Inferior phrenic artery to pulmonary artery fistulae are a rare anomaly seen on CT thorax angiogram when evaluating for certain pulmonary pathological conditions. A 79-year-old man with hemothorax on chest X-ray was evaluated by interventional radiology for embolization of a bleeding vessel. During the procedure, a fistulous connection between the right inferior phrenic artery and right pulmonary artery with signs of extravasation was found and embolized, significantly reducing the size of the hemothorax. This case demonstrates that inferior phrenic artery to pulmonary artery fistulae, a rarely seen vascular anomaly, can result in life-threatening hemothorax.

We demonstrate an aberrant ramification pattern of the renal and testicular vessels. On both sides, the anterior and posterior renal veins emerged from the renal. On the right side, the anterior renal vein collected the right testicular vein and drained into the inferior vena cava, while the posterior one directly drained into the inferior vena cava.

Median arcuate ligament syndrome (MALS) is a rare condition characterized by nonspecific symptoms, such as abdominal pain, nausea, and vomiting. Furthermore, the development and rupture of pancreaticoduodenal artery aneurysms pose a potentially fatal risk. Median arcuate ligament release (MALR) is useful in the treatment of MALS, with most procedures performed laparoscopically.

Background/aim: Although transarterial chemo-embolization (TACE) is a key treatment for hepatocellular carcinoma (HCC), its effectiveness depends on the cannulation of the microcatheter tip into the feeding artery. Steerable microcatheters allow remote operation of the tip, enabling its insertion into feeding arteries otherwise difficult to reach. This study investigated the indications and effectiveness of steerable microcatheters in TACE for HCC.

Article Synopsis
- Pulmonary arteriovenous malformation (PAVM) involves abnormal connections between pulmonary arteries and veins, sometimes linked to systemic arteries, which can cause health issues like hemoptysis (coughing up blood).
- A 33-year-old male with intermittent bloody sputum was diagnosed with a rare congenital PAVM connected to the inferior phrenic artery, treated successfully with endovascular embolization, which blocks the abnormal blood flow.
- The procedure proved to be effective and safe, as the patient did not experience further bleeding after one year, highlighting the importance of recognizing and treating such rare conditions.

Article Synopsis
- Gastric submucosal arterial dilation from splenic artery occlusion can lead to rare but severe acute upper gastrointestinal bleeding (UGIB), with limitations in detection by endoscopy.
- A case involving a 57-year-old male revealed massive UGIB linked to a tortuous left inferior phrenic artery, previously noted "gastric varices," and subsequent endoscopic failure that required transcatheter arterial embolization (TAE) for treatment.
- This case is the first to identify UGIB from a tortuous left inferior phrenic artery and underscores the need for alternative methods like TAE to manage arterial bleeding when endoscopy is inadequate.
