Traumatic Pseudoaneurysm of the Occipital Artery Treated with Open Surgical Ligation: 2-Dimensional Operative Video.

Scalp pseudoaneurysms occur most commonly because of trauma and are often in the superficial temporal artery due to the lack of soft tissue coverage between skin and bone, making it more vulnerable anatomically.1,2 Pseudoaneurysms of the occipital artery (OA) also occur but are extremely rare.2-4 An 80-year-old man presented with scalp bleeding and a small left-sided posterior scalp laceration after a fall and head strike 10 days prior. He was admitted and during his 2-week hospital stay, the occipital laceration continued to rebleed (Video 1). He developed a 2-cm pulsatile ulcerative mass with central necrosis on the left nuchal ridge. Computed tomography angiography revealed an ovoid left occipital lesion measuring 1.3 × 2.5 × 2.3 cm with delayed contrast filling and partial thrombosis. The base of the lesion had dense contrast filling continuous with the OA, diagnostic of OA pseudoaneurysm. OA pseudoaneurysm may be treated endovascularly or surgically. While surgical resection is the most common treatment, minimally invasive techniques have been successfully done through direct injection of N-butyl cyanoacrylate or endovascular embolization. The clinical presentation of this case was unique because this patient had an ulcerated lesion with central necrosis overlying the pseudoaneurysm. Endovascular management alone would not address the open lesion, which is at high risk for infection. The risk of infection would increase after embolization of the occipital artery, causing further necrosis of the tissue.

Pseudaneurysm of the superolateral genicular artery following an anterior cruciate ligament reconstruction.

INTRODUCTION: Arthroscopic procedures are a safe way nowadays to do anterior cruciate ligament reconstruction. Rare complications involve injuries to popliteal vessels or one of its branches. PRESENTATION OF CASE: We present a case of a young patient who undergone an anterior cruciate ligament reconstruction. This procedure was associated with a meniscal suture. The follow-up was marked by pseudoaneurysm of the supero-lateral genicular artery. DISCUSSION: This is the first time a pseudoaneurysm of this branch is described in the literature as we discovered it. The treatment by an ultrasonography-guided embolization with thrombin was proceeded and suceeded. CONCLUSION: We stress the fact with new arthroscopic procedures and techniques, new complications can occur, and we should be attentive to them and new symptoms consequently, as a painless mass on the lateral side of the knee, to ensure a fast and optimal treatment.

Pulsatile Mass: Ruptured Common Femoral Artery Pseudoaneurysm with Active Extravasation.

Delayed rupture of a pseudoaneurysm represents an extremely rare and life-threatening complication of endovascular, radiographic, and cardiac procedures. We discuss a case of a 69-year-old man with delayed rupture of a known left common femoral artery pseudoaneurysm, highlighting the importance of rapid recognition, to include the use of point of care ultrasound, if available. Computed tomographic angiography allows for better anatomic characterization and aids in operative planning, which is the mainstay of treatment. However, surgical repair in ruptured pseudoaneurysms remains a high-risk procedure.

Pulsatile sterile abscess in the left breast following transapical transcatheter aortic valve implantation: a case report.

BACKGROUND: Over the last decade, transcatheter treatment of degenerative aortic valve stenosis has been established as an alternative to surgical aortic valve replacement. Late complications of transcatheter treatment of aortic stenosis (AS) are infrequent. CASE SUMMARY: We report an 87-year-old woman treated successfully with 23 mm Sapien 3 transapical transcatheter aortic valve implantation for severe AS. She presented 4 months later with a pulsatile mass in the left breast. After exclusion of other diagnoses, the mass was attributed to a sterile abscess communicating with the pericardial cavity due to post-operative chest infection and pleural effusion. Multimodality imaging helped to define the anatomy of the abscess and the mechanism of the pulsation. DISCUSSION: This is the first report of a pulsatile sterile abscess occurring as a complication of transapical aortic valve implantation. Multimodality imaging confirmed that the pulsation was due to extension of the abscess into the pericardial cavity, excluded direct communication with the left ventricle, and facilitated successful non-surgical management.

Pentalogy of Cantrell in Full Term Neonate.

Pentalogy of Cantrell (PC) is an uncommon congenital disorder characterized by severe defects in the chest and abdomen, including abdominal visceral prolapsed via umbilical cord (omphalocele), defect in the lower part of the sternum, defect in the front of the diaphragm, defects in the anterior part of the pericardium, and the ectopiacordis. Here, we report a 2-hour-old girl, weighing 3,500 g, who was referred to Shahid Madani Hospital in Khorramabad due to the large omphalocele on her chest with pulsating mass above it. The baby was the first child of a 24-year-old mother who was born with an uncomplicated vaginal delivery. Very rare cases of PC are born as a term new-born.

Successful treatment of a venous pseudoaneurysm in a brachiobasilic fistula using ultrasound-guided manual compression: two case reports.

