Spontaneous rupture of an intercostal artery (ICA) is a rare but could be a life-threatening emergency requiring prompt diagnosis and intervention for optimal outcome. We report a patient presented with swelling in his right-side back which started immediately after scheduled hemodialysis and continued to increase in size. Contrast computed tomography scan revealed soft tissue attenuated lesion with internal enhancing dots which suggested expanding hematoma with active bleeding. Arteriography detected focal contrast extravasation from seventh ICA, and transcatheter arterial embolization was successfully done...

Major aortopulmonary collateral arteries branching from coronary arteries may cause coronary steal. The careful follow-up is needed irrespective of symptoms because increasing physical activities and oxygen demand along with the age may induce myocardial ischemia. Transcatheter intervention by well-trained physician would be a treatment option in patients with myocardial ischemia.

Transcatheter arterial embolization (TAE) is the best non-laparotomy choice for solid visceral organs rupture and bleeding nowadays. In our previous study, a new biodegradable macromolecule material thrombin-loaded alginate-calcium microsphere (TACM) was prepared and its characteristics were investigated preliminarily. In this study, we further investigated the biocompatibility of TACMs, as well as physical characteristic, application method and effect of TACMs with thrombus (embolic agent). The in vivo results attested that TACMs were non-irritating and non-genotoxic with desired biocompatibility, although brought about a slight and temporary inflammation...

Transcatheter arterial embolization has become a common management option for intractable postpartum uterine hemorrhage. Iodinated contrast agents are commonly used for embolotherapy but cannot be used in patients with renal dysfunction or iodine allergy. A 37-year-old woman spontaneously delivered a healthy girl but developed severe postpartum uterine hemorrhage, probably due to placenta accrete. Contrast-enhanced computed tomography revealed extravasation of the iodinated contrast agent into the uterine cavity...

A 65-year-old woman with no significant medical history visited the emergency department complaining of epigastric discomfort. A computed tomography of the thorax and abdomen showed the attenuation of the pulmonary artery and a posterior mediastinal hematoma. Angiography showed a tortuous esophageal branch of the left gastric artery and a pseudoaneurysm, and during the later phase, the left lower lobe of the lung was enhanced, and finally, the left pulmonary vein was enhanced. We considered that the patient was exhibiting hypoperfusion of the left pulmonary artery arising from left pulmonary artery hypoplasia, since the left lung was supplying the systemic circulation...

Splenic rupture is a rare but serious complication from cocaine abuse. Given the ubiquitous prevalence of abuse and the potential for death from intraperitoneal bleeding, the prompt diagnosis and treatment of cocaine-induced disease including splenic rupture is essential. The management for splenic rupture from traumatic and atraumatic etiology has shifted from emergent laparotomy and splenectomy to non-operative approach with transcatheter splenic artery embolization. We report a 39-year-old male with a significant substance abuse history who presented with atraumatic splenic rupture...

Traditional percutaneous balloon angioplasty and stent placement is based on mechanical plaque disruption and displacement within the arterial wall. On the contrary, transcatheter atherectomy achieves atherosclerotic plaque clearance by means of directional plaque excision or rotational plaque removal or laser plaque ablation. Debulking atherectomy may allow for a more uniform angioplasty result at lower pressures with consequently less vessel barotrauma and improved luminal gain, thereby decreasing the risk of plaque recoil and dissection that may require permanent metal stenting...

The incidence of hepatocellular carcinoma (HCC) spontaneous tumor rupture varies between 3% and 26%. For resectable HCC ruptures, emergency hepatectomy or staged hepatectomy after transcatheter arterial embolization (TAE) are life-saving procedures, and efficient therapeutic methods. We report a multimodal therapy including TAE, associating liver partition and portal vein ligation (ALPPS) and immunoglobuline infusion for a huge bleeding HCC with portal vein tumor thrombosis (PVTT) in hepatitis B virus (HBV) cirrhosis...
