Robotic-assisted simple prostatectomy with clamping of bilateral hypogastric arteries.

To present a case of laparoscopic robotic-assisted simple prostatectomy with temporary clamping of the bilateral hypogastric arteries. A 74-year-old patient with large prostatic adenoma (> 80 ml) underwent robotic-assisted laparoscopic transvesical adenoma enucleation according to Sotelo's technique. The hypogastric arteries were isolated just below the ureteral cross with the iliac vessels and bilaterally occluded for 12 minutes during enucleation of the adenoma. The patient's pain was mild after surgery and he required short-term analgesics and antibiotic prophylaxis. Blood loss was 80 ml. The transient occlusion of the internal iliac arteries is a proven maneuver to reduce bleeding during pelvic surgery. We propose the temporary clamping of the bilateral internal iliac arteries as a safe and rapid surgical maneuver to reduce the intraoperative risk of bleeding, especially when performing first procedures.

Embolization of the Internal Iliac Artery Before EVAR: Is It Effective? Is It Safe? Which Technique Should Be Used?

To assess the clinical outcomes of internal iliac artery (IIA) embolization before endovascular aneurysm repair (EVAR). Between 2002 and 2011, 88 patients underwent IIA embolization prior to EVAR. Sixty-five patients underwent unilateral and 23 underwent bilateral IIA embolization. A total of 111 IIAs were embolized: 56 were embolized with coils, 41 with Amplatzer plugs, and 14 with a combination of embolic agents. The outcomes were assessed retrospectively by reviewing medical records and follow-up imaging. IIA embolization was technically successful in 95.7% of cases. Type 2 endoleak from previously embolized IIAs was seen in 4 cases, and in 1 case this was significant necessitating re-intervention. Buttock claudication was reported in 38% of cases, whereas new onset erectile dysfunction occurred in 10% of cases. No severe ischemic complications, such as spinal cord ischaemia or buttock necrosis, were reported. Analysis comparing unilateral versus bilateral embolization, simultaneous versus sequential embolization, and the type of embolic material used showed no statistical significance. IIA embolization is technically successful and effective in preventing significant type 2 endoleak in the majority of cases. It is a relatively safe procedure without major complications, but the incidence of buttock claudication and erectile dysfunction remain relatively high, and patients should be consented appropriately. There is no significant benefit for adopting a particular embolization technique, but there is a tendency towards reduced pelvic ischaemia with proximal embolization. Four cases of type II endoleak occurring after technically successful IIA embolization supports the school of thought that IIA should be embolized prior to coverage and extension of the distal landing zone.

OBJECTIVES: Evaluation of a new surgical technique to prevent postpartum haemorrhage during cesarean section for major degree placenta previa - A comparative analysis. METHODS: This study was conducted at tertiary care hospital (JNM, NSGH, CN) at Kalyani Nadia, West Bengal, India from the period January 2006 to December 2011. Sixty (60) cases diagnosed to be having major degree placenta previa, undergoing LSCS operation, were selected for this study in two groups for comparative analysis. Group A(N-30) - New surgical technique(Dutta 's) institute in a stepwise manner = delivery of baby > bilateral uterine artery ligation by chromic catgut no-1 suture >injection tranexamic acid (1000mg) IM > injection oxytocin in intravenous infusion (10 units 30 drop /min in 500 ml of 5% dextrose)>delivery of placenta and membranes> checked properly if any tear or laceration in placental site > closure of uterine wound by chromic catgut no 1 in two layers after securing bleeding from placental bed >closure of abdomen in layers . Group B (N-30) (traditional method) = delivery of baby> delivery of placenta and its membrane > injection oxytocin in intravenous infusion (10 units 30 drop /min in 500 ml of 5% dextrose ) > surgical intervention either by bilateral uterine artery or internal iliac artery ligation or cesarean hysterectomy or underlying interrupted suture to control post operative haemorrhage > closure of uterine wound by chromic catgut no 1 suture in two layers > closure of abdomen in layers. RESULTS: It was observed from this comparative analysis that in group B intra operative blood loss > 500cc -18 (60%), cesarean hysterectomy- 6(20%) and bilateral internal iliac artery ligation- 4 (13.3%) were found to be increased as compared to group A. Maternal mortality was found to be high in group B -5(16.6%) as compared to group A- nil. Maternal morbidity was also found to be increase in group B- 13(43.3%) cases as compared to group A- 4(13.3%). Subsequent menstrual cycles were found to be normal in group A - 20(90%) indicating non effect on gonadal function. CONCLUSION: This comparative analysis showed that by advocating this noble approach

