Lemierre syndrome is a rare complication of oropharyngeal infection that causes septic thrombophlebitis in the internal jugular vein. Since the onset of the COVID-19 pandemic, this condition has been dangerously overlooked and poses an even greater threat when complicated by vascular pathologies. A case is presented where the patient required emergency endovascular exclusion of a right internal carotid artery pseudoaneurysm due to Lemierre syndrome. The treatment included stent graft placement and drainage of a neck abscess, along with appropriate antibiotic treatment during hospitalization. Recognizing this diagnosis requires a high index of suspicion, particularly during the COVID-19 pandemic. The complexity of the disease necessitates extensive multidisciplinary collaboration for effective treatment.

Inferior phrenic artery (IPA) aneurysms are the rarest type of visceral aneurysms. It usually occurs secondary to trauma, surgery, or as a complication of pancreatitis. In addition, it can be a manifestation of underlying systemic pathology such as vasculitis, collagen vascular disorders, sepsis, or segmental arterial mediolysis. It can be associated with hypertension in 43% of cases. The presentation of IPA aneurysm is nonspecific with abdominal pain, melena, hematochezia, and anemia. The ruptured and actively bleeding aneurysm can lead to hemorrhagic shock, and immediate management is required with angiography and endovascular embolization with coil or gel foam or stent etc. Inaccessible locations are reached with surgical intervention, but it is associated with high morbidity and mortality. We here report a rare case of spontaneously ruptured IPA pseudoaneurysm extending from the posterior mediastinum to the subdiaphragmatic area and managed with coil and gel foam embolization.

The aim of this study was to examine the imaging manifestations of post-endoscopic retrograde cholangiopancreatography (ERCP) specific complications by computed tomography to aid in its early and successful diagnosis and timely intervention. Forty-one cases of imaging having post-ERCP were complications were retrospectively collected and the spectrum of complications and their key imaging features and methods to improve their detection were analyzed. The most common complication detected in computed tomography (CT) post-ERCP was the presence of intra-abdominal collections seen in 21 patients (51.2%). Pancreatitis was seen in 20 of 41 patients (48.7%), while bowel perforation was present in 9 patients (21%). Pleural effusion was present in 8 patients (19.5%), liver abscess in 6 patients (14.6%), cholangitis in 4 patients (9.7%), gallbladder perforation in 4 patients (9.7%), displaced common bile duct stent in 3 patients (7.3%), possibility of main pancreatic duct cannulation in 2 patients (4.8%), vascular injury resulting in right hepatic artery pseudoaneurysm in 1 patient (2.4%), thrombosis of portal vein or its branches in 2 patients (4.8%), superior mesenteric vein thrombosis in 1 patient (2.4%), right hepatic vein thrombosis in 1 patient (2.4%), pulmonary thromboembolism in 2 patients (4.8%), duodenal inflammation in 1 patient (2.4%), bowel ileus in 4 patients (9.6%), and bowel obstruction in 1 patient (2.4%). Complications after ERCP can cause significant morbidity and mortality if not diagnosed early and treated appropriately. Familiarity with normal findings post-ERCP and knowledge of the imaging appearance of these complications are vital in the early management of these conditions.

OBJECTIVE
Neurofibromatosis type 1 (NF1) is associated with vascular fragility, which results in aneurysms, arteriovenous fistulas, and dissections. Here, we describe a case of endovascular treatment of a ruptured occipital artery aneurysm that occurred after a craniotomy in a patient with NF1.
CASE PRESENTATION
A 46-year-old man with a history of NF1 underwent a right lateral suboccipital craniotomy to remove a cavernous hemangioma in the right middle cerebellar peduncle. Severe bleeding occurred in the occipital artery during the craniotomy. Due to vessel fragility, coagulation and ligation were not possible, and pressure hemostasis was achieved using cellulose oxide and fibrin glue. On postoperative day 12, the patient developed a sudden swelling on the right side of the neck as well as tracheal compression. Contrast-enhanced CT revealed a ruptured aneurysm in the right occipital artery. Transarterial embolization was performed under general anesthesia the same day. Right external carotid angiography showed an 18-mm-diameter fusiform aneurysm in the occipital artery. The aneurysm ruptured inferiorly to form a large pseudoaneurysm with significant jet flow. An arteriovenous fistula was also observed in a nearby vein. A microcatheter was inserted into the fusiform aneurysm under proximal blood flow control, and embolization was performed using coils and -butyl-2-cyanoacrylate.
CONCLUSION
Compared to surgical repair of ruptured occipital artery aneurysms, endovascular treatment appears to be safe, effective, minimally invasive, and rapid. Ruptured occipital artery aneurysms in NF1 patients can cause neck swelling and airway compression and should be recognized as a potentially lethal condition.

Review
BACKGROUND
Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (PMAIF) is a rare complication of infective endocarditis or aortic valve surgery. Surgical treatment is suggested, but the long-term follow-up of conservative management remains unclear.
CASE PRESENTATION
A 33-year follow-up of a patient who developed PMAIF six years after aortic valve replacement is reported. The patient presented to our center with dyspnea, and the echocardiography revealed an ejection fraction of 20% and a PMAIF measuring 7 × 10 mm. Despite being advised to undergo surgery, the patient declined due to fear of surgical outcomes. Consequently, conservative treatment with close observation but without surgery was initiated. During the 33-year follow-up period, the patient did not experience any adverse health effects.
CONCLUSION
Surgical intervention should be considered whenever the PMAIF is diagnosed. However, in any case that the surgery was not applicable, conservative management might lead to long-term survival, based on this and similar case reports in the literature.

European Journal of Obstetrics,... Jun 2024To describe the management of uterine artery (pseudo)aneurysm, ruptured or unruptured, during pregnancy. (Review)
Review
PURPOSE
To describe the management of uterine artery (pseudo)aneurysm, ruptured or unruptured, during pregnancy.
METHODS
After reporting a case about this rare pathology, a review of the literature was performed. The search was applied to PubMed databases.
RESULTS
A total of eighteen articles met the inclusion criteria. Eighteen patients were reported. Eight (44.4 %) patients didn't have prior medical or surgical history. Fifteen (83.3 %) beneficed interventional radiology method during pregnancy including two cases (13.3 %) with repeated embolization because of recanalization of the (pseudo)aneurysm. Nine patients (50 %) beneficed a planned cesarean between 34 and 39 weeks of gestation. One (15.8 %) patient was diagnosed with fetal death before treatment of the uterine artery (pseudo)aneurysm.
CONCLUSION
The decision to proceed to the treatment of the (pseudo)aneurysm must consider several factors, associated or not with a good fetal vitality and a hemodynamically stable patient. Embolization appears to be the method of choice. Mode of delivery and term remain not clear and contraindication of expulsive efforts in case of a uterine artery (pseudo)aneurysm merit further investigations.

BACKGROUND
Behcet's disease (BD) is a systematic vasculitis that affects vessels with various sizes, presenting as venous thrombosis and arterial pseudoaneurysms. The most severe manifestation in BD is ascending aortic pseudoaneurysm, which is associated with high risks of rupture and mortality.
CASE PRESENTATION
We present a case of ascending aortic pseudoaneurysm in a 50-year-old patient with BD. After preoperative evaluation, coil embolization was successfully performed to treat the pseudoaneurysm, resulting in a satisfactory outcome at the 1-year follow-up.
CONCLUSION
Coil embolization serves as an effective treatment option for ascending aortic pseudoaneurysm in BD when open surgical repair and stent graft placement are unsuitable.

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 pla-cement 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.
