Hematochezia due to rectal invasion by an internal iliac artery aneurysm: A case report

BACKGROUND This case report presents the rare occurrence of hematochezia due to an internal iliac artery aneurysm leading to an arterioenteric fistula,expanding the differential diagnosis for gastrointestinal bleeding.It emphasizes the importance of considering vascular origins in cases of atypical hematochezia,particularly in the absence of common gastrointestinal causes,and highlights the role of imaging and multidisciplinary management in diagnosing and treating such unusual presentations.CASE SUMMARY A 75-year-old man with a history of hypertension presented with 12 d of hematochezia,experiencing bloody stools 7-8 times per day.Initial computed tomography(CT)scans revealed an aneurysmal rupture near the right internal iliac artery with suspected hematoma development.Hemoglobin levels progressively decreased to 7 g/dL.Emergency arterial angiography and iliac arterycovered stent placement were performed,followed by balloon angioplasty.Despite initial stabilization,minor rectal bleeding and abdominal pain persisted,leading to further diagnostic colonoscopy.This identified a neoplasm and potential perforation at the proximal rectum.An exploratory laparotomy confirmed the presence of a hematoma and an aneurysm invading the rectal wall,necessitating partial rectal resection,intestinal anastomosis,and ileostomy.Postoperative recovery was successful,with no further bleeding incidents and normal follow-up CT and colonoscopy results after six months.CONCLUSION In cases of unusual gastrointestinal bleeding,it is necessary to consider vascular causes for effective diagnosis and intervention.

Does kidney transplantation onto the external iliac artery affect the haemodynamic parameters of the cavernosal arteries？

Reduced cavernosal arterial inflow has been hypothesized to be the likely cause of erectile dysfunction after kidney transplants in recipients revascularized through end-to-end anastomosis to the internal lilac artery, suggesting that end-to-side anastomosis at the external iliac artery is preferable. The aim of this study was to prospectively evaluate the effect of the use of the external iliac artery on erectile function, hormone profiles and penile blood flow by evaluating changes in penile colour Doppler ultrasound parameters in a consecutive series of 22 recipients before and after end-to-side external lilac artery transplantation. The mean International Index of Erectile Function-Erectile Function （IIEF-EF） domain score decreased significantly 3 months after transplant （18.09±6.33 vs. 22.50±7.09, P=O.01）. The reduction in peak systolic velocity （PSV） was significant for the cavernous artery homolateral to the side of transplant （42.60±18.77 vs. 52.01±19.91, P=0.01）. The mean postoperative end diastolic velocity （EDV） did not differ significantly from the preoperative value （P=0.74）. No statistical differences were found in the serum levels of testosterone or prolactin. Kidney grafts anastomosed at the external lilac artery produced significant （P=0.01） reductions in arterial inflow at the homolateral cavernosal artery that remained above the normal threshold. Whether these haemodynamic changes can explain the worsening of postoperative erectile function remains to be proven.

Emergency internal iliac artery temporary occlusion after massive hemorrhage during surgery of cesarean scar pregnancy:A case report

BACKGROUND Cesarean scar pregnancy(CSP)is rare but may result in uterine rupture during pregnancy or massive hemorrhage during abortion procedures.Awareness of this condition is increasing,and most patients with CSP are now diagnosed early and can be managed safely.However,some atypical patients are misdiagnosed,and their surgical risks are underestimated,increasing the risk of fatal hemorrhage.CASE SUMMARY A 27-year-old Asian woman visited our institution because of abnormal pregnancy,and she was diagnosed with a hydatidiform mole through transvaginal ultrasound(TVS).Under hysteroscopy,a large amount of placental tissue was found in the scar of the lower uterine segment,and a sudden massive hemorrhage occurred during the removal process.The bilateral internal iliac arteries were temporarily blocked under laparoscopy,and scar resection and repair were rapidly performed.She was discharged in good condition 5 d after the operation.CONCLUSION Although TVS is widely used in the diagnosis of CSP,delays in the diagnosis of atypical CSP remain.Surgical treatment following internal iliac artery temporary occlusion may be an appropriate management method for unanticipated massive hemorrhage during CSP surgery.

