Pseudoaneurysms of the neck are seldom, and those caused by neck infections especially parapharyngeal abscess are even rarer. However, it is life-threatening and may bring sudden death due to the obstruction of airway and the pseudoaneurysms rupture. We analyzed the clinical features, diagnosis and treatment of the disease through a case summary and literature review in order to guide clinical diagnosis and treatment of pseudoaneurysms. The patient, whom we presented was an 87-year-old male and admitted in emergency of our hospital with the chief complaint of neck swelling for 7 days and shortness of breath for 2 days. Cervical ultrasound examination showed that there was an liquid dark area next to the left common carotid artery which was approximately 8.0 cm × 5.0 cm, consideration of formation of left carotid artery pseudoaneurysm, and the liquid dark area which was visible on the right considered of pseudoaneurysm or infection. Angiography of neck showed a clustered high-density shadow around the bifurcation of the left carotid artery, with an overall range of approximately 65 mm × 52 mm × 72 mm, the pseudoaneurysms for sure, while on the right side of the lesion, mixed low density shadows with air could be seen, the parapharyngeal abscess for sure.Then he was diagnosed as the pseudoaneurysm of left internal carotid artery which was caused by parapharyngeal abscess. After tracheal intubation and anti-infection treatment, the patient died due to hemorrhagic shock of the ruptured of the pseudoaneurysm. Morever we performed literature search on PubMed, Wanfang database and CNKI with keywords of "neck pseudoaneurysm, neck infection, parapharyngeal abscess" and enrolled 10 cases. Then we summarized the clinical characteristics and treatment. We analyzed and summarized the 10 case reports, in which the number of male was 7. Among them, there were 4 pediatric, and 6 adults were enrolled overall. Most of the symptoms were neck swelling, and the diseased blood vessel was mainly the right internal carotid artery which accounted for half overall. All the patients underwent surgical intervention, and recovered well. So we draw the conclusion that the clinical incidence of cervical pseudoaneurysms is low and can be caused by a variety of factors, especially caused by infectious factors. When a patient has a progressive pulsating mass in the neck, the preliminary diagnosis should be made by ultrasound as soon as possible, and the aortic enhancement CT should be used to further confirm.For a patient with cervical pseudo-aneurysms caused by parapharyngeal infections, he should take operation timely combined with antibiotic treatment in time.

Dorsalis pedis artery (DPA) aneurysms are very rare and fewer than 60 cases have been reported in the literature. Most affected patients present with false aneurysms after orthopedic surgery or trauma. Here we report an unusual case of a giant DPA pseudoaneurysm after cannulation for arterial line placement in a patient newly diagnosed with systemic lupus erythematosus (SLE). A diagnostic delay resulted in necrosis of the overlying skin. Excision of the pseudoaneurysm, ligation of the DPA, and debridement of the foot dorsum were performed, followed by a second flap coverage surgery. Although a DPA false aneurysm is rare after arterial line removal, it can cause the serious complications of skin necrosis, rupture and toe necrosis. Arterial puncture sites should be carefully monitored, especially in patients with SLE or other vasculitis.

Behçet’s disease (BD) is a multisystemic, chronic autoimmune inflammatory vasculitic disease with an unknown etiology. Although the literature reports that vascular involvement occurs in 7% to 38% of all BD cases, the arteries are rarely involved; however, arterial involvement is usually associated with significant mortality and morbidity. We report the case of a young female patient who presented to the emergency department with severe abdominal pain and a history of weight loss. The patient was evaluated using computed tomography angiography, which revealed a ruptured suprarenal aortic pseudoaneurysm with occlusion of both the superior mesenteric and celiac arteries. Urgent surgery was performed with aortic repair with an interposition graft and superior mesenteric artery embolectomy. The patient’s clinical history and radiological imaging findings were strongly suggestive of the diagnosis of BD with vascular involvement.

PURPOSE: Pseudoaneurysms after percutaneous vascular access are common and potentially fatal if left untreated. The aim of this study was to determine the incidence and risk factors associated with access site pseudoaneurysms after endovascular intervention for peripheral arterial disease (PAD) under a routine postintervention ultrasound (US) surveillance protocol. METHODS: A total of 254 PAD interventions were performed in a single center between January 2015 and November 2016, and puncture site duplex US surveillance was routinely performed within 48 hours of the procedure. Clinical, procedural and follow-up US data were analyzed. RESULTS: The overall incidence of pseudoaneurysm was 2.75% (6 cases in the femoral artery and 1 in the brachial artery). There was no difference between retrograde and antegrade approach, but there was a higher rate of pseudoaneurysm formation after manual compression compared to arterial closure device (ACD) use (4.3% vs. 0.87%). Manual compression was more commonly used for antegrade punctures (79.0%) and ACD for retrograde punctures (67.7%). Calcification was more frequently found in antegrade approach cases (46.8% vs. 16.9% for retrograde cases) and manual compression was preferred in its presence. All pseudoaneurysms were treated successfully at the time of diagnosis by US-guided compression repair and there were no cases of rupture. CONCLUSION: Pseudoaneurysm rates after therapeutic endovascular intervention for PAD were comparable to other cardiologic or interventional radiologic procedures despite the higher possibility of having a diseased access vessel. Routine US surveillance of access sites allowed for early diagnosis and noninvasive treatment of pseudoaneurysms, preventing potentially fatal complications.

