSAE, patients averaged 3.8 ± 1.7 paracentesis sessions, draining a total of 20.84 ± 10.39 L of fluid monthly. Post-PSAE, the number of paracentesis sessions decreased to 2.1 ± 2.7, 1.0 ± 1.7, 0.4 ± 1.1, and 0.0 ± 0.0 at 1, 3, 6, and 12 months, respectively (p = 0.03). Corresponding ascitic volume drained decreased to 8.7 ± 10.3, 2.7 ± 6.4, 2.0 ± 5.4, and 0.0 ± 0.0 L (p = 0.01). Over the 12-month follow-up period, 6 of 10 patients became LVP-independent. CONCLUSION: Proximal splenic artery embolization can improve refractory ascites in certain patients with portal hypertension, thus providing safe and effective treatment as an alternative to TIPS.
RESUMEN
We present the case of a 40-year-old female who presented with abdominal pain, hematochezia, and melena for the past week and was diagnosed with a pseudoaneurysm emanating from the mid-splenic artery. The patient was managed with endovascular cyanoacrylate glue embolization, resulting in the complete resolution of an impending catastrophic hemorrhagic shock.
RESUMEN
Pseudoaneurysm of the splenic artery is a rare vascular complication of chronic pancreatitis, with a high mortality rate. Haemorrhage and abdominal pain are the most common manifestations, and so far there are no literature reviews on the rare complication of splenic artery pseudoaneurysm due to chronic pancreatitis. Therefore, we describe a male patient with worsening haemochezia and upper abdominal pain, who had been hospitalized repeatedly for 'pancreatitis' 1 year ago, and relevant investigations confirmed a pseudoaneurysm of the splenic artery, which was successfully treated by transarterial embolization, and a literature review is also presented.
RESUMEN
Major gastrointestinal surgical resections and subsequent reconstruction can occasionally need arterial or venous resection, can encounter variant anatomy, or may lead to injury to vessels. These can lead to arterial and/or venous insufficiency of viscera like the stomach, liver, colon, or spleen. Left unaddressed, these can lead to, partial or total, organ ischemia or necrosis. This can trigger a cascade of systemic clinical complications resulting in significant morbidity or even mortality. The aim of this case series is to highlight the utility of microvascular plastic surgical principles and practices in countering these vascular insufficiencies in emergency situations. Retrospective analysis of consecutive cases from March 2014 to May 2022, where intervention for emergency salvage of viscera was done. Microvascular surgical intervention for the vascular insufficient organ was performed, either by primary repair of vessels, use of interposition vein grafts, or anastomosis to a new source vessel (supercharging/super-drainage). Patients were monitored postoperatively for any signs of necrosis of viscera. Microvascular intervention was done in 21 cases: seven cases of supercharging of the gastric tube following esophagectomy, two cases of stomach salvage following pylorus-preserving pancreatoduodectomy, eight cases of hepatic artery restoration, two cases of splenic artery repair, and one each of colon salvage during coloplasty, etc. We were able to salvage the viscera of 20 cases. Arterial and venous insufficiencies can be predictably and safely reversed by precise microvascular techniques. Potentially, many greater numbers of patients can benefit from a microvascular approach to complex resections, injury, and viscera salvage.
RESUMEN
Aneurysms of the splenic artery are the third most common type of intra-abdominal aneurysms and the most common type of visceral aneurysms. Portal hypertension is a significant risk factor for development of these aneurysms. We report the case of a white, female, 52-year-old patient with multiple splenic artery aneurysms and hypersplenism secondary to portal hypertension and cirrhosis. Abdominal angiotomography identified six splenic aneurysms. In this scenario, an endovascular intervention was scheduled to conduct embolization using controlled release coils and Onyx™ embolization agent. The three largest aneurysms were treated. Control angiographs showed good exclusion of the aneurysms. The endovascular technique therefore proved to be a good choice considering the patient's comorbidities and blood disorders. In this case, the procedure was successful. There were no immediate or long-term complications. The patient recovered well and is in clinical follow-up.
RESUMEN
Splenic artery aneurysm (SAA) is the most common visceral artery aneurysm and can lead to severe outcomes if ruptured. This report presents the case of a 71-year-old female who experienced a sudden and severe gastrointestinal hemorrhage 19 years after undergoing pancreaticoduodenectomy for pancreatic head cancer. The patient arrived at the hospital with signs of shock, and imaging revealed an SAA rupture with associated gastric perforation. Emergency treatment involved endovascular techniques, which stabilized the patient and controlled the bleeding. This case highlights the importance of rapid diagnosis and the effectiveness of endovascular therapy in managing SAA rupture, particularly in patients with complex surgical histories.
RESUMEN
Celiac axis stenosis (CAS) is one of the most prevalent splanchnic arterial pathologies. It seldom results in clinically severe ischemic bowel disease because of the rich collateral circulation from the superior mesenteric artery. Knowledge about the collaterals in celiac artery stenosis guides various interventional procedures. Here, we describe a case of a 19-year-old female with American Association for the Surgery of Trauma (AAST) grade IV splenic injury found to have CAS. Distal splenic artery embolisation was performed via the collateral pathway through the pancreaticoduodenal arcade.
RESUMEN
Endoscopic ultrasound (EUS)-guided vascular interventions were first reported in 2000 in a study that evaluated the utility of EUS in sclerotherapy of esophageal varices. Currently, gastric variceal therapy and portosystemic pressure gradient (PPG) measurements are the most widely utilized applications. Ectopic variceal obliteration, splenic artery embolization, aneurysm/pseudoaneurysm treatment, portal venous sampling, and portosystemic shunt creation using EUS are some of the other emerging interventions. Since the release of the American Gastroenterological Association (AGA)'s commentary in 2023, which primarily endorses EUS-guided gastric variceal therapy and EUS-PPG measurement, several new studies have been published supporting the use of EUS for various vascular conditions. In this review, we present the recent advances in this field, critically appraising new studies and trials.
