The spontaneous rupture of an ovarian artery aneurysm (OAA) is an extremely uncommon and life-threatening event. Here, we describe the case of a 34-year-old G6P5015 female who underwent spontaneous vaginal delivery. Following delivery, she experienced hypotension and reported right-sided abdominal pain. A contrast-enhanced computed tomography (CT) angiogram revealed an aneurysmal dilation, extravasation, pseudoaneurysms, and a large retroperitoneal hematoma attributable to a rupture of the right ovarian artery. Subsequently, an exploratory laparotomy was performed, and then a transcatheter arterial embolization (TAE) by interventional radiology (IR). At a proximal site, IR successfully embolized both the ovarian and uterine arteries. This case highlights the significance of rapid intervention in managing an OAA. Additionally, we discuss the risk factors and treatment alternatives for OAA, underscoring the importance of considering it in the differential diagnosis when encountering atypical hypotension in the postpartum period.

Endoscopic retrograde cholangiopancreatography (ERCP) remains the main therapeutic modality towards the management of common bile duct (CBD) stones and dilatation of strictures. It also has varied diagnostic roles including brush biopsy. The procedure still is associated with side effects and increased morbidity and mortality. One side effect is bleeding. This may be associated with procedural trauma or bleeding following post-traumatic pseudoaneurysm delayed-onset bleeding. Although it may be argued that inflammation surrounding the biliary duct area and in particular the pancreas could also contribute to the delayed bleeding along the ampullary region, we present a case of delayed pseudoaneurysm bleeding that was successfully managed post-ERCP via interventional radiology-guided embolization.

Colonic variceal bleeding is a rare cause of lower gastrointestinal (GI) bleeding, which carries a high mortality rate. Due to limited data, the optimal management of colonic variceal bleeding is not known. Coil-assisted retrograde transvenous obliteration (CARTO) has been shown to be very effective in managing non-esophageal variceal bleeding, but only a few cases demonstrate its effectiveness in treating colonic variceal bleeding. Here we present a case of colonic variceal bleeding treated with CARTO in order to expand on the limited body of evidence showing its efficacy in effectively treating this rare cause of life-threatening GI bleeding.

Pseudoaneurysms of the middle rectal artery are rare. When encountered, these have the potential for significant morbidity and mortality due to bleeding and potential rupture. Endovascular embolization is a feasible option in the management of these pseudoaneurysms. The present report describes a case of a 43-year-old male presenting with hemorrhagic shock secondary to lower gastrointestinal bleeding one day after undergoing excision of an external perineal condyloma, incision and drainage of a perirectal abscess, and biopsy of a perianal mass. Angiographic imaging revealed a right middle rectal artery pseudoaneurysm. Selective embolization of the right middle rectal artery and bilateral superior rectal arteries was successfully performed. At the two-week post-embolization follow-up, hemoglobin was stable, and the patient reported normal bowel movements with no episodes of bleeding per rectum.

Retroperitoneal hematomas are a rare and fatal complication of endovascular embolization. We report a case of an 89-year-old woman who was referred to interventional radiology for percutaneous embolization for intractable epistaxis as a result of a left nasal cavity mucosal melanoma. After successful embolization of the left sphenopalatine artery, the patient became hypotensive and was transferred to the intensive care unit. Post-operative CT abdomen and pelvis angiogram showed a large right perinephric hematoma, which is an extremely uncommon complication of endovascular embolization for epistaxis. Practitioners should be aware of this life-threatening complication in weighing the risks and benefits of embolization versus direct surgical ligation, and they should identify and intervene promptly if a retroperitoneal hematoma should occur.

Deep venous thrombosis (DVT) is the most common cause of unilateral lower limb swelling. Common differential diagnosis includes superficial thrombophlebitis and ruptured Baker\'s cyst. DVT is one of the most common complications diagnosed following lower extremity orthopedic surgery. However, many less frequent causes are often easily overlooked. Here we present a case of a 65-year-old man with a previous hip replacement who developed left-sided progressive leg swelling for years, which was managed initially with anticoagulation for provoked DVT and with compression stockings for post-thrombotic syndrome with no improvement. There was arterialization and spectral broadening of the venous waveform in the Doppler study. Computed tomography angiogram of the lower limbs showed evidence of arteriovenous fistula (AVF) with opacification of the deep left leg veins. Angioplasty and embolization of the fistula resulted in the resolution of leg swelling. We also discussed similar cases found in the literature. AVF needs to be considered in patients presenting with unilateral leg swelling following lower extremity orthopedic surgery.
