Infrarenal aorta as the donor site for bypasses to the superior mesenteric artery for chronic mesenteric ischemia: A prospective clinical series of 24 patients

Background. Treatment of symptomatic, chronic mesenteric ischemia is indicated to relieve symptoms and prevent acute ischemia and death. Current therapeutic options include endovascular and open surgery. The purpose of this prospective study was to evaluate the results of bypasses to the superior mesenteric artery arising from the infrarenal aorta or infrarenal aortic grafts. Methods. From January 1999 to December 2016, 24 consecutive patients with a mean age of 61 years underwent a prosthetic bypass to the superior mesenteric artery. Nine patients (37%) presented with an associated clinically important stenosis of the celiac artery and 10 (42%) of the inferior mesenteric artery. Five patients (21%) received preoperative parenteral nutrition. Four patients (17%) underwent dual antiplatelet treatment. The donor site was the infrarenal aorta in 19 patients (79%) and an infrarenal, Dacron graft was used in 5 (21%). The origin of the bypass was from the distal infrarenal aorta or Dacron graft in 19 patients (79%) and from the proximal infrarenal aorta in 5 patients (21%). The graft material consisted of 7 mm polytetrafluoroethylene in 19 cases (79%) and 7 mm Dacron in 5 cases (21%). A concomitant bypass to the inferior mesenteric artery was performed in 4 patients (17%). The primary end points were postoperative mortality, morbidity, graft infection, late survival, primary patency, and symptom‐free rate. The secondary end point was postoperative hemorrhagic complications. Results. No postoperative mortality occurred. Postoperative morbidity included a prolonged postoperative ileus in 4 patients (17%), transitory postoperative increases in serum creatinine concentrations in 3 patients (12%), and myocardial ischemia in 2 patients (8%). No postoperative hemorrhagic complications or graft infection were observed. Overall, the cumulative survival rate was 77% at 60 months. The overall late‐patency rate and freedom from recurrence of symptoms were both 87% at 60 months. Conclusion. Infrarenal aorta and infrarenal aortic grafts are an excellent source for the revascularization of the superior mesenteric artery. Bypasses to the superior mesenteric artery from the infrarenal aorta, either isolated or associated with adjunctive bypass to the inferior mesenteric artery, yield results that are comparable with those obtained with complete digestive artery revascularization using other donor sources.

Schwannoma of the descending loop of the hypoglossal nerve: Case report

Highlights • Schwannomas of the descending loop of the hypoglossal nerve are extremely rare.• They may masquerade a carotid body tumor at preoperative imaging.• En bloc resection together with the descending branch ensures durable cure.

True aneurysm of the proximal occipital artery: Case report

Highlights • Aneurysms of the proximal occipital artery may cause symptoms by compressing adjacent structures.• Resection may require intubation by the nose.• Resection if usually followed by regeression of symptoms.

Hybrid treatment of tandem, common carotid/innominate artery and ipsilateral carotid bifurcation stenoses by simultaneous, retrograde proximal stenting and eversion carotid endarterectomy: Preliminary results of a case series

