Does surgical repair using bicaval cannulation with unsnared IVC improve surgical exposure and prevent complications in patients with inferior sinus venosus defects?
Bicaval cannulation with an unsnared IVC improves surgical exposure and helps prevent iatrogenic IVC-left atrial shunts during the repair of inferior sinus venosus defects.
May support unsnared IVC cannulation for inferior sinus venosus defect repair; leaves open need for comparative trials before routine adoption.
BACKGROUND: Inferior sinus venosus defects (SVD) are very rare and difficult to image from transthoracic echocardiography. Surgical errors were occasionally reported in the repair of inferior SVDs. RESULTS: The authors have operated on 12 inferior SVD patients using bicaval cannulation with unsnared inferior vena cava (IVC) and proved successful. CONCLUSION: This technique guaranteed a better exposure of surgical field and facilitate identifying the anatomical relationship between lower part of the SVD and IVC orifice, thus avoiding postoperative IVC - left atrial shunt and other surgical mistakes.

Lin et al. (2015) conducted an observational in Inferior sinus venosus defects (n=12). Bicaval cannulation with unsnared inferior vena cava was evaluated on Surgical success and avoidance of postoperative IVC-left atrial shunt. Surgical repair of inferior sinus venosus defects using bicaval cannulation with an unsnared inferior vena cava was successful in 12 patients, providing better exposure and avoiding complications.
