BACKGROUND Drug-eluting stents(DES)are used to treat lower extremity arterial disease.During DES treatment,aneurysmal degeneration occasionally occurs,especially with fluoropolymer-based DES.However,the incidence of pseudoaneurysms after DES placement is rarely reported in the lower extremity region,although there have been several reports on pseudoaneurysm formation after DES placement in the coronary artery region.CASE SUMMARY We report the case of a 64-year-old man who presented with fever and pain in his left hand after dialysis.Bacteremia was diagnosed by blood culture,and after admission,he developed pain on the medial side of the right thigh.A pseudoaneurysm was observed in the right superficial femoral artery(SFA)at the proximal end of a previously placed DES.The bacteremia was thought to have been caused by a pseudoaneurysm of the left superficial brachial artery,and the pseudoaneurysm of the left superficial brachial artery was removed after antibiotic treatment.The pseudoaneurysm of the right SFA rapidly expanded after admission,but the expansion rate was reduced after infection control.Seven months after the first admission,the pseudoaneurysm of the left SFA was re-moved and in situ revascularization performed using a rifampicin-soaked Dacron graft.CONCLUSION Although pseudoaneurysm after DES placement in the lower extremity region is rare,it must be considered in patients with bacteremia.

BACKGROUND Radiation therapy(RT)for nasopharyngeal cancer can cause several complications.In rare cases,an internal carotid artery pseudoaneurysm can occur,which can be fatal.We report the experience of a nasopharyngeal cancer patient who underwent radiation therapy and subsequently developed a fatal pseudoaneurysm of the petrous internal carotid artery.CASE SUMMARY A 39-year-old man was diagnosed with nasopharyngeal cancer 2 years ago(American Joint Committee on Cancer Stage T3N2M0)and received concurrent chemoradiation therapy.He subsequently relapsed and received chemotherapy.One week after the 4th cycle of chemotherapy,he was admitted to the emergency room of our hospital because of massive epistaxis accompanied by a headache.A pseudoaneurysm of the petrous internal carotid artery was confirmed by digital subtraction angiography(DSA).Stent-assisted endovascular coil embolization was performed and complete occlusion was achieved.No pseudoaneurysm was observed on DSA after coil embolization;however,intermittent epistaxis was maintained even after coil embolization.After seven days,a diagnostic laryngoscopy was performed.Massive bleeding occurred after aspiration of the blood clot during the laryngoscopy and the patient died of hypovolemic shock.In this case,epistaxis may have been a sign of pseudoaneurysm;therefore,treatment such as embolization should be performed promptly,and careful management should be undertaken after treatment.CONCLUSION This case highlights a rare,serious complication of RT in nasopharyngeal cancer and how it should be recognized and treated.

BACKGROUND Carotid artery pseudoaneurysm(PSA)is infrequently encountered in clinical settings.Internal carotid artery(ICA)PSA complicated with ischemic stroke is rare.PSAs are typically caused by iatrogenic injury,trauma,or infection.The underlying mechanisms of spontaneous PSA formation are not well characterized.We report a healthy young man who presented with stroke as a complication of spontaneous PSA of the left ICA.CASE SUMMARY A 30-year-old man working as a ceiling decoration worker was hospitalized due to sudden-onset speech disorder and right lower extremity weakness.Medical history was unremarkable.Brain computed tomography revealed ischemic stroke.Digital subtraction angiography showed a left ICA PSA with mild stenosis.The patient was conservatively managed with oral anticoagulation and antiplatelet therapy.He recovered well and was discharged.The patient was in good condition during follow-up.CONCLUSION The occupational history of patient should be taken into consideration while evaluating the etiology of spontaneous ICA PSA in young people with stroke.

BACKGROUND pseudoaneurysms of the hepatic artery or its branches have been reported following abdominal trauma,iatrogenic injury at the time of many operations such as percutaneous transhepatic biliary drainage and cholecystectomy.Hepatic artery pseudoaneurysms after endoscopic retrograde cholangiopancreatography(ERCP)are uncommon and potentially life threatening and should be identified and treated rapidly.CASE SUMMARY We report a case of intra-abdominal hemorrhage secondary to a left hepatic artery pseudoaneurysm resulting from guide wire injury at ERCP.The patient primary diagnosis was acute biliary pancreatitis with cholangitis,he underwent ERCP on the third day of admission.During ERCP,the left intrahepatic bile duct was cannulated three times.Over the sixth day,Contrast enhanced computed tomography scan demonstrated left hepatic lobe contusion and a pseudoaneurysm formation.The patient was successfully treated with the embolization of a small branch of left hepatic artery angiographically.CONCLUSION The common complications of ERCP are pancreatitis,bleeding and perforation.False aneurysms occur as a result of damage to the wall of an artery.As far as we know,it is rare complication has been reported following ERCP.We advise urgent referral for angiographic embolization in this situation to avoid aneurysm rupture.

