Transcatheter stent implantation is a widely performed procedure for treating native coarctation of the aorta (CoA) in pediatric patients. However, data on mid- to long-term outcomes are limited. The aim of this study was to evaluate the mid-term safety and efficacy of transcatheter CoA stenting based on centrally adjudicated outcomes. This retrospective cohort study included patients aged 15 years or younger undergoing de novo stenting for CoA or recoarctation (reCoA) between 2006 and 2017. Immediate and 5-year outcomes were assessed. Immediate outcomes (procedural and in-hospital) were retrieved from electronic records. Rates of 5-year reCoA, stent fractures, aneurysmal/pseudoaneurysmal formation, and all-cause mortality were mid-term outcomes. The study included 274 patients (64% male and 36% female) with a median (interquartile range) age of 9 (6-12) years. Procedural success was achieved in 251 patients (91.6%). Procedural complications occurred in 4 patients (1.4%), consisting of stent migration in 1 (0.3%) and small non-expanding non-flow-limiting aortic wall injuries in 3 (1.1%). Major vascular access complications were observed in 18 patients (6.6%), acute limb ischemia in 8 (2.9%). In-hospital mortality occurred in 4 patients (1.4%). Five-year cumulative incidence rates of stent fractures, reCoA, and aortic aneurysmal/pseudoaneurysmal formation were 17/100 (17%), 73/154 (48%), and 8/101 (7.92%), respectively. Of 73 reCoAs, 47 were treated with balloon angioplasty, and 15 underwent a second stent implantation. Five-year all-cause mortality occurred in 4/251 (1.6%) patients. Coarctoplasty with stents was safe and effective in our pediatric population during a 5-year follow-up despite a high rate of reCoA.

Blunt chest trauma caused ST-segment elevation myocardial infarction. Diagnosis of intramural hematoma (IMH) using computed tomography was confirmed using electrocardiography, cardiac marker tests, and subsequent coronary angiography. After conservative treatment, the hematoma was completely resolved 1 year later. Differentiating IMH from other arterial injuries is critical for appropriate management.

A man in his 70s presented with a sudden onset stabbing back pain radiating to the chest and pre-syncopal symptoms. He underwent urgent investigations, including a CT angiogram aorta which did not reveal any abnormalities within the thorax, abdomen or pelvis and no cause of symptoms was identified. After being discharged, he re-presented 2 days later with syncopal episodes, abdominal pain and a significant drop in haemoglobin levels. This time, a CT mesenteric angiogram showed two hepatic artery pseudoaneurysms and a large haemoperitoneum. Following a hepatic artery embolisation, a workup showed that the likely cause of the pseudoaneurysms was a rare first presentation of polyarteritis nodosa. This case highlights the importance of considering the possibility of an aneurysmal rupture, especially when common causes of an acute abdomen have been excluded, and not relying on previous negative investigations to exclude pathology, as the outcomes can be detrimental.

AIM
Significant gastrointestinal hemorrhages, resulting from long-term compression of the duodenum by a hepatic pseudoaneurysm (HAPA), is an extremely rare condition. In fact, when the pseudoaneurysm is small in diameter, diagnosis can be particularly challenging. Timely and effective diagnosis and treatment is therefore of great significance, and in this case, endoscopy, combined with intravascular therapy, can provide an effective approach, especially since it removes the need for surgery while yielding favorable outcomes.
CASE SUMMARY
A 75-year-old old man presented to the hospital's emergency department with hematemesis and black stool. Despite conservative treatments such as "acid suppression, fluid resupply, hemostasis and blood transfusion", no significant improvement was noted. Emergency gastroscopy subsequently revealed an ulcer in the duodenal bulb (Figure 1), with an exposed thrombotic head and active bleeding on the surface. In addition, abdominal computed tomography (Figure 2) showed no obvious HAPA manifestations. After unsuccessful endoscopic hemostasis, angiography was performed (Figure 3) and a pseudotumor-like dilatation measuring 5.56 mm in diameter was found at the distal end of the proximal branch vessel of the common hepatic artery. Following spring coil embolization (Figure 4), the patient's condition improved and he was discharged from the hospital, with a follow-up after six months showing no signs of recurrence or complications.
CONCLUSION
Duodenal ulcer hemorrhages due to small hepatic pseudoaneurysms are very rare, with endoscopic intervention being effective for such cases.