Management of major degree placenta previa during LSCS operation - a new surgical technique (Dutta's)

Objectives: Evaluation of a new surgical technique (Dutta’s) to prevent postpartum hemorrhage due to major degree placenta previa during cesarean section. Methods:This study was conducted at tertiary care hospital(JNM,& NSGH) at Kalyani, Nadia, West Bengal, India from the period January 2004 to December 2009.Ninty four (94) cases diagnosed to be having major degree placenta previa, undergoing LSCS operation, were selected for this study. New surgical technique(Dutta’s) was adopted in a stepwise manner = delivery of baby > bilateral uterine artery ligation by chromic catgut no-1 suture >injection tranexamic acid (1000mg) IM > injection oxytocin in intravenous infusion(10 units 30 drop /min in 500 ml of 5% dextrose)>delivery of placenta and membranes> checked properly if any tear or laceration in placental site > closure of uterine wound was done after securing bleeding from placental bed >closure of abdomen in layers by polyglycolic acid no 1 suture. Results: It was observed from this study that good effectiveness to control bleeding and intra operative blood loss less than 300cc were seen in 89(94.68%) cases respectively. Six (6.3%) cases required underlying interrupted suture for bleeding from placental bed. Subtotal cesarean hysterectomy was advocated in 3(3.28%) cases due to failure to control uterine atony. Immediate post operative bleeding less than 200c.c was found in 81 (86.16%) cases. Maternal mortality was found to be absent. Maternal morbidity was seen in 12(12.76%) cases. Subsequent menstrual cycles were found to be normal in 80(87.91%) cases and repeated pregnancy was observed in 26(28.57%) cases indicating non effect on gonadal function. Conclusion: Dutta’s new surgical technique during LSCS for major degree placenta previa was found to be simple, safe and quick procedure. It reduces perfusion pressure, permits time for further steps, thereby avoiding unnecessary ligation of bilateral internal iliac arteries and cesarean hysterectomy. Maternal mortality and morbidity were also found to be reduced. This technique is suitable for rural based hospital in absence of adequate blood transfusion facility.DOI: http://dx.doi.org/10.3126/ajms.v4i2.7958 Asian Journal of Medical Sciences 4(2013) 1-7

Direct sonographic-guided superior gluteal artery access for treatment of a previously treated expanding internal iliac artery aneurysm

Isolated internal iliac artery aneurysms are relatively uncommon compared with all aortoiliac aneurysms. Transcatheter treatment with coil embolization is an attractive noninvasive alternative to surgical resection. However, if the aneurysm is insufficiently treated with only proximal coil embolization without concurrent embolization of distal runoff vessels, there is a risk of aneurysm expansion from retrograde collateral flow. We present a case of previously treated internal iliac aneurysm that underwent late rapid expansion. Due to occlusion of the internal iliac artery, direct sonographic-guided puncture of the superior gluteal artery was made in order to access the aneurysm. We believe this is the first reported case of such treatment.

