BACKGROUND
Following the rupture of a coronary artery, a patient's condition usually deteriorates rapidly due to cardiac tamponade. A pseudoaneurysm due to a coronary artery rupture is rare; however, when a spontaneous coronary artery pseudoaneurysm occurs without tamponade, it creates a fistula in the right ventricle, often requiring surgical repair.
CASE PRESENTATION
This report describes the case of a 68-year-old man who presented with chest discomfort after a 12-day course of antibiotic treatment for bacteremia. Following coronary angiography, echocardiography, and enhanced computed tomography, he was diagnosed with a right coronary artery pseudoaneurysm accompanied with perforation of the right ventricle. Severe adhesions were observed during emergency surgery surrounding the entire heart. The patient presented with risk factors for coronary artery disease, including hypertension and smoking history. His coronary artery was severely calcified due to end-stage renal failure requiring dialysis; thus, a covered stent could not fit inside the arterial lumen. Consequently, coronary artery bypass grafting to the right coronary artery and right ventricle repair were performed. Unfortunately, the patient died postoperatively due to sepsis from intestinal translocation. This rare development was hypothesized to be an incidental result of the combination of severe post-inflammatory adhesions, extensive coronary artery calcification, and rupture of the calcification crevices.
CONCLUSIONS
In the case of a severe post-inflammatory response, shock without cardiac tamponade may require further scrutiny by assuming the possibility of inward rupture. For patients in poor condition, two-stage surgical treatment might be considered after stabilization with a covered stent.

Despite advances in diagnostic imaging and interventional techniques, pancreatic pseudoaneurysms remain a life-threatening complication of pancreatitis. Presentation varies among patients and may include intra-abdominal, retroperitoneal, or gastrointestinal bleeding and bleeding into the pancreatic or common bile duct. We present a unique case of a 74-year-old man with a history of heavy alcohol consumption who presented with a haematoma surrounding the caudate lobe of the liver. Initially, alcoholic cirrhosis and a ruptured hepatocellular carcinoma were suspected. Therefore, transarterial embolization (TAE) of the caudate branch of the hepatic artery was performed. However, 3 months later, the patient experienced abdominal pain with a lesser sac haematoma and a seemingly interconnected pancreatic cyst. One month later, a pseudoaneurysm appeared in the pancreatic cyst. TAE was successfully performed for the pseudoaneurysm, and the patient showed no signs of recurrence during the 1-year follow-up.

Massive bleeding due to rupture of hypogastric artery pseudoaneurysm is an exceptional complication of colorectal anastomotic leakage. A 41-year-old woman with history of rectal cancer surgery, who debuted with massive rectorrhagia and hypovolemic shock due to rupture of a hypogastric artery pseudoaneurysm as a late complication of a colorectal anastomosis leak. The ruptured hypogastric artery pseudoaneurysm should be taken into account in the differential diagnosis of patients with massive rectorrhagia and history of colorectal anastomosis leak. Endovascular embolization is considered the first-line treatment.

belongs to genus. It is a common gram-negative, facultative anaerobic, rod-shaped organism. It causes a variety of nosocomial infections including urinary tract infection, pneumonia, wound infection, osteomyelitis and endocarditis. Over time complex (ECC) has developed to be resistant to antibiotics including carbapenem. It has been rarely reported to cause gas gangrene and never been reported to cause pseudoaneurysm (PA) of transplant renal artery. We report and share our experience with this rare case of gas forming and muti-drug resistant ECC which led to mycotic PA of transplant renal artery, complicated by bleeding and infected hematoma and which resulted in graft nephrectomy.

Neoaortic pseudoaneurysm after previous surgery is rare and life-threatening. We present a case of a 6th redo surgery in a 23-year-old male patient with a history of hypoplastic left heart syndrome presenting with transsternal penetration of aortic pseudoaneurysm. The previously implanted Dacron prosthesis showed semicircular dehiscence. It was exchanged by a Vascutek prosthesis during circulatory arrest and selective antegrade cerebral perfusion. Control imaging at 1 year after surgery was unobtrusive. Three years after surgery, the patient is alive and doing well.

This case report delineates the clinical trajectory and management strategies of a 59-year-old Hispanic male diagnosed with a left ventricular pseudoaneurysm (LVPA) following a delayed presentation of ST-segment elevation myocardial infarction (STEMI), for which reperfusion treatment was not administered. Initially, an echocardiogram demonstrated an extensive anterolateral myocardial infarction, severe left ventricular systolic dysfunction, and an early-stage left ventricular apical aneurysm with thrombus, leading to the initiation of warfarin. Metabolic myocardial perfusion imaging via positron emission tomography indicated a substantial myocardial scar without viability, guiding the decision against revascularization. Post discharge, the patient, equipped with a wearable cardioverter defibrillator for sudden cardiac death prevention, experienced symptomatic ventricular tachycardia, which was resolved with defibrillator shocks. Subsequent imaging revealed an acute LVPA adjacent to the existing left ventricular aneurysm. Given the high surgical risk, conservative management was elected, resulting in thrombosis and closure of the pseudoaneurysm after two weeks. The patient eventually transitioned to home hospice, surviving an additional five months. This report underscores the complexities and therapeutic dilemmas in managing post-MI LVPA patients who are ineligible for surgical intervention.

