Pseudoaneurysm

BACKGROUND: Whether patients with incomplete myocardial rupture (IMR) present distinctive clinical and cardiac magnetic resonance features from those with moderate-severe pericardial effusion (⩾10 mm (PE)) remains unknown Methods: We compared the clinical, angiographic and cardiac magnetic resonance characteristics of nine patients with IMR (diagnosed angiographically and/or by cardiac magnetic resonance) with 29 with PE, and also with 38 without IMR or PE with evidence of transmural necrosis (reference group) matched for age, gender and year of admission...

Coronary artery fistulas are rare anomalous vascular connections between coronary arteries and a cardiac chamber or a central vessel, without an intervening capillary bed. Coronary-pulmonary fistulas are a distinct subset of coronary artery fistulas. We present the case of a previously healthy 63-year-old-man who presented with chest pain and was found to have mediastinal haemorrhage. Upon further investigations, he was found to have multiple coronary-pulmonary fistulas with pseudoaneurysm formation in three of the fistulas...

BACKGROUND: Pulmonary artery aneurysms constitute <1% of aneurysms occurring in the thoracic cavity. Congenital cardiac defects are responsible for the majority (>50%) of cases, however, pulmonary artery aneurysm is a rare sequelae of pulmonary tuberculosis reported in about 5% of patients with chronic cavitary tuberculosis on autopsy. The natural history of this potentially fatal condition remains poorly understood and guidelines for optimal management are controversial. CASE PRESENTATION: A 24-year-old man, a nursing student of African descent, was referred to us from an up-country regional hospital with a 4-week history of recurrent episodes of breathlessness, awareness of heartbeats and coughing blood 3 weeks after completing a 6-month course of anti-tuberculosis drugs...

Posttraumatic pseudoaneurysms are extremely rare in pediatric populations. In many cases, pseudoaneurysms may be confused with abscesses, epidermoid cysts, arteriovenous fistula, foreign objects, and ganglion cysts, as well as tumors. They are associated with distinguishing findings of "pulsatile mass, a palpable thrill, and an audible to-and-fro murmur" (1), which can be confirmed by various imaging techniques. In this report, we describe the case of a 4-year-old boy who presented to the pediatric emergency department 3 weeks after falling and subsequently getting cut by glass...

BACKGROUND: Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability. METHODS: A multicenter, retrospective review of patients with subclavian or axillary artery injuries from 1/1/2004-12/31/2014 was completed at 11 participating Western Trauma Association institutions...

BACKGROUND AND AIMS: Transmural drainage with double-pigtail plastic stents (DPPSs) was the mainstay of endoscopic therapy for symptomatic peri-pancreatic fluid collections (PPFCs) until the introduction of lumen-apposing covered self-expanding metal stents (LAMSs). Currently, there is limited data regarding the efficacy and adverse event rate of LAMS compared with DPPS. METHODS: A retrospective analysis of EUS-guided PPFC drainages at a single tertiary care center between 2008 and 2015 was performed...

BACKGROUND: Iatrogenic vertebral artery injury (VAI) during anterior cervical surgery is rare but potentially catastrophic. METHOD: The causes, presentation, diagnosis, management, prognosis, and prevention of VAI were reviewed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. English-language studies and case reports published from 1980 to 2017 were retrieved. Data on diagnosis, surgical procedures and approach, site and cause of VAI, management, outcomes, and VA status were extracted...

Uterine artery pseudoaneurysm is a rare but potentially life-threatening complication that can occur after various uterine manipulations. A 34-year-old nulliparous patient with a previous history of four consecutive miscarriages with unknown etiologies underwent transmyometrial oocyte retrieval as a result of malpositioning of the right ovary. Six days later, she experienced massive vaginal bleeding after a day of intermittent bleeding and was transferred to our hospital. At triage, continuous bleeding from the cervical canal was observed...

