1/16. Treatment of iatrogenic previable premature rupture of membranes with intra-amniotic injection of platelets and cryoprecipitate (amniopatch): preliminary experience.OBJECTIVE: Our aim was to describe the treatment of iatrogenic previable premature rupture of membranes with the intra-amniotic injection of platelets and cryoprecipitate (amniopatch). STUDY DESIGN: patients with iatrogenic previable premature rupture of membranes and without evidence of intra-amniotic infection underwent transabdominal intra-amniotic injection of platelets and cryoprecipitate through a 22-gauge needle. The study was approved by the Institutional review Board of St Joseph's Hospital in Tampa, florida, and all patients gave written informed consent. RESULTS: Seven patients with iatrogenic preterm premature rupture of membranes underwent placement of an amniopatch. Membrane sealing was verifiable in 6 of 7 patients. Three patients had iatrogenic preterm premature rupture of membranes after operative fetoscopy, 3 cases were after genetic amniocentesis, and 1 was after diagnostic fetoscopy. Three pregnancies progressed well, with restoration of the amniotic fluid volume and no further leakage. Two patients had unexplained fetal death despite successful sealing. One case of bladder outlet obstruction had no further leakage, but oligohydramnios persisted and did not allow unequivocal documentation of sealing. One patient miscarried from twin-twin transfusion, but the amniotic cavity was sealed. CONCLUSIONS: Iatrogenic preterm premature rupture of membranes can be treated effectively with an amniopatch. The technique is simple and does not require knowledge of the exact location of the defect. Unexpected fetal death from the procedure may be attributable to vasoactive effects of platelets or indigo carmine. Although the appropriate dose of platelets and cryoprecipitate needs to be established, the amniopatch may mean that iatrogenic preterm premature rupture of membranes no longer needs to be considered a devastating complication of pregnancy.- - - - - - - - - - ranking = 1keywords = seal (Clic here for more details about this article) |
2/16. Tandem intracranial stent deployment for treatment of an iatrogenic, flow-limiting, basilar artery dissection: technical case report.OBJECTIVE AND IMPORTANCE: Intimal dissection constitutes one of the complications associated with angioplasty of intracranial vessels. We present a case of iatrogenic dissection of the entire basilar artery, which was induced by angioplasty and stenting of symptomatic, focal, intracranial vertebral artery stenosis, and its successful treatment with tandem deployment of a downstream stent. CLINICAL PRESENTATION: A 61-year-old, hypertensive, renal transplant recipient presented with orthostatic vertebrobasilar insufficiency that was refractory to medical management, including anticoagulation therapy. Angiography revealed an occluded right vertebral artery and focal, high-grade, left intracranial vertebral artery stenosis. magnetic resonance imaging showed multiple posterior fossa infarctions. The left intracranial vertebral artery stenosis was successfully treated with primary stent deployment and balloon angioplasty, with symptom resolution. On postprocedure Day 2, the patient noted worsening right hemiparesis. INTERVENTION: Subsequent angiography revealed a flow-limiting, windsock-type, basilar artery dissection beginning at the distal end of the left vertebral artery stent and extending to the origin of the left posterior cerebral artery. A tandem stent was navigated intracranially and deployed past the first one, successfully sealing the dissection inflow zone and reconstituting normal flow to the top of the basilar artery. A clinical follow-up examination at 3 months revealed no further orthostatic symptoms and only mild residual right-sided weakness. CONCLUSION: This is the first description of iatrogenic stent-induced dissection of the entire basilar artery that was successfully treated by inflow zone control via tandem intracranial stent deployment.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
3/16. Iatrogenic ileal atresia secondary to clamping of an occult omphalocele.Clamping of an occult omphalocele has led to complete division of an entrapped loop of ileum in two instances. The proximal end has been sealed in the process, producing an iatrogenic ileal atresia. The clinical picture in both instances differed from that usually found with ileal atresia. Escape of a small amount of meconium from the transected cord was noted in one, and the stump of the cord in the other appeared red and engorged. Clamping the umbilical cord routinely at least 5 cm from the abdominal wall is recommended.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
4/16. Acquired FV inhibitors: a needless iatrogenic complication of bovine thrombin exposure.BACKGROUND: FV inhibitors are a largely preventable iatrogenic coagulopathy in which the frequency is increasing in clinical practice. STUDY DESIGN AND methods: Three cases associated with our institution are reported. A systematic review of the medline database was performed, and reference lists were reviewed to identify relevant publications. RESULTS: One hundred twenty-six cases of FV inhibitors have been reported in the world's literature. Eighty-seven have been reported in the last decade, of which two thirds are due to exposure to bovine thrombin. Bovine thrombin-associated FV antibodies develop in 40 to 66 percent of cardiac surgery patients and in 20 percent of neurosurgery patients. Thirty-three percent of reported patients developed bleeding complications. Inhibitors persisted on average 2.3 months. Standard coagulation assays do not reliably predict clinical manifestations. Multimodality therapy, including immunosuppression, is useful for treatment of symptomatic patients. CONCLUSIONS: FV inhibitors are a common complication of bovine thrombin exposure that can have devastating clinical consequences. transfusion medicine specialists and hematologists can play a critical role in reducing the incidence of FV inhibitors by educating the medical community about safer alternative fibrin sealants.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
