Switching from risperidone to paliperidone palmitate in schizophrenia: Changes in prolactin levels and sexual function

The purpose of this study was to evaluate the outcome of t-Branch (Cook Medical, Bloomington, Ind) stent graft for the treatment of thoracoabdominal and pararenal aortic aneurysms in patients who had previous infrarenal aortic repair.A retrospective two-center study was undertaken. All consecutive patients who underwent endovascular repair using t-Branch stent graft after previous infrarenal aortic repair between January 2010 and August 2018 were included. Demographics, past medical history, cardiovascular risk factors, and intraoperative and perioperative details were recorded. Technical success and early (30-day) mortality, morbidity, target vessel patency, and presence of endoleak were analyzed. During the first year of follow-up, survival, freedom from reintervention, and patency rates were recorded.There were 32 patients (mean age, 74 ± 7 years; 81% male) included in the study; 24 (75%) patients had prior open surgical repair, and 8 (25%) patients had undergone standard endovascular aneurysm repair. The index operation was performed 9 ± 5 years earlier, including 10 ± 5 years for open surgical repair and 8 ± 6 years for endovascular aortic repair. The indication was progression of the disease in 26 patients (81%) and type IA endoleak in 6 patients (19%). The total number of target vessels incorporated was 117 arteries (3.8 ± 0.6 target vessels per patient). Eleven patients had only three vessels incorporated; celiac trunk was occluded in three patients, and eight patients had one functioning kidney. Technical success rate was 97% (31/32). There was a single technical failure in one patient who had a type IA endoleak after endovascular repair with suprarenal fixation. The stenotic right renal artery was not catheterized at the initial procedure, and retrograde access was achieved through a right subcostal incision 3 days later with successful completion of the repair. Early mortality rate was 13%, and spinal cord ischemia rate was 22% (7/32); four patients had permanent and three had transient neurologic deficits. Early target vessel patency was 100%, and the rate of any endoleak was 9% (3/32); two patients had type II endoleaks and one patient had type III endoleak. The mean follow-up was 5.4 ± 5.9 months. The cumulative survival rate was 82% and 73% at 6 and 12 months, respectively. The freedom from aorta-related mortality was 92% at 6 and 12 months. The cumulative freedom from reintervention during follow-up was 90% at 6 and 12 months. The overall target vessel patency rate was 100% and 97.5% at 6 and 12 months, respectively.The use of t-Branch off-the-shelf stent graft for the treatment of aortic disease in patients who had previous infrarenal aortic repair appears to be feasible, with acceptable early outcomes in terms of morbidity and mortality.
