OBJECTIVE: To review the physiology of uteroplacental arterial development and normal postpartum involution, and to present the characteristic clinical and histopathologic features of subinvolution. [ncbi.nlm.nih.gov]

Treatment
If you have atony of the uterus, you’ll need immediate treatment to help stop the bleeding and to replace the lost blood. Postpartum hemorrhage can be very serious. However, early detection and treatment can lead to a full recovery. [healthline.com]

What is subinvolution of placental sites?
Subinvolution of placental sites (SPSs) is a rare but severe cause of secondary postpartum haemorrhage (PPH). SPS is characterised by the abnormal persistence of large, dilated, superficially modified spiral arteries in the absence of retained products of conception. It is an important cause of morbidity and mortality of young women.
When do extravillous cytotrophoblasts invade the spiral arteries?
From early gestation (6–9 weeks), extravillous cytotrophoblasts invade the decidual part of the maternal spiral arteries, replacing the endothelium and it is completed in second trimester when the endothelial lining of the artery is completely replaced.
