Evaluation of the hepatic artery anastomosis by intraoperative sonography with high‐frequency transducer in right‐lobe graft living donor liver transplantation

Abstract

IOUS with high-frequency transducer is a useful method to make an early diagnosis of HA complications of LDLT with RLG.

Evaluation of Pediatric Liver Transplantation-Related Artery Complications Using Intra-Operative Multi-Parameter Ultrasonography

“…The values reported by different transplantation centers wary widely, but are generally 7.2% to 14.3% [6,7]. Insufficient arterial blood flow may cause transplant ischemia and dysfunction, biliary necrosis, biliary fistula, bile duct abscess, and even hepatic failure in severe cases [8]. All these seriously affect the survival of the transplants and recipients.…”

“…The vast majority of scholars agree that color Doppler is the only preferred and effective examination method, and the conventional color Doppler imaging of the vessels can achieve the early detection of all vascular complications, rarely using CT or angiography [8]. Because large medical devices are inconvenient to move, and the conventional color Doppler ultrasonography might show overflowing of blood flow signal, the intraoperative imaging is completed only by ultrasonography, and small arteries cannot be measured accurately.…”

Living Donor Liver Transplantation

“…Following artery anastomosis, hepatic and portal vein artery flows must be assessed through Doppler US. This approach particularly allows assessing morphological features of quite small hepatic arteries besides their qualitative and quantitative flow patterns and also solves artery problems intraoperatively (29). Biliary anastomosis is conducted through duct-to-duct technique and individual sutures as far as possible.…”

Visibility of the graft hepatic artery using superb microvascular imaging in liver transplantation recipients: initial experience

“…Doppler ultrasonography (US) is a primary surveillance method for detection of HA complications in LT recipients and it is easy, fast, and can be performed at bed-side without severe side effects for the patients (4,5).…”

“…Doppler ultrasonography (US) is a primary surveillance method for detection of HA complications in LT recipients and it is easy, fast, and can be performed at bed-side without severe side effects for the patients (4,5). However, conventional color Doppler imaging (CDI) suffers from technical limitations and investigators reported that CDI was unable to depict flow of the patent HA in 1.8–4.4% of LT recipients (6,7).…”
