Portal vein thrombosis (PVT) is a disease in which thrombosis occurs from the intrahepatic branches of the portal vein, and may extend to the splenic vein and/or superior mesenteric vein. It is most often associated with liver cirrhosis. PVT not associated with cirrhosis is rare.

Among these, thoracic aorta injury caused by penetrating trauma is a cause of elevated morbidity and mortality, demanding adequate diagnosis, and can now often be repaired using endovascular procedures. This treatment method has proven to be safer, with a lower rate of complications than open surgical procedures.

- Aortic injuries from blunt chest trauma have high mortality rates, and while the endovascular approach is a treatment option, its outcomes are still not fully understood.
- The study reviews the experiences of a trauma center in Curitiba, Brazil, focusing on patients who sustained blunt trauma to the thoracic aorta, primarily from vehicle accidents.
- Sixteen patients were treated using endografts, with low complications observed, highlighting the endovascular method's viability, though further research is needed for more definitive conclusions.
Article Synopsis
- Abdominal aortic aneurysms (AAAs) are the most frequent type of aneurysm, particularly in patients with kidney transplants, highlighting a gap in understanding their prevalence in this group.
- A case study discusses a kidney transplant recipient who had an AAA and a contrast allergy, requiring a bi-iliac aortic bypass for repair.
- The patient successfully underwent surgery with a temporary bypass using the right axillary artery and was stable enough to be discharged just two days post-operation, suggesting that open surgery can be a viable option for AAA treatment in kidney transplant patients.
Article Synopsis
- Aortic dissection treatment is complex and controversial, requiring personalized approaches due to serious complications and challenging diagnosis.
- A case study describes a 61-year-old male smoker with poorly controlled hypertension who experienced a Stanford type B aortic dissection, initially treated with medication.
- After drug treatment failed, endovascular techniques were successfully used to place a stent, showing promising survival rates after one year.