Subsequent pregnancy outcomes and fertility rates in the case series that underwent bilateral hypogastric artery ligation(BHGAL)due to severe postpartum hemorrhage

Objective:To evaluate the effect of bilateral hypogastric artery ligation(BHGAL)on women's pregnancy outcomes and fertility rates in cases with severe postpartum hemorrhage.Methods:Patients hospitalized in a tertiary care center between 2007 and 2018 were included in the study.The records of cases were obtained from the hospital database,retrospectively.Maternal demographic data,morbidities or complications associated with BHGAL surgery,any additional haemostatic interventional or surgical procedures,preoperative admission and lowest postoperative haematocrit-hemoglobin values,blood products given,type of anaesthesia,intensive care unit(ICU)and length of hospital stay were recorded.In cases without surgical sterilization,future fertility and subsequent pregnancy outcomes were assessed for at least two years after operation.Information was obtained through face-to-face or telephone interviews with patients whose long-term fertility and subsequent pregnancy outcomes were assessed.Results:Sixty-eight patients with BHGAL surgery history were included in the study.26 Of 37 cases(70%)that did not undergo surgical sterilization had a desire for pregnancy after the surgery.Six of these cases(23%)were diagnosed with secondary infertility.The fertility rate of these cases was 77%,and subsequent pregnancy was detected in 20 women.A total of 25 pregnancies,including first and second pregnancies,developed,and 15 of these pregnancies resulted in term delivery,six preterm births,one stillbirth,and three abortions.Conclusions:The postoperative pregnancy rate was found to be higher than the rate of women with infertility problems,and this surgery does not seem to adversely affect pregnancy outcomes.This is a tertiary center experience and cohort studies with large patient series are needed.

Endovascular treatment of aortoiliac aneurysms: From intentional occlusion of the internal iliac artery to branch iliac stent graft

Approximately 20%-40% of patients with abdominal aortic aneurysms can have unilateral or bilateral iliac artery aneurysms and/or ectasia. This influences and compromises the distal sealing zone during endovascular aneurysm repair. There are a few endovascular techniques that are used to treat these types of aneurysms, including intentional occlusion/over-stenting of the internal iliac artery on one or both sides, the "bell-bottom" technique, and the more recent method of using an iliac branch stent graft. In some cases, other options include the "snorkel and sandwich" technique and hybrid interventions. Pelvic ischemia, represented as buttock claudication, has been reported in 16%-55% of cases; this is followed by impotence, which has been described in 10%-17% of cases following internal iliac artery occlusion. The bellbottom technique can be used for a common iliac artery up to 24 mm in diameter given that the largest diameter of the stent graft is 28 mm. There is a paucity of data and evidence regarding the "snorkel and sandwich" technique, which can be used in a few clinical scenarios. The hybrid intervention is comprised of a surgical operation, and is not purely endovascular. The newest branch stent graft technology enables preservation of the anterograde flow of important side branches. Technical success with the newest technique ranges from 85%-96.3%, and in some small series, technical success is 100%. Buttock claudication was reported in up to 4% of patients treated with a branch stent graft at 5-year follow-up. Mid- and short-term follow-up results showed branch patency of up to 88% during the 5-6-year period. Furthermore, branch graft occlusion is a potential complication, and it has been described to occur in 1.2%-11% of cases. Iliac branch stent graft placement represents a further development in endovascular medicine, and it has a high technical success rate without serious complications.