We present a case of supraclinoid internal carotid artery dissection. Eleven months prior, the patient developed isolated periorbital pain and was diagnosed with giant-cell arteritis with iritis. The patient experienced recurrent spells concerning for transient ischaemic attacks and was transferred to our institution for endovascular intervention after head CT revealed an embolic infarct with a 'dense middle cerebral artery sign.' Digital subtraction angiography was negative for occlusion, instead demonstrating luminal stenosis and poststenotic dilatation...

BACKGROUND: Pituicytoma is a rare tumor originating from glial cells of the adult neurohypophysis and infundibulum. Surgical removal is the treatment of choice for this neoplasm. In recent years the endoscopic endonasal approach has proven to be a viable and effective alternative to standard craniotomy. CASE DESCRIPTION: We report a case of a patient submitted to surgical treatment for a recurrence of pituicytoma, which was operated on transcranially at another hospital approximately five years previously...

Popliteal injuries are well known to be serious with a high rate of mortality due to damage caused to popliteal vessels. Pseudoaneurysm formation and arteriovenous fistulas are well-known complications of arterial injury, but are rarely concomitant. Diagnosis is usually done by computed tomography (CT) angiography. Treatment strategies consist of surgery or endovascular management. We report the surgical treatment of two cases of popliteal arteriovenous fistula associated with pseudoaneurysm complicating stab wounds...

Ultrasound-guided thrombin injection has been shown to be a safe and effective treatment for iatrogenic post-catheterization pseudoaneurysms, but still is underused in France. We report our single-center experience and propose a technical guideline for ultrasound-guided thrombin injection. Ultrasound-guided thrombin injection should be considered to be the first-line treatment of iatrogenic pseudoaneurysms.

INTRODUCTION: Pseudoaneurysms are a pulsatile hematoma caused by hemorrhage on soft tissues. It is an uncommon condition with many different etiologies. We report a case of a giant pseudoaneurysm caused by iatrogenic injury on the brachial artery. PRESENTATION OF CASE: A 42 year-old male was submitted to our Vascular Surgery service with an enlargement of the right upper limb and a history of myocardial infarction. 60days before the patient reached our service, he was submitted to a cardiac catheterization performed by another medical team, since the catheter was placed on the right brachial artery near the cubital fossa, we suspected an iatrogenic pseudoaneurysm, which was confirmed by his clinical history and physical exam...

BACKGROUND Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. MATERIAL AND METHODS A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. RESULTS A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13...

A pseudoaneurysm or false aneurysm of the brachial artery is an uncommon occurrence in patients receiving hemodialysis with arteriovenous fistula (AVF). We describe the case of a 76-year-old woman presenting with a large, tender, pulsatile mass in the right antecubital region 10 cm from the AVF. B-mode ultrasound examination revealed a saccular hematoma. Color doppler showed a recirculation movement of blood, creating a two colors image called "Korean flag". The patient was transferred to the surgical unit where she first underwent ultrasound-guided compression and then surgical repair of the pseudoaneurysm...

Reported here is a case of 1-year-old male child who presented with huge abdominal mass, which on radiological investigation was diagnosed as retroperitoneal pseudoaneurysm of the aorta. On exploration, it was found to be a true aneurysm of infrarenal abdominal aorta with inflow agenesis. Aneurysm was excised, and aorta was reconstructed with 10 mm Dacron graft. Postoperative computed tomography angiography showed patent graft with good distal runoff. Literature review revealed that only 26 cases of congenital abdominal aortic aneurysm had been reported so far...

Pseudoaneurysms (PSAs) of the hepatic and/or cystic artery are a rare complication following a laparoscopic cholecystectomy (LC). Generally, PSA cases present with haemobilia several weeks following the procedure. Transarterial embolisation (TAE) is considered the optimal management approach. We report a 70-year-old woman who presented to the Sultan Qaboos University Hospital, Muscat, Oman, in 2016 with massive hemoperitoneum two weeks after undergoing a LC procedure in another hospital. She was successfully managed using coil TAE...