OBJECTIVE: To evaluate utility and outcome of emergency bilateral internal iliac artery ligation (BIIAL), as life saving measure in severe post partum hemorrhage (PPH). MATERIAL AND METHOD: Between June2003 to May 2012, a total of twenty four patients of severe PPH were managed with emergency BIIAL with or without hysterectomy. All patients were in shock and we were called directly in operation theatre (O T). The Patients were managed post operatively in obstetric intensive care unit (ICU) with ventilator and inotropic supports. RESULT: We had one (4.16%) mortality with successful outcome in 23(95.83%) patients. In 8 patients (33.33%) hysterectomy has already been performed before we could intervene. One (4.16%) patient develop pulmonary embolism but was saved. CONCLUSION: Emergency BIIAL is an life saving procedure and should be learned and managed by all surgeon in severe PPH

Preservation of Internal Iliac Arterial Flow during Endovascular Aortic Aneurysm Repair Using the “Sandwich” Technique

Conventional endovascular aneurysm repair (EVAR) of an abdominal aortic aneurysm (AAA) requires adequate graft seal proximally in the infrarenal aorta and distally in the common or external iliac arteries. When possible, sealing in the common iliac artery is performed to maintain perfusion to the internal iliac artery. Approximately 40% of AAAs have associated common iliac artery aneurysms that would require an external iliac seal zone and ipsilateral internal iliac artery embolization to prevent a type II endoleak. Concurrent or staged internal iliac artery occlusion may result in pelvic ischemia, which commonly manifests as buttock claudication or, in men, impotence. Uncommon but more serious consequences include colonic and spinal artery ischemia. Coverage or embolization of a single internal iliac artery is generally well tolerated. There is a varied incidence (20 to 50%) of clinically significant buttock claudication that tends to improve over time resulting in ∼10% incidence of buttock claudication at 1 year with single hypogastric artery embolization. Published case series and individual reports of bilateral internal iliac artery embolization demonstrate that bilateral hypogastric occlusion appears safe, although there is an increased risk of serious complications that may be life threatening. Most physicians attempt to preserve flow to a single internal iliac artery whenever possible. Various methods have been described to preserve internal iliac artery flow during EVAR. Investigational iliac branched devices (not currently approved by the Food and Drug Administration [FDA]), hybrid surgical revascularization of the internal iliac artery, physician modification of existing endografts, and, more recently, parallel endografting with the “sandwich” technique are some of the ways flow can be preserved to the hypogastric artery. The sandwich endograft technique involves placing two endografts side by side into an existing iliac limb to create an off-the-shelf bifurcated component to preserve flow to both the internal iliac and external iliac arteries. This technique has been gaining acceptance as a viable method for preservation of flow to at least a single internal iliac artery allowing for expansion of anatomy suitable for EVAR with the use of commercially available endograft components, albeit in an off-label manner. The sandwich technique is applicable to a variety of endograft designs, although the steep bifurcation of most endografts requires axillary or brachial artery access to deliver a stent into the preserved internal iliac artery. The bifurcation-sparing nature of the Endologix AFX (Endologix, Irvine, CA) endograft allows for this technique to be performed from an entirely femoral approach and has become our preferred approach for internal iliac preservation during EVAR when the anatomy is appropriate.

Successful Endovascular Repair of Ruptured Isolated Bilateral Internal Iliac Artery Aneurysms

IntroductionDue to their anatomic location, internal iliac artery aneurysms are difficult to treat surgically. An endovascular approach can be helpful, even in ruptured cases. ReportWe report a 71-year-old male with ruptured isolated bilateral internal iliac artery aneurysms. The aneurysms were treated with embolisation of the branching arteries of the bilateral internal iliac arteries followed by placement of a stent graft covering the orifice of the bilateral internal iliac arteries. The patient tolerated this procedure well. DiscussionEven in patients with ruptured aneurysms, endovascular treatment for internal iliac artery aneurysms can be a good treatment option.

