It is a retroperitoneal structure and plays a key role in topographic and clinical anatomy, especially in conditions like Superior Mesenteric Artery (SMA) Syndrome 💥. The anterior relations of the 3rd part of the duodenum are extremely high-yield and include: • Superior Mesenteric Artery (SMA) — passes anteriorly over this segment and may compress it, leading to SMA syndrome in cases of weight loss or spinal deformity 🩸⚠️ • Superior Mesenteric Vein (SMV) — travels alongside the SMA and contributes to venous drainage of midgut 🌐 • Root of the mesentery — containing lymphatics, fat, vessels, and nerves, lies anterior to the duodenum 🧬 • Jejunal loops — may overlap anteriorly in thin individuals or in certain surgical views 🔁 • Peritoneum — covers the anterior surface as part of the posterior abdominal wall 💡 Understanding these relations is crucial in both diagnosis and surgery—particularly for vascular surgeons, gastrointestinal specialists, and radiologists. Anterior compression by the SMA can result in postprandial pain, vomiting, and weight loss, classic features of SMA syndrome. #DuodenumAnatomy #ThirdPartDuodenum #AnteriorRelations #SMASyndrome #NEETPG2025 #USMLEStep1 #FMGE2025 #HighYieldAnatomy #RetroperitonealAnatomy #MBBSLectures #TopographicAnatomy #SMACompression #MedicalEducation #DoctorInTheMaking #ClinicalAnatomy #CadavericDissection #AnatomyMadeEasy #GIAnatomy #ExamCracker #MedicalStudents