Effects of internal iliac artery embolization on systemic inflammatory response syndrome in dogs with simulatedpelvic-fracture combined with massive bleeding

Background: Pelvic fracture combined with massive bleeding(PFCMB) is a complex issue in clinical practice. Currently, the use of angiography and embolization for the treatment of PFCMB obtains good results. The aim of this study is to observe the effects of early internal iliac artery embolization on the systemic inflammatory response syndrome(SIRS) in dogs with simulated-pelvic-fracture combined with massive bleeding.Methods: Twenty adult dogs were randomly divided into an embolization group(EG) and a control group(CG). For the two groups, heart rate, respiratory rate and body temperature and other physiological variables were measured, and IL-6, TNF-α and arterial blood gas levels were monitored. These variables were assayed every 30 min until death in the CG, while dogs in the EG underwent arterial angiography after 60 min of modeling. The internal iliac artery was embolized on the injured side.Results: The average time to SIRS in the CG was 3.56 h, occurring at a rate of 90%(9/10) within 24 h, with a mortality rate of 50%(5/10); the average time to SIRS for the EG was 5.33 h, occurring at a rate of 30%(3/10) within 24 h, with a mortality rate of 10%(1/10). When SIRS occurred in the EG, the mean plasma IL-6 level was 52.66±7.38pg/ml and the TNF-ps, tα level was 11.45±2.72ng/ml, showing a significant difference with those of the CG(P<0.05). In the two grouhe respiratory rate and leukocyte levels were higher at each monitored time after modeling than those before modeling; the mean arterial pressure, levels of hemoglobin and oxygen partial pressure were significantly lower at each time point after modeling than those before modeling except for the mean arterial pressure at 0h in EG; the platelet levels at 4 and 8h were higher than those before modeling; and the differences were statistically significant(P<0.05). In the EG, the mean arterial pressure, heart rate, respiratory rate and hemoglobin levels at 2, 4 and 8h were lower than those at 0h; the levels of leukocytes, platelets and carbon dioxide partial pressure at 4 and 8h after modeling were higher than those at 0h, and the differences were statistically significant(P<0.05, P<0.01); in the CG after modeling, the mean arterial pressure, levels of hemoglobin and carbon dioxide partial pressure at 2, 4 and 8h were lower than those at 0h; the levels of heart rate and leukocytes were higher than those before modeling; the respiratory rate and platelet levels at 4 and 8h were higher than those at 0h; and the differences were statistically significant(P<0.05). The levels of the mean arterial pressure and hemoglobin at 4 and 8h and the p H values at 8h after modeling in the EG were significantly higher than those in the CG, while the heart rate and respiratory rate at 4 and 8h were significantly lower than those in the CG. The p H values at 8h after modeling were significantly lower than those of the other monitored times in the CG(P<0.05, P<0.01). The two groups had elevated levels of alkaline phosphatase after injury induction.Conclusion: Through the use of an on-spot interventional treatment cabin, early internal iliac artery embolization can control bleeding associated with pelvic fractures, delay the occurrence of SIRS, and improve the success rate of the treatment of pelvic fracture combined with bleeding.

Common iliac artery occlusion with small intestinal transection caused by blunt abdominal trauma: A case report and review of the literature

BACKGROUND Most major abdominal vascular injuries are caused by penetrating injuries.A common iliac artery occlusion caused by blunt force trauma is rare,and very few cases have been reported.Because of this low incidence,atypical symptoms,and frequent association with other severe injuries,the proper diagnosis tends to be missed or delayed.The gold standard for diagnosis is angiography,and treatment remains a challenge.CASE SUMMARY We report here the unusual case of a common iliac artery occlusion caused by blunt abdominal compressive trauma,with transection of the small intestine.At presentation,the patient(a 56-year-old man)complained of pain and numbness in the left lower extremity and severe pain in the whole abdomen.Physical examination showed total abdominal tenderness with evidence of peritoneal irritation.The left lower limb was pulseless and cold.Abdominal computed tomography examination revealed digestive tract perforation,and abdominal computed tomography angiography showed left common iliac artery occlusion.The patient was treated successfully by anastomosis of the intestine,percutaneous transluminal angioplasty,and stenting.The patient was followed for more than 11 mo after the operation and showed a good recovery.CONCLUSION Patients with abdominal trauma should be suspected of having major vascular injury.Individualized treatment strategies are needed for this condition.

