Summary
This summary is machine-generated.Splenic vein dilatation is a key risk factor for portal vein thrombosis (PVT) after simultaneous hepatectomy and splenectomy (HS). PVT commonly affects the intrahepatic portal vein, requiring vigilance in patients with dilated splenic veins undergoing HS.
Area Of Science
- Hepatobiliary Surgery
- Vascular Surgery
- Surgical Complications
Background
- Postoperative portal vein thrombosis (PVT) is a known complication following splenectomy.
- Limited research exists on PVT incidence and risk factors after simultaneous hepatectomy and splenectomy (HS).
Purpose Of The Study
- To investigate the risk factors associated with PVT after HS.
- To characterize the presentation of PVT in patients undergoing HS.
Main Methods
- A retrospective observational study of 102 patients who underwent HS.
- Analysis of contrast-enhanced CT scans 1 week post-surgery to detect PVT.
- Comparison of pre- and intraoperative parameters between patients with and without PVT.
Main Results
- The incidence of PVT after HS was 28.4%, higher in patients with liver cirrhosis (32.9%).
- Intrahepatic portal vein thrombosis was the most common type (72.4%).
- Preoperative splenic vein dilatation was identified as an independent risk factor for PVT (OR: 1.53, P=0.003).
Conclusions
- Splenic vein dilatation is a significant independent risk factor for PVT following HS.
- PVT after HS predominantly involves the intrahepatic portal vein.
- Close monitoring for intrahepatic PVT is crucial in HS patients with preoperative splenic vein dilatation.