Aneurysm and pseudoaneurysm of the dorsalis pedis artery (DPA) are rare vascular entities. Pseudoaneurysms of the DPA are commonly due to blunt trauma, sharp penetrating injury, fracture, or iatrogenic injury. Herein, we report the case of a patient with a rare iatrogenic pseudoaneurysm that occurred after blood sampling. The diagnosis was suspected based on palpitation of a pulsatile mass on the dorsal foot and confirmed by color Doppler ultrasound and computed tomography angiography. Surgical treatment was successfully performed by reconstruction with an autologous venous graft. The patient recovered well, with no ischemic complications.

Pseudoaneurysms of the cystic artery and cholecystoduodenal fistula formation are rare complications of cholecystitis and either may result from an inflammatory process in the abdomen. A 68-year-old man admitted with acute cholecystitis subsequently developed massive upper gastrointestinal (GI) bleeding. Abdominal computed tomography showed acute calculous cholecystitis and hemobilia secondary to bleeding from the cystic artery. Angiography suggested a ruptured pseudoaneurysm of the cystic artery. Upper GI endoscopy showed a deep active ulcer with an opening that was suspected to be that of a fistula at the duodenal bulb. The patient was managed successfully with multimodality treatment that included embolization followed by elective laparoscopic cholecystectomy. Presently, there is no clear consensus regarding the clinical management of this disease. We have been able to confirm various clinical features, diagnoses, and treatments of this disease through a literature review. A multidisciplinary approach through interagency/interdepartmental collaboration is necessary for better management of this disease.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a well-established procedure for the diagnosis of pancreatobiliary disease. Serious complications such as perforation, pancreatitis, hemorrhage, and sepsis are rarely reported. To our knowledge, delayed hemorrhage after EUS-FNA is very rare and hemorrhage from iatrogenic pseudoaneurysm has yet to be reported. We report a case of delayed hemorrhage from gastroduodenal artery pseudoaneurysm, which developed after EUS-FNA of a solid pancreatic lesion. A 68-year-old man presented with tarry stool 10 days after EUS-FNA of a 1.5 cm-sized pancreatic head mass. Abdominal computed tomography showed a 2-cm-sized intensely enhancing round lesion near pancreatic head. EUS-FNA was negative for malignancy. The patient refused admission for further evaluation. Twelve days later, he reported to the emergency room with persistent tarry stool. Angiography showed a gastroduodenal artery pseudoaneurysm. Subsequent coil embolization resulted in successful hemostasis. The patient underwent pylorus-preserving pancreaticoduodenectomy and was diagnosed with stage IIB pancreatic cancer.

Arthroscopic synovectomy is a widely-used method to treat septic knee arthritis. To date, many authors have reported minimal complications related to arthroscopic treatment, especially vascular injuries. A three-dimensional computed tomography angiography revealed a pseudoaneurysm that arise from the popliteal artery near the arthroscopic site in septic arthritis patients with atherosclerosis and neurofibromatosis. A careful arthroscopic procedure via the posteromedial or posterolateral portal is recommended for the prevention of this complication. We, therefore, recommend close observation after arthroscopic procedure, despite the occurrence of complications; nonetheless, early diagnosis and treatment are important. We report a case of pseudoaneurysm of the popliteal artery with a complicating arthroscopic synovectomy in septic arthritis with literature review.

We report a rare case of a patient with Moyamoya syndrome who presented with intracerebral hemorrhage resulting from rupture of a middle meningeal artery pseudoaneurysm. This 38-year-old woman was unconscious and hemiplegic when she was admitted to our hospital. The patient had mental retardation as a result of tuberculous meningitis infection at the age of one year. On radiologic examination, she had intracerebral hemorrhage in the right temporo-parietal lobe and an aneurysm in the middle meningeal artery with right internal carotid artery occlusion. The patient underwent surgical treatment for the hemorrhage and aneurysm. The radiologic data, intraoperative findings, and pathology were consistent with a diagnosis of pseudoaneurysm. In the current report, we describe a rare case of a patient with a history of tuberculous meningitis who developed Moyamoya syndrome and pseudoaneurysm, which resulted in a ruptured middle meningeal artery pseudoaneurysm and brain hemorrhage.

A 30-year-old woman experienced severe abdominal pain 8 days after vaginal delivery. The patient was diagnosed with hemoperitoneum due to rupture of the left uterine artery pseudoaneurysm, which was confirmed via ultrasound with color Doppler and computed tomography scans. This patient was treated with bilateral uterine artery embolization to maintain fertility. A uterine artery pseudoaneurysm that causes delayed postpartum hemorrhage can occur after cesarean section or vaginal delivery. A uterine artery pseudoaneurysm can be fatal, so its detection and diagnosis are critical. Herein, we report a case of delayed postpartum hemoperitoneum due to uterine artery pseudoaneurysm rupture.
