Actual (reported)This retrospective, single-centre observational study evaluates perioperative determinants and clinical outcomes of postoperative acute kidney injury (AKI) in patients undergoing pulmonary endarterectomy (PEA) between 2018 and 2020. AKI is classified according to KDIGO 2012 criteria using both serum creatinine changes and urine output over 48 hours. Preoperative, intraoperative and postoperative variables are assessed using multivariable logistic regression. Intraoperative time variables - including extracorporeal circulation (ECC) duration, deep hypothermic circulatory arrest (DHCA) duration and aortic cross-clamp time - are entered simultaneously to identify which component independently captures renal risk. The study also evaluates a parsimonious multivariable risk-stratification model based on routinely available perioperative data. Secondary outcomes include 30-day mortality, intensive care unit stay, hospital length of stay and renal replacement therapy requirement. Findings from this study may provide insights into perioperative risk stratification and renal monitoring strategies in patients undergoing pulmonary endarterectomy.

Actual (reported)Incidence and Perioperative Determinants of Postoperative Acute Kidney Injury
The primary outcome is the occurrence of postoperative acute kidney injury (AKI) within 48 hours of surgery, defined according to KDIGO 2012 criteria using both serum creatinine changes from baseline and hourly urine output. AKI is analysed as a binary variable (yes/no) and further classified by severity stage (1, 2 or 3). Independent perioperative determinants of AKI - including extracorporeal circulation duration, deep hypothermic circulatory arrest duration, aortic cross-clamp time, age and early postoperative albumin - are assessed using multivariable logistic regression.
up to 48 hours, postoperatively
Severity of Acute Kidney Injury According to KDIGO Staging
up to 48 hours, postoperatively
This study will include adult patients aged 18 to 85 years who underwent pulmonary endarterectomy at the Cardiothoracic Surgery Unit of Kosuyolu Kartal Heart Training and Research Hospital (Kosuyolu KHTRH), a single tertiary referral center in Istanbul, Turkey, between January 1, 2018, and December 31, 2020. Patients meeting the inclusion criteria will have complete perioperative data available, including total circulatory arrest duration and postoperative renal function parameters. Individuals younger than 18 years of age and pregnant women at the time of surgery will be excluded.