A pseudoaneurysm or a false aneurysm is the consequence of a persistent blood leak caused generally by iatrogenic rupture of a vessel wall. In hemodialysis fistula, pseudoaneurysm results from repeated puncturing of the vein at the same site. Surgery and endovascular treatment stay widely used as the treatment of pseudoaneurysm compared to the ultrasound-guided manual compression (UGMC). UGMC is a non-invasive and effective procedure which could be attempted before invasive procedures. We reported two cases of successful treatment of pseudoaneurysm by ultrasound-guided compression. A total thrombosed cavity has been obtained and fistulas could be cannulated in the next session.

Pseudoaneurisma traumático de la arteria temporal superficial, reporte de un caso / Traumatic pseudoaneurysm of the superficial temporal artery, report of a case

Los pseudoaneurismas son una causa infrecuente de masa palpable en cabeza y cuello, habitualmente secundarios a procedimientos intervencionales; trauma e infeccioso son casos aislados. Caso Clínico. Se presenta el caso de un niño de 14 años que luego de haber sufrido un trauma contuso cortante en la región preauricular izquierda intervenido quirúrgicamente, desarrolla al mes un aumento de volumen pulsátil tras un trauma menor en la zona. En la ecografía se aprecia el signo del yin yang, indicador de pseudoaneurisma. Se realiza en pabellón el vaciamiento del pseudoaneurisma y posterior sutura vascular sin incidentes. Discusión. Pese a la baja frecuencia de pseudoaneurisma como causa de masa en cabeza y cuello, se debe considerar como diagnóstico diferencial en el contexto de masas pulsátiles post traumáticas, de horas a días de evolución. El estudio de elección es la ecografía doppler y el Gold Standard del manejo es quirúrgico con sutura vascular.

Pseudoaneurysms are an infrequent cause of palpable mass in the head and neck; usually secondary to invasive procedures; trauma and infectious causes are rare. Clinical Case. We present the case of a 14-year-old boy who, after suffering a blunt contusive trauma in the left preauricular region surgically treated, develops a month later a pulsatile volume increase after a minor trauma in the area. Ultrasound shows the yin yang sign, indicator of pseudoaneurysm. The emptying of the pseudoaneurysm and subsequent vascular suture was performed without incident. Discussion. Despite the low frequency of pseudoaneurysm as a cause of mass in the head and neck, it should be considered as a differential diagnosis in the context of post-traumatic pulsatile masses, from hours to days of evolution. The study of choice is Doppler ultrasound and the Gold Standard treatment is surgery with vascular suture.

Unusual clinical presentation of primary aortoduodenal fistula.

Primary aorto-enteric fistula (PAEF) develops between the native aorta and the gastro-intestinal tract, in the presence of an abdominal aortic aneurysm. It is a rare, life-threatening condition and appears to be less frequent than secondary aorto-enteric fistula, which is associated with previous aortic prosthetic reconstruction. When untreated, the overall mortality rate is almost 100%. Diagnosis may be challenging until the occurrence of a massive haemorrhage. In the presence of gross contamination, patients tend to a worse prognosis. Extra-anatomical bypass and repair of the enteric tract is the treatment of choice in case of gross contamination. In situ reconstruction is often reported in cases of mild bacterial contamination. Endovascular treatment has recently become a valid option in haemodynamically unstable patients, but a staged approach, with delayed surgical treatment, seems advisable.

Pseudoaneurisma post traumático de la arteria pedia: caso clínico / Post traumatic pseudoaneurysm of the pedal artery: case report

Pseudoaneurysm of the pedal artery is an uncommon condition that is usually caused by a traumatic injury or an iatrogenic intervention. The patient usually complains of an enlarging painless, pulsatile mass. We report a previously healthy 49 years old male presenting with a pulsatile mass of his left foot and a history of a traumatic lesion in the zone three months ago. A Doppler ultrasound examination confirmed the presence of a pseudoaneurysm of the pedal artery of 2.6 x 1.5 cm diameter. The patient underwent surgical resection of the mass and suture ligation of the artery. The postoperative period was uneventful.

Los pseudoaneurismas de la arteria pedia son infrecuentes y habitualmente se generan secundariamente a un traumatismo o a una intervención iatrogénica. Presentamos el caso de un paciente sano de 49 años que presenta un aumento de volumen pulsátil 3 meses posterior al traumatismo contuso de su pie izquierdo. En el doppler color se evidencia la presencia de un pseudoaneurisma de la arteria pedia de 2,64 x 1,53 cm. El paciente fue intervenido con resección y ligadura de la arteria con buena evolución postoperatoria.

Aneurisma único de arteria femoral común: caso clínico / Isolated common femoral artery aneurysm: case report

We report a 71 years old male with high blood pressure. During the postoperative follow up after a prostatectomy for a benign prostate hyperplasia, a pulsatile mass was palpated in the left inguinal region. A chest, abdomen and lower limb AngioTC, disclosed a unique sacular aneurysm in the left common femoral artery. The patient was subjected to a surgical excision of the aneurysm, with a favorable postoperative evolution.
