Serotonin [5-hydroxytryptamine (5-HT)] causes relaxation of the isolated superior mesenteric vein, a splanchnic blood vessel, through activation of the 5-HT7 receptor. As part of studies designed to identify the mechanism(s) through which chronic (≥24 h) infusion of 5-HT lowers blood pressure, we tested the hypothesis that 5-HT causes in vitro and in vivo splanchnic venodilation that is 5-HT7 receptor dependent. In tissue baths for measurement of isometric contraction, the portal vein and abdominal inferior vena cava relaxed to 5-HT and the 5-HT1/7 receptor agonist 5-carboxamidotryptamine; relaxation was abolished by the 5-HT7 receptor antagonist SB-269970. Western blot analyses showed that the abdominal inferior vena cava and portal vein express 5-HT7 receptor protein. In contrast, the thoracic vena cava, outside the splanchnic circulation, did not relax to serotonergic agonists and exhibited minimal expression of the 5-HT7 receptor. Male Sprague-Dawley rats with chronically implanted radiotelemetry transmitters underwent repeated ultrasound imaging of abdominal vessels. After baseline imaging, minipumps containing vehicle (saline) or 5-HT (25 μg·kg−1·min−1) were implanted. Twenty-four hours later, venous diameters were increased in rats with 5-HT-infusion (percent increase from baseline: superior mesenteric vein, 17.5 ± 1.9; portal vein, 17.7 ± 1.8; and abdominal inferior vena cava, 46.9 ± 8.0) while arterial pressure was decreased (~13 mmHg). Measures returned to baseline after infusion termination. In a separate group of animals, treatment with SB-269970 (3 mg/kg iv) prevented the splanchnic venodilation and fall in blood pressure during 24 h of 5-HT infusion. Thus, 5-HT causes 5-HT7 receptor-dependent splanchnic venous dilation associated with a fall in blood pressure. NEW & NOTEWORTHY This research is noteworthy because it combines and links, through the 5-HT7 receptor, an in vitro observation (venorelaxation) with in vivo events (venodilation and fall in blood pressure). This supports the idea that splanchnic venodilation plays a role in blood pressure regulation.

Laparoscopic Assisted

Portal vein thrombosis is a rare but well-reported complication after laparoscopic surgery. We present a case of portomesenteric venous thrombosis that occurred 8 days after a laparoscopic-assisted right hemicolectomy. Systemic anticoagulation failed to improve symptoms. The early postoperative state precluded the use of transarterial thrombolytic therapy. Transjugular intra-hepatic catheter-directed infusion of urokinase into the superior mesenteric vein resulted in clearance of thrombus and resolution of symptoms. The published data on laparoscopy-induced splanchnic venous thrombosis and transjugular intrahepatic intramesenteric thrombolysis are discussed.

End Stage

The incidence of cirrhosis, the end stage for many liver diseases, is rising and with it the need for better understanding of the progression of the disease and diagnostic techniques. The authors have noted that liver disease occurs preferentially in the right side of the liver which is the largest lobe. One hypothesis is that this is due to the composition of the blood that supplies the right lobe. The liver is fed by both the hepatic artery and the portal vein with the portal vein contributing about 80% of the blood supply. The portal vein (PV) is supplied by the superior mesenteric vein (SMV), which drains blood from the digestive track, and the splenic vein (SV), which drains blood from the spleen. Since the blood in the SMV is coming from the digestive track, it carries toxins and items absorbed during digestion. Toxins such as alcohol are known to damage the liver. Thus, our hypothesis is that the majority of the SMV flow feeds into the right portal vein and ultimately the right lobe of the liver. This study seeks to assess the validity of our hypothesis in four subjects by creating subject specific models in two normal subjects and two patients and using computational fluid dynamics (CFD) to calculate the SMV contribution to the right portal vein.

482 Background: Combined portal vein and/or superior mesenteric vein (PV/SMV) resection with pancreatectomy sometimes leads to prolonged survival for patients with periampullary tumors. In this study, we evaluated outcomes of patients with PV/SMV reconstruction, and we considered indications for the use of a graft during this procedure. Methods: We performed PV/SMV resection with pancreatectomy in 128 patients with periampullary tumors, including 14 using grafts. Short and long-term outcomes associated with PV/SMV reconstruction and harvesting venous grafts and reconstructed PV/SMV patency during follow-up were assessed. Results: Of the 128 patients with periampullary tumors, 5 underwent total pancreatectomy, 99 pancreaticoduodenectomy, and 24 distal pancreatectomy. In the 14 patients who underwent PV/SMV reconstruction with grafts, the grafts were harvested from external iliac vein in 10 patients and internal jugular vein in the other 4. Five patients (3.9%) had intraoperative or postoperative acute thrombus or stenosis of reconstructed PV/SMV after direct end-to-end anastomosis. However, PV/SMV patency was excellent after reconstruction using grafts. Among 228 patients with common pancreatic cancer, there were no significant differences in overall survival (OS) between the patients with PV/SMV resection (n=99) and without PV/SMV resection (n=206) (P=0.354), although the lymph node metastasis rates in the patients with PV/SMV resection were higher than those without PV/SMV resection (78.8 vs. 64.6%, P=0.012). Furthermore, the tumor size in the patients with the use of a graft was larger than that without a graft (Mean size; 40.5 vs. 29.3 mm, P=0.047), and the R0 rates and OS were not different between the patients with and without a graft (R0 rates; 50 vs. 73%, P=0.129 and OS; 23.4 vs. 16.6 months, P=0.323). Conclusions: Depending on the length and/or position of the removed PV/SMV segment, an interposed graft may be required for reconstruction in some patients.
