The anterior interosseous artery (AIA) plays an essential role in designing the posterior interosseous forearm flap (P.I.F.F). Understanding about anatomy of this artery permit us to find us to find out new solutions to design the P.I.F.F. in situations at which there are variations of the PIA. Objectives: (I) to evaluate the role of the anterior interosseous artery in the blood supplying to the posterior forearm region; (II) assessing the importance of anterior interosseous artery in designing the posterior interosseous forearm flap. Methods: 27 forearms of adults obove 25 years old, including 25 forearms fixed in formalin 4% and 2 fresh forearms, are objects for us to expose the AIA and PIA by different techniques. Results: There are 2-5 perforating branches of the AIA to the deep muscular layer of posterior. They connect to each other and to the muscular branch of the PIA, and their diameter becomes much larger in two cases of absence of the PIA. Branches from this series of arterial anastomoses distribute also to the skin of inferior half of posterior forearm. The posterior terminal branche of the AIA divides into the medial and recurrent branch. These two branches ascend and anastomose with the PIA and the muscular branch of the PIA, respectively. The medial branch of the posterior terminal branch is absent or disconnected with the PIA at two other cases. Conclusion: Our results indicate that the AiA supplies the inferior half and the deep muscular layer of the posterior forearm. The posterior interosseous forearm flap can still be raised in situations at which the posterior terminal branch of AIA communicates with the dorsal carpal arcus but not with the PIA and the PIA is absent.

66 flaps including 6 controlled, were divided into two models, each includes 30 flaps and each model was divided into 5 groups, evaluated after 4, 8, 12, 16 and 20 days after implantation. From the random implantation of a isolated pedicle of artery or vena in an abdomen skin flap, new blood vessels occurred and connected with the existent system of vessels in the flap. After 20 days, new vascularity was established in both models, as the same in the control group. Blood supply was considered appropriate and the flap could be moved safely along the newly implanted pedicle

OBJECTIVES: To clarify the anatomical distribution of the lingual artery in normal adult subjects through histopathologic evaluations. METHODS: Eighteen healthy cadaveric tongues were used to produce 8 paraffin-embedded tissue sections each. Length from midline raphe, depth from dorsum of tongue and the whole transverse length tongue were measured. The lateral distance, depth, and proportion of lateral distance of deep lingual artery were determined from tip to base of tongue gradually. Lateral distance is length from median raphe to the center of deep lingual artery lumen. Depth is vertical distance from dorsal surface of tongue to the center of deep lingual artery. Proportion of lateral distance is obtained by dividing lateral distance with transverse length from median raphe to lateral border of tongue. The degree of symmetry between right and left sides and the difference between selected spots were evaluated. RESULTS: Right and left sides of the lingual artery were symmetric. The lingual artery was lateralized as it run posterior. The lingual artery runs gradually deeper from the surface as it goes near the base of tongue. Both length and depth of the lingual artery gradually increased between 0%–75% of the mobile tongue, but 75%–100% zone of the lingual artery showed no significant difference. There was no anastomosis between right and left side of the lingual arteries. The lingual artery was located within 50% of the transverse length of tongue from median raphe. CONCLUSION: The present study reveals 3-dimensional information on the anatomical distributions of the lingual artery in normal adult subjects. These findings gives us beneficial information about the handling of the lingual artery during oral and base of tongue-related surgery.

A reconstruction following a resection of malignant oral cavity tumors is one of the most difficult problems in recent oral oncology. For a better understanding of oral and maxillofacial reconstructive procedures, basic and advanced microvascular anastomosis techniques must be learned and memorized. The aim of this article was to clarify and define the microvascular anastomosis methods, such as primary closure after an arteriotomy, end to side anastomosis, end to end anastomosis, and side to side anastomosis with an artery and vein. This review article discusses the basic skills regarding microvascular anastomoses with brief schematic diagrams in the Korean language. This article is expected to be helpful, particularly to young doctors in the course of the Korean national board curriculum periods for oral and maxillofacial surgery.

