Article Synopsis
- The Indigo Aspiration System is a catheter-based device designed for removing clots in peripheral arteries and veins, recently launched in Japan for treating acute limb ischemia.
- The first use of this system involved a 96-year-old man suffering from acute lower limb ischemia due to an embolism related to a left common iliac artery aneurysm.
- The treatment resulted in a notable improvement in blood flow to the patient's left foot, highlighting the device's effectiveness and relevant use cases.
After previous earthquakes, high prevalence of cardiovascular diseases including venous thromboembolism (VTE) has been reported. We performed venous screening at the site of Hokkaido East Iburi Earthquake which happened at 6th September 2018. VTE screening using ultrasound sonography was performed for total 7 days at Atsuma town, Mukawa town and Abira town (total 9 shelters).

- * A case involved an 80-year-old man misdiagnosed with an infected internal iliac artery aneurysm; treatment was delayed, leading to complications before discovering the correct diagnosis of diffuse large B-cell lymphoma.
- * The case emphasizes that distinguishing between malignant lymphoma and infected aneurysms is difficult and suggests that histological exams should be conducted for atypical presentations to avoid misdiagnosis and unnecessary surgeries.
Secondary aortoenteric fistula or erosion (SAEFE), an abnormal connection between the aorta and gastrointestinal tract, is a rare but critical complication after abdominal aortic aneurysm repair. Most SAEFEs occur between the aorta or proximal graft anastomosis and the duodenum, and occurrence between the iliac graft and small intestine is rare. Standard SAEFE management involves graft removal and extra-anatomical bypass.

- An 82-year-old woman with chronic limb-threatening ischemia developed bilateral heel ulcers that were challenging to treat.
- After undergoing a bypass surgery on her right leg, she faced complications like osteomyelitis, which made healing difficult.
- The patient eventually required a partial calcanectomy for both heels, leading to successful healing after the procedures.
A coronary artery fistula (CAF) is an abnormal connection between a coronary artery and a cardiac chamber or a great vessel. CAF draining into the main pulmonary artery, called coronary-to-pulmonary artery fistula (CPAF), is one of the common variations of CAF. Although there is no definitive surgical indication of CPAF, it is treated concomitantly during other cardiac surgeries.

However, lung hernia has been reported as a rare complication of minimally invasive cardiac surgery (MICS), and normally requiring additional surgical procedures. We describe herein a case of manual repositioning of lung hernia after MICS.

In this case report, we describe a 23-year-old female with peripartum cardiomyopathy. She had a persistently low cardiac index despite intensive care with intravenous inotropes, intra-aortic balloon pumping and extracorporeal membrane oxygenation; thus, we implanted an extracorporeal left ventricular assist device.
