【Objective】 To explore the effect of recovery autologous blood transfusion combined with bilateral internal iliac artery presetting in high-risk patients with hemorrhage during cesarean section. 【Methods】 A total of 162 high-risk patients with hemorrhage who underwent cesarean section from January 2021 to May 2023 in our hospital were prospectively selected and divided into in Groups A, B, and C with 54 cases in each group according to the indications for the method of transfusion. Group A received allogeneic blood transfusion, Group B received autologous blood transfusion, Group C received autologous blood transfusion combined with bilateral internal iliac artery balloon presetting. 【Results】 Intraoperative blood loss (mL) (1 600 vs 1 500 vs 800), postoperative hospital stay(d) (7 vs 7 vs 6) and operative time(min) (107 vs 104.50 vs 77) in group C were all lower than those in group A and B (P0.05); The autologous blood transfusion volume(mL) in group C was lower than that in group B (525.5 vs 261, P0.016 7). 【Conclusion】 Recovery autologous blood transfusion combined with bilateral internal iliac artery balloon presetting in cesarean section for high-risk patients with hemorrhage achieved ideal effects, which can significantly reduce intraoperative blood loss, intraoperative autologous blood transfusion, allogeneic red blood cells and plasma transfusion, as well as the operation time and postoperative hospital stay. In addition, it can improve the coagulation function and hysterectomy, which is conducive to ensuring the safety of maternal and promoting early rehabilitation, and preserving the fertility of patients to a certain extent, which is worthy of further clinical promotion.

Effect of internal iliac artery calcification on delayed graft function and short-term prognosis of kidney transplant recipients / 器官移植

Objective To analyze the correlation between internal iliac artery calcification and delayed graft function (DGF) and short-term prognosis of kidney transplant recipients. Methods Clinical data of 222 kidney transplant recipients were retrospectively analyzed. According to the recovery of renal function, all recipients were divided into the DGF group (n=50) and immediate graft function (IGF) group (n=172). According to whether the recipients were complicated with severe internal iliac artery calcification, DGF and IGF groups were further divided into the high-risk DGF (n=22), low-risk DGF (n=28), high-risk IGF (n=41) and low-risk IGF(n=131) subgroups, respectively. Clinical data of donors and recipients were statistically compared between two groups. The incidences of postoperative DGF and internal iliac artery calcification were recorded. The risk factors of DGF after kidney transplantation, and the correlation between internal iliac artery calcification and clinical parameters were analyzed. Short-term prognosis of recipients with DGF complicated with severe internal iliac artery calcification was evaluated. Results The incidence of DGF was 22.5% (50/222). Among all recipients, 28.4% (63/222) were complicated with severe internal iliac artery calcification. In the DGF group, 44% (22/50) of the recipients were complicated with severe internal iliac artery calcification, higher than 23.8% (41/172) in the IGF group (P < 0.05). Univariate analysis showed that high serum creatinine (Scr) level of donors, male donor, high triglyceride level and severe internal iliac artery calcification of recipients were the risk factors for DGF after kidney transplantation (all P < 0.05). Multivariate logistic regression analysis revealed that Scr≥143 μmol/L of donors and severe internal iliac artery calcification of recipients were the independent risk factors for DGF after kidney transplantation (both P < 0.05). Correlation analysis indicated that internal iliac artery calcification was weakly correlated with the age of recipients and renal artery anastomosis (both P < 0.05). In the DGF group, the Scr level at postoperative 1 month was significantly higher, whereas the estimated glomerular filtration rate (eGFR) was significantly lower than those in the IGF group (both P < 0.05). The eGFR at postoperative 12 months in the high-risk DGF subgroup was significantly lower than those in the low-risk DGF, high-risk IGF and low-risk IGF subgroups (all P < 0.05). Conclusions Internal iliac artery calcification is not only a risk factor for recovery of renal allograft function, but also negatively affects short-term prognosis of renal allograft function.

