Purpose: The objective of this study is to describe a novel method for creating a distal landing zone for thoracic endovascular aortic repair (TEVAR) in chronic aortic dissection. The technique is described in a patient with prior total arch and descending aortic replacement, with false lumen expansion. Technique: A cheese-wire endovascular septotomy was desired to create a single lumen above the celiac axis. To avoid dividing the septum caudally across the visceral segment, we performed a modified septotomy in a cephalad direction. Stiff wires were passed into the prior surgical graft, through true lumen on the right and false lumen on the left. An additional wire was passed across an existing fenestration at the level of the celiac axis, and snared and externalized. 7F Ansel sheaths were advanced and positioned tip-to-tip at the fenestration. Using the stiff wires as tracks, the through-wire was pushed cephalad to endovascularly cut the septum. Angiogram demonstrated successful septotomy, and TEVAR was performed to just above the celiac with successful aneurysm exclusion and no endoleak or retrograde false lumen perfusion. Follow-up computed tomography angiogram (CTA) showed continued exclusion without false lumen perfusion. Conclusions: This novel modification in a reverse direction provides an alternative method for endovascular septotomy, when traditional septotomy may threaten the visceral vessels.

Abstract Background Intraoperative bleeding from the celiac axis (CA) can occur during pancreatic surgery, and appropriate management is essential to avoid critical complications. Here, we have reported a case that was managed with supraceliac aortic cross-clamping (SAC) for arterial bleeding from the CA during pancreatic surgery. Case presentation A 70-year-old man was diagnosed with pancreatic cancer located in the pancreatic head and body. Preoperative computed tomography showed a stricture at the root of the CA, which may have been caused by a median arcuate ligament. Pancreaticoduodenectomy with division of the median arcuate ligament was scheduled. Uncontrollable bleeding from the root of the CA was observed during surgery. The bleeding was controlled by performing SAC, and a defect in the CA was confirmed. Arterial wall repair was successfully performed under temporal blood control using SAC. The aortic clamp time was 2 min and 51 s, and the intraoperative blood loss was 480 ml. Conclusions Although SAC is primarily a procedure for ruptured abdominal aortic aneurysm, it can be useful for the management of CA injuries during pancreatic surgery.

The paper "Laparoscopic treatment of the rare median arcuate ligament syndrome - mid-term follow-up" is important because the results of treatment are based not only on the subjective feelings of patients, but also on objective imaging tests, which is not observed in the previously published works on this topic. SUMMARY Introduction Median arcuate ligament syndrome [MALS] is a rare cause of chronic epigastric pain. The presentation might be unclear and non-specific. Diagnosing the syndrome requires interdisciplinary methods and specialists. Treatments consist of celiac axis release performed laparoscopically or robotically, and intraluminal stenting. The aim of the study was to report the medium-term postoperative follow-up results for four patients with MALS. Material and methods We performed 5 laparoscopic celiac axis releases in patients with MALS in our department in 2018. We included 4 patients in this study and all patients were admitted 16-23 months after the surgery for computed tomography angiography. Results Patients constituted 4 women aged 28-63 years with a mean body mass index of 22.4 kg/m2. The diagnosis of MALS was confirmed by computed tomography angiography, which showed severe (> 70%) narrowing of the celiac axis. Patients underwent laparoscopic celiac axis release, and all patients were discharged on the first postoperative day with no postoperative complications. Patients improved quality of life and complete relief of symptoms. Follow-up computed tomography angiography confirmed full decompression of the celiac axis in all four patients, with no stenosis caused by scarification of the celiac axis. Conclusions Laparoscopy is a valuable and safe method to treat patients with MALS. Keywords: Dunbar syndrome, median arcuate ligament syndrome, laparoscopy, MALS, digestive surgery

Abstract Background Pancreaticoduodenal artery aneurysms (PDAAs) are rare visceral aneurysms, and prompt intervention/treatment of all PDAAs is recommended at the time of diagnosis to avoid rupture of aneurysms. Herein, we report two cases of PDAA caused by the median arcuate ligament syndrome, treated with surgical revascularization by aortosplenic bypass followed by coil embolization. Case presentation Case 1 A 54-year-old woman presented with a chief complaint of severe epigastralgia and was diagnosed with two large fusiform inferior PDAAs and celiac axis occlusion. To preserve the blood flow of the pancreatic head, duodenum, liver, and spleen, we performed elective surgery to release the MAL along with aortosplenic bypass. At 6 days postoperatively, transcatheter arterial embolization was performed. At the 8-year 6-month follow-up observation, no recurrent perfusion of the embolized PDAAs or rupture had occurred, including the non-embolized small PDAA, and the bypass graft had excellent patency. Case 2 A 39-year-old man who had been in good health was found to have a PDAA with celiac stenosis during a medical checkup. Computed tomography and superior mesenteric arteriography showed severe celiac axis stenosis and a markedly dilated pancreatic arcade with a large saccular PDAA. To preserve the blood flow of the pancreatic arcade, we performed elective surgery to release the MAL along with aortosplenic bypass. At 9 days postoperatively, transcatheter arterial embolization was performed. At the 6-year 7-month follow-up observation, no recurrent perfusion or rupture of the PDAA had occurred, and the bypass graft had excellent patency. Conclusion Combined treatment with bypass surgery and coil embolization can be an effective option for the treatment of PDAAs associated with celiac axis occlusion or severe stenosis.

A 61-year-old man presented with retroperitoneal hemorrhage caused by an aneurysm rupture of the pancreaticoduodenal arcade (PDA), and acute celiac artery dissection distal to celiac axis stenosis. Owing to the gradual growth of the false lumen, we planned to deploy a stent to the celiac artery dissection and embolize the PDA aneurysm. Prior to stent placement, we assessed the acute celiac artery dissection distal to the stenosis using four-dimensional computed tomography (CT) angiography through expiration/inspiration/expiration cycle. We diagnosed median arcuate ligament syndrome considering that the celiac axis showed a hooked narrowing at end-expiration, and the compression decreased at end-inspiration. Additionally, the true lumen distal to the stretched axis dilated in the inspiration phase. Therefore, we could advance a catheter into the true lumen during inspiration and successfully deploy a stent. Subsequently, laparoscopic median arcuate ligament release was performed after the stent deployment. A postoperative CT scan showed good patency in the stent, with disappearance of the blood filling the false lumen and with reduced celiac axis stenosis.

The review presents an analysis of the literature and our own data on the use of intra-arterial chemotherapy in pancreatic cancer. It is concluded that transcatheter arterial administration of cytostatics is a relatively safe and effective method of treatment. Combination of celiac axis infusion with arterial chemoembolization, as well as infusion with radiotherapy increase the survival. Neoand adjuvant arterial chemotherapy improves the results of pancreatic surgery. The use of new locoregional chemotherapy regimens is promising and requires further study.