BACKGROUND When people in their 60s experiences abdominal pain, vomiting, and unexplained weight loss without a history of abdominal surgery, the usual diagnosis is obstruction caused by a neoplastic mass. Nevertheless, in exceptionally rare cases, these symptoms arise from complications linked to a visceral artery aneurysm. CASE REPORT We present a case of a 60-year-old man with immunodeficiency and Sneddon-Wilkinson disease (a rare subcorneal pustular dermatosis), who developed a pancreaticoduodenal aneurysm of uncertain origin, associated with pancreatic mass, retroperitoneal hematoma, and duodenal obstruction. The treatment approach included transcatheter arterial coil embolization with supportive measures such as parenteral nutrition, a nasogastric tube, octreotide administration, and antiemetics. Despite these interventions, persistence gastrointestinal symptoms prompted an endoscopic ultrasound fine-needle aspiration to rule out malignancy. The biopsy confirmed localized fibro-inflammation. Although he was initially considered for a gastro-jejunal bypass, conservative management effectively improved the pancreatic lesion and duodenal obstruction, leading to discontinuation of parenteral nutrition. The patient was able to resume a regular diet 4 weeks after embolization. CONCLUSIONS Pancreaticoduodenal artery aneurysm is a rare visceral aneurysm with multiple etiologies and potentially fatal consequences. We report an unusual case of a pancreaticoduodenal artery aneurysm associated with pancreatic mass and duodenal obstruction. This diagnosis warrants consideration when an immunodeficient patient presents symptoms of abdominal pain and vomiting. Early endovascular embolization, combined with conservative approaches, effectively alleviated the symptoms in our patient.

Combined Endovascular and Endoscopic Management of a Secondary Aortoesophageal Fistula after Open Surgical Aortic Repair in a Giant Descending Thoracic Aortic Pseudoaneurysm: Case Report and Review of Literature.
Secondary aortoesophageal fistula (AEF) is defined as a communication between the aorta and the esophagus, occurring after aortic disease treatment or esophageal procedures, associating very high mortality rates with treatment and being fatal without it. Several treatment strategies have been described in the literature, combining open surgery or endovascular aortic repair with surgical or endoscopic management of the esophageal lesion. We present the case of a 53-year-old patient with a history of open aortic surgery for a giant descending thoracic aortic pseudoaneurysm complicated with secondary AEF, successfully managed using emergency transiliac TEVAR (thoracic endovascular aortic repair), extensive antibiotic therapy associated with nutritional replenishment, and rehabilitation therapy. Novel endovascular and endoscopic devices have been developed, offering less invasive treatment strategies with improved outcomes, especially for high risk surgical patients. This case highlights the importance of a multidisciplinary approach to personalized medicine to manage such complex situations.

Carotid blowout syndrome (CBS) is a rare yet life-threatening complication that occurs after radiation therapy (RT). This study aimed to determine the incidence of CBS in patients with head and neck cancer (HNC) undergoing contemporary RT and to explore potential discrepancies in the risk of CBS between nasopharyngeal cancer (NPC) and non-NPC patients. A total of 1084 patients with HNC who underwent RT between 2013 and 2023 were included in the study. All patients were under regular follow-ups at the radio-oncology department, and underwent annual contrast-enhanced computed tomography and/or magnetic resonance imaging for cancer recurrence surveillance. Experienced neuroradiologists and vascular neurologists reviewed the recruited patients' images. Patients were further referred to the neurology department for radiation vasculopathy evaluation. The primary outcome of this study was CBS. Patients were categorized into NPC and non-NPC groups and survival analysis was employed to compare the CBS risk between the two groups. A review of the literature on CBS incidence was also conducted. Among the enrolled patients, the incidence of CBS in the HNC, NPC, and non-NPC groups was 0.8%, 0.9%, and 0.7%, respectively. Kaplan-Meier analysis revealed no significant difference between the NPC and non-NPC groups ( = 0.34). Combining the findings for our cohort with those of previous studies revealed that the cumulative incidence of CBS in patients with HNC is 5% (95% CI = 3-7%) after both surgery and RT, 4% (95% CI = 2-6%) after surgery alone, and 5% (95% CI = 3-7%) after RT alone. Our findings indicate a low incidence of CBS in patients with HNC undergoing contemporary RT. Patients with NPC may have a CBS risk close to that of non-NPC patients. However, the low incidence of CBS could be a potentially cause of selection bias and underestimation bias.

Review
This case report and review describes a 31-year-old man with a history of chronic pancreatitis who presented to the hospital with shortness of breath and left-sided chest pain. Three days prior, he underwent mid-splenic artery embolization due to hematemesis attributed to a splenic artery pseudoaneurysm associated with a peripancreatic pseudocyst. Upon this presentation, the patient reported increasing shortness of breath, left-sided pleuritic chest pain, and epigastric and left upper quadrant abdominal pain. Imaging revealed left pleural effusion, splenic infarcts, and adjacent fluid collections. Thoracentesis confirmed an exudative effusion. The pleural effusion was attributed to recent splenic artery embolization, and the patient was discharged on appropriate medications in stable condition on the sixth day of hospitalization. This case underscores the importance of considering embolization-related complications in the differential diagnosis of pleural effusions following such procedures. The etiology, diagnosis, and management of splenic artery aneurysms are discussed in this review.

A visceral artery aneurysm (VAA) is a very rare and lethal vascular anomaly with dramatic consequences. The overall incidence of VAA is 5% of all abdominal artery aneurysms. The involvement of the superior mesenteric artery is even rare (incidence of 3.5-8% of all VAA). The development of superior mesenteric artery pseudoaneurysm following cardiac surgery is scarcely reported in the literature. We report a case of contained rupture of the superior mesenteric artery with no distal flow causing acute mesenteric ischemia (AMI) following double heart valve replacement surgery.
