“…One patient had infective colitis with Clostridium difficile toxin and underwent medication therapy (Table III). Due to sufficient diameter of the splenic artery (24), long-term patency of arterial reconstruction was confirmed on contrast-enhanced MDCT performed every three months in all patients. Longterm patency of the reconstructed portal vein was also confirmed in all patients Survival.…”

Background/Aim: The potential benefits of pancreatectomy with major arterial resection have been studied in the past, but findings remain controversial. Pancreatic neck/body cancer (PNBC) involving arteries frequently requires combined resection of the pancreas, artery and portal vein. Patients and Methods: Nine prospectively-registered consecutive patients with PNBC were enrolled, all underwent pancreatoduodenectomy with common hepatic artery en-bloc resection (PD-CHAR). We investigated the safety of PD-CHAR by blood flow evaluation with intraoperative indocyanine green fluorescence imaging in reconstructed vessels/organs. Results: Among patients who underwent PD-CHAR, there was no severe morbidity. Artery/portal vein combined resection and reconstruction was performed in all patients. Four (44%) patients had pathological positivity for cancer cell invasion into the nerve plexus of artery at the site of radiographic artery involvement, although one (11%) was diagnosed with pathological artery involvement. Conclusion: PD-CHAR following neoadjuvant therapy might be feasible for PNBC without severe postoperative complications. Survival benefits in PNBC should be confirmed in further studies.

“…There are three main types of trajectories: straight, sinuous and spiral [ 10 ]. One or more loops are observed in up to 83–86% of spleens [ 11 , 12 ]. It is assumed that tortuosity increases with age.…”

“…The authors suggested that this is due to the peculiarity of the influence of female sex hormones on the walls of blood vessels [ 15 ]. However, Brinkman and coworkers did not find any relationship between splenic artery loops and age or sex but determined that the length of the artery in contact with the pancreas decreased with age [ 12 ]. Michels suggested that the artery is straight in infants and children, minimally tortuous in middle age, and markedly tortuous in the elderly.…”

Background: Precise knowledge of the topographic features of the splenic artery and its branches in the hilum region is of practical interest due to the various interventions on the vessels of the spleen. Materials and methods: The anatomy of the spleen was studied by means of macroscopic dissection on 330 organ complexes, which were carefully documented and analyzed statistically. Results: The analysis of the splenic artery trajectory led to identification of four types: straight (43.03%), sinusoidal (27.58%), serpentine (20.91%) and alternating (8.48%). To assess the relation between the trajectory of the splenic artery and its branches we performed a chi square test. Sinuous or serpentine trajectory was associated with the presence of long splenic artery branches (dorsal pancreatic artery or the great pancreatic artery), X2 (2, N = 330) = 12.85, p = 0.001. The artery was located suprapancreatic in 70.30% of cases, anteropancreatic in 4.55%, the vessel had an intrapancreatic course in 14.85% and in 10.00% of cases the artery was located retropancreatic. The presence of inferior polar arteries was associated with a longer pancreas (Spearman’s correlation; r = 0.37; p = 0.037). In a multiple regression analysis, inferior polar arteries predicted the length of the pancreas although only a small number of cases could be explained by this model (R2 = 0.127, Adjusted R2 = 0.098; Betta = 0.357; t(330) = 2.091; p = 0.045). There were 30 (9.09%) cases of accessory spleens. Conclusions: The arterial supply of the spleen is highly variable in its trajectory, terminal branches, and relation to other organs. The splenic artery tends to be sinuous or serpentine in zones when a large artery branches off (e.g., the dorsal pancreatic or greater pancreatic artery). Multiple short branches tend to stabilize the trajectory of the splenic artery. Inferior polar arteries and accessory spleens contribute to the length of the pancreas, most likely due to increased vascular supply to the tail of the gland.

“…Active bleeding, if present, was managed by additional hyper-selective embolisation. The most commonly used AVP for haemostasis was the 8 mm AVP 4 (13/23, 57%), in keeping with the average size of splenic arteries [20]; the 7 mm AVP 4 was used four times, the 10 mm AVP II three times, and the 12 mm AVP II three times.…”

Our objective was to investigate the indications, effectiveness, and safety of Amplatzer™ Vascular Plugs (AVPs) in clinical practice. To retrospectively identify patients managed with AVPs at the Dijon University Hospital between January 2011 and April 2021, we searched materials vigilance registries and procedure reports. The 110 identified patients underwent 111 procedures with delivery of 202 AVPs into 118 vessels; 84% of the procedures were performed by radiologists with over 10 years’ experience and 67% were scheduled. Varicocele, haemostasis, pelvic varicose veins, and arterio-venous dialysis fistulas accounted for 69% of procedures. The technical and clinical success rates were 99% and 97%, respectively. The single major complication was AVP migration in a high-flow internal iliac vein, with no residual abnormalities after successful device retrieval. Several AVPs and/or concomitant injection of coils or liquid agents were used in 80% of cases. The use of AVPs alone occurred chiefly for splenic artery embolisation in trauma patients and for collateral vein occlusion in dysfunctional arterio-venous dialysis fistulas. No cases of recanalisation occurred during the 19 ± 29 month follow-ups. Based on their good safety and effectiveness profile, AVPs deserve to be part of the therapeutic armamentarium of every interventional radiologist.
