Purpose: This study describes technical success, feasibility, and early results of fenestrated and branched endovascular aortic repair (F/B-EVAR) for treatment of thoracoabdominal aortic aneurysms (TAAAs) or pararenal aneurysms with more than 4 target visceral vessels (TVs) due to renovisceral arterial anatomical variations. Materials and Methods: Patients with TAAAs or pararenal aortic aneurysms who had more than 4 TVs due to renovisceral arterial anatomical variations of renal, celiac, and/or superior mesenteric arteries and received F/B-EVAR between January 2017 and September 2019 at a single aortic center were included in this study. We analyzed technical success, feasibility, and early outcomes. Results: Twelve patients (mean age 70±10 years, 9 males) were included. The anatomical variations included 6 right accessory renal arteries, 8 left accessory renal arteries, and 1 celiac artery variant. Stent-grafts were fenestrated, branched or combined in 6, 5, or 1 patients, respectively. The mean operating time was 346±120 minutes, the mean fluoroscopy time was 80±29 minutes, and the mean radiation dose area product was 430±219 Gy·cm2. The mean contrast volume was 129±45 mL. The total number of TVs was 64; 5 TVs in 9 patients, 6 in 2 patients, and 7 in 1 patient. Technical success was achieved in all cases. The mean intensive care unit stay was 6±5 days, and the mean total hospital stay was 14±10 days. One patient died early (30-day). Early morbidities included respiratory complication in 1 patient, renal insufficiency in 1 patient, and wound infection in 2 patients. No spinal cord ischemia, stroke, or bowel ischemia occurred. Early computed tomography angiography showed 100% patency of the bridging covered stents and TVs. The mean follow-up was 13±4.3 months. No mortality or adverse major event occurred during the follow-up. Two patients with developed type Ic endoleak related to 1 right renal artery and 1 celiac artery covered stent. Patency of the TVs during follow-up was 100%. Conclusion: The use of F/B-EVAR for the treatment of TAAA with more than 4 TVs due to renovisceral arterial anatomical variations in our own experience is feasible and not related to increased morbidity and mortality.

Anatomical Arrangement

AbstractThe aim of the study was to describe the possible anatomical variations in origin of the branches arising from the descending aorta in rabbit and hare. The study was carried out on ten adult rabbits and ten adult European hares. The study was carried out using the corrosion technique. After the euthanasia, the vascular network was perfused with saline. Spofacryl Dental © was used as a casting medium. After polymerisation of the medium, the maceration was carried out in KOH solution. We found high variability in origin of the branches arising from the descending aorta in both species. The variations in the level of the origin of the celiac artery, cranial mesenteric artery, renal arteries, ovarian arteries, testicular arteries and caudal mesenteric artery were present between both species and within the same species. In some individuals of both species, variations in the level and the arrangement of the origin of the dorsal intercostal arteries, lumbar arteries and median sacral artery were present. According to our results, it can be concluded that the anatomical arrangement of branches of descending aorta shows a higher number of variations in domesticated rabbit in comparison with the hare.

Symptomatic Stenosis

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

Pancreaticoduodenal Arcade

This case report describes the chemoembolization of a small hepatocellular carcinoma employing a lipiodol drug delivery system utilizing a novel arterial pathway. Because the target lesion was precariously located adjacent to the inferior heart border and the diaphragm, it was unsuitable for imaging-guided microwave ablation. To achieve chemoembolization, several intraprocedural adaptations were necessary, given the variant anatomy encountered and difficulty accessing the left gastric artery through a celiac artery approach. The left gastric artery was selected from a superior mesenteric artery approach through the pancreaticoduodenal arcade (Rio Branco’s arcade). This case illustrates the importance of a mastery of the vascular anatomy and variants of hepatic arterial flow.

Increased Risk

Preoperative evaluation of maxillary sinus anatomy is very important to avoid surgical complications due to close anatomical relations between the sinus and the posterior maxillary teeth and/or edentulous alveolar ridge. Posterior superior alveolar artery is a branch of the maxillary artery and provides the vascularization of the lateral sinus wall and underlying mucosa. Maxillary artery branches should be taken into consideration during sinus lifting procedures and bone augmentation due to increased risk of bleeding by damaging the artery during the osteotomy. Computed tomography (CT) explores three-dimensional anatomic structures and provides complex and accurate information about them. Cone Beam Computed Tomography (CBCT) offers an accurate view of the teeth and surrounding structures at high resolution, despite low-dose radiation used. In this study, the incidence of anatomical variations and sinus pathology were assessed using CBCT. The aim is to evaluate the presence of sinus pathology (sinus mucosal thickening, oro-antral communications, sinus tumors, cysts, polyps), presence and position of the posterior superior alveolar artery. These issues are important because they are about the limits of the dental implants in the posterior maxillary area. The presence of sinus pathology and anatomical variations may predispose to complications and even failures of implantation therapy.