OBJECTIVETo investigate the value and safety of the surgery with vascular resection and reconstruction during pancreatectomy for pancreatic cancer.

METHODSThe clinical data of 206 patients with pancreatic cancer who underwent radical resection were retrospectively analyzed from January 2009 to March 2014 in Lihuili Hospital, Medical center of Ningbo.All cases were divided into non-vascular resection group(132 cases), the combined vein resection group(66 cases) and the combined arterial resection group(8 cases). The peri-operation data, the incidence of postoperative complications and the survival were compared in pairs among three groups.All patients were followed up till September 2014.

RESULTSThere were no statistical differences for the preoperative data among three groups.The operation time and the blood loss (M(QR)) were (347±96)minutes and (500(400)) ml in non-vascular resection group, (425±91)minutes and (800(500))ml in combined vein resection group, (508±120)minutes and (1 750(2 075))ml in combined arterial resection group, with significant differences among three groups(all P<0.01). The incidence of postoperative complication was 16.7%(22/132) in non-vascular resection group, 28.8%(19/66) in combined vein resection group, and 6 cases in combined arterial resection group, respectively.There were significant differences between non-vascular resection group and combined vein resection group(P<0.05), non-vascular resection group and combined arterial resection group(P<0.05), as well as between combined vein resection group and combined arterial resection group(P<0.05). The median survival time was 15 months for non-vascular resection group, 15 months for combined vein resection group, and 12 months for combined arterial resection group.No significant difference was found among three groups(all P>0.05). The postoperative mortality was nil for all of groups.

CONCLUSIONSCompared with non-vascular resection, combined vein resection can be performed safely with a similar prognosis. The surgery of combined arterial resection could only be justified when R0 resection for pancreatic cancer could be achieved for highly selected patients.

Renal angiomyolipoma is a type of benign tumor that occurs sporadically in addition to being associated with tuberous sclerosis. Preoperative embolization of large tumors is important to avoid excessive blood loss during surgery. We reported a patient with a 5505-g giant renal angiomyolipoma in a solitary kidney. The patient was treated with preoperative embolization and radical nephrectomy without complications. This type of treatment for an enormous angiomyolipoma can reduce the risk of uncontrolled hemorrhage caused by rupture of the tumor during the operation and should be considered for the treatment of similar tumors.

OBJECTIVE: To analyze clinical features, surgical treatment and outcomes of neurilemmoma and carotid body tumors in bifurcation of carotid artery. METHODS: The clinical data of 17 patients with neurilemmomas and 76 patients with carotid body tumors at the bifurcation of carotid artery, who were surgically treated in Zhongshan Hospital of Fudan University from March 2012 to November 2016, were retrospectively analyzed. The clinicopathological characteristics, surgical procedures and outcomes were compared between two groups. RESULTS: No difference of preoperative clinical demographic data was found between two groups. Operation time of the neurilemmoma group was significantly shorter than that of the carotid body tumor group[(93.9±30.8) min vs. (159.3±52.9) min, <0.01]. The neurilemmoma group had lower volume of intra-operative blood loss[(110±96) mL vs. (356±239) mL, <0.01] and lower rate of external carotid artery resection (11.8% vs. 68.4%, <0.01) than the carotid body tumor group. In the neurilemmoma group, 17 tumors were completely resected and no malignant disease was found. In the carotid body tumor group, 76 patients underwent complete surgical resection for the tumor, of which 5 (6.6%) were malignant. Tumor size of the neurilemmoma group was larger than that of the carotid body tumor group[(4.5±1.4) cm vs. (3.1±1.0) cm, <0.01]. There was no significant difference in the incidence of peri-operative complications and length of hospital stay between two groups (>0.05). CONCLUSIONS The clinical manifestations of neurilemmoma and carotid body tumors at carotid artery bifurcation are similar. The carotid body tumor group has a longer operating time, larger intra-operative blood loss, higher external carotid resection rate and relative higher incidence of malignancy. More cautions should be given when carotid body tumors at carotid artery bifurcation are treated.
