Surgical treatment of visceral and renal abdominal artery aneurysms of various etiology

Visceral artery aneurysms are detected when complications occur or accidentally during examination for other diseases gastrointestinal tract, aimed at determining the functional significance. Over the past 10 years, we have observed 31 patients with abdominal visceral artery aneurysms, 10 patients had renal aneurysms, 15 had splenic arteries, hepatic artery and pancreatoduodenal artery aneurysms – in one case. The combination of aneurysms – in 2 cases: in one case – the renal artery with the splenic artery, in the other – the renal artery and the abdominal trunk. The patients ranged in age from 24 to 78 years, the average age is 43±6.5. Previously, infection was considered the most common cause of splenic artery aneurysms in 10 cases, with most patients complaining of fever, abdominal pain and a pulsating mass in the abdomen. And two patients with splenic artery aneurysm noted abdominal trauma. 3 had atherosclerotic changes. The causes of renal artery aneurysms are atherosclerosis in 6 cases, fibromuscular dysplasia in 2 cases, and Nonspecific aortoarteritis in 2 cases. Also, atherosclerotic etiology is present in aneurysms of the external iliac arteries aneurysms. Reconstructions on hepatobiliary aneurysms were performed in 6 (20%) cases, in 5 cases - resection with end-to-end anastomosis and in 2 cases - resection of splenic artery aneurysm, resection of splenic artery aneurysms with autovenous patch, clipping of splenic artery aneurysms – in 2 cases (6.5%), endovascular techniques were applied in 18 cases (58%). In 2 cases, nephroectomy was performed due to the spread of the aneurysm into the kidney gate and the lack of conditions for reconstruction. In the immediate and long-term (after 6 months and 3 years) postoperative period, the preservation of organ function in reconstructive and ligating methods of surgical treatment is the same. Signs of ischemia and impairment in the immediate postoperative period were not observed with reconstructive and ligating methods of surgical treatment. The choice of treatment method depends on the severity of the patient’s condition, clinical manifestations, as well as the localization of the aneurysm and its morphology. Preference is given to endovascular techniques, which are not traumatic enough and provide a good long-term result. However, in each case, the patient’s management tactics are individual, the choice of the optimal method of treatment of visceral artery aneurysms is based on data from the entire spectrum of possible diagnostic manipulations.

Simultaneous surgical treatment for esophagogastric junctional cancer and splenic artery aneurysm resection with spleen preservation using fluorescence imaging: a case report

BackgroundRecently, minimally invasive esophagectomy and gastrectomy for esophagogastric junctional (EGJ) cancer using either thoracoscopy or laparoscopy are frequently performed. In the past decade, minimally invasive surgery with laparoscopy for splenic artery aneurysm (SAA) has also been reported. However, patients with both EGJ cancer and SAA are rare.Case presentationA 66-year-old man, who complained of upper abdominal pain, was found to have esophagogastric junctional (EGJ) tumor. He was diagnosed as having Siewert type II adenocarcinoma. In a computed tomography (CT) scan before surgery, a 10-mm aneurysm in the splenic artery was found. Thus, we performed laparo- and thoracoscopic proximal gastrectomy and lower esophagectomy for EGJ cancer and splenic artery aneurysm (SAA) resection with spleen preservation using fluorescence imaging.We confirmed sufficient blood supply to the spleen after surgery with a postoperative CT scan. The blood supply to the spleen was suspected to be from the great pancreatic artery via the pancreas and from the omental branches of the left gastroepiploic artery via the omental artery.ConclusionSimultaneous surgery for EGJ cancer and SAA is rare due to its potential risk, but evaluation of the blood supply for the spleen by using fluorescence imaging can be useful for this procedure.