Purpose: This study aimed to report our 10-year experience with the management of iatrogenic(penetrating trauma) and traumatic(blunt or penetrating trauma) peripheral artery pseudoaneurysms, based on data from a tertiary referral center.Methods: From January 2012 to December 2021, the medical records of consecutive patients with iatrogenic and traumatic peripheral artery pseudoaneurysms were retrospectively reviewed. Patient demographics, clinical features, imaging data, treatment details, and follow-up results were analyzed.Results: Sixty-one consecutive patients were included in this study;48(79%) were men and 13(21%) women,with a mean age of 49.4 ± 13.4 years(range 24–73 years). There were 42 patients(69%) who underwent open surgery, 18(29%) undergoing endovascular embolization or stent implantation, and one(2%) undergoing ultrasound-guided thrombin injection. All patients successfully underwent open or interventional treatment. The median follow-up was 46.8 months(2.5–117.9 months), and the overall reintervention rate was 10%. Of these,one(5%) patient in the interventional treatment group and five(12%) patients in the open surgery group underwent reintervention. The overall complication rate was 8%, with complications occurring only in the open surgery group. No deaths occurred in the peri-operative period. No late complications, such as thrombosis or pseudoaneurysm recurrence, were observed.Conclusion: Peripheral artery pseudoaneurysms arising from iatrogenic or traumatic causes can be effectively treated by both open surgery and interventional procedures in selected patients with acceptable mid-and long-term outcomes.

Left ventricular pseudoaneurysm （LVPA） is a rare clinical entity that could be life-threatening. It could be of congenital and acquired origin. Among the acquired LVPA, post-infarction LVPA constitutes most of the cases. LVPA always occurs after acute myocardial infarction （MI） and develops chronically. Reliable diagnosis and early surgical intervention are vital for the patients＇ recovery. Here we present 7 cases of LVPA in Anzhen Hospital between May 1993 to March 2007, focusing on the evaluation of diagnosis methods and treatment efficiency of LVPA.

We present the case of an 18-year-old female transferred to our center from an outside hospital due to persistent gastrointestinal bleeding. Two weeks prior to her transfer she underwent duodenal omentopexy for a perforated duodenal peptic ulcer. The patient underwent a computed tomography angiogram which identified the source of bleeding as a giant gastroduodenal artery (GDA) pseudoaneurysm. The patient was taken to interventional radiology where successful microcoil embolization was performed. We present this rare case of a giant GDA pseudoaneurysm together with imaging and a review of the medical literature regarding prevalence, etiology and treatment options for visceral arterial aneurysms.

Symptomatic arteriovenous fistula （AVF） with pseudoaneurysm after percutaneous renal biopsy is an uncommon anomaly, occurring from 0.34% to 6.3%.Most of these vascular lesions are of little clinical importance. However, severe bleeding,2 persistent hematuria, or acute urinary retention may occur, requiting treatment. Here we report a case of gross hematuria and acute urinary retention after renal biopsy in a male patient.

BACKGROUND Pancreaticoduodenal artery (PDA) aneurysms are extremely rare. The complicated clinical presentations and high incidence of rupture make it difficult to diagnose and treat. PDA pseudoaneurysms often rupture into the gastrointestinal tract and result in life-threatening gastrointestinal hemorrhage. CASE SUMMARY A 69-year-old man was admitted to our hospital due to right upward abdominal pain. A computed tomography (CT) scan demonstrated acute cholecystitis and cholecystolithiasis. Percutaneous gallbladder drainage was performed subsequently. He was discharged after 3 d and readmitted to hospital for cholecystectomy as arranged 1 mo later. A repeat CT scan revealed an emerging enhancing mass between the pancreatic head and the descending duodenum. Then, he suffered hematochezia and hemorrhagic shock suddenly. Emergency percutaneous angiogram was performed and selective catheterization of the superior mesenteric artery demonstrated a pseudoaneurysm in the inferior PDA. Coil embolization was performed and his clinical condition improved quickly after embolization and blood transfusion. He underwent laparoscopic cholecystectomy and was discharged from hospital after surgery under satisfactory conditions. CONCLUSION PDA pseudoaneurysms are uncommon. Acute haemorrhage is a severe complication of pseudoaneurysm with high mortality which clinicians should pay attention to.