Challenging the Evidence for Pre-emptive Coil Embolisation of the Internal Iliac Artery during Endovascular Aneurysm Repair

We retrospectively analysed the results of a strategy in which coverage of the internal iliac artery (IIA) during endovascular aneurysm repair (EVAR) was routinely performed without coil embolisation. From January 2010 until May 2012, 32 patients (96.9% men; mean age 73.0 years, range 52-89 years) underwent EVAR with stent grafts extended into the external iliac artery (EIA), all without prior coil embolisation. Aneurysm morphology was determined on preoperative computed tomography (CT) images. During follow-up, patients were interviewed about buttock claudication, and the occurrence of endoleaks and evolution of aneurysm diameter were recorded. At baseline, the mid-common iliac artery (CIA) diameter was 33.5 ± 16.8 mm and seven patients presented with ruptured aneurysms. Mean follow-up was 14.3 ± 7.4 months. There were eight deaths, none related to IIA coverage. Buttock claudication occurred in seven (22.6%) patients, which persisted after 6 months in two cases of bilateral IIA coverage. No Type-I or -II endoleaks occurred related to IIA coverage. Aneurysm growth was not observed. Endovascular treatment of aortoiliac and iliac aneurysm without pre-emptive coil embolisation of the IIA appears safe and effective. No IIA-related endoleaks or re-interventions occurred in our series. This approach saves operating time, contrast load and costs and may reduce complications. However, a larger population and longer follow-up is required to confirm our findings.

Endovascular repair of bilateral iliac artery aneurysm with branched iliac stents: case report and review of the current literature

Common iliac artery aneurysm (CIA) often occurs in conjunction with an abdominal aortic aneurysm (AAA), which extends into one or both CIAs in 20% to 30% of patients. Conventional endovascular treatment includes coil embolization of the internal iliac artery (IIA), followed by extension of the main bifurcated AAA stent-graft into the external iliac artery. However, complications from intentional occlusion of unilateral or bilateral IIAs are frequent and sometimes serious. Several methods try to preserve the unilateral or bilateral IIA. Here we report a case of concomitant bilateral CIA and AAA successfully treated with bilateral branched iliac stent-grafts.

Pathological Findings in a Case of Failed Uterine Artery Embolization for Placenta Previa

The reported success rate of uterine artery embolization (UAE) for obstetrical hemorrhage is more than 90%. We experienced a case of failed UAE for postpartum hemorrhage, although an embolic particle was found pathologically in the uterine vessels without coagulation. A 42-year-old woman (gravida 7, para 2) with placenta previa had genital bleeding at 35 weeks of gestation, and cesarean section was performed. We immediately added UAE aiming to reduce massive bleeding after the cesarean section, successful embolization of the bilateral uterine arteries and internal iliac arteries were confirmed by angiography regardless the vital sign was recovered with an appropriate amount of transfusion; the massive bleeding recurred after 1 hour of UAE. Hysterectomy was performed and pathological findings of the uterus showed that there was no coagulation in the vessels, which was supposed to be observed by the effect of gelatin sponge. In addition, despite the fact that no coagulation was found, only one gelatin sponge was found in 16 slices of the uterine wall specimens. We speculate that thrombotic materials were caught in vasoconstricted vessels triggered by hypovolemic shock due to acute blood loss, and then the gelatin sponge could be washed out after recovering to normalized circulation status leading to recurrent massive hemorrhage.

Prompt Diagnosis and Treatment of Uterine Arcuate Artery Pseudoaneurysm: A Case Report and Review of Literature

Post-partum haemorrhage is a major determinant of maternal mortality. Traditionally, cases of post-partum haemorrhage caused by arterial injuries were managed by caesarean hysterectomies or bilateral internal iliac artery ligations. The diagnosis of aneurysms or arteriovenous malformations of uterine artery are often missed. Uterine curettage, caesarean section or vaginal delivery can result in uterine vascular anomalies like pseudo aneurysms, arteriovenous malformations, arteriovenous fistula and rupture of uterine vessels. Colour Doppler ultrasound pelvis allows detection of these vascular abnormalities. It helps in differentiating the vascular abnormalities that require embolization from non-vascular abnormalities which can be managed by uterine curretage. Vessel malformations can be treated safely with transcatheter uterine artery embolization, but they can develop disastrous consequences with inadvertent uterine curettage. Transcatheter uterine artery embolization after pelvic angiography is the treatment of choice for uterine artery malformations and it has the advantage of preserving the reproductive capacity. We recommend a routine use of colour Doppler ultrasound pelvis for evaluation of abnormal uterine bleeding.

