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.

BACKGROUND: Splenic artery aneurysm (SAA) is a focal dilation of the splenic artery with varying etiologies including atherosclerosis, arteritis, or trauma. Giant SAAs with a diameter of 10 cm is rare and can lead to severe complications like rupture and fistulas. Therefore, an accurate and timely diagnosis and treatment are important.
METHODS: A 50-year-old male presented with acute epigastric pain and hemorrhagic shock. Considering his symptoms and examination, ultrasound, multi-slice computed tomography and digital subtraction angiography results, a ruptured giant splenic artery aneurysm complicated with an exceptional gastric and transverse colonic fistula was suspected.
METHODS: Ruptured giant splenic artery aneurysm.
METHODS: Left anterolateral thoracotomy to control the severe aortic bleeding just above the diaphragm, aneurysmectomy, splenectomy, and closing the gastric and transverse colon perforations.
RESULTS: Multi-slice computed tomography demonstrated the presence of splenic artery aneurysm in the distal third measuring (10 × 12 cm) in diameter with a true lumen measuring (7 × 3.5 cm) and a large hematoma extending to the greater and lesser gastric curvature. Intraoperatively, a large pulsating mass was detected occupying the epigastrium and the left hypochondrium with severe adhesions with the stomach and transverse colon.
CONCLUSIONS: Giant SAA with a diameter of 10 cm is rare and is associated with severe complications. Therefore, successful treatment of splenic artery aneurysms involves prompt diagnosis, immediate surgical intervention to control bleeding, and tailored approaches like thoracotomy to control the thoracic aorta for better hemodynamic stabilization, aiming to eliminate the aneurysm and reduce complications effectively.

UNASSIGNED: During the routine dissection classes for undergraduate medical students, we encountered a rare anatomical variation concerning the aberrant origin and course of the accessory splenic artery. The splenic artery is one of the direct branches of the coeliac trunk. During its tortuous course, it supplies the pancreas with greater curvature of the stomach and spleen. The accessory splenic artery originating from the main trunk of splenic artery, too, follows the same tortuous course while running through the lesser sac and supplies the posterior part of the spleen via the splenophrenic ligament. The accessory splenic artery is gaining clinical importance during various GI surgeries and some radiological procedures. The unnoticed accessory splenic artery damage may result in tremendous bleeding while performing GI-based surgery or radiological investigation like angiography. In our case report, the accessory splenic artery is an aberrant origin from the initial part of the actual splenic artery. Knowledge regarding the origin, course and termination is of utmost importance to GI surgeons, radiologists, and anatomists.

Splenic artery embolization plays an important role in the management of various medical and surgical conditions that are non-traumatic in etiology, in addition to its well-established and widely discussed role in managing splenic trauma. In nontraumatic emergencies of catastrophic bleeding originating from the spleen or splenic artery, splenic artery embolization can be effective in achieving hemostasis as a definitive management, temporary stabilizing measure, or preoperative optimization technique. In addition to emergency clinical conditions, splenic artery embolization can be performed electively as an alternative to splenectomy for managing patients with hypersplenism. Herein, we report 6 cases of splenic artery embolization performed at our center to highlight its various indications. This article aims to demonstrate the role of splenic artery embolization in different clinical scenarios and the considerations behind the techniques employed through illustrative cases.

BACKGROUND: This study evaluated fetal pancreas size and echogenicity, and splenic artery (SA) waveforms in pregnant women with gestational diabetes mellitus (GDM).
METHODS: This prospective case-control study was performed from October 2022 to November 2023 and included 124 pregnant women (62 with GDM and 62 controls). Pancreatic circumference, pancreatic echogenicity, umbilical artery Doppler measurements (systolic/diastolic ratio [S/D] and pulsatility index [PI]), SA Doppler measurements (S/D, PI, peak systolic velocity [PSV], time-averaged maximum velocity, and pressure gradient [PG] mean and maximum) values were compared between the GDM and control groups.
RESULTS: The mean pancreatic circumference was higher and grade 2/3 echogenicity was more common in the GDM group, while grade 1 echogenicity was more common in the control group (p < 0.001 and p < 0.001, respectively). SA S/D and PI measurements were significantly higher in the GDM group than in the control group (p < 0.001 and p = 0.001, respectively). Moreover, PGmax was significantly higher in the GDM group than in the control group (p = 0.038). Pancreatic circumference was positively correlated with SA PSV (p = 0.004). Additionally, pancreatic circumference was positively correlated with PGmean and PGmax (p = 0.010 and p = 0.016, respectively). The increase in pancreas echogenicity was positively correlated with SA S/D and PI measurements (p = 0.007 and p = 0.002, respectively). PGmax was also positively correlated with increased pancreas echogenicity (p = 0.023).
CONCLUSIONS: This study showed that fetal pancreas size and echogenicity were significantly higher in pregnant women with GDM than in controls. SA Doppler waveforms were consistent with an increase in vascular resistance associated with elevations of both S/D and PI in the GDM group.