Spontaneous Coronary Artery Dissection with Iliac Artery Dissection: A Case Report and Literature Review

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome or sudden cardiac death.It often occurs in females with no conventional cardiovascular risk factors.Bilateral iliac artery dissection is also a rare disease.This case report describes a patient with spontaneous coronary artery dissection and iliac artery dissection.The authors believe that a conservative approach could be used as an effective therapy for a clinically stable patient.

Ureteral-artificial iliac artery fistula:A case report

BACKGROUND Ureteral-iliac artery fistula is a rare disease resulting from the pathological connection between the ureter and iliac artery,with artificial iliac artery-ureteral fistula being rarer.Iliac artery ureteral fistula is challenging to diagnose,and the misdiagnosis and mortality rates are high.CASE SUMMARY A case of artificial iliac artery ureteral fistula was reported in this paper.The patient was a 69-year-old male with paroxysmal painless hematuria.The artificial iliac artery ureteral fistula was diagnosed by angiography.The hematuria was stopped after intravascular embolization,and no bleeding occurred after 6 months of follow-up.CONCLUSION Ureteral arterial fistula should be considered when inconspicuous hematuria with previous iliac vessels is encountered in addition to local ureteral surgery history.A rapid endovascular approach is recommended for fistula identification.

A Polymer Coated Cicaprost-Eluting Stent Increases Neointima Formation and Impairs Vessel Function in the Rabbit Iliac Artery

Drug-eluting stents have been successful in reducing in-stent restenosis but are not suitable for all lesion types and have been implicated in causing late stent thrombosis due to incomplete regeneration of the endothelial cell layer. In this study we implanted stents coated with cicaprost, a prostacyclin analogue with a long plasma half-life and antiproliferative effects on vascular smooth muscle cells, into the iliac arteries of rabbits. At 28-day follow-up we compared neointima formation within the stented vessels and vascular function in adjacent vessels, to assess if cicaprost could reduce restenosis without impairing vessel function. Arteries implanted with cicaprost eluting stents had significantly more neointima compared to bare metal stents. In adjacent segments of artery, endothelium-dependent relaxation was impaired by the cicaprost-eluting stent but vasodilation to an endothelium-independent vasodilator was maintained. We conclude that the presence of the polymer and sub-optimal release of cicaprost from the stent may be responsible for the increased neointma and impaired functional recovery of the endothelium observed. Further experiments should be aimed at optimising release of cicaprost and exploring different stent polymer coatings.

Role of Anterior Division of Internal Iliac Artery Ligation in Refractory Postpartum Haemorrhage—A Tertiary Care Hospital Based Study

Objective: Postpartum haemorrhage (PPH) is one of the important obstetrical emergencies and a leading cause of maternal morbidity and mortality. According to the World Health Organization, postpartum haemorrhage constitutes 25% of all maternal deaths worldwide. In situations where medical line of management fails to control postpartum haemorrhage, anterior division of internal iliac artery ligation can play an important role as a lifesaving and fertility preserving surgical procedure. Keeping this in mind, our study aimed to analyze indications and efficacy of anterior division of Internal Iliac artery ligation in the form of uterine salvage and saving maternal life. Study design: This was a retrospective study carried out in the Department of Obstetrics and Gynaecology, Government Medical College, Aurangabad during the period of July 2014-January 2016. A total of 57 cases that had undergone ligation of anterior division of internal iliac artery were included in the study and different indications and efficacy were studied. Results: Atonic PPH (52.63%) leads the list of indications for ligation anterior division of internal iliac artery ligation followed by traumatic (19.29%), adherent placenta (12.2%), mixed variety (10.52%) and coagulopathy (5.26). Maximum efficacy in terms of preserving fertility and saving maternal life was 73.33% and 93.3% respectively in atonic PPH. Overall efficacy of this procedure in terms of uterine salvage was 54.38% and in terms of saving maternal life was 87.71%. Conclusion: Anterior division of IIAL was effective method in controlling refractory PPH, reducing morbidity and preserving uterus and future fertility. It is safe life saving procedure at experienced hands.