Trauma-associated bleeding from the bilateral internal iliac arteries resolved with angiographic embolization

Pelvic fracture is associated with high mortality. The management of major pelvic injuries remains one of the most important issues in modern trauma care. A 39-year-old male patient presented at the emergency department after being hit with a 500 kg load. His general condition was average with unstable vital signs. Pelvic tomography revealed fractured bone structure, thickening secondary to hematoma in both iliopsoas muscles, and hemorrhage-related active extravasation in the left internal iliac trace. The patient's hemodynamics worsened despite fluid and blood replacement, and angiographic embolization was scheduled. Bilateral embolization of the iliac artery was performed. Control angiography confirmed that full embolization was established. The patient was monitored in intensive care, but expired after three days due to acute kidney failure, disseminated intravascular coagulation, and multi-organ failure. Angiographic embolization is a technique improves hemorrhage control in pelvic trauma but can also increase risk of complications such as ischemia and necrosis.

Placenta previa and percreta with massive genital bleeding in the first trimester of pregnancy: A case report

A 40-year-old woman with a history of cesarean section and 3 episodes of uterine curettage for spontaneous or induced abortion presented with massive genital hemorrhage in the ninth week of gestation; she was treated with red cell concentrate and fresh frozen plasma transfusion. She was admitted to our hospital at the 11th week of gestation for continuous genital hemorrhage and cervical shortening (20 mm). Ultrasonography revealed placenta previa totalis. A lowlying gestational sac in early pregnancy, vascular lacunae, and an obscured retroplacental sonolucent zone indicated placenta percreta; magnetic resonance imaging showed similar findings. Owing to placenta percreta, uterus preservation was considered impossible. Elective cesarean section followed by total hysterectomy was performed at the 37th week of gestation, with bilateral internal iliac artery balloon catheter occlusion for reducing blood loss. The perioperative blood loss was 2,835 mL, for which the patient received blood transfusion. The postoperative course was uncomplicated.

Two Cases of Successful Inferior Mesenteric Artery Preservation with Bare Metal Stent in Endovascular Iliac Artery Aneurysm Repair

During endovascular aneurysm repair, interruption of the inferior mesenteric artery (IMA) or internal iliac arteries (IIAs) is thought to be associated with postoperative pelvic ischemic complications, including ischemic colitis. However, preserving the IIA does not guarantee protection against ischemic colitis. We herein report two cases of bilateral common iliac artery aneurysms, which were treated with bifurcated stent grafting with bilateral IIA embolization and simultaneous IMA stent placement to prevent colonic ischemia. This procedure might be effective for both preserving the IMA circulation and preventing ischemic colitis.

Angiographic Embolization of a Postpartum Vulvovaginal Hematoma in a Patient with Situs Inversus Totalis: An Effective Second-Line Treatment

Situs inversus totalis is a rare congenital anomaly where asymmetrical positioning of internal organs may affect the surgical and radiological management of certain conditions. Vulvovaginal hematoma is a life-threatening complication of vaginal delivery whose primary treatment usually consists of incision and drainage of the hematoma and ligation of the responsible vessels, followed by wound packing. Failure of these measures to control the bleeding was previously considered as an indication for laparotomy to perform bilateral hypogastric artery ligation and, if needed, a hysterectomy. Relative to major abdominal surgery, selective percutaneous angiographic embolization offers considerable advantages and significant less morbidity. Indeed, angiographic embolization is routinely used as a measure to control refractory pelvic bleeding, though the literature and experience in women with situs inversus totalis are scarce. In this paper, we report a case of postpartum vulvovaginal hematoma in a patient with situs inversus, refractory to conventional treatment, where arteriographic embolization was successfully used to control the bleeding. The management of this obstetrical complication and the use of this minimally invasive technique are also reviewed. To the best of our knowledge, this is the first report in the literature describing the feasibility of this technique in a patient with situs inversus totalis.

