Percutaneous management of a bladder-drained pancreas transplant pseudocyst by a transcystic approach.

BACKGROUND: We describe a 35-year-old male type 1 diabetic who underwent a cadaveric combined kidney-bladder-drained pancreas transplant with a duodenocystostomy for exocrine drainage who developed a large pelvic pseudocyst associated with a dilated pancreatic duct and an elevated serum amylase level. METHODS: Due to the risk of surgical revision and the possibility of creating a cutaneous fistula with conventional percutaneous drainage, a pseudocyst-to-bladder drainage was performed. After the procedure, the catheter was capped to allow drainage of the pancreatic secretions into the bladder. RESULTS: After drainage, the patient's serum amylase and lipase normalized along with resolution of the pseudocyst. The tube was removed after 19 weeks with no evidence of a recurrent pseudocyst and a normal serum amylase level. CONCLUSION: The percutaneous pseudocyst-cystostomy obviated the need for surgical revision of the exocrine gland drainage and thus eliminated the morbidity and the potential risk of graft loss associated with such surgery.

Uterine arteriovenous malformation in a patient with recurrent pregnancy loss and a bicornuate uterus. A case report.

BACKGROUND: Arteriovenous malformations (AVM) of the uterus are a rare but potential cause of recurrent pregnancy loss. Only four cases of uterine AVM have resulted in a live birth after conservative management. There is no previous report in which a combination of a müllerian anomaly and an AVM existed concomitantly. CASE: A 33-year-old woman with a history of recurrent pregnancy loss was found to have a coexistent uterine AVM and a bicornuate uterus. The patient underwent arterial embolization and Strassman metroplasty and subsequently had a term pregnancy with a live birth. CONCLUSION: Management of uterine AVM should be individualized, taking into account the patient's desire for future fertility and the stability of her health at presentation.

Infrageniculate bypass graft entrapment.

When failure of vein grafts is due to technical error it is usually observed in the early postoperative period. In this review we describe late failure of five bypass grafts as a result of entrapment of the vein graft caused by an improperly placed tunnel from the femoral to the popliteal artery. Vein graft entrapment may either produce no symptoms or eventually lead to limb ischemia. Pulses and pressures that vary with flexion and extension maneuvers should alert the clinician to the possibility of an entrapment syndrome. The characteristic arteriographic findings observed in these patients include an aberrant course of the vein graft outside the anatomic course of the popliteal artery and position-dependent compression of the graft. The ability of magnetic resonance angiography to demonstrate the arteriographic appearance of the graft as well as the precise location of the compression and to identify structures involved in the entrapment, make it a valuable noninvasive tool in the preoperative assessment of these patients. Treatment options include division of the gastrocnemius muscle, division of the vein graft, or replacement of the vein graft. Familiarity with vein graft entrapment should facilitate its recognition. Careful placement of bypass grafts along the anatomic course of the popliteal artery within the popliteal space will prevent this complication.

Percutaneous transluminal angioplasty: delayed response in neurofibromatosis.

Percutaneous transluminal angioplasty (PTA) was eventually successful in a patient with renal artery stenosis due to neurofibromatosis. Although the immediate postangioplasty appearance showed little improvement, the residual stenosis has completely resolved at 5 months. Delayed response to PTA has been previously documented in other types of vascular disease. Its occurrence in renal artery stenosis due to neurofibromatosis emphasizes the importance of long-term follow-up and may be a factor in the poor short-term results that some have reported for PTA in patients with this condition.

Endovascular management of splenic artery aneurysms and pseudoaneurysms.

Splenic artery aneurysms and pseudoaneurysms are being diagnosed with increasing frequency by modern imaging. The question of appropriate treatment--surgical or endovascular--arises more often. We review our experience and that of others as documented in the literature. The information available suggests that endovascular management of a splenic artery aneurysm or pseudoaneurysm offers a lower complication rate than surgery, but postprocedure imaging to ensure obliteration is recommended.

Effectiveness of a prolapsed bird's nest filter.

PURPOSE: The authors evaluated the variable deployment of the Bird's Nest filter, including frequency and extent of prolapse in clinical use, and analyzed the effects of this variability on clot-trapping efficiency with an in vitro model. MATERIALS AND METHODS: In the clinical placement of 20 filters, the average length of cephalic filter wires from the center of the filter was measured from radiographs obtained immediately after placement. To analyze the effects of prolapse, a variable-rate pump was used to mimic the effects of respiration on IVC flow. Four clot sizes (5 x 20, 5 x 40, 10 x 20, and 10 x 40 mm) were evaluated with four filter configurations with wires stretched to different lengths in a cephalic direction from the center of the filter: 2 cm (normal-tight), 5 cm (normal-loose), 8 cm (moderate prolapse), and to a maximum of 12 cm (maximum prolapse). Ten passes for each clot size were performed with each filter configuration in both the horizontal and vertical positions. The smallest clots were also tested with a slower constant-rate pump. RESULTS: In clinical use, the average length of the filter wire was 5.4 cm (range, 1.2-9.0 cm). With the variable flow pump, the in vitro degree of prolapse did not significantly decrease the trapping efficiency for any but the smallest (5 x 20-mm) clots, for the maximum prolapse configuration in the horizontal position (P = .01). In addition, for these clot sizes, the filter was more efficient with the slower constant rate compared with the faster variable rate; this difference was only statistically significant in the horizontal position for the maximum prolapse configuration (P = .007). CONCLUSION: The results suggest that in clinical practice, a prolapsed Bird's Nest Filter remains effective for all but small clots.

Percutaneous placement of an intercostal central venous catheter for chronic hyperalimentation guided by transhepatic venography.

BACKGROUND AND METHODS: Increased utilization of central venous catheters for hyperalimentation has caused a rise in the incidence of central venous complications including occlusions and stenoses. When this occurs, the continued use of these catheters becomes more difficult. We describe a technique for catheter placement in a patient requiring access for total parenteral nutrition who had extensive central venous occlusion involving both internal jugular veins, both subclavian veins, and the infrorenal inferior vena cava (IVC). RESULTS: A percutaneous transhepatic venous catheter had been placed in a patient with inferior vena caval, subclavian, and internal jugular venous occlusions. The Hickman catheter functioned well until the patient developed fungal sepsis and a large fibrin sheath around the catheter tip creating the need for a new access site. Placement of an intercostal venous catheter was performed using transhepatic venography to map patent collateral veins and microcatheters to access an intercostal route for Hickman placement. CONCLUSIONS: Patients who require long-term central venous access often develop stenotic and occlusive complications in the central venous circulation. Individualized, unique and innovative routes to the central venous circulation must often be utilized to maintain venous access in these patients. Transhepatic venous mapping and microcatheter techniques aid in the finding of alternative sites in these patients with difficult access problems.
