[A pulsatile mass on the forehead after a fall]. / Een bult op de slaap na een val.

A 84-year-old man presented with a pulsatile mass on the forehead 2 weeks after blunt head injury. Doppler ultrasonography showed a yin-yang sign. The man was diagnosed with a pseudoaneurysm of the left superficial temporal artery.

Popliteal pseudoaneurysm and arteriovenous fistula after acupuncture.

Most popliteal arteriovenous fistula and pseudoaneurysm formation are related to trauma. Few cases have previously been reported after acupuncture therapy. Such events are typically observed when the procedure is performed by non-medical acupuncturist. They may present with acute ischemia, recent claudication, distal emboli, or less commonly rupture. Duplex ultrasound should be considered as the 1st method of investigation. Computed tomography scanning is particularly accurate in making the diagnosis. Treatment strategies consist of surgery or endovascular management. The most commonly performed surgical technique for popliteal pseudoaneurysm repair is resection with bypass grafting, whereas popliteal arteriovenous fistula are usually treated surgically with ligation and primary repair. Endovascular procedure using a stent-graft is thought to be a reasonable option for treating popliteal false aneurysm or even arteriovenous fistula. We will describe two cases of an arteriovenous fistula and pseudoaneurysm of the popliteal artery that developed after acupuncture needling in the region of the popliteal artery.

[A man with a bump on his forehead after a fall]. / Een man met een bult op zijn voorhoofd na een val.

UNLABELLED: An 84-year-old male patient presented with a swelling on his forehead which had developed gradually over a period of three weeks after a fall. Ultrasound examination revealed a complex fluid collection with a yin-yang flow pattern (revealed by colour Doppler imaging), which was suggestive of a pseudoaneurysm of the frontal branch of the superficial temporal artery. This was successfully treated with an injection of thrombin. DIAGNOSIS: traumatic pseudoaneurysm of the superficial temporal artery.

Pseudoaneurisma de carótida comum secundário a trauma contuso: opção de tratamento por cirurgia a céu aberto / Pseudoaneurysm of common carotid due to trauma: treatment option for open sky surgery

Relato de caso de paciente feminina, com 44 anos de idade, vítima de trauma cervical em acidente de trânsito, que apresentou massa cervical dolorosa, rouquidão e disfagia associados, três semanas após o trauma. Exames complementares identificaram pseudoaneurisma de carótida comum em zona II. Optou-se pelo tratamento por meio de cirurgia convencional a céu aberto com excelente resultado imediato. Foi realizado um exame de controle após sete meses do procedimento cirúrgico, e os resultados confirmaram o sucesso terapêutico.

Case report of a female patient, 44 years-old, victim of cervical trauma in a traffic accident, who had painful cervical mass, associated with hoarseness and dysphagia three weeks after trauma. Additional tests identified the pseudoaneurysm of common carotid artery in zone II. We opted for treatment through the open conventional surgery with excellent immediate result. Control examination was performed seven months after surgery, and the results confirmed the therapeutic success.

Hemobilia as a late complication after blunt abdominal trauma: a case report and review of the literature.

BACKGROUND: Bleeding within the biliary tree, called hemobilia, is a rare complication after blunt hepatic trauma. OBJECTIVES: To report on a patient who developed hemobilia 1 month after a blunt abdominal injury and to discuss the diagnosis and treatment of hemobilia. CASE REPORT: A 17-year-old boy presented with upper gastrointestinal bleeding caused by hemobilia 1 month after a blunt liver injury. Angiography revealed a pseudoaneurysm of the right hepatic artery, which was successfully treated with embolization. CONCLUSIONS: The diagnosis of hemobilia first requires consideration of the diagnosis, particularly in patients with previous abdominal trauma. Hemobilia should be included in the differential diagnosis of upper gastrointestinal bleeding. Investigations of choice include computed tomography scan followed by angiography. During angiography, treatment can be done by endovascular embolization.

Ultrasound and magnetic resonance angiography features of post-traumatic ulnar artery pseudoaneurysm: a case report and review of the literature.

Ulnar artery pseudoaneurysms are very uncommon. The least common etiological mechanism is a single direct trauma. It is important to identify these lesions, which may have important clinical complications such as distal thrombosis with digital ischemia or gangrene. This report describes the features of sonography and magnetic resonance angiography of a histologically confirmed ulnar artery pseudoaneurysm.