Impotence due to External Iliac Steal Syndrome: Treatment with Percutaneous Transluminal Angioplasty and Stent Placement

We report a case of erectile dysfunction caused by external iliac artery occlusion, associated with pelvic steal syndrome; bilateral internal iliac arteries were patent. The patient stated that he had experienced erectile dysfunction at similar times along with claudication, but he did not mention it before angiography. He expressed that the erectile dysfunction did not last long and that he felt completely okay after the interventional procedure, in addition to his claudication. Successful treatment of the occlusion, by percutaneous transluminal angioplasty and stent implantation, helped resolve erectile dysfunction completely and treat the steal syndrome.

Preclinical report on allogeneic uterus transplantation in non-human primates

Is it possible to perform allogeneic uterus transplantation (UTx) with a donation from a live donor in a non-human primate species and what immunosuppression is needed to prevent rejection? Allogeneic UTx in the baboon is a donor- and recipient-safe surgical procedure; immunosuppression with induction therapy and a triple protocol should be used. UTx may become a treatment for absolute uterine factor infertility. Autologous UTx models have been developed in non-human primates with reports on long-term survival of the uterine grafts. STUDY DESIGN, SIZEAND DURATION: This experimental study included 18 female baboons as uterus donors and 18 female baboons as uterus recipients. The follow-up time was 5-8 weeks. Uterus retrieval was performed with extended hysterectomy including bilateral uterine and internal iliac arteries and ovarian veins. After UTx, with vascular anastomoses unilateral to the internal iliac artery and the external iliac vein, the uterus recipients received one of the following: no immunosuppression (n = 4); monotherapy (oral slow release tacrolimus) (n = 4) or induction therapy (antithymocyte globulin) followed by triple therapy (tacrolimus, mycophenolate, corticosteroids; n = 10). Surgical parameters, survival, immunosuppression and rejection patterns were evaluated. The durations of uterus retrieval and recipient surgery were around 3 and 3.5 h, respectively. The total ischemic time was around 3 h. All the recipients and the donors survived the surgery. All the recipients presented rejection to some extent within the first weeks following UTx. In one recipient, the uterus was of normal appearance at the end of the study period. In spite of occasional high (>60 ng/ml) blood levels of tacrolimus, there was no evidence of nephrotoxicity. This initial non-human primate allogeneic UTx study indicates that further research is needed to optimize immunosuppression protocols in order to avoid uterine rejection. The findings suggest that allogeneic UTx in primate species is feasible but continued work on this issue is needed. The study was funded by the Swedish Research Council, ALF University of Gothenburg, Hjalmar Svensson Foundation and by Jane and Dan Olsson Research Foundation. The authors do not have any competing interest.

Preliminary results of the first human uterus transplantation from a multiorgan donor

To describe the first-year results of the first human uterus transplantation case from a multiorgan donor. Case study. University hospital. A 21-year-old woman with complete müllerian agenesis who had been previously operated on for vaginal reconstruction. Uterus transplantation procedure consisting of orthotopic replacement and fixation of the retrieved uterus, revascularization, end to site anastomoses of bilateral hypogastric arteries and veins to bilateral external iliac arteries and veins was performed. Resumption of menstrual cycles. The patient had menarche 20 days after transplant surgery. She has had 12 menstrual cycles since the operation. We have described the longest-lived transplanted human uterus to date with acquirement of menstrual cycles.
