Acute portal vein and mesenteric vein thrombosis (PVMVT) can cause acute mesenteric ischemia and be fatal with mortality rate of 37%-76%. Therefore, early diagnosis and prompt venous revascularization are warranted in patients with acute symptomatic PVMVT. Due to advances in catheter-directed treatment, endovascular treatment has been used for revascularization of affected vessels in PVMVT. We report two cases of symptomatic PVMVT treated successfully by transhepatic percutaneous mechanical thrombectomy-assisted thrombolysis.
Cardiovascular diseases (CVDs) including myocardial infarction (MI) and stroke are often diagnosed in patients with abdominal aortic aneurysm (AAA). However, little has been reported regarding the incidence.Patients with AAA were selected from the National Health Insurance system in South Korea between 2009 and 2015. A total of 10,822 participants with a new diagnosis of AAA were included. Propensity score matching by age and sex with patients in whom AAA was not diagnosed was used to select the control group of 32,466 participants. Primary endpoints included the diagnosis of CVD and death. Cox proportional hazard models were used to compare the risk of disease incidence.The incidence of CVD was 16.573 per 1,000 person-years in the AAA group, which was higher than that of the control group's 9.30 per 1,000 person-years. The incidence of MI (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.479-1.953), stroke (HR, 1.629; 95% CI, 1.443-1.839), and CVD (HR, 1.672; 95% CI, 1.522-1.835) was significantly higher in patients with AAA. Mortality rate was also elevated in the AAA group (HR, 2.544; 95% CI, 2.377-2.722).The incidence of CVD was significantly more frequent in patients with AAA. The AAA group had consistently higher risks regarding CVD and mortality than the control group.
Patients with CKD can exhibit hypercoagulability, which might be caused by reduced renal function per se. Both HD and PD can aggravate the prothrombotic tendency of patients with CKD via different mechanisms. Most thrombophilic factors in patients with CKD were corrected after KT.
Postoperative bleeding after ABOi KT was difficult to control and increased the risk of immediate graft loss (p = 0.015). Our results suggest that changes in coagulability associated with uremia and plasmapheresis may increase the risk of bleeding after ABOi KT.
Congenital anomalies of the inferior vena cava (IVC) are rare but important problems in living donors for kidney transplantation, especially in cases of a short left renal vein and accompanying vascular and urological anatomic variations. However, the clinical impacts of IVC anomalies in deceased donors have yet to be reported. The unexpected presence of an IVC in an unusual position poses challenges to surgeons and increases the risk of bleeding during organ removal. Accompanying vascular variations can cause unexpected bleeding and injury and therefore technical complications in procurement and subsequent implantation. During cold perfusion, inadequate venous drainage or insufficient cooling can induce graft damage. Our cases highlight the need for all transplant surgeons to confirm the anatomy of the aorta, IVC, and major vessels early in the surgical procedure and, should an anomaly be detected, know how to manage the problem.
PurposeWe investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI).MethodsBetween February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38).ResultsThe incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024).ConclusionAllografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
