Purpose: To evaluate the caliber of an arterial micro-anastomosis in the young growing animal using a continuous suture technique. Additionally, late morphological changes and blood flows distal to the anastomosis were evaluated.
Methods: Seventy-four Wistar rats were submitted to laparotomy to access the aorta for blood flow measurement. The aorta was sectioned using microsurgery technique and an end-to-end anastomosis with continuous suture. After a period of six months to one year, the anastomosis was checked.
Results: Regarding the size of the aortas, comparing the pre- and postoperative values, there was an increase of 13.33% in adult animals and 25% in young animals, without any difference in the blood flows.
Conclusions: The arteries of young rats show signs of growth at the site of the anastomosis performed with continuous suture.

A deviated nasal septum leads to congestion and headaches. Surgery is the primary treatment, requiring careful postoperative septum positioning to prevent bleeding and hematoma. The study compared this method with nasal packing and traditional nasal septum suturing regarding surgical time, patient pain, nasal obstruction, and bleeding after septoplasty.

This paper explored the protective effect and potential mechanism of Shouhui Tongbian Capsules(SHTB) on cerebral ischemia-reperfusion rat models. Rats were randomly divided into sham surgery group, model group, low-dose SHTB group(0.2 g·kg~(-1)·d~(-1)), high-dose SHTB group(SHTB g·kg~(-1)·d~(-1)), and an edaravone positive drug group(5.

Internal herniation through the foramen of Winslow (FoW) is a rare, life-threatening diagnosis. We present a case of intestinal obstruction due to herniation of the ileum, cecum, appendix, and ascending colon through the FoW. We reduced the herniation using a small colotomy and preserved the entirety of the bowel.
