This study aimed to document the prevalence and intraoperative characteristics of renovascular variations encountered during PaLA, and to describe their management through detailed photographic documentation.  \nMethods This retrospective single-center observational study included 42 patients with gynecologic malignancies (24 endometrial, 16 ovarian, 2 cervical cancers) who underwent PaLA at Ankara, Türkiye, between February 2024 and February 2025. Procedures were performed laparoscopically (n = 20, 47 . 6%) or via laparotomy (n = 22, 52 .4%) . Patients underwent preoperative contrast-enhanced abdominal CT (slice thickness ≤ 3 mm) . Renovascular variations were identified intraoperatively, photographed, and classified anatomically.  \nResults Renovascular variations were identified in 9 patients (21 .4%) . Inferior polar renal arteries occurred in 5 patients (11 . 9%): 2 bilateral, 3 unilateral right-sided. Retroaortic left renal vein was encountered in 4 patients (9 . 5%) . Preoperative imaging identified variations in 8 of 9 cases (88 . 9%), with one small-caliber artery missed on imaging. No vascular injuries occurred in cases with recognized variations. All laparoscopic cases with variations (n = 4) were completed without conversion.  \nConclusion Renovascular variations occurred in one-fifth of patients undergoing PaLA in this series. While preoperative imaging identified most variations, intraoperative vigilance remains essential. With careful surgical technique and anatomical awareness, these variations can be safely managed, though the small sample size limits generalizability. This series provides educational documentation for gynecologic oncologists.  \nKeywords Gynecologic oncology, Paraaortic lymphadenectomy, Polar artery, Retroaortic vein, Vascular variations  \n*Correspondence:  \nÖzgün Ceylan  \n[ozguncyln@hotmail.com](ozguncyln@hotmail.com)  \n1Department of Gynecologic Oncology, Etlik City Hospital, Ankara, Turkey 2Güvenevler Mah.