Endovascular and Surgical Management of Intact Splenic Artery Aneurysm

This study aims to reveal the experience with endovascular and surgical management of intact splenic artery aneurysms in our single center. Between January 2011 and June 2017, 42 patients with intact splenic artery aneurysm were enrolled in this study. Twenty patients undergoing surgical intervention were classified as the surgical group, and 22 patients who received endovascular repair were categorized as the endovascular group. Demographic data, preoperative comorbidities, and anatomical characteristics of aneurysms were collected and analyzed. Details of interventions, perioperative outcomes, and follow-up results were evaluated and compared between the 2 groups. Forty-two patients with a mean age of 53.4±11.6years were enrolled in this study, and 44 aneurysms were repaired. Thirty-nine (92.9%) patients were asymptomatic, and 3 (7.1%) patients were symptomatic. The diameter of splenic artery aneurysms was 3.3±1.6cm, and the shape was mostly saccular. In the surgical group, the common methods used were splenic artery aneurysm resection (9 patients), followed by splenic artery aneurysms resection and splenectomy (6 patients), splenic artery aneurysm resection and arterial reconstruction with end-to-end anastomosis (3 patients), and laparoscopic splenic artery aneurysm resection coexisting with splenectomy (2 patients). In the endovascular group, the exclusive means was embolization with coils. The technical success rates in both open repair and endovascular repair were 100%. The 30-day mortality was nil, and no severe complication was found in the early time except that 1 patient suffered multiple splenic abscess in the endovascular group after embolization. Endovascular repair had significantly shorter surgery time (82.5±27.6 vs 191.9±62.7min, P<0.001) and hospital stay (5.6±3.1 vs 10.8±5.2days, P<0.001) compared with open repair. The median follow-up period in this study was 34.5 (interquartile range 16.8-60.8) months. Two sac reperfusions were detected during the follow-up in the endovascular group, and patients needed new embolization. No late deaths were found in the follow-up period, and the freedom from reintervention in the endovascular group at 1 and 3years postoperatively was 95.5% and 82.4%, respectively. In addition, the freedom from reintervention in the surgical group at both 1 year and 3years postoperatively were 100%. No significant differences were observed in late survival and reintervention between open repair and endovascular repair. Open repair and endovascular repair were equally feasible, safe, and effective for intact splenic artery aneurysm. Endovascular repair is less invasive accompanied with an obvious decrease in surgery time and rapid recovery with a short hospital time.

Application value of the adhesive suspension of left lateral lobe of liver in transumbilical single-port laparoscopic left upper abdominal surgery

Objective To investigate the application value of the adhesive suspension of left lateral lobe of liver in transumbilical single-port laparoscopic left upper abdominal surgery. Methods The retrospective cross-sectional study was conducted. The clinical data of 112 patients who underwent single-port laparoscopic left upper abdominal surgery in the Shengjing Hospital of China Medical University between January 2010 and October 2016 were collected. Patients underwent single-port laparoscopic left upper abdominal surgery, and intraoperative surgical fields were exposed through adhesive suspension of left lateral lobe of liver. Observation indicators: (1) intraoperative situations: surgical completion, surgical procedures, time of liver adhesive suspension, total operation time and intraoperative liver adhesive suspension-related complications; (2) postoperative situations: pre- and post-operative alanine transaminase (ALT) and aspartate transaminase (AST) levels, hospital expenses and duration of hospital stay; (3) follow-up: number of patients with follow-up, follow-up time, complications during follow-up. Follow-up using outpatient examination and telephone interview was performed to detect postoperative complications up to June 2017. Measurement data with normal distribution were represented as ±s. Repeated measurement data were analyzed using the repeated measures ANOVA. Results (1) Intraoperative situations: 112 patients underwent successfully single-port laparoscopic left upper abdominal surgery, without conversion to multi-port surgery or open surgery. Of 112 patients, 30, 23, 13, 11, 11, 10, 3, 3, 3, 3, 1 and 1 underwent radical resection of gastric cancer, partial gastrectomy, esophageal Heller myotomy + Dor fundo-plication, subtotal gastrectomy, resection of body and tail of pancreas, paraoesophageal hiatal hernia repair + fundoplication, total gastrectomy, splenectomy, splenectomy + devascularization, pancreatic tail resection, simple fundoplication and splenic artery aneurysm resection, respectively. Time of liver adhesive suspension and total operation time in 112 patients were respectively (1.4±0.4)minutes and (192.0±91.3) minutes. There was no hepatic laceration, hepatic subcapsular hematoma and other complications. (2) Postoperative situations: of 112 patients, preoperative ALT and AST levels of 6 patients were mildly elevated, postoperative ALT and AST levels in 2 of 6 patients returned to normal, that in 1 of 6 patients were elevated at day 1 postoperatively and returned to normal at day 3 postoperatively, and that in 2 of 6 patients remained mildly elevated at week 1 postoperatively; preoperative ALT and AST levels of 106 patients were normal, ALT and AST levels in 31 of 106 patients were elevated at day 1 postoperatively (that in 28 patients returned to normal within week 1 postoperatively, and that in 3 patients remained mildly elevated), and that in 75 of 106 patients returned to normal. ALT and AST levels of 112 patients were (16±11)U/L, (18±7)U/L before operation and (31±21)U/L, (34±26)U/L at day 1 postoperatively and (19±17)U/L, (19±12)U/L at week 1 postoperatively, respectively, with statistically significant differences in ALT and AST levels before operation and at day 1 postoperatively (F=36.353, 29.792, P 0.05). Hospital expenses, surgery-related expenses and duration of hospital stay were (45 231±20 440)yuan, (23 511±9 609)yuan and (6.0±1.9)days, respectively. (3) Follow-up: 112 patients were followed up for 1.0-3.0 months, with a median time of 1.6 months. During the follow-up, there were no obvious complications. Conclusion Adhesive suspension of left lateral lobe of liver is simple and safe, with satisfactory exposure effects, and it is suitable for the better operative field exposure in single-port laparoscopic left upper abdominal surgery. Key words: Gastric neoplasms; Left lateral lobe of liver; Suspension, adhesive; Left hypochondriac region; Laparoscopy, single-port