5/16. Successful treatment of iatrogenic renal artery perforation with an autologous vein-covered stent.A 72-year-old woman developed severe flank pain associated with hemodynamic compromise immediately after a J-curve guidewire was inadvertently advanced into the right renal artery during cardiac catheterization. Contrast extravasation consistent with perforation of the main renal artery was seen on abdominal angiography. The perforation was successfully sealed using a premounted coronary stent that was covered with an autologous antecubital vein. Wide stent patency without aneurismal dilatation was confirmed on a 2-year follow-up renal angiogram.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
6/16. Use of gelatin matrix to rapidly repair diaphragmatic injury during laparoscopy.Iatrogenic diaphragmatic injury during laparoscopy has necessitated intracorporeal suturing and occasionally thoracostomy tube placement. We describe a technique to repair the diaphragm quickly using a novel gelatin thrombin matrix. The matrix can be administered through a trocar or hand-assist device and can rapidly seal small injuries, obviating the need for formal suture repair. The presented case and technique should be considered in selected small diaphragmatic injuries.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
7/16. Successful management of a nonmalignant esophageal perforation with a coated stent.This case report details our experience in the management of an iatrogenic perforation that recurred after two surgical repairs. A self-expanding coated stent was eventually placed to seal the esophageal perforation with significant improvement in the clinical condition of the patient. At 1-year follow-up, the patient is tolerating an oral diet with no evidence of esophageal leak or gastroesophageal reflux. This case report and a literature review suggest that self-expanding coated stents may be a useful salvage option in the management of inveterate nonmalignant esophageal perforations.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
8/16. Iatrogenic aortic dissection during coronary intervention.Iatrogenic acute dissection of the ascending aorta following coronary angiography and percutaneous intervention is rare. Localized aortic dissections have been treated by sealing the entry with a coronary stent. Extensive dissections may require a surgical intervention. We describe a coronary dissection with retrograde extension to the ascending aorta that occurred during angioplasty of the right coronary artery. The extensive dissection, which was limited to the ascending aorta, was successfully treated by stenting of the right coronary artery and monitoring the aortic dissection by means of transesophageal echocardiography.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
9/16. Successful patching of iatrogenic rupture of the fetal membranes.rupture of the fetal membranes is a common, but potentially serious complication of invasive fetal procedures. Quintero described a technique to seal the fetal membrane defect by means of a bloodpatch, usually called 'amniopatch' in this application. The successful use in two consecutive patients with ruptured membranes after a fetoscopic intervention at respectively 17 and 22 weeks' gestational age is described, together with a literature review of published experience.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
10/16. Iatrogenic pseudoaneurysm of femoral artery: case report and literature review.The case of a patient who developed a femoral artery pseudoaneurysm (FAP) following cardiac catheterization is described. It is one of the most troublesome complications after various invasive cardiovascular procedures related to the femoral arterial access site. Iatrogenic pseudoaneurysms (IPA) form when an arterial puncture site fails to seal, allowing arterial blood to ooze into the surrounding tissues and form a pulsatile hematoma. The FAP occurs in 0.8% to 2.2% after interventional procedures. This problem has become more significant due to the exponential growth of interventional cardiology. Doppler flow mapping has been the mainstay of diagnosis. Diagnostic criteria include: swirling color flow in a mass separate from the affected artery, and a typical "to-and-fro" Doppler waveform in the pseudoaneurysm neck. Ultrasound-guided compression repair has replaced the need for surgical repair of FAP. It has been shown to be a safe and cost-effective method for achieving pseudoaneurysm thrombosis. However, it carries considerable drawbacks including long procedure times, discomfort to patients, high recurrence rate in patients receiving anticoagulant therapy and an overall 3.6% complication rate. Recently, percutaneous thrombin injection in the FAP has gained popularity despite complications associated with the initial use of high dose thrombin (average dose of 1,100 IU). The technique was refined when low-dose thrombin injections were studied and proved to have the same efficacy and consistently high success rates (average dose used 192 IU). However, there is a theoretical risk of developing type I IgE-mediated allergic reaction to bovine thrombin. The indications, advantages, disadvantages, and complications of the various treatment modalities are discussed in this report and review of the literature. Other treatments with collagen injection are also discussed in detail.- - - - - - - - - - ranking = 0.25keywords = seal (Clic here for more details about this article) |