Advances in surgical treatment of internal iliac artery aneurysms / 国际外科学杂志

The internal iliac artery originating from the common iliac artery is an important branch, and communicating with the branches of the abdominal aorta, such as lumbar artery and sacral median artery, forming rich collateral circulation and nourishing the blood supply of gluteal muscle and pelvic floor viscera. Surgical intervention is recommended when the maximum diameter of internal iliac artery aneurysms>2 cm. A variety of treatment modalities are available, particularly, endovascular technique has been successfully applied in the clinical treatment of internal iliac artery aneurysms, which can significantly improve the cure and reduce complications and deaths. This article reviews the previous literature and summarizes the progress of internal iliac artery aneurysms treatment.

Bilateral internal iliac artery ligation: the procedure of choice in life threatening postpartum haemorrhage

Background: The present study was to assess the indication and study the intraoperative and postoperative complications of bilateral internal iliac artery ligation. Aim of this study was to evaluate the effectiveness of internal iliac artery ligation in arresting postpartum haemorrhage.Methods: This is a retrospective study carried out between January 2015 to December 2018 at Shrimati Kashibai Navale Medical College and General Hospital, Pune. This study included 48 patients with life-threatening PPH. Bilateral internal iliac artery ligation was done by anterior approach in 7 patients and by posterior approach in 41 patients.Results: Intraoperative and postoperative complications were noted in all patients. Of the total patients, 10 required massive blood transfusion and 12 underwent obstetrical hysterectomies (n=12; 25%). Internal iliac vein injury was seen in 1 patient (n=1; 2.08%) and external vein thrombosis was noted in 3 patients (n=3; 6.25%). Maternal mortality was observed in 1 patient due to DIC on day 9 (n=1; 2.08%). The uterine salvage rate was 75%.Conclusions: Internal iliac artery ligation (IIAL) safe, rapid, effective, time tested method of controlling bleeding from genital tract.

Efficacy of internal iliac artery ligation for control of post-partum haemorrhage

Background: Pelvic hemorrhage is associated with a great degree of morbidity and mortality and has to be controlled immediately. Ligation of the internal iliac arteries is a method to achieve the goal. We conducted this study to assess the outcome, effectiveness and complications of internal iliac artery ligation (IIAL) in controlling postpartum haemorrhage.Methods: This study was a retrospective study conducted in a rural tertiary referral centre from April 2015 to March 2018. IIAL was performed in women with PPH either at caesarean section or at laparotomy performed at a variable time after vaginal or caesarean delivery.Results: Over the study period of 3 years, 29 cases of IIAL were performed. The most common indication for IIAL was atonic PPH. Uterine salvagability was 62% in this study.Conclusions: All obstetric surgeons should be fully aware of the indications, timing and technical aspects of IIAL. Bilateral internal iliac artery ligation remains a safe, fast, effective and life saving salvage procedure which should be encouraged and used routinely by obstetricians when faced with cases of severe obstetric hemorrhage, especially in young women of low parity.

Obstetric hysterectomy: a receding trend

Over 500,000 women die each year due to complications of pregnancy and childbirth, a number that has remained relatively unchanged since 1990, when the first global estimates of the burden of maternal mortality were developed. Hemorrhage due to uterine atony, adherent placenta and PPH are still the causes of maternal death in developing countries. Although advances have been made in the development of conservative medical and surgical treatment of obstetric haemorrhage like brace sutures, internal iliac artery ligation, selective arterial embolization etc emergency obstetric hysterectomy remains a lifesaving procedure in the management of intractable haemorrhage unresponsive to conservative management.

Comparison of temporary occlusion of abdominal aorta, temporary occlusion of common iliac artery and internal iliac artery ligation in the treatment of complex acetabular fracture / 中华创伤骨科杂志

