ABSTRACT: Introduction: Iliac vessel trauma (IVT) is traditionally associated with high mortality. We evaluated a modern series of patients with IVT to assess current outcomes and endovascular therapy use. Methods: We performed a retrospective review of the National Trauma Data Bank. Patients with IVT were stratified by blunt and penetrating mechanism and arterial and venous injury. Results: In blunt IVT, there was no significant difference in mortality between those with and without pelvic fractures (odds ratio [OR] 0.61, 95% confidence interval [CI] 0.36-1.06). In penetrating IVT, combined arterial and venous IVT was associated with higher mortality (OR 1.70, 95% CI 1.06-2.70) compared to isolated arterial IVT. Isolated venous IVT was associated with lower mortality (OR 0.55, 95% CI 0.35-0.85) compared to isolated arterial IVT. Endovascular stenting was utilized in 11.3% of blunt IVT with pelvic fractures, 6.3% of blunt IVT without pelvic fractures, and 1.8% of penetrating IVT. Conclusion: Iliac Vessel Trauma has significant mortality. Endovascular intervention for IVT is applied sparingly.

ABSTRACT: The preferred method for revascularization of symptomatic infrapopliteal arterial occlusive disease (IPAD) has traditionally been open vascular bypass. Endovascular techniques have been increasingly applied to treat tibial disease with mixed results. We evaluated the short-term outcome of percutaneous infrapopliteal intervention and compared the different techniques used. A retrospective analysis of consecutive patients undergoing endovascular treatment for infrapopliteal arterial occlusive lesions between 2003 and 2007 in a tertiary teaching hospital was performed. Patient demographic data, indication for intervention, and periprocedural complications were recorded. Periprocedural and short-term outcomes were measured and compared. Forty-nine infrapopliteal arteries in 35 patients were treated. Twenty vessels (15 patients) underwent angioplasty and 29 vessels (20 patients) were treated with atherectomy. Demographic and angiographic characteristics were similar between the groups. Twenty-six patients had concurrent femoral and/or popliteal artery interventions. Overall, technical success was 90% and similar between angioplasty and atherectomy groups (85% versus 93%, p = NS). The vessel-specific complication rate was 10% and was similar between both groups (angioplasty 5% versus atherectomy 14%, p = NS). One dissection occurred in the angioplasty group; one perforation and three thromboembolic events occurred in the atherectomy group. Limb salvage and freedom from reintervention at 6 months were 81% and 68%, respectively, and were not significantly different between the angioplasty and atherectomy groups. Endovascular intervention for IPAD had acceptable periprocedural and short-term success rates in our high-risk patient population. Both atherectomy and angioplasty can be used successfully to treat symptomatic IPAD.

ABSTRACT: Symptomatic atherosclerotic disease of the popliteal artery presents challenges for endovascular therapy. We evaluated the technical success, complications, and midterm outcomes of atherectomy and angioplasty involving the popliteal segment.
We conducted a retrospective review of outcomes of popliteal artery intervention using atherectomy or angioplasty performed between 2003 and 2008.
A total of 56 patients (36% women, age 72.8 +/- 12.2 years, 77% critical limb ischemia) underwent popliteal atherectomy (n = 18) or angioplasty (n = 38). These patients had similar clinical characteristics, TransAtlantic Intersociety Consensus (TASC)/ TASC II classification, mean lesion length, and runoff scores. We observed a trend toward higher rates of technical success defined as <30% residual stenosis after atherectomy compared to angioplasty (94% vs 71%, P = .08). While angioplasty was associated with a higher frequency of arterial dissection (23% vs 0%, P = .003), atherectomy was associated with a higher rate of thromboembolic events (22% vs 0%, P = 0.01). Adjunctive stenting was used more frequently following angioplasty compared to atherectomy (45% vs 6%, P = .005). Thrombolysis was used to treat embolization in 4 patients in the atherectomy group. The improvement in the ankle-brachial index (ABI) was similar between the 2 treatment groups. Primary patency of the popliteal artery at 3, 6, and 12 months was 94%, 88%, and 75% in the atherectomy group and 89%, 82%, and 73% in the angioplasty group (P = not significant [NS]). There were no significant differences in limb salvage and freedom from reintervention at 1 year between the atherectomy and angioplasty groups.
Our experience with popliteal artery endovascular therapy indicates a distinct pattern of procedural complications with atherectomy compared to angioplasty but similar midterm patency, limb salvage, and freedom from intervention.