We present the case of a 55-year-old male with a pseudoaneurysm in the right coronary sinus of Valsalva. He was found to have a complete heart block in the context of large-vessel vasculitis involving the aortic root and basal interventricular septum. This case demonstrates the importance of generating a thorough differential diagnosis of complete heart block and using multimodality imaging to pursue the investigations for aortitis when a septal recess near the aortic root is detected. Considering to proceed to a surgical intervention earlier in the progression of the disease should also be part of the management.

BACKGROUND
Pedicle screw instrument surgeries can result in the development of aortic pseudoaneurysm, which is a rare yet potentially severe complication; therefore, the purpose of this work is to describe the case of pseudoaneurysm of the thoracic aorta caused by the severe migration of a pedicle screw after surgery.
CASE PRESENTATION
We herein report a patient who underwent endovascular repair for the pseudoaneurysm of the descending thoracic aorta following thoracic vertebral fixation surgery. A 28-80 mm covered stent was initially inserted through the right femoral artery, and intraoperative aortography revealed a minor extravasation of contrast material. Subsequently, an additional 28-140 mm covered stent was implanted. The patient recovered well during the 8-year follow-up period.
CONCLUSIONS
Vascular complications resulting from spinal surgery are severe and rare, necessitating early diagnosis and intervention.

INTRODUCTION
Cystic artery pseudoaneurysm rupture presents a rare yet potentially fatal aetiology for upper gastrointestinal (GI) bleed. While uncommon, its incidence has been rising with increased hepatobiliary surgical interventions, predominantly attributed to iatrogenic injury and rarely secondary to acute cholecystitis. Clinical manifestations typically include epigastric pain, upper GI haemorrhage, and obstructive jaundice. Due to its rarity, it is often excluded from initial differential diagnoses.
CASE REPORT
This is an unusual case of a 54-year-old male who presented with acute cholecystitis complicated by haemobilia and Mirizzi-like obstruction, in the setting of cystic artery pseudoaneurysm rupture. Initially, urgent transcatheter angiographic embolization of the cystic artery was performed to achieve hemodynamic stability. However, a triphasic computed tomography (CT) scan revealed the first attempt was unsuccessful, necessitating a second embolization. Subsequent imaging confirmed satisfactory embolization; however, a small area of liver necrosis was observed adjacent to the gallbladder. The patient was stable at discharge from the hospital and had an uncomplicated interval cholecystectomy.
DISCUSSION
This case highlights the complexity and challenges associated with diagnosing and managing cystic artery pseudoaneurysm rupture. Diagnosis often relies on arterial phase contrast-enhanced CT scan. While no guideline currently exist, management typically involves achieving hemodynamic stability through Transcatheter angiographic embolization, followed by interval cholecystectomy.
CONCLUSION
Early recognition and intervention are crucial in managing cystic artery pseudoaneurysm rupture to prevent life-threatening haemorrhagic shock. Clinicians need to consider this rare condition in patients with upper GI bleeding and abnormal liver function tests.

UNLABELLED
Bronchial artery embolization (BAE) is a procedure that aims to control bleeding from bronchial arteries in massive and chronic haemoptysis. It is considered to be a life-saving measure in severe life-threatening haemoptysis. Although it is minimally invasive and has a high success rate, it still carries a list of complications. These include post-embolisation syndrome, chest pain, back pain, dysphagia, vascular injury at the site of the embolisation leading to dissection, perforation, pseudoaneurysm and, very rarely, embolic infarction to non-target vessels. Stroke is one of the rare complications post BAE, and it can be severe and fatal. Few cases of stroke post BAE have been reported in the literature, and they were mainly due to posterior cerebral circulation infarction. Here, we report a case of a stroke post BAE due to massive middle cerebral artery (MCA) infarction and to our knowledge it seems to be the first reported case of MCA infarction post BAE. The discussion will cover the possible mechanisms of embolic passage, the outcome of the case including rehabilitation perspectives and the learning points. These will also highlight the importance of early recognition, which can save patients from a disabling stroke in the future.
LEARNING POINTS
Bronchial artery embolisation (BAE) carries a high risk of significant complications such as transverse myelitis, bronchial infraction, ischaemic colitis and stroke. While stroke remains one of the rarest complication post BAE, it may be under-reported or unrecognised.Close monitoring in post-BAE patients for any abnormal neurological signs that warrant urgent brain imaging, and early recognition can save patients from a disabling stroke by having the appropriate hyperactive stroke management plan including mechanical thrombectomy.