Laparoscopic distal pancreatectomy and splenectomy for splenic artery aneurysm

Large splenic artery aneurysms are rare but comprise 60% of all visceral artery aneurysms. Most are found incidentally and rupture in the nonpregnant patient has an approximate 25 to 36% mortality rate. Historically these have been managed with an open surgical approach for resection. We present the case of a 43-year-old man with a recent episode of bacterial endocarditis with an incidental finding of a large 6-cm splenic artery aneurysm. There was noted to be splenic vein occlusion and multiple splenic infarcts versus abscesses on preoperative imaging. There were concerns that this represented a mycotic aneurysm. He underwent laparoscopic en bloc splenic artery aneurysm resection with splenectomy and distal pancreatectomy with preoperative prophylactic balloon catheter placement. His large splenic artery aneurysm was adjacent to the splenic hilum. Due to the splenic vein occlusion, there were large collateral vessels complicating the dissection. Additionally, the aneurysm had dense adhesions to the tail of the pancreas from a desmoplastic reaction. To safely remove the aneurysm, a distal pancreatectomy was included with resection of the spleen. The specimen was successfully removed intact using the laparoscopic approach. The patient had an uneventful recovery and was discharged home on postoperative day 2. Final pathology revealed no evidence of bacterial etiology. Laparoscopic distal pancreatectomy with splenectomy is an appropriate minimally invasive option for the treatment of splenic artery aneurysms. This video demonstrates the technical challenges and management options for successfully completing a distal pancreatectomy and splenectomy in the face of a splenic artery aneurysm.

Infected splenic artery aneurysm with associated splenic abscess formation secondary to bacterial endocarditis: Case report and review of the literature

Infected aneurysms are rare and may present with rupture or sepsis. Surgical treatment is often required to prevent catastrophic sequelae. Bacterial endocarditis is one of the classic causes of infected aneurysm. We present a case of a 6.1-cm infected splenic artery aneurysm secondary to endocarditis. Surgical treatment consisted of aortic and mitral valve replacements, splenic artery aneurysm resection, and splenectomy. We reviewed five other reported infected splenic artery aneurysms in which documented ruptured had occurred in three patients. Because the rate of rupture in these patients appears to be quite high, infected splenic artery aneurysms require prompt treatment.

Laparoscopic resection of splenic artery aneurysms

Laparoscopic techniques used to manage asymptomatic splenic artery aneurysms have been reported infrequently. A laparoscopic splenic artery aneurysm resection was attempted for six consecutive patients. One patient underwent conversion to laparotomy because of a tear in the splenic vein. Among the five successful laparoscopic splenic artery aneurysm resections, the mean estimated blood loss was 37 +/- 12.6 ml, the mean operative time was 187.6 +/- 79.2 min, and the mean postoperative length of hospital stay was 1.8 +/- 1.3 days. The mean time to a clear liquid diet was 5.3 +/- 0.5 h, and the mean time to a regular diet was 1 +/- 0 day. The mean duration of narcotic analgesic use was 5.4 +/- 1.5 days, and the mean time to resumption of regular activities was 12.7 +/- 1.6 days. These cases illustrate the benefit of a laparoscopic approach with brief hospitalizations, early resumption of diet and regular activity, and minimal use of postoperative narcotic analgesics.
