[Hemodynamics of portal system using color ultrasonography and direct pressure measurement before and after pericardial devascularization].
Controlled study on the portal hemodynamics was carried out before and after pericardial devascularization in 23 patients with portal hypertension. Color ultrasonography detected LGV in 87% of the patients, total prehepatic shunt volume was larger than 46.92%, That through SV more than 15. 48%, and LGV about 15.97%. Hence the total volume shunted through gastrosplenic region was more than 31.45%. Postoperative FPP was significantly decreased (P < 0.05) and SOPP and gastris wall venous pressure increased (P < 0.01). Postoperative PVF did not change significantly. When the ratio of SAV to SVF was less than 1.0, postoperative PVF was significantly increased (P < 0.05). Shunt surgery is the treatment of choice. In the case when the ratio in larger than 1.0, PVF may, decrease (P < 0.01); Patients should receive devascularization. When SVF plus SMVF is greater than PVF, patients should be operated on only with splenectomy or devascularization.