Long Term Clinical and Angiographic Outcome Following Percutaneous Transluminal Angioplasty and Stent Placement for Iliac and Femoral Artery Stenosis

Objective This study reportsthe initial and late results of percutaneous transluminal angioplasty (PTA) and intravascular stenting for atherosclerotic stenosis of the iliac and femoral arteries. Methods and Results From December 1994 to March 1997, we performed iliac and femoral artery angioplasty and primary intravascular stent placement in 37 vessel of 33 patients (19 men and 14 women; mean age, 70. 5 years). A total of 43 self - expanding Wallstents (Boston, Inc. ) were deployed. All patients underwent angioplasty and stent placement successfully. Clinical follow - up was available for all patients at a mean of 26±14months. All patient clinical is-chemic category (claudication or rest pain) was improved. Angiographic follow - up was completed for 17 of 23 patients at a mean follow-up of 10±5 months, The iliac artery restenosis rate was 0(0/8). The femoral artery restenosis rate was 33 % (3/9), All 3 patients underwent repeat balloon angioplasty successfully. Conclusion The iliac and femoral arteries can be performed and reasonable early and late patency rates.

Selective Internal Iliac Artery Oxaliplatin Infusion： Another Facultative Treatment to Unremitting Hematuria in Stage T4 Bladder Carcinoma

OBJECTIVE To observe and evaluate the value of utilizing selective internal iliac artery infusion and selective internal iliac artery embolization for the treatment of unremitting gross hematuria of stage T4 bladder carcinoma. METHODS Fifty-eight stage T4 bladder carcinoma patients were selected. The patients were grouped to the TAI group and the TAE group. The main symptom of hemorrhage was gross hematuria. None of the patients in our study could receive trunk embolization. The infusion plan was oxaliplatin （100 mg/m2） and epirubicin （EPI 50mg/m2）. Embolization was done with coils or strips of gelatin sponge. The duration of gross hematuria was observed. Routine urinalysis and routine blood examination were performed. EORTC QLQ-C30 was used to evaluate the quality of life before and after treatment. RESULTS Gross hematuria and hematuria by light microscope in all patients were reviewed. Resolution time of gross hematuria in the TAI group was 6.7 ± 1.8 days and that in the TAE group was 3.5 ± 0.7 days. The changes in routine urianlysis, routine blood examination and EORTC QLQ-C30 are shown in Figs.l-3. Gross hematuria disappeared in both groups within 7 days after treatment, but the time for the gross hematuria to resolve in the TAE group was much less than that in TAI group （t = 2.51, P 〈 0.01）, and there were no significant differences in the 7th and 21st day between the 2 groups. On the 90th day, the number of erythrocytes in the urine was near 30, close to gross hematuria. The EORTC QLQ-C30 scores decreased after interventional therapy in both groups, which means that quality of life was increased, but there were no significant differences between the 2 groups. CONCLUSION Selective internal iliac artery infusion and selective internal iliac artery embolization are safe, and, in our study, therapeutic efficacy was satisfactory in treating unremitting gross hematuria of stage T4 bladder carcinoma in patients who could not receive trunk embolization. TAE can stop gross hematuria in the short term, but it can be used just once and the long-term therapeutic effect is not satisfactory. TAI had a therapeutic effect similar to TAE, but for a shorter duration, and TAI can be performed multiple times. TAI is one of the facultative treatments for treating gross hematuria of stage T4 bladder carcinoma.

