Pancreatic arteriovenous malformation (pAVM) is a very rare entity, as less than 100 cases are reported in the international literature. Patients with pAVM may be asymptomatic or may present a wide range of symptoms, such as vague pain, feeling of fullness, gastrointestinal bleeding, or even portal hypertension. We present the multimodality approach in the diagnosis of a patient with pAVM and treatment via transcatheter arterial embolization of the lesion using steel coils. The patient was free of symptoms 12 months later...

Though hemorrhaging pelvic arteries can be treated with transcatheter arterial embolization, difficulty in selection of injured arteries can lead to increased morbidity and mortality due to embolization of untargeted vasculature and prolonged time to hemostasis, resulting in unnecessary ischemic injury and prolonged hemorrhage. This report describes a balloon occlusion technique utilized in the setting of an unselectable hemorrhaging obturator artery.

INTRODUCTION AND AIM: To investigate the effect of mTOR inhibitor Rapamycin combined with transcatheter arterial embolization (TAE) on the growth, metastasis, and prognosis of hepatocellular carcinoma (HCC) in rat model. MATERIAL AND METHOD: McARH7777 cells were used to construct rat models of HCC, which were randomly divided into Model, Rapamycin, TAE, and Rapamycin + TAE groups. Quantitative reverse transcription-PCR (qRT-PCR) and Western Blot were used to detect the expression of Epithelial-Mesenchymal Transition (EMT)-related molecules, and immunohistochemical staining to determine the expression of EMTrelated proteins, angiogenic factors as well as microvessel density (MVD)-CD34...

Hemothorax is a common occurrence after blunt or penetrating injury to the chest. Posterior intercostal vessel hemorrhage as a cause of major intrathoracic bleeding is an infrequent source of massive bleeding. Selective angiography with trans-catheter embolization may provide a minimally invasive and efficient method of controlling bleeding refractory to surgical treatment. PRESENTATION OF CASE: A 19 year-old male sustained a gunshot wound to his left chest with massive hemothorax and refractory hemorrhage...

PURPOSE: Embolotherapies are commonly used for management of primary liver cancer. Explant studies of treated livers, however, reveal an untreated tumor in a high fraction of cases. To improve on this, we propose a new concept referred to as thermoembolization. In this technique, the embolic material reacts in local tissues. Highly localized heat energy is released simultaneously with the generation of acid in the target vascular bed. Combined with ischemia, this should provide a multiplexed attack...

BACKGROUND: Addition of nitroglycerine (NTG) to transcatheter arterial embolization/transarterial chemoembolization (TAE/TACE) has been shown to increase deposition of Lipiodol emulsion in hepatocellular carcinoma (HCC) tumors. The aim of this retrospective study was to evaluate if the addition of nitroglycerin (NTG) to TAE/TACE improved treatment response in HCC. METHODS: Patients with HCC either received (n=42) or did not receive (non-NTG) (n=111) NTG and an emulsion of Lipiodol with or without doxorubicin, followed by embolization with Gelfoam pledgets...

We encountered 2 patients with symptomatic huge simple renal cysts. In case 1, 4,000 mL of cyst fluid was drained via a catheter, but intracystic bleeding occurred immediately afterwards. Transcatheter arterial embolization (TAE) was performed, after which the bleeding stopped, and cyst drainage was repeated successfully. After 2 years, the total cyst volume was reduced from 11,775 mL to 75.4 mL. In case 2, TAE was performed prophylactically before drainage. Subsequently, 9,400 mL of fluid was removed from multiple cysts...

BACKGROUND: Spontaneous rupture of omental vessels is an infrequent medical condition possibly causing severe intra-abdominal hemorrhage. Omental bleeding results from trauma associated injury and irritation, neoplasia, arterial aneurysm rupture, and anticoagulant treatment. Idiopathic omental bleeding rarely causes acute abdominal bleeding which has been reported to occur in previous studies. Here we reported a case with idiopathic omental hemorrhage due to vascular malformation. A systematic review of literature is provided...

Late epistaxis after rhinoplasty is a rare but potentially life-threatening occurrence. This case report concerns a 20-year-old woman who had severe epistaxis 5 and 10 days after a closed rhinoplasty with internal osteotomies and who ultimately required transcatheter arterial embolization for definitive control of the hemorrhagic source. Arterial hypervascularity, with signs of arteriovenous malformation, of the midface at the level of the piriform aperture and maxilla was seen on angiography.

An 85-year-old female suffered pelvic fracture, multiple rib fractures, right hemopneumothorax, and blunt abdominal aortic injury in a traffic accident. After transfer to our hospital, transcatheter arterial embolization (TAE) was performed immediately for hemorrhage from the bilateral internal iliac arteries. Enhanced computed tomography (CT) after TAE showed an increase of hematoma and extravasation at the bifurcation of the abdominal aorta. Therefore, emergency abdominal endovascular aortic repair was performed on the same day...

Simultaneous anterior and posterior traumatic dislocations of both hips are very rare. Only 33 cases have been previously reported in the English language literature. Although they were all due to high-energy injuries, they were hemodynamically stable and had a stable pelvic ring. We report a unique case of asymmetrical hip dislocations with an unstable pelvic ring and hemodynamic instability. A 40-year-old man was injured in a high-energy motor vehicle accident. He was hemodynamically unstable when he presented in the emergency department...

Numerous studies concerning hepatic arterial infusion chemotherapy (HAIC) have been conducted by adopting regimens containing 5-fluorouracil (FU), with a favourable efficacy compared with conventional transcatheter arterial chemoembolisation (TACE) treatment; however, the detailed mechanism of HAIC remains unclear. The present study aimed to evaluate peripheral concentration time curves of 5-FU administered through the hepatic artery, which may additionally explain the mechanism of action of HAIC. A total of 10 eligible patients underwent transcatheter arterial embolization and a 2-day HAIC treatment regimen using a folinic acid, fluorouracil and oxaliplatin regimen...