Objective To compare the effectiveness of controlling blood loss in the treatment of complex acetabular fracture between temporary occlusion of abdominal aorta by interventional balloon (TOAAIB),temporary occlusion of common iliac artery by interventional balloon (TOCAIIB) and internal iliac artery ligation (IIAL).Methods Included for this study were 113 complex acetabular fractures which had been treated at Department of Orthopaedic Trauma,Shaoguang Hospital Affiliated to Southern Medical University from January 2000 through January 2017.There were 68 males and 45 females,aged from 23 to 61 years (average,42.3 years).According to the Letournel classification,all of them belonged to complex fractures,including 10 T-type,24 double-column,16 posterior column & posterior wall,46 transverse & posterior wall and 15 anterior & posterior half-transverse ones.They were all treated by open reduction and internal fixation but differed in surgical hemostasis techniques:TOAAIB was used in 37cases,TOCAIIB in 31 and IIAL in 45.Fracture reduction was evaluated by Matta criteria.Intraoperative bleeding and postoperative wound drainage,fracture union and complications related to interventions were recorded.Hip function was evaluated by Modified d'Aubigne & Postal clinical grading system after fracture healing.Results The 3 groups (TOAAIB,TOCAIIB and IIAL) were comparable because there were no significant differences in gender,age,time from injury to surgery,Letournel classification or surgical approaches between the patients in the 3 groups (P ＞ 0.05).Anatomical reduction was achieved in 91.15％ of the patients (103/113) and satisfactory reduction in 8.85％ (10/113).Intraoperative hemorrhage was 1,631.5 ±675.5 mL in the HAL group,892.6 ±217.7 mL in the TOCAIIB group and 648.0 ± 170.2 mL in the TOAAIB group,showing significant differences between the 3 groups (P ＜ 0.05).One case of femoral artery thrombosis occurred in the TOAAIB group at the end of operation but was cured by symptomatic treatment of anticoagulation.There were no interventional complications in the other 2 groups.There were no significant differences between the 3 groups in postoperative wound drainage,fracture union time,hip function score or complications (P ＞ 0.05).Conclusions In controlling intraoperative bleeding in the surgery for complex acetabular fracture,TOAAIB may be the best,followed by TOCAIIB,and IIAL may be the worst.However,choice of a proper surgical hemostasis technique should also depend on the specific intraoperative condition of a specific patient.

Fogarty balloon and conventional balloon for occlusion of internal iliac artery during caesarean section for pernicious placenta previa / 中国介入影像与治疗学

Objective To: compare the application value of Fogarty balloon and conventional balloon for occlusion of internal iliac artery during caesarean section for pernicious placenta previa (PPP). Methods: Data of 57 pregnant women with PPP were retrospectively analyzed. The patients were divided into group A (n=27, using Fogarty balloon) and group B (n=30, using percutaneous transluminal angioplastry [PTA] conventional balloon)for internal iliac artery occlusion. The balloons were placed into bilateral internal iliac arteries before cesarean section. After the delivery of fetus, the balloons were dilated. Whether the balloons were deflated immediately depended on the amount of intraoperative bleeding after complete separation of placenta. The patients were treated with DSA-guided uterine artery embolization, hysterectomy or transferred into intensive care unit (ICU) after cesarean section if necessary. The clinical outcomes were analyzed and classified into good (discharge smoothly after cesarean section) and poor (occurring postoperative complications, needing uterine artery embolization, hysterectomy or getting ICU admission). The differences of duration time of cesarean section, intraoperative bleeding volume, blood transfusion, uterine artery embolization, duration of hospitalization and clinical outcomes were statistically compared between the two groups. Results: The duration time of cesarean section of group A was significantly shorter than that of group B ([72.37±17.39]min vs [86.93±27.79]min, t=-2.40, P=0.02). The proportion of transfusion of group A was lower than that of group B (44.44% [12/27]) vs 73.33% [22/30], χ2=4.93, P=0.03). The intraoperative bleeding volume (500[300]ml vs 700[150]ml, U=190, P<0.01) and the blood transfusion volume (0 [400]ml vs 400 [800]ml, U=249, P=0.01) of group A were significantly lower than those of group B. There was no significant difference of uterine arterial embolization (χ2=1.52, P=0.22), duration of hospitalization (t=-0.12, P=0.91)nor clinical outcomes (χ2=1.38, P=0.24) between the two groups. Conclusion: Compared with PTA conventional balloon, Fogarty balloon is more effective in blocking internal iliac artery blood flow during cesarean section, which can further reduce the volume of intraoperative bleeding and shorten the duration of cesarean section.

