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.

PURPOSE:
To explore the diagnosis and treatment of traumatic external carotid branch pseudoaneurysms.
METHODS:
Eleven cases of traumatic external carotid artery branch pseudoaneurysms were admitted in our hospital. Digital subtraction angiography was performed in all patients. It revealed that the pseudoaneurysms originated from the internal maxillary artery in 5 cases, superficial temporal artery in 5 cases and occipital artery in 1 case. Five cases of internal maxillary artery pseudoaneurysms and 2 cases of superficial temporal artery pseudoaneurysms were treated by embolization; the other 3 cases were surgically resected.
RESULTS:
Complete cessation of nasal bleeding was achieved in all the 5 pseudoaneurysms of internal maxillary artery after the endovascular therapies. Scalp bleeding stopped and scalp defect healed up in 2 patients with superficial temporal artery pseudoaneurysms treated by interventional therapy. All patients were followed up for 0.5-2.0 years without recurrence of nosebleed and scalp lump.
CONCLUSION
For patients with repeated severe epistaxis after craniocerebral injury, digital subtraction angiography should be performed as soon as possible to confirm traumatic pseudoaneurysm. Endovascular therapy is an effective method for traumatic internal maxillary artery pseudoaneurysms. For patients with scalp injuries and pulsatile lumps, further examinations including digital subtraction angiography should be performed to confirm the diagnosis. Surgical treatment or endovascular therapy for scalp traumatic pseudoaneurysm is effective.

OBJECTIVE:
This report aims to raise physician clinical awareness of radial artery pseudoaneurysm (RAP) and promote early recognition of this potentially serious complication. The article highlights various proposed treatment strategies in the management of this condition.
BACKGROUND:
Radial artery pseudoaneurysm is a rare potentially serious complication following transradial artery coronary angiography for left heart catheterization and percutaneous coronary intervention. Risk factors associated with the development of RAP include multiple arterial puncture attempts, use of systemic anticoagulation, inadequate hemostasis following post-procedural compression, vascular site infection, use of larger sheaths, female gender, age of 70 years and older, diabetes mellitus, obesity and/or patients with high body mass index.1-3 Conservative medical treatment and/or surgical repair are the primary therapeutic approaches in the management of RAP.
CONCLUSION
Transradial artery access is associated with a significantly lower risk of major bleeding and vascular access site complications, reduces morbidity and mortality compared with the transfemoral approach. It is important to recognize though that complications do still occur with the transradial approach. RAP is one such entity wherein prevention is key - with adequate post-procedural compression, frequent observation, and careful assessment of the radial access site.