BACKGROUND Tandem stenoses of the internal carotid artery (ICA) and proximal, ipsilateral common carotid artery (CCA) or innominate artery can be treated with a hybrid approach, combining conventional carotid endarterectomy (CEA) and retrograde stenting of the proximal stenosis, through surgical exposure of the carotid bifurcation. The purpose of this study was to evaluate the results of combining eversion CEA with retrograde CCA/innominate artery stenting. MATERIAL AND METHODS From January 2015 to July 2017, 7 patients, 6 men of a mean age of 72 years (range 59-83 years) underwent simultaneous, retrograde stenting of the proximal CCA/innominate artery and an eversion CEA of the ipsilateral ICA, through surgical exposure of the carotid bifurcation, for severe tandem stenoses. The proximal stenosis involved the left proximal CCA in 4 patients, the proximal innominate artery in 2 patients and the right CCA in one patient. The procedure was performed under general anesthesia in a conventional operating room equipped with a mobile C-arm. A covered, balloon expandable stent was deployed over the proximal stenosis via a 6-F sheath directly introduced into the proximal CCA through the obliquely transected carotid bulb. After removing the sheath, debris were flushed through the carotid bulb and eversion CEA completed the procedure. Study endpoints were: postoperative stroke/mortality rate, cardiac mortality and morbidity, peripheral nerve injury, cervical hematoma, overall late survival, freedom from ipsilateral stroke and patency of arterial reconstruction. RESULTS No postoperative mortality or neurologic morbidity was observed in any patient. Cervical hematomas and peripheral nerve injuries were likewise absent. At a mean follow-up of 18 months, all the patients were alive, free from neurologic events of new onset and free from restenosis. CONCLUSION Combined proximal stenting and eversion CEA for tandem lesions seems a valid treatment, with the advantages of eversion CEA over other techniques of carotid bifurcation revascularization.

Results of subclavian to carotid artery bypass for occlusive disease of the common carotid artery: A retrospective cohort study

BACKGROUND Optimal treatment of significant atherosclerosis of the common carotid artery (CCA) is not well-defined. The purpose of this study was to evaluate the long-term results of prosthetic subclavian to carotid bypass for occlusive disease of the CCA. MATERIAL AND METHODS From January 1994 to December 2015, 45 patients, mean age 67 years, underwent an ipsilateral subclavian to carotid bypass for occlusive disease of the CCA. Thirty-eight patients (84%) presented with neurologic symptoms, including transitory ischemic attacks in 29 cases and minor strokes in 9 cases. The graft material consisted of a 7 mm polytetrafluoroethylene conduit, and the distal anastomosis was done on the carotid bulb in 21 patients, on the internal carotid artery in 19 cases, and on the distal CCA in 5 cases. Median length of follow-up was 58 months. Study endpoints were the combined postoperative stroke/mortality rate, graft infection, overall late survival, freedom from ipsilateral stroke, and graft patency. RESULTS Postoperative stroke/mortality rate was 2%. No graft infection was observed throughout follow-up. At 60 months, overall survival, freedom from stroke, and graft patency were 71% (standard error [SE] = 0.07), 98% (SE = 0.02), and 95.5% (SE = 0.06), respectively. CONCLUSIONS Subclavian to carotid bypass allows very good patency rates and excellent protection from postoperative and late stroke, remaining a benchmark for any other treatment method.

Simultaneous resection of an adenocarcinoma of the cardia and a synchronous adenocarcinoma of the sigmoid: Report of a case

Introduction Adenocarcinoma of the cardia synchronous with other intraabdominal neoplasms is very rare. We report the case of a Siewert type II adenocarcinoma of the cardia synchronous with an adenocarcinoma of the sigmoid both treated simultaneously by transjatal oesophago-gastrectomy and anterior resection of the sigmoid. Case report A 62 year-old male was admitted for a progressing dysphagia and weight loss. Oesophago-gastric fibroscopy detected an adenocarcinoma of the cardia extending to the distal 2 cm of the esophagus (Siewert typeII). A CT-scan of the chest and abdomen confirmed the cancer of the cardia and also decealed a synchronous tumor of the sigmoid. Both neoplasms were resected through a xipho-pubic laparotomy, with an ileostomy completing the procedure. Postoperative course was uneventful and ileostomy was closed four weeks later. The patient was subsequently addressed to oncological for adjuvant treatment. Discussion This report supports the indication of aggressive, simultaneous treatment of an adenocarcinoma of the cardia associated with a synchronous abdominal neoplasm, provided that both are resectable through the same surgical access, as anticipated at a preoperative, through diagnostic work-up. Conclusion Simultaneous resection of synchronous adenocarcinoma of the cardia and the sigmoid is feasible and avoids possible progression of the untreated neoplasm during the interval between two separate resections, provided that a curative resection can be obtained for both diseases.