Analysis of early treatment of multiple injuries combined with severe pelvic fracture / 中华创伤杂志(英文版)

PURPOSE@#To summarize and analyze the early treatment of multiple injuries combined with severe pelvic fractures, especially focus on the hemostasis methods for severe pelvic fractures, so as to improve the successful rate of rescue for the fatal hemorrhagic shock caused by pelvic fractures.@*METHODS@#A retrospective analysis was conducted in 68 cases of multiple trauma combined with severe pelvic fractures in recent 10 years (from Jan. 2006 to Dec. 2015). There were 57 males and 11 females. Their age ranged from 19 to 75 years, averaging 42 years. Causes of injury included traffic accidents in 34 cases (2 cases of truck rolling), high falling injuries in 17 cases, crashing injuries in 15 cases, steel cable wound in 1 case, and seat belt traction injury in 1 case. There were 31 cases of head injury, 11 cases of chest injury, 56 cases of abdominal and pelvic injuries, and 37 cases of spinal and limb injuries. Therapeutic methods included early anti-shock measures, surgical hemostasis based on internal iliac artery devasculization for pelvic hemorrhage, and early treatment for combined organ damage and complications included embolization and repair of the liver, spleen and kidney, splenectomy, nephrectomy, intestinal resection, colostomy, bladder ostomy, and urethral repair, etc. Patients in this series received blood transfusion volume of 1200-10,000 mL, with an average volume of 2850 mL. Postoperative follow-up ranged from 6 months to 1.5 years.@*RESULTS@#The average score of ISS in this series was 38.6 points. 49 cases were successfully treated and the total survival rate was 72.1%. Totally 19 patients died (average ISS score 42.4), including 6 cases of hemorrhagic shock, 8 cases of brain injury, 1 case of cardiac injury, 2 cases of pulmonary infection, 1 case of pulmonary embolism, and 1 case of multiple organ failure. Postoperative complications included 1 case of urethral stricture (after secondary repair), 1 case of sexual dysfunction (combined with urethral rupture), 1 case of lower limb amputation (femoral artery thrombosis), and 18 cases of consumptive coagulopathy.@*CONCLUSION@#The early treatment of multiple injuries combined with severe pelvic fractures should focus on pelvic hemostasis. Massive bleeding-induced hemorrhagic shock is one of the main causes of poor prognosis. The technique of internal iliac artery devasculization including ligation and embolization can be used as an effective measure to stop or reduce bleeding. Consumptive coagulopathy is difficult to deal with, which should be detected and treated as soon as possible after surgical measures have been performed. The effect of using recombinant factor VII in treating consumptive coagulopathy is satisfactory.

A Cadaveric Study Of Variability In The Origin Of Obturator Artery

Background: The origin of obturator artery (OA) is important clinically because of its vascular role. The OA is oneof the branches of the anterior division of the internal iliac artery. The source of OA has been documented from allpossible neighboring arteries. So the course and ramification of the OA have received attention for gynecologistsand surgeons.Materials and Methods: Study was conducted on 30 bisected pelvises specimens in Department of Anatomy,Gulbarga Institute of medical sciences, Gulbarga The pattern of origin of the obturator artery was identified. Theobturator artery was traced from its origin to it extends till the obturator foramen.Results: In 80% (24 sides) the origin of obturator artery was from the internal iliac artery. In 76.7% (23 specimens),the obturator artery was originated from anterior division of internal iliac artery. Out of these, 46.7% (14 specimens),the obturator artery arouses as a single and direct branch of the anterior division of the internal iliac artery whilevariation in its origin as a common trunk was observed in 30% (9 specimens). In 20% (6 sides), it arouses from theexternal iliac artery i.e. from an inferior epigastric artery.Conclusion: Anomalous origin of OA may injure during surgical repair of hernia and fracture of superior ramus ofpubis. The sound knowledge on anatomical variations of OA is very important to the general and vascularsurgeons for successful outcome of the above mentioned surgical procedures and will help them to avoidunnecessary complication.

Preservation technique of internal iliac artery in performing endovascular aortic repair / 介入放射学杂志

Endovascular aortic repair (EVAR) has been the main treatment means for abdominal aortic aneurysm.It has become an expert consensus that in the case of abdominal aortic aneurysm that is complicated by iliac aneurysm,the preservation of internal iliac artery is necessary because it can prevent the occurrence of gluteal muscle ischemnia,sigmoid ischemia,male sexual dysfunction and other complications.In recent years,with the continuous updating of the endovascular devices it has become possible to retain the internal iliac artery in the performance of EVAR.At present,the reconstruction of internal iliac artery in EVAR includes a variety of techniques,including intraluminal iliac branched device (IBD) technique,sandwich technique,common iliac artery covered-stent bell-bottom (BBT) technique,external iliac artery-internal iliac artery intraluminal shunt technique (reverse chimney technique),and spring coil embolism technique.This article aims to make a summary of all the above mentioned techniques.