Management of retroperitoneal sarcoma involving the iliac artery:Single-center surgical experience

BACKGROUND Management of retroperitoneal sarcoma(RPS)involving the iliac artery is challenging and requires the concerted efforts of multidisciplinary team(MDT)members during surgical treatment.AIM To summarize the clinicopathologic features of RPS involving the iliac artery and our retroperitoneal soft tissue tumor MDT surgical experience.METHODS In this retrospective study,15 patients with RPS involving the iliac artery who underwent surgery at our retroperitoneal soft tissue tumor center from July 2004 to June 2020 were analyzed.Statistical analyses were performed by Student’s ttest with SPSS 16.0.RESULTS Complete tumor resection(R0/R1)and iliac artery reconstruction were achieved in all 15 patients.All the operations were successful,with no serious complications or perioperative death.Resection with bilateral iliac artery reconstruction required a higher intraoperative blood transfusion volume than resection with unilateral iliac artery reconstruction.Recurrent cases were more likely to bleed and required a higher blood transfusion volume than primary cases.As of January 2021,11 patients were alive,and 4 had died.Local recurrence occurred in two patients,one of whom developed liver metastasis.CONCLUSION Resection of RPS involving iliac vessels is feasible and effective when performed by MDT members.Iliac artery oncovascular resection and reconstruction are key to a successful operation.Adequate blood preparation is important for successful completion of surgery.

Internal iliac artery ligation as a damage control method in hemodynamically unstable pelvic fractures:A systematic review of the literature

Purpose:Internal iliac artery ligation(IIAL)has been used as a damage control procedure to treat hemodynamically unstable pelvic fracture for many years.However,there is ongoing debate regarding the effectiveness and safety of this hemostatic method.Therefore,we performed a systematic literature review to assess the efficacy and safety of IIAL for pelvic fracture hemostasis.Methods:Three major databases,PubMed,Embase,and Google Scholar,were searched to screen eligible original studies published in English journals.Two reviewers independently read the titles,abstracts,and full texts of all literature.Articles were included if they reported the use and effects of IIAL.Results:A total of 171 articles were initially identified,with 22 fully meeting the inclusion criteria.Among the analyzed cases,up to 66.7%of patients had associated abdominal and pelvic organ injuries,with the urethra being the most frequently injured organ,followed by the bowel.The outcomes of IIAL for achieving hemostasis in pelvic fractures were found to be satisfactory,with an effective rate of 80%.Hemorrhagic shock was the leading cause of death,followed by craniocerebral injury.Notably,no reports of ischemic complications involving the pelvic organs due to IIAL were found.Conclusion:IIAL has a good effect in treating hemodynamically unstable pelvic fracture without the risk of pelvic organ ischemia.This procedure should be considered a priority for hemodynamically unstable pelvic fracture patients with abdominal organ injuries.

Outflow reconstruction with arterial patch in domino liver transplantation: a new technical option

Domino liver transplantation（LT）, using livers from familial amyloidotic polyneuropathy（FAP） patients, is a well described technique useful to expand donor pool. One of the main difficulties of this type of LT arises from the necessity to share the vascular pedicles between the graft and the donor. The most important challenge resides in restoring a proper hepatic venous outflow in the FAP-liver recipient.This is specially challenging when using the piggy-back technique, because the hepatic stumps may be too short. To overcome this issue, surgeons explored several techniques using different types of venous grafts. We describe a new technical option by using an arterial graft from the deceased donor. By using both iliac arteries a long graft is created and sutured as needed to the hepatic vein stump. We describe herein this new technique employed in a domino liver recipient who underwent retransplantation for ischemic cholangitis. The procedure was performed using the piggy-back technique; the venous stump of the FAP liver was reconstructed with the arterial graft. The patient had uneventful postoperative and mid-term hepatic function, and anastomosis was patent 24 months after LT.

Internal Iliac Pseudoaneurysm Rupture Attributed to Perforated Hartmann’s Pouch Diagnosed on CT

Rupture is a rare but disastrous complication of an arterial aneurysm. Intraabdominal abscess in association with iliac artery aneurysm is uncommon but can predispose to aneurysm rupture. We report the Computed Tomography (CT) findings of an internal iliac artery pseudoaneurysm formed by a pelvic abscess attributed to the perforation of the patient’s Hartmann’s pouch. Rupture of the pseudoaneurysm resulted in the patient’s death.
