Abstract
Abstract
The aim of this paper was to describe the branching schema of the ventral branches of the abdominal aorta: the a. celiaca, the a. mesenterica cranialis and the a. mesenterica caudalis. The study was carried out on nine adult European hares using the corrosion cast technique. After the euthanasia, the vascular network was perfused with saline. Batson’s corrosion casting kit No. 17 was used as a casting medium. After polymerisation of the medium, the maceration was carried out in KOH solution. In all specimens, the first branch originating from the a. celiaca was the a. lienalis. The a. hepatica was present as the second branch in four cases and as the third branch also in four cases. The first branch of the a. mesenterica cranialis was the a. colica media in seven cases. The second branch was represented by the a. pancreaticoduodenalis caudalis also in seven cases. Two aa. jejunales originated as the third branch. In seven cases, the fourth branch formed the truncus jejunalis and the fifth branch the a. ileocecalis. The a. mesenterica caudalis had a uniform arrangement in all of the specimens. The results enabled us to conclude that there was higher variability of the branching pattern of the a. celiaca in comparison with the a. mesenterica cranialis and the a. mesenterica caudalis in the European hare.

Abstract
Abstract
The aim of this research was to describe the level of origin of the branches originating from the ventral surface of the abdominal aorta in the rabbit and hare. The study was carried out on ten adult rabbits and ten adult European hares using the corrosion cast technique. After euthanasia, the vascular network was perfused with saline. Batson’s corrosion casting kit No. 17 was used as a casting medium. After polymerization of the medium, the maceration was carried out in a KOH solution. We found variable levels of the origin of the celiac, cranial mesenteric and caudal mesenteric arteries in both species. In the rabbit, the celiac artery originated in the majority of cases at the cranial end of the first lumbar vertebra and in the hare at the middle part of the vertebral body of the same vertebra. The cranial mesenteric artery in the rabbit originated predominantly at the level of the first lumbar vertebra and in the hare at the level of the second lumbar vertebra. In the rabbit, the caudal mesenteric artery originated mainly at the level of the sixth lumbar vertebra and in the hare, at the level of the fifth lumbar vertebra. We concluded that there were higher variabilities of the origins of the ventral branches of the abdominal aorta in domesticated rabbit in comparison with the European hare.

Absorb Bioresorbable Vascular Scaffold in Complex Coronary Bifurcation Interventions: Insights From an In Vivo Multimodality Imaging Study. Circ Cardiovasc Interv 2016; 9:CIRCINTERVENTIONS.116.003849. [PMID: 27512090 DOI: 10.1161/circinterventions.116.003849] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2016] [Accepted: 07/15/2016] [Indexed: 01/21/2023]
Abstract
BACKGROUND Although bioresorbable scaffolds offer potential advantages compared with metallic drug-eluting stents in the treatment of complex coronary bifurcation lesions, there are concerns that the polymeric scaffold integrity may be compromised. This in vivo study sought to provide insights about the feasibility of performing complex bifurcation stenting with Absorb bioresorbable vascular scaffolds (Abbott Vascular, Santa Clara, CA). METHODS AND RESULTS Twenty New Zealand white rabbits underwent stenting of the nondiseased aortoiliac bifurcation with bioresorbable vascular scaffolds using provisional (PS, n=5), culotte (n=5), modified-T (n=5), or T-and protrusion (n=5) stenting techniques. Angiography, optical coherence tomography, and microcomputed tomography were performed. Angiographic results were excellent without evidence of dissection or side branch (SB) compromise. PS optimally opened the SB ostium without deforming the main vessel (MV) bioresorbable vascular scaffolds, avoiding malapposition, and revealing a single connector fracture in 1 of 5 cases on microcomputed tomography. Culotte stenting resulted in complete bifurcation coverage with extensive segments of double-layered struts and inappropriately apposed struts at the bifurcation level in 3 of 5 cases. On microcomputed tomography, there was MV and SB scaffold distortion at the bifurcation with single strut fractures in 4 of 5 and double fractures in 1 of 5. Modified-T and T-and protrusion resulted in complete bifurcation coverage and in minimal double-strut layers at the neocarina. On microcomputed tomography, no strut fractures were present after modified-T, whereas in 3 of 5 T-and protrusion procedures single strut fractures were noted. CONCLUSIONS Bifurcation stenting using bioresorbable vascular scaffolds is feasible with excellent angiographic results. PS with additional T-and protrusion whenever needed seems a reasonable approach. Whenever a 2-stent technique is planned, modified T-stenting appears the most promising.