Endovascular repair of common iliac artery aneurysms with modified branched stent grafts / 中华普通外科杂志

Objective To present our initial experience with modified branched stent gratis in endovacular repair of common iliac artery aneurysms.Methods In 5 patients,3 were aortobiiliac aneurysms and 2 were single common iliac aneurysms,receiving endovascular repair by a novel modified branched stent graft to keep at least one internal iliac artery patency.Results All cases were successfully completed with patent external and internal iliac artery on the target side.There were no inhospital mortality nor major complications after graft stenting.During a follow-up period of 27.6 months (21 to 33 months),there have been no stenting related endoleak and branch occlusion.Conclusions Modified branched stent graft is safe and efficient,providing an effective way to protect internal iliac artery in endovascular treatment of common iliac aneurysms.

Variability in the Origin of the Obturator Artery: A Descriptive Cross-Sectional Cadaveric Study.

Background: Surgeons must be conscious of unexpected sources of hemorrhage, such as an aberrant obturator artery or vein, and unexpected iliopubic vessels and take appropriate precautions to avoid injury to these structures. Objective: Evaluating the incidence of normal and aberrant origin of the obturator artery and vein. Materials and Methods: A total of 72 human hemi-pelvises were taken including both the fresh cadavers arrived in mortuary with preserved pelvises in Department of Anatomy at Netaji Subhash Chandra Bose Medical College, Jabalpur. Laparotomy done with midline anterior incision up to the pubic symphysis and dissection carried out in the pelvic and retropubic region to expose the branches of the common iliac artery. Results: Obturator artery common originates from the anterior trunk of the internal iliac artery and less frequently from other branches of internal or external iliac artery. Abnormal communication found in 45.8% of hemi-pelvises which are mostly venous. Conclusion: Obturator artery the most common originates from anterior trunk of internal iliac artery. Abnormal venous communications (venous corona mortis) are a very common and knowledge of abnormal communications of obturator vessels is crucial for the different surgeries at pelvic region.

Prophylactic bilateral internal iliac artery balloon occlusion in the management of placenta accreta: A 36-month review

Background: The contemporary obstetrician is increasingly put to the test by rising numbers of pregnancies with morbidly adherent placenta. This study illustrates our experience with prophylactic bilateral internal iliac artery occlusion as part of its management. Methods: Between January 2011 to January 2014, 13 consecutive patients received the intervention prior to scheduled caesarean delivery for placenta accreta. All cases were diagnosed by ultrasonography, color Doppler imaging and supplemented with MRI where necessary. The Wanda balloonTM catheter (Boston Scientific, Natick, MA, U.S.A) were placed in the proximal segment of the internal iliac arteries preceding surgery. This was followed by a midline laparotomy and classical caesarean section, avoiding the placenta. Both internal iliac balloons were inflated just before the delivery of fetus and deflated once haemostasis was secured. Primary outcomes measured were perioperative blood loss, blood transfusion requirement and the need for ICU admission. Results: The mean and median intraoperative blood loss were 1076mls±707 and 800mls (300-2500) respectively while mean perioperative blood loss was 1261mls±946. Just over half of the patients in our series required blood and/or blood products transfusion. Two patients (15.4%) required ICU admission. Conclusion: Our study suggests that preoperative prophylactic balloon occlusion of bilateral internal iliac arteries reduces both blood loss and transfusion requirement in patients with placenta accreta, scheduled to undergo elective caesarean hysterectomy. It is an adjunct to be considered in the management of a modern day obstetric problem, although the authors are cautious about generalizing its benefit without larger, randomized trials.

Variability of Origin of Obturator Artery and its Clinical Significance.

