We report a neonate with transposition of great arteries and intact ventricular septum who had a massive pulmonary hemorrhage soon after an arterial switch operation. An emergency cardiac catheterization revealed a large bronchial collateral artery from the descending aorta feeding the right lung. The hemorrhage was controlled by coil embolization of the collateral, and the patient recovered after prolonged intensive care.

Major aortopulmonary collateral arteries can influence the postoperative course of arterial switch operation, with heart failure being the common clinical presentation. A relatively rare presentation of an aortopulmonary collateral artery in the form of persistent postoperative pulmonary hemorrhage was encountered after an uneventful arterial switch operation in a neonate with transposition of the great arteries, intact interventricular septum, and situs inversus totalis. The aortopulmonary collateral artery was coil embolized with a successful outcome...

We report a patient with life-threatening hematemesis caused by the rupture of a ductus aneurysm into the esophagus, which was successfully treated by coil embolism for the esophageal fistula through the aorta and subsequent thoracic endovascular aortic replacement. Second-stage therapy was performed surgically after proactive antibiotic treatment and in consideration of the patient's improved general condition. This included debridement with drainage, aortic encasement with remnant aneurysmal wall, omentopexy, and jejunostomy...

RATIONALE: Hepaticarterioportal fistula (APF) is a rare cause of portal hypertension and gastrointestinal hemorrhage, and presents as abnormal communication between the hepatic artery and portal vein. Percutaneous liver biopsy is a main iatrogenic cause of AFP. However, non-iatrogenic, abdominal, trauma-related APF is rarely reported. PATIENT CONCERNS: A 29-year-old man presenting with severe, watery diarrhea was transferred to our hospital, and his condition was suspected to be acute gastroenteritis because he ate expired food and suffered a penetrating abdominal stab wound 5 years ago...

Endovascular interventional procedures are widely used for the treatment of intracranial vascular lesions. However, they sometimes produce reversible alopecia, known as radiation-induced temporary alopecia, depending on the radiation dose. Radiation-induced temporary alopecia manifested as rectangular alopecic patches without signs of inflammation, reflects damage to the keratinocytes in the hair matrix of anagen hair follicles, due to the sensitivity of these cells to radiation. The characteristics of radiation-induced temporary alopecia are similar to those of alopecia areata as follows: (1) clinical findings of well-defined alopecic patches and (2) dermoscopic findings of yellow dots, black dots, and short vellus hairs...

BACKGROUND AND PURPOSE: Endovascular embolization of intracranial aneurysms with hydrogel-coated coils lowers the risk of major recurrence, but technical limitations (coil stiffness and time restriction for placement) have prevented their wider clinical use. We aimed to assess the efficacy of softer, second-generation hydrogel coils. METHODS: A randomized controlled trial was conducted at 22 centers in France and Germany. Patients aged 18 to 75 years with untreated ruptured or unruptured intracranial aneurysms measuring 4 to 12 mm in diameter were eligible and randomized (1:1 using a web-based system, stratified by rupture status) to coiling with either second-generation hydrogel coils or bare platinum coils...

OBJECTIVE Although endovascular therapy is favored for acutely ruptured intracranial aneurysms, hematological factors associated with acute subarachnoid hemorrhage (SAH) may predispose to procedure-related ischemic complications. The aim of this study was to evaluate whether an elevated level of plasma D-dimer, a parameter of hypercoagulation in patients with acute SAH, is correlated with increased incidence of thromboembolic events during endovascular coiling of ruptured aneurysms. METHODS The authors analyzed data from 103 cases of acutely ruptured aneurysms (in 103 patients) treated with endovascular coil embolization at a single institution...

Thoracoabdominal aortic aneurysms are among the most challenging pathologic conditions vascular surgeons have to face. Endovascular treatment brought the prospect of being able to treat these complex aneurysms with less invasiveness and recent outcomes already challenge those of open repair. Plus, this technique offers a therapeutic option for patients who had none, due to significant comorbidities limiting open repair. Spinal cord injury is a major complication after complex aneurysm repair that dramatically affects patient's quality of life, even if technical success - aneurysm exclusion from circulation - has been achieved...

Introduction: Cryptogenic stroke is present in about 40% of ischemic stroke patients. Extracardiac shunt related to pulmonary arteriovenous fistula (PAVF) could be a rare potential risk factor for embolic stroke. Most PAVFs are multiple, congenital, and associated with hereditary conditions. On the other hand, isolated PAVFs are rare conditions and an uncommon cause of cryptogenic stoke. Case Report: We describe a case of a young woman without history of respiratory diseases or vascular risk factors, who presented with acute onset of transitory aphasia and right hemiplegia...
