Intestinal obstruction induced by portal vein thrombosis in a female undergoing oral contraceptive therapy: a case report with comprehensive review.

INTRODUCTION

Portal vein thrombosis (PVT) is a rare medical condition that obstructs blood flow in the portal vein, with cirrhosis as a common predisposing factor. However, its association with oral contraceptive pills (OCPs), particularly with progestins, remains inadequately explored. This case report aims to contribute to this understanding, focusing on the rare presentation of PVT-induced intestinal obstruction in a female on prolonged OCP therapy.

CASE PRESENTATION: A 45-year-old female presented with severe abdominal pain, vomiting, and constipation. Diagnosis revealed PVT-induced intestinal obstruction, an exceptionally rare occurrence in the context of prolonged OCP therapy. The patient's symptoms improved with conservative management, including rivaroxaban, highlighting the crucial role of early intervention.

DISCUSSION: This case brings attention to the limited literature exploring the link between OCPs and PVT. Despite the generally safe reputation of OCPs, they can induce pro-thrombotic conditions, emphasizing the need for heightened clinical awareness. In this case, the rarity of intestinal obstruction in PVT, compounded by the absence of common risk factors, underscores the diagnostic challenges associated with such presentations.

CONCLUSION

PVT-induced intestinal obstruction in a patient on prolonged OCP therapy is exceptionally rare, emphasizing the necessity for multidisciplinary management. It provides crucial insights into suspecting, identifying, and treating this uncommon complication in non-cirrhotic individuals, contributing to the limited existing literature on the subject.