Background: Obturator artery is a branch of anterior division of internal iliac artery. It normally runs anteroinferiorly on the lateral wall of pelvis to the upper part of the obturator foramen and leaves the pelvis by passing through the obturator canal. On its course, the artery is accompanied by the obturator nerve and vein. It supplies the muscles of the medial compartment of the thigh. A severe and potentially lethal complication in pelvic injuries is arterial bleeding commonly involving the branches of the internal iliac artery, namely the lateral sacral, iliolumbar, obturator, vesical and inferior gluteal arteries. A sound knowledge of retro-pubic pelvic vascular anatomy is pivotal for successful performance of endoscopic procedures such as total extraperitoneal inguinal hernioplasty or laparoscopic herniorraphy. The context and purpose of the study: This study is an attempt to analyse the origin, course, distribution of obturator artery in pelvis and their clinical implication. Result: out of 60 formalin fixed pelvic halves 36.6% of the specimens, (26.67% in males and 10% in females) the origin of obturator artery was found to be normal from anterior division of internal iliac artery. About 63.63% from various other sources. Conclusion: This knowledge of variation in the origin of obturator artery is important while doing pelvic and groin surgeries requiring appropriate ligation. Such aberrant origins may be a significant source for persistent bleeding in the setting of acute trauma. Knowledge regarding the variations of obturator artery is useful during surgeries of fracture and direct or indirect inguinal, femoral and obturator hernias.

Left External Iliac and Common Femoral Artery Occlusion Following Blunt Abdominal Trauma without Associated Bone Injury

Blunt abdominal trauma may cause peripheral vascular injuries. However, blunt abdominal trauma rarely results in injuries to the external iliac and common femoral arteries, which often stem from regional bone fractures. Here, we present the case of a patient who had experienced trauma in the lower abdominal and groin area three months before presenting to the hospital, but these injuries did not involve bone fractures and had been managed conservatively. The patient came to the hospital because of left lower leg claudication that gradually became severe. Computed tomography angiography confirmed total occlusion of the external iliac and common femoral arteries. The patient underwent femorofemoral bypass grafting and was discharged uneventfully.

Groin and buttock claudication associated with vascular origin due to chronic occlusion of internal iliac artery: A case report

Neurogenic and vascular claudication is sometimes difficult to distinguish from each other due to similarities in symptoms. Symptoms and physical examinations may not always match the severity in both diseases, and when atypical symptoms, such as groin pain, are present, diagnosis can be more challenging. Proper differential diagnosis of the two is important because of the invasiveness of treatment in both diseases. We report a rare case of a patient with severe groin and buttock pain due to chronic occlusion of the internal iliac artery, along with a review of the relevant literature.

Study of Posterior Division of Internal Iliac Artery.

Background: The internal iliac artery originates from the common iliac artery at the level of sacroiliac joint. The internal iliac artery descends posterior to the greater sciatic foramen thereby dividing into anterior and posterior divisions. The posterior division of the internal iliac artery is known to give rise to three main branches i.e. iliolumbar artery, lateral sacral artery. Accidental haemorrhage is common during erroneous interpretation of anomalous blood vessels. The knowledge of the normal and the abnormal anatomy of the branches of the internal iliac artery is essential for obstetric surgeons. Methods: 50 adult human pelvic halves were procured from embalmed cadavers of J.J.M. Medical College and S.S.I.M.S & R.C, Davangere, Karnataka, India for the study. Results: Out of 50 specimens, ilio-lumbar artery took origin from posterior division, directly in 22 specimens (44%), with obturator artery in 5 specimens (10%) and with superior gluteal artery in 2 specimens (4%). From anterior division, with obturator artery in 6 specimens (12%) and with inferior gluteal artery in 1 specimen (2%). From common trunk, as direct branch in 10 specimens (20%), with lateral sacral artery in 1 specimen (2%), with vertebral branch in 1 specimen (2%), with superior gluteal artery in 1 specimen (2%) and was found to be absent in 1 specimen (2%). Posterior division of internal iliac artery given origin directly to superior gluteal artery in 44 specimens (88%), with ilio-lumbar artery in 1 specimen (2%), with obturator artery in 2 specimens (4%). Lateral sacral artery from posterior division was observed in 38 specimens (76%) and unpaired origin was observed in 7 specimens (14%). Conclusion: Internal iliac artery supplies the pelvic viscera and musculature the knowledge of its branches helpful in pelvis surgeries.