UNASSIGNED: Blunt abdominal trauma is one of the most common reasons for emergency department visits, and spleen and splenic vasculature is involved variably in those cases. Splenic artery pseudoaneurysm formation is one complication with potentially devastating consequences. Early detection and management are of paramount importance given its potential fatality. Management includes open repair with or without splenectomy, and endovascular approach. The minimally invasive endovascular treatment offers earlier recovery, preserved splenic function, and positive outcomes. We report a case of delayed presentation of a large splenic artery pseudoaneurysm after blunt abdominal trauma, managed using endovascular intervention.
METHODS: A 45-year-old male presented 10 days after being involved in a pedestrian accident with blunt abdominal trauma resulting in a large splenic artery pseudoaneurysm. After multidisciplinary discussion, the decision was to take him for endovascular treatment. The patient recovered very well and was discharged two days later and followed up in an outpatient setting. Over a year, he became symptom free, and demonstrated radiological finding of shrinking pseudoaneurysm.
UNASSIGNED: Pseudoaneurysms of visceral arteries are repaired regardless of their size per society of vascular surgery guidelines. Larger ones are at higher risk of rupture and are associated with high mortality. When discovered, treatment plans should be readily discussed, and undertaken. In our case, the patient had a 6.5 cm splenic artery pseudoaneurysm, and a multidisciplinary meeting was conducted and concluded that endovascular treatment would be the best modality to start with, with surgical option as a backup in a hybrid room setting.
CONCLUSIONS: Blunt abdominal trauma can present with overt symptoms of internal organ injury; however, some might be missed and need high index of suspicion and therefore further testing and imaging. Splenic artery pseudoaneurysms can expand and rupture in delayed presentation, early detection and management is of paramount importance. Endovascular treatment represents an excellent modality, with minimal invasive nature, faster recovery, and early return to daily activity with preserved splenic function.

BACKGROUND: Splenic artery pseudoaneurysm is a rare complication of recurrent pancreatitis usually presenting as an incidental finding on abdominal computed tomography.
METHODS: We present the case of a 66-year-old north African male with a known history of previous pancreatitis who presented with upper gastrointestinal bleeding along with recurrent epigastric pain for 3 days. Investigations did not reveal any particular pancreatitis etiology. Computed tomography of the abdomen with contrast showed splenic artery pseudoaneurysm along with findings suggestive of acute pancreatitis. Upper and lower endoscopies failed to identify gastrointestinal the bleed source. The patient underwent intervention radiology embolization of the aneurysm sac with multiple coils via right retrograde common femoral artery-celiac access. The patient was discharged with a plan for capsule endoscopy in outpatient setting.
CONCLUSIONS: Splenic artery pseudoaneurysm is a life-threatening complication and carries a high mortality rate if left untreated. Prompt identification through various imaging modalities, followed by urgent intervention, is crucial to avoid adverse outcomes.

This case report aims to elucidate the current practices and efficacy of endovascular repair in managing splenic artery aneurysms (SAAs), particularly focusing on a case of a large, partially ruptured SAA. A 66-year-old female presented with severe abdominal pain and was later diagnosed with a 53mm saccular, degenerative SAA showing signs of partial rupture. The patient underwent successful endovascular repair using a combination of interlocking detachable coils and fibered coils. Despite the initial success, a follow-up CT angiogram revealed residual issues, necessitating additional embolization. The patient recovered well, with subsequent follow-ups indicating complete aneurysm closure and no complications. The successful management of this case aligns with current trends in SAA treatment, emphasizing the shift towards endovascular repair methods. This approach, highlighted in the literature, offers a minimally invasive alternative to open surgery, with lower morbidity and mortality rates. This case underscores the importance of individualized treatment planning and vigilant follow-up, particularly in light of the potential need for secondary interventions. This report contributes to the growing body of evidence supporting endovascular repair as a safe and effective treatment for SAAs, advocating for continued research into long-term outcomes and the development of advanced endovascular technologies.

UNASSIGNED: Splenic artery aneurysms (SAA\'s) pose a rare yet clinically significant challenge, characterized by the weakening and ballooning of the splenic artery, potentially leading to severe complications such as rupture and hemorrhage.
METHODS: A 52-year-old female presenting with biliary colic. Diagnostic imaging revealed a saccular lesion closely associated with gallstones. A multidisciplinary approach guided the decision for surgery due to the size and location of the aneurysm. A bi sub costal laparotomy was performed, after the resection of the aneurysm, an arterial anastomosis with pds 5/0 suture was performed.
UNASSIGNED: SAA\'s treatment modalities are tailored based on aneurysm localization and size. Imaging modalities such as Doppler ultrasound and CT angiography play a crucial role in accurate diagnosis, providing essential information for treatment planning. Treatment options include endovascular embolization, and surgical intervention. Traditionally open surgical techniques, including ligation of the splenic artery, aneurysmectomy, and splenectomy. Surgical treatment, especially for proximal aneurysms, is highlighted, with the presented alternative approach of resection with end-to-end anastomosis, showcasing an alternative surgical technique aimed at reducing the risk of spleen infarction.
CONCLUSIONS: SAA\'s are a rarity that emphasizes the need for early detection and intervention. We are urged to maintain a high index of suspicion, particularly in high-risk individuals. We report an alternative surgical technique that we hope will contributes to the expanding repertoire of approaches, calling for further research to optimize SAA management strategies in the quest for improved patient outcomes.

UNASSIGNED: Cardiopulmonary resuscitation is essential for cardiopulmonary arrest, but complications from chest compressions warrant monitoring. Although rib and sternal fractures are common, abdominal injuries are rare, and splenic injuries are much rarer.
UNASSIGNED: A 74-year-old man was admitted to the emergency room with a hemorrhagic duodenal ulcer. During hospitalization, the patient went into cardiopulmonary arrest due to hemorrhagic shock. Spontaneous circulation returned after 7 min of cardiopulmonary resuscitation. He underwent transcatheter arterial embolization to stop the bleeding from the duodenal ulcer. The next day, a close examination of the patient\'s progressive anemia revealed splenic injury; transcatheter arterial embolization was performed to save his life.
UNASSIGNED: It is important to consider the complication of splenic injury in patients with cardiopulmonary arrest who have undergone appropriate cardiopulmonary resuscitation. A possible mechanism-especially in patients with a full stomach-is the squeezing of the spleen by the diaphragm, abdominal wall, and stomach.
